Abstract
This study presents a comprehensive investigation of the anatomical features of the levator ani muscle. The levator ani is a critical component of the pelvic floor; however, its intricate anatomy and functionality are poorly understood. Understanding the precise anatomy of the levator ani is crucial for the accurate diagnosis and effective treatment of pelvic floor disorders. Previous studies have been limited by the lack of comprehensive three-dimensional analyses; to overcome this limitation, we analysed the levator ani muscle using a novel 3D digitised muscle-mapping approach based on layer-by-layer dissection. From this examination, we determined that the levator ani consists of overlapping muscle bundles with varying orientations, particularly in the anteroinferior portion. Our findings revealed distinct muscle bundles directly attached to the rectum (LA-re) and twisted muscle slings surrounding the anterior (LA-a) and posterior (LA-p) aspects of the rectum, which are considered functional parts of the levator ani. These results suggest that these specific muscle bundles of the levator ani are primarily responsible for functional performance. The levator ani plays a crucial role in rectal elevation, lifting the centre of the perineum and narrowing the levator hiatus. The comprehensive anatomical information provided by our study will enhance diagnosis accuracy and facilitate the development of targeted treatment strategies for pelvic floor disorders in clinical practice.

Abstract
OBJECTIVE The aim of the study was to evaluate whether the tactile stimulation of the perigenital region together with manual bladder expression (MBE) facilitated the urine stream in cats with acute or chronic upper motor neuron injury (UMNI). ANIMALS 34 cats with UMNI having urinary retention. METHODS All the cats had a complete neurologic examination, which determined the localization of the UMNI between T3 and L3. They were classified as chronic UMNI if the injury had occurred more than 3 days previously. The cats were divided equally into 2 groups: the M group (n = 17) managed with only MBE, and the MT group (17) managed with MBE and tactile stimulation. RESULTS In both groups, all the cats affected by chronic UMNI resumed urination. The time required to obtain a urine stream in the chronic UMNI was 9.3 seconds in the M group and 3.1 seconds in the MT group (P < .05). In the cats affected by acute UMNI, a urine stream was achieved in 54% of the M group and 100% of the MT group (P < .05). The time to obtain a urine stream in the acute UMNI cats was 7.8 seconds in the M group and 3.75 seconds in the MT group (P < .05). CLINICAL RELEVANCE Adding tactile stimulation of the perigenital region to the MBE improved the urine stream in cats affected by UMNI.

Abstract
BACKGROUND The global cesarean delivery rate is high and continuing to increase. A bladder catheter is usually placed for the cesarean section as a distended bladder is assumed to be at higher risk of injury during surgery and to compromise surgical field exposure. Preliminary data suggest that self-bladder emptying (no catheter) at cesarean delivery may have advantages and be safe. OBJECTIVE To evaluate self-bladder emptying to indwelling foley bladder catheterization for a planned cesarean on rate of postpartum urinary retention and maternal satisfaction. STUDY DESIGN A randomized controlled trial was conducted in a tertiary university hospital from January 10 2022 to March 22 2023. 400 participants scheduled for planned cesarean were randomized: 200 each to self-bladder emptying or indwelling foley catheter. The primary outcomes were postpartum urinary retention (overt and covert) and maternal satisfaction with allocated bladder care. Analyses were performed using t test, Mann-Whitney U and Chi-Square or Fisher exact test as appropriate. Logistic regression was used to adjust for characteristic differences. RESULTS Postpartum urinary retention rates were 1/200 (0.6%) vs 0/200 p>0.99 (a solitary case of covert retention) and maternal satisfaction score (0-10 visual numerical rating scale) median [interquartile range] 9 [8-9.75] vs 8 [8-9] p=0.003 for self-bladder emptying vs indwelling foley catheter respectively. Of the secondary outcomes, for self-bladder emptying, recovery to flatus passage, satisfactory ambulation, urination, satisfactory urination, satisfactory breastfeeding, post-cesarean hospital discharge was quickened. Pain score at first urination was decreased and no lower urinary tract symptom was more likely to be reported. Surgical field view, operative blood loss, duration of surgery, culture-derived urinary tract infection, postvoid residual volume and pain score at movement were not different. There was no bladder injury. CONCLUSION Self-bladder emptying increased maternal satisfaction without adversely impacting on postpartum urinary retention. Recovery was enhanced and urinary symptoms were improved. The surgeon was not impeded at operation. No safety concern was found.

Abstract
This study aimed to investigate lower urinary tract symptoms (LUTS) in Turkish adult women and to compare toileting behaviors in women with and without LUTS. This cross-sectional study was conducted in 815 women. The International Consultation on Incontinence Modular Questionnaire - Female LUTS and a toileting behaviors form, created by the authors, were used in evaluations. Nearly 50 % of the women had at least one LUTS, 45.8 % had storage symptoms, 7.4 % had voiding symptoms, and 20.2 % had incontinence symptoms. The rates of premature urination, straining during urination, delayed urination, and sitting on the toilet while urinating were higher in women with LUTS than in women without LUTS (p < .05). The rate of squatting on the toilet while urinating was lower in women with LUTS than those without LUTS (p < .05). Various LUTS were common in adult women. Some toileting behaviors such as premature urination, straining during urination, delayed urination, and sitting on the toilet while urinating were higher in women with LUTS compared to women without LUTS. Since the rate of unhealthy toilet behaviors is higher in women with LUTS, it is important to know unhealthy toilet behaviors in the management of LUTS and to organize training programs to prevent these behaviors and LUTS.

Abstract
Background Lower urinary tract symptoms (LUTS) are prevalent across women's life course. Evidence shows toileting behaviors (TBs) and urinary urge cues are related to LUTS. It is unknown when women start using these behaviors and responding to urinary cues. Methods An online survey was administered to 338 women, 65 years of age and older, to assess the age of onset for 20 TBs from the Toileting Behaviors-Women's Elimination Behavior (TB-WEB) questionnaire, 10 urinary urge cues from the Urinary Cues Questionnaire, and urinary urgency and leakage items from the International Consultation on Incontinence Questionnaire-Overactive Bladder (ICIQ-OAB) Short Form. Descriptive statistics were reported for each TB and urinary cue. A timeline was generated with the average earliest age of onsets for each type of TB, urinary cues, and urinary urgency and leakage symptoms. Results Place preference, delayed voiding, and hovering over toilets away from home were reported to have the earliest ages of onset. Urinary urge cues, premature voiding, and straining to void tended to start after 45 years of age, as did the symptoms of urinary urgency and leakage. The timeline indicated that the earliest place preference and position preference TBs started before 20 years of age. Conclusion Some TBs begin early in life and persist into old age, while other TBs and urinary cues begin later. Bladder health promotion may depend on intervening at specific times in the life course to alter TBs and responses, and potentially making environmental changes.

Abstract
PURPOSE Multimodal therapy has improved survival in genitourinary rhabdomyosarcoma, a rare pediatric cancer. However, little is reported regarding postoperative complications and long-term urinary and sexual function and quality of life. MATERIALS AND METHODS We reviewed records from 1970-2018 to identify patients with genitourinary rhabdomyosarcoma of the bladder, prostate, pelvis, vagina, and uterus. We assessed modes of therapy, and if surgical, the type of resection, reconstruction, and reoperation. Primary outcomes included urinary continence, urinary tract infection occurrence, and stone formation. We also surveyed patients older than 18 years for urinary and sexual function. RESULTS Fifty-one patients were identified for the post-treatment outcomes cohort. All received chemotherapy, 46 (90.2%) underwent surgery, and 34 (67%) received radiation. Twenty-nine patients (56.9%) received trimodal therapy, 17 (33.3%) received chemotherapy/surgery, and 5 (9.8%) received chemotherapy/radiation. Twenty-six had up-front radical surgery (with staged continence mechanism creation); these patients had higher rates of continence, similar rates of urinary tract infection, and higher rates of stone formation compared to those who were organ-spared. A third (4/12) of organ-spared patients underwent additional corrective surgery. Thirty patients with genitourinary rhabdomyosarcoma were surveyed and 14 responded to questionnaires. Overall, urinary complaints were mild, but both male and female respondents reported significant sexual dysfunction. CONCLUSIONS Organ-sparing treatment was more likely to predispose patients to high rates of additional reconstructive surgery due to compromised urological function. In survey results, both men and women reported poor sexual function, but the majority of patients remained satisfied with their urinary function.

