The association between elevated serum oestradiol levels and clinically significant erectile dysfunction in men presenting for andrological evaluation.

The goal of this study was to investigate the association between serum oestradiol levels and clinically significant erectile dysfunction in a cohort of men presenting for andrological evaluation. Retrospective review was conducted of patients that presented to a urologist with practice in andrology over an 18-month period. Patients completed the Male Sexual Health Questionnaire and had serum total testosterone and oestradiol measurements prior to 10:30 a.m. via immunoassay. t Tests, chi-square tests and multivariate logistic regression were used to compare clinical characteristics between those with adequate erectile function (erection scale score > 2) vs. clinically significant erectile dysfunction (erection scale score ≤ 2). Among 256 patients, average age was 49 years (SD 15), average serum oestradiol was 22.3 pg/ml (SD 10.6), and average serum total testosterone was 465.9 pg/ml (SD 206.3). On multivariate logistic regression, serum oestradiol was associated with clinically significant erectile dysfunction (OR 1.52 per SD increase, 95% CI 1.11-2.09, p = 0.009) when controlling for serum total testosterone, age, body mass index and smoking status. These results warrant future studies on the utility of measuring serum oestradiol in patients with erectile dysfunction and the use of aromatase inhibitors in patients with erectile dysfunction and elevated serum oestradiol.

Discordance between Ureteroscopic Biopsy and Final Pathology for Upper Tract Urothelial Carcinoma.

PURPOSE: We evaluated the discordance between ureteroscopic biopsy and surgical pathology findings for grading and staging upper tract urothelial carcinoma. We also sought to establish preoperative predictors of aggressive tumors. MATERIALS AND METHODS: We retrospectively reviewed the records of 314 patients who underwent ureteroscopic biopsy followed by surgical management of upper tract urothelial carcinoma from 2000 to 2016 at a total of 3 institutions. Our primary outcomes were muscle invasive (pT2 or greater) disease at surgical pathology and upgrading of clinical low grade tumors to pathological high grade. RESULTS: At biopsy 61% of the patients had clinical high grade tumors and 21% had subepithelial connective tissue invasion (cT1+). On final pathology 79% of the patients had pathological high grade tumors and 45% had stage pT2 or greater. On multivariate analysis advanced patient age, clinical high grade and cT1+ were independently associated with pT2 or greater. The combined presence of clinical high grade and cT1+ had 86% positive predictive value for muscle invasion while the combined absence of clinical high grade and cT1+ had 80% negative predictive value. The likelihood of missing invasion on biopsy in patients with muscle invasive disease was increased when biopsy fragments were limited to 1 mm or less. Of clinical low grade cases on biopsy 51% were upgraded at surgery. The presence of positive urine cytology was associated with an increased risk of upgrading but this was not statistically significant. CONCLUSIONS: Clinical high grade, cT1+ on biopsy and advanced patient age are independent risk factors for muscle invasive upper tract urothelial carcinoma. There is a significant risk of upgrading in patients with clinical low grade tumors on biopsy, especially when urine cytology is positive. The predictive value of biopsy can likely be improved by more extensive ureteroscopic sampling.

Three-Dimensional Photography for Quantitative Assessment of Penile Volume-Loss Deformities in Peyronie's Disease.

