Abstract
We have demonstrated in canines that somatic nerve transfer to vesical branches of the inferior hypogastric plexus (IHP) can be used for bladder reinnervation after spinal root injury. Yet, the complex anatomy of the IHP hinders the clinical application of this repair strategy. Here, using human cadavers, we clarify the spatial relationships of the vesical branches of the IHP and nearby pelvic ganglia, with the ureteral orifice of the bladder. Forty-four pelvic regions were examined in 30 human cadavers. Gross post-mortem and intra-operative approaches (open anterior abdominal, manual laparoscopic, and robot-assisted) were used. Nerve branch distances and diameters were measured after thorough visual inspection and gentle dissection, so as to not distort tissue. The IHP had between 1 to 4 vesical branches (2.33 ± 0.72, mean ± SD) with average diameters of 0.51 ± 0.06 mm. Vesical branches from the IHP arose from a grossly visible pelvic ganglion in 93% of cases (confirmed histologically). The pelvic ganglion was typically located 7.11 ± 6.11 mm posterolateral to the ureteral orifice in 69% of specimens. With this in-depth characterization, vesical branches from the IHP can be safely located both posterolateral to the ureteral orifice and emanating from a more proximal ganglionic enlargement during surgical procedures.

Abstract
In pilot work we showed that somatic nerve transfers can restore motor function in long-term decentralized dogs. We continue to explore the effectiveness of motor reinnervation in 30 female dogs. After anesthesia, 12 underwent bilateral transection of coccygeal and sacral (S) spinal roots, dorsal roots of lumbar (L)7, and hypogastric nerves. Twelve months post-decentralization, 8 underwent transfer of obturator nerve branches to pelvic nerve vesical branches, and sciatic nerve branches to pudendal nerves, followed by 10 months recovery (ObNT-ScNT Reinn). The remaining 4 were euthanized 18 months post-decentralization (Decentralized). Results were compared to 18 Controls. Squat-and-void postures were tracked during awake cystometry. None showed squat-and-void postures during the decentralization phase. Seven of 8 ObNT-ScNT Reinn began showing such postures by 6 months post-reinnervation; one showed a return of defecation postures. Retrograde dyes were injected into the bladder and urethra 3 weeks prior to euthanasia, at which point, roots and transferred nerves were electrically stimulated to evaluate motor function. Upon L2-L6 root stimulation, 5 of 8 ObNT-ScNT Reinn showed elevated detrusor pressure and 4 showed elevated urethral pressure, compared to L7-S3 root stimulation. After stimulation of sciatic-to-pudendal transferred nerves, 3 of 8 ObNT-ScNT Reinn showed elevated urethral pressure; all showed elevated anal sphincter pressure. Retrogradely labeled neurons were observed in L2-L6 ventral horns (in laminae VI, VIII and IX) of ObNT-ScNT Reinn, versus Controls in which labeled neurons were observed in L7-S3 ventral horns (in lamina VII). This data supports the use of nerve transfer techniques for restoration of bladder function.

Abstract
This study aimed to identify potential lateralization of bladder function. Electrical stimulation of spinal roots or the pelvic nerve’s anterior vesical branch was performed bilaterally in female dogs. The percent difference between the left and right stimulation-induced increased detrusor pressure was determined. Bladders were considered left or right-sided if differences were greater or less than 25% or 10%. Based on differences of 25%, upon stimulation of spinal roots, bladders were left-sided in 17/44 (38.6%), right-sided in 12/44 (27.2%) and bilateral in 15/44 (34.2%). Using ± 10%, 48% had left side dominance (n = 21/44), 39% had right side dominance (n = 17/44), and 14% were bilateral (n = 6/44). With stimulation of the pelvic nerve’s anterior vesical branch in 19 dogs, bladders were left-sided in 8 (42.1%), right-sided in 6 (31.6%) and bilateral in 5 (26.3%) using 25% differences and left side dominance in 8 (43%), right sided in 7 (37%) and bilateral in 4 (21%) using 10% differences. These data suggest lateralization of innervation of the female dog bladder with left- and right-sided lateralization occurring at similar rates. Lateralization often varied at different spinal cord levels within the same animal.

Abstract
By clustering patients with the urologic chronic pelvic pain syndromes (UCPPS) into homogeneous subgroups and associating these subgroups with baseline covariates and other clinical outcomes, we provide opportunities to investigate different potential elements of pathogenesis, which may also guide us in selection of appropriate therapeutic targets. Motivated by the longitudinal urologic symptom data with extensive subject heterogeneity and differential variability of trajectories, we propose a functional clustering procedure where each subgroup is modeled by a functional mixed effects model, and the posterior probability is used to iteratively classify each subject into different subgroups. The classification takes into account both group-average trajectories and between-subject variabilities. We develop an equivalent state-space model for efficient computation. We also propose a cross-validation based Kullback-Leibler information criterion to choose the optimal number of subgroups. The performance of the proposed method is assessed through a simulation study. We apply our methods to longitudinal bi-weekly measures of a primary urological urinary symptoms score from a UCPPS longitudinal cohort study, and identify four subgroups ranging from moderate decline, mild decline, stable and mild increasing. The resulting clusters are also associated with the one-year changes in several clinically important outcomes, and are also related to several clinically relevant baseline predictors, such as sleep disturbance score, physical quality of life and painful urgency.

Abstract
This study determined the effect of pelvic organ decentralization and reinnervation 1 yr later on the contribution of muscarinic and purinergic receptors to ex vivo, nerve-evoked, bladder smooth muscle contractions. Nineteen canines underwent decentralization by bilateral transection of all coccygeal and sacral (S) spinal roots, dorsal roots of lumbar (L)7, and hypogastric nerves. After exclusions, 8 were reinnervated 12 mo postdecentralization with obturator-to-pelvic and sciatic-to-pudendal nerve transfers then euthanized 8-12 mo later. Four served as long-term decentralized only animals. Controls included six sham-operated and three unoperated animals. Detrusor muscle was assessed for contractile responses to potassium chloride (KCl) and electric field stimulation (EFS) before and after purinergic receptor desensitization with α, β-methylene adenosine triphosphate (α,β-mATP), muscarinic receptor antagonism with atropine, or sodium channel blockade with tetrodotoxin. Atropine inhibition of EFS-induced contractions increased in decentralized and reinnervated animals compared with controls. Maximal contractile responses to α,β-mATP did not differ between groups. In strips from decentralized and reinnervated animals, the contractile response to EFS was enhanced at lower frequencies compared with normal controls. The observation of increased blockade of nerve-evoked contractions by muscarinic antagonist with no change in responsiveness to purinergic agonist suggests either decreased ATP release or increased ecto-ATPase activity in detrusor muscle as a consequence of the long-term decentralization. The reduction in the frequency required to produce maximum contraction following decentralization may be due to enhanced nerve sensitivity to EFS or a change in the effectiveness of the neurotransmission.