Abstract
The functional association between hip joint motion and defaecation/urinary function has attracted considerable research and clinical attention owing to the potential novel approaches for pelvic floor rehabilitation; however, the anatomical basis remains unclear. This study, therefore, aimed to analyse the anatomical basis of force transmission between the obturator internus, a muscle of the hip joint, and the levator ani, a muscle of the pelvic floor. Twenty-three cadavers were used for macroscopic and histological analyses. The three-dimensional structures of the muscles and fascia were recorded using a high-definition camera and a 3D scanner. The arrangement and attachment of the muscle fibres, tendons and fascia were visualised using histological sections stained with Masson's trichrome. The obturator internus and levator ani were in broad contact through the obturator fascia. The height of their contact area was 24.6 ± 9.1 mm. Histologically, the obturator internus and levator ani shared a large area of the obturator fascia, and the obturator fascia provided the attachment of several muscle layers of the levator ani. The contribution of hip joint motion to defaecation/urinary function can be explained by the broad 'planar' contact between the obturator internus and levator ani. This anatomical feature suggests that movement of the obturator internus creates the foundation for the function of the levator ani and contributes to pelvic floor support through the obturator fascia. This study provides an anatomical basis for the effectiveness of the hip muscles in improving defaecation/urinary function by enabling balanced and proper movements.

Abstract
OBJECTIVES Neurokinin 2 receptor (NK2R) agonists may be useful for treating bladder and bowel dysfunction via direct contraction of detrusor and gastrointestinal smooth muscle. The NK2R agonist [Lys5, MeLeu9, Nle10]-NKA(4-10) (LMN-NKA) induces urination and defecation, but also produces the potential side effect of dermal flushing in rats. Although LMN-NKA is a NK2R agonist, it also has affinity for neurokinin 1 receptors (NK1R). Therefore, the goal of this study was to determine the neurokinin receptor (NKR) subtypes responsible for LMN-NKA-induced urination, defecation, and flushing by blocking either NK2Rs or NK1Rs before LMN-NKA administration. METHODS To accomplish this goal, we developed a simple high-throughput 'rapid detection voiding assay' to detect rapid-onset drug-induced urination and defecation in rats. In LMN-NKA dose-response experiments, LMN-NKA (10-100 μg/kg, subcutaneous) was injected and urination, defecation, and flushing were monitored for 30 min. For NKR antagonist experiments, vehicle, the NK2R antagonist GR159897, or the NK1R antagonist CP-99,994 were injected before an acclimation period. Following acclimation, saline or 100 μg/kg LMN-NKA were injected, and behavior was observed for 30 min. RESULTS LMN-NKA produced dose-related increases in urination, defecation, and flushing. Blocking NK2Rs reduced urination and blocked defecation, without affecting flushing. Blocking NK1Rs did not change LMN-NKA-induced urination or defecation but reduced LMN-NKA-induced flushing. CONCLUSIONS Using the rapid detection voiding assay we show that LMN-NKA-induced urination and defecation are mediated by NK2Rs, while flushing is mediated by NK1Rs. Therefore, drugs that are more selective for NK2 vs. NK1Rs should produce rapid-onset urination and defecation without producing the potential side effect of flushing.

Abstract
OBJECTIVES This study aimed to assess the effect sizes, changes over time, and ethnic differences in placebo effects on urinary function among Japanese patients participating in clinical trials. METHODS A meta-analysis of 30 Japanese placebo-controlled clinical trials was conducted to determine the placebo effects on three functions: daily urinary frequency, nocturnal urinary frequency, and average urine volume per void. RESULTS The I-square heterogeneity values for the basic values of the three functions ranged from 84.5% to 97.9%, with differences among trials. Longitudinal analysis (1 to 12 weeks) indicated an enhanced placebo effect for up to 8 weeks and no consistency among trials on nocturnal urinary frequency (p < 0.01), unlike those on daily urinary frequency and average urine volume per void (p = 1.0). Based on the random-effects model, the mean differences in urinary frequency at 4, 8, and 12 weeks were -0.70 (-0.80; -0.60), -1.06 (-1.16; -0.96), and -1.18 (-1.34; -1.01), respectively. Furthermore, the mean difference (95% confidence interval) in nocturnal urinary frequency and volume of urination per void at 12 weeks was -0.63 (-0.94; -0.31) and 9.67 (7.25; 12.1), respectively. CONCLUSIONS My findings suggest an increase in the strength of placebo effects over time (up to 8 weeks). A comparison of my results to those published in previous global reports showed no meaningful differences in placebo effects among ethnic groups. The consistent placebo effect size on urinary function could be an external indicator in clinical trials.

Abstract
Background Idiopathic normal pressure hydrocephalus (iNPH) is characterized by the classic clinical triad of gait, cognitive, and urinary dysfunction, albeit incomplete in a relevant proportion of patients. The clinical findings and evolution of these symptoms have been variably defined in the literature. Objectives To evaluate how the phenomenology has been defined, assessed, and reported, we performed a critical review of the existing literature discussing the phenomenology of iNPH. The review also identified the instrumental tests most frequently used and the evolution of clinical and radiologic findings. Methods The review was divided into 3 sections based on gait, cognitive, and urinary dysfunction. Each section performed a literature search using the terms "idiopathic normal pressure hydrocephalus" (iNPH), with additional search terms used by each section separately. The number of articles screened, duplicates, those meeting the inclusion criteria, and the number of articles excluded were recorded. Findings were subsequently tallied and analyzed. Results A total of 1716 articles with the aforementioned search criteria were identified by the 3 groups. A total of 81 full-text articles were reviewed after the elimination of duplicates, articles that did not discuss phenomenological findings or instrumental testing of participants with iNPH prior to surgery, and articles with fewer than 10 participants. Conclusions "Wide-based gait" was the most common gait dysfunction identified. Cognitive testing varied significantly across articles, and ultimately a specific cognitive profile was not identified. Urodynamic testing found detrusor overactivity and "overactive bladder" as the most common symptom of urinary dysfunction.

Abstract
PURPOSE Bladder diaries are a key source of information about lower urinary tract symptoms (LUTS); however, many patients do not complete them as instructed. Questionnaire-based patient-reported outcome measures (PROMs) are another option for reporting LUTS but may have recall bias. We assessed the strength of the associations between PROMs and a 3-day bladder diary. MATERIALS AND METHODS Symptomatic adults from 6 tertiary care sites completed a 3-day paper bladder diary and 3-, 7-, and 30-day electronic PROMs. We assessed the linear associations between mapped pairs of diary variables and responses to PROM items using biserial and polyserial correlation coefficients with 95% confidence intervals. RESULTS Of 290 enrolled participants, 175 (60%) completed the bladder diary as instructed and at least one corresponding PROM. Linear associations were strongest between the diary and 3-day recall of daytime frequency (r = 0.75) and nighttime frequency (r = 0.69), followed by voids with urgency sensations (r = 0.62), and an item reporting any incontinence (r = 0.56). Linear associations between bladder diary and specific incontinence variables (e.g., stress, urgency) were low to negligible (ranging from r = 0.16-0.39). Linear associations were consistent across the 3-, 7-, and 30-day recall periods. CONCLUSIONS Missing and unusable bladder diary data were common, highlighting the patient burden associated with this method of data collection. A questionnaire-based PROM is a reasonable alternative to a diary for reporting voiding frequency and may offer an easier option for reporting some symptoms.

Abstract
BACKGROUND Limited information on the normal range of urination frequencies in women is available to guide bladder health promotion efforts. OBJECTIVES This study used data from the Boston Area Community Health (BACH) Survey to (a) estimate normative reference ranges in daytime and nighttime urination frequencies in healthy women based on two operational definitions of "healthy" and (b) compare urination frequencies by age, race/ethnicity, and fluid intake. METHODS A secondary analysis of cross-sectional interview data collected from female participants was performed using less restrictive ("healthy") and strict ("elite healthy") inclusion criteria. All analyses were weighted to account for the BACH sampling design. Normative reference values corresponding to the middle 95% of the distribution of daytime and nighttime urination frequencies were calculated overall and stratified by age, race/ethnicity, and fluid intake. Generalized linear regression with a log-link was used to estimate rate ratios of daytime and nighttime urination frequencies by age, race/ethnicity, and fluid intake. RESULTS Of the 2,534 women who completed the BACH follow-up interviews, 1,505 women met healthy eligibility criteria, and 300 met elite healthy criteria. Overall, reference ranges for urination frequencies were 2-10 times/day and 0-4 times/night in healthy women and 2-9 times/day and 0-2 times/night in elite healthy women. Women ages 45-64 years, but not 65+ years, reported a greater number of daytime urination than those aged 31-44 years, whereas women 65+ years reported a greater number of nighttime urination. Black women reported fewer daytime urination and more nighttime urinations than White women. Women who consumed less than 49 oz daily reported fewer daytime and nighttime urinations than those who drank 50-74 oz; drinking 75+ oz had only a small effect on urination frequencies. DISCUSSION Normative reference values for daytime and nighttime urination frequencies were similar in women using strict and relaxed definitions of health. These results indicate a wide range of "normal" urination frequencies, with some differences by age, race/ethnicity, and fluid intake. Future research is needed to examine urination frequencies in minority women and whether fluid intake amount and type influence the development of lower urinary tract symptoms.

