Pudendal nerve block decreases narcotic requirements and time spent in post-anesthesia care units in patients undergoing primary inflatable penile prosthesis implantation

Efforts to minimize narcotic usage following inflatable penile prosthesis (IPP) implantation are vital, considering the current opioid epidemic in the United States. We aimed to determine whether pudendal nerve block (PNB) utilization in a multiethnic population undergoing primary IPP implantation can decrease rates of post-operative opiate usage. A single-institution, retrospective study was conducted on patients who underwent primary IPP implantation between December 2015 and June 2022. PNB usage and intra- and post-operative outcomes were analyzed using multivariate binary logistic regression. 449 patients were included, with 373 (83.1%) in the PNB group. Median time (minutes) spent in the post-anesthesia care unit (PACU) (1499 [119-198] vs. 235 [169-322], p < 0.001) was significantly lower in the PNB group. There were no significant differences in intra-operative and PACU morphine milligram equivalents or post-operative safety outcomes between groups. However, fewer patients in the PNB group called for pain medications post-operatively (10.2% vs 19.7%, p = 0.019). Multivariate analysis revealed a significantly decreased operative time (B -6.23; 95%CI -11.28, -1.17; p = 0.016) and decreased time in recovery (B: -81.62; 95%CI: -106.49, -56.76, p < 0.001) in the PNB group. PNB decreases post-operative opioid analgesic requirements and time spent in PACU in patients undergoing a primary IPP implantation and thus may represent an attractive, non-opioid adjunct.

Minimally invasive surgical therapies for benign prostatic hyperplasia in the geriatric population: A systematic review

BACKGROUND

Geriatric patients, prone to adverse events (AEs) and low compliance with drugs, may benefit from minimally invasive surgical therapies (MISTs) for managing benign prostatic hyperplasia (BPH). We evaluated the efficacy, safety, and procedural characteristics of MISTs in geriatric patients with BPH.

METHODS

PubMed/MEDLINE database was systematically searched for relevant articles through October 1, 2023. Eligible studies focused on geriatric patients (≥65 years) with BPH who were treated with MISTs and evaluated follow-up surgical, micturition, and/or sexual outcomes. Studies were included if there was separate reporting for age subgroups ≥65 years, or if the mean age minus standard deviation was ≥65 years, or if the first quartile was ≥65 years.

RESULTS

Out of 292 screened studies, 32 (N = 3972 patients) met inclusion criteria and assessed prostatic artery embolization (PAE), Rezum, GreenLight, holmium laser enucleation of the prostate (HoLEP), thulium laser enucleation of the prostate (ThuLEP), diode laser enucleation of the prostate (DiLEP), and Aquablation. Except for Rezum, all MISTs required a planned overnight stay. While PAE and Rezum could be performed under local anesthesia, the other MISTs needed general or spinal anesthesia. Postoperative catheterization duration was longest for PAE (median 14 days) and Rezum (21 days) and shortest for GreenLight (1.9 days). At 12 months postoperatively, all MISTs exhibited significant percent changes in International Prostate Symptom Score (median -69.9%) and quality of life (median -72.5%). Clavien-Dindo Grade 1 AEs ranged widely, with PAE (5.8%-36.8%), Rezum (0%-62.1%), and GreenLight (0%-67.6%) having the largest range, and HoLEP (0%-9.5%), ThuLEP (2%-6.9%), and DiLEP (5%-17.5%) having the smallest. PAE, Rezum, DiLEP, and Aquablation reported no significant changes in the International Index of Erectile Function.

CONCLUSIONS

Although all the MISTs reviewed in this study effectively treat BPH in geriatric patients, differences in procedural characteristics and safety profiles across MISTs were considerable. Physicians should use shared decision-making processes, considering risks and patient characteristics, when choosing a suitable treatment option for their patients.

Testosterone deficiency in men with end stage renal disease and kidney transplantation: a narrative review

Testosterone deficiency is a prevalent condition that frequently affects individuals with end-stage renal disease (ESRD) and those who have undergone renal transplantation. While the etiology of this condition is complex, its implications in this population are far-reaching, impacting various domains such as endocrine profile, sexual and erectile function, bone mineral density (BMD), anemia, and graft survival following renal transplantation. Herein, we review the most recent literature exploring the pathophysiology of testosterone deficiency in ESRD and renal transplant patients, examining its diverse effects on this demographic, and assessing the advantages of testosterone replacement therapy (TRT). Existing evidence suggests that TRT is a safe intervention in ESRD and renal transplant patients, demonstrating improvements across multiple domains. Despite valuable insights from numerous studies, a critical need persists for larger, high-quality prospective studies to comprehensively grasp the nuances of TRT, especially in this vulnerable population. Proactive screening and treatment of testosterone deficiency may prove beneficial, emphasizing the urgency for further research in this area.

A survey of exposure to the use of Xiaflex for the treatment of Peyronie's disease among United States urology residency programs

Xiaflex® (collagenase clostridium histolyticum) is a Food and Drug Administration-approved treatment for patients with Peyronie's disease. Despite its approval and implementation, there is concern that urologists in training are offered minimal exposure to its use. Thus, the purpose of this study was to evaluate the exposure of urology residents to Peyronie's disease and its management, particularly Xiaflex®. A Google Forms survey regarding the exposure of residents to Peyronie's disease and use of Xiaflex® was created and disseminated through email to urology programs. Overall, 47 institutional responses were received. At 45 institutions (95.7%), residents receive training in directly evaluating and caring for patients with Peyronie's disease. At 46 institutions (97.9%), residents receive training in observing and/or performing surgical procedures for Peyronie's disease. Residents at 31 institutions (66.0%) receive observational or procedural training for non-surgical management of Peyronie's disease, specifically Xiaflex®. Residents receive non-surgical training from an academic faculty who is fellowship trained in sexual medicine at 25 institutions and an academic faculty not trained in sexual medicine at six institutions. There exists a glaring disparity in residency exposure to Xiaflex®. Further research is warranted to elucidate how programs can provide residents with further exposure to the use of Xiaflex® in patients with Peyronie's disease.

A primer on the restorative therapies for erectile dysfunction: a narrative review

INTRODUCTION

Erectile dysfunction (ED) is a common condition that affects millions worldwide. Patients and urologists alike are seeking alternative therapies that can provide long-lasting results in the treatment of ED. This review provides a comprehensive overview of restorative treatments available for ED, such as platelet-rich plasma, stem cell therapy, and shockwave therapy.

OBJECTIVE

The aim of this narrative review is to provide a primer for urologists and general practitioners on the basics of implementing ED restorative therapies in their practice.

METHODS

The PubMed, MEDLINE, and Google Scholar databases were searched for articles in the English language through August 31, 2023, that included key terms such as "erectile dysfunction," "restorative therapy," "shockwave therapy," "platelet-rich plasma," "stem cell therapy," and "stromal vascular fraction." Reference lists of selected studies were manually reviewed to find articles not identified by the initial database search.

RESULTS

Shockwave therapy has demonstrated effectiveness in treating ED, with devices like the Medispec ED1000 and Storz Duolith showing statistically significant improvements in patient scores for International Index of Erectile Function (IIEF)-Erectile Function scores in clinical trials. In reported studies of platelet-rich plasma injections, a substantial percentage of patients reached a minimal clinically important difference in the IIEF-Erectile Function scale after treatment. Studies of ED treatment with stem cell therapy, while limited and with small sample sizes, have demonstrated encouraging improvements in patient scores for the abridged 5-item version of the IIEF after treatment.

