Critically Evaluating the Role for Postoperative Antibiotics in Patients Undergoing Urethroplasty With Buccal Mucosa Graft: A Claims Database Analysis

OBJECTIVE

To compare outcomes among patients undergoing first-time urethroplasty with buccal mucosa graft (BMG) who receive postoperative antibiotics vs those who do not.

METHODS

A retrospective cohort study was conducted using the TriNetX claims database between 2008-2022. Using CPT, ICD10, and LOINC codes, patients >18 years old undergoing primary urethroplasty with BMG who received an outpatient prescription for antibiotics between postoperative day 0-30 or did not were queried. Patients with positive preoperative urine culture or urinary tract infection (UTI) within 30days preoperatively were excluded. Surgical outcomes included 5-year revision rates and revision-free survival. Safety outcomes included new UTI within 30days, surgical site infection within 90days, or Clostridium difficile infection within 30days of urethroplasty.

RESULTS

We identified 884 patients (81% antibiotic cohort, 19% nonantibiotic cohort) that met inclusion criteria. Age at time of urethroplasty, suprapubic tube presence, and pre-existing medical comorbidities were comparable between cohorts (Table 1A). There was no difference in 5-year rates and revision-free survival for endoscopic revision (11.5% vs 9.5%, relative risk (RR) 1.2, 95% CI [0.7, 2.0], recurrence-free survival (RFS) log-rank P = .6), re-do urethroplasty (12.9% vs 13.7%, RR 0.9, 95% CI [0.6, 1.5], RFS log-rank P = .7), or all-cause revision (19.8% vs 17.7%, RR 1.1, 95% CI [0.8, 1.6], P = .5) between groups. Postoperative rates of UTI, surgical site infection, and C difficile infection were similar between groups.

CONCLUSION

In this large retrospective cohort study of patients undergoing urethroplasty with BMG, we observed no significant benefit from use of postoperative antibiotics on long-term revision rates or perioperative infectious complications.

A Phase II Trial of Intravesical Gemcitabine and Docetaxel in the Treatment of Bacillus Calmette-Guérin‒Naïve Nonmuscle-Invasive Urothelial Carcinoma of the Bladder

PURPOSE

Combination intravesical gemcitabine and docetaxel (GemDoce) has demonstrated efficacy as second-line therapy for patients with bacillus Calmette-Guérin (BCG)‒unresponsive nonmuscle-invasive urothelial carcinoma of the bladder (NMIBC). In the context of widespread BCG shortages, we performed a phase 2 prospective trial to assess GemDoce for BCG-naïve NMIBC.

MATERIALS AND METHODS

This study is a prospective, single-arm, open-label phase 2 trial for patients with BCG-naïve high-risk NMIBC. Intravesical GemDoce was given weekly for 6 weeks as induction followed by monthly maintenance therapy for 2 years among responders. The primary end point was 3-month complete response, and key secondary end points included adverse events (AEs) and 12-month recurrence-free survival.

RESULTS

Twenty-five patients were enrolled between August 2020 and August 2022 with median follow-up of 19.6 months. The pretrial pathologic stages were high-grade (HG) T1 with carcinoma in situ (CIS; n = 7), HGT1 without CIS (n = 6), HGTa (n = 9), and CIS alone (n = 3). The 3-month complete response rate was 100% and recurrence-free survival at 12 months was 92%. Two patients with pretrial HGT1 had HGT1 recurrences at 9 and 12 months. No patients progressed to T2 disease, underwent radical cystectomy, or had any radiographic evidence of progressive disease. Grade 1 AEs were common (23/25 patients) including hematuria, urinary frequency, urgency, and fatigue. Five patients (20%) experienced a grade 3 AE including hematuria and UTI.

CONCLUSIONS

In this single-arm phase 2 trial, GemDoce was well tolerated with promising efficacy for patients with BCG-naïve high-risk NMIBC.

The Impact of Hypogonadism on Surgical Outcomes Following Primary Urethroplasty: Analysis of a Large Multi-institutional Database

OBJECTIVE

To compare surgical outcomes among a cohort of eugonadal and hypogonadal patients undergoing primary urethroplasty (UP).

METHODS

A retrospective cohort study was conducted using TriNetX between 2008-2023. Patients who were eugonadal and hypogonadal (symptoms plus testosterone <300 ng/dL) prior to UP were compared. A subgroup analysis of hypogonadal patients was performed to compare those with testosterone replacement therapy (TRT) vs TRT-naïve prior to UP. Propensity-score matching was used to adjust for differences in comorbidities. Outcomes were 5-year revision rates and revision-free survival for endoscopic revision and redo UP following primary UP.

RESULTS

We identified 12,556 eugonadal and 488 hypogonadal patients (153 TRT+, 335 TRT-) undergoing UP. Median age at UP and follow-up was 55years and 5years, respectively. After propensity-score matching, we compared 477 eugonadal and 477 hypogonadal patients. Hypogonadal patients had a statistically significantly higher 5-year redo UP rate (11% vs 6%, relative risk [RR] 1.5 [95%CI, 1.2-2.2]; P = .01) when compared to eugonadal patients however there was no difference in 5-year rates of endoscopic revision (11% vs 11%, RR 1.0 [95%CI, 0.7-1.5]; P = 1.0). We observed no difference in 5-year revision-free survival time for endoscopic revision or redo UP between groups. Hypogonadal patients treated with TRT had a significantly higher 5-year redo UP rate (15% vs 7%, RR 1.8 [95%CI, 1.1-3.3]; P = .02) compared to hypogonadal patients that were TRT-naïve prior to UP. There was no difference in rates of endoscopic revision (14% vs 10%, RR 1.3 [95%CI, 0.7-2.4]; P = .2) between subgroups.

CONCLUSION

Pre-existing hypogonadism may modestly adversely affect surgical outcomes following primary UP based on data from a large, retrospective cohort study.

Medical School Rankings: Time to End or Time to Amend?

ABSTRACT

The recent decisions of several medical schools to no longer participate in the rankings published annually by U.S. News & World Report have added greater visibility to the issues surrounding medical school rankings than ever before. While these announcements garnered significant attention in academic medicine and from the lay public, the authors believe these events are unlikely to eliminate rankings in medical education. In this article, the authors outline the potential harms of rankings in higher education, provide a rationale for why they will likely endure despite recent scrutiny, and offer suggestions for prospective students and the academic medical community to engage with rankings in a more productive way. Criticisms of medical school rankings have been noted for decades, including their use of subjective information and data with questionable relevance to the quality of students' education or the outcomes of their educational experience, methodological concerns, and the potential harms of ranking systems (such as schools diverting their focus and resources away from initiatives that benefit students to improve their ranking). At the same time, rankings are ubiquitous in today's culture and are powerful in human decision-making, so there is reason to believe that medical school rankings may weather the current storm. Given these concerns, the authors suggest students continue to use a variety of resources to obtain information about medical schools and consider how each school fits with their own educational needs. The authors also encourage medical schools, medical education organizations, and governing medical bodies to suggest different metrics that reflect quality in medical education and that are of importance to applicants.

