The impact of male infertility faculty on urology residency training.

The objective of this study was to determine the impact of having male infertility on urology residents' infertility training experience, surgical confidence, and In-Service-Exam Infertility/Sexual Medicine subscores. We electronically surveyed urology residents throughout the United States querying exposure to infertility faculty and fertility knowledge. Univariable and multivariable analysis was performed to determine predictors of higher In-Service Exam Infertility/Sexual Medicine sub-scores and self-rated infertility competency. Fifty-four of 72 respondents (75%) reported that male infertility comprises ≤10% of their training. Of the 63 residents who have a reproductive urologist on faculty, 66.7%, 47.6%, and 49.2% have scrubbed/observed a microsurgical varicocelectomy, vasectomy reversal and testicular sperm extraction, respectively. Residents exposed to infertility faculty are more likely to self-rate their infertility understanding as "excellent" or "good" (p = 0.04 and p = 0.02, respectively), and 14.4× more likely to feel confident performing infertility procedures, versus residents lacking faculty (p < 0.001). Residents having formal microsurgical training have better self-rated infertility understanding (p < 0.001), non-obstructive azoospermia management (p = 0.01), and competency performing infertility procedures (p < 0.001). Residents exposed to fertility faculty are more likely to feel confident performing fertility procedures after residency (p = 0.001). In conclusion, infertility comprises a minority of residency training. Most residents anticipate performing infertility procedures in practice, despite two-thirds lacking confidence performing these. Having an infertility faculty and formal microsurgical training improves residents' surgical confidence, non-obstructive azoospermia management, and global male infertility understanding. A structured educational curriculum may improve resident infertility training.

Sperm granulomas: Predictive factors and impacts on patency post vasectomy reversal.

The objective of this study was to identify factors that predict for sperm granuloma formation and the impact of sperm granuloma presence and quantity on vasectomy reversal (VR) outcomes. A cross sectional retrospective review of prospectively collected data, on the impact of granuloma on VR outcomes from a single academic center was performed. The impact of age, obstructive interval, intraoperative vasal fluid findings, anastomosis type, body mass index, tobacco use and total motile count (TMC) was determined. A total of 1550 men underwent VR between January 2000 and August 2019. Granulomas were present unilaterally in 23.3% (n = 361) and bilaterally in 14.2% (n = 220). On univariate analysis, increasing patient age negatively correlated with a larger number of granulomas (p = .011). Granuloma presence was associated with finding intact and motile sperm from the vasal stump intraoperatively (p = .001), and vasoepididymostomy anastomosis (p < .001). However, granuloma presence (and quantity) did not correlate with obstructive interval or maximum TMC. Tobacco use and body mass index (BMI) were not associated with granuloma presence. On multivariate analysis, granuloma quantity was not associated with TMC. Obstructive interval and vasovasostomy anastomosis were associated with higher TMC, while BMI was negatively associated with TMC. In conclusion, increasing age was negatively correlated with granuloma formation. Granuloma presence was associated with more favourable intraoperative fluid findings and anastomosis type, but not post-VR TMC, suggesting men with and without granulomas undergoing skilled microsurgery will have similar patency rates. Heavier men should be encouraged for weight loss prior to vasectomy reversal as increasing BMI was associated with lower TMC.

National opioid prescription patterns and patient usage after routine vasectomy.

Routine prescription of opioids after outpatient surgery is common. The main objective of this study was to determine urologist opioid prescribing patterns and patients' pain control medication regimens (opioid and anti-inflammatory) after vasectomy. We designed an anonymous seven-question electronic survey of urologists to assess vasectomy practice and post-vasectomy opioid prescriptions using the American Medical Association Physician Masterfile database. We then performed a retrospective internal telephone survey of men who had undergone vasectomy by a single surgeon (MKS). This telephone survey queried men about opioid prescription filling, opioid use and ibuprofen use. We received 136 (4.5%) electronic survey responses. 51.5% of urologists routinely prescribed opioids for post-vasectomy analgesia, despite 50.4% having 'no idea' how many patients actually used these. On internal telephone survey, 52.6% of patients who used opioids reported using ibuprofen as their primary pain medication, versus 92.6% of patients who did not use opioids (p = .004). Ibuprofen use was associated with using fewer opioid tablets (p = .003). Using ≥1 opioid tab was associated with increased odds of not using ibuprofen as the primary pain medication (OR 11.2, 95% CI 2.39-83.0, p = .005). In conclusion, integration of practice guidelines may help standardise and minimise potentially unnecessary post-vasectomy opioid prescriptions.