CONCLUSION

Shockwave, platelet-rich plasma, and stem cell therapies are important, novel, noninvasive restorative treatments for ED that can provide relief for patients wishing to avoid a more invasive approach. While these therapies have shown promising results in clinical trials, more research is required to establish them as standardized and efficacious options in the management of ED.

Real-world four-year functional and surgical outcomes of Rezum therapy in younger versus elderly men

BACKGROUND

Management of urinary symptoms in elderly patients with benign prostatic hyperplasia (BPH) is complex given challenges with medications and invasive surgeries. Rezum, a minimally invasive water vapor therapy, is an emerging alternative. We compare real-world Rezum outcomes between young and elderly patients over 4 years.

METHODS

We retrospectively analyzed a multiethnic population treated with Rezum at a single center between 2017-2019. Patients were stratified into young (<65 years) or elderly (≥65 years) cohorts. International Prostate Symptom Score (IPSS), Quality of Life (QoL), maximum urinary flow rate (Qmax), decisional regret scores, and adverse events (AEs) were assessed at baseline, 1-, 3-, 6-, 12-, and/or 48-months. Descriptive statistics were compared using t-tests, Chi-squared, or Mann-Whitney U tests. Changes in outcomes were assessed using Wilcoxon signed-rank tests, stratified by age.

RESULTS

256 patients - 146 (57%) young and 110 (43%) elderly - were included. The majority were Asian (33.2%) or non-Hispanic Black (28.9%). Significant improvements were observed in the combined cohort at 4-years in IPSS, QoL, and Qmax when compared to baseline (all p < 0.05). Between the age cohorts, there were no significant differences in IPSS, QoL, or Qmax at any follow-up. Within both cohorts, significant improvements in IPSS and QoL were found from baseline to all follow-ups. In the young cohort, Qmax was significantly improved from baseline to all follow-ups while in the elderly cohort, this was observed only at the 3-month follow-up. No significant differences in AEs or regret was found between cohorts. There was no significant difference in 4-year surgical retreatment rates between cohorts (elderly 4.0% vs young 4.4%, p = 0.86).

CONCLUSIONS

There were no significant differences in IPSS, QoL, or AEs between elderly and younger men over 4 years following Rezum, suggesting comparable benefits and risks. Future research is warranted to clarify the impact of Rezum on Qmax in elderly men.

Performance of cognitive vs. image-guided fusion biopsy for detection of overall and clinically significant prostate cancer in a multiethnic population

PURPOSE

Transrectal ultrasound-guided prostate biopsy remains the most used method for the detection of prostate cancer. We recently reported that detection of clinically significant prostate cancer (cs-CaP) using image-guided fusion biopsies (IGFB) varied by race/ethnicity, which calls for further comparison between cognitive fusion biopsy (CFB) and IGFB among non-Hispanic black and Hispanic populations. Therefore, the aim of our study is to compare the rates of detection of cs-CaP and overall CaP by CFB and IGFB in a multiethnic community.

MATERIAL AND METHODS

We performed a retrospective, cross-sectional review of men who underwent MRI-transrectal ultrasound-guided prostate biopsy at our diverse, urban academic medical center. Agreement and discordance between fusion biopsies and systematic biopsies for detection of cs-CaP and overall CaP were determined using Kappa statistics. Univariate and multivariate mixed-effects logistic regression models were used to find associations between fusion modalities and prostate cancer detection.

RESULTS

In total, 710 men underwent fusion prostate biopsies between December 2015 and June 2021. Upon univariate and multivariate logistic regression analysis, there was no significant association between IGFB vs. CFB and risk of overall CaP (OR = 0.66, 95% CI: 0.36-1.21, P = 0.18) or cs-CaP (OR = 0.57, 95% CI: 0.30-1.08, P = 0.09). We found moderate agreement between fusion and systematic biopsies for both CFB (κ = 0.56) and IGFB (κ = 0.52) in cs-CaP.

CONCLUSIONS

CFB and IGFB offer similar detection rates of cs-CaP in a multiethnic population. CFB represents an effective and accessible means of accurately diagnosing prostate cancer.

Temporal Trends of Semen Quality and Fertility Rates Over the Course of a Decade: Data From King County, Washington

OBJECTIVE

There has been a widely reported decline in both semen quality and fertility rate, however to date these studies have not looked at a decline of both in the same time period within the same geographical area. The objective of this study was to determine if there existed a temporal trend in both semen parameters and fertility rates for the same geographic area (King County, WA) over time.

MATERIALS AND METHODS

Semen parameters from sperm donors at Seattle sperm bank were obtained from 2008 to 2021. Sperm donations occurred in King County, WA. Donors were from within 50 miles of the donation site. Fertility rates were calculated for King County, WA using census data from SEER to find number of women aged 15-49 and the number of births were found using CDC Wonder data from 2006 to 2017.

RESULTS

There were a total of 76,622 sperm donor semen analyses from King County, WA included in our study from 2008 to 2021. The fertility rate for King County, WA was calculated from 2006 to 2017. From 2008 to 2021, there was a statistically significant decline in semen quality over time for both sperm count (P < .01), total motile sperm count (P < .01), sperm concentration (P < .01), and progressive motility (P < .01). Additionally, from 2006 to 2017 there was a statistically significant decline in fertility rate (P < .01).

CONCLUSION

We report a statistically significant decline in sperm parameters among donors and a corresponding decline in fertility rates from the same geographic area that warrants further investigation given the serious societal and economic impacts a shrinking population presents. While certainly not the sole contributing factor, declining sperm parameters likely need to be accounted for when accounting for declining fertility rates.

Implementation of a shared research database to increase medical student awareness and involvement in urology research A pilot study

INTRODUCTION

We aimed to assess the effect of a shared institutional research database on medical students' scholarly work, perceived research competency, and self-reported satisfaction.

METHODS

An institutional inventory database was created on Google Sheets with a listing of available mentors and a description of their ongoing research projects. The inventory database was shared with interested students and faculty. Students who agreed to participate were surveyed pre- and post-inventory. Survey questions assessed student demographics, prior research experience, and their perception of research competency and satisfaction. The number of presentations, publications, and articles pre- and post-inventory were also abstracted. Survey responses were compared using the Mann-Whitney U test.

RESULTS

A total of 20 students were surveyed pre-inventory and at a median followup of six months (5-7) post-inventory. There was a significant increase in scholarly presentations and publications post-inventory (p<0.05 for all). Furthermore, post-inventory, students reported feeling more confident in establishing an academic career, finding good mentors, managing their relationship with their mentor, managing professional challenges, and effectively showcasing themselves professionally and describing their research (p<0.05 for all). More than 65% of students agreed or strongly agreed that the database was easy to use, accessible, transparent, and would like a similar database created for other specialty departments.

CONCLUSIONS

After performing mentorship-guided research through an institutional research database, medical students felt more confident in their ability to perform research and produced more scholarly work. Therefore, we recommend a research database be created across all institutional departments to foster interest in conducting research.

Electronic Health Record Usage Patterns Across Surgical Subspecialties

OBJECTIVES

This study aimed to utilize metrics from physician action logs to analyze surgeon clinical, volume, electronic health record (EHR) efficiency, EHR proficiency, and workload outside scheduled time as impacted by physician characteristics such as years of experience, gender, subspecialty, academic title, and administrative title.

METHODS

We selected 30 metrics from Epic Signal, an analytic tool in Epic that extracts metrics related to clinician documentation. Metrics measuring appointments, messages, and scheduled hours per day were used as a correlate for volume. EHR efficiency, and proficiency were measured by scores built into Epic Signal. Metrics measuring time spent in the EHR outside working hours were used as a correlate for documentation burden. We analyzed these metrics among surgeons at our institution across 4 months and correlated them with physician characteristics.

