    ABSTRACT: PURPOSE: This systematic review focuses on the relationship between nocturia and depression/anxiety. Our objective is to provide an overview of current data regarding the epidemiology, pathophysiology, and patient management implications of the association between nocturia and depression/anxiety. MATERIALS AND METHODS: Pubmed, Web of Science, and Embase were queried in July 2012 to identify abstracts, original, review and editorial articles on nocturia and mood disorders, specifically depression and anxiety. The search was conducted using the following keywords: "nocturia", "depression", and "anxiety". We complied with the Assessment of Multiple Systemic Reviews instrument. We retrieved a total of 500 records with 95, 81, and 324 from Pubmed, Web of Science, and Embase, respectively. RESULTS: Cross sectional (level 3) data indicate that nocturia and depression/anxiety are strongly associated. One prospective study contends that depression leads to nocturia in a unidirectional relationship. Nocturia poses a greater risk for depression in men versus women. Results are conflicting regarding the effect of SSRI's on nocturia. CONCLUSIONS: The results of this systematic review suggest a bidirectional association between depression and nocturia. The relationship between anxiety and noctuira is less clear. Practicing clinicians should consider administering a brief self-administered scale to assess for depression in nocturia patients.

    ABSTRACT: AIMS: To determine whether cavernous nerve injury (CNI) alters lower urinary tract function, we assessed bladder and urethral function over time in a mouse model of CNI. METHODS: Twelve-week-old male C57BL/6 mice were divided into three groups: unoperated (UO; n = 6), sham-operated (SO; n = 18), and bilateral CNI (n = 30) group. At 1, 2, 4, 6, 8, 10 days bladder and urethral function were evaluated in these three groups using cystometry (CMG) and leak point pressure (LPP) recording under anesthesia. RESULTS: There was no significant difference in maximum detrusor pressure between groups at all times. Compared with the UO group, bladder compliance, and capacity in the CNI group were significantly decreased at Days 1, 2, 4 (P < 0.05) and recovered gradually from Day 6 to Day 10. In the SO group, they were decreased at Day 1, however, recovered more rapidly than the CNI group. Non-voiding contractions (NVC) developed in the CNI group at all times. Intercontraction interval were significantly decreased in SO and CNI groups and recovered more rapidly in SO group. In the SO group NVC were observed only at Days 1 and 2. LPP in the CNI group was decreased significantly at Days 1 and 2 (P < 0.05) and rapidly recovered with time compared with the UO and SO groups. CONCLUSION: In a mouse model of CNI, a transient decrease in bladder compliance, capacity, LPP and increased NVC was observed. These changes gradually recovered from Day 6 after CNI. Our findings suggest that CNI may affect bladder and urethral function, but alterations are reversible. Neurourol. Urodynam. © 2012 Wiley Periodicals, Inc.

    ABSTRACT: Introduction.  Diabetes mellitus (DM) is a major risk factor for developing erectile dysfunction (ED) and men with DM are often less responsive to phosphodiesterase type 5 (PDE5) inhibitors than ED due to other causes. Aims.  The aim of this study was to explore potential mechanisms whereby PDE5 inhibitors may have reduced efficacy in type 2 DM. Methods.  At 4 weeks of age, mice were either fed a high-fat diet (HFD) for 22-36 weeks or fed regular chow (control). An additional group of mice in the same genetic background had a genetic form of type 1 DM. Main Outcome Measures.  Glucose tolerance testing, intracorporal pressures (ICPs), oxidative stress (OS), apoptotic cell death (active caspase-3 and apostain), PDE5, p53, and cyclic guanosine monophosphate (cGMP) levels, and histological examination of inflow arteries were performed in mice fed a HFD and control mice. A group of mice with type 1 DM were studied for PDE5 expression levels. Results.  All mice fed a HFD had impaired glucose tolerance compared with the age-matched mice fed on standard chow diet (control). HFD fed mice had reduced maximum ICPs following in vivo cavernous nerve electrical stimulation and increased apoptotic cell death, OS, and p53 levels in the corporal tissue. Interestingly, PDE5 levels were increased and cGMP levels were decreased. In contrast, mice with type 1 DM did not have increases in PDE5. Conclusions.  Taken together, our results suggest that type 2 DM-induced ED is associated with findings that could lead to reduced cGMP and may account for reduced efficacy of PDE5 inhibitors.