Abstract
We determined the effect of pelvic organ decentralization and reinnervation 1 yr later on urinary bladder histology and function. Nineteen canines underwent decentralization by bilateral transection of all coccygeal and sacral (S) spinal roots, dorsal roots of lumbar (L)7, and hypogastric nerves. After exclusions, eight were reinnervated 12 mo postdecentralization with obturator-to-pelvic and sciatic-to-pudendal nerve transfers, then euthanized 8-12 mo later. Four served as long-term decentralized only animals. Before euthanasia, pelvic or transferred nerves and L1–S3 spinal roots were stimulated and maximum detrusor pressure (MDP) recorded. Bladder specimens were collected for histological and ex vivo smooth muscle contractility studies. Both reinnervated and decentralized animals showed less or denuded urothelium, fewer intramural ganglia, and more inflammation and collagen, than controls, although percent muscle was maintained. In reinnervated animals, pgp9.5+ axon density was higher compared with decentralized animals. Ex vivo smooth muscle contractions in response to KCl correlated positively with submucosal inflammation, detrusor muscle thickness, and pgp9.5+ axon density. In vivo, reinnervated animals showed higher MDP after stimulation of L1–L6 roots compared with their transected L7–S3 roots, and reinnervated and decentralized animals showed lower MDP than controls after stimulation of nerves (due likely to fibrotic nerve encapsulation). MDP correlated negatively with detrusor collagen and inflammation, and positively with pgp9.5+ axon density and intramural ganglia numbers. These results demonstrate that bladder function can be improved by transfer of obturator nerves to pelvic nerves at 1 yr after decentralization, although the fibrosis and inflammation that developed were associated with decreased contractile function.

Abstract
PURPOSE We analyzed a series of novel noninvasive urinary biomarkers for their ability to objectively monitor the longitudinal clinical status of patients with urological chronic pelvic pain syndrome. MATERIALS AND METHODS Baseline, 6 and 12-month urine samples were collected (216) and used to quantify vascular endothelial growth factor, vascular endothelial growth factor (VEGF) receptor 1 (R1), neutrophil gelatinase associated lipocalin (NGAL), matrix metalloproteinase-2, matrix metalloproteinase (MMP)-9, and MMP-9/NGAL complex by enzyme-linked immunosorbent assays. Patient symptom changes were classified as improved, stable or worse using a functional clustering algorithm. Proportional odds models were used to evaluate the association between symptom change and urinary biomarkers. RESULTS Across all sampled participants, longitudinal decreases in normalized VEGF concentration (pg/μg) were associated with pain severity improvement, and decreases in MMP-9, NGAL and VEGF-R1 concentration (pg/ml) as well as NGAL normalized concentration were associated with improved urinary symptoms. Longitudinal decreases in normalized VEGF-R1 were associated with pain improvement in patients with moderate widespreadness, no bladder symptoms and no painful filling. Lower baseline normalized VEGF-R1 concentration was associated with pain improvement in patients with pelvic pain only. Higher baseline MMP-9/NGAL levels were associated with pain and urinary improvement across all participants. Moreover, longitudinal increases in MMP-2 concentration was associated with improved pain in men and patients with painful filling. CONCLUSIONS Our results suggest these urinary biomarkers may be useful in monitoring urological chronic pelvic pain syndrome symptom changes with respect to both urinary severity and pain severity. With further testing, they may represent objective biological measures of urological chronic pelvic pain syndrome progression and/or resolution while also providing insight into the pathophysiology of urological chronic pelvic pain syndrome.

Abstract
OBJECTIVE Previous patient surveys have shown that patients with spinal cord or cauda equina injuries prioritize recovery of bladder function. The authors sought to determine if nerve transfer after long-term decentralization restores bladder and sphincter function in canines. METHODS Twenty-four female canines were included in this study. Transection of sacral roots and hypogastric nerves (S Dec) was performed in 6 animals, and 7 animals underwent this procedure with additional transection of the L7 dorsal roots (L7d+S Dec). Twelve months later, 3 L7d+S Dec animals underwent obturator-to-pelvic nerve and sciatic-to-pudendal nerve transfers (L7d+S Dec+Reinn). Eleven animals served as controls. Squat-and-void behaviors were tracked before and after decentralization, after reinnervation, and following awake bladder-filling procedures. Bladders were cystoscopically injected with Fluoro-Gold 3 weeks before euthanasia. Immediately before euthanasia, transferred nerves were stimulated to evaluate motor function. Dorsal root ganglia were assessed for retrogradely labeled neurons. RESULTS Transection of only sacral roots failed to reduce squat-and-void postures; L7 dorsal root transection was necessary for significant reduction. Three L7d+S Dec animals showing loss of squat-and-void postures post-decentralization were chosen for reinnervation and recovered these postures 4-6 months after reinnervation. Each showed obturator nerve stimulation-induced bladder contractions and sciatic nerve stimulation-induced anal sphincter contractions immediately prior to euthanasia. One showed sciatic nerve stimulation-induced external urethral sphincter contractions and voluntarily voided twice following nonanesthetized bladder filling. Reinnervation was confirmed by increased labeled cells in L2 and the L4-6 dorsal root ganglia (source of obturator nerve in canines) of L7d+S Dec+Reinn animals, compared with controls. CONCLUSIONS New neuronal pathways created by nerve transfer can restore bladder sensation and motor function in lower motor neuron-lesioned canines even 12 months after decentralization.

Abstract
AIMS The Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network initiated a second observational cohort study-the Symptom Patterns Study (SPS)-to further investigate the underlying pathophysiology of Urologic Chronic Pelvic Pain Syndrome (UCPPS) and to discover factors associated with longitudinal symptom changes and responses to treatments. METHODS This multisite cohort study of males and females with UCPPS features a run-in period of four weekly web-based symptom assessments before a baseline visit, followed by quarterly assessments up to 36 months. Controls were also recruited and assessed at baseline and 6 months. Extensive clinical data assessing urological symptoms, nonurological pain, chronic overlapping pain syndromes, and psychosocial factors were collected. Diverse biospecimens for biomarker and microbiome studies, quantitative sensory testing (QST) data under multiple stimuli, and structural and functional neuroimaging scans were obtained under a standardized protocol. RESULTS Recruitment was initiated (July 2015) and completed (February 2019) at six discovery sites. A total of 620 males and females with UCPPS and 73 Controls were enrolled, including 83 UCPPS participants who re-enrolled from the first MAPP Network cohort study (2009-2012). Baseline neuroimaging scans, QST measures, and biospecimens were obtained on 578 UCPPS participants. The longitudinal follow-up of the cohort is ongoing. CONCLUSIONS This comprehensive characterization of a large UCPPS cohort with extended follow-up greatly expands upon earlier MAPP Network studies and provides unprecedented opportunities to increase our understanding of UCPPS pathophysiology, factors associated with symptom change, clinically relevant patient phenotypes, and novel targets for future interventions.