BACKGROUND: Non-curvature penile deformities are prevalent and bothersome manifestations of Peyronie's disease (PD), but the quantitative metrics that are currently used to describe these deformities are inadequate and non-standardized, presenting a barrier to clinical research and patient care. AIM: To introduce erect penile volume (EPV) and percentage of erect penile volume loss (percent EPVL) as novel metrics that provide detailed quantitative information about non-curvature penile deformities and to study the feasibility and reliability of three-dimensional (3D) photography for measurement of quantitative penile parameters. METHODS: We constructed seven penis models simulating deformities found in PD. The 3D photographs of each model were captured in triplicate by four observers using a 3D camera. Computer software was used to generate automated measurements of EPV, percent EPVL, penile length, minimum circumference, maximum circumference, and angle of curvature. The automated measurements were statistically compared with measurements obtained using water-displacement experiments, a tape measure, and a goniometer. OUTCOMES: Accuracy of 3D photography for average measurements of all parameters compared with manual measurements; inter-test, intra-observer, and inter-observer reliabilities of EPV and percent EPVL measurements as assessed by the intraclass correlation coefficient. RESULTS: The 3D images were captured in a median of 52 seconds (interquartile range = 45-61). On average, 3D photography was accurate to within 0.3% for measurement of penile length. It overestimated maximum and minimum circumferences by averages of 4.2% and 1.6%, respectively; overestimated EPV by an average of 7.1%; and underestimated percent EPVL by an average of 1.9%. All inter-test, inter-observer, and intra-observer intraclass correlation coefficients for EPV and percent EPVL measurements were greater than 0.75, reflective of excellent methodologic reliability. CLINICAL TRANSLATION: By providing highly descriptive and reliable measurements of penile parameters, 3D photography can empower researchers to better study volume-loss deformities in PD and enable clinicians to offer improved clinical assessment, communication, and documentation. STRENGTHS AND LIMITATIONS: This is the first study to apply 3D photography to the assessment of PD and to accurately measure the novel parameters of EPV and percent EPVL. This proof-of-concept study is limited by the lack of data in human subjects, which could present additional challenges in obtaining reliable measurements. CONCLUSION: EPV and percent EPVL are novel metrics that can be quickly, accurately, and reliably measured using computational analysis of 3D photographs and can be useful in describing non-curvature volume-loss deformities resulting from PD.

Trends in Opioid and Nonsteroidal Anti-Inflammatory Drug Use for Patients with Kidney Stones in United States Emergency Departments from 2015 to 2021.

Introduction: Renal colic is frequently treated with opioids; however, narcotic analgesic use can lead to dependence and abuse. We evaluated use trends of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) for pain management of kidney stones in United States emergency departments (EDs) from 2015 to 2021. Methods: Kidney stone encounters were identified using National Hospital Ambulatory Medical Care Survey data. We applied a multistage survey weighting procedure to account for selection probability, nonresponse, and population weights. Medication use trends were estimated through logistic regressions on the timing of the encounter, adjusted for selected demographic and clinical characteristics. Results: Between 2015 and 2021, there were an estimated 9,433,291 kidney stone encounters in United States EDs. Opioid use decreased significantly (annual odds ratio [OR]: 0.87, p = 0.003), and there was no significant trend in NSAID use. At discharge, male patients were more likely than females (OR: 1.93, p = 0.001) to receive opioids, and Black patients were less likely than White patients (OR: 0.34, p = 0.010) to receive opioids. Regional variation was also observed, with higher odds of discharge prescriptions in the West (OR: 3.15, p = 0.003) and Midwest (OR: 2.49, p = 0.010), compared with the Northeast. Thirty-five percent of patients received opioids that were stronger than morphine. Conclusion: These results suggest improved opioid stewardship from ED physicians in response to the national opioid epidemic. However, regional variation as well as disparities in discharge prescriptions for Black and female patients underscore opportunities for continued efforts.

The Impact of Single-Use Cystoscopes on Clinical Time Workflow in an Outpatient Setting.

OBJECTIVE: To evaluate the change in overall clinical encounter time and clinical capacity after transitioning to single-use cystoscopes (Ambu A/S, Ballerup, Denmark) in an outpatient urology setting. METHODS: A single-institution prospective study in an outpatient urology procedure clinic was performed. Discrete categories for each portion of nursing care responsibilities were defined, and time spent during each category was recorded. Two separate clinic days were observed and analyzed: one where the clinic exclusively used reusable cystoscopes and the other after the transition to single-use cystoscopes occurred. Additionally, clinic schedules were reviewed from all procedure clinics in the 3-month periods before and after the transition to single-use cystoscopes. Outcomes included overall clinical encounter time and the number of procedures per clinic day. RESULTS: There were 12 flexible cystoscopies performed during each of the observed clinic days. Preliminary cystoscope cleaning and transportation tasks by nursing staff were eliminated when utilizing single-use cystoscopes. Average total encounter time decreased from 66 to 44 minutes, resulting in a 34% reduction in clinical encounter time. The median number of flexible cystoscopy procedures increased after the transition from 9 (IQR 7-12) to 16 (IQR 11-17), representing a 78% increase (P = .003). CONCLUSION: Transition to a completely single-use cystoscopy outpatient procedure clinic improved clinical efficiency and facilitated an increased number of procedures per clinic day.

