Conservative treatment of Peyronie's disease: a guide.

PURPOSE: To review the literature on the topic, to suggest a common line of treatment applicable across a wide community of specialists, and to contribute in maintaining the high level of interest in this disease. METHODS: A comprehensive and exhaustive review of the literature was performed, identifying hundreds of articles on the topic. RESULTS: Peyronie's disease is a condition that has been recognized, studied, and treated for centuries; despite this, if one excludes surgery in cases in which the deformity is stable, no clear treatment (or line of treatment) is available for complete relief of signs and symptoms. Treatment options were divided into local, oral, and injection therapy, and a wide variety of drugs, remedies, and options were identified. CONCLUSIONS: Low-intensity extracorporeal shock wave therapy, vacuum therapy, penile traction therapy, phosphodiesterase type 5 inhibitors, hyaluronic acid, and collagenase of Clostridium histolyticum may be recommended only in specific contexts. Further studies on individual options or potential combinations are required.

Mini and Standard Percutaneous Nephrolithotomy in Obese Patients. Results from a Single-surgeon Large Series.

Background and objective: Percutaneous nephrolithotomy (PCNL) is the recommended treatment for large or complex renal stones. This study aims to evaluate the outcomes of mini PCNL in obese and nonobese patients and to compare the outcomes of mini and standard PCNL in the obese population. Methods: We retrospectively reviewed our PCNL database to identify patients who had undergone mini (Amplatz sheath size 17.5Ch) or standard (Amplatz sheath size ≥26Ch) PCNL between 2005 and 2022. First, we compared the outcomes of the two procedures in the obese (body mass index [BMI] ≥30) and nonobese (BMI<30) patients. Second, we compared the outcomes of mini and standard PCNL in the obese population. A multivariable logistic regression analysis was performed to assess the variables associated with stone-free rate (SFR) and complications. Key findings and limitations: A total of 781 patients underwent mini PCNL; there was no difference between nonobese (578) and obese (133) patients in surgical time, number of tubeless procedures, postoperative stay, SFR, and overall complication rates. Similar outcomes were also seen in the 356 patients who had undergone standard PCNL, including 276 nonobese and 80 obese patients. The comparison of mini and standard PCNL in the obese population (213 patients) showed that mini PCNL provided significant benefits in surgical time (60 vs 94 min), SFR (85% vs 63.8%), and blood transfusion rate (2% vs 10%). The multivariable analysis confirmed that mini PCNL resulted in significantly higher odds of being stone free (odds ratio [OR] 1.79) and lower odds of having a blood transfusion (OR 0.28). Conclusions and clinical implications: Obese patients can safely undergo either mini or standard PCNL; in this series, mini performed better than standard PCNL in terms of SFR and blood transfusion rates. Patient summary: In this study, we compared the outcomes of mini and standard percutaneous nephrolithotomy (PCNL) in the obese population. We found that mini PCNL had lower surgical time and blood transfusion rate, and better stone-free rate than its standard counterpart in obese patients.

Impact of low-intensity extracorporeal shockwave therapy on vascular parameters and sexual function in patients with arteriogenic erectile dysfunction.