National Postoperative Opioid Prescribing Rates Following Pediatric Urology Procedures Before and After the 2018 American Academy of Pediatrics Challenge to Reduce Opioid Prescribing: A Claims Database Analysis

OBJECTIVE

To evaluate trends in opioid prescribing rates following pediatric urologic surgery.

METHODS

We queried the TriNetX Research database for patients under age 18 who underwent one of seven common pediatric urology procedures. We identified the proportion of patients that received an oral opioid prescription within 5days of surgery. The primary analysis evaluated the trend in postoperative opioid prescriptions using 3-month intervals from January 2010 to December 2022. We performed an interrupted time series analysis assessing trends in opioid prescribing patterns both before and after the American Academy of Pediatrics challenge.

RESULTS

Of the 81,644 pediatric urology procedures, 29,595 (36.2%) received a postoperative opioid prescription, including 29.8% of circumcisions, 25.8% of hydrocelectomies, 39.6% of hypospadias repairs, 42.7% of pyeloplasties, 42.8% of ureteral reimplants. For all procedures we observed rising rates of opioid prescribing, increasing by 0.9% per 3-month interval prior to the challenge statement release from 2010 to 2018. We observed an overall significant decrease in opioid prescribing by 2.2% per 3-month interval following the challenge statement release. Additionally, since 2018, there was a significant decrease in opioid prescribing in all of the race, ethnicity, and age cohorts.

CONCLUSION

Opioid prescribing following pediatric urology procedures has sharply decreased following the 2018 American Academy of Pediatrics challenge statement which underscores the value of cross-specialty quality improvement initiatives. Nonetheless, opioid prescribing remains high with potential racial or age disparities that warrant further investigation.

Long-Term Management of Problems in Cloacal Exstrophy: A Single-Institution Review

INTRODUCTION

Cloacal exstrophy (CE) is the most severe malformation of the exstrophy-epispadias complex. This study aims to discuss long-term sequela in a single major institution with a high volume of CE patients.

MATERIALS AND METHODS

A prospectively maintained database of 1490 patients on the exstrophy epispadias spectrum (145 cloacal exstrophy) from 1974 to 2023. The patient database was reviewed for CE patients >10 years of age for genitourinary, gastrointestinal, orthopedic, and psychosocial outcomes.

RESULTS

A total of 63 patients (43.4%) with ≥10 years of follow up were included for analysis. Thirty-nine (61.9%) patients were 18 years or older. Twenty-two (34.9%) patients were female and 39 (61.9%) male, 14 of whom were gender converted at birth. Two female patients conceived naturally and delivered via cesarean section. No male born CE patients had biological children. Catheterizable channels were common (45/63, 71.4%) and most (88.9%) were continent. Gastrointestinal diversion was managed mostly by colostomy (37/63, 58.7%). Three out of five (60.0%) patients who underwent PSARP were continent of stool. Twenty-two (34.9%) patients were wheelchair-bound. Psychosocial diagnoses included 52.4% (33/63) patients with anxiety/depression and 27.0% with chronic pain. Out of 56 patients evaluated by physical therapy, 75% were independent in ADL performance. Of patients older than 18, 79.5% (31/39) had attended college and 82.1% (32/39) were gainfully employed.

CONCLUSION

Advances in critical care, nutrition, gastrointestinal, orthopedic, and urologic management have resulted in survival rates approaching 100% among patients with CE. While these children face long-term sequela spanning various organ systems, many lead independent and fully-functional lives.

Effectiveness of Liposomal Bupivacaine With Bupivacaine Hydrochloride vs Bupivacaine Hydrochloride Alone as a Local Anesthetic for Children Undergoing Ambulatory Urologic Surgery: The Baby ORIOLES Randomized Clinical Trial

PURPOSE

We sought to determine if the addition of liposomal bupivacaine to bupivacaine hydrochloride improves opioid-free rate and postoperative pain scores among children undergoing ambulatory urologic surgery.

MATERIALS AND METHODS

A prospective, phase 3, single-blinded, single-center randomized trial with superiority design was conducted in children 6 to 18 years undergoing ambulatory urologic procedures between October 2021 and April 2023. Patients were randomized 1:1 to receive dorsal penile nerve block (penile procedures) or incisional infiltration with spermatic cord block (inguinal/scrotal procedures) with weight-based liposomal bupivacaine plus bupivacaine hydrochloride or bupivacaine hydrochloride alone. The primary outcome was opioid-free rate at 48 hours. Secondary outcomes included parents' postoperative pain measure scores, numerical pain scale scores, and weight-based opioid utilization at 48 hours and 10 to 14 days.

RESULTS

We randomized 104 participants, with > 98% (102/104) with complete follow-up data at 48 hours and 10 to 14 days. At interim analysis, there was no significant difference in opioid-free rate at 48 hours between arms (60% in the intervention vs 62% in the control group; estimated difference in proportion -1.9% [95% CI, -20%-16%]; P = .8). We observed no increased odds of patients being opioid-free at 48 hours with the intervention compared to the control group (OR 0.96 [95% CI 0.41-2.3]; P = .9). The trial met the predetermined futility threshold for early stopping. There was no difference in parents' postoperative pain measure scores, numerical pain scale scores, or opioid utilization at 48 hours or 10 to 14 days. No difference in adverse events was observed.

CONCLUSIONS

The addition of liposomal bupivacaine to bupivacaine hydrochloride did not significantly improve opioid-sparing effect or postoperative pain compared with bupivacaine hydrochloride alone among children ≥ 6 years undergoing ambulatory urologic surgery.

Assessment of musculoskeletal pain and surgical ergonomic parameters among members of the American Society of Pediatric Otolaryngology

OBJECTIVES

To assess rates of self-reported work-related pain and knowledge of ergonomic principles among fellowship trained pediatric otolaryngologists within the American Society of Pediatric Otolaryngology (ASPO). We hypothesized that pediatric otolaryngologists experience rates of musculoskeletal pain and injury similar to what has been reported among adult otolaryngologists and other surgical subspecialties.