What is the ideal antibiotic prophylaxis for intravesically administered Botox injection? A comparison of two different regimens.

INTRODUCTION: Onabotulinum toxin A (Botox®) administered intravescially is an effective treatment for idiopathic detrusor overactivity, of which urinary tract infections (UTIs) are a common complication. The purpose of this study was to compare two prophylactic antibiotic regimens with the goal of decreasing UTI rates following intravesically administered Botox® injection. MATERIALS AND METHODS: A retrospective review of two groups of patients undergoing intravesically administered Botox® injections was performed-one with idiopathic and one with neurogenic detrusor overactivity. One group received a dose of ceftriaxone intramuscularly (IM) at the time of Botox® injection, and a second group received a 3-day course of a fluoroquinolone orally starting the day before the procedure. The rate of postprocedure UTI was examined using a χ2 test. A secondary analysis was performed using logistic regression modeling to test the association between clinical characteristics and antibiotic regimen and risk of postprocedure UTIs. RESULTS: Botox® injections were performed on 284 patients: 236 received a single dose of ceftriaxone IM and 48 received 3 days of a fluoroquinolone orally. The UTI rate was significantly lower in the fluoroquinolone group (20.8%) vs. the cephalosporin group (36%), p = 0.04. Predictors of postprocedure UTIs included single dose of antibiotics IM [odds ratio (OR 2.80, p = 0.02] and a positive preprocedure urine culture (OR 1.31, p = 0.03). CONCLUSIONS: We found a significantly lower rate of UTIs when patients received a 3-day course of a fluoroquinolone orally as opposed to a single dose of a third-generation cephalosporin IM. Patients with a positive preprocedure culture might benefit from an even longer duration of antibiotics at the time of Botox® injection.

bHLH proneural genes as cell fate determinants of entero-endocrine cells, an evolutionarily conserved lineage sharing a common root with sensory neurons.

Entero-endocrine cells involved in the regulation of digestive function form a large and diverse cell population within the intestinal epithelium of all animals. Together with absorptive enterocytes and secretory gland cells, entero-endocrine cells are generated by the embryonic endoderm and, in the mature animal, from a pool of endoderm derived, self-renewing stem cells. Entero-endocrine cells share many structural/functional and developmental properties with sensory neurons, which hints at the possibility of an ancient evolutionary relationship between these two cell types. We will survey in this article recent findings that emphasize the similarities between entero-endocrine cells and sensory neurons in vertebrates and insects, for which a substantial volume of data pertaining to the entero-endocrine system has been compiled. We will then report new findings that shed light on the specification and morphogenesis of entero-endocrine cells in Drosophila. In this system, presumptive intestinal stem cells (pISCs), generated during early metamorphosis, undergo several rounds of mitosis that produce the endocrine cells and stem cells (ISCs) with which the fly is born. Clonal analysis demonstrated that individual pISCs can give rise to endocrine cells expressing different types of peptides. Immature endocrine cells start out as unpolarized cells located basally of the gut epithelium; they each extend an apical process into the epithelium which establishes a junctional complex and apical membrane specializations contacting the lumen of the gut. Finally, we show that the Drosophila homolog of ngn3, a bHLH gene that defines the entero-endocrine lineage in mammals, is expressed and required for the differentiation of this cell type in the fly gut.

Continuous saline bladder irrigation for two hours following transurethral resection of bladder tumors in patients with non-muscle invasive bladder cancer does not prevent recurrence or progression compared with intravesical Mitomycin-C.