    ABSTRACT: We examined the association between the use of medications and the prevalence of urinary incontinence in gender specific analyses of a community based, representative sample. A population based epidemiological study was conducted of 5,503 men and women 30 to 79 years old residing in Boston, Massachusetts (baseline data collected from 2002 to 2005). Urological symptoms were ascertained in a 2-hour, in person interview. Urinary incontinence was defined as urine leakage occurring weekly or more often during the last year. Medications used in the last month were considered current use. Associations of 20+ medications and prevalent urinary incontinence were examined using multivariate logistic regression (ORs and 95% CIs) with adjustments for known urinary incontinence risk factors. The prevalence of urinary incontinence in the analysis sample was 9.0% in women and 4.6% in men. For women the prevalence was highest among users of certain antihistamines (28.4%) and angiotensin II receptor blockers (22.9%). For men the prevalence was highest among angiotensin II receptor blocker (22.2%) and loop diuretic (19.1%) users. After final multivariate adjustment there were significant positive associations for certain antihistamines, beta receptor agonists, angiotensin II receptor blockers and estrogens with urinary incontinence in women (all ORs greater than 1.7), and a borderline significant association for anticonvulsants (OR 1.75; 95% CI 1.00, 3.07). Among men only anticonvulsants were associated with urinary incontinence after final adjustments (OR 2.50; 95% CI 1.24, 5.03), although angiotensin II receptor blockers showed an adjusted association of borderline significance (OR 2.21; 95% CI 0.96, 5.10). Although a cross-sectional analysis cannot determine causality, our analysis suggests certain medications should be further examined in longitudinal analyses of risk to determine their influence on urological symptoms.

    ABSTRACT: Microdissection testicular sperm extraction markedly improves the sperm retrieval rates in men with nonobstructive azoospermia. However, localizing sperm foci can be time-consuming and it is not always successful. Fiberoptic confocal fluorescent microscopy offers the advantage of rapid in vivo detection of fluorescently labeled sperm in the seminiferous tubules. After establishing the feasibility of fiberoptic confocal fluorescent microscopy to identify antibody labeled sperm in vivo C57/B6 mice underwent intraperitoneal injection of busulfan to induce azoospermia. During spermatogenesis reestablishment at approximately 16 weeks the mice were anesthetized and the testes were delivered through a low midline incision. Fluorescein isothiocyanate labeled antibody to intra-acrosomal protein Hs-14 was injected retrograde into a single murine rete testis. The testes were imaged in vivo with fiberoptic confocal fluorescent microscopy and sperm foci were detected. The respective seminiferous tubules were excised and squash prepared for immunofluorescence microscopy. Sperm foci were identified in the testis injected with fluorescently tagged antibody by in vivo fiberoptic confocal fluorescence microscopy. The contralateral control testis of each mouse showed no specific signal. Immunofluorescence microscopy of the excised tubules provided morphological confirmation of the presence of labeled sperm with an absence in controls. Findings were consistent in the feasibility portion of the study and in the busulfan model of nonobstructive azoospermia. Fiberoptic confocal fluorescent microscopy was feasible during microdissection testicular sperm extraction in an azoospermic mouse model to identify fluorescently labeled sperm in vivo. Translation to the clinical setting could decrease operative time and improve the sperm harvest rate.

    ABSTRACT: Lower urinary tract symptoms (LUTS) such as urinary frequency and urgency are bothersome and associated with reduced quality of life. Atypical antipsychotics (AAPs) have been implicated in increasing the risk of urinary incontinence. In a large community-based sample of men and women, we examined the associations of AAP and selective serotonin reuptake inhibitor (SSRIs) use with LUTS. Data were collected (2002-2005) from a generalizable sample of Boston, MA, USA, residents aged 30-79 (N = 5503). LUTS were assessed using the American Urologic Association Symptom Index (AUA-SI). The prevalence of clinically-significant LUTS was estimated using a cutoff AUA-SI score of 8+ to indicate moderate-to-severe symptoms. Confounder-adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated from multivariate logistic regression to estimate the associations for psychoactive drugs used in the previous month (SSRIs, AAPs, both) and LUTS. Among women, AAP users had a higher prevalence of LUTS (46.2%) compared with SSRI users (23.5%) and those with depressive symptoms not using SSRIs or AAPs (26.3%). Corresponding prevalence estimates among men were 32.7%, 29.8%, and 33.3%. In multivariate models, AAP use was significantly associated with LUTS among women when used either with (OR = 2.72, 95% CI:1.45-5.10) or without (OR = 3.05, 95% CI:1.30-7.16) SSRIs, but SSRI use without AAP use was not associated with LUTS compared with nonusers without depressive symptoms. No associations were observed among men. In our study, AAPs but not SSRIs were associated with increased prevalence of LUTS among women only. Further prospective research is needed to determine time sequence and cause and effect.