METHODS

An IRB-approved survey was distributed to members of ASPO through email listserv. Collected variables included surgeon demographic information, practice settings, surgical volume, procedure types, work-related musculoskeletal pain-related metrics, modifying factors, and knowledge/attitudes on surgical ergonomics.

RESULTS

A total of 685 ASPO members were approached via email, of which 435 opened the survey email and 118 attending pediatric otolaryngologists completed the survey (response rate 27%). In all, 78% of respondents reported current or prior pain and/or injury attributed to performing surgery, 20% higher than that reported in the previous ergonomics survey of ASPO members in 2012. The most affected areas were neck/cervical spine (63%), shoulders/arms (44%), lower back/lumbar spine (36%), and hands/wrist (31%). Half of the respondents were diagnosed with musculoskeletal condition(s) attributed to performing surgery. Two-thirds required treatment (62% pharmacologic only, 9% pharmacologic and surgical intervention) for their work-related pain. Leveraging intermittent pauses during surgical procedures to adjust body position was the most reported method of addressing pain in the operating room. Only 21% report ever having received ergonomic training during their training or career.

CONCLUSION

Musculoskeletal pain associated with performing pediatric otolaryngology procedures is highly prevalent and has not attenuated despite increased awareness of surgical ergonomics. Results from this study underscore the need to develop standardized surgical ergonomics curricula for pediatric otolaryngologists and trainees.

Infantile versus childhood posterior urethral valve diagnosis: management patterns and clinical outcomes at opposite ends of the spectrum

BACKGROUND

Management patterns and outcomes are poorly defined in cases of late PUV diagnosis.

OBJECTIVE

To compare post-ablation management and clinical outcomes of patients with infantile (<1 year) versus childhood (>5 year) PUV diagnosis to gain insight into the pathologies at opposite ends of the PUV spectrum.

STUDY DESIGN

A multicenter retrospective cohort study was conducted using the TriNetX research network between 2006 and 2022. TriNetX synthesizes insurance claims and electronic medical record data for over 110 million patients from 92 healthcare organizations. We defined two cohorts: 1) The <1 year arm had an index diagnosis of PUV and cystoscopy with valve ablation within 1 year of life, 2) the >5 year arm had an index diagnosis of PUV and valve ablation after age 5. We report rates and time-to-first use of antispasmodics, alpha-blockers, CIC, bladder botox, enterocystoplasty or Mitrofanoff or secondary cutaneous vesicostomy, and CKD.

RESULTS

We identified 569 patients (323 <1 year; 246 >5 year). Median age at diagnosis was 1 month (median follow-up 8 years) and 9 years (median follow-up 10 years) for the <1 year and >5 year cohorts, respectively. Following ablation, both arms were primarily managed with antispasmodics, with no difference between groups. The >5 year arm was significantly more likely to receive alpha-blockers or bladder botox. The <1 year arm was significantly more likely to be started on CIC, undergo enterocystoplasty, Mitrofanoff or secondary cutaneous vesicostomy, or renal transplantation. The <1 year arm had significantly higher rates and shorter time-to-progression to all stages of CKD.

DISCUSSION

Despite higher utilization of conservative strategies among patients with a late PUV diagnosis, these patients had superior renal outcomes and low rates of progression to invasive treatments. Limitations include potential inaccuracies in medical coding as well as variations in thresholds to initiate CIC, perform surgical reconstruction, or proceed with renal transplantation at participating centers.

CONCLUSIONS

These findings provide evidence that a late PUV diagnosis reflects an overall milder disease process.

Does prophylactic antibiotics post pediatric pyeloplasty reduce the incidence of febrile UTIs?

PURPOSE

The use of postoperative prophylactic antibiotics in pediatric upper urinary tract reconstruction remains controversial. In this study, we examined whether low dose antibiotics administered following pediatric pyeloplasty reduce the incidence of febrile urinary tract infections at our institution. As a secondary outcome, in those patients with infection, additional analysis was performed to better quantify which patient population benefits the most from low dose prophylactic antibiotics.

METHODS

Institutional review board approval (IRB) was obtained. All methods were carried out in accordance with relevant guidelines and regulations. A retrospective study was performed in patients who underwent pyeloplasty (2011-2017) at our institution. Surgical approach (laparoscopic versus robotic assisted versus open, with or without internal JJ ureteral stent) were based on surgeon preference. Patients of 8 fellowship trained pediatric urologists were included in the study period. Patients with prior history of urologic interventions or other congenital genitourinary tract abnormalities were excluded. Demographics (age, gender, ethnicity, insurance status), prior history of culture proven urinary tract infection, surgical details (administration of perioperative antibiotics), and postoperative outcomes including; 1) re-admission 30 days post-surgery, 2) any urine cultures collected due to suspected urinary tract infection.

RESULTS

A total of 209 patients (149 boys, 60 girls) met our inclusion criteria with 55/209 (26%) receiving postoperative prophylactic antibiotics. The average age was 6 years (range: 2 months-18 years). Indwelling ureteral stent was used in 176 (84%) patients. Eleven patients (5%) had a culture-proven urinary tract infection within 30-days postoperatively. No significant differences were seen in postoperative complications or incidence of urinary tract infection when comparing surgical approaches, +/- ureteral stent, or the use of antibiotics. Secondary analysis noted statistically significant increase in post-operative urinary tract infection in younger children (2.8 v. 6.2 years, p = 0.02), those patients who had a positive preoperative urine culture (8/11, p = 0.01) and those with public health insurance (p = 0.038).

CONCLUSION

The incidence of postoperative urinary tract infection following pyeloplasty in our cohort was relatively low. There was a higher incidence of urinary tract infection in patients less than 3 years old. The use of antibiotics in patients post pyeloplasty did not appear to affect the incidence of post-operative urinary tract infection, however, they may have a role in children who have not yet potty trained and in patients with positive preoperative urine culture.

Do Articles Shared by Academic Medicine Social Media Influencers Drive Future Citation Rates?

OBJECTIVE

To assess the role of influential figures within social media (SoMe) in driving future citations.

METHODS

All original articles published in the Journal of Urology and European Urology in 2018 were identified. For each article, number of mentions on any SoMe platform, article's Twitter reach, and total citations were collected. Article characteristics such as type of study, article topic, and open access status were identified. Total academic research output was obtained for first and last authors of included articles. Influential SoMe figures were defined as users that tweeted about included articles and had over 2000 followers. For these accounts, we collected total followers, total tweets, engagement statistics, verification status, and academic characteristics such as total citations and total prior publications. The impact of SoMe, article, and academic characteristics on future citations was assessed using panel data regression analysis.