BACKGROUND: Intravesical Mitomycin-C (MMC) following transurethral resection of bladder tumor (TURBT), while efficacious, is associated with side effects and poor utilization. Continuous saline bladder irrigation (CSBI) has been examined as an alternative. In this study we sought to compare the rates of recurrence and/or progression in patients with NMIBC who were treated with either MMC or CSBI after TURBT. METHODS: We retrospectively reviewed records of patients with NMIBC at our institution in 2012-2015. Perioperative use of MMC (40 mg in 20 mL), CSBI (two hours), or neither were recorded. Primary outcome was time to recurrence or progression. Descriptive statistics, chi-squared analysis, Kaplan-Meier survival analysis, and Cox multivariable regression analyses were performed. RESULTS: 205 patients met inclusion criteria. Forty-five (22.0%) patients received CSBI, 71 (34.6%) received MMC, and 89 (43.4%) received no perioperative therapy. On survival analysis, MMC was associated with improved DFS compared with CSBI (p = 0.001) and no treatment (p = 0.0009). On multivariable analysis, high risk disease was associated with increased risk of recurrence or progression (HR 2.77, 95% CI: 1.28-6.01), whereas adjuvant therapy (HR 0.35, 95% CI: 0.20-0.59) and MMC (HR 0.43, 95% CI: 0.25-0.75) were associated with decreased risk. CONCLUSIONS: Postoperative MMC was associated with improved DFS compared with CSBI and no treatment. The DFS benefit seen with CSBI in other studies may be limited to patients receiving prolonged irrigation. New intravesical agents being evaluated may consider saline as a control given our data demonstrating that short-term CSBI is not superior to TURBT alone.

Assessing quality of care through client satisfaction at an interprofessional student-run free clinic.

Student-run free clinics (SRFCs) have become important contributors not only to improve access to primary-care services for homeless and uninsured populations but also to enhance health sciences student education. In order for SRFCs to reliably provide high quality healthcare services and educationally benefit students, it is imperative to assess client perceptions of the quality of care provided. The objective of this study was to evaluate the delivery of healthcare services through a client satisfaction questionnaire at the University of California, Los Angeles Mobile Clinic Project (UCLA MCP). From 2012 to 2015, 194 questionnaires that addressed demographic information, satisfaction with services and client outcomes were analysed. Satisfaction scores were evaluated on a four-point scale and differences in the composite satisfaction scores were assessed using Mann-Whitney U-tests. Half (50%) of the client respondents report that UCLA MCP is their primary source of health care (MCP primary care clients), while 81.3% reported that the clinic improved access to other healthcare resources. Overall, clients are highly satisfied with their experiences (Range: 3.5-3.9) and 62% have recommended our services to others. While MCP primary-care clients report significantly higher satisfaction scores than non-primary-care clients on average (p < 0.01), the mean composite scores for all subgroups are consistently high. The UCLA MCP clients perceive the clinic to provide high-quality healthcare services. This article presents a framework that may help other SRFCs evaluate clients' perception of the quality of their care, an essential building block for effective physician-client relationships.

Association Between Hematologic and Inflammatory Markers and 31 Thrombotic and Hemorrhagic Events in Berlin Heart Excor Patients.

Bleeding and thrombotic events remain a significant cause of morbidity in pediatric patients supported with ventricular assist devices (VADs). The objective of this study is to identify the association between markers of anticoagulation and bleeding and thrombosis events during Berlin Heart ExCor support. A retrospective, single-center analysis of 9 patients supported with the Berlin Heart ExCor was performed. Inflammatory and anticoagulation parameters including C-reactive protein, fibrinogen, partial thromboplastin time (PTT), and platelet count were measured at 48 and 24 h before and after bleeding or thrombosis events. Patients served as their own controls, and the same parameters were measured during a control period where subjects did not experience either event. All patients received the anticoagulation regimen proposed by Berlin Heart. A total of 31 bleeding or thrombotic events were identified and matched to 18 control events. Patient with predominantly thrombotic events tended to weigh less than those with bleeding events (Δ7.7 kg, p < 0.001). PTT levels were higher before and after bleeding (Δ17.36, p = 0.002) and thrombosis (Δ8.75, p < 0.001) events relative to control. Heparin dose decreased after a thrombosis event (Δ-5.67, p = 0.097), and this decrease was significantly different from control (p = 0.032). Non-collinearity between heparin dose and PTT should prompt further inflammatory and hematological investigation. In addition, heavier patients were more prone to bleeding complications. The role of inflammation in the development of thrombus or hemorrhages in the pediatric VAD population needs to be studied further.

Untreated hypogonadism and testosterone replacement therapy in hypogonadal men are associated with a decreased risk of subsequent prostate cancer: a population-based study.