ABSTRACT: Previous published studies have shown an improvement of penile hemodynamic parameters after low-intensity extracorporeal shockwave therapy (Li-ESWT). However, the clinical significance of these findings remains unclear, and definitive selection criteria for Li-ESWT based on preexisting comorbidities have yet to be established. This was an observational study of 113 patients with ED, evaluated between January 2019 and December 2021 in Andrology Unit at the Department of Urology and Renal Transplantation, University of Foggia (Foggia, Italy). Penile dynamic Doppler was performed to evaluate vascular parameters and 5-item version of the International Index of Erectile Dysfunction (IIEF-5) questionnaire was administered to assess the severity of ED. This was repeated 1 month after treatment. Patients with a peak systolic velocity (PSV) <30 cm s-1 were considered eligible for Li-ESWT. Our protocol consisted of 8 weekly sessions with 1500 strokes distributed in 5 different locations along the penis. After treatment, a significant mean (±standard deviation [s.d.]) PSV increase of 5.0 (±3.4) cm s-1 was recorded and 52/113 (46.0%) patients reached a PSV >30 cm s-1 at posttherapeutic penile dynamic Doppler. A clinically significant IIEF-5 score improvement was observed in 7 patients, 21 patients, and 2 patients with mild-to-moderate, moderate, and severe pretreatment ED, respectively. No different outcomes were assessed based on smoking habits, previous pelvic surgery, or use of oral phosphodiesterase-5 inhibitor (PDE5i). On the other side, only 1 (6.7%) in 15 patients with diabetes mellitus showed an IIEF-5 score improvement after Li-ESWT. Shockwave treatment determined a significant increase in PSV and correlated IIEF-5 improvement in ED patients. This advantage seemed particularly evident for moderate ED and was not affected by smoking habits, previous pelvic surgery, and use of PDE5i. Conversely, diabetic patients did not benefit from the treatment.

Review of efficacy and safety of same-day discharge after percutaneous nephrolithotomy.

PURPOSE: Prior literature reviews have assessed the efficacy and safety of outpatient percutaneous nephrolithotomy (PCNL) with "outpatient" defined as discharge within twenty-four hours of surgery. To our knowledge, this is the first literature review analyzing ambulatory PCNLs (aPCNL) defined as hospital discharge on the same day as surgery. This review aims to assess the efficacy and safety of same-day discharge after PCNL. METHODS: We conducted a search in the PubMed database for key search terms including "ambulatory PCNL", "ambulatory percutaneous nephrolithotomy", "outpatient PCNL", "outpatient percutaneous nephrolithotomy", and "day surgery percutaneous nephrolithotomy". We reviewed articles defining "ambulatory" as discharge the same day the PCNL was performed. 13 papers were identified in our search. RESULTS: Overall, we found no difference in complication rates, emergency department visits, and postoperative admissions when comparing outpatient PCNL to inpatient PCNL, and to previously published statistics for inpatient PCNL. Some studies even showed lower rates of adverse outcomes in ambulatory cohorts when compared to inpatient cohorts. Additionally, ambulatory PCNL conferred significant healthcare savings over inpatient PCNL. CONCLUSION: This literature review suggests that ambulatory PCNL can be safely performed in both optimal and suboptimal surgical candidates with no significant increase in complications. Additional high-quality studies are warranted to further the evidence surrounding outpatient PCNL and its outcomes.

Comparison of metabolic parameters between pure-uric acid and mixed-uric acid kidney stone formers.

PURPOSE: We seek to compare clinical and 24-h urine parameters between pure-uric acid (UA) and UA-CaOx stone formers in our practice and explore how any differences in metabolic profiles could suggest different prevention strategies between the two groups. METHODS: We retrospectively reviewed patients with either pure- or mixed-UA nephrolithiasis from 2020 to 2023 at a tertiary care center. We included patients with a 24-h urine collection and a stone analysis detecting any amount of UA. Patients were organized into two cohorts: (1) those with 100% UA stones and (2) < 100% UA stones. Differences in demographic characteristics were compared between pure-UA and UA-CaOx stone formers. Twenty-four hour urine metabolic parameters as well as metabolic abnormalities were compared between the pure-uric acid and mixed-uric acid groups. RESULTS: We identified 33 pure-UA patients and 33 mixed-UA patients. Patient demographics were similar between the groups (Table 1). Pure- and mixed-UA patients had a similar incidence of metabolic syndrome, diabetes, history of stones, and stone burden. Table 1 Demographic and baseline characteristics among pure- and mixed-uric acid stone formers Pure-uric acid stones (n = 33) Mixed-uric acid stones (n = 33) p-value Median age [IQR] 63.00 [58.00-72.50] 63.00 [53.50-68.00] 0.339 Median BMI [IQR] 28.79 [25.81-33.07] 27.96 [25.81-29.55] 0.534 Gender, n (%) 1.000  Male 21 (63.6) 21 (63.6)  Female 12 (36.4) 12 (36.4) Metabolic syndrome, n (%) 17 (51.5) 16 (48.5) 0.806 Diabetes, n (%) 13 (39.4) 12 (36.4) 0.800 History of stones, n (%) 23 (69.7) 22 (66.7) 0.792 Median total stone burden, mm [IQR] 12.00 [6.00-26.50] 13.00 [7.05-20.00] 0.995 Median serum uric acid, mg/dL [IQR] 6.20 [4.80-7.15] 5.90 [4.98-6.89] 0.582 IQR Interquartile range BMI Body Mass Index n number We found the pure-UA cohort to have 24-h lower urine volume (1.53 vs. 1.96 L/day, p = 0.045) and citrate levels (286 vs. 457 mg/day, p = 0.036). UA-CaOx stone formers had higher urinary calcium levels (144 vs. 68 mg/day, p = 0.003), higher urinary oxalate levels (38 vs. 30 mg/day, p = 0.017), and higher median urinary calcium oxalate super-saturation (3.97 vs. 3.06, p = 0.047). CONCLUSIONS: Pure-UA kidney stone formers have different urinary metabolic parameters when compared with UA-CaOx stone formers, thus requiring different and tailored medical management.