Abstract
Chronic overlapping pain conditions (COPCs) are characterized by aberrant central nervous system processing of pain. This "centralized pain" phenotype has been described using a large and diverse set of symptom domains, including the spatial distribution of pain, pain intensity, fatigue, mood imbalances, cognitive dysfunction, altered somatic sensations, and hypersensitivity to external stimuli. Here, we used 3 cohorts, including patients with urologic chronic pelvic pain syndrome, a mixed pain cohort with other COPCs, and healthy individuals (total n = 1039) from the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network to explore the factor structure of symptoms of centralized pain. Using exploratory and confirmatory factor analysis, we identified 2 general factors in all 3 cohorts, one characterized by a broad increased sensitivity to internal somatic sensations,environmental stimuli, and diffuse pain, termed Generalized Sensory Sensitivity, and one characterized by constitutional symptoms-Sleep, Pain, Affect, Cognition, Energy (SPACE). Longitudinal analyses in the urologic chronic pelvic pain syndrome cohort found the same 2-factor structure at month 6 and 1 year, suggesting that the 2-factor structure is reproducible over time. In secondary analyses, we found that Generalized Sensory Sensitivity particularly is associated with the presence of comorbid COPCs, whereas SPACE shows modest associations with measures of disability and urinary symptoms. These factors may represent an important and distinct continuum of symptoms that are indicative of the centralized pain phenotype at high levels. Future research of COPCs should accommodate the measurement of each factor.

Abstract
INTRODUCTION To determine rates of spontaneous ureteral stone passage in patients with indwelling ureteral stents, and to identify factors associated with the spontaneous passage of stones while a ureteral stent is in place. MATERIALS AND METHODS From our institutional database, we identified patients who underwent ureteroscopic procedures for stone disease between January 1, 2013 and March 1, 2015. We compared the rates of spontaneous stone passage between patients who had previously undergone ureteral stent placement and those who had not. In patients with indwelling stents, multivariate logistic regression was performed to identify factors associated with spontaneous stone passage. RESULTS A total of 194 patients met inclusion criteria. Spontaneous stone passage rates were similar in the stented (17/119, 14%) and non-stented (15/75, 20%) groups (p = 0.30). In bivariate analysis of stented patients, smaller stone size (p < 0.001) and distal stone location (p = 0.01) were significantly associated with spontaneous stone passage. Multivariate logistic regression analysis of stented patients showed that only small stone size was significantly associated with the likelihood of stone passage (p = 0.01), whereas stent duration, stone location, and stone laterality were not. CONCLUSIONS A small, but clinically significant percentage of ureteral stones pass spontaneously with a ureteral stent in place. Small stone size is associated with an increased likelihood of spontaneous passage in patients with indwelling stents. These findings may help to identify patients who can potentially avoid additional surgical procedures for definitive stone removal after ureteral stent placement.

Abstract
OBJECTIVE To examine a series of candidate markers for urological chronic pelvic pain syndrome (UCPPS), selected based on their proposed involvement in underlying biological processes so as to provide new insights into pathophysiology and suggest targets for expanded clinical and mechanistic studies. METHODS Baseline urine samples from Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network study participants with UCPPS (n = 259), positive controls (PCs; chronic pain without pelvic pain, n = 107) and healthy controls (HCs, n = 125) were analysed for the presence of proteins that are suggested in the literature to be associated with UCPPS. Matrix metalloproteinase (MMP)-2, MMP-9, MMP-9/neutrophil gelatinase-associated lipocalin (NGAL) complex (also known as Lipocalin 2), vascular endothelial growth factor (VEGF), VEGF receptor 1 (VEGF-R1) and NGAL were assayed and quantitated using mono-specific enzyme-linked immunosorbent assays for each protein. Log-transformed concentration (pg/mL or ng/mL) and concentration normalized to total protein (pg/μg) values were compared among the UCPPS, PC and HC groups within sex using the Student's t-test, with P values adjusted for multiple comparisons. Multivariable logistic regression and receiver-operating characteristic curves assessed the utility of the biomarkers in distinguishing participants with UCPPS and control participants. Associations of protein with symptom severity were assessed by linear regression. RESULTS Significantly higher normalized concentrations (pg/μg) of VEGF, VEGF-R1 and MMP-9 in men and VEGF concentration (pg/mL) in women were associated with UCPPS vs HC. These proteins provided only marginal discrimination between UCPPS participants and HCs. In men with UCCPS, pain severity was significantly positively associated with concentrations of MMP-9 and MMP-9/NGAL complex, and urinary severity was significantly positively associated with MMP-9, MMP-9/NGAL complex and VEGF-R1. In women with UCPPS, pain and urinary symptom severity were associated with increased normalized concentrations of MMP-9/NGAL complex, while pain severity alone was associated with increased normalized concentrations of VEGF, and urinary severity alone was associated with increased normalized concentrations of MMP-2. Pain severity in women with UCPPS was significantly positively associated with concentrations of all biomarkers except NGAL, and urinary severity with all concentrations except VEGF-R1. CONCLUSION Altered levels of MMP-9, MMP-9/NGAL complex and VEGF-R1 in men, and all biomarkers in women, were associated with clinical symptoms of UCPPS. None of the evaluated candidate markers usefully discriminated UCPPS patients from controls. Elevated VEGF, MMP-9 and VEGF-R1 levels in men and VEGF levels in women may provide potential new insights into the pathophysiology of UCPPS.