Abstract
The aim of this study was to identify an appropriate scoring system for predicting postoperative urinary retention (POUR) after gynaecological laparoscopic surgery for benign disease. We analysed 99 patients who underwent gynaecological laparoscopic surgery for benign disease. All patients were asked to complete self-administered questionnaires, including the International Prostate Symptom Score (IPSS), voiding visual analogue scale (VAS), and Brief Pain Inventory-Korean version. Of the 99 patients, 27 (27.3%) experienced urinary retention at least once, while 72 (72.7%) did not. The preoperative and postoperative IPSS scores were not associated with the development of POUR. However, the voiding VAS score was significantly lower in patients that developed POUR (p = .014). In conclusion, our results show that the voiding VAS score is a simple and useful method for identifying patients at risk of POUR after gynaecologic laparoscopic surgery for benign disease. IMPACT STATEMENTWhat is already known on this subject? Postoperative urinary retention (POUR) is an often underestimated complication defined as inability to void during the postoperative period despite a full bladder. Undetected POUR may lead to complications such as urinary tract infection, bladder distention, and bladder dysfunction. Routine assessment of POUR by bladder ultrasonography in all surgical patients places a larger workload on the nursing staff.What do the results of this study add? Among the self-scoring assessment tools, the voiding VAS provided the most accurate reflection of POUR in patients undergoing gynaecologic laparoscopic surgery for benign disease.What are the implications of these findings for clinical practice and/or further research? As laparoscopy is the most widely employed surgical procedure in gynaecology, our findings could have significant implications for postoperative care in daily clinical practice.

Abstract
PURPOSE We explored the central pathogenesis of overactive bladder (OAB) and the central mechanism of action of sacral neuromodulation (SNM). MATERIALS AND METHODS We prospectively enrolled patients with OAB who chose SNM and healthy controls (HCs). At baseline, all subjects completed a 72-hour voiding diary, OAB symptom score and prefrontal cortex functional near-infrared spectroscopy scan synchronous urodynamic monitoring. All OAB patients were tested after implantation of the SNM electrode, and both success and failure groups were reevaluated. NIRS_KIT software was used to analyze prefrontal activity (p <0.05 and corrected by false discovery rate). SPSS® 22.0 was used to analyze clinical parameters, and p <0.05 was considered statistically significant. RESULTS A total of 16 HC and 20 OAB patients were enrolled. SNM treatment was successful in 18 OAB patients and failed in 2. The parameters of the voiding diary, OAB symptom score and urodynamic monitoring of OAB group were significantly improved after SNM treatment in success group, not in the failure group. Compared with HCs, Brodmann's area 9 (left dorsolateral prefrontal cortex [DLPFC]) was significantly deactivated in the preoperative OAB success group and significantly activated after SNM treatment. Before surgery, compared with the success group, the failure group showed significantly deactivated Brodmann's area 9 (left DLPFC). CONCLUSIONS Our study provides novel neuroimaging evidence for the possible central pathogenesis of OAB (ie abnormal deactivation of the left DLPFC) and the possible central mechanism of action of SNM (ie restore activation of the left DLPFC).

Abstract
PURPOSE Few studies have examined the effects of body position on urination efficiency morphologically. We aimed to dissect out the anatomical changes of pelvic organs during urination in the upright and supine positions by a real-time magnetic resonance imaging (rtMRI) system. METHODS Thirteen healthy male volunteers aged 26-60 years were included in the study. The sagittal real-time two-dimensional images were taken to evaluate urinary efficiency, along with change in six morphological indices at the time of storage and the beginning of voiding, in both upright ant supine positions. RESULTS Urination was more efficient in upright position than in supine position, as expressed by higher average rate of bladder emptying (9.9 ± 4.2 vs. 6.8 ± 2.9 ml/s, p < 0.05) and also by fewer participants showing significant residual urine (1/13 vs. 7/13, p < 0.05). At the onset of voiding in standing position, the levator ani (LA) muscle moves downward and backward followed by descent of the bladder neck and rotation of the prostate around the symphysis. Such changes were expressed by two morphological indices. One was posterior vesicourethral angle at the start of voiding, 152 ± 7 versus 140 ± 1 in upright and supine position (p < 0.05). The other index was the change in angle between the LA line and pubo-coccygeal line in upright and supine position, 9.4 ± 9.9 versus 1.6 ± 7.9 before voiding (p < 0.05) and 30.2 ± 14.0 versus 17.3 ± 12.9 after the start of voiding (p < 0.05). CONCLUSION The dynamic relaxation of LA seemed to be a key movement that enables more efficient urination in standing position than in supine position.

Abstract
All animals possess a plethora of innate behaviors that do not require extensive learning and are fundamental for their survival and propagation. With the advent of newly-developed techniques such as viral tracing and optogenetic and chemogenetic tools, recent studies are gradually unraveling neural circuits underlying different innate behaviors. Here, we summarize current development in our understanding of the neural circuits controlling predation, feeding, male-typical mating, and urination, highlighting the role of genetically defined neurons and their connections in sensory triggering, sensory to motor/motivation transformation, motor/motivation encoding during these different behaviors. Along the way, we discuss possible mechanisms underlying binge-eating disorder and the pro-social effects of the neuropeptide oxytocin, elucidating the clinical relevance of studying neural circuits underlying essential innate functions. Finally, we discuss some exciting brain structures recurrently appearing in the regulation of different behaviors, which suggests both divergence and convergence in the neural encoding of specific innate behaviors. Going forward, we emphasize the importance of multi-angle and cross-species dissections in delineating neural circuits that control innate behaviors.

Abstract
INTRODUCTION To present our novel low submuscular (LSM) pressure regulating balloon (PRB) placement for artificial urinary sphincter (AUS) technique as an alternative to standard approaches with patient-reported satisfaction outcomes. MATERIAL AND METHODS A retrospective review was conducted on patients who underwent an AUS implantation using the LSM PRB placement with transfascial fixation technique from July 2019 to August 2020. Preoperative characteristics were collected. Patients then conducted a postoperative phone interview using an adapted questionnaire to assess satisfaction of device and PRB concealment. RESULTS During the study period, nine patients had undergone AUS placement using the LSM technique by a single surgeon at our private institution. Eight of the nine patients had undergone a radical prostatectomy while the ninth patient developed stress urinary incontinence after radiation treatment for prostate cancer. All patients were 'very satisfied' with PRB placement and concealment with no patients endorsing PRB complications. The majority of patients (78%) were satisfied with the device. One patient was able to palpate the PRB while another patient endorsed mild soreness around the PRB. No surgical revisions were required and there were no surgical complications such as bowel obstruction, herniations, bladder erosions, or vascular injuries. CONCLUSION LSM placement of AUS PRB with transfascial fixation offers an improved technique for balloon placement with decreased risk for complications. This can be performed as a safe, alternative approach to current standard techniques with a high degree of patient satisfaction.

Abstract
OBJECTIVES An enriched environment (EE) has been known to promote structural changes in the brain and enhance learning and emotional performance. However, little is known about the effect of an EE on brain stem functions, such as the micturition function. In this study, we examined whether an EE affects micturition activity in mice. METHODS Male C57BL/6J mice were used. We assessed the micturition activity of freely moving mice using a novel system developed in-house. RESULTS During the dark period, but not light, the EE significantly increased voiding frequency, total voided volume, mean voided volume, voiding duration, mean flow rate, and maximum flow rate compared with the control environment. This EE effect on micturition function was associated with habituation to novel environments in the open-field test, but not with amelioration of motor coordination in the rotarod test. Interestingly, even after the mice were withdrawn from the EE, the improvements in micturition function persisted, while other behavioral changes were abolished. The relative value of voiding frequency and total voided volume during the light period, expressed as a percentage of 24 hours, increased with age when mice were reared in a standard environment. However, this age-related change was not observed in mice reared in an EE. CONCLUSIONS These results suggest that an EE may promote micturition activity during the active phase of C57BL/6J mice, and its effects persist even after withdrawal from the EE. Furthermore, an EE may mitigate dysfunctions in micturition activity, such as polyuria, during the resting phase in aged mice.

Abstract
Objective We herein attempted to select male patients with an elevated nocturnal urinary frequency possibly due to a shortage of AVP. These patients may be good candidates for low-dose oral desmopressin administration. Patients and Methods Serum and spot urine osmolality, electrolytes, serum creatinine, casual blood glucose, plasma brain natriuretic polypeptide (BNP), and plasma AVP were measured at the same time in 97 elderly male patients with urinary symptoms under free water drinking. Results A binary plot of plasma AVP and serum osmolality indicated a region at which patients had relatively lower AVP considering higher serum osmolality. It was tentatively named the desmopressin region. Twenty out of 97 (20.6%) patients were in the desmopressin region. Daily urine output did not exceed 3 L in any patient. Urine osmolality was slightly lower in patients in the desmopressin region. No significant differences were observed in urine volume, urinary frequency, or urination questionnaire scores between both groups. Conclusion AVP-shortage patients may be selected for treatment with oral desmopressin based on measurements of serum osmolality and plasma AVP.