Longitudinal Changes in the Operative Experience for Junior Urology Residents.

OBJECTIVE: To evaluate longitudinal trends in surgical case volume among junior urology residents. There is growing perception that urology residents are not prepared for independent practice, which may be linked to decreased exposure to major cases early in residency. METHODS: Retrospective review of deidentified case logs from urology residency graduates from 12 academic medical centers in the United States from 2010 to 2017. The primary outcome was the change in major case volume for first-year urology (URO1) residents (after surgery internship), measured using negative binomial regression. RESULTS: A total of 391,399 total cases were logged by 244 residency graduates. Residents performed a median of 509 major cases, 487 minor cases, and 503 endoscopic cases. From 2010 to 2017, the median number of major cases performed by URO1 residents decreased from 64 to 49 (annual incidence rate ratio 0.90, P < .001). This trend was limited to oncology cases, with no change in reconstructive or pediatric cases. The number of major cases decreased more for URO1 residents than for residents at other levels (P-values for interaction <.05). The median number of endoscopic cases performed by URO1 residents increased from 85 to 194 (annual incidence rate ratio 1.09, P < .001), which was also disproportionate to other levels of residency (P-values for interaction <.05). CONCLUSION: There has been a shift in case distribution among URO1 residents, with progressively less exposure to major cases and an increased focus on endoscopic surgery. Further investigation is needed to determine if this trend has implications on the surgical proficiency of residency graduates.

National Implementation and Evaluation of a Virtual Subinternship in Urology.

OBJECTIVE: To conduct a nationwide evaluation of student and program director (PD) perspectives of virtual subinternships that took place during the COVID-19 pandemic. MATERIALS AND METHODS: In December 2020, we distributed anonymous surveys to all 534 urology residency applicants and 161 urology PDs at academic medical centers across the United States to evaluate virtual subinternships. Surveys assessed curriculum composition, goals, satisfaction, barriers, and future reusability. The primary outcome was overall satisfaction with the subinternship, evaluated on a 5-point Likert scale. RESULTS: The survey was completed by 174 students (33%) and 82 PDs (51%), including 81 students (47%) and 32 PDs (41%) who participated in virtual subinternships at 29 institutions. Overall, 77% of students and 78% of PDs rated the electives "excellent" or "very good." On ordinal logistic regression, higher student ratings were associated with duration ≥3 weeks (odds ratio [OR] 4.64, P = .003) and class size ≤4 students (OR 3.33, P = .015). Higher PD ratings were associated with full-time electives (OR 11.18, P = .019), class size ≤4 students (OR 13.99, P = .042), and utilization of the standardized Guidebook from the Society of Academic Urologists (OR 11.89, P = .038). The most commonly reported challenge to the subinternship's efficacy was lack of hands-on learning (87% of students and 81% of PDs). Looking forward, 45% of students and 66% of PDs recommended incorporating virtual components into future electives. CONCLUSION: The virtual subinternship was a coordinated nationwide initiative to provide urologic education to medical students during a pandemic. The most successful courses were structured with longer duration, full-time commitment, and small class size.

Predicting Sepsis in Patients with Ureteral Stones in the Emergency Department.