RESULTS

We identified 394 articles with 8895 total citations and 460 SoMe influencers. On panel data regression modeling, tweets about a specific article were associated with future citations (0.17 citations per tweet about an article, P < .001). SoMe influencer characteristics were not associated with increased citations (P > .05). The following non-SoMe-associated characteristics were predictive of future citations (P < .001): study type (prospective studies received 12.9 more citations than cross-sectional studies), open access status (4.3 citations more if open access, P < .001), and previously well-published first and last authors.

CONCLUSION

While SoMe posts are associated with increased visibility and higher future citation rates, SoMe influencers do not appear to drive these outcomes. Instead, high quality and accessibility were more predictive of future citability.

Safety and Efficacy of Long-Acting Liposomal Bupivacaine Plus Bupivacaine Hydrochloride for Dorsal Penile Block During Ambulatory Pediatric Urologic Surgery

This study evaluates the tolerability and efficacy of preoperative dorsal penile nerve block with Exparel plus bupivacaine hydrochloride in children>6 years old undergoing ambulatory urologic surgery. We demonstrate that the drug combination is well-tolerated, with appropriate analgesic efficacy in the recovery room as well as at 48-hour and 10-14 day follow-up periods. These preliminary data justify the need to perform a prospective, randomized trial comparing Exparel plus bupivacaine hydrochloride to other common local anesthetic regimens used in pediatric urologic surgery.

Abdominal Mass in a Phenotypic Female with 46,XY Differences in Sex Development

We present a case of a large intra-abdominal mass found to be localized pure seminoma within a retained gonad of a 53-year-old phenotypic female with 46,XY differences in sex development (DSD) and androgen insensitivity syndrome (AIS). Our management included extirpation of the mass with contralateral gonadectomy. Historically, patients with AIS would undergo gonadectomy to mitigate the lifetime risk of testicular germ cell tumor development; however, growing evidence suggests safety in retention and surveillance of these gonads into adulthood. This case highlights the importance of lifetime surveillance of patients with 46,XY DSD who elect to retain their gonads.

Perioperative opioid prescribing after male fertility procedures is associated with new persistent opioid use: retrospective analysis of a large claims database

OBJECTIVE

To assess the risk of new persistent opioid use in opioid-naïve men who underwent male fertility procedures.

DESIGN

Retrospective cohort study using a claims database.

SETTING

A database linking electronic medical record data and claims-assessing men who underwent fertility procedures between 2010 and 2021.

PATIENT(S)

Opioid-naïve men who underwent fertility procedures (open or laparoscopic varicocelectomy, spermatocele excision, and testicular excisional or incisional biopsy) without further surgical intervention requiring anesthesia in the 2 years after the index procedure. Those with and without perioperative opioid prescriptions were propensity score matched on age, race/ethnicity, smoking status, mental health diagnoses, and preoperative pain diagnoses.

INTERVENTION(S)

Perioperative opioid prescription.

MAIN OUTCOME MEASURE(S)

The primary outcome was the incidence of new persistent opioid use (opioid prescription 3-9 months after the index fertility procedure). The secondary outcome was prolonged opioid use (opioid prescription 9-24 months after the index fertility procedure).

RESULT(S)

A total of 387,565 men who underwent fertility procedures were identified, of whom 25.1% received an opioid prescription. After propensity score matching, 97,215 men were included; 4.7% of men who received a perioperative opioid prescription developed new persistent opioid use compared with 2.2% of those without a perioperative opioid prescription (risk ratio, 2.16; 95% confidence interval, 2.05-2.27; number needed to harm, 39). When assessing each unique fertility procedure independently, men who received perioperative opioids had statistically higher odds of developing new persistent opioid use for all procedure types. Men with new persistent opioid use were much more likely to go on and develop prolonged opioid use than men without new persistent opioid use.

CONCLUSION(S)

Opioid prescription after male fertility procedures is associated with a significant risk of new persistent opioid use, emphasizing the importance of judicious opioid prescribing for male fertility procedures.

Using Competing Risk of Mortality to Inform the Transition from Prostate Cancer Active Surveillance to Watchful Waiting

BACKGROUND

For men on active surveillance (AS) for prostate cancer (PCa), disease progression and age-related changes in health may influence decisions about pursuing curative treatment.

OBJECTIVE

To evaluate the predicted PCa and non-PCa mortality at the time of reclassification among men on AS, to identify clinical criteria for considering a transition from AS to watchful waiting (WW).

DESIGN, SETTING, AND PARTICIPANTS

Patients enrolled in a large AS program who experienced biopsy grade reclassification (Gleason grade increase) were retrospectively examined. All patients who had complete documentation of medical comorbidities at reclassification were included.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

A validated model was used to assess 10- and 15-yr untreated PCa and non-PCa mortalities based on patient comorbidities and PCa clinical characteristics. We compared the ratio of predicted PCa mortality with predicted non-PCa mortality ("predicted mortality ratio") and divided patients into four risk tiers based on this ratio: (1) tier 1 (ratio: >0.33), (2) tier 2 (ratio 0.33-0.20), (3) tier 3 (ratio 0.20-0.10), and (4) tier 4 (ratio <0.10).

RESULTS AND LIMITATIONS

Of the 344 men who were reclassified, 98 (28%) were in risk tier 1, 85 (25%) in tier 2, 93 (27%) in tier 3, and 68 (20%) in tier 4 for 10-yr mortality. Fifteen-year risk tiers were distributed similarly. The 23 (6.7%) men who met the "transition triad" (age >75 yr, Charlson Comorbidity Index >3, and grade group ≤2) had a 14-fold higher non-PCa mortality risk and a lower predicted mortality ratio than those who did not (0.07 vs 0.23, p < 0.001). The primary limitations of our study included its retrospective nature and the use of predicted mortalities.

CONCLUSIONS

At reclassification, nearly half of patients had a more than five-fold and one in five patients had a more than ten-fold higher risk of non-PCa death than patients having a risk of untreated PCa death. Despite a more significant cancer diagnosis, a transition to WW for older men with multiple comorbidities and grade group <3 PCa should be considered.

PATIENT SUMMARY

Men with favorable-risk prostate cancer and life expectancy of >10 yr are often enrolled in active surveillance, which entails delay of curative treatment until there is evidence of more aggressive disease. We examined a group of men on active surveillance who developed more aggressive disease, and found, nevertheless, that the majority of these men continued to have a dramatically higher risk of death from non-prostate cancer causes than from prostate cancer based on a risk prediction tool. For men older than 75 yr, who have multiple medical conditions and who do not have higher-grade cancer, it may be reasonable to reconsider the need for curative treatment given the low risk of death from prostate cancer compared with the risk of death from other causes.