Development and validation of 3-dimensional simulators for penile prosthesis surgery.

BACKGROUND: The acquisition of skills in penile prosthesis surgery has many limitations mainly due to the absence of simulators and models for training. Three-dimensional (3D) printed models can be utilized for surgical simulations, as they provide an opportunity to practice before entering the operating room and provide better understanding of the surgical approach. AIM: This study aimed to evaluate and validate a 3D model of human male genitalia for penile prosthesis surgery. METHODS: This study included 3 evaluation and validation stages. The first stage involved verification of the 3D prototype model for anatomic landmarks compared with a cadaveric pelvis. The second stage involved validation of the improved model for anatomic accuracy and teaching purposes with the Rochester evaluation score. The third stage comprised validation of the suitability of the 3D prototype model as a surgical simulator and for skill acquisition. The third stage was performed at 3 centers using a modified version of a pre-existing, validated questionnaire and correlated with the Rochester evaluation score. OUTCOME: We sought to determine the suitability of 3D model for training in penile prosthesis surgery in comparison with the available cadaveric model. RESULTS: The evaluation revealed a high Pearson correlation coefficient (0.86) between questions of the Rochester evaluation score and modified validated questionnaire. The 3D model scored 4.33 ± 0.57 (on a Likert scale from 1 to 5) regarding replication of the relevant human anatomy for the penile prosthesis surgery procedure. The 3D model scored 4.33 ± 0.57 (on a Likert scale from 1 to 5) regarding its ability to improve technical skills, teach and practice the procedure, and assess a surgeon's ability. Furthermore, the experts stated that compared with the cadaver, the 3D model presented greater ethical suitability, reduced costs, and easier accessibility. CLINICAL IMPLICATIONS: A validated 3D model is a suitable alternative for penile prosthesis surgery training. STRENGTHS AND LIMITATIONS: This is the first validated 3D hydrogel model for penile prosthesis surgery teaching and training that experts consider suitable for skill acquisition. Because specific validated guidelines and questionnaires for the validation and verifications of 3D simulators for penile surgery are not available, a modified questionnaire was used. CONCLUSION: The current 3D model for penile prosthesis surgery shows promising results regarding anatomic properties and suitability to train surgeons to perform penile implant surgery. The possibility of having an ethical, easy-to-use model with lower costs and limited consequences for the environment is encouraging for further development of the models.

Antioxidant treatment for oligoasthenoteratozoospermia and varicocele: a DBPC trial to evaluate the impact of age and body mass index.

