Core lower urinary tract symptom score (CLSS) for the assessment of female lower urinary tract symptoms: a comparative study

Epidemiological survey of post-void residual urine volume in older adult patients in an acute-care hospital: A cross-sectional observational study

AIM

To epidemiologically determine post-void residual urine volume (PVR) and identify the characteristics of "potential" older adult patients with voiding dysfunction in an acute-care hospital.

METHODS

A cross-sectional study was conducted on 614 older adult patients in an acute-care hospital between November 2018 and May 2019. Using portable ultrasound devices, nurses measured the patients' PVR three times after admission. Lower urinary tract symptoms were evaluated using the Core Lower Urinary Tract Symptom Score prior to admission.

RESULTS

A total of 107 older adult patients (17.4%) had episodes of abnormal PVR ≥100 mL. An age of over 75 years (adjusted odds ratio [aOR]: 1.899) and feeling of incomplete emptying (aOR: 4.337) were associated with having at least one episode of abnormal PVR, whereas neurological or circulatory diseases (aOR: 3.699) were associated with having two or three episodes.

CONCLUSIONS

The results showed a high prevalence of abnormal PVR in older adult patients. Screening for PVR in older adult patients aged over 75 years who experience incomplete emptying or neurological or circulatory diseases may help identify those at risk for voiding dysfunction.

Initial experience with prostatic urethral lift versus enucleation of the prostate: a retrospective comparative study

BACKGROUND

This study aimed to assess initial results and patient characteristics of prostatic urethral lift (PUL) compared with those of bipolar transurethral enucleation of the prostate (TUEB) in the treatment of benign prostatic hyperplasia (BPH) in older patients.

METHODS

This retrospective study was conducted at a single institution and involved 25 consecutive patients with BPH who underwent PUL between April 2022 and May 2023. Patient characteristics, operative details, and pre- and postoperative symptom scores were evaluated. The results were compared with those of a previously reported TUEB group (n = 55).

RESULTS

The mean age of the patients in the PUL group was 74.6 years, and the mean prostate volume was 47.5 ml. The PUL procedure significantly improved urinary symptoms, particularly incomplete emptying (p = 0.041), intermittency (p = 0.005), and weak stream (p = 0.001). The PUL group had higher comorbidity scores (p = 0.048) and included older patients (p = 0.002) than the TUEB group. TUEB showed better improvements in some symptoms and maximum flow rate (p = 0.01) than PUL; however, PUL had a shorter operative time and fewer complications than TUEB (p < 0.001).

CONCLUSION

The initial results demonstrate the efficacy and safety of PUL in older patients with BPH. Despite TUEB showing better outcomes in certain aspects than PUL, PUL offers advantages such as shorter operative time and fewer complications. Therefore, PUL can be considered a viable option for high-risk older patients with BPH.

Difference in symptom manifestation between postmenopausal and premenopausal women in acute uncomplicated cystitis: A multi-institutional pilot study

Objectives

We aimed to prospectively compare lower urinary tract symptoms in premenopausal and postmenopausal women with acute uncomplicated cystitis before and after antibiotic therapy.

Materials and methods

This study included adult women with acute uncomplicated cystitis who visited 4 institutions between 2019 and 2020. After registration, we administered oral antibiotics and prospectively documented the changes in lower urinary tract symptoms from the first visit to a follow-up visit at 1 week using the Core Lower Urinary Tract Symptoms Score (CLSS) questionnaire.

Results

After treatment, pyuria disappeared in 60 of the 66 patients (14 premenopausal and 46 postmenopausal). The CLSS total score (range) changed from 13 (3-29) to 4 (0-18) with a significant improvement in all CLSS items. At baseline, nocturia, urgency, and urgency incontinence were more prominent in postmenopausal women than in premenopausal women. In contrast, baseline urethral pain and quality of life index were more severe in premenopausal women than in postmenopausal women. After treatment, the CLSS total score was still higher in postmenopausal women, as reflected by the relatively higher scores for nocturia and urgency, irrespective of the comparable scores for urethral pain and the quality of life index in the 2 groups.

Conclusions

Our results suggest that if storage symptoms persist, they should be carefully interpreted according to menopausal status.