RESULTS

Analysis of 133 surgeons showed that, when stratified by gender, female surgeons had significantly higher EHR metrics for time per day, time per appointment, and documentation burden, and significantly lower EHR metrics for efficiency when compared to male surgeons. When stratified by experience, surgeons with 0 to 5 years of experience had significantly lower EHR metrics for volume, time per day, efficiency, and proficiency when compared to surgeons with 6 to 10 and more than 10 years of experience. On multivariate analysis, having over 10 years of experience was an independent predictor of more appointments per day, greater proficiency, and spending less time per completed message. Female gender was an independent predictor of spending more time in notes per appointment and time spent in the EHR outside working hours.

CONCLUSION

The burden associated with volume, proficiency, efficiency, and workload outside scheduled time related to EHR use varies by gender and years of experience in our cohort of surgeons. Evaluation of physician action logs could help identify those at higher risk of burnout due to burdensome medical documentation.

Male obesity: Associated effects on fertility and the outcomes of offspring

Obesity rates are increasing globally, making it imperative to comprehend the effects of parental obesity on human reproduction. This review aims to highlight the impact of male obesity on reproductive and offspring outcomes. Male obesity has been shown to affect fertility through various mechanisms, including changes in semen quality, difficulty with natural conception, and worsened assisted reproductive technology outcomes. The evidence regarding the impact of male obesity on success of sperm retrieval is conflicting, but all aforementioned adverse effects may be modifiable with weight loss. Moreover, paternal obesity may influence atypical offspring outcomes, such as placental abnormalities and disruptions in fetal development, which may be moderated by epigenetic pathways. Further research is needed to fully understand the complex relationships and underlying mechanisms involved. Gaining more insight into the impact of male obesity on fertility and offspring outcomes can aid in the development of targeted interventions to improve family planning and the health of future generations.

ChatGPT's Ability to Assess Quality and Readability of Online Medical Information: Evidence From a Cross-Sectional Study

Introduction Artificial Intelligence (AI) platforms have gained widespread attention for their distinct ability to generate automated responses to various prompts. However, its role in assessing the quality and readability of a provided text remains unclear. Thus, the purpose of this study is to evaluate the proficiency of the conversational generative pre-trained transformer (ChatGPT) in utilizing the DISCERN tool to evaluate the quality of online content regarding shock wave therapy for erectile dysfunction. Methods Websites were generated using a Google search of "shock wave therapy for erectile dysfunction" with location filters disabled. Readability was analyzed using Readable software (Readable.com, Horsham, United Kingdom). Quality was assessed independently by three reviewers using the DISCERN tool. The same plain text files collected were inputted into ChatGPT to determine whether they produced comparable metrics for readability and quality. Results The study results revealed a notable disparity between ChatGPT's readability assessment and that obtained from a reliable tool, Readable.com (p<0.05). This indicates a lack of alignment between ChatGPT's algorithm and that of established tools, such as Readable.com. Similarly, the DISCERN score generated by ChatGPT differed significantly from the scores generated manually by human evaluators (p<0.05), suggesting that ChatGPT may not be capable of accurately identifying poor-quality information sources regarding shock wave therapy as a treatment for erectile dysfunction. Conclusion ChatGPT's evaluation of the quality and readability of online text regarding shockwave therapy for erectile dysfunction differs from that of human raters and trusted tools. Therefore, ChatGPT's current capabilities were not sufficient for reliably assessing the quality and readability of textual content. Further research is needed to elucidate the role of AI in the objective evaluation of online medical content in other fields. Continued development in AI and incorporation of tools such as DISCERN into AI software may enhance the way patients navigate the web in search of high-quality medical content in the future.

Should Men Eat More Plants? A Systematic Review of the Literature on the Effect of Plant-Forward Diets on Men's Health

OBJECTIVE

To perform a systematic review of the literature on plant-based and plant-forward diets and the prevention/treatment of the following common men's health conditions: prostate cancer (PCa), erectile dysfunction (ED), and benign prostatic hyperplasia (BPH).

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses system criteria were utilized to search PubMed and Medline databases for the following search terms: "Diet (Mesh)" OR "Diet Therapy (Mesh)" AND "Prostatic Hyperplasia (Mesh)" OR "Prostatic Neoplasm (Mesh)" OR "Erectile Dysfunction (Mesh)." Articles in English published from 1989 to 2022 using human participants were analyzed, data summarized, and assessed for bias.

RESULTS

Studies reporting on plant-based or vegetable-forward diets (Mediterranean) as an intervention were included. Cohort and cross-sectional studies using food frequency questionnaires or diet classification indices to quantify plant-based food intake patterns were included in the study. Ultimately, 12 PCa articles, 4 BPH articles, 6 ED articles, and 2 articles related to both BPH and ED were reviewed. Overall, the literature suggests plant-forward diets confer a protective effect on the men's health conditions reviewed.

CONCLUSIONS

Evaluation of the literature on the impact of plant-forward diets on urologic conditions includes a heterogenous range of dietary patterns and study designs. The greatest amount of research has evaluated the application of plant-forward diets for PCa. While there is currently a lack of high-quality evidence for the use of plant-forward diets as prevention and/or treatment for PCa, ED, or BPH, reported outcomes suggest a consistent small beneficial impact alongside well-established benefits for common chronic conditions.

Efficacy and safety of the Rezum system for the treatment of catheter-dependent urinary retention: Three-year real-world outcomes in a multimorbid, multiethnic population

OBJECTIVES

To evaluate the long-term real-world efficacy and safety of Rezum for the treatment of catheter-dependent urinary retention in a multimorbid, multiethnic population.

METHODS

A single-office, retrospective study was conducted on patients treated with Rezum between 2017 and 2019. Patients were included if they had catheter-dependent urinary retention prior to treatment and at least one follow-up within 36 months postoperatively. Patient demographics, procedural characteristics, adverse events (AEs), and outcome measures, including benign prostate hyperplasia (BPH) medication usage and postvoid residual (PVR), were collected at 3, 6, 12, and/or 36 months postoperatively. Regret was assessed at 36 months using the 5-item Decisional Regret Scale (DRS).

RESULTS

A total of 27 patients met the inclusion criteria, with the majority being Asian (29.6%), followed by non-Hispanic Black (26.0%) and Hispanic (22.2%). Most patients (77.8%) had at least one comorbidity. Trial of void (TOV) was attempted at a median of 8 days (7, 13). Fourteen patients (51.9%) failed their initial TOV. Median time until catheter independence was 13.5 days (8.5, 28.8). Common AEs included urinary retention (51.9%), urinary tract infections (UTIs) (25.9%), and dysuria (25.9%). All cases of UTIs (7/7) and most cases of dysuria (6/7) occurred in patients who failed their initial TOV. At 36 months, there was a significant median percentage change in PVR (-100.0% [-100.0, -36.7], p = .049), and 40.4% of patients discontinued their BPH medications (p = .001). Of the 11 patients who filled out the DRS, 10 (90.9%) agreed/strongly agreed that they made the right decision. By 36 months, 4 patients (14.8%) underwent reoperation and 24 (88.9%) remained catheter-independent.

CONCLUSIONS

At long-term follow-up, Rezum effectively treated catheter-dependent urinary retention with minimal decisional regret. In patients with urinary retention, urologists should consider delaying TOV until 2 weeks postoperatively to maximize the likelihood of a successful TOV and minimize the risk of AEs.