Catheter-Associated Urinary Infections and Consequences of Using Coated versus Non-Coated Urethral Catheters-Outcomes of a Systematic Review and Meta-Analysis of Randomized Trials

Coated urethral catheters were introduced in clinical practice to reduce the risk of catheter-acquired urinary tract infection (CAUTI). We aimed to systematically review the incidence of CAUTI and adverse effects in randomized clinical trials of patients requiring indwelling bladder catheterization by comparing coated vs. non-coated catheters. This review was performed according to the 2020 PRISMA framework. The incidence of CAUTI and catheter-related adverse events was evaluated using the Cochran−Mantel−Haenszel method with a random-effects model and reported as the risk ratio (RR), 95% CI, and p-values. Significance was set at p < 0.05 and a 95% CI. Twelve studies including 36,783 patients were included for meta-analysis. There was no significant difference in the CAUTI rate between coated and non-coated catheters (RR 0.87 95% CI 0.75−1.00, p = 0.06). Subgroup analysis demonstrated that the risk of CAUTI was significantly lower in the coated group compared with the non-coated group among patients requiring long-term catheterization (>14 days) (RR 0.82 95% CI 0.68−0.99, p = 0.04). There was no difference between the two groups in the incidence of the need for catheter exchange or the incidence of lower urinary tract symptoms after catheter removal. The benefit of coated catheters in reducing CAUTI risk among patients requiring long-term catheterization should be balanced against the increased direct costs to health care systems when compared to non-coated catheters.

A Global Survey of Ergonomics Practice Patterns and Rates of Musculoskeletal Pain Among Urologists Performing Retrograde Intrarenal Surgery

PURPOSE

Retrograde intrarenal surgery (RIRS) requires awkward body posture for long durations. Few urologists receive ergonomics training despite the availability of ergonomics best practices utilized by other surgical specialties. We characterize ergonomics practice patterns and rates of musculoskeletal (MSK) pain among urologists performing RIRS.

METHODS

A web-based survey was distributed via the Endourological Society, the EAU, and social media. Surgeon anthropometrics and ergonomic factors were compared to ergonomics best practices. Pain was assessed with the Nordic Musculoskeletal Questionnaire (NMQ).

RESULTS

Overall, 519 of 526 participants completed the survey (99% completion rate). Ninety-three percent of urologists consider ergonomic factors when performing RIRS to reduce fatigue (68%), increase performance (64%), improve efficiency (59%), and reduce pain (49%). Only 16% received ergonomics training. Residents/fellows had significantly lower confidence in ergonomic technique compared to attending surgeons of any career length. Adherence to proper ergonomic positioning for modifiable factors were highly variable. On NMQ, 12-month rates of RIRS-associated pain in ≥1 body part, pain limiting activities of daily living, and pain requiring medical evaluation were 81%, 51%, and 29%, respectively. Annual case volume >150 cases (OR 0.55 [0.35-0.87]) and higher adherence to proper ergonomic techniques (OR 0.67 [0.46-0.97]) were independently associated with lower odds of pain. Limitations include a predominantly male cohort which hindered the ability to assess gender disparities in pain and ergonomic preferences.

CONCLUSION

Adherence to ergonomics best practices during RIRS is variable and may explain high rates of MSK pain among urologists. These results underscore the importance of utilizing proper ergonomic techniques and may serve as a framework for establishing ergonomics guidelines for RIRS.

Diagnostic and Management Strategies for Patients with Chronic Prostatitis and Chronic Pelvic Pain Syndrome

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common and often heterogenous condition that can have severe consequences on patient quality of life. In this review, we describe the pathophysiology, diagnostic work-up, and treatment of patients with CP/CPPS incorporating the most recent literature. Studies have demonstrated that CP/CPPS involves a complex pathophysiology, including infectious, immunologic, neurologic, endocrinologic, and psychologic etiologies, with frequent intersections between the different entities. Despite robust research assessing a variety of therapeutics targeting these etiologies, clinical trials have failed to identify an empiric treatment strategy applicable specifically to older adult male patients with CP/CPPS. As such, it can be challenging to manage older male patients with this condition. The advent of clinical phenotyping of patients with CP/CPPS has led to advances in tailored management strategies. Monomodal therapy has been largely unsuccessful because of the unclear and complex etiology of CPPS. As a result, CP/CPPS therapy has transitioned to a multimodal approach, including both pharmacologic and non-pharmacologic therapies. The best studied pharmacologic therapies include antibiotics, alpha-blockers, anti-inflammatory and immunomodulatory agents, phytotherapies, phosphodiesterase inhibitors, hormonal agents, neuromodulatory agents, and antidepressants. The best studied non-pharmacological therapies include pelvic floor physical therapy, myofascial trigger point release, acupuncture and electroacupuncture, psychological support and biofeedback, and electrocorporeal shockwave therapy and local thermotherapy.

The COVID-19 Residency Application Cycle Did Not Affect Geographic Dispersal Patterns Among Applicants Entering the Urology Match: A Quantitative Mapping Study

OBJECTIVE

To assess whether pandemic-related restrictions with video-based interviewing increased geographic clustering of urology applicants matching at a residency program near where they were raised or attended medical school.

MATERIALS AND METHODS

We utilized publicly available data from the urology match to compare dispersal patterns between applicants matching during the COVID-19 application cycle (2021) and those matching in the 5 prior application cycles (2016-2020). Variables included home state, undergraduate institution, medical school, and residency. Latitudes and longitudes were obtained for each institution and home state. The primary endpoint was distance (miles, as the most direct path) between medical school and residency program. We also assessed dispersal patterns by American Urological Association section.

RESULTS

Of the 1965 applicants matching to a urology program between 2016 and 2021, medical school was identified for 1956 (99.7%) applicants, undergraduate program for 1551 (79%) applicants, and home state for 1351 (69%) applicants. Comparing the COVID-19 application cycle to the 5 prior application cycles, there was no significant difference in the median distance between medical school and residency, undergraduate university and residency, or home state and residency. Similarly, there was no significant difference in the proportion of applicants matching at their home institution, matching from medical schools without a home urology program, matching from medical schools with a historically low volume of urology applicants (<1 matched applicant per year), or matching from a D.O.