    ABSTRACT: We examined the evaluation of and management for lower urinary tract symptoms/benign prostatic hyperplasia by physician specialty (urologist vs primary care physician). The BPH Registry and Patient Survey is a longitudinal, observational, disease registry cohort of patients enrolled from January 2004 to February 2005 in the United States. The survey examines patient outcomes and physician practice patterns in the management of lower urinary tract symptoms associated with clinical benign prostatic hyperplasia. It includes 402 urologist and primary care physician practices throughout the United States. Included in this study were 6,924 men with lower urinary tract symptoms/benign prostatic hyperplasia managed by watchful waiting or medical therapy. Data were collected on demographics, clinical characteristics and lower urinary tract symptoms/benign prostatic hyperplasia management using physician and patient completed forms. Multivariate analysis was done by physician specialty. Based on multivariate analysis urologists were more likely than primary care physicians to perform urinalysis (OR 3.9), serum prostate specific antigen (OR 1.2) and post-void residual urine (OR 18.9) measurement, uroflowmetry (OR 17.3), prostate ultrasound (OR 7.7) and biopsy (OR 3.5), renal ultrasound (OR 4.0) and cystoscopy (OR 4.6) but less likely to measure creatinine (OR 0.1). Men seeing urologists were twice as likely as men seeing primary care physicians to be treated with benign prostatic hyperplasia medical therapy vs watchful waiting. Significant differences by physician specialty were also observed for specific benign prostatic hyperplasia medical therapies. Significant differences in practice patterns were observed between primary care physicians and urologists in the evaluation of and management for lower urinary tract symptoms/benign prostatic hyperplasia. These data establish valuable benchmarks and identify possible interventions that may improve the standard of care.

    ABSTRACT: We assessed the need for academic urologists in 2010 and for the following 5 years. An 8-question survey was emailed to the 115 accredited academic urology residency programs recognized by the American Urological Association. Questions were related to the anticipated number of hires during the next 5 years, ideal minimum level of training, areas of expertise needed, current top need and allotted research time. Of 115 chairs or division heads 91 (79%) responded to the survey. Of all chairs 71% (65 of 91) expect to hire 2 to 4 physicians in the next 5 years. In total 91 chairs will be attempting to fill 292 openings. When carried out to 115 chairs, there will be 369 openings in the next 5 years (or 74 per year). The ideal minimum level of training was cited as clinical/research fellowship (37.1%), clinical fellowship (33.6%) and residency (10.5%). Areas of expertise needed most from each respective program include female urology/neurourology (51.7%), oncology (44.8%), and pediatrics and general urology (36.8%). The current top needs for respective programs include pediatrics 23.3%, female urology/neurourology 21.1% and oncology 18.9%. Of the chairs and division heads currently attempting to fill positions 53.5% have been searching for 2 or more years. There will be a tremendous need for academic urologists in the next 5 years. This need is thought to be due to an increased number of physicians retiring and decreased level of compensation compared to private practice.

    ABSTRACT: We investigate the association of different measures of adiposity (waist circumference, hip circumference, waist-to-hip ratio and body mass index) with overactive bladder (urinary frequency and urgency), whether the association varies by gender or age and whether it persists when models are adjusted for other confounders. Data were from the Boston Area Community Health epidemiological survey, a random sample of 5,503 Boston, Massachusetts, residents 30 to 79 years old with equal representation from 3 racial/ethnic groups (black, Hispanic and white). Statistical analysis involved nonparametric loess models and multivariate logistic regression. We noted distinct patterns by gender for the association of various adiposity measures with overactive bladder. Waist-to-hip ratio was not significantly associated with overactive bladder in either gender. In women the prevalence of overactive bladder increased as waist (OR adjusted for other confounders 1.10/10 cm increase) or hip circumference (OR 1.12/10 cm increase) or body mass index (OR 1.03/kg/m2 increase) increased. In men the prevalence of overactive bladder decreased as adiposity increased (OR 0.65/10 cm increase in waist circumference, OR 0.71/10 cm increase in hip circumference and OR 0.87/kg/m2 in body mass index) but only to a certain point (waist circumference 100 cm, hip circumference 115 cm and body mass index 27.5 kg/m2, respectively). At that point the prevalence of overactive bladder increased with increasing adiposity (OR 1.19/10 cm increase in waist circumference, OR 1.16/10 cm increase in hip circumference and OR 1.08/kg/m2 in body mass index). The relationship between adiposity and overactive bladder varies by gender.