Background: In the absence of overt infection signs, clinical criteria for early intervention in patients with ureteral stones are poorly defined. We aimed to develop a model that can identify patients who are at risk for developing sepsis if discharged home from the emergency department (ED). Materials and Methods: We retrospectively reviewed patients between January 2010 and December 2019 who were discharged from the ED after diagnosis of ureteral stones. The primary outcome was sepsis requiring urgent surgical decompression. We used multivariable logistic regression to identify predictors of sepsis. We refined the model using backward stepwise regression with a threshold p-value of 0.05. Results: We identified 1331 patients who were discharged from the ED with ureteral stones. Of these patients, 22 (2%) subsequently developed sepsis requiring urgent decompression. In the initial multivariable model, female gender (odds ratio [OR]: 2.82, p = 0.039) and urine white blood cells (WBCs) (OR: 1.02 per cell count, p < 0.001) were predictive of sepsis. After performing backward stepwise regression, female gender, urine WBCs, and leukocytosis (WBCs >15,000/mm3) met criteria for inclusion in the model. A logistic model including these variables predicted sepsis with an internally cross-validated area under the curve (AUC) of 0.79. Among patients with urine cultures completed in the ED, rates of sepsis were 9% in patients with positive cultures and 1% in patients with negative cultures (p < 0.001). Antibiotic usage was not protective against developing sepsis. Conclusions: Sepsis is a rare complication among patients with ureteral stones selected for conservative management. The presence of elevated urine WBCs and female gender can help identify patients who are at risk of developing sepsis. Patients with risk factors should be managed with an increased index of suspicion for infection and may benefit from early intervention to reduce the risk of sepsis. Sepsis is more common in patients with positive urine cultures.

Promoting Organizational Change: A Urology Department-wide Wellness Program to Reduce Burnout.

INTRODUCTION: We developed a comprehensive wellness initiative to address burnout with specific interventions targeted at faculty, residents, nurses, administrators, coordinators, and other departmental personnel. METHODS: A department-wide wellness initiative was implemented in October 2020. General interventions included monthly holiday-themed lunches, weekly pizza lunches, employee recognition events, and initiation of a virtual networking board. Urology residents received financial education workshops, weekly lunches, peer support sessions, and exercise equipment. Faculty were offered personal wellness days to use at their discretion at no penalty to their calculated productivity. Administrative and clinical staff were given weekly lunches and professional development sessions. Pre- and post-intervention surveys included a validated single-item burnout instrument and the Stanford Professional Fulfillment Index. Outcomes were compared using Wilcoxon rank-sum tests and multivariable ordinal logistic regression. RESULTS: Among 96 department members, 66 (70%) and 53 (55%) participants completed the pre- and post-intervention surveys, respectively. Burnout scores were significantly improved after the wellness initiative (mean 2.06 vs 2.42, mean difference -0.36, P = .012). An improvement was also observed in the sense of community (mean 4.04 vs 3.36, mean difference 0.68, P < .001). Adjusting for role group and gender, completion of the curriculum was associated with decreased burnout (OR 0.44, P = .025), increased professional fulfillment (OR 2.05, P = .038), and increased sense of community (OR 3.97, P < .001). The highest-rated components were monthly gatherings (64%), sponsored lunches (58%), and employee of the month (53%). CONCLUSIONS: A department-wide wellness initiative with group-specific interventions can help reduce burnout and may improve professional fulfillment and workplace community.

Impact of an Acute Care Urology Service on Timelines and Quality of Care in the Management of Nephrolithiasis.

Background: The acute care surgery model has led to improved outcomes for emergent surgical conditions, but similar models of care have not been implemented in urology. Our department implemented an acute care urology (ACU) service in 2015, and the service evolved in 2018. We aimed to evaluate the impact of the ACU model on the management of nephrolithiasis. Materials and Methods: We conducted a retrospective review of all patients with urology consults in the emergency department for nephrolithiasis, who required surgical intervention from 2013 to 2019. Patients were divided into three cohorts based on date of consultation: Pre-ACU (2013-2014), Phase 1 (2015-2017), and Phase 2 (2018-2019). Results: We identified 733 patients with nephrolithiasis requiring intervention (162 pre-ACU, 334 Phase 1, and 237 Phase 2). Before ACU implementation, median time from consult to definitive intervention was 36 days. After ACU implementation, median time to intervention decreased to 22 days in Phase 1 (p < 0.001) and 15 days in Phase 2 (p < 0.001). On multivariable Cox regression, the hazard of definitive intervention improved in Phase 1 (hazard ratio [HR] 1.90, p < 0.001) and in Phase 2 (HR 1.80, p < 0.001). Rates of primary definitive intervention without initial decompression and loss to follow-up were also significantly improved, compared to the pre-ACU cohort. Conclusions: Implementation of a structured ACU service was associated with improved time to treatment for patients with acute nephrolithiasis, as well as increased primary definitive intervention and improved follow-up care. This model of care has potential to improve patient outcomes for nephrolithiasis and other acute urological conditions.