Abstract
OBJECTIVE To assess life expectancy and biopsy outcomes in men undergoing prostate biopsy at an academic medical center. METHODS We analyzed men who underwent prostate biopsy at our medical center between July 2012 and June 2014. Long-term other-cause mortality risk was determined using survival tables. Indications for biopsy and biopsy outcomes were assessed, and compared among men with varying mortality risks. RESULTS A total of 417 men underwent prostate biopsy, in whom 14-year other-cause mortality risk ranged from 9% to 74%. One hundred ninety-three men (46.3%) were considered low-mortality risk (<40% risk of 14-year mortality), 131 (31.4%) intermediate risk (41%-55% 14-year mortality), and 93 (22.3%) high risk (>55% 14-year mortality). Of the 417 patients who underwent biopsy, 149 (35.7%) were found to have prostate cancer. There was no significant difference in the rate of positive biopsies (P = .72), distribution of Gleason scores (P = .60), or percentage of positive biopsy cores (P = .74) between mortality risk groups. However, by UCSF Cancer of the Prostate Risk Assessment score, there was significant trend toward higher-risk prostate cancer in men with intermediate and high-mortality risk (P = .04). CONCLUSION In this analysis, a large number of men with limited life expectancies underwent prostate biopsy. The majority of these men had negative biopsies or low-risk cancers, suggesting that they were unlikely to benefit from biopsy. To avoid potentially unnecessary prostate biopsies, the practitioner must give serious consideration to a patient's age and medical comorbidities before making a recommendation as to whether biopsy should be performed.

Abstract
PURPOSE We describe bladder associated symptoms in patients with urological chronic pelvic pain syndromes. We correlated these symptoms with urological, nonurological, psychosocial and quality of life measures. MATERIALS AND METHODS Study participants included 233 women and 191 men with interstitial cystitis/bladder pain syndrome or chronic prostatitis/chronic pelvic pain syndrome in a multicenter study. They completed a battery of measures, including items asking whether pain worsened with bladder filling (painful filling) or whether the urge to urinate was due to pain, pressure or discomfort (painful urgency). Participants were categorized into 3 groups, including group 1-painful filling and painful urgency (both), 2-painful filling or painful urgency (either) and 3-no painful filling or painful urgency (neither). RESULTS Of the men 75% and of the women 88% were categorized as both or either. These bladder characteristics were associated with more severe urological symptoms (increased pain, frequency and urgency), a higher somatic symptom burden, depression and worse quality of life (3-group trend test each p<0.01). A gradient effect was observed across the groups (both>either>neither). Compared to those in the neither group men categorized as both or either reported more frequent urological chronic pelvic pain syndrome symptom flares, catastrophizing and irritable bowel syndrome, and women categorized as both or either were more likely to have a negative affect and chronic fatigue syndrome. CONCLUSIONS Men and women with bladder symptoms characterized as painful filling or painful urgency had more severe urological symptoms, more generalized symptoms and worse quality of life than participants who reported neither characteristic, suggesting that these symptom characteristics might represent important subsets of patients with urological chronic pelvic pain syndromes.

Abstract
Background The “Multidisciplinary Approach to the Study of Chronic Pelvic Pain” (MAPP) Research Network was established by the NIDDK to better understand the pathophysiology of urologic chronic pelvic pain syndromes (UCPPS), to inform future clinical trials and improve clinical care. The evolution, organization, and scientific scope of the MAPP Research Network, and the unique approach of the network’s central study and common data elements are described. Methods The primary scientific protocol for the Trans-MAPP Epidemiology/Phenotyping (EP) Study comprises a multi-site, longitudinal observational study, including bi-weekly internet-based symptom assessments, following a comprehensive in-clinic deep-phenotyping array of urological symptoms, non-urological symptoms and psychosocial factors to evaluate men and women with UCPPS. Healthy controls, matched on sex and age, as well as “positive” controls meeting the non-urologic associated syndromes (NUAS) criteria for one or more of the target conditions of Fibromyalgia (FM), Chronic Fatigue Syndrome (CFS) or Irritable Bowel Syndrome (IBS), were also evaluated. Additional, complementary studies addressing diverse hypotheses are integrated into the Trans-MAPP EP Study to provide a systemic characterization of study participants, including biomarker discovery studies of infectious agents, quantitative sensory testing, and structural and resting state neuroimaging and functional neurobiology studies. A highly novel effort to develop and assess clinically relevant animal models of UCPPS was also undertaken to allow improved translation between clinical and mechanistic studies. Recruitment into the central study occurred at six Discovery Sites in the United States, resulting in a total of 1,039 enrolled participants, exceeding the original targets. The biospecimen collection rate at baseline visits reached nearly 100%, and 279 participants underwent common neuroimaging through a standardized protocol. An extended follow-up study for 161 of the UCPPS participants is ongoing. Discussion The MAPP Research Network represents a novel, comprehensive approach to the study of UCPPS, as well as other concomitant NUAS. Findings are expected to provide significant advances in understanding UCPPS pathophysiology that will ultimately inform future clinical trials and lead to improvements in patient care. Furthermore, the structure and methodologies developed by the MAPP Network provide the foundation upon which future studies of other urologic or non-urologic disorders can be based.

Abstract
UNLABELLED Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Penetrating trauma to the scrotum often requires operative intervention, with testicular salvage only possible when enough testicular tissue can be re-approximated in the traumatic setting. The present report represents the largest series of gunshot wound trauma to the scrotum in the literature. Further, it validates recommendations of the European Association of Urology guidelines on urological trauma that advocate operative intervention due to minimal rates of patient morbidity and the inherent limitations of scrotal ultrasonography in discerning testicular compromise. OBJECTIVE To report our 20-year experience of gunshot wounds (GSWs) to the scrotum and outline the management of this traumatic injury. PATIENTS AND METHODS We queried our institutional database for patients presenting with GSWs to the scrotum between 1985 and 2006. All patients underwent the standard trauma evaluation upon presentation, including physical examination of the external genitalia. Management was dictated by the presence or absence of a penetrating injury to the scrotum and associated traumatic injuries. Nonoperative and operative management of traumatic injury to the scrotum were used. Testicular salvage was performed when anatomically feasible. If testicular salvage was not feasible, an orchiectomy was performed. RESULTS Scrotal exploration was performed in 91 (94%) patients while six (6%) patients were treated nonoperatively. Testicular injury was found in 44 (48%) patients undergoing exploration, six (7%) of whom had bilateral testicular injuries, which gave a total of 50 injured testicles. Of the injured testicles, 24 (48%) could not be salvaged and required orchiectomy, while 26 (52%) were debrided and repaired. The most common associated genitourinary (GU) injuries were to the corpora cavernosum (n= 20 [21%]) and urethra (n= 10 [10%]). Soft tissue injury of the extremities occurred in 54 patients (56%), representing the most common non-GU-associated injury. Postoperative complications occurred infrequently: one patient (1%) returned for abscess drainage and one (1%) for haematoma evacuation. CONCLUSIONS The present report confirms that any patient with a penetrating injury to the scrotum should undergo immediate scrotal exploration. A low clinical suspicion for performing additional studies to rule out associated urethral and/or penile injury is clinically warranted. Testicular loss occurs in ≈50% of injured testicles.