Beneficial Effects of Saw Palmetto Fruit Extract on Urinary Symptoms in Japanese Female Subjects by a Multicenter, Randomized, Double-Blind, Placebo-Controlled Study

Saw palmetto berry extract (SPE) is the most commonly consumed supplement by men with benign prostatic hyperplasia (BPH). The oral administration of SPE was previously shown to significantly attenuate urodynamic symptoms in the hyperactive bladders of female rats by increasing bladder capacity and prolonging the micturition interval. The amelioration of urodynamic symptoms by SPE may be partly attributed to its binding to muscarinic receptors in the urinary bladder and its inhibition of vanilloid receptors on afferent nerves. Therefore, SPE may be pharmacologically effective at mitigating lower urinary tract symptoms (LUTS) in women. The efficacy and safety of a 12-week treatment with SPE in adult women with urinary symptoms were examined herein. The daytime frequency score in the core lower urinary symptom score (CLSS) questionnaire was significantly lower in women with LUTS treated with SPE for 12 weeks than in the placebo group. A subgroup analysis revealed that SPE alleviated the symptoms of daytime frequency (CLSS Q1) and nocturia (CLSS Q2) in a subset of subjects with a CLSS Q5 score of 1 or higher. The daytime frequency of urination in overactive bladder symptom score (OABSS) Q1 was also significantly improved by the SPE treatment. In conclusion, the present study is the first to demonstrate the potential of SPE to mitigate LUTS in adult women.

Flexible cystoscopy can improve anxiety and subjective feelings of bladder cancer patients during follow-up

Introduction

The effect of repeated cystoscopy on bladder cancer (BC) patient anxiety and feelings is rarely evaluated.

Aim

To compare the difference of patients’ anxiety and subjective feelings caused by different cystoscopes.

Material and methods

We prospectively included 192 BC patients who accepted regular cystoscopy follow-up after transurethral resection of bladder tumor (TURBT): 93 in the flexible group and 99 in the rigid group. The method of anesthesia and the order of examinations were consistent between different groups. We analyzed the anxiety level before cystoscopy, the maximum pain during the examination and the change of lower urinary tract symptoms (LUTS) before and after cystoscopy. Meanwhile, we analyzed the rate of gross hematuria and pyuria after cystoscopy. The anxiety and pain levels were evaluated by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and visual analogue scale (VAS). LUTS was reflected by the Core Lower Urinary Tract Symptom Score (CLSS). We distinguished gender during analysis.

Results

The median APAIS score of male patients undergoing flexible or rigid cystoscopy was 8 vs. 12 (p < 0.01), and this result for females was 8 vs. 9 (p = 0.048). The median pain scores for men in the two groups was 1 vs. 2 (p < 0.01), respectively, and this outcome in female patients was 0 vs. 1 (p < 0.01). Patients in the rigid group had more CLSS change (0 vs. 1, p < 0.01). There was no difference in pyuria or gross hematuria rate after examination. Analysis in respective groups showed that men have more severe pain than women, 1 vs. 0 (p = 0.001) in the flexible group and 2 vs. 1 (p = 0.009) in the rigid group.

Conclusions

A flexible cystoscope can improve anxiety and subjective feelings of BC patients during cystoscopy follow-up.

Relationship between Preoperative Neuroradiological Findings and Intraoperative Bulbocavernosus Reflex Amplitude in Patients with Intradural Extramedullary Tumors

The current study aimed to evaluate the relationship between preoperative neuroradiological findings and intraoperative bulbocavernosus reflex (BCR) amplitude in patients with intradural extramedullary tumors. A total of 24 patients with lesions below the 12th thoracic vertebra were included in the analysis. Objective and subjective urinary symptoms were investigated using data obtained from medical records and the core lower urethral symptom score (CLSS) questionnaire. The lesion compression rate was evaluated with MRI. In the epiconus-to-conus medullaris (Epi-CM) group, BCR amplitude changes were found to be correlated with the compression rate (p <0.05). The preoperative CLSS of the group with a BCR amplitude of <50% was worse than that of the group with ≥50% (p <0.01). The group did not experience symptom improvement 6 months postoperatively based on the CLSS. The preoperative CLSS of the group with compression rate of ≥80% on imaging was worse than that of the group with <80% (p <0.05). In the group with preoperative compression rate of ≥80%, CLSS at 1 month and 6 months postoperatively was improved as compared to preoperative CLSS (p <0.01, p <0.05). Hence, BCR amplitude changes are associated with the degree of lesion compression on preoperative images and pre- and postoperative urinary symptoms. Patients with intradural extramedullary Epi-CM lesions with strong compression are likely to present with low BCR amplitude and worsened postoperative symptoms. It is considered that the risk of postoperative urinary symptoms increases even with careful surgical manipulation under these conditions.

Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition)

The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

Psychometric properties of a self-assessment questionnaire concerning symptoms and impairment in urinary tract infections: the UTI-SIQ-8

OBJECTIVES

To validate the urinary tract infection-Symptom and Impairment Questionnaire (UTI-SIQ-8), a questionnaire that consists of four items to assess the symptom severity for dysuria, urgency, frequenc, and low abdominal pain and four items to assess the resulting impairment of activity by UTIs.

DESIGN

Prospective observation study.

SETTING

German primary care practices.

PARTICIPANTS

An unselected population of women with UTI. Women could participate online via a web application for smartphones, smartwatches and tablets or use a paper-and-pencil version.

MAIN OUTCOMES

Psychometric properties of the UTI-SIQ-8 regarding reliability, validity and sensitivity to change by using factor analysis and multilevel and network analysis.

RESULTS

Data from 120 women with a total of 769 symptom reports across 7 days of measurement were analysed. The majority of the participating patients (87/120) used the web application via smartphones or other devices. The reliability of the UTI-SIQ-8 was high, with Cronbach's alpha of .86 at intake; convergent and discriminant validity was satisfactory. Intraclass correlation demonstrated high sensitivity to change, with 68% of the total variance being due to time differences. These daily changes in an individual's symptoms moved parallel with daily changes in the EQ-5D-5L (b=1.68, SE=0.12, p<0.001) and the visual analogue scale (b=0.03, SE=0.003, p<0.001), also highlighting convergent validity with respect to daily changes in symptom severity.

CONCLUSIONS

The present findings support the UTI-SIQ-8 questionnaire as an economic, reliable and valid instrument for the assessment of symptom severity and symptom change in women with uncomplicated UTI. The web application helped patients to report symptoms on a daily basis. These findings may encourage primary care physicians to use the UTI-SIQ-8 in their daily practice and researchers to apply it to studies involving patients with uncomplicated UTI.

Longitudinal change of comprehensive lower urinary tract symptoms and various types of urinary incontinence during robot-assisted radical prostatectomy

AIMS

To clarify longitudinal change of lower urinary tract symptoms (LUTS) and various types of urinary incontinence following robot-assisted radical prostatectomy (RARP) using validated questionnaires.

MATERIALS AND METHODS

The core lower urinary tract symptom score (CLSS) and the International Consultation on Incontinence Questionnaire (ICIQ)-Short Form (SF) questionnaires were administered to 607 consecutive, treatment-naïve men receiving RARP before and after surgery. The time course of comprehensive LUTS and various types of urinary incontinence, including stress-, urgency-, and urinary incontinence with no obvious reason, were evaluated. Continence recovery rates were compared for the different types of incontinence using Cox hazard regression analysis.

RESULTS

After surgery, stress urinary incontinence (SUI) was reported most frequently (32% of cases) as the chief complaint with the most impact on daily life, as assessed by the CLSS questionnaire, followed by urgency urinary incontinence (UUI; 27% of cases). The rates of continence recovery differed among the different types of urinary incontinence, such as after urinating, when dressed, when asleep, when physically active or exercising, when coughing or sneezing, before reaching the toilet, and for no obvious reason. Incontinence for no obvious reason at 1 month after RARP was a strongest prognostic factor of delayed continence recovery (hazard ratio, 0.61; P < 0.0001), whereas patients reporting SUI and UUI gradually regained continence.

CONCLUSIONS

Further time course on continent recovery after RARP would be more precisely predictable based on the incontinence status at one month postoperatively. Especially, incontinence with no obvious reason would be a significant factor for delayed recovery.