Reimagining the Away Rotation: A 4-Week Virtual Subinternship in Urology.

OBJECTIVE: To develop and evaluate the first 4-week virtual subinternship in urology. DESIGN: Following a needs assessment, we established four course objectives: to teach foundational knowledge, assess students' abilities, highlight our program culture, and evaluate students' compatibility with our program. To meet these objectives, we developed a virtual curriculum that consisted of department conferences, small group didactic sessions, clinical/surgical encounters, interactive online modules, and informal sessions. At the conclusion of the subinternship, we sent anonymous surveys to students and physicians to measure success in meeting the course objectives. Student learning was measured using the framework of the Accreditation Council for Graduate Medical Education (ACGME) core competencies. SETTING: The study was conducted at Columbia University Irving Medical Center, a tertiary care academic institution. PARTICIPANTS: Over a 2-month span, the virtual subinternship enrolled a total of 8 fourth-year medical students from 7 different medical schools in 5 different states. All residents and attending urologists in the Columbia University Department of Urology were involved in teaching. RESULTS: Overall, 100% of students and 63% of physicians rated the elective as "very good" or "excellent." The highest-rated components of the elective were the didactic curriculum and online modules. All course objectives were met, especially teaching foundational knowledge and highlighting program culture. Students reported high learning scores in all ACGME core competencies and urologic subspecialties, as well as increased confidence in managing a range of urologic conditions. The majority of students and physicians recommended incorporating virtual educational tools into future urology electives, particularly didactic sessions, online modules, and conferences/Grand Rounds presentations. CONCLUSIONS: A virtual subinternship in urology is a novel and successful model to enable student education, assessment, demonstration of program culture, and evaluation of student-program fit. This curriculum can serve as a template and springboard for the effective integration of virtual learning into surgical education.

Efficacy of an Online Blended Learning Curriculum to Improve Medical Student Urologic Education.

OBJECTIVE: During the COVID-19 pandemic, limitations on in-person medical school clerkships created a deficit in urologic learning opportunities. We sought to develop and evaluate a blended curriculum of interactive online modules with small-group discussion to enhance the educational experience for medical students in urology. MATERIALS AND METHODS: We created a curriculum of four online case-based urology modules. Between July and October 2020, 14 fourth-year medical students completed the modules. Students answered questions on a discussion board and engaged in asynchronous dialogue with 16 physicians, in addition to a weekly live review session. Students and physicians completed anonymous surveys to assess satisfaction and perceived learning outcomes, with questions scored on a 5-point Likert scale. RESULTS: Thirteen students (93% response rate) and 12 physicians (75% response rate) completed the survey. Overall, 12/13 students and 11/12 physicians "strongly agree" or "somewhat agree" that the modules improved the rotation. Students and physicians perceived that the modules were effective for learning/teaching foundational knowledge (average ratings 4.8 and 4.5, respectively) and facilitating performance assessment (4.4 and 4.0). Students reported high learning scores across multiple Accreditation Council for Graduate Medical Education core competencies, and 12/13 students found the modules fun/engaging. The majority of students (12/13) and physicians (10/12) felt that the online modules should be incorporated into future urology electives. CONCLUSIONS: A blended learning curriculum utilizing online modules is an effective tool for enhancing urologic education, improving perceived learning outcomes and facilitating performance assessment. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s40670-021-01427-3.

Changing the Status Quo: Developing a Virtual Sub-Internship in the Era of COVID-19.