Rezum water vapor therapy for patients with mild, moderate, or severe lower urinary tract symptoms: A retrospective study in a multiethnic population

BACKGROUND

The Rezum System (Rezum) represents a novel, minimally invasive surgical therapy used to treat lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). We evaluated the safety and efficacy of Rezum in patients with mild, moderate, or severe LUTS.

METHODS

A single office, retrospective study was conducted on patients from a multiethnic population treated with Rezum between 2017 and 2019. Patients were categorized into three cohorts based on baseline International Prostate Symptom Score (IPSS) LUTS severity: mild LUTS (IPSS ≤ 7), moderate LUTS (IPSS 8-19), or severe LUTS (IPSS ≥ 20) cohorts. Outcome measures, including IPSS, quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), BPH medication usage, and adverse events (AEs) were collected and analyzed at baseline, 1-, 3-, 6-, and/or 12-months postoperatively.

RESULTS

A total of 238 patients were included: 33 with mild LUTS, 109 with moderate LUTS, and 96 with severe LUTS. At 1-month follow-up, the moderate and severe LUTS cohorts saw significant improvements in IPSS (moderate LUTS: -3.0 [-6.0, 1.5], p < 0.001; severe LUTS: -10.0 [-16.0, -5.0], p < 0.001) and QoL (moderate LUTS: -1.0 [-3.0, 0.0], p < 0.001; severe LUTS: -1.0 [-3.0, 0.0], p < 0.001) and improvements remained durable up to 12-months (p < 0.001). The mild LUTS cohort saw significant worsening in IPSS by 2.0 (0.0, 12.0) at 1-month (p = 0.002) but returned to baseline at 3-months (p = 0.114). However, the mild LUTS cohort experienced significant improvements in QoL by -0.5 (-3.0, 0.0) at 3-months (p = 0.035) and nocturia by 0.0 (-1.0, 0.0) at 6-months (p = 0.002), both of which remained durable to 12-months (p < 0.05). Most AEs were transient and nonserious, with gross hematuria (66.5%) being most common. There were no significant differences in QoL point reduction, Qmax improvement, PVR reduction, and AE occurrence between the cohorts at 12-months (p > 0.05). At 12-months, 80.0%, 87.5%, and 66.0% of the patients in the mild, moderate, and severe LUTS cohorts discontinued their BPH medications, respectively.

CONCLUSIONS

Rezum provides rapid and durable relief in LUTS in patients with moderate or severe LUTS and can be offered to patients with mild LUTS who have bothersome nocturia and wish to discontinue their BPH medications.

Prevalence of secondary erythrocytosis in men receiving testosterone therapy: A matched-cohort analysis of intranasal gel, injections, and pellets

INTRODUCTION

Increased hematocrit (HCT) is a common adverse effect in men on testosterone therapy (TTh). We aimed to uncover differences in HCT changes among men receiving different forms of TTh, namely intranasal gels, intramuscular injections, and subcutaneous pellets.

METHODS

We conducted a single-center, retrospective, matched-cohort study of patients treated for testosterone deficiency (TD) to investigate the effect of three TTh regimens on HCT. We included men who received intranasal testosterone (NT), intramuscular testosterone (TC), or subcutaneous testosterone pellet (TP) regimens between January 2011 and December 2020. We matched treatment cohorts 1:1:1 for age, body mass index (BMI), and history of obstructive sleep apnea. Those taking TTh for less than 16 weeks were excluded. Comparison between groups was performed with U-Mann Whitney test, Student t-test, ANOVA, or Kruskal Wallis test as appropriate.

RESULTS

Seventy-eight matched-cohort individuals with testosterone deficiency (TD) received either NT, TC, or TP. The most common TD symptoms prior to initiation of TTh were erectile dysfunction (38%), low libido (22%), and lack of energy (17%). Baseline serum testosterone and HCT were higher in NT (p<0.05) recipients. As expected, all men receiving TTh were found to have increased serum testosterone levels at followup (p<0.001). Relative to their respective baselines, men receiving TC experienced the greatest increase in serum testosterone (240.8 ng/dL to 585.5 ng/dL), followed by NT (230.3 ng/dL to 493.5 ng/dL) and TP (210.8 ng/dL to 360.5 ng/dL) (all p<0.001). TC and TP were associated with significant increases in HCT (4.4% and 1.7%), while NT was associated with a decrease in HCT (-0.8%) at 16-week followup.

CONCLUSIONS

When controlled for age, BMI, and OSA, men receiving NT experienced decreased HCT compared to TC or TP at 16-week followup. Intranasal testosterone, while able to increase serum testosterone levels to reference range, does not appear to have a significant impact on HCT compared to the longer-acting forms of TTh.

Efficacy and safety outcomes of a compounded testosterone pellet versus a branded testosterone pellet in men with testosterone deficiency: a single-center, open-label, randomized trial

Background

Testosterone deficiency (TD) is a prevalent condition, especially in men ≥45 years old, and testosterone therapy (TTh) can improve the quality of life in these patients.

Aim

To evaluate the safety profile of compounded subcutaneous testosterone pellets and to compare the efficacy between compounded and market brand testosterone pellets for TTh: E100 (Empower Pharmacy) and Testopel (Food and Drug Administration approved), respectively.

Methods

This was a prospective, phase 3, randomized, noninferiority clinical trial. We enrolled 75 men diagnosed with TD and randomized them 1:1 to a market brand group and a compounded pellet group. The patients were implanted with their respective testosterone pellets: Testopel (10 pellets of 75 mg) and E100 (8 pellets of 100 mg).

Outcomes

We evaluated adverse events after implantation and followed men at 2, 4, and 6 months for morning laboratory levels (prior to 10 am): serum testosterone, estradiol, hematocrit, and prostate-specific antigen.

Results

After randomization, 33 participants were enrolled in the Testopel arm and 42 in the E100 arm. Serum testosterone levels were similar between the groups at 2, 4, and 6 months, with most men (82%) dropping to <300 ng/dL by the end of the trial. Adverse events were also similar, such as elevations in prostate-specific antigen, estradiol, and hematocrit. Most dropouts were related to persistent TD symptoms and serum testosterone <300 ng/dL, with similar rates between the groups in the study.

Clinical Implications

Men treated with Testopel and E100 pellets had comparable serum testosterone levels and similar adverse event rates, providing an effective choice of long-term TTh among men with TD.

Strengths and Limitations

Strengths include the prospective, randomized, single-blinded study design and adequate follow-up. Limitations include the lack of external validity and the single-institution cohort.

Conclusion

E100 compounded testosterone pellets are a noninferior option of TTh as compared with Testopel for men presenting with TD.

Management of large kidney stones in the geriatric population

PURPOSE

The aim of this review is to highlight the unique factors that predispose geriatric patients to nephrolithiasis and to compare the utility and efficacy of surgical techniques in this specific patient population.

METHODS

PubMed and EMBASE databases were reviewed, and studies were organized according to surgical treatments.

RESULTS

Few prospective studies exist comparing kidney stone removal in the elderly to younger cohorts. In addition, various age cut-offs were used to determine who was considered elderly. Most studies which analyzed Percutaneous Nephrolithotomy (PCNL) found a slightly higher rate of minor complications but comparable stone free rate and operative time. For ureteroscopy (URS) and extracorporeal shockwave lithotripsy (ESWL), there were minimal complications observed and no difference in clinical success in the elderly. All surgical techniques were presumed to be safe in the elderly and most found no difference in stone-free rates.

CONCLUSIONS

Unique attributes of the geriatric population contribute to stone formation and must be considered when determining appropriate management modalities. This review provides an overview of the utility and efficacy of PCNL, URS and ESWL in the elderly, as well as a porposed algorithm for management in this population.