Abstract
Simple Summary The mixing of bovine faeces and urine leads to climate-damaging ammonia emissions. If cattle could be taught to use a latrine, this would reduce the area of emissions, the separation of excreta could easily be accomplished by mechanical means, and animal health could be improved. Attempts to train toileting in cattle have shown limited success. In children, toileting is trained mainly by (i) interrupting voiding that starts outside the toilet, then taking the child to the toilet and rewarding the resumption of excretion, or (ii) placing the child on the toilet, waiting for urination/defecation and rewarding appropriate excretory behaviour. The first method is reported to be more successful. Thus, a similar procedure was evaluated for training latrine use for urination in calves. On 95% of occasions, the calves inhibited or stopped urination when receiving a signal to move to the latrine, and on 65% of occasions, they reinitiated urination in the latrine. Furthermore, during 63% of urinations in the latrine, the calves oriented towards the reward location before any food was delivered, providing additional evidence that calves can be successfully toilet trained with food rewards. Abstract Untrained cattle do not defecate or urinate in defined locations. The toilet training of cattle would allow urine and faeces to be separated and stored, reducing climate-damaging emissions and improving animal health. In a proof-of-concept study, we evaluated a novel protocol for toilet training in cattle. Five heifer calves (and yoked controls) were trained in the voluntary (operant) behaviours of a toileting chain. Then, reflexive urinating responses were incorporated into the chain, with toileting signalled by a tactile (vibratory) stimulus. On 95% of occasions, the calves inhibited/interrupted urination when receiving the stimulus, and on 65% of these occasions, reinitiated urination in the latrine. Furthermore, during 63% of urinations in the latrine, the calves oriented to the reward location before any food was delivered, providing additional evidence that calves can be successfully toilet trained with food rewards. Yoked controls failed to learn most of the operant elements and all the reflexive responses of toilet training. The results show that reflexive behaviours can be incorporated into voluntary toileting sequences with cattle and extend the range of species that can be toilet trained. Future refinement of the protocol to allow training under practical farm conditions offers the potential to mitigate climate damage and improve animal health.

Abstract
PURPOSE We sought to determine the efficacy of dried cranberry on reducing symptoms of overactive bladder in women. MATERIALS AND METHODS Eligible women aged 18 or older with overactive bladder were randomized to either daily dried cranberry powder (500 mg) or placebo (500 mg) and followed for 24 weeks. Efficacy was measured by 3-day voiding diaries and Overactive Bladder Questionnaire Short Form, Patient Perception of Bladder Condition, Sexual Quality of Life-Female and Pelvic Floor Distress Inventory surveys. Statistical analyses were performed by BIOFORTIS using SAS® software version 9.4. RESULTS Of the 98 women who were randomized 77 completed all the visits and 60 were included in the per protocol analysis. Compared to placebo using per protocol analysis the cranberry group showed a significant reduction of daily micturitions (-1.91, 95% CI -3.74--0.88, p=0.0406), urgency episodes (-2.81, 95% CI -4.82--0.80, p=0.0069), and Patient Perception of Bladder Condition scores (-0.66, 95% CI -1.23-0.08, p=0.0258) at 24 weeks of followup. Mean volume per micturition, nocturia and the remaining survey outcomes did not differ significantly between the groups (p >0.05). CONCLUSIONS Daily intake of dried cranberry powder reduced daily micturition by 16.4%, urgency episodes by 57.3% and patient perception of bladder condition by 39.7%. However, an intent-to-treat analysis showed no statistically significant difference between the groups for these measurements (p >0.05). Future larger studies with longer followup periods are needed to further determine the long-term effect of cranberry on overactive bladder.

Abstract
BACKGROUND Complicated transurethral urinary bladder catheterization in female dogs is a commonly encountered urologic problem, often causing inadvertent trauma to the lower urinary tract and breach in aseptic technique. KEY CONCEPTS A novel method for transurethral insertion of urinary catheters in female dogs is described. The main variation from current procedures involves the application of the Seldinger technique with the use of an introduction catheter that is specifically designed to feed into the urethra, and the use of a guidewire to replace the introducer with an indwelling balloon catheter. SIGNIFICANCE The technique presented offers a step-by-step approach that could improve success in urinary catheter placement. This modification may facilitate catheter insertion, be less traumatic, and offer better control of asepsis, especially with challenging urethral catheterization. The technique also offers an easy method to replace the catheter. Application of the technique may reduce catheter-associated urinary tract infections as it addresses certain infection-related risk factors. Prospective validation studies are needed to support its advantages over current urinary catheter placement techniques.

Abstract
AIMS Measurement of self-reported lower urinary tract symptoms (LUTS) typically uses a recall period, for example, "In the past 30 days…." Compared to averaged daily reports, 30-day recall is generally unbiased, but recall bias varies by item. We examined the associations between personal characteristics (eg, age, symptom bother) and 30-day recall of LUTS using items from the Symptoms of Lower Urinary Tract Dysfunction Research Network Comprehensive Assessment of Self-reported Urinary Symptoms questionnaire. METHODS Participants (127 women and 127 men) were recruited from 6 US tertiary care sites. They completed daily assessments for 30 days and a 30-day recall assessment at the end of the study month. For each of the 18 tested items, representing 10 LUTS, the average of the participant's daily responses was modeled as a function of their 30-day recall, the personal characteristic, and the interaction between the 30-day recall and the characteristic in separate general linear regression models, adjusted for sex. RESULTS Nine items representing 7 LUTS exhibited under- or overreporting (recall bias) for at least 25% of participants. Bias was associated with personal characteristics for six LUTS. Underreporting of incontinence was associated with older age, lower anxiety, and negative affect; overreporting of other LUTS was associated with, symptom bother, symptom variability, anxiety, and depression. CONCLUSIONS We identified under- or overreporting that was associated with personal characteristics for six common LUTS. Some cues (eg, less bother and lower anxiety) were related to recall bias in an unexpected direction. Thus, providers should exercise caution when making judgments about the accuracy of a patient's symptom recall based on patient demographic and psychosocial characteristics.

Abstract
Neural circuits extending from the cerebral cortex to the bladder maintain urinary continence and allow voiding when it is socially appropriate. Injuries to certain brain regions produce a specific disruption known as urge incontinence. This neurologic symptom is distinguished by bladder spasticity, with sudden urges to void and frequent inability to maintain continence. The precise localization of neural circuit disruptions responsible for urge incontinence remains poorly defined, partly because the brain regions, cell types, and circuit connections that normally maintain continence are unknown. Here, we review what is known about the micturition reflex circuit and about forebrain control of continence from experimental animal studies and human lesion data. Based on this information, we hypothesize that urge incontinence results from damage to a descending pathway that normally maintains urinary continence. This pathway begins with excitatory neurons in the prefrontal cortex and relays subcortically, through inhibitory neurons that may help suppress reflex micturition during sleep and until it is safe and socially appropriate to void. Identifying the specific cell types and circuit connections that constitute the continence-promoting pathway, from the forebrain to the brainstem, will help us better understand why some brain lesions and neurodegenerative diseases disrupt continence. This information is needed to pave the way toward better treatments for neurologic patients suffering from urge incontinence.

Abstract
OBJECTIVES To assess if a standard hydration protocol will achieve voided volumes over 150 mL and more reliable uroflowmetry results. METHODS This is a single-blinded crossover study of 40 patients with benign prostatic obstruction and 34 healthy volunteers. Subjects were enrolled prospectively between January and March 2019. All subjects performed two randomly ordered uroflowmetry tests. One test was performed when subjects sensed their bladder was full and had the urge to void and another one after emptying the bladder and ingesting 1.5 L of water within 1 hour (prehydration). Uroflowmetry parameters were compared between the benign prostatic obstruction group and the healthy volunteers. Uroflowmetry results were categorized as reliable, residual, and suboptimal with respect to voided volumes. This study has been registered in the UMIN Clinical Trials Registry (UMIN000035446). RESULTS The benign prostatic obstruction group and the healthy volunteer group presented no difference in respect of uroflowmetry test reliability (P = .459). Uroflowmetry results were reliable in 58 (78.4%) subjects in the prehydrated group and was reliable in 30 (40.5%) subjects in the non-prehydrated group. The difference was statistically significant (P < .05). In the benign prostatic obstruction group and healthy volunteer group, the rate of reliable uroflowmetry tests was significantly higher with prehydration (P < .05). The comparative analysis of uroflowmetry parameters between tests performed with and without prehydration revealed higher values in the prehydrated group (voided volume, maximum flow rate, average flow rate, and postvoiding residual volume; P < .05). CONCLUSION Prehydration of patients with 1.5 L of water within 1 hour before uroflowmetry improves uroflowmetry outcomes. By this hydration protocol, the chance to obtain a voided volume over 150 mL is increased significantly.