We sought to understand the relationship between hypogonadism and testosterone replacement therapy (TRT) in hypogonadal men on the risk of developing localized and metastatic prostate cancer. We used the Merative MarketScan database of commercial claims encounters to identify men diagnosed with hypogonadism. These men were matched to eugonadal men who served as controls. Multivariate negative binomial regression analysis of prostate cancer diagnoses, hypogonadism, and TRT in hypogonadal men adjusting for various known confounding factors was used to understand the impact of hypogonadism and TRT on prostate cancer risk. We identified 3,222,904 men who met inclusion criteria, of which 50% were diagnosed with hypogonadism (1,611,452) and each were matched to a control (1,611,452). The incidence of prostate cancer was 2.16%, 1.55%, and 1.99% in eugonadal controls, hypogonadal men on TRT, and hypogonadal men without TRT, respectively (p < 0.001). Untreated hypogonadism was independently associated with a decreased risk of localized prostate cancer (IRR 0.46, 95% CI 0.43-0.50, p < 0.001) compared to eugonadal controls. Hypogonadal men on TRT also had a significantly decreased risk of localized prostate cancer (IRR 0.49, 95% CI 0.45-0.53, p < 0.001). Furthermore, hypogonadal men on TRT (IRR 0.21, 95% CI 0.19-0.24, p < 0.001) or without TRT (IRR 0.20, 95% CI 0.18-0.22, p < 0.001) both had significantly decreased risk of metastatic prostate cancer, respectively. Our population-based analysis suggests that untreated hypogonadism in men is associated with a 50% decreased incidence of localized prostate cancer and an 80% decreased incidence of metastatic prostate cancer. TRT in hypogonadal men was also associated with a decreased risk of subsequent prostate cancer. Further research is needed to better understand the relationship between hypogonadism and TRT in hypogonadal men on the risk of subsequent prostate cancer.

Uncovering the Association Between Complete AZFc Microduplications and Spermatogenic Ability: The First Reported Series.

Purpose This article aims to report the first series of men with complete AZFc microduplications and their clinical and reproductive characteristics. Methods We sampled 3000 men who presented for reproductive urology evaluation from 2012-2020, of which 104 men underwent high-resolution Y-chromosome microarray testing, and five men were identified to have complete AZFc microduplications. Medical, surgical, and reproductive histories were obtained. Semen and hormonal parameters as well as response to fertility therapies were recorded. Results Five men were identified as having complete AZFc microduplications. The mean age was 33.75 years, representing 0.2% (5/3000) of men presenting for fertility investigation, 4.8% (5/104) of men undergoing microarray testing, and 21% (5/24) of men with AZFc abnormalities. Two of the men had prior undescended testicles and one had several autoimmune processes. The mean follicle-stimulating hormone (FSH) was 5.5 IU/L, luteinizing hormone (LH) 3.6 IU/L, and testosterone 14.56 nmol/L. One man was azoospermic, one man alternated between severe oligospermia and rare non-motile sperm, one had variable parameters, with one semen analysis demonstrating azoospermia and a second demonstrating a total motile sperm count (TMSC) of 4 ×106, one man was persistently oligospermic with TMSCs ranging 3.96-12.6 ×106, and one man initially had severe oligospermia, with a mean TMSC of 1.5 ×106, which increased to 21.7 ×106 after intervention (varicocele embolization, clomiphene citrate). This last man then fathered a spontaneous pregnancy. Conclusion AZFc complete microduplications are a rare cause of spermatogenic failure but not an uncommon form of AZFc abnormality. Clinically, they represent a heterogeneous group, having a variable reproductive potential. Cases should be managed on an individual basis.

Hyperandrogenism and Hyperestrogenism Secondary to Mixed Germ-Cell Testicular Tumor.

Testicular cancer with androgen and estrogen secretion is classically associated with Leydig cell tumors. Rare case reports have described this finding in germ-cell tumors along with signs of androgen and estrogen excess including gynecomastia and infertility. We report the case of a 19-year-old male with a non-seminomatous testicular germ-cell tumor found to have hyperandrogenism, hyperestrogenism, and suppression of central sex hormones. Similar findings may be underreported in the literature, and males with suspected testicular malignancy should be appropriately screened for signs of androgen and/or estrogen excess so they can be offered appropriate monitoring and counseling.