TikTok as a source of information regarding premature ejaculation: a qualitative assessment

Background

Patients are increasingly looking to social media platforms for medical information.

Aim

In this study we aimed to evaluate the quality of information regarding premature ejaculation (PE) on TikTok.

Methods

The term "premature ejaculation" was searched on TikTok on a single day in May 2022. Videos were sorted by 3 reviewers as reliable or unreliable based on the accuracy of video content. Relevant user metrics were collected for each video, including the numbers of likes, shares, and followers, and the video length, source of upload, and speaker type. The quality of information was objectified with 2 validated tools, with mean scores obtained from the 3 reviewers, the Patient Education Materials Assessment Tool (PEMAT) and the 5-point modified DISCERN instrument.

Outcomes

Outcomes were video reliability categorization, video and user metrics as described above, and video quality as quantified by PEMAT and DISCERN scores.

Results

Eight videos were categorized as reliable and 32 videos were categorized as unreliable. The mean number of "likes" per video was higher in the reliable than in the unreliable group (1238 vs 126, P < .018). Accounts posting reliable videos had higher mean numbers of followers than those posting unreliable videos (55 050 vs 12 042, P = .025). The majority of unreliable videos (75%) vs reliable videos (12.5%) were posted by self-identified patients or individual users, whereas 62.5% of reliable videos vs versus 6.3% of unreliable videos were posted by individual physicians or physician groups. Few videos overall mentioned PE definition, indications for PE treatment, types of treatment, or value of psychological intervention (12.5%, 15%, 22.5%, and 5.0% of videos, respectively). Video length and number of shares did not differ between groups. Reliable videos had higher PEMAT (73.0 vs 45.1, P < .001) and DISCERN (2.7 vs 0, P < .001.) scores.

Clinical implications

There exists a critical need for enhanced quality of medical information on social media platforms in hopes of encouraging patients with impaired sexual function to seek appropriate medical care.

Strength and limitations

Strengths of this study include the objective use of validated quality assessment tools and a focus on TikTok as an emerging social media platform. Limitations include large numbers of excluded videos.

Conclusion

The quality of available information regarding PE on TikTok is low, with a significant percentage of videos on this topic fraught with inaccuracies. Given TikTok's prominence as a social media platform primarily geared toward younger audiences, we emphasize the need for improvement in the quality of information available regarding PE and its management.

Evaluating the American Urologic Association (AUA) dietary recommendations for kidney stone management using the National Health And Nutritional Examination Survey (NHANES)

The objective of this study is to evaluate the conventional dietary recommendations for stone prevention among patients in the National Health and Nutritional Examination Survey (NHANES) and compare dietary components and special diets between stone formers and non-stone formers. We analyzed the NHANES 2011-2018 dietary and kidney condition questionnaires, among 16,939 respondents who were included in this analysis. Dietary variables were selected based on the American Urological Association (AUA) guideline for Medical Management of Kidney Stones and from other studies on kidney stone prevention. Weighted multivariate logistic regression models were used to assess the relationship of dietary food components (categorized into quartiles) and dietary recommendations with kidney stone formation (yes vs no), adjusted for total caloric intake, comorbidities, age, race/ethnicity, and sex. The prevalence of kidney stones was 9.9%. Our results showed association of kidney stones with lower levels of potassium (p for trend = 0.047), which was strongest for < 2000 mg (OR = 1.35; 95% CI 1.01-1.79). Higher vitamin C intake was inversely associated with stone formation (p for trend = 0.012), particularly at daily intake levels between 60 and 110 mg (OR = 0.76; 95% CI 0.60-0.95) and above 110mcg (OR = 0.80; 95% CI 0.66-0.97). There were no associations between other dietary components and kidney stone formation. Higher levels of dietary vitamin C and potassium intake may be indicated for stone prevention and warrants further investigation.

Rezum Outcomes in Relationship to Number of Injections: Is Less More?

Objectives: To assess efficacy and safety outcomes in relationship to the number of injections given during Rezum treatment. Methods: A retrospective study was conducted on patients with moderate to severe lower urinary tract symptoms (LUTS) treated with Rezum. Patients were stratified into cohorts based on the number of injections received per lateral prostatic lobe: 1, 2, 3, or 4 injections. International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), International Index of Erectile Function (IIEF)-Erectile Function, IIEF-Orgasmic Function, and adverse events were collected at baseline, 1, 3, 6, and/or 12 months postoperatively. Results: A total of 179 patients were included: 58, 91, 22, and 8 patients in the 1, 2, 3, and 4 injections cohorts, respectively. Baseline demographics significantly different across cohorts were age, history of urinary retention, prostate-specific antigen, prostate volume, prostatic urethral length, and presence of median lobe. At 3 months, all cohorts reported significant improvements in IPSS and QoL, which remained durable to 12 months. There were no significant differences in changes in IPSS, QoL, PVR, and IIEF-Erectile and Orgasmic Function between the cohorts at any follow-up. Multiple linear regression showed that the number of injections did not predict changes in IPSS, QoL, PVR, and IIEF-Erectile and Orgasmic Function at any follow-up (p > 0.05) but predicted change in Qmax at 3 months (β = 5.7, p = 0.019). Multiple logistic regression showed that for each additional injection, the odds of gross hematuria, penile burning, penile pain, and dysuria increased by 3.8, 2.6, 2.2, and 3.0, respectively. Conclusions: Utilizing less injections represents a safe treatment strategy without compromising Rezum's efficacy in providing durable relief in LUTS.

Risk Factors and Real-World Short-Term Outcomes of a Failed Trial of Void After Rezum Therapy in a Multiethnic Population

Background: Postoperative urinary retention is a common complication following surgery for benign prostatic hyperplasia. We aimed to identify risk factors for a failed trial of void (TOV) following treatment with the Rezum system and assess the impact of a failed TOV on short-term outcomes. Methods: A single-office retrospective study was conducted on patients treated with Rezum therapy between 2017 and 2019. A urinary catheter was placed in all patients following Rezum therapy. Demographic data and outcome measures, including the International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), and adverse events, were analyzed at baseline and 1, 3, and/or 6 months postoperatively. Risk factors were identified through multivariate logistic regression analysis. Results: A total of 289 patients were included. Thirty-five patients (12.1%) failed a TOV, while 254 (87.9%) had an effective TOV. All patients were given a TOV after a median of 5 days (4-5). Those who failed the TOV spent an additional mean of 13.7 ± 13.3 days with a catheter. Patients who failed the TOV were more likely to get a urinary tract infection compared with those who had an effective TOV (20.0% vs 4.7%, p < 0.001). All patients experienced significant improvements in IPSS, QoL, and Qmax at 1, 3, and/or 6 months. On multivariate analysis, a high baseline PVR was the only independent predictor of a failed TOV (odds ratio: 1.01, 95% confidence interval 1.00-1.01). A greater proportion of patients with a baseline PVR >200 mL failed the TOV (40.0%) compared with patients with a baseline PVR <200 mL (10.9%, p = 0.008). Conclusions: Approximately one in eight patients failed the TOV following Rezum therapy. Baseline PVR was the only independent risk factor for a failed TOV. Nevertheless, all patients experienced significant relief of urinary symptoms. Patients with high baseline PVR, particularly >200 mL, may require a catheter for an extended duration.

Comparing Rates of Polycythemia in Hypogonadal Men Using Nasal Testosterone Gel Versus Intramuscular Testosterone: Update of a Randomized Clinical Trial

Men with hypogonadism who use intranasal testosterone are less likely to develop polycythemia than men using intramuscular testosterone cypionate.

