Objective: Digital flexible ureteroscopes (DFUs) play a crucial role in endourological procedures, and scope breakages are often avoidable with proper measures in place. We aimed to evaluate the effect of mandatory training on DFU durability and to assess the influence of various factors on instrument damage. Materials and Methods: Mandatory training involving instructional videos on DFU care was introduced for all processing and operating room staff handling DFUs. Only certified personnel were allowed to handle DFUs, with meticulous usage documentation. The average annual usage of each DFU was compared pre and post program implementation. We examined factors such as patient demographics, procedure details, and operator experience impacting scope life using negative binomial regression. Results: The average usage of DFU increased by 21%, from 6.38 to 7.74 cases. We found that post-graduate year stood out as a significant predictive factor (estimate = 3.28, p = 0.04). Moreover, the streamlined model revealed that previous ureteral-stent use (estimate = 0.94, p < 0.001), struvite stones (estimate = 3.08, p = 0.01), and a higher number of stones (estimate = 0.11, p = 0.04) were associated with an increased number of procedures before DFU breakage, whreas in situ lithotripsy in the lower calyx was associated with a reduced number of procedures before DFU breakage (estimate = -1.11, p = 0.003). Conclusion: Implementing a mandatory training program showed an increase in DFU durability by 21%, suggesting a potential reduction in annual repair and replacement costs by the same percentage. Furthermore, outcomes were more favorable when experienced practitioners conducted treatments, especially in cases involving struvite stones.

Purpose: The goal of this systematic review is to assess the temporal changes in outcomes and complications of transurethral resection of the prostate (TURP) from 2000 to 2022., Methods: We conducted a systematic review and meta-analysis of 103 randomized clinical trials from PubMed on TURP, involving 8521 patients. Studies were grouped by years: 2000-2004, 2005-2009, 2010-2014, and 2015-2022. We assessed International Prostate Symptom Score (IPSS), Peak Flow (Qmax), Post-void residue of urine (PVR), and post-operative complications. Heterogeneity was ranked as low (I 2  < 25%), moderate (I 2  = 25-75%), or high (I 2  > 75%)., Results: TURP significantly improved IPSS, Qmax, and PVR, with the most recent studies showing superior results in IPSS and Qmax after 3 years compared to 2000-2004 studies. Heterogeneity in PVR was high (I 2  = 100%). No negative impact on erectile function was observed. Complication rates included TURP syndrome (2%), bleeding (8%), and blood transfusion (6%), but elevated heterogeneity with difference between the groups was seen in clot evacuation (I 2  = 83%) and urinary tract infections (I 2  = 82%). Other complications were urinary retention (4%), incontinence (8%), urethral stricture (3%), bladder neck stenosis (2%)., Conclusion: In the last 20 years there has not been a clear trend in the results of TURP. The found heterogeneity may indicate a lack of standardization in TURP procedures. However, symptomatic improvement among patients is uniform, which supports this procedure as a historical benchmark surgical treatment for BPH., Competing Interests: Declarations Conflict of interests The authors declare no competing interests.

Inflatable penile prosthesis (IPP) implantation is a surgical approach for the management of erectile dysfunction (ED). A feared complication is IPP infection, and increased operative time is a risk factor for infection. Exposure of an IPP implant to ambient air in the operating room (OR aerobiome) is thought to contribute to risk of infection from increased operative time, but this is not well-supported. The objective of this study was to evaluate if exposure to the OR aerobiome increased microbial colonization of IPPs. This was an ex vivo study using an uncoated IPP, observing standard surgical sterility and OR conditions. A sterile swab was collected every 30 min for 3 h from each IPP component. Positive controls consisted of swabs exposed to unprepped scrotal skin during in-office vasectomies. All swabs underwent quantitative polymerase chain reaction (qPCR) and next generation sequencing (NGS). Bioinformatic processing was carried out and taxonomic assignment was performed. No microbial growth was detected on any component of the IPPs at any time point, while positive control swabs all detected various skin flora, including bacterial and fungal growth. These findings suggest that exposure to the OR aerobiome does not increase the risk of IPP microbial colonization, at least within a 3-hour period. Further in vivo studies are needed., (© 2024.