PROGRAM

CONCLUSION

Virtual interviewing and the loss of in-person clinical rotations did not significantly alter dispersal patterns or hamper an applicant's ability to match at program outside their geographic region.

Testicular ultrasound underestimates the size of small testicular masses: a radiologic-pathologic correlation study

PURPOSE

Increasing use and resolution of testicular ultrasound imaging has resulted in a greater diagnosis of non-palpable small testicular masses and subsequent over-treatment with orchiectomy. Our aim was to determine the diagnostic accuracy of testicular ultrasound to accurately determine the pathologic size of small testicular masses (SMTMs) and to evaluate the association of various measurements with benign pathology.

METHODS

Retrospectively, an institutional testicular cancer database was reviewed to evaluate the patients who underwent an orchiectomy for a testicular mass seen on ultrasound from 2003 to 2017. Three-dimensional measurements were compared from the ultrasound and pathology specimens, including other measures such as tumor volume and percentage of testicular volume. Finally, the predictive accuracy of maximum diameter and tumor volume to predict benign pathology was evaluated using receiver-operating curve analysis.

RESULTS

We identified 208 patients and showed that ultrasound significantly underestimated sub-centimeter testicular masses (mean difference 0.56 cm, 95%CI 0.89-0.14, p = 0.004) and testicular masses between 1 and < 2 cm (mean difference 0.50 cm, 95%CI 0.97-0.15, p = 0.009). Tumor volume measured on ultrasound was consistently similar to pathologic tumor volume across all sizes and was significantly correlated (Spearman's Rho = 0.81). Mass volume had a greater predictive accuracy for benign pathology than maximum diameter using a 1 cm cut-off (AUC 0.65 vs 0.60).

CONCLUSION

Using the maximal diameter, testicular ultrasound significantly miscalculated the pathologic dimensions of masses less than 2 cm compared to orchiectomy specimens. Volumetric measurements may better represent actual tumor sizes for SMTMs and may be a more useful measure for identifying those a higher risk for benign pathology, however, further studies are required.

Surgical ergonomics for urologists: a practical guide

Poor ergonomics in the operating room can have detrimental effects on a surgeon's physical, psychological and economic well-being. This problem is of particular importance to urologists who are trained in nearly all operative approaches (open, laparoscopic, robotic-assisted, microscopic and endoscopic surgery), each with their own ergonomic considerations. The vast majority of urologists have experienced work-related musculoskeletal pain or injury at some point in their career, which can result in leaves of absence, medical and/or surgical treatment, burnout, changes of specialty and even early retirement. Surgical ergonomics in urology has been understudied and underemphasized. In this Review, we characterize the burden of musculoskeletal injury in urologists and focus on various ergonomic considerations relevant to the urology surgeon. Although the strength of evidence remains limited in this space, we highlight several practical recommendations stratified by operative approach that can be incorporated into practice without interrupting workflow whilst minimizing injury to the surgeon. These recommendations might also serve as the foundation for ergonomics training curricula in residency and continuing medical education programmes. With improved awareness of ergonomic principles and the sequelae of injury related to urological surgery, urologists can be more mindful of their operating room environment and identify ways of reducing their own symptoms and risk of injury.

Contemporary Assessment of the Most Cited Clinical, Basic Science, and Guidelines Papers in Urology: A Reference for Urology Journal Club

OBJECTIVE

To perform bibliometric analysis of the top cited articles in urology as a guide for journal club article selection.

METHODS

Bibliometric citation analysis was performed using Scopus. Tables illustrating the top cited clinical, basic science, and guidelines/position statements papers were constructed. Linear regression was used to determine association between h-index and number of citations.

RESULTS

A total of 3,188,861 publications from 1788 to 2020 were analyzed. The top 100 cited clinical papers from 1788 to 2020, top 100 cited contemporary clinical papers from 2000 to 2020, top 25 cited basic science papers, and the top 25 cited guidelines/position statement papers were reported. Median number of citations in the top 100 cited clinical papers was 1463 (interquartile range 1186-1821). Memorial Sloan Kettering Cancer Center (12), Johns Hopkins University (6), and Harvard University (6) contributed the most top cited clinical papers in urology. Urologic oncology was the most represented subspecialty in both clinical (75%) and basic science (96%) papers. First author and last author h-index were found to correlate with the number paper citations in the top 100 cited clinical papers from 1788 to 2020 (first author β:5.3, P= .003, last author β:4.5, P= .03). Only 7% of the most cited clinical papers in urology were from female first authors, which was not statistically significantly different from those reported in prior publications published in 2009 and 2013.

CONCLUSION

Contemporary citation analysis of indexed manuscripts in urology may serve as a valuable educational tool for urologists and trainees.

A Comparative Analysis of Surgical Scar Cosmesis Based on Operative Approach for Radical Prostatectomy

Objective: Recent developments in minimally invasive approaches to radical prostatectomy (RP) for localized prostate cancer have improved oncological outcomes, but may also affect surgical scar cosmesis, an important component of survivorship and patient quality of life. Our aim was to evaluate surgical scar appearance based on operative approach to RP using a validated tool for evaluating psychosocial impact of scar appearance. Methods: Men between the ages of 45 and 80 were surveyed on an online crowdsourcing platform. Well-healed surgical scars after open, multiport (MP) robotic (transperitoneal and extraperitoneal), and single-port (SP) robotic RP were digitally rendered on stock photos to control for patient appearance. Respondents evaluated images using the SCAR-Q© psychosocial impact domain. Additionally, different RP scars were ranked by appearance and assigned 10-point appearance scores. Results: Two hundred thirty-four surveys were included for analysis (completion rate 84.2%). The median age was 54 (IQR: 49-61) and 35% (85/234) had previous abdominal surgery, of which 45% (38/85) was robotic or laparoscopic. SP scars had better psychosocial impact scores (median 100 out of 100 vs 69 and 58) than MP and open, respectively (both p < 0.001). SP scars were consistently ranked higher by appearance (median rank 1, IQR: 1-1) than MP (2, IQR: 2-3) and open (3, IQR: 3-4) (p < 0.001). SP without assistant port had the highest appearance score (median 9, IQR: 7-9) among all scars (p < 0.001). Conclusion: SP scars scored highest on psychosocial impact and were consistently ranked highest in appearance. These findings may be informative for optimizing both cosmetic appearance and quality of life for patients undergoing RP.