Lower urinary tract symptoms in patients with prostate cancer under and after intensity-modulated radiation therapy

OBJECTIVE

The aim of the present study was to collect data on the characteristics, degree, and natural course of urinary complications, as well as self-care for such complications, in patients during and after prostate intensity-modulated radiation therapy (IMRT).

METHODS

Quality of life data were collected retrospectively for all eligible patients who underwent IMRT. In all eligible patients, urinary symptoms were evaluated using questionnaires and face-to-face interview. Participants were asked to respond to a self-administered questionnaire concerning the core lower urinary tract symptom score during the course of IMRT and up to 12 months after the completion of IMRT.

RESULTS

In all, 29 eligible patients were included in the study. The frequency of urinary symptoms increased over of the course of IMRT, decreased at ≥3 months after completion of IMRT, and disappeared 6 months after IMRT. Responses to the questionnaire revealed a variety of approaches to self-care and adaptations by patients to manage urinary symptoms.

CONCLUSIONS

During and after IMRT for localized prostate cancer, patients often developed more frequent urination and urgency than at the start of IMRT, and recovered 3-6 months after the completion of IMRT. Based on the present study, clinicians and nurses could help convey this information to patients and thus offer better support.

Impact of loop-tail ureteral stents on ureteral stent-related symptoms immediately after ureteroscopic lithotripsy: Comparison with pigtail ureteral stents

Purpose

To evaluate urination-related quality of life (QoL) in patients with an indwelling ureteral stent immediately after ureteroscopic lithotripsy (URSL) for upper urinary calculi. We compared the effects of loop-tail and pigtail ureteral stents on urination-related QoL.

Materials and Methods

Of 135 patients who underwent URSL between May 2014 and March 2015 at our hospital, we retrospectively analyzed the records of 70 patients (42 men, 28 women; median age, 63 years) in whom the stent tail was positioned inside the bladder without crossing the midline and who completed the core lower urinary tract symptoms score (CLSS) questionnaire pre- and postoperatively.

Results

There were significant differences in incomplete emptying (p=0.048) and bladder pain (p=0.041) between patients with loop-tail versus pigtail ureteral stents after URSL. In the multivariate analysis, stent type had a stronger association with incomplete emptying (p=0.022) and bladder pain (p=0.018) than age, sex, body mass index, stent side, operation time, diameter of ureteral access sheath, and stent type.

Conclusions

Patients with loop-tail ureteral stents had better urination-related QoL in the immediate post-URSL stage than patients with pigtail stents.

Clinical Guideline for Female Lower Urinary Tract Symptoms

The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery.

The health-related quality of life of Chinese patients with lower urinary tract symptoms in primary care

PURPOSE

The aim of this study was to evaluate the health-related quality of life (HRQOL) of Chinese primary care patients with lower urinary tract symptoms (LUTS).

METHODS

Five hundred and nineteen primary care subjects with LUTS completed a structured questionnaire containing the International Prostate Symptom Score, the adapted Incontinence Impact Questionnaire-7, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Chinese (HK) SF-12 Health Survey Version 2 (SF-12 v2) and the Depression, Anxiety and Stress Scale-21.

RESULTS

LUTS patients had poorer HRQOL for the General Health and the Vitality domains and lower Physical Component Summary scores, but better HRQOL for the Role Emotion domain than the adjusted Hong Kong population norms. Clinical factors associated with poorer HRQOL measured by the SF-12 v2 included having more severe LUTS and having more severe depressive, anxiety and stress symptoms. Socio-demographic factors associated with poorer SF-12 v2 were consistent with those found in the general populations. Clinical and socio-demographic factors associated with poorer HRQOL assessed by condition-specific measures included having more severe LUTS (excluding intermittency and straining), the presence of mixed urinary incontinence, having more severe anxiety and stress symptoms, younger age, being not married, being in employment and having a lower household income.

CONCLUSIONS

LUTS had substantial negative impact on patients' overall health perception and global well-being in Chinese population. A decline in HRQOL might be a key determinant for Chinese patients with LUTS to seek treatment. Patients with nocturia, frequency, urgency or mixed urinary incontinence and younger patients deserve more treatment attention because they appear to have poorer HRQOL.