ABSTRACT: Oxidative stress is one of the main mechanisms responsible for male infertility. Various conditions such as varicocele, obesity, advanced age, and lifestyle can lead to an increase in reactive oxygen species, causing an oxidative imbalance in the reproductive environment. Spermatozoa are sensitive to reactive oxygen species and require energy to carry out their main function of fertilizing the egg. Excessive reactive oxygen species can affect sperm metabolism, leading to immobility, impaired acrosome reaction, and cell death, thereby impairing reproductive success. This double-blind randomized study evaluated the effect of supplementation with L-carnitine, acetyl-L-carnitine, vitamins, and other nutrients on semen quality in 104 infertile patients with or without varicocele, while also investigating the impact of factors such as obesity and advanced age on treatment. Sperm concentration significantly increased in the supplemented group compared to the placebo group (P = 0.0186). Total sperm count also significantly increased in the supplemented group (P = 0.0117), as did sperm motility (P = 0.0120). The treatment had a positive effect on patients up to 35 years of age in terms of sperm concentration (P = 0.0352), while a body mass index (BMI) above 25 kg m-2 had a negative effect on sperm concentration (P = 0.0110). Results were not showing a net benefit in stratifying patients in accordance with their BMI since sperm quality increase was not affected by this parameter. In conclusion, antioxidant supplementation may be beneficial for infertile patients and has a more positive effect on younger patients with a normal weight.

Penoscrotal approach for inflatable penile prosthesis implant: why it should be preferred.

INTRODUCTION: Inflatable penile prosthesis are the definitive treatment for erectile dysfunction. The two most used surgical approaches to position the implants are the penoscrotal and the infrapubic. Current trends showed that the penoscrotal approach is extensively preferred however, there is not conclusive evidence demonstrating the superiority of one technique over the other. The aim of this review is to summarize the scientific evidence available and to underline strengths and weaknesses of the two techniques. EVIDENCE ACQUISITION: We conducted a comprehensive search of MEDLINE, Cochrane Library, and National Center for Biotechnology Information PubMed to identify relevant published articles. The included studies had to explicitly examine the use of three-piece inflatable penile prosthesis with a focus on the surgical access method and complications. EVIDENCE SYNTHESIS: Twenty-six articles were included in the review: seven narrative reviews, five retrospective observational studies, five prospective observational studies, and nine mixed methodology studies. The most frequent approach was the penoscrotal, which was also found more comfortable (RG1) by the operators in one study. The infrapubic approach lasts less and one study demonstrated higher satisfaction by the patients. CONCLUSIONS: There is no evidence of significant differences in complications among the penoscrotal and infrapubic approaches. While the infrapubic approach is faster and patients were more satisfied, the penoscrotal approach is the most used by far. This is likely related to the more straightforward procedure through this access and the excellent surgical field exposure. For these reasons, it is also preferred in the most complex cases.

Comprehensive analysis of factors associated with significant blood loss during percutaneous nephrolithotomy.

INTRODUCTION: The objective of this study is to conduct a thorough investigation of the risk factors associated with blood loss during PCNL, within the setting of a US urban tertiary care center. MATERIALS AND METHODS: We conducted a retrospective analysis of our endourology database to identify adult patients who underwent PCNL for stone extraction at our tertiary stone center between October 2014 and December 2022. Patients were categorized into two groups based on the extent of blood loss: significant blood loss (SBL) and no significant blood loss (NSBL). The cut-off value for SBL was determined as the median change in hematocrit levels from preoperative to postoperative among patients who required postoperative transfusions. Several factors were evaluated, including stone dimensions, operative details, the presence of preoperative drains, patient position, type of access, access site, number of accesses, tract size, tract length, stone location, number of stones, operative time, and the S.T.O.N.E. Nephrolithometry Scoring System. RESULTS: Our analysis included a total of 695 procedures performed on 674 distinct patients who met our inclusion criteria. Of these, 102 patients (14.7%) were included in the SBL group. Patients in the SBL group had a higher mean number of accesses (1.57 vs. 1.29, P<0.001), were positioned prone more often (96.0% vs. 88.6%, P = 0.025), and underwent fluoroscopic-guided access more frequently (89.9% vs. 64.8%, P<0.001). Additionally, significant differences were observed in stone morphology, with the SBL group having higher rates of complete staghorn stones (42.2% vs. 27.0%, P = 0.019) and lower rates of partial staghorn stones (27.7% vs. 36.8%, P = 0.019). A larger proportion of patients in the SBL group required a 16 French nephrostomy tube for postoperative drainage (13.3% vs. 10.4%, P = 0.041). Lastly, the SBL group had a longer mean operative time compared to the NSBL group (P<0.001). Multiple logistic regression analysis identified stone volume (P = 0.039), number of accesses (P = 0.047), and operative time (P = 0.006) as independent risk factors associated with SBL status. CONCLUSION: Surgical complexity factors such as stone volume, number of accesses, and operative time are linked to a higher risk of SBL during PCNL. Stone volume and the requirement for multiple accesses can usually be estimated with reasonable accuracy before surgery.