Abstract
OBJECT Nerve transfers are an effective means of restoring control to paralyzed somatic muscle groups and, recently, even denervated detrusor muscle. The authors performed a cadaveric pilot project to examine the feasibility of restoring control to the urethral and anal sphincters using a femoral motor nerve branch to reinnervate the pudendal nerve through a perineal approach. METHODS Eleven cadavers were dissected bilaterally to expose the pudendal and femoral nerve branches. Pertinent landmarks and distances that could be used to locate these nerves were assessed and measured, as were nerve cross-sectional areas. RESULTS A long motor branch of the femoral nerve was followed into the distal vastus medialis muscle for a distance of 17.4 ± 0.8 cm, split off from the main femoral nerve trunk, and transferred medially and superiorly to the pudendal nerve in the Alcock canal, a distance of 13.7 ± 0.71 cm. This was performed via a perineal approach. The cross-sectional area of the pudendal nerve was 5.64 ± 0.49 mm(2), and the femoral nerve motor branch at the suggested transection site was 4.40 ± 0.41 mm(2). CONCLUSIONS The use of a femoral nerve motor branch to the vastus medialis muscle for heterotopic nerve transfer to the pudendal nerve is surgically feasible, based on anatomical location and cross-sectional areas.

Abstract
BACKGROUND Evidence suggests that the urogenital pain of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) may be neuropathic. METHODS This randomized, double-blind, placebo-controlled trial was conducted across 10 tertiary care centers in North America to determine whether pregabalin, which has been proved effective in other chronic pain syndromes, is effective in reducing CP/CPPS symptoms. In 2006-2007, 324 men with pelvic pain for at least 3 of the previous 6 months were enrolled in this study. Men were randomly assigned to receive pregabalin or placebo in a 2:1 ratio and were treated for 6 weeks. Pregabalin dosage was increased from 150 to 600 mg/d during the first 4 weeks. The primary outcome was a 6-point decrease in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score. Multiple secondary outcomes were assessed. RESULTS Of 218 men assigned to receive pregabalin, 103 (47.2%) reported at least a 6-point decrease in the NIH-CPSI total score at 6 weeks compared with 35.8% (38 of 106 men) assigned to receive placebo (P = .07, exact Mantel-Haenszel test, adjusting for clinical sites). Compared with the placebo group, men assigned to receive pregabalin experienced reductions in the NIH-CPSI total score and subscores (P < .05), a higher Global Response Assessment response rate (31.2% and 18.9%; P = .02), and improvement in total McGill Pain Questionnaire score (P = .01). Results for the other outcomes did not differ between groups. CONCLUSION Pregabalin therapy for 6 weeks was not superior to placebo use in the rate of a 6-point decrease (improvement) in the NIH-CPSI total score in men with CP/CPPS.

Abstract
PURPOSE Anticholinergic medications are commonly used to treat urinary urgency and frequency. Muscarinic receptors are located in areas beyond the detrusor muscle. In this study we measured changes in central nervous system activity in patients with lower urinary tract symptoms treated with tolterodine or a placebo. MATERIALS AND METHODS A total of 20 female patients with urinary frequency were randomized to 4 weeks of treatment with tolterodine or a placebo. Functional magnetic resonance imaging based on blood oxygenation level dependant imaging of the brain during bladder filling was performed before and after treatment. For each patient the bladder was filled by a urethral catheter and emptied 5 times. RESULTS Multiple brain areas showed significant activation with bladder filling compared to the empty state and many areas also showed deactivation. Overall brain activation with bladder filling was decreased after treatment in both groups. After treatment 2 areas of the parietal cortex (precuneus and postcentral gyrus) showed significantly greater activity in patients treated with tolterodine vs placebo. Two areas of the cerebellum (anterior lobe and culmen) showed significantly greater activity in the placebo group, and these were also areas of significant deactivation in the tolterodine group. CONCLUSIONS Brain activity changes as well as the areas of activation after treatment of lower urinary tract symptoms in patients with an anticholinergic medication or placebo are different in the 2 groups. Whether this finding represents action at the central nervous system or the bladder level is not known.

Abstract
The urologic chronic pain conditions such as chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis are syndromes whose evaluation and management are controversial. Part of the difficulty in diagnosis and therapy is the heterogeneity of etiologies and symptoms. We propose a six-domain phenotype, which can classify these patients clinically and can direct the selection of therapy in the most evidence based multimodal manner. The domains are urinary, psychosocial, organ specific, infection, neurologic and tenderness of skeletal muscles. This system is flexible and responsive to new biomarkers and therapies as their utility and efficacy are proven.

Abstract
PURPOSE We reviewed the current literature on mechanisms involved in the pathogenesis of prostatitis/chronic pelvic pain syndrome (CPPS). MATERIALS AND METHODS A literature review for the years 1966 to 2003 was performed using the MEDLINE database of the United States National Library of Medicine. RESULTS National Institutes of Health categories I and II prostatitis result from identifiable prostatic infections, whereas patients with category IV are asymptomatic. The majority of symptomatic cases are category III or chronic prostatitis (CP)/CPPS. The etiology of CP/CPPS is unknown. The traditional marker of inflammation, namely white blood cells in prostatic fluids, does not correlate with the predominant symptom of pelvic pain. An imbalance toward increased proinflammatory and decreased anti-inflammatory cytokines has been implicated and a few studies have shown some correlation of this with pelvic pain. The imbalance in some men may result from polymorphisms at the cytokine loci. An autoimmune process may be involved and experimental evidence indicates that this can be under hormonal influence. Recent findings include possible defects in the androgen receptor. The prostate may not even be the source of the symptoms. Pelvic pain also correlates with the neurotrophin nerve growth factor implicated in neurogenic inflammation and central sensitization. Finally, psychological stress may produce measurable biochemical changes and influence the other processes. The role of normal prostatic bacterial flora in inciting the inflammatory response has also been reconsidered. CONCLUSIONS The symptoms of CP/CPPS appear to result from an interplay between psychological factors and dysfunction in the immune, neurological and endocrine systems.

