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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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. 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 (OSA). Those taking TTh for <16 weeks were excluded. Comparison between groups was performed with Mann-Whitney U test, Student's t-test, ANOVA, or Kruskal-Wallis test as appropriate. RESULTS: Seventy-eight matched-cohort individuals with 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 recipients (p<0.05). 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.

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.

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.