Diagnosis of prostate cancer with magnetic resonance imaging in men treated with 5-alpha-reductase inhibitors.

PURPOSE: The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade ≥ 2). METHODS: This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients. RESULTS: 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naïve (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p < 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG ≥ 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS ≥ 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively. CONCLUSIONS: Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions. TRIAL REGISTRATION: The present study was registered at ClinicalTrials.gov number: NCT05078359.

Drivers of calcium oxalate stone formation in the octogenarian population.

INTRODUCTION: American Urological Association (AUA) guidelines suggest metabolic testing via 24-h urine studies in high-risk, interested first-time stone formers, and recurrent stone formers. If metabolic testing is not available or otherwise not feasible, clinicians may need to utilize empiric therapy. Debility and social barriers, particularly in the elderly population, may limit the practicality of metabolic testing, and therefore, empiric therapy is of particular importance. The aim of this study is to identify whether unique urinary metabolic abnormality profiles exist for octogenarians with calcium oxalate kidney stones, as this may guide empiric stone prevention therapy more precisely in this population. MATERIALS AND METHODS: Patients with calcium oxalate stones from a single academic kidney stone center in New York, NY, were retrospectively identified in our prospectively managed database. Patient data, including demographic, clinical information, and baseline 24-h urine studies, were collected before initiating any treatment. Subjects were stratified by age (≤ 40, 41-59, 60-79, and ≥ 80 years) to compare the metabolic urinary abnormality profiles between octogenarians and other age groups. Subgroup analyses were also performed to compare results by gender and by the presence of underlying kidney dysfunction. Comparative statistical analysis was carried out using Chi-square tests, Mann-Whitney U tests, and t-tests where appropriate. RESULTS: Hypocitraturia, low urine pH, and low urine volume were most common in older patients, particularly in octogenarians. Hypercalciuria, hypernatriuria, and hyperuricosuria were more apparent in younger groups. CONCLUSION: With increasing age, hypocitraturia, low urine pH, and low urine volume were more prevalent on 24-h urine metabolic testing. We hypothesize increased comorbidity, including medical renal disease, polypharmacy, and dehydration are possible factors contributing to this unique profile. We suggest that empiric therapy targeted towards this profile is important in very elderly stone formers in whom 24-h urine testing may not be possible. Increased hydration, increased fruit and vegetable intake, and low-dose alkali therapy are easy measures to accomplish this.

Adjuvant intraluminal therapies for upper tract urothelial carcinoma.