Introduction: The role of voiding cystourethrogram (VCUG) in evaluating vesicoureteral reflux (VUR) in patients with known ureteropelvic junction obstruction (UPJO) remains unclear. While VCUG is frequently performed, the incidence of concomitant VUR and UPJO is low, and VUR is often low-grade with high rates of spontaneous regression., Objective: To analyze the clinical relevance of VCUG in patients with UPJO by determining its incidence and studying the difference in clinical outcomes between patients with known, unknown, and negative VUR., Study Design: Retrospective review of patients with UPJO who underwent pyeloplasty from 2012 to 2020 with <18 years-old, unilateral UPJO, postoperative follow-up of ≥2 months and had at least 1 renal ultrasound (US) after pyeloplasty. Results were compared among 3 groups: patients who underwent VCUG before pyeloplasty and were found to have VUR (group 1), patients who underwent VCUG before pyeloplasty without VUR (group 2), and patients who did not have a VCUG before pyeloplasty (group 3)., Results: A total of 275 patients met the inclusion criteria, of which 21 patients were classified in group 1, 166 patients in group 2, and 88 patients in group 3 (Table). The age at preoperative VCUG was 14.7 ± 32.9 months in group 1 and 15.17 ± 35.8 months in group 2 (p = 0.960). Overall, the incidence of concomitant UPJO and VUR was 11.2%. In group 1 the initial VUR grade was 5 in 2 patients, 4 in 3, 3 in 5, 2 in 7, and 1 in 4 patients. Of these, only 1 patient required ureteral reimplantation after pyeloplasty. Post-pyeloplasty, no significant differences were observed in complications (p = 0.7436), length of follow up (p = 0.3212), SFU grade 4 hydronephrosis (p = 0.2247), postoperative UTIs (p = 0.1047) and pyeloplasty success rate (p = 0.4206) among the 3 groups. Despite the use of antibiotic prophylaxis being significantly different amongst the three groups (p < 0.001), it was not associated with a lower incidence of postoperative UTIs (group 1 p = 0.068, group 2 p = 0.486, group 3 p = 1). In patients with reflux, an increase in age was associated with a decrease in the rates of complications (p = 0.019)., Conclusion: We found no significant difference in the outcomes in patients who had a preoperative VCUG as compared to those who did not. The preoperative diagnosis of VUR by VCUG changed the management in less than 1% of the study population and thus its role in patients with UPJO should be reevaluated., Competing Interests: Conflict of interest None., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: The study aims to determine whether body mass index (BMI), metabolic syndrome (MS) or its individual components (primary hypertension, type 2 diabetes mellitus and dyslipidemias) are risk factors for common urological diseases., Materials and Methods: Cross-sectional study with data collected on February 28, 2022 from the TriNetX Research Network. Patients were divided in cohorts according to their BMI, presence of MS (BMI > 30 kg/m 2 , type 2 diabetes mellitus, primary hypertension and disorders of lipoprotein metabolism) and its individual components and its association with common urological conditions was determined. For each analysis, odds ratio (OR) with 95% confidence intervals were calculated. Statistical significance was assessed at p  < .05., Results: BMI > 30 kg/m 2 was associated with increased risk of lithiasis, kidney cancer, overactive bladder, male hypogonadism, benign prostatic hyperplasia, and erectile dysfunction ( p  < .05). On the contrary, BMI was inversely associated with ureteral, bladder and prostate cancer ( p  < .05). In all urological diseases, MS was the strongest risk factor, with prostate cancer (OR = 2.53) showing the weakest and male hypogonadism the strongest (OR = 13.00) associations., Conclusions: MS and its individual components were significant risk factors for common urological conditions. Hence holistic approaches with lifestyle modification might prevent common urological disease.Key messagesOverall, metabolic syndrome is the strongest risk factor for all the analysed urological diseases.Abnormally high body mass index can be a risk or protective factor depending on the threshold and urological disease that are being evaluated.Metabolic syndrome and increased BMI should be considered important factors associated to the prevalence of common urological diseases.