PROBLEM: Subinternships are integral to medical education as tools for teaching and assessing fourth-year medical students. Social distancing due to COVID-19 has precluded the ability to offer in-person subinternships - negatively impacting medical education and creating uncertainty surrounding the residency match. With no precedent for the development and implementation of virtual subinternships, the Society of Academic Urologists (SAU) developed an innovative and standardized curriculum for the Virtual Subinternship in Urology (vSIU). METHODS: The vSIU committee's mandate was to create a standardized curriculum for teaching foundational urology and assessing student performance. Thirty-three members from 23 institutions were divided into working groups and given 3 weeks to develop 10 modules based on urologic subspecialties, Accreditation Council for Graduate Medical Education core competencies, technical skills training and student assessment. Working groups were encouraged to develop innovative learning approaches. The final curriculum was assembled into the "vSIU Guidebook." RESULTS: The vSIU Guidebook contains 212 pages - 64 pages core content and 2 appendices (patient cases and evaluations). It outlines a detailed 4-week curriculum with a sufficient volume of resources to offer a completely adaptable virtual course with the same rigor as a traditional subinternship. Modules contain curated teaching resources including journal articles, lectures, surgical videos and simulated clinical scenarios. Innovative learning tools include reflective writing, mentorship guidelines, videoconference-based didactics, surgical simulcasting and virtual technical skills training. The guidebook was disseminated to program directors nationally. NEXT STEPS: The vSIU is the first virtual subinternship in any specialty to be standardized and offered nationally, and it was implemented by at least 19 urology programs. This curriculum serves as a template for other specialties looking to develop virtual programs and feedback from educators and students will allow the curriculum to evolve. As the pandemic continues to challenge our paradigm, this rapid and innovative response exemplifies that the medical community will continue to meet the needs of an ever-changing educational landscape.

Guideline-Discordant Preoperative Gentamicin Dosing and the Risk of Gentamicin Associated Nephrotoxicity in Urologic Surgery.

OBJECTIVE: To determine the rate of and predictors for guideline-discordant preoperative gentamicin dosing in urologic surgery and to assess the risk of nephrotoxicity in patients who receive the recommended high-dose prophylaxis. MATERIALS AND METHODS: We retrospectively reviewed all adult patients who received preoperative gentamicin for urologic surgery from January 1, 2017 - October 3, 2019. Doses were categorized as guideline-concordant or -discordant using a cutoff of 4.5 mg/kg dosing weight. We used multivariable logistic regression to identify predictors for guideline-discordant dosing. Postoperative kidney injury was assessed using RIFLE criteria. RESULTS: Among 2134 patients, 89% received a preoperative dose ≤ 4.5 mg/kg. Older age (70+ years) and endoscopic surgery were significant risk factors for guideline-discordant dosing (OR 2.54, P< 0.001; OR 6.21, P<0.001). Among 735 patients with complete data, there was no significant difference in the risk of kidney injury between those who received a dose less than 4.5 mg/kg and those who received a higher dose (OR 0.89, 95% CI: 0.26 - 2.99, P = 0.75). CONCLUSION: Preoperative gentamicin is commonly administered at lower than recommended doses for urologic surgery. Older age and endoscopic surgery are significant predictors of guideline-discordant dosing. The risk of kidney injury following high-dose preoperative gentamicin for urologic procedures is likely comparable to the risk at lower doses.

Telemedicine in management of genitourinary malignancies: Patient and physician perspectives.