Pilot Study: Next-generation Sequencing of the Semen Microbiome in Vasectomized Versus Nonvasectomized Men

BACKGROUND

Approximately half a million vasectomies are performed every year in the USA. There is a paucity of literature on the impact of male sterilization on the semen microbiome and whether it prompts microbiota dysbiosis.

OBJECTIVE

To investigate if vasectomy induces changes in the seminal microbiome via comparison of semen samples from men before and after vasectomy, and if the seminal microbiome profiles for vasectomized men follow a particular pattern with respect to diversity and abundance.

DESIGN, SETTING, AND PARTICIPANTS

From July 2021 to February 2022, we prospectively collected and analyzed semen samples from 58 men at one outpatient clinic. Eighteen men provided a semen sample before and 3 mo after vasectomy. We also collected semen samples from 22 fertile nonvasectomized men and from a further 18 vasectomized men at 3 mo after vasectomy.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Semen microbiome α-diversity, beta-diversity, and relative abundance were compared initially between paired and then between unpaired vasectomized and nonvasectomized samples. Analysis of variance (ANOVA), permutational multivariate ANOVA, and analysis of the composition of microbiomes with bias correction were used to assess differences.

RESULTS AND LIMITATIONS

In both paired and unpaired sets of samples, a decreasing trend for α-diversity in semen after vasectomy was observed. Shannon diversity, the relative abundance of species with an abundance >2%, and composition were not significantly changed. Sphingomonas, Brevundimonas, and Paracoccus abundance decreased after vasectomy, while Corynebacterium abundance increased. The results may be limited by the sample size and lack of demographic heterogeneity.

CONCLUSIONS

Vasectomy is followed by a decrease in α-diversity and changes in the relative abundance of bacterial species in the semen microbiome. Further investigation is necessary to understand the clinical significance of these changes after vasectomy.

PATIENT SUMMARY

We evaluated changes in the bacteria species in semen after vasectomy. We found that vasectomy decreased the richness and evenness of bacteria species in semen, but the overall bacterial community remained similar. Further studies are needed to assess the implications of changes in semen bacteria after vasectomy.

Testosterone Therapy in Men with Klinefelter Syndrome: Analysis of a Global Federated Research Network

INTRODUCTION

The objective of this study was to determine the rates of hypogonadism and prescription of testosterone replacement therapy (TRT) in men with Klinefelter syndrome (KS). We hypothesized that men with KS are under-treated for testosterone deficiency with TRT due to a combination of factors, including a poor understanding of hypogonadism in this population and neurocognitive issues leading to delay in seeking of treatment for hypogonadism.

MATERIALS & METHODS

We queried TriNetX, a large multicenter electronic health record database, to identify all men with a diagnosis of KS (ICD-10-CM Q98.4). Prevalence of testosterone deficiency was determined as defined by testosterone level < 300 ng/dL. The primary outcome of the study was prescription of any of the following forms of TRT on the day of diagnosis or later.

RESULTS

There were in total 5437 men with diagnosis of KS. A total of 1581 men with KS received laboratory measurement of testosterone level, 1113 (70.4%) of whom were hypogonadal. Mean testosterone level in this group was 354 ng/dL [50-658]. Of the 1113 men found to be hypogonadal, only 657 (59.0%) men were given prescription for TRT.

DISCUSSION & CONCLUSION

This is the first study to evaluate TRT prescribing habits in men with KS. In this large retrospective study, TRT was underprescribed in men with KS. Further studies are needed to corroborate these findings and to evaluate barriers to receiving care in this population.

The Impact of Holistic Review of Urology Residency Applications on Selection for Interview During the COVID-19 Pandemic

OBJECTIVE

To investigate the impact of a holistic review of urology residency applications on interview selection at our institution during the COVID-19 pandemic.

METHODS

In the 2019-2020 cycle, applicants were filtered by a Step 1 score of 230 and whether they applied from selected east coast medical schools. For the 2020-2021 and 2021-2022 cycles, we implemented a scoring system which focused on desirable attributes based on our program training needs and resources. We compared applicant and interviewee demographics and United States Medical Licensing Examination (USMLE) scores using descriptive statistics and 1-way analysis of variance tests.

RESULTS

A total of 282, 300, and 367 students applied to our residency program with 50, 45, and 52 selected for interviews during the 2019-2020, 2020-2021, and 2021-2022 cycles, respectively. Compared to 2019-2020, the 2020-2021 and 2021-2022 interviewee cohorts comprised of more non-tri-state applicants (36%, 55.6%, and 46.2%, respectively). Underrepresented minority representation increased for the 2020-2021 interviewee cohort; however, this was not observed in 2021-2022 (16%, 24.4%, 15.4%, respectively). Additionally, USMLE Step 1 and 2 scores were similar between interviewee cohorts in 2019-2020, 2020-2021 and 2021-2022, respectively (Step 1: 244.2 ± 8.8, 242 ± 12.1, 242.8 ± 12.4, P = .624) (Step 2: 249.1 ± 11.5, 251.5 ± 10.5, 254.4 ± 10.8, P = .143).

CONCLUSION

Utilizing a comprehensive review resulted in a geographically diverse interview pool and no significant difference in academic performance among interviewees. Holistic review provides an alternative, balanced evaluation of residency applicants which may increase diversity in urology.

Persistent Testosterone Suppression After Cessation of Androgen Deprivation Therapy for Prostate Cancer

Introduction Many men receiving temporary androgen deprivation therapy (ADT) for localized prostate cancer fail to achieve baseline testosterone levels after cessation. Testosterone recovery in men with localized prostate cancer receiving temporary ADT was assessed. Methods A global federated health research network (TriNetX) was used to identify men diagnosed with prostate cancer undergoing temporary ADT. Two cohorts were identified: men receiving luteinizing hormone-releasing hormone (LHRH) antagonists or LHRH agonists, and men receiving combined ADT (LHRH agonist and antiandrogens). Further stratification was based on a treatment duration of six months (short-term) or 18 months (long-term) to compare testosterone (T) recovery profiles five years after ADT cessation. Results A total of 28,583 men received LHRH agonist or antagonist therapy alone, and 20,188 men received combination ADT. A total of 46.7% of men who received short-term LHRH agonists or antagonists and 40.6% of men who received short-term combined ADT, recovered to mean baseline T levels at five years. Only men who received short-term LHRH agonists/antagonists recovered to eugonadal levels at the five-year follow-up. Around 50% of men who received long-term LHRH agonist/antagonist therapy and 10.7% of men who received combined ADT, recovered to mean baseline T levels at five years. However, neither group recovered to eugonadal T levels. Conclusions At the five-year follow-up after ADT cessation, most patients failed to recover to their mean baseline and eugonadal T levels. Given that testosterone deficiency is associated with metabolically adverse changes in body composition, increased insulin resistance, impaired bone health, and hypogonadal symptoms, serum T levels must be closely monitored in men receiving ADT following treatment cessation.

Clinical Risk Factors Associated With Small Renal Mass Malignant Histology in a Multi-Ethnic Population Undergoing Partial Nephrectomy

INTRODUCTION

Small renal masses (SRMs) are often incidentally diagnosed, and a large proportion are malignant. However, there is a paucity of data describing predictors of malignancy in minority patients with SRMs. Thus, our goal was to examine clinical risk factors associated with SRM malignant histology in patients undergoing partial nephrectomy (PN) a diverse, urban academic center.