Purpose: The goal of this systematic review was to examine the current literature on the urinary microbiome and its associations with noninfectious, nonmalignant, urologic diseases. Secondarily, we aimed to describe the most common bioinformatics used to analyze the urinary microbiome., Methods: A comprehensive literature search of Ovid MEDLINE using the keywords "microbiota" AND "prostatic hyperplasia," "microbiota" AND "urinary bladder, overactive," "microbiota" AND "pelvic pain," and "microbiota" AND "urolithiasis" OR "nephrolithiasis" OR "urinary calculi" AND "calcium oxalate" was performed to identify relevant clinical microbiome studies associated with noninfectious benign urological conditions published from 2010 to 2022. We included human studies that evaluated the urinary, stone, or semen microbiota, or any combination of the above-mentioned locations., Results: A total of 25 human studies met the inclusion criteria: 4 on benign prostatic hyperplasia (BPH), 9 on overactive bladder (OAB), 8 on calcium oxalate stones, and 4 on chronic pelvic pain syndrome (CPPS). Specific taxonomic profiles in the urine microbiome were associated with each pathology, and evaluation of alpha- and beta-diversity and relative abundance was accounted for most of the studies. Symptom prevalence and severity were also analyzed and showed associations with specific microbes., Conclusion: The study of the urogenital microbiome is rapidly expanding in urology. Noninfectious benign urogenital diseases, such as BPH, calcium oxalate stones, CPPS, and OAB were found to be associated with specific microbial taxonomies. Further research with larger study populations is necessary to solidify the knowledge of the urine microbiome in these conditions and to facilitate the creation of microbiome-based diagnostic and therapeutic approaches., (© 2023.

Introduction and Objective: The long-term outcomes of varicocelectomy in adolescents is debated. The aim of this study was to evaluate symptom improvement, hypogonadism, and paternity in those who underwent adolescent sub-inguinal microscopic varicocelectomy., Material and Methods: A retrospective chart review was done of adolescents (median=19, interquartile range (IQR)=16-19.75 years) who underwent microscopic varicocelectomy between 2011 and 2021. Demographics, surgical indications, and outcomes were collected, as well as pre- and postoperative hormone levels and semen parameters. A questionnaire was prospectively collected to evaluate orchialgia, paternity, and symptoms of hypogonadism. Descriptive statistics and t-tests were performed, with significance assessed at p-value < 0.05., Results: A total of 46 adolescents were included. Age at the time of diagnosis and surgery was 19 (IQR=16-20) and 19 (IQR= 18-21) years, respectively. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and total testosterone were not affected after surgery. Similarly, semen parameters were preserved after varicocelectomy, with median concentration increasing from 12x10 6 /ml to 16x10 6 /ml but not reaching significance (p=0.272). A total of 26 men completed the questionnaire. The age of responders was 22 (IQR=21-24) years, and the time after having had the varicocelectomy was 36.5 (IQR= 18.25-62.25) months. Orchialgia persisted in five men, and three reported having a recurrence. Two men, who had a preoperative abnormal semen analysis, were actively trying to have children and reported successfully having achieved natural pregnancies. None of the patients reported having hypogonadism, and none were receiving testosterone therapy., Conclusion: Our study suggests that microscopic varicocelectomy in adolescents appears to be a safe and feasible procedure with a low rate of syndrome recurrence and no association with symptoms or biochemical evidence of hypogonadism., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2023, Porto et al.)