Abstract
PRACTICAL RELEVANCE One of the reasons why cats enjoy such a high level of popularity as domestic pets is the fact that they are clean. When there is a breakdown in this fastidious behaviour and elimination occurs outside of the litter box or tray, the strain on the cat-owner bond and on human relationships within the household can be considerable. EVIDENCE BASE Indoor elimination behaviour is one of the most common reasons for cat owners to seek professional advice and there is a wide range of articles, book chapters and research papers that reference it. In many cases the topic of urination and defecation in unacceptable indoor locations is considered in combination with the deposition of urine or faeces as a marker, but this review focuses purely on problematic elimination. An accompanying article in this special issue discusses urine spraying. CLINICAL CHALLENGES Indoor elimination problems necessitate a clinical approach combining knowledge from the fields of physical and emotional health and an understanding of normal feline behaviour. They also require comprehensive history-taking skills as well as effective communication skills and a degree of empathy for owners who are often finding their pet's behaviour very distressing. GLOBAL IMPORTANCE Early diagnosis of physical health disorders that are associated with indoor elimination is extremely important in terms of safeguarding feline welfare. As we become more aware of the interplay between physical and emotional health, the significance of identifying suboptimal social and physical environments in terms of optimising the welfare of domestic cats is also being recognised. The potential for indoor elimination problems to cause considerable human distress highlights the importance of the concepts of One Health and One Welfare.

Abstract
BACKGROUND We evaluated the optimal high-density lipoprotein cholesterol level for benign prostatic hyperplasia (BPH) prevention in men not taking statin medication using a large historical cohort. METHODS We initially selected 130 454 men who underwent health checkups in 2009 from the National Health Information Database of the National Health Insurance Service. After excluding 36 854 men with BPH in 2009, and 45 061 men for statin use, 48 539 men were ultimately included in the analysis. A Kaplan-Meier analysis and multivariable Cox regression analysis was performed to assess the optimal high-density lipoprotein cholesterol level for preventing BPH. RESULTS High-density lipoprotein cholesterol levels were less than 40 mg/dL in 7431 (15.3%) men, 40 to 49 in 15 861 (32.7%), 50 to 59 in 15 328 (27.5%), and greater than or equal to 60 in 11 919 (24.6%). The overall cumulative incidence of BPH was 4.4%, 8.7%, 13.0%, and 17.8% at the 1-, 2-, 3-, and 4-year follow-up periods, respectively. In multivariable analysis, high-density lipoprotein greater than or equal to 60 mg/dL were significantly associated with a decreased incidence of BPH, as were age, residence, income, body mass index, diabetes, hypertension, triglyceride, and increased annual clinic visits, especially in men in their 40s. CONCLUSION Elevated serum high-density lipoprotein cholesterol levels were negatively associated with BPH incidence. In addition, maintaining high-density lipoprotein greater than or equal to 60 mg/dL was associated with a decreased BPH incidence compared with high-density lipoprotein less than 40 mg/dL, especially in men in their 40s.

Abstract
Simple Summary In diverse settings, human presence and handling influence the behavior and physiology of other animals, often causing increased vigilance and stress, especially if the human is unfamiliar. Domestic dogs are unusual in that human interaction often reduces stress and behavioral signs of stress. Nevertheless, there is some evidence that the sex of an unfamiliar person can influence canine behavior. To determine whether sex of an unfamiliar walker might influence the behavior of dogs at an animal shelter, we observed 100 dogs during leash walks and recorded all occurrences of scent-marking behaviors. Male dogs urinated at higher rates when walked by unfamiliar women than when walked by unfamiliar men. Female dogs urinated at similar rates when walked by unfamiliar men and unfamiliar women. Sex of walker also influenced urinary posture in male dogs. Both male and female dogs were more likely to defecate when walked by unfamiliar women than when walked by unfamiliar men. Based on our findings, and those of others, we suggest that the sex of all observers and handlers be reported in behavioral studies of dogs and considered in behavioral evaluations at animal shelters, where results can impact whether or not a dog is made available for adoption. Abstract Interactions with humans influence the behavior and physiology of other animals, and the response can vary with sex and familiarity. Dogs in animal shelters face challenging conditions and although contact with humans typically reduces stress and behaviors associated with stress, evidence indicates that shelter dogs react differently to unfamiliar men and women. Given that some aspects of canine scent-marking behavior change under fearful conditions, we examined whether sex of an unfamiliar walker would influence scent-marking behavior of 100 shelter dogs during leash walks. Male dogs urinated at higher rates when walked by unfamiliar women than when walked by unfamiliar men; female dogs urinated at similar rates when walked by unfamiliar women and unfamiliar men. Sex of walker influenced urinary posture in male dogs, but not in female dogs. Both male and female dogs were more likely to defecate when walked by unfamiliar women than by unfamiliar men. Based on our findings that shelter dogs behave differently in the presence of unfamiliar men and women, we suggest that researchers conducting behavioral studies of dogs record, consider in analyses, and report the sex of observers and handlers as standard practice. We also recommend recording the sex of shelter staff present at behavioral evaluations because the results of these evaluations can impact dog welfare.

Abstract
PURPOSE This retrospective cohort study evaluates the characteristics of patients who presented to the emergency department with acute urinary retention. MATERIALS AND METHODS Using the Healthcare Cost and Utilization Project State Emergency Department Databases we conducted a retrospective cohort study of patients who presented to emergency departments in Florida between 2005 and 2015. Male patients age 45 years or older who presented with diagnosis codes for acute urinary retention and lower urinary tract symptoms/benign prostatic hyperplasia were considered. Information was collected on age, race/ethnicity, primary insurance and rural-urban commuting area codes. RESULTS The mean age for males presenting with acute urinary retention was 72.2 years, which was 10.6 years older than those presenting for nonurological complaints (p <0.001). Multivariable analysis adjusted for measured confounders found all covariates to be significant. The risk of presenting to the emergency department for acute urinary retention from lower urinary tract symptoms/benign prostatic hyperplasia increased with age, with the 75 to less than 85-year-old age group at the highest risk (OR 15.96, p <0.001). Other factors associated acute urinary retention included African American (OR 1.15, p <0.001) or Hispanic (OR 1.75, p <0.001) race, Medicare (OR 1.27, p <0.001) or private (OR 1.33, p <0.001) insurance, and urban rural-urban commuting area codes (OR 1.31, p <0.001). CONCLUSIONS Male patients who presented to the emergency department for acute urinary retention with benign prostatic hyperplasia were more likely to be older, of nonwhite race, have Medicare or private insurance, and live in more urban areas. These data suggest that African American and Hispanic patients may be untreated or under treated for benign prostatic hyperplasia in the outpatient setting, resulting in an increased risk of presentation to the emergency department with acute urinary retention.

Abstract
This scoping review explores the state of science regarding women’s toileting behaviors, gaps in knowledge, and areas for future research. Online databases were searched to identify papers published in English between January 2010 through July 2019; the search identified 25 articles. The Toileting Behaviors–Women’s Elimination Behaviors scale has been published in four validated language versions and used in 17 of the 25 studies. The most frequent behaviors include concern about public toilet cleanliness, delaying urination when busy or away from home, and using different toileting postures at and away from home. Determinants of toileting behaviors include environmental factors, chronic health conditions, and cognitive/psychological factors. Associations were found between toileting behaviors and lower urinary tract symptoms and between toileting postures and uroflowmetric parameters and post-void residual volume. Strategies that address modifiable determinants of toileting behaviors should be developed and tested in future research. Furthermore, little is known about the toileting behaviors and bladder health in older women and women from developing countries. Rigorous studies are needed to better understand the underlying mechanisms of toileting behaviors, the nature of associations between toileting behaviors and lower urinary tract symptoms, and effects of the environment on women’s toileting behaviors.

Abstract
Understanding the complex neural mechanisms controlling urinary bladder activity is an extremely important topic in both neuroscience and urology. Simultaneously recording of the bladder activity and neural activity in related brain regions will largely advance this field. However, such recording approach has long been restricted to anesthetized animals, whose bladder function and urodynamic properties are largely affected by anesthetics. In our recent report, we found that it is feasible to record bladder pressure (cystometry) and the related cortical neuron activity simultaneously in freely moving mice. Here, we aimed to demonstrate the use of this combined method in freely moving mice for recording the activity of the pontine micturition center (PMC), a more difficultly approachable small region deeply located in the brainstem and a more popularly studied hub for controlling bladder function. Interestingly, we found that the duration of urination events linearly correlated to the time course of neuronal activity in the PMC. We observed that the activities of PMC neurons highly correlated with spike-like increases in bladder pressure, reflecting bladder contractions. We also found that anesthesia evoked prominent changes in the dynamics of the Ca2+ signals in the PMC during the bladder contraction and even induced the dripping overflow incontinence due to suppression of the neural activity in the PMC. In addition, we described in details both the system for cystometry in freely moving mice and the protocols for how to perform this combined method. Therefore, this work provides a powerful approach that enables the simultaneous measurement of neuronal activity of the PMC or any other brain sites and bladder function in freely behaving mice. This approach offers a promising possibility to examine the neural mechanisms underlying neurogenic bladder dysfunction.