Complete testicular-epididymal dissociation presenting as adult chronic orchialgia.

Complete testicular epididymal dissociations are exceedingly rare conditions where the epididymis and the vas deferens are completely dissociated from the testicle. We present the case of a 46-year-old male with a history of chronic, intermittent and severe left testicular pain who was found to have a complete testicular epididymal dissociation at the time of surgical exploration and bilateral orchidopexy. Microsurgical approximation of the tail of the epididymis to the tunica albuginea of the testis with reapproximating the muscularis of the spermatic cord to the epididymal appendage was performed with subsequent relief of symptoms.

Global online interest in finasteride sexual side effects.

Prior literature has suggested that finasteride may negatively impact men's sexual health. In 2011, the Food and Drug Administration (FDA) provided a warning on finasteride drug labels to incorporate sexual side effects such as reduced libido and erectile dysfunction. We aimed to evaluate global online interest in finasteride sexual side effects, their penetrance and variation, and how they compared overtime. We also aimed to evaluate the influence of the FDA label warnings on web-based searches for finasteride side effects. We utilized Google search engine from January 2004 to December 2020 to include separate trends from web searches of "Propecia," "Propecia side effects," "finasteride", "finasteride side effects", and "post-finasteride syndrome" compared amongst the United States, United Kingdom, and Australia. We performed join-point regression analysis. We compared the annual relative search volume (ARSV) and annual percentage change (APC) to evaluate for loss or gain of interest in the respective key terms. We determined that the average ARSV for "finasteride" was 14.8% in 2004 and increased significantly to 57.3% in 2020 (APC: +9.25%, 95% CI 8 to 10.5, p < 0.001). Likewise, there was significant increased interest in "finasteride side effects" (APC: +20.7, p < 0.001) and "post-finasteride syndrome" (APC: +29.2; p < 0.001) in the United States overtime. Finally, when we compared trends before and after the FDA warnings, the average ASRV of "finasteride", "finasteride side effects", and "post-finasteride syndrome" all increased significantly (p = 0.001, p = 0.014, p < 0.001), respectively. Thus, it is evident that there is a global web-based interest in finasteride and its sexual health side effects, particularly after the FDA warning in 2011. There is boosted public awareness, and thus providers should have more detailed and careful conversations with patients prior to starting a 5α-reductase inhibitor such as finasteride.

Population-Based Assessment of Determining Predictors for Discharge Disposition in Patients with Bladder Cancer Undergoing Radical Cystectomy.

Objective: To assess predictors of discharge disposition­either home or to a CRF­after undergoing RC for bladder cancer in the United States. Methods: In this retrospective, cohort study, patients were divided into two cohorts: those discharged home and those discharged to CRF. We examined patient, surgical, and hospital characteristics. Multivariable logistic regression models were used to control for selected variables. All statistical tests were two-sided. Patients were derived from the Premier Healthcare Database. International classification of disease (ICD)-9 (<2014), ICD-10 (≥2015), and Current Procedural Terminology (CPT) codes were used to identify patient diagnoses and encounters. The population consisted of 138,151 patients who underwent RC for bladder cancer between 1 January 2000 and 31 December 2019. Results: Of 138,151 patients, 24,922 (18.0%) were admitted to CRFs. Multivariate analysis revealed that older age, single/widowed marital status, female gender, increased Charlson Comorbidity Index, Medicaid, and Medicare insurance are associated with CRF discharge. Rural hospital location, self-pay status, increased annual surgeon case, and robotic surgical approach are associated with home discharge. Conclusions: Several specific patient, surgical, and facility characteristics were identified that may significantly impact discharge disposition after RC for bladder cancer.

Mature Ovarian Cystic Teratoma Mimicking a Bladder Diverticulum in a 16-year-old Female.

A 16-year-old female was incidentally found to have an abnormal pelvic ultrasound while undergoing evaluation for mild scoliosis. A large, thick-walled, lobular, fluid-filled structure was found at midline in the pelvis that initially resembled bladder diverticula due to its anatomical position and sonographic appearance. Voiding cystourethrogram and computed tomography later revealed a large cystic mass originating from the right ovary. This report outlines a case of a mature cystic teratoma convincingly mimicking bladder anomaly on sonography.