MATERIALS AND METHODS

Patients with a SRM undergoing PN at a single institution between 2010 to 2018 were reviewed. Demographic, clinical, and imaging characteristics were compared to pathology results. Logistic regression was used to examine associations between demographic/clinical variables for malignant and high-grade histology.

RESULTS

In total, 331 patients who underwent PN for SRM were included. Of those, 264 (79.8%) had malignant histology while 67 (20.2%) had benign histology. The proportions of men and of current smokers were significantly higher among patients with malignant histology. In multivariate models, non-Hispanic Black (NHB) patients had increased odds of having malignant histology (OR 2.46, 95% CI: 1.01-5.99, P = .048) and current smokers (OR = 4.02; 95% CI 1.14-14.18, P = .031). Hispanic patients had a 3-fold increased risk of high-grade RCC (OR 3.06, 95% CI: 1.19-7.87, P = 0.02) compared to Non-Hispanic White patients.

CONCLUSION

In our population, male sex, smoking, and NHB race/ethnicity was associated with an increased risk of malignancy in patients undergoing partial nephrectomy for SRM. Older age and Hispanic race/ethnicity were associated with high grade RCC. Our results suggest that urologists should exercise a higher level of vigilance in managing and treating SRM among NHB and Hispanic patients.

Assessing the quality and readability of online content on shock wave therapy for erectile dysfunction

Patients are becoming increasingly reliant on online platforms for obtaining health information. Previous research has shown that the quality of information available on the internet regarding novel medical therapies is generally poor and frequently misleading. Shock wave therapy represents a novel restorative therapy for erectile dysfunction (ED) that has recently gained attention. We hypothesised that online sources regarding shock wave therapy for ED would be fraught with misleading claims and unreliable health information. Our objective was to evaluate the quality and readability of online medical information on shock wave therapy as a treatment for ED. Websites were generated using a Google search of 'shock wave therapy for erectile dysfunction' with location filters disabled. Readability was analysed using the Readable software (Readable.com, Horsham, United Kingdom). Quality was assessed independently by three reviewers using the DISCERN tool. Articles were subdivided into those from private clinic websites and those from universities or news media websites. Statistical analysis was conducted using the Student's t test. Nine articles that resulted from the Google search had mean readability scores as follows: Flesch-Kincaid grade level (10.8), Gunning-Fog Index (13.67), Coleman-Liau Index (12.74), Simple Measure of Gobbledygook (SMOG) Index (13.33), FORCAST Grade Level (11.33), and Automated Readability Index (11.08). The mean Flesch Reading Ease score was 46.4. The articles had a mean DISCERN score of 3.1, suggesting 'moderate quality' content. Articles from universities (n = 2) or news sources (n = 3) had significantly higher DISCERN scores than articles from private medical practices (n = 4). There was no difference in readability scores between the groups. Articles from private clinics are just as readable as those from universities or news media, but they are significantly more biased and misleading. The current online material relating to shock wave therapy for ED may not adequately inform patients in their medical decisions making, thereby necessitating closer collaboration between the sources disseminating information and urologists.

Case - Testicular thigh pouches for severe Fournier's gangrene: A how-to guide

Fournier’s gangrene is a surgical emergency that requires prompt debridement of infected tissue. When the majority of scrotum has been resected, placing the testicles into thigh pouches can allow for improved wound granulation/contracture prior to definitive tissue reconstruction. We present a surgical guide on how to create testicular thigh pouches without the use of thigh counter-incisions, and its utility in delayed wound healing for large scrotal wounds. This technique may serve as a valuable adjunct in the urologist’s and plastic surgeon’s armamentarium to optimize testicular coverage and subsequent genital reconstruction.

Professional Burnout of Advanced Practice Providers Based on 2019 American Urological Association Census Data

INTRODUCTION

Burnout has been recognized as an occupational hazard among health care professionals. The objective of this study was to assess the extent and pattern of burnout in advanced practice providers (APPs) in urology by analyzing American Urological Association Census data.

METHODS

The American Urological Association conducts an annual census survey to all providers in the urological care community, including APPs. In the 2019 Census, the Maslach Burnout Inventory questionnaire was included to measure burnout among APPs. Demographic and practice variables were assessed to establish correlating factors to burnout.

RESULTS

A total of 199 APPs (83 physician assistants and 116 nurse practitioners) completed the 2019 Census. Slightly more than 1 in 4 APPs experienced professional burnout (25.3% in physician assistants and 26.7% in nurse practitioners). Observed higher burnout rates were seen in APPs who were aged 45 to 54 (34.3%), women (29.6% vs 10.8% in men, p value <0.05), non-White (33.3% vs 24.9% in White), those who had 4-9 years of practice (32.4%) and those who practiced in academic medical centers (31.7%). Except for gender, none of the above observed differences were statistically significant. Using a multivariate logistic regression model, gender remained the only significant factor associated with burnout (women vs men with an odds ratio of 3.2 [95% confidence interval: 1.1-9.6]).

CONCLUSIONS

Overall, APPs in urological care reported lower levels of burnout than urologists; however, there was a higher chance of female APPs experiencing higher professional burnout in comparison to their male counterparts. Future studies are needed to investigate possible reasons for this finding.

Comparison of Patient Satisfaction and Safety Outcomes for Postoperative Telemedicine vs Face-to-Face Visits in Urology: Results of the Randomized Evaluation and Metrics Observing Telemedicine Efficacy (REMOTE) Trial

INTRODUCTION

There is a need to better understand the role of postoperative care via telemedicine (TM). We evaluated patient satisfaction and outcomes of postoperative face-to-face (F2F) versus TM visits for adult ambulatory urological surgeries in an urban academic center. Methods:This was a prospective, randomized controlled trial. At surgery, patients undergoing ambulatory endoscopic procedures or open surgery were randomized 1:1 to a postoperative F2F or TM visit. After the visit, a telephone survey assessing satisfaction was administered. Primary outcome was patient satisfaction; secondary outcomes were time and cost savings, and 30-day safety outcomes. Results:A total of 197 patients were approached; 165 (83%) consented and were randomized-76 (45%) to F2F and 89 (54%) to TM cohorts. There were no significant differences in baseline demographics between the cohorts. Both cohorts were equally satisfied with their postoperative visit (F2F 98.6% vs TM 94.1%, p=0.28) and found their visit to be an acceptable form of health care (F2F 100% vs TM 92.7%, p=0.06). The TM cohort saved a significant amount of time (TM 66.2% spent <15 minutes vs F2F 43.1% spent 1-2 hours, p <0.0001) and money (44.1% TM saved $5-$25 vs 43.1% F2F spent $5-$25, p=0.041) associated with travel. There were no significant differences in 30-day safety outcomes between the cohorts. Conclusions:TM for postoperative visits after ambulatory adult urological surgery saves patients time and money without compromising satisfaction or safety. TM should be offered as an alternative to F2F for routine postoperative care for certain ambulatory urological surgeries.

Idiopathic bilateral ureteral stenosis presenting as bilateral hydronephrosis

Ureteral stenosis is typically seen in the setting of genitourinary tract manipulation or nephrolithiasis. Bilateral idiopathic ureteral stenosis is an exceedingly rare clinical entity that has been described in only a small number of cases. More specifically, we describe a case of idiopathic bilateral, distal ureteral stenosis resulting in hydronephrosis and deterioration of renal function in an adolescent patient. The patient was successfully treated with robotic bilateral ureteral implants. This case brings to light a rare, but clinically relevant, cause of hydronephrosis, highlights the importance of early intervention in minimizing renal dysfunction, and describes a novel treatment option.