Abstract
PURPOSE Perineal urethrostomy is a viable option for many complex urethral strictures. However, to our knowledge no comparison with anterior urethroplasty regarding patient reported outcome measures has been published. We compared these groups using a large multi-institution database. MATERIALS AND METHODS We performed a retrospective study of anterior urethroplasty in the TURNS (Trauma and Urologic Reconstructive Network of Surgeons) database. The anterior urethroplasty cohort was defined by long strictures greater than 6 cm. We compared demographic, clinical, urinary and sexual characteristics using validated patient reported outcome measures between patients treated with long stricture anterior urethroplasty and those who underwent perineal urethrostomy. RESULTS Of the 131 patients 92 treated with long stricture anterior urethroplasty and 39 treated with perineal urethrostomy met study inclusion criteria. The cumulative incidence of failure at 2 years was 30.2% (95% CI 18.3-47.3) for long stricture anterior urethroplasty and 14.5% (95% CI 4.8-39.1) for perineal urethrostomy (p = 0.09). Compared to baseline metrics, patients who underwent long stricture anterior urethroplasty and perineal urethrostomy had similar improvements in urinary function and stable sexual function after surgery. CONCLUSIONS Patients reported improvement in urinary function after perineal urethrostomy with no deleterious effect on sexual function. These patient reported outcome measures were comparable to those of long stricture anterior urethroplasty. Perineal urethrostomy failure rates were similar to those of long stricture anterior urethroplasty.

Abstract
BACKGROUND Circumstances such as the inability to pass a retrograde urinary catheter or a lack of surgeon availability may prevent immediate relief of urethral obstruction in dogs. In such situations, a cystostomy tube may be placed with ultrasound guidance to allow urinary diversion until further treatment is possible. KEY FINDINGS A case of a 5-year-old male neutered Swiss Mountain dog with an obstructive urolith at the level of the os penis is used to describe the technique. Multiple attempts to pass a urinary catheter under sedation were unsuccessful. A pigtail cystostomy tube was placed with ultrasound guidance to allow urinary diversion. The dog was discharged from the hospital within 2 days after scrotal urethrostomy and the dog made a full recovery. Ultrasound-guided placement of a pigtail cystostomy tube was straightforward and without complications. SIGNIFICANCE Ultrasound-guided placement of a pigtail cystostomy tube may be beneficial as it is not technically challenging, can be performed rapidly, and may avoid the need for general anesthesia. Additionally, ultrasound is readily available and an inexperienced ultrasonographer can easily locate the urinary bladder. This report serves to provide a detailed technique of ultrasound-guided placement of a pigtail cystostomy tube in dogs for emergency urinary diversion.

Abstract
Mutations in leucine-rich-repeats and immunoglobulin-like-domains 2 (LRIG2) or in heparanase 2 (HPSE2) cause urofacial syndrome, a devastating autosomal recessive disease of functional bladder outlet obstruction. It has been speculated that urofacial syndrome has a neural basis, but it is unknown whether defects in urinary bladder innervation are present. We hypothesized that urofacial syndrome features a peripheral neuropathy of the bladder. Mice with homozygous targeted Lrig2 mutations had urinary defects resembling those found in urofacial syndrome. There was no anatomical blockage of the outflow tract, consistent with a functional bladder outlet obstruction. Transcriptome analysis revealed differential expression of 12 known transcripts in addition to Lrig2, including 8 with established roles in neurobiology. Mice with homozygous mutations in either Lrig2 or Hpse2 had increased nerve density within the body of the urinary bladder and decreased nerve density around the urinary outflow tract. In a sample of 155 children with chronic kidney disease and urinary symptoms, we discovered novel homozygous missense LRIG2 variants that were predicted to be pathogenic in 2 individuals with non-syndromic bladder outlet obstruction. These observations provide evidence that a peripheral neuropathy is central to the pathobiology of functional bladder outlet obstruction in urofacial syndrome, and emphasize the importance of LRIG2 and heparanase 2 for nerve patterning in the urinary tract.

Abstract
PURPOSE The objective of this study was to assess toileting behaviors in community dwelling women. MATERIALS AND METHODS Women 18 years old or older were recruited through a national registry of research volunteers. They were asked to complete validated questionnaires assessing urinary symptoms and toileting behaviors, specifically place preference for voiding, convenience voiding, delayed voiding, straining during voiding and position preference for voiding. The PPBC (patient perception of bladder condition) was administered to assess the participant impression of bladder health. Analyses were done to determine the prevalence of each toileting behavior reported to occur sometimes or more often as well as differences in toileting behaviors in women with vs without self-perceived bladder problems based on the PPBC response. RESULTS The 6,695 women who completed the questionnaires were 18 to 89 years old (mean ± SD age 41.4 ± 15). Of the women 79.9% identified as white and 71.0% were college educated. Of the women 6,613 (98.8%) reported a place preference for voiding. The 3,552 women (53.1%) who reported a bladder problem were more likely to report convenience voiding, delayed voiding and strained voiding behaviors. While 6,657 women (99.4%) reported sitting to void at home only 5,108 (76.2%) reported sitting when using public toilets. CONCLUSIONS Certain toileting behaviors, of which some may be considered unhealthy, were common in this sample of women and most were associated with a perception of bladder problems. Voiding positions other than sitting were frequently used when away from home. These data have important implications for defining bladder health and implementing behavior based interventions for women with lower urinary tract symptoms.

Abstract
Several studies have used a variety of neuroimaging techniques to measure brain activity during the voiding phase of micturition. However, there is a lack of consensus on which regions of the brain are activated during voiding. The aim of this meta-analysis is to identify the brain regions that are consistently activated during voiding in healthy adults across different studies. We searched the literature for neuroimaging studies that reported brain co-ordinates that were activated during voiding. We excluded studies that reported co-ordinates only for bladder filling, during pelvic floor contraction only, and studies that focused on abnormal bladder states such as the neurogenic bladder. We used the activation-likelihood estimation (ALE) approach to create a statistical map of the brain and identify the brain co-ordinates that were activated across different studies. We identified nine studies that reported brain activation during the task of voiding in 91 healthy subjects. Together, these studies reported 117 foci for ALE analysis. Our ALE map yielded six clusters of activation in the pons, cerebellum, insula, anterior cingulate cortex (ACC), thalamus, and the inferior frontal gyrus. Regions of the brain involved in executive control (frontal cortex), interoception (ACC, insula), motor control (cerebellum, thalamus), and brainstem (pons) are involved in micturition. This analysis provides insight into the supraspinal control of voiding in healthy adults and provides a framework to understand dysfunctional voiding. Clin.

Abstract
OBJECTIVE To analyse possible associations between men's likelihood of contacting a general practitioner (GP) for urological symptoms and the persistence of the symptoms, the influence on daily activities and the level of concern about the symptoms. DESIGN Web-based nationwide cross-sectional questionnaire study. SETTING The general population in Denmark. SUBJECTS 48,910 randomly selected men aged 20+ years. MAIN OUTCOME MEASURES Urological symptom prevalence and odds ratios for GP contact with urological symptoms in regard to concern for the symptom, influence on daily activities and the persistence of the symptom. RESULTS Some 23,240 men responded to the questionnaire, yielding a response rate of 49.8%. The prevalence of at least one urological symptom was 59.9%. Among men experiencing at least one urological symptom almost one-fourth reported contact to general practice regarding the symptom. Approximately half of the symptoms reported to be extremely concerning were discussed with a GP. CONCLUSION Increased symptom concern, influence on daily activities and long-term persistence increased the likelihood of contacting a GP with urological symptoms. This research points out that guidelines for PSA testing might be challenged by the high prevalence of urological symptoms. Key points The decision process of whether to contact the general practitioner (GP) is influenced by different factors, but contradictory results has been found in triggers and barriers for help-seeking with urological symptoms. • Increased symptom concern, influence on daily activities and long-term persistence consistently increased the likelihood of contacting a general practitioner with urological symptoms in men. • Only 50% of the symptoms reported to be extremely concerning were however discussed with the GP. • Guidelines for PSA testing might be challenged by the high prevalence of urological symptoms.