Upper urinary tract urothelial carcinomas (UTUCs) are often identified and first treated endoscopically. After proper risk stratification, adjuvant treatment may be recommended. Consequently, as adjuvant therapy becomes more common place in the oncological armamentarium, we seek to better characterize its existing and future therapeutic landscape. In this article, we present an overview of the most up-to-date information about intracavitary instillations as an adjuvant therapy in the context of UTUC. We reviewed the current literature on the epidemiology, disease characteristics, treatment, and outcomes of UTUC with a particularly focus on intraluminal adjuvant therapy for UTUC. This review provides a comprehensive overview of the most recent available data regarding adjuvant therapies used for UTUC. Intraluminal therapy plays an increasingly important role in the management of UTUC. Mitomycin C is the most common adjuvant treatment for UTUC with bacillus Calmette-Guerin (BCG) being utilized to a lesser extent. UGN-101 is a novel topical gel-based therapy that has shown promising results and thus recently garnered Food and Drug Administration (FDA) approval for UTUC. Other treatments such as BCG-IFN, gemcitabine, docetaxel, and drug-eluting stents (DES) may play a future role in UTUC treatment given further research. It is important to caveat that current studies on topical adjuvant treatments demonstrate varying degrees of effectiveness. This is largely due to limited research on UTUC, consisting of small sample sizes, and mostly retrospective experiences. Accordingly, further clinical trials are needed to evaluate the true benefit of these treatments.

External Validation of the IMPROD-MRI Volumetric Model to Predict the Utility of Systematic Biopsies at the Time of Targeted Biopsy.

Background: The aim of this study was to validate externally a nomogram that relies on MRI volumetric parameters and clinical data to determine the need for a standard biopsy in addition to a target biopsy for men with suspicious prostate MRI findings. Methods: We conducted a retrospective analysis of a prospectively maintained database of 469 biopsy-naïve men who underwent prostate biopsies. These biopsies were guided by pre-biopsy multiparametric Magnetic Resonance Imaging (mpMRI) and were performed at two different institutions. We included men with a PIRADSsv 2.1 score from 3 to 5. Each patient underwent both an MRI-ultrasound fusion biopsy of identified MRI-suspicious lesions and a systematic biopsy according to our protocol. The lesion volume percentage was determined as the proportion of cancer volume on MRI relative to the entire prostate volume. The study's outcomes were iPCa (Gleason Grade Group 1) and csPCa (Gleason Grade Group > 1). We evaluated the model's performance using AUC decision curve analyses and a systematic analysis of model-derived probability cut-offs in terms of the potential to avoid diagnosing iPCa and to accurately diagnose csPCa. Results: The nomogram includes age, PSA value, prostate volume, PIRADSsv 2.1 score, percentage of MRI-suspicious lesion volume, and lesion location. AUC was determined to be 0.73. By using various nomogram cut-off thresholds (ranging from 5% to 30%), it was observed that 19% to 58% of men could potentially avoid undergoing standard biopsies. In this scenario, the model might miss 0% to 10% of diagnosis of csPCa and could prevent identifying 6% to 31% of iPCa cases. These results are in line with findings from the multi-institutional external validation study based on the IMPROD trial (n = 122) and the MULTI-IMPROD trial (n = 262). According to DCA, the use of this nomogram led to an increased overall net clinical benefit when the threshold probability exceeded 10%. Conclusions: This study supports the potential value of a model relying on MRI volumetric measurements for selecting individuals with clinical suspicion of prostate cancer who would benefit from undergoing a standard biopsy in addition to a targeted biopsy.

Selecting an Endourology Society Fellowship Program: The Candidates' Perspectives.

Introduction: Understanding the factors that influence the decision of urology residents to pursue an Endourology Society (ES) fellowship and the criteria used by applicants to rank programs may help residents and program directors (PDs) optimize the match process. In the present study, we surveyed current ES fellows to gain better insight surrounding their decision-making process. Materials and Methods: A survey was emailed to all ES fellows, comprising Endourology and Stone Disease (ESD), Laparoscopic and Robotic Surgery (MIS), and combination of ESD/MIS (COM) programs. A Likert scale ranging from 1 to 5 was used. The survey captured demographics such as geographic region, program type, duration, applicants' reasons for pursuing fellowship, criteria for ranking programs, and perceived improvements in surgical comfort levels at the end of their training. Results: Out of the 60 fellows who were surveyed, 40 (66.7%) responded. Among the respondents, 9 (22.5%) pursued ESD, 10 (25%) pursued MIS, and 21 (52.5%) pursued COM programs. The primary reason for seeking a fellowship was to improve surgical skills while increasing earning potential and enhancing research opportunities were deemed the least important. Fellows enrolled in 1-year programs were less likely to pursue fellowships for academic reasons. The two most significant factors in selecting a program were both related to gaining operative experience. Lastly, there was an increase in the level of comfort performing all endourological surgeries independently after fellowship. Conclusions: ES fellowship is seen as an opportunity to hone surgical skills and increase job competitiveness. When selecting a program, operative experience is the most important factor, and fellowship improves operative confidence. The information obtained from this study may mutually help guide future applicants and PDs in the decision process of the Endourology Match.