PURPOSE: The rapid expansion of telemedicine has presented a challenge for the care of patients with genitourinary malignancies. We sought to assess patient and physician perspectives on the use of telemedicine for genitourinary cancer care. METHODS: We conducted a prospective cross-sectional study of patients who had telemedicine visits with urology, medical oncology, or radiation oncology for management of genitourinary malignancies from July-August 2020. Patients and physicians each received a questionnaire regarding the telemedicine experience. Responses were scored on a 5-point Likert scale. The primary outcomes of the study were patient and physician satisfaction. RESULTS: Of the 115 patients who enrolled, we received 96 patient responses and 46 physician responses. Overall, 77% of patients and 70% of physicians reported being "extremely satisfied" with the telemedicine encounter. Satisfaction was high among all components of the encounter including patient-physician communication, counseling, shared decision making, time spent, timeliness and efficiency, and convenience. Additionally, 78% of patients and 85% of physicians "strongly agreed" that they were able to discuss sensitive topics about cancer care as well as they could at an in-person visit. Nine telemedicine visits (9%) encountered technological barriers. Technological barriers were associated with lower overall satisfaction scores among both patients and physicians (p ≤ 0.01). CONCLUSION: We observed high levels of patient and physician satisfaction for telemedicine visits for management of genitourinary malignancies. Technological barriers were encountered by 9% of patients and were associated with decreased satisfaction.

High Response Rates to Neoadjuvant Chemotherapy in High-Grade Upper Tract Urothelial Carcinoma.

OBJECTIVE: To evaluate the impact of cisplatin-based neoadjuvant chemotherapy (NAC) in patients who underwent nephroureterectomy for high-grade (HG) upper tract urothelial carcinoma (UTUC). METHODS: Retrospective review was conducted of patients with HG UTUC from 2011 to 2017 who underwent nephroureterectomy at 2 institutions. Patients with eGFR >50 mL/min/1.73 m2 were considered eligible for NAC and were referred for evaluation of NAC prior to nephroureterectomy. Patient demographics, kidney function, clinical and pathologic response rates, and outcomes were analyzed. RESULTS: Of 95 patients with HG UTUC meeting inclusion criteria (mean age 72.3 years, mean preop eGFR 57.0 mL/min/1.73 m2), 61 patients were considered eligible for NAC with eGFR >50 mL/min/1.73 m2, of which 25 (41%) received NAC. Of the patients who received NAC, 80% (20/25) of the patients had clinical response on imaging and 80% (20/25) had pathologic response (

Beyond Curvature: Prevalence and Characteristics of Penile Volume-Loss Deformities in Men With Peyronie's Disease.

INTRODUCTION: Non-curvature penile deformities associated with loss of erect penile volume are often overlooked and have not been thoroughly investigated. AIM: To describe the prevalence and functional impact of penile volume-loss deformities in our cohort of men with Peyronie's disease (PD). METHODS: We retrospectively examined medical records of patients with PD consecutively evaluated by a specialized urologist from December 2012 to June 2016. We excluded patients with prior surgical correction of PD, prior penile prosthesis, and inadequate erection during office examination. All patients underwent deformity assessment of the erect penis after intracavernosal injection. The assessment included measurement of penile curvature; evaluation for hourglass deformities, indentations, and distal tapering; and application of axial force to assess for penile buckling. Prior to the deformity assessment, each patient completed the Male Sexual Health Questionnaire and was asked if he experienced psychological distress and functional impairment related to his penile deformity. MAIN OUTCOME MEASURE: The primary clinical parameters that we evaluated were presence or absence of axial instability, functional impairment, psychological distress, penile pain, erectile dysfunction, ejaculatory dysfunction, sexual dissatisfaction, decreased sexual activity, and decreased sexual desire. RESULTS: 128 patients met criteria for inclusion. 83 patients (65%) had volume-loss deformities. Unilateral indentations, hourglass deformities, and distal tapering were present in 50 (39%), 30 (23%), and 16 (13%) patients, respectively. Penile curvature <10° degrees was present in 115 patients (90%). After controlling for angle of curvature, patients with volume-loss deformities had significantly higher rates of axial instability (odds ratio [OR] = 3.5, P = .01) and psychological distress (OR = 2.6, P = .03), as well as decreased sexual activity (OR = 2.7, P = .02), than patients with non-volume-loss deformities. CONCLUSION: Volume-loss penile deformities are highly prevalent in men with PD. These deformities are associated with penile axial instability and psychological distress, which may contribute to decreased frequency of sexual activity. Margolin EJ, Pagano MJ, Aisen CM, et al.