Abstract
PURPOSE Wolfram syndrome is a neurodegenerative disorder characterized by childhood onset diabetes mellitus, optic nerve atrophy, diabetes insipidus, hearing impairment, and commonly bladder and bowel dysfunction. We hypothesized that there is an association between a smaller pons, which contains the pontine micturition center, and abnormal lower urinary tract function. MATERIALS AND METHODS Patients with genetically confirmed Wolfram syndrome attended an annual multidisciplinary research clinic. Subjects underwent noninvasive urodynamic testing and brain magnetic resonance imaging, and completed validated patient reported outcome measures. Bowel and bladder diaries were completed before visits. Age and gender corrected linear and logistic mixed effects models were used to correlate pons volume, corrected for whole brain size, to urodynamic and patient reported outcomes. RESULTS A total of 36 patients attended 142 visits between 2010 and 2016. Mean age was 16.9 years (range 7 to 30) and 64% of patients were female. Functional bladder capacity was decreased in 31% of the patients, normal in 54% and increased in 14%. Of the patients 44% and 54% had abnormal uroflowmetry and post-void residual, respectively, on at least 1 occasion. There was no increase through time in incidence of lower urinary tract dysfunction. Decreased pons volume was associated with increased post-void residual (p = 0.048) and higher PinQ (Pediatric Incontinence Questionnaire) score (p = 0.011), indicating lower quality of life and higher levels of dysfunction. CONCLUSIONS A significant number of children, adolescents and young adults with Wolfram syndrome have objective evidence of lower urinary tract dysfunction. Decreased pons volume is associated with more abnormal urinary function and lower quality of life in patients with Wolfram syndrome.

Abstract
Objective: We performed a retrospective case-control study of vaginal delivery at term without epidural anesthesia to identify clinical predictions of postpartum urinary retention (PUR). Methods: We reviewed the obstetric records of all singleton vaginal deliveries at Japanese Red Cross, Katsushika Maternity Hospital form January 2016 through December 2017. Results: There were 58 women (2.4%) complicated by PUR and 2391 women without PUR. A multivariate analysis revealed nulliparity, instrumental delivery, and episiotomy as independent risk factors for PUR (nulliparity: adjusted OR 2.39, 95%CI 1.2-4.8, p = 0.01; instrumental delivery: 3.53, 95%CI 1.9-6.7, p < .01, episiotomy: adjusted OR 1.96, 95%CI 1.0-3.8, p = .04). While, urination (or urethral catheterization) within 1 hour before delivery revealed as independent prevention factor for PUR (adjusted OR 0.54, 95%CI 0.30-0.99, p = .048). Conclusions: The risk factors identified in our institute seemed to approximately similar to those observed in the institutes capable of performing epidural anesthesia. In addition, urination just before delivery seemed to be an independent prevention factor for PUR.

Abstract
Lower urinary tract symptoms (LUTS) are highly prevalent in women, and are expected to impose a growing burden to individuals and society as the population ages. The predominance of research related to LUTS has focused on underlying pathology, disease mechanisms, or the efficacy of treatments for women with LUTS. Although this research has been vital for helping to reduce or ameliorate LUTS conditions, it has done little to prevent the onset of LUTS. Health promotion and prevention require an expansion of scientific inquiry beyond the traditional paradigm of studying disease mechanisms and treatment to the creation of an evidence base to support recommendations for bladder health promotion and, in turn, prevention of LUTS. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) introduced the concept of prevention as an important priority for women's urologic research as a prelude to supporting the formation of the Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium. In this article, we introduce the PLUS research consortium to the scientific community; share the innovative paradigms by which the consortium operates; and describe its unique research mission: to identify factors that promote bladder health across the life course and prevent the onset of LUTS in girls and women.

Abstract
Lack of access to acceptable sanitation facilities can expose individuals, particularly women, to physical, social, and mental health risks. While some of the challenges have been documented, standard metrics are needed to determine the extent to which women have urination- and defecation-related concerns and negative experiences. Such metrics also are needed to assess the effectiveness of interventions to mitigate them. We developed a sanitation insecurity measure to capture the range and frequency of women's sanitation-related concerns and negative experiences. Research was conducted in rural Odisha, India with women across various life course stages to reflect a range of perspectives. This paper documents the mixed data collection methods and the exploratory and confirmatory factor analyses we employed to arrive at a final measure. The final sanitation insecurity measure includes 50 items across seven factors that reflect the physical environment, the social environment, and individual-level constraints. Most factor scores were significantly higher for unmarried women and for women who lacked access to functional latrines, indicating social and environmental influence on experiences. This measure will enable researchers to evaluate how sanitation insecurity affects health and to determine if and how sanitation interventions ameliorate women's concerns and negative experiences associated with sanitation.

Abstract
AIMS To describe toileting behaviors working women habitually use and investigate behaviors associated with lower urinary tract symptoms (LUTS), especially urinary urgency with or without leakage. METHODS Non-pregnant female employees of a large academic medical center 18 years and over were eligible to complete an online survey about bladder health and toileting behaviors. RESULTS One hundred eighty-two women participated in the survey. The majority were white (83.52%), married (52.49%), had ≥1 pregnancy (54.40%), and in excellent health (93.41%). The average age and body mass index were 47.28 ± 13.56 years and 27.92 ± 6.78, respectively. The sample was further sub-divided into two groups: urinary urgency (N = 119) or no urinary urgency symptoms (N = 51). Habitual toileting behaviors for these groups (N = 170) included: sitting to urinate at home (98.24%), emptying the bladder completely (88.82%), emptying the bladder before leaving home (80.00%), and sitting to urinate when away from home (68.82%). Logistic regression analysis showed age increased the odds of urinary urgency (aOR 1.06, 95%CI 1.02-1.09). Women who waited too long to urinate at work (aOR 7.85, 95%CI 1.57-39.24) and wore panty liners for urinary leakage (aOR 2.86, 95%CI 1.25-6.56) had greater odds of urinary urgency than women who did neither. CONCLUSIONS Most habitual toileting behaviors were not associated with urinary urgency except waiting too long to urinate when at work. Logistic regression revealed significant relationships among health-related factors, personal characteristics, behaviors, and urinary urgency. LUTS in women is both a women's health and occupational health issue.

Abstract
PURPOSE Bulbar urethroplasty outcomes studies have shown low but significant rates of post-void dribbling and ejaculatory dysfunction. The bulbospongiosus muscle is involved with the expulsion of seminal fluid and urine from the bulbar urethra and, thus, we hypothesized that performing urethroplasty using a technique that does not split the muscle may result in better postoperative patient reported ejaculatory function and less post-void dribbling. MATERIALS AND METHODS We performed a multi-institutional matched, case-control analysis comparing men treated with a bulbospongiosus sparing technique to men treated with the traditional nonbulbospongiosus sparing technique. Preoperative and postoperative (3 to 12 months) ejaculatory function was assessed using the 4 ejaculatory questions of the Male Sexual Health Questionnaire short form as well as a patient perception questionnaire. Post-void dribbling was assessed using a validated urethroplasty questionnaire. RESULTS A total of 25 patients who underwent bulbospongiosus sparing urethroplasty and 25 who underwent nonbulbospongiosus sparing urethroplasty were matched by total preoperative Male Sexual Health Questionnaire score, age, and performance of excision and primary anastomosis. The bulbospongiosus sparing and nonbulbospongiosus sparing groups had similar postoperative total Male Sexual Health Questionnaire scores (15.24 vs 15.40, respectively, p=0.90) and there were no significant postoperative questionnaire score changes in either group (bulbospongiosus sparing 14.56 to 15.24, p=0.4; nonbulbospongiosus sparing 14.64 vs 15.40, p=0.44). Individual responses to the Male Sexual Health Questionnaire were analyzed and no statistically significant difference was found between the groups. Rates of postoperative post-void dribbling and perception of ejaculatory function were similar between the groups. CONCLUSIONS Sparing the bulbospongiosus muscle during urethroplasty does not seem to have a significant impact on patient reported ejaculatory function or post-void dribbling compared with nonbulbospongiosus sparing urethroplasty at early followup.

Abstract
OBJECTIVES Urinary disorders are generally well understood, but there are few reports on the urinary status of people living in unusual climates such as the polar regions. We studied the impact of living conditions on the urinary status of members of the Japanese Antarctic Research Expedition. METHODS This prospective study enrolled 12 consenting members of the wintering party stationed at the Syowa Station in Antarctica between November 2012 and March 2014. The subjects completed questionnaires (the International Prostate Symptom Score [IPSS], Overactive Bladder Syndrome Score [OABSS] and Pittsburgh Sleep Quality Index [PSQI]) and kept daily voiding dairies for 3 days consecutively every 2 months. RESULTS Compared with baseline values, the mean scores on all the questionnaires decreased during the stay in Antarctica, from 3.42 to 2.31 for the IPSS, 1.25 to 0.986 for the OABSS, and 4.58 to 3.78 on the PSQI. A significant difference was noted in the scores of seven subjects with a 3 point or more decrease in IPSS score and five members with a decrease less than 3 points (-2.22 vs 0.448, P = 0.0416). CONCLUSION This is the first survey of the urinary status of people living in a polar environment. The findings obtained by questionnaires and voiding dairies indicated that urination and sleep status did not worsen during the stay in Antarctica.