Proposed Changes to the 2021 Residency Application Process in the Wake of COVID-19

The COVID-19 pandemic has brought unique challenges to the delivery of undergraduate medical education, particularly for current third-year medical students who are preparing to apply to residency. In mid-March, medical schools suspended all clinical rotations for the remainder of the 2019-2020 academic year. As such, third-year medical students may not be able to complete sufficient clinical experiences to make important career choices before they have to submit their residency applications. While the decision to suspend clinical rotations was necessary to protect students, specialty organizations and residency programs must mitigate the deficits in students' clinical education caused by the COVID-19 pandemic.In this Perspective, the authors identify potential challenges for third-year medical students and advocate for solutions to improve the residency application process for students and programs. First, they propose delaying the date that programs can access applicant data through the Electronic Residency Application Service, thereby affording students more time to complete clinical experiences, solidify their specialty decision, and strengthen their residency application. Second, the authors recommend a restriction on the number of visiting rotations that students are expected to complete to allow for a more equitable distribution of these important experiences. Third, they suggest that program directors from each specialty agree on a maximum number of applications per applicant (based on historical data) to curb an upsurge in applications that may stem from the unique circumstances created by COVID-19 without causing applicants undue stress. Lastly, the authors advocate that residency programs develop infrastructure to conduct video-based interviews and engage students through virtual networking events.Amidst the unique environment created by COVID-19, the authors urge governing bodies, specialty organizations, and residency programs to consider these recommendations to improve the efficiency and reduce the stress surrounding the 2021 Match.

Drug delivery options and therapeutic advances in the management of erectile dysfunction

INTRODUCTION

Erectile dysfunction (ED) is defined as the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It is estimated that 20-30% of adult men will have at least one episode of ED during their lifetime and the prevalence increases with age. ED is known to have significant negative psychological implications for men, resulting in impaired functional status and a greater prevalence of anxiety and depression.

AREAS COVERED

Medications for the treatment of erectile dysfunction largely revolve around oral, injection, and topical therapies. Though all three modalities are widely used, each delivery option has its own advantages and specific indications. Likewise, there are several new developing treatments for ED that may change the landscape of treatment. The goal of this review is to summarize contemporary drug delivery options used in the treatment of ED and highlight future promising pharmacological developments.

EXPERT OPINION

There are a myriad of new developments on the horizon including new PDE5Is and drug targets, nanotechnology enhancements, stem cell and gene therapy, shockwave therapy, and platelet-rich plasma injections. These are all promising new methods to not only treat ED but also to address the pathology and prevent or eliminate further damage.

Management of acute post-operative hemorrhage following partial nephrectomy with renal artery embolization

Hemorrhage after robotic-assisted partial nephrectomy (RAPN) is uncommon but can cause significant morbidity. We present a case of acute hemorrhage isolated to the collecting system that was managed with renal artery embolization (RAE).

A 76-year-old male developed sudden onset transfusion-dependent hematuria and hypotension following uncomplicated RAPN. He had no signs of intra-abdominal bleeding and his hypotension was responsive to volume resuscitation. Renal angiography identified a segmental artery with extravasation into the collecting system. RAE eliminated the patient's hematuria, the need for further transfusion, and allowed preservation of renal function. RAE is a viable option for collecting system hemorrhage following RAPN.

Low-intensity extracorporeal shockwave therapy in the treatment of erectile dysfunction following radical prostatectomy: a critical review

Low-intensity extracorporeal shockwave therapy (LI-ESWT) to the penis has recently emerged as novel therapeutic option in the treatment of erectile dysfunction (ED). Randomized-controlled studies investigating the effect of this new treatment modality revealed promising results in men with vasculogenic ED. However, the efficacy of LI-ESWT in men who develop ED following radical prostatectomy (RP) remains obscure due to the exclusion of this group in nearly all clinical trials. In this review, the authors synthesize the findings from available preclinical and clinical studies that examine the potential utility of LI-ESWT in men with post-RP ED.

Rethinking active surveillance for prostate cancer in African American men

Active surveillance (AS) is a treatment modality for prostate cancer that aims to simultaneously avoid overtreatment and allow for the timely intervention of localized disease. AS has become the de facto standard of care for most men with low-risk prostate cancer. However, few African American (AA) men were included in the prospective observational cohorts that resulted in a paradigm shift in treatment recommendations from active intervention toward AS. It has been established that AA men have an increased prostate cancer incidence, higher baseline prostate-specific antigen (PSA) values, more aggressive prostate cancer features, greater frequency of biochemical recurrence after treatment, and higher overall cancer-specific mortality compared to their Caucasian counterparts. As such, this has given many physicians pause before initiating AS for AA patients. In the following manuscript, we will review the available literature regarding AS, with a particular focus on AA men. The preponderance of evidence demonstrates that AS is as viable a management method for AA with low-risk prostate cancer as it is with other racial groups.

Penile Prosthesis Complications: Planning, Prevention, and Decision Making

INTRODUCTION

Inflatable penile prosthesis (IPP) is an established treatment option for men with erectile dysfunction (ED) refractory to medical therapy. Standardization of surgical technique and improvements in device construction have reduced all-cause complication rates to less than 5% in recent reports. Nonetheless, complications do exist, and can strongly impact morbidity and the quality of life of patients. Prosthetic urologists must be aware of the constellation of complications that can arise during or after IPP placement.

AIM

To provide a comprehensive review of penile prosthesis complications and discuss preventative strategies, as well as proper preoperative, intraoperative, and postoperative decision making.

METHODS

A review of the available literature from 1973 to 2018 was performed using PubMed with regard to IPP complications.

MAIN OUTCOME MEASURES

We reviewed publications that outlined preoperative planning strategies and the following IPP complications: hematoma, floppy glans, corporal fibrosis, corporal perforation and crossover, urethral injury, infection, impending erosion, and glandular ischemia.

RESULTS

Careful patient and device selection, setting realistic expectations of postsurgical outcomes, and adherence to a perioperative checklist is essential in the preoperative period. Intraoperatively, anticipate corporal fibrosis situations and always dilate laterally during corporal passage to reduce the risk of crossover and urethral injury. Limit perioperative antiplatelet therapy, apply compressive dressing, use a closed suction drain if indicated, and leave the device partially inflated postoperatively to reduce risk of hematoma. After surgery, monitor patients for potential complications that may warrant device explantation or salvage: IPP infection, glans ischemia, and impending erosion.

CONCLUSIONS

By using evidence and expert opinion-based decision-making strategies in the preoperative, intraoperative, and postoperative period of IPP placement, surgeons can reduce the risk of complications and dissatisfaction, even in ED patients with multiple comorbid conditions.