    ABSTRACT: Statins may ameliorate lower urinary tract symptoms (LUTS) through anti-inflammatory or other pathways. We investigated the association between statin use and storage, voiding, and overall LUTS symptoms. The Boston Area Community Health Survey is an epidemiologic study of Boston, MA residents (2301 men; 3202 women) 30-79 years of age. LUTS, voiding, and storage symptoms were ascertained through an interviewer-administered questionnaire and defined as scores of greater than or equal to 8, greater than or equal to 5, and greater than or equal to 4, respectively, on relevant components of the American Urologic Association Symptom Index. Participants were included if they had a history of provider-diagnosed high cholesterol or recently used statin medications (n = 1346). Associations were estimated using odds ratios (ORs) and 95% confidence intervals (CI) from multivariate logistic regression. In multivariate models, statin use had no association with LUTS (OR= 1.03, 95% CI: 0.70, 1.51) among women. No associations were observed for any LUTS among younger (<60) men, but among older (60+) men, we observed significant inverse associations for voiding (OR= 0.23, 95% CI: 0.08, 0.66), storage (OR = 0.24, 95% CI: 0.11, 0.56), and overall LUTS (OR = 0.15, 95% CI: 0.05, 0.44). Our results suggest that use of statins is associated with a lower prevalence of urologic symptoms among older men but not among women or younger men.

    ABSTRACT: Patients with lesions of the central nervous system often have neurogenic bladder dysfunction. Lifelong bladder monitoring and management in these patients is necessary to prevent severe complications, including renal damage. The urodynamic test, performed by neurourologists or other specially trained providers, is the definitive test for diagnosis and management of neurogenic bladder dysfunction. This article describes the indications and technique of urodynamic testing and the interpretation of the results of such testing. The management of patients with neurogenic bladder dysfunction is also discussed.

    ABSTRACT: Autonomic innervation of urethral smooth muscle may influence urinary continence after prostatectomy. It is unclear whether the cavernous nerves carry fibers that influence continence. Using a retrograde axonal tracer combined with real-time in vivo imaging and ex vivo immunohistochemistry we determined the course and type of neurons supplying urethral smooth muscle distal to the prostate in the rat. We injected the retrograde axonal tracers cholera toxin B fragment-Alexa Fluor 488 and Fast Blue in the distal urethral smooth muscle in 10 rats each. Five days later the cavernous nerves and pelvic ganglion were imaged using fiberoptic confocal fluorescence microscopy (cholera toxin B fragment-Alexa Fluor 488) or harvested for immunohistochemistry (Fast Blue). Dual immunofluorescence of Fast Blue neurons with tyrosine hydroxylase or neuronal nitric oxide synthase was done to characterize neurons as noradrenergic or nitrergic. To ascertain whether the cavernous nerves contain fibers to the urethra that originate in the pelvic ganglia we cut the cavernous nerves with their ancillary branches in 3 rats and imaged them for Fast Blue. Fluorescent neurons and axons were detected in cavernous nerves and the pelvic ganglion. Few neurons were seen in rats with cavernous nerve section. Of urethral neurons 53.1% showed neuronal nitric oxide synthase positivity while 40.6% were immunoreactive for tyrosine hydroxylase. About 6.2% of urethral neurons failed to show tyrosine hydroxylase or neuronal nitric oxide synthase immunoreactivity. Most of the autonomic innervation to the urethra beyond the prostatic apex travels in the cavernous nerves. Many nerves may be parasympathetic based on neuronal nitric oxide synthase immunoreactivity. Nerves supplying the urethra outside the cavernous nerves may course posterior to the prostate. Along with afferent fibers, tyrosine hydroxylase immunoreactivity expressing neuron fibers, ie noradrenergic nerves, traveling in the cavernous nerves may increase urethral resistance or regulate the reflex mechanisms controlling continence.

    ABSTRACT: Over the past 15 years, significant advances have been made in the treatment of erectile dysfunction (ED). The most significant of these advances has been pharmacological treatment of ED with phosphodiesterase type 5 (PDE5) inhibitors. This therapy greatly increased the awareness of ED and has helped stimulate research into the underlying causes of ED. While treatment with PDE5 inhibitors continues to be the current therapy of choice, approximately 40% of men treated with PDE5 inhibitors fail to have significant improvement in erectile function and PDE5 inhibitors do not reverse the vasculopathic processes associated with ED. With this in mind, new therapies must be developed. The treatment with angiogenic growth factors such as vascular endothelial cell growth factor (VEGF) may be one such therapy. This review will focus on defining key terms in the angiogenic process, angiogenic growth factors, and different delivery methods, and summarize results from angiogenic therapies for the treatment of ED. A review of the literature was performed on all angiogenic therapies for the treatment of ED. A brief review on the angiogenic factors was also performed. Angiogenic therapies for the treatment of ED are possible and promising; however, further investigation is needed to advance clinically. Although numerous studies have now employed angiogenic factors for the possible treatment of ED in several animal models, we are still not at the point to begin human investigations. Future studies need to examine proper dosage of the angiogenic agent, route of delivery, time course for delivery, and combination therapies.