Abstract
INTRODUCTION Clinic based uroflowmetry is commonly used in the diagnosis and management of lower urinary tract symptoms. AUA (American Urological Association) guidelines recommend 2 separate uroflowmetry tests with a voided volume greater than 150 ml for accurate interpretation. We characterized the interpretability of a series of uroflowmetry tests done at our institution and hypothesized that a significant number were noninterpretable because of inadequate urine volume. METHODS Uroflowmetry results were collected from male patients at the UH (University of Utah Hospital) and VAMC (George Wahlen Veterans Affairs Medical Center) urology clinics between August 31, 2014 and September 30, 2014. Average time to perform uroflowmetry was determined. Tests with a volume of 150 ml or less were classified as noninterpretable. Data were characterized using descriptive statistics. RESULTS During the study period 169 tests were collected, including 104 at UH and 65 at VAMC, of which 107 (63%) were noninterpretable. An estimated total of 1,452 tests were performed at UH and VAMC within a 12-month period. Average time to perform uroflowmetry by health care workers was 2 minutes 18 seconds. The estimated time loss per year for medical personnel due to noninterpretable uroflow studies was 35 hours. CONCLUSIONS More than 50% of clinic based uroflowmetry tests at our institution had a voided volume of 150 ml or less and were deemed noninterpretable per AUA guidelines. Current clinic based uroflowmetry testing strategies are inefficient and wasteful. Reliable, accurate alternatives to clinic based uroflowmetry for the diagnosis and management of lower urinary tract symptoms should be explored.

Abstract
PURPOSE An obstructive urinary flow pattern is frequently seen after tubularized incised plate urethroplasty for hypospadias. However, the significance of this finding has not been determined and long-term results are few. We describe postoperative long-term uroflowmetry results after puberty in males who underwent tubularized incised plate urethroplasty in childhood. MATERIALS AND METHODS A total of 126 boys underwent tubularized incised plate urethroplasty for distal penile to mid shaft hypospadias at Queen Silvia Children's Hospital in Gothenburg between 1999 and 2003. Of the patients 48 were toilet trained at surgery. We report on 40 patients who had data available at 2 and 12 months postoperatively, 7 years postoperatively and at puberty (median age 15.0 years, range 13.7 to 17.1). Of the patients 31 had distal and 9 had mid penile hypospadias. Clinical examination, urinary medical history, uroflowmetry and ultrasound measuring residual urine were performed. Maximum urinary flow was correlated to age and voided volume, using Miskolc nomograms for comparison of percentiles. RESULTS At 1 year postoperatively 15 boys (37.5%) had normal urinary flow (above 25th percentile), compared to 16 (40%) at 7 years and 38 (95%) at puberty (p <0.0001). Improvement was significant in patients with distal (p <0.0001) and mid penile hypospadias (p = 0.008), as well as in patients who did (p = 0.0078) and did not undergo intervention (p <0.0001). During followup 5 patients underwent meatotomy due to obstructive symptoms and 4 underwent dilation. Three of these 9 patients had lichen sclerosus. CONCLUSIONS There is great potential for normalization of urinary flow at puberty for boys with hypospadias treated with tubularized incised plate urethroplasty. Unless symptoms occur, a conservative approach seems preferable.

Abstract
BACKGROUND Invasive urodynamic tests are used to investigate men with lower urinary tract symptoms (LUTS) and voiding dysfunction to determine a definitive objective diagnosis. The aim is to help clinicians select the treatment that is most likely to be successful. These investigations are invasive and time-consuming. OBJECTIVES To determine whether performing invasive urodynamic investigation, as opposed to other methods of diagnosis such as non-invasive urodynamics or clinical history and examination alone, reduces the number of men with continuing symptoms of voiding dysfunction. This goal will be achieved by critically appraising and summarising current evidence from randomised controlled trials related to clinical outcomes and cost-effectiveness. This review is not intended to consider whether urodynamic tests are reliable for making clinical diagnoses, nor whether one type of urodynamic test is better than another for this purpose.The following comparisons were made.• Urodynamics versus clinical management.• One type of urodynamics versus another. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, issue 10), MEDLINE (1 January 1946 to Week 4 October 2014), MEDLINE In-Process and other non-indexed citations (covering 27 November 2014; all searched on 28 November 2014), EMBASE Classic and EMBASE (1 January 2010 to Week 47 2014, searched on 28 November 2014), ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (searched on 1 December 2014 and 3 December 2014, respectively), as well as the reference lists of relevant articles. SELECTION CRITERIA Randomised and quasi-randomised trials comparing clinical outcomes in men who were and were not investigated with the use of invasive urodynamics, or comparing one type of urodynamics against another, were included. Trials were excluded if they did not report clinical outcomes. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial quality and extracted data. MAIN RESULTS We included two trials, but data were available for only 339 men in one trial, of whom 188 underwent invasive urodynamic studies. We found evidence of risk of bias, such as lack of outcome information for 24 men in one arm of the trial.Statistically significant evidence suggests that the tests did change clinical decision making. Men in the invasive urodynamics arm were more likely to have their management changed than men in the control arm (proportion with change in management 24/188 (13%) vs 0/151 (0%), risk ratio (RR) 39.41, 95% confidence interval (CI) 2.42 to 642.74). However, the quality of the evidence was low.Low-quality evidence indicates that men in the invasive urodynamics group were less likely to undergo surgery as treatment for voiding LUTS (164/188 (87%) vs 151/151 (100%), RR 0.87, 95% CI 0.83 to 0.92).Investigators observed no difference in urine flow rates before and after surgery for LUTS (mean percentage increase in urine flow rate, 140% in invasive urodynamic group vs 149% in immediate surgery group, P value = 0.13). Similarly, they found no differences between groups with regards to International Prostate Symptom Score (IPSS) (mean percentage decrease in IPSS score, 58% in invasive urodynamics group vs 59% in immediate surgery group, P value = 0.22).No evidence was available to demonstrate whether differences in management equated to improved health outcomes, such as relief of symptoms of voiding dysfunction or improved quality of life.No evidence from randomised trials revealed the adverse effects associated with invasive urodynamic studies. AUTHORS' CONCLUSIONS Although invasive urodynamic testing did change clinical decision making, we found no evidence to demonstrate whether this led to reduced symptoms of voiding dysfunction after treatment. Larger definitive trials of better quality are needed, in which men are randomly allocated to management based on invasive urodynamic findings or to management based on findings obtained by other diagnostic means. This research will show whether performance of invasive urodynamics results in reduced symptoms of voiding dysfunction after treatment.

Abstract
AIM The impact of the original International Children's Continence Society (ICCS) terminology document on lower urinary tract (LUT) function resulted in the global establishment of uniformity and clarity in the characterization of LUT function and dysfunction in children across multiple healthcare disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric LUT function. METHODS A variety of worldwide experts from multiple disciplines within the ICCS leadership who care for children with LUT dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. Additionally, contributions and feedback from the multidisciplinary ICCS membership were solicited. RESULTS Following a review of the literature over the last 7 years, the ICCS experts assembled a new terminology document reflecting current understanding of bladder function and LUT dysfunction in children using the resources from the literature review, expert opinion and ICCS member feedback. CONCLUSIONS The present ICCS terminology document provides a current and consensus update to the evolving terminology and understanding of LUT function in children. Neurourol.

Abstract
PURPOSE Normal voiding in neurologically intact patients is triggered by the release of tonic inhibition from suprapontine centers, allowing the pontine micturition center to trigger the voiding reflex. Supraspinal mechanisms of voluntary voiding in humans are just beginning to be described via functional neuroimaging. We further elucidated brain activity processes during voiding using functional magnetic resonance imaging in normal females to gain better understanding of normal voiding as well as changes that may occur in voiding dysfunction. MATERIALS AND METHODS We screened 13 healthy premenopausal female volunteers using baseline clinic urodynamics to document normal voiding parameters. We then recorded brain activity via functional magnetic resonance imaging and simultaneous urodynamics, including the pressure flow voiding phase. After motion correction of functional magnetic resonance images we performed activation and connectivity analyses in 10 subjects. RESULTS Group analysis revealed consistent activation areas, including regions for motor control (cerebellum, thalamus, caudate, lentiform nucleus, red nucleus, supplementary motor area and post-central gyrus), emotion (anterior/posterior cingulate gyrus and insula), executive function (left superior frontal gyrus) and a focal region in the pons. Connectivity analysis demonstrated strong interconnectivity of the pontine micturition center with many short-range and long-range cortical clusters. CONCLUSIONS Our study is one of the first reports of brain activation centers associated with micturition initiation in normal healthy females. Results show activation of a brain network consisting of regions for motor control, executive function and emotion processing. Further studies are planned to create and validate a model of brain activity during normal voiding in women.