Role of Penile Prosthesis in Priapism: A Review

Ischemic priapism is a urological emergency that has been associated with long-standing and irreversible adverse effects on erectile function. Studies have demonstrated a linear relationship between the duration of critically ischemic episodes and the subsequent development of corporal fibrosis and irreversible erectile function loss. Placement of a penile prosthesis is a well-established therapeutic option for the management of erectile dysfunction secondary to ischemic priapism, and will be the focus of this review. Review of the current literature demonstrates a growing utilization of penile prostheses in the treatment of erectile dysfunction secondary to ischemic priapism. Unfortunately, there is a paucity of randomized-controlled trials describing the use of prosthesis in ischemic priapism. As a result, there is a lack of consensus regarding the type of prosthesis (malleable vs. inflatable), timing of surgery (acute vs. delayed), and anticipated complications for each approach. Both types of prostheses yielded comparable complication rates, but the inflatable penile prosthesis have higher satisfaction rates. Acute treatment of priapism was associated with increased risk of prosthetic infection, and could potentially cause psychological trauma, whereas delayed implantation was associated with greater corporal fibrosis, loss of penile length, and increased technical difficulty of implantation. The paucity of high-level evidence fuels the ongoing discussion of optimal use and timing of penile prosthesis implantation. Current guidance is based on consensus expert opinion derived from small, retrospective studies. Until more robust data is available, a patient-centered approach and joint decision-making between the patient and his urologist is recommended.

Post-Orgasmic Illness Syndrome: A Review

INTRODUCTION

Post-orgasmic illness syndrome (POIS) is a rare but debilitating cluster of postejaculatory symptoms affecting men. It is a chronic disorder manifesting as a constellation of flulike and allergic symptoms within seconds, minutes, or hours after ejaculation. POIS can be followed by mental sequelae such as diminished concentration and irritability. POIS negatively affects the life of patients by limiting sexual encounters, dampening romantic prospects, creating internal struggles to avoid eroticism, and affecting patients' schedules. First described in 2002, the prevalence and incidence of POIS are still unknown owing to a paucity of studies but is likely under-reported. There are approximately 50 cases of POIS in the literature. Despite the debilitating effects of POIS, the pathophysiology of POIS is still not well elucidated.

AIM

To provide an update on the current literature on POIS, provide updated information on the pathophysiology of POIS, and discuss potential management options.

METHODS

Comprehensive review of literature pertaining to POIS.

MAIN OUTCOME MEASURES

The symptoms, classification, pathophysiology, diagnostic considerations, and management of POIS were reviewed.

RESULTS

There are 5 preliminary diagnostic criteria for diagnosing this condition. POIS is categorized as primary or secondary. The autoimmune-allergy hypothesis is the most accepted hypothesis explaining the pathogenesis of POIS. A competing hypothesis involves a disorder involving endogenous μ-opioid receptors. Another hypothesis invokes impairment of the cytokine and neuroendocrine responses. There are no known treatment modalities for POIS; patients have been symptomatically treated with antihistamines, selective serotonin reuptake inhibitors, and benzodiazepines. A trial of hyposensitization therapy with autologous semen was successful. A trial of non-steroidal anti-inflammatory medication helped 1 patient described in a single case report, but failed to successfully treat other patients.

CONCLUSIONS

POIS is a rare condition that is underdiagnosed and under-reported. Further studies are warranted to investigate the prevalence, pathophysiology, and treatment of this debilitating condition.

Collagenase Clostridium Histolyticum in the Treatment of Peyronie's Disease: Review of a Minimally Invasive Treatment Option

Peyronie's disease (PD) is an inflammatory disorder characterized by an abnormal collagen deposition in the tunica albuginea of the penis, leading to fibrous and non-compliant plaques that can impede normal erection. Although pharmacological treatments are available, only intralesional injection therapy and surgical reconstruction have demonstrated tangible clinical efficacy in the management of this condition. Intralesional injection of collagenase clostridium histolyticum (CCH) has come to the forefront of minimally invasive treatment of PD. In this review, the authors provide an update on the safety, efficacy, and indications for CCH. The efficacy of CCH will be assessed on the basis of improvement in the severity of penile fibrosis, curvature, and pain. Numerous well-designed clinical trials and post-approval studies involving more than 1,500 patients have consistently demonstrated the efficacy and tolerability of CCH in the treatment of PD. CCH significantly decreases penile curvature and plaque consistency, as well as improves quality of life. Post-approval studies continue to demonstrate the efficacy of CCH despite broader inclusion criteria for treatment, such as the case with acute phase disease and atypical plaque deformities (i.e., ventral plaques, hourglass narrowing). CCH continues to be the gold standard for non-surgical management of stable phase PD, in the absence of strong evidence supporting oral therapy agents and ongoing evaluation of extracorporeal shockwave therapy. However, recent studies are beginning to provide precedent for the use of CCH in the management of acute phase and atypical PD.

Erectile Dysfunction in Young Men-A Review of the Prevalence and Risk Factors

INTRODUCTION

Erectile dysfunction (ED) is an important health concern that can significantly affect a man's psychosocial well-being. ED has traditionally been considered a disease of old age; however, contemporary evidence suggests a growing incidence of ED in men younger than 40 years. The process of achieving an erection is multifaceted; there are many potential mechanisms that can be disrupted. It is critical to identify the specific causes of ED before proceeding with potentially costly and invasive therapeutic options. Advances in diagnostic and treatment modalities offer opportunities to identify and manage young men with ED.

AIM

To provide an update on the prevalence and risk factors of ED in young men and to provide a framework to guide clinicians in identifying and managing the affected young man.

METHODS

Comprehensive review of the literature pertaining to ED in young men.

MAIN OUTCOME MEASURES

ED in young men was assessed by outlining the prevalence according to recent epidemiologic studies. The pathophysiology, diagnostic considerations, risk factors, and etiologies were reviewed.

RESULTS

Large multinational studies have estimated the prevalence of ED in young men to be as high as 30%. Several studies have stratified the etiologies of ED into psychogenic and organic causes. Psychogenic etiologies of ED include depression, anxiety, and partner-related difficulties. These patients tend to experience sudden onset of symptoms, with decreased libido and good quality of spontaneous or self-stimulated erections. Organic etiologies include vasculogenic, endocrinologic, neurogenic, iatrogenic, and structural components. These patients usually experience gradual onset of symptoms and a low to normal libido. Conservative treatments such as phosphodiesterase type 5 inhibitors continue to be the mainstay treatment.

CONCLUSIONS

ED in young men is an increasingly common condition. A careful diagnostic evaluation should focus on the identification of any underlying etiology to ensure appropriate management of patients.