Introduction Infertility affects a significant portion of couples seeking pregnancy, leading to stress and emotional strain. Ovulation calculators, widely used as a tool to predict fertile days, may play a role in the stress experienced by couples undergoing fertility treatments. The aim of this study was to evaluate the impact of ovulation calculators on the stress levels of couples seeking fertility. Methods Participants were recruited from the University of Miami Health System Clinics. Fifty couples consulting for infertility were asked to participate in the study and complete anonymous self-reported surveys. The surveys consisted of validated questions related to stress levels and the use of ovulation calculators. The completed surveys were collected and analyzed using descriptive statistics. The data collected included age, number of years trying to conceive, and answers to questions related to stress levels and the use of ovulation calculators. Responses from 50 couples who met the inclusion criteria were included in the final analysis. Results A total of 50 couples who were attempting conception and who completed all the questionnaires were included in the study. Whether or not they were using ovulation calculators, females scored similarly in the four variables of the Female Sexual Function Index (FSFI), including arousal, orgasm, satisfaction, and lubrication. When evaluating International Index of Erectile Function (IIEF) scores for male erectile function, the average score of males tracking ovulation was 12.0 ± 4.8, compared to 11.5 ± 5.4 in male patients who were not (P = 0.81). The results showed no statistically significant difference in stress levels between couples who used ovulation calculators and those who did not. However, in couples experiencing higher stress levels due to infertility, both male and female participants reported higher levels of sexual dysfunction. Fertility-related stress was also found to be significantly associated with mental health implications, with increased anxiety and depression reported by couples undergoing fertility treatments. Conclusion The findings suggest that the use of ovulation calculators did not significantly influence the stress experienced by couples seeking fertility treatment. However, the study highlights the significant impact of infertility-related stress on sexual function and mental health in both male and female partners. These results emphasize the importance of addressing the psychological aspects of infertility and providing comprehensive support to couples undergoing fertility treatments. Further research is warranted to explore the complex interplay between ovulation calculator usage, infertility-related stress, sexual dysfunction, and mental health implications in couples seeking to conceive. Healthcare providers should consider incorporating mental health support into fertility treatment programs to optimize patient outcomes and overall well-being., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Ledesma et al.)

Objectives: To study how the semen microbiome profile in men with nonobstructive azoospermia (NOA) differs from that of fertile controls (FCs)., Design: Using quantitative polymerase chain reaction and 16S ribosomal RNA, we sequenced semen samples from men with NOA (follicle-stimulating hormone >10 IU/mL, testis volume <10 mL) and FCs and performed a comprehensive taxonomic microbiome analysis., Setting: All patients were identified during evaluation at the outpatient male andrology clinic at the University of Miami., Patients: In total, 33 adult men, including 14 diagnosed with NOA and 19 with proven paternity undergoing vasectomy, were enrolled., Main Outcome Measures: Bacterial species in the semen microbiome were identified., Results: Alpha-diversity was similar between the groups, suggesting similar diversity within samples, whereas beta-diversity was different, suggesting differences in taxa between samples. In the NOA men, the phyla Proteobacteria and Firmicutes were underrepresented, and Actinobacteriota were overrepresented compared with FC men. At the genus level, Enterococcus was the most common amplicon sequence variant in both groups, whereas 5 genera differed significantly between the groups, including Escherichia and Shigella, Sneathia, and Raoutella., Conclusion: Our study showed significant differences in the seminal microbiome between men with NOA and fertile men. These results suggest a loss of functional symbiosis may be associated with NOA. Further research into the characterization and clinical utility of the semen microbiome and its causal role in male infertility is necessary., (Copyright © 2023 American Society for Reproductive Medicine.

Introduction Infertility and hypogonadism in males can greatly affect their reproductive health and overall well-being. Since exogenous testosterone administration for hypogonadism management may disrupt the normal hormonal cascade necessary for spermatogenesis, clomiphene citrate (CC) and enclomiphene citrate (EC) are medications often used to manage hypogonadism and male infertility. This study aims to directly compare the effects of CC and EC on serum testosterone levels and semen parameters in men to determine which medication may have an advantage in managing these conditions. Materials and methods We retrospectively analyzed ≥18-year-old men presenting with primary infertility, abnormal semen parameters, or hypogonadism who received CC or EC monotherapy for at least three months between January 2021 and December 2022. We compared baseline and follow-up hormone levels, semen parameters, and demographics. Variables were compared using paired and unpaired t-tests. Significance was assessed at p <0.05. Results A total of 46 men received EC and 32 men received CC. The median age was 42 (IQR: 34-47.75) years in men who received EC and 41 (IQR: 36-44) years in men who received CC ( p =0.450). The two treatment groups exhibited a significant increase in serum total testosterone, while only EC had a statistically significant increase in FSH and LH. Semen volume and concentration did not significantly change with either treatment. Sperm motility increased in both groups, but total motile sperm count (TMSC) only significantly increased in men who received EC.  Conclusions Our study found that EC and CC are effective treatments in increasing total testosterone without negatively affecting spermatogenesis. EC demonstrated to be more effective in raising gonadotropin levels and TMSC., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2023, Thomas et al.)