Abstract
BACKGROUND Prostatitis accounts for 2 million outpatient visits annually. The majority of prostatitis cases fit the definition of chronic pelvic pain syndrome, for which routine antibiotic use is not indicated. METHODS Inpatient, outpatient, and pharmacy datasets from the Veterans Health Administration were used to quantify the magnitude of antibiotic use attributable to chronic pelvic pain syndrome. Specifically, men with a diagnosis of infectious/acute prostatitis or a urinary tract infection were excluded, and the remaining men with a diagnosis of prostatitis were defined as having chronic pelvic pain syndrome. RESULTS The annual prevalence of chronic pelvic pain syndrome was 0.5%. Prescriptions for fluoroquinolone antibiotics were filled in 49% of men with a diagnosis of chronic pelvic pain syndrome compared with 5% in men without chronic pelvic pain syndrome. Men with chronic pelvic pain syndrome were more than 7 times more likely to receive a fluoroquinolone prescription independently of age, race/ethnicity, and comorbid conditions. Increased use of other antibiotics also was observed. High use was similar in men with either infectious/acute prostatitis or chronic pelvic pain syndrome. CONCLUSION Despite evidence that antibiotics are not effective in the majority of men with chronic pelvic pain syndrome, they were prescribed in 69% of men with this diagnosis. Some increased use is probably due to uncontrolled confounding by comorbid conditions or inaccurate diagnostic coding. However, a 7-fold higher rate of fluoroquinolone usage suggests that strategies to reduce unnecessary antibiotic use in men with prostatitis are warranted.

Abstract
OBJECTIVE To examine interactions between demographic, pain, urinary, psychological and environmental predictors of quality of life (QOL) in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). PATIENTS AND METHODS In all, 253 men previously enrolled in the National Institutes of Health Chronic Prostatitis Cohort study in North American tertiary-care clinical centres (six in the USA and one in Canada) self-reported with validated instruments, including the QOL subscales of the Short Form-12 (physical, SF12-PCS; and mental, SF12-MCS), demographics, urinary symptoms, depression, current pain, pain coping, 'catastrophizing' (catastrophic thinking about pain), pain control, social support and solicitous responses from a partner. Data were collected through a one-time survey. Covariates determined to be significant were entered into a multivariable regression model predicting SF12-PCS and SF12-MCS. RESULTS Adjusting for covariates, regression models showed that poorer SF12-PCS scores were predicted by worse urinary function (P < 0.001) and increased use of pain-contingent resting as a coping strategy (P = 0.026). Further, poorer SF12-MCS scores were predicted by greater pain catastrophizing (P = 0.002) and lower perceptions of social support (P< 0.001). In separate follow-up analyses, helplessness was the significant catastrophizing subscale (P < 0.001), while support from family and friends were the significant social support subscales (P = 0.002 and <0.001). CONCLUSIONS These data suggest that specific coping and environmental factors (i.e. catastrophizing, pain-contingent resting, social support) are significant in understanding how patients with CP/CPPS adjust. These data can be used to develop specific cognitive-behavioural programmes for men with CP/CPPS who are refractory to standard medical therapy.

Abstract
PURPOSE We quantified the burden of prostatitis in the United States by identifying trends in the use of health care resources and estimating the economic impact of the disease. MATERIALS AND METHODS The analytical methods used to generate these results were described previously. RESULTS The rate of national inpatient hospitalizations for a diagnosis of prostatitis decreased by 21% between 1994 and 2000. Hospitalization rates were 2 to 2.5 times higher for Medicare beneficiaries with a 42% decrease between 1992 and 2001. Combined physician outpatient and hospital outpatient visits revealed an age adjusted, annualized visit rate for prostatitis of 1,798/100,000 population. More than 6% of visits with a primary diagnosis of prostatitis had a concomitant diagnosis of benign prostatic hyperplasia. The most common medications associated with any visits for prostatitis were quinolones (annualized rate 319/100,000 population) and the rate remained about the same even after visits for infectious prostatitis were removed from the data. The cost of prostatitis was about $84 million annually, exclusive of pharmaceutical spending. Of 897 privately insured men with a medical claim for prostatitis in 2002, 14% missed some work because of the condition. CONCLUSIONS Overall spending in the United States for the diagnosis and management of prostatitis, exclusive of pharmaceutical spending, totaled $84 million in 2000 and it appears to be increasing with time. Given the extensive gaps in our understanding of the diagnosis of and treatment for prostatitis, many of these expenditures may represent a waste of resources.

Abstract
UNLABELLED Cognitive/behavioral and environmental variables are significant predictors of patient adjustment in chronic pain. Using a biopsychosocial template and selecting several pain-relevant constructs from physical, cognitive/behavioral, and environmental predictors, outcomes of pain and disability in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were explored. Men (n = 253) from a North American multi-institutional NIH-funded Chronic Prostatitis Cohort Study in 6 US and 1 Canadian centers participated in a survey examining pain and disability. Measures included demographics, urinary symptoms, depression, pain, disability, catastrophizing, control over pain, pain-contingent rest, social support, and solicitous responses from a significant other. Regressions showed that urinary symptoms (beta = .20), depression (beta = .24), and helplessness catastrophizing (beta = .29) predicted overall pain. Further, affective pain was predicted by depression (beta = .39) and helplessness catastrophizing (beta = .44), whereas sensory pain was predicted by urinary symptoms (beta = .25) and helplessness catastrophizing (beta = .37). With regard to disability, urinary symptoms (beta = .17), pain (beta = .21), and pain-contingent rest (beta = .33) were the predictors. These results suggest cognitive/behavioral variables (ie, catastrophizing, pain-contingent rest) may have significant impact on patient adjustment in CP/CPPS. Findings support the need for greater research of such pain-related variables in CP/CPPS. PERSPECTIVE This article explores predictors of patient adjustment in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Cognitive/behavioral variables of catastrophizing and pain-contingent rest respectively predicted greater pain and disability. Catastrophic helplessness was a prominent pain predictor. These findings inform clinicians and researchers on several new variables in CP/CPPS outcomes and suggest future research.

Abstract
The goal of this study was to transect and immediately repair ventral roots, selected by their ability to stimulate bladder contraction, to assess the feasibility of bladder reinnervation in a canine model. Brain-derived neurotrophic factor (BDNF) was delivered via an osmotic pump (0.5 or 5 mg/mL) to a cuff surrounding the reanastomosis site to the two root bundles on one side. Electrodes were implanted bilaterally immediately proximal to the site of surgical reanastomosis. Results were compared to four root-intact, control animals that also received bilateral electrode implantation. At 6-12 months post-surgery, five of eight nerve transected and repaired animals showed increased pressure and bladder emptying during electrical stimulation of the repaired ventral roots contralateral to the BDNF delivery side. Nerve tracing studies one year postoperatively determined the repaired roots to be S1 and S2 and showed regrowth of axons from the spinal cord to nerve sites proximal to the repair site and to the bladder, and the presence of neurofilament-labeled axons growing across the ventral root repair site. In conclusion, transected ventral and dorsal roots in the sacral spine can be repaired and are capable of functionally reinnervating the urinary bladder. This feasibility study paves the way for future studies utilizing other more proximal motor nerves to bypass the transection site for bladder reinnervation.