Gender Bias in YouTube Videos Describing Common Urology Conditions

OBJECTIVE

To study implicit and explicit gender biases in YouTube videos describing common urologic conditions based on language patterns, speaker gender, and speaker profession.

METHODS

Using a Boolean search, the top 30 videos for benign prostatic hyperplasia (BPH), kidney stones, urinary tract infections (UTIs), overactive bladder (OAB), erectile dysfunction (ED), and pelvic organ prolapse (POP) were retrieved. Using the Linguistic Inquiry and Word Count program (LIWC) software, video transcripts were analyzed for 16 word categories and compared by speaker gender and urology topic to assess for bias.

RESULTS

OAB and POP had the least view counts and subscribers; kidney stone and ED videos had the most. Student education channels were more likely to feature male than female speakers (19 male vs. 6 female, P=0.01). A significant difference was noted between speaker gender in BPH (25 male vs. 4 female, P<0.001), OAB (4 male vs. 22 female, P<0.001), and POP (6 male vs. 23 female, P<0.001) videos. When examining linguistic patterns with the LIWC program, female speakers were more likely to mention personal concerns and use tentative words when speaking alone compared to males.

CONCLUSIONS

Gender bias exists in YouTube videos concerning common urologic conditions. We must be mindful of how information is distributed in order to minimize the perpetuation of gender stereotypes that are common in medicine. Awareness of these patterns and biases should encourage Urologists to proactively consider how they present themselves and how they reference the conditions they present in social media outlets.

Clinical challenges of scrotal lymphangioma in an adult: a rare case of scrotal swelling

Scrotal lymphangiomas represent an extremely rare cause of scrotal swelling. We report a case of scrotal lymphangioma in an 18-year-old male who presented with painful scrotal swelling. Scrotal ultrasound revealed a complex multicystic structure in the left hemiscrotum. The patient underwent successful surgical excision of the mass. Postoperatively, he developed a hydrocele which eventually spontaneously regressed. Histopathology confirmed the diagnosis. We outline the unusual presentation, characteristic imaging and histology findings, and surgical management of scrotal lymphangiomas. With this information, urologists may exercise a heightened level of awareness for this rare cause of scrotal swelling.

Nanotechnology as a tool to advance research and treatment of non-oncologic urogenital diseases

Nanotechnology represents an expanding area of research and innovation in almost every field of science, including Medicine, where nanomaterial-based products have been developed for diagnostic and therapeutic applications. Because of their small, nanoscale size, these materials exhibit unique physical and chemical properties that differ from those of each component when considered in bulk. In Nanomedicine, there is an increasing interest in harnessing these unique properties to engineer nanocarriers for the delivery of therapeutic agents. Nano-based drug delivery platforms have many advantages over conventional drug administration routes as this technology allows for local and transdermal applications of therapeutics that can bypass the first-pass metabolism, improves drug efficacy through encapsulation of hydrophobic drugs, and allows for a sustained and controlled release of encapsulated agents. In Urology, nano-based drug delivery platforms have been extensively investigated and implemented for cancer treatment. However, there is also great potential for use of nanotechnology to treat non-oncologic urogenital diseases. We provide an update on research that is paving the way for clinical translation of nanotechnology in the areas of erectile dysfunction (ED), overactive bladder (OAB), interstitial cystitis/bladder pain syndrome (IC/BPS), and catheter-associated urinary tract infections (CAUTIs). Overall, preclinical and clinical studies have proven the utility of nanomaterials both as vehicles for transdermal and intravesical delivery of therapeutic agents and for urinary catheter formulation with antimicrobial agents to treat non-oncologic urogenital diseases. Although clinical translation will be dependent on overcoming regulatory challenges, it is inevitable before there is universal adoption of this technology to treat non-oncologic urogenital diseases.

Future of Male Infertility Evaluation and Treatment: Brief Review of Emerging Technology

Over the past few decades, there have been significant advances in male infertility, particularly in the development of novel diagnostic tools. Unfortunately, there remains a substantial number of patients that remain infertile despite these improvements. In this review, we take heed of the emerging technologies that will shape the future of male infertility diagnosis, evaluation and treatment. Improvement in computer-assisted semen analyses and portability allow males to obtain basic semen parameters from the comfort of their home. Additionally, breakthrough ultrasound technology allows for preoperative prediction of potential areas of spermatogenesis within the testes, high-resolution optics permits better visualization during microdissection testicular sperm extraction (mTESE), and artificial intelligence improves sperm selection and identification.

Rates of False-Negative Screening in Prostate Specific Antigen Secondary to 5-Alpha Reductase Inhibitor Usage: A Quality-Improvement Initiative

PURPOSE

Patients often take 5-alpha reductase inhibitors (5-ARIs) for the management of benign prostatic hyperplasia. However, 5-ARIs can decrease prostate specific antigen (PSA) by approximately half and therefore may lead to false negative PSA tests. We investigated false-screening rates in men on 5-ARIs undergoing PSA testing and whether ordering physicians noticed false negative findings.

MATERIALS AND METHODS

A single institution, retrospective study was conducted on patients with a PSA value documented between 2014 and 2017. Patient demographics, PSA results, 5-ARI usage, and providing clinician characteristics were collected. Published normal PSA values were used to determine PSA test positivity; values for those on 5-ARIs were doubled.

RESULTS

A total of 29,131 men were included. 1,654 (5.7%) were prescribed 5-ARIs at least 12 months prior to PSA evaluation. 118 men (7.1%) had a value that would be positive if corrected for 5-ARI usage, 33 (27.9%) of which had no indication that the provider had noted this. There was no effect on rates of false negative values if the PSA was ordered by a different provider than the one who prescribed the 5-ARI (p = 0.837). However, if the provider who ordered the PSA test was an urologist, the likelihood that a false negative value would be identified was lower (p=0.001).

CONCLUSIONS

More than a quarter of men with false negative tests were missed. This occurred more often when the ordering provider was not an urologist. An educational opportunity exists to improve the quality of PSA testing by preventing false negative tests.

The Effect of Sperm DNA Fragmentation on Male Fertility and Strategies for Improvement: A Narrative Review

The inability to conceive due to male infertility is a complex issue with a wide variety of etiologies. Sperm DNA damage can be both a barrier to natural pregnancy and successful assisted reproductive technology (ART). The aim of this narrative review was to describe and highlight the effects of sperm DNA fragmentation and the most recent data on various treatment strategies to decrease sperm DNA damage. Finally, we proposed a management algorithm for couples undergoing ART with increased sperm DNA fragmentation.

Emerging outcomes of water vapor thermal therapy (Rezum) in a broad range of patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia: A systematic review

Water vapor thermal therapy (Rezum) is a novel, minimally invasive surgical technology used to treat lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). The objective of this systematic review is to evaluate the latest efficacy and safety profile of Rezum in patients with LUTS secondary to BPH. PubMed/MEDLINE and the Cochrane Library databases were systematically searched, in accordance with the PRISMA statement, for relevant articles in the English language till 1 August 2021. Randomized and nonrandomized studies that evaluated urinary outcomes and/or adverse events were deemed eligible. Nineteen studies (N = 1942), published in 25 articles, were included. International Prostate Symptom Score (IPSS), quality of life (QoL), and maximum urinary flow rate (Qmax) significantly improved as early as 1 month postoperatively and remained durable for up to 5 years. Significant median percent improvements in IPSS, QoL, and Qmax at 3 months were 51%, 51%, and 66%, respectively. Patients with obstructive median lobes, large prostates (>80 g), small prostates (<30 g), and urinary retention also experienced significant relief in LUTS, with 83% of urinary retention patients becoming catheter independent at a median of 14 days.