Introduction and Objective: The United States (US) currently faces a medical malpractice crisis, and a survey done in 2006 informed that 63% of urologists faced an average of 2.1 medical malpractice lawsuits. Surgery for benign prostatic hyperplasia (BPH) is performed by 95% of US urologists. Hence, we postulated that these procedures might be responsible for a substantial number of medical malpractice lawsuits. We examined claims related to BPH surgery in various US courts., Materials and Methods: Data were collected from Westlaw and LexisNexis databases using the keywords "benign prostatic hyperplasia," "enlarged prostate," "surgery," and "malpractice" to search for cases from the entire US from January 2000 to December 2021. We extracted details such as the type of procedure, the plaintiff and defendant, the nature of the allegation, the alleged complications, the verdict, and the compensation amount., Results: We found 30 cases in which the most common procedure was transurethral resection of the prostate (37%), with inadequate postoperative care as the most frequent reason for claims (33%). Urologists were the most frequently processed professionals (57%). The postsurgical outcomes that resulted in lawsuits were urinary incontinence (23%), erectile dysfunction (13%), and urinary retention (13%). Interestingly, 43% of the patients were inmates. Plaintiffs won only two (7%) cases: colon perforation after interstitial laser coagulation with Indigo laser and recto-urethral fistula after transurethral microwave therapy., Conclusion: Most lawsuits were related to postoperative incontinence and erectile dysfunction, with the verdict favoring the defendant in most cases. Inmates were the plaintiffs in a relatively high percentage of cases. Only two cases resulted in a plaintiff victory, wherein both cases presented unexpected and serious postsurgical complications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Porto et al.)

In adolescents with Klinefelter syndrome (KS), cryopreservation would require surgery, which might delay testosterone therapy needed for testosterone deficiency. As surgical sperm retrieval rates are similar for all age groups in the KS population, fertility preservation in KS adolescents should not be recommended., (Copyright © 2022 European Association of Urology.

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., (Copyright © 2022 European Association of Urology. Published by Elsevier B.V.

Objective: To describe the current landscape of first and last female authorship in urology journals relative to the journals' impact factor. We hypothesized that women would have a smaller proportion of publications in journals with higher impact factors., Methods: Eighteen urology journals were divided into groups based on impact factor accordingly: from 33.2 to 6.2 were classified as high (European Urology, Nature Reviews Urology, The Journal of Urology, BJU International, Prostate Cancer and Prostatic Diseases, and The Journal of Sexual Medicine), from 5.8 to 5.0 as medium (Asian Journal of Andrology, European Urology Focus, Sexual Medicine Reviews, Bladder Cancer, Prostate and World Journal of Urology), and from 4.8 to 2.2 as low (Urologic Oncology, Journal of Endourology, Neurourology and Urodynamics, Urology, Journal of Pediatric Urology and Female Pelvic Medicine & Reconstructive Surgery). A computer script was designed using Python to search PubMed and record first and last author of publications between 2015 and 2020. Gender was determined by Gender-Api (https://gender-api.com). Names with an accuracy of <90% were excluded. Type of peer-review and scope of each journal were also analyzed. Statistical analysis was performed using Matlab., Results: A total of 37,413 first and 28,414 last authors were identified during the study period. Overall, women represented 21% (8,029/37,413) of first and 15% (4,232/28,414) of last authors. Women were significantly less published in high impact journals compared to both medium and low impact journals (P <.001 in all). Among all journals, articles with female first authors were more likely to have a female last author (OR: 2.72, CI: 2.5-2.9, P <.001). Subspecialty journals had more female last authors than general journals (P <.05), and female representation increased if reviews were double-blinded (P <.001). Over the last 6 years, there has been a significant increase in female senior authorship among all journals (P = .045)., Conclusion: The proportion of female authorship was significantly lower in higher impact urology journals. While the underlying cause is likely multifactorial, this finding highlights a gender discrepancy that may impact women's ability to achieve career goals in academic medicine when compared to their male counterparts., (Copyright © 2022 Elsevier Inc.