Abstract
Interstitial cystitis and chronic prostatitis/chronic pelvic pain syndrome are clinical syndromes characterized by pelvic pain with or without voiding symptoms such as urgency and frequency. There are many similarities in their epidemiology, adverse effect on quality of life, etiology/pathophysiology, natural history, and response to similar treatments. However, overlapping clinical definitions and similar entrance criteria for large-scale cohort studies make comparisons problematic. Newer efforts to classify pelvic pain syndromes should help in our recognition that interstitial cystitis and chronic prostatitis/chronic pelvic pain syndrome likely are not organ-specific syndromes but urogenital manifestations of regional or systemic abnormalities.

Abstract
PURPOSE The Meares-Stamey 4-glass test is the standard method of assessing inflammation and the presence of bacteria in the lower urinary tract in men presenting with the chronic prostatitis syndrome. However, most urologists do not use it in daily practice because of the time and difficulty in performing it, as well as the additional expense. We evaluated a simpler test, the 2-glass pre-massage and post-massage test, and compared it with the Meares-Stamey 4-glass test to detect inflammation and bacteria in men with chronic prostatitis/chronic pelvic pain syndrome. MATERIALS AND METHODS The study population included 353 men enrolled in the National Institutes of Health Chronic Prostatitis Cohort study with baseline leukocyte counts and 2-day bacterial cultures on specimens obtained from a standard 4-glass test (VB1, VB2, expressed prostatic secretions, VB3). The chi-square test was performed to assess associations of white blood cell counts in expressed prostatic secretions and VB3. A receiver operating characteristic curve was constructed to determine the optimal cut point of white blood cells in VB3 in predicting white blood cells in expressed prostatic secretions. Sensitivity and specificity of VB3 cultures predicting expressed prostatic secretions and positive Meares-Stamey results were calculated from 2 x 2 contingency tables. RESULTS Analysis of binary leukocyte outcomes (no white blood cells vs any white blood cells) suggests that white blood cells tend to be present in expressed prostatic secretions when there are any white blood cells in VB3, p <0.0001, the optimal cut point being white blood cell counts of 3 in VB3 (best predictive ability with area under ROC 0.771) to predict 5+ in expressed prostatic secretions with a sensitivity of 76% and specificity of 70%. The optimal cut point of white blood cells in VB3 to predict 10 white blood cells in expressed prostatic secretions was 4 (62% sensitivity and 75% specificity). Uropathogens localizing to expressed prostatic secretions or VB3 confirms a positive 4-glass Meares-Stamey localization test. The sensitivity and specificity of a VB3 localizing culture only in predicting a positive Meares-Stamey 4-glass test result for any uropathogen were 44% to 54% (depending on definition) and 100%, respectively. The pre-massage and post-massage test predicted a correct diagnosis in more than 96% of subjects. CONCLUSIONS The value of localizing leukocytes and uropathogens to prostate specific specimens remains controversial in chronic heavily pretreated patients, but these data may help direct therapy (anti-inflammatory or antimicrobial) when obtained at first presentation. The pre-massage and post-massage test has strong concordance with the 4-glass test and is a reasonable alternative when expressed prostatic secretions are not obtained.

Abstract
STUDY DESIGN Postintervention. OBJECTIVES To determine the effectiveness of the Praxis multifunctional implantable functional electrical stimulation (FES) system (Neopraxis Pty. Ltd, Lane Cove, NSW, Australia) to provide standing and stepping ability and bladder and bowel management for individuals with motor complete thoracic level spinal cord injuries (SCI). SETTING Pediatric orthopedic hospital specializing in SCI. SUBJECTS Three males, ages 17 and 21 years, with motor-complete thoracic level SCI and intact lower motor neurons to the muscles targeted for stimulation. METHODS Each subject was successfully implanted with the Praxis FES system. All three subjects received electrodes for upright mobility and the first two subjects received additional electrodes for stimulated bladder and bowel management. Following training, subjects were evaluated in their ability to use FES for nine mobility activities. Acute and chronic experiments of the effect of stimulation on bowel and bladder function were also performed. RESULTS All three subjects could independently stand up from the wheelchair and could walk at least 6 m using a swing through gait pattern. Two subjects were able to independently perform swing through gait for 6 min and one subject was able to independently ascend and descend stairs. Suppression of reflex bladder contractions by neuromodulation (subject 1) and stimulated contractions of the rectum (subject 2) were observed in acute experiments. When stimulation was applied over the course of several weeks, a positive effect on bowel function was measured. Stimulated bladder contractions were not achieved. CONCLUSION The feasibility of using the Praxis FES system for upright mobility and aiding aspects of bladder and bowel function was demonstrated with three subjects with thoracic level SCI.

Abstract
PURPOSE We provide an overview of the medical literature supporting the combined use of muscarinic and alpha-adrenergic antagonist therapy for the treatment of voiding dysfunction. MATERIALS AND METHODS The MEDLINE database (1966 to 2004) of the United States National Library of Medicine was searched for pertinent studies. RESULTS Although the mechanism of action of alpha-adrenergic antagonist therapy for voiding dysfunction has traditionally been assumed to be relaxation of the periurethral, prostatic and bladder neck smooth muscle, substantial evidence supports action at extraprostatic sites involved in micturition, including the bladder dome smooth muscle, peripheral ganglia, spinal cord and brain. Likewise the mechanism of action of anticholinergic therapy has been traditionally assumed to be inhibition of the M3 muscarinic receptor subtypes that mediate normal bladder contractions. However, M2 receptor mediates hypertrophied bladder contractions and there is evidence for an M2 component to the suprasacral control of voiding. CONCLUSIONS Based on the physiology of alpha-adrenergic and muscarinic receptors the inhibition of each one would be expected to be more beneficial than that of either alone because they would work on 2 components of detrusor function. Patients who would likely benefit from this combination therapy are men with lower urinary tract symptoms, women with urgency/frequency syndrome (overactive bladder), patients with uninhibited bladder contractions due to neurogenic bladder, and patients with pelvic pain and voiding symptoms, ie interstitial cystitis and chronic prostatitis/chronic pelvic pain syndrome.

Abstract
OBJECTIVE To compare the demographic, behavioural, clinical and medical history characteristics of men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and asymptomatic controls, to identify characteristics that might be associated with this syndrome. PATIENTS AND METHODS Self-administered epidemiological questionnaires were completed by 463 men with CP/CPPS and 121 asymptomatic age-matched controls. We compared the prevalence of possible risk factors between men with CP/CPPS and controls, using generalized Mantel-Haenszel tests, and developed multivariate predictive models using logistic regression methods, adjusting for clustering by clinical centre within both methods. RESULTS Compared to controls, men with CP/CPPS reported a significantly greater lifetime prevalence of nonspecific urethritis (12% vs 4%, P = 0.008), cardiovascular disease (11% vs 2%, P = 0.004), neurological disease (41% vs 14%, P < 0.001), psychiatric conditions (29% vs 11%, P < 0.001), and haematopoietic, lymphatic or infectious disease (41% vs 20%, P < 0.001). CONCLUSION A wide range of self-reported medical conditions was associated with CP/CPPS. Further studies are necessary to determine whether they play a role in the pathogenesis of CP/CPPS.

Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men is principally defined by pain in the pelvic region lasting more than 3 months. No cause of the disease has been established, and therapies are empirical and mostly untested. Antimicrobial agents and alpha-adrenergic receptor blockers are frequently used. OBJECTIVE To determine whether 6-week therapy with ciprofloxacin or tamsulosin is more effective than placebo at improving symptoms in men with refractory, long-standing CP/CPPS. DESIGN Randomized, double-blind trial with a 2 x 2 factorial design comparing 6 weeks of therapy with ciprofloxacin, tamsulosin, both drugs, or placebo. SETTING Urology outpatient clinics at 10 tertiary care medical centers in North America. PATIENTS Patients were identified from referral-based practices of urologists. One hundred ninety-six men with a National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score of at least 15 and a mean of 6.2 years of symptoms were enrolled. Patients had received substantial previous treatment. MEASUREMENTS The authors evaluated NIH-CPSI total score and subscores, patient-reported global response assessment, a generic measure of quality of life, and adverse events. INTERVENTIONS Ciprofloxacin, 500 mg twice daily; tamsulosin, 0.4 mg once daily; a combination of the 2 drugs; or placebo. RESULTS The NIH-CPSI total score decreased modestly in all treatment groups. No statistically significant difference in the primary outcome was seen for ciprofloxacin versus no ciprofloxacin (P = 0.15) or tamsulosin versus no tamsulosin (P > 0.2). Treatments also did not differ significantly for any of the secondary outcomes. LIMITATIONS Treatment lasting longer than 6 weeks was not tested. Patients who had received less pretreatment may have responded differently. CONCLUSION Ciprofloxacin and tamsulosin did not substantially reduce symptoms in men with long-standing CP/CPPS who had at least moderate symptoms.

Abstract
PURPOSE We reviewed the current literature on mechanisms involved in the pathogenesis of prostatitis/chronic pelvic pain syndrome (CPPS). MATERIALS AND METHODS A literature review for the years 1966 to 2003 was performed using the MEDLINE database of the United States National Library of Medicine. RESULTS National Institutes of Health categories I and II prostatitis result from identifiable prostatic infections, whereas patients with category IV are asymptomatic. The majority of symptomatic cases are category III or chronic prostatitis (CP)/CPPS. The etiology of CP/CPPS is unknown. The traditional marker of inflammation, namely white blood cells in prostatic fluids, does not correlate with the predominant symptom of pelvic pain. An imbalance toward increased proinflammatory and decreased anti-inflammatory cytokines has been implicated and a few studies have shown some correlation of this with pelvic pain. The imbalance in some men may result from polymorphisms at the cytokine loci. An autoimmune process may be involved and experimental evidence indicates that this can be under hormonal influence. Recent findings include possible defects in the androgen receptor. The prostate may not even be the source of the symptoms. Pelvic pain also correlates with the neurotrophin nerve growth factor implicated in neurogenic inflammation and central sensitization. Finally, psychological stress may produce measurable biochemical changes and influence the other processes. The role of normal prostatic bacterial flora in inciting the inflammatory response has also been reconsidered. CONCLUSIONS The symptoms of CP/CPPS appear to result from an interplay between psychological factors and dysfunction in the immune, neurological and endocrine systems.

Abstract
BACKGROUND Little information exists on the economic impact of chronic prostatitis. The objective of this study was to determine the direct and indirect costs associated with chronic prostatitis. METHODS Outcomes were assessed using a questionnaire designed to capture health care resource utilization. Resource estimates were converted into unit costs with direct medical cost estimates based on hospital cost-accounting data and indirect costs based on modified labor force, employment, and earnings data from the US Census Bureau. RESULTS The total direct costs for the 3 months prior to entry into the cohort, excluding hospitalization, were $126 915 for the 167 study participants for an average of $954 per person among the 133 consumers. Of the men, 26% reported work loss valued at an average of $551. The average total costs (direct and indirect) for the 3 months was $1099 per person for those 137 men who had resource consumption with an expected annual total cost per person of $4397. For those study participants with any incurred costs, tests for association revealed that the National Institutes of Health Chronic Prostatitis Symptom Index (P<.001) and each of the 3 subcategories of pain (P =.003), urinary function (P =.03), and quality-of-life (P =.002) were significantly associated with resource use, although the quality-of-life subscale score from the National Institutes of Health Chronic Prostatitis Symptom Index was the only predictor of resource consumption. CONCLUSIONS Chronic prostatitis is associated with substantial costs and lower quality-of-life scores, which predicted resource consumption. The economic impact of chronic prostatitis warrants increased medical attention and resources to identify and test effective treatment strategies.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common of the prostatitis syndromes. It is characterised by pelvic pain, with or without voiding symptoms. CP/CPPS accounts for 2 million office visits in the US alone. Recent epidemiological studies have shown that CP/CPPS can affect men at any age, including those in their 80s. The aetiology is unknown but proposals include infectious, autoimmune, neurologic and psychiatric causes. Men with CP/CPPS are much more likely to have had a past medical history of cardiovascular, neurologic, psychiatric or infectious disease (particularly sinusitis) as compared with asymptomatic individuals. Although leucocytes are commonly found in the prostatic fluid of these men, they do not correlate with the symptoms. The clinical evaluation now includes a validated, self administered symptom score, the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), which was designed as an outcome measure for treatment trials. This can aid in diagnosis and follow-up of patients' response to therapy. Treatment for CP/CPPS is empiric and limited by a lack of randomised, placebo-controlled clinical trials. Antimicrobials are commonly used to treat the symptoms of CP/CPPS. However, the finding that asymptomatic men have equal or greater numbers of bacteria which localise to the prostatic fluid, compared with men with CP/CPPS, has raised doubts about the contribution of infection to the symptoms. Other commonly used drugs include alpha-adrenoceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents. The adverse effects of these medications are a concern in older men with CP/CPPS. Other therapies available include minimally invasive procedures such as microwave thermotherapy and transurethral needle ablation, and now neuromodulation devices.Although much progress has been made, particularly in the last 7 years, considerable work still remains to be done to determine the aetiology and pathogenesis of CP/CPPS, and to develop mechanism based therapy that is shown to be effective in controlled trials.