Opioid-free percutaneous nephrolithotomy: an initial experience.

INTRODUCTION: The opioid epidemic in the United States is an ongoing public health crisis that is in part fueled by excessive prescribing by physicians. Percutaneous nephrolithotomy (PCNL) is a procedure that conventionally involves opioid prescriptions for adequate post-operative pain control. We aimed to evaluate the feasibility of a non-opioid pain regimen by evaluating post-operative outcomes in PCNL patients discharged without opioids. MATERIALS AND METHODS: As a quality improvement measure to reduce opioid consumption our department began routinely prescribing oral ketorolac instead of oxycodone-acetaminophen for pain control after PCNL. We retrospectively compared patients undergoing PCNL who had received ketorolac prescriptions (NSAID) to those who received oxycodone-acetaminophen prescriptions (NARC). Demographic, operative, and post-operative factors were obtained and compared in both groups. Peri-operative factors and demographics were compared using either Chi-squared tests, Mann-Whitney U tests. Surgical outcomes were compared between the two groups using Chi-squared tests and Fisher's exact tests. Multivariate logistic regression analysis was performed to determine whether ketorolac use was an independent predictor of post-surgical pain-related encounters. Primary outcome was unplanned pain-related healthcare encounters inclusive of office phone calls, unscheduled office visits, and emergency department (ED) visits. Secondary outcome measures were non-pain-related healthcare encounters, hospital readmissions, pain-related rescue medications prescribed, and post-op complications. RESULTS: There were similar demographics and peri-operative characteristics amongst patients in both cohorts. There was no significant difference identified between NSAID and NARC regarding unplanned pain-related encounters (8/70, 11.4% vs. 10/70, 14.3%, p = 0.614). However, NARC experienced more unplanned phone calls (42, 60% vs. 24, 34.3%, p = 0.004). Multivariate analysis revealed only prior stone surgery was predictive of pain-related encounters after PCNL (p = 0.035). CONCLUSION: Our results show that there were no significant differences in pain-related encounters between those who received ketorolac and oxycodone-acetaminophen following PCNL. A non-opioid pathway may mitigate the potential risk associated with opioid prescription without compromising analgesia. Prospective comparative studies are warranted to confirm feasibility.

The effects of continuing aspirin on blood loss and postoperative outcomes in percutaneous nephrolithotomy.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is an effective surgery for complex kidney stones yet with inherent bleeding risks. It remains unclear whether aspirin should be discontinued prior to PCNL. We aimed to further substantiate the safety of continuing aspirin during PCNL surgery and to determine whether aspirin status affects postoperative outcomes following PCNL. METHODS: We retrospectively queried our endourology database for patients who underwent PCNL from October 2017 to December 2022 at our high-volume tertiary referral center. The three groups were based on aspirin status at the time of PCNL: no aspirin (NA), discontinued aspirin (DA), and continued aspirin (CA). Data collected included demographics, preoperative characteristics, operative parameters, pre and postoperative lab values, transfusions, and complications. RESULTS: A total 648 patients were divided into these study groups: 525 NA patients (81.0%), 55 DA (8.5%), and 68 CA (10.5%). The DA and CA groups were of similar comorbidities, and both were more comorbid at baseline than NA. Postoperative change in lab values and complications did not differ significantly. Rates of postoperative blood transfusion were higher in the CA and DA groups compared to NA and approached statistical significance. There were no significant differences in any postoperative outcomes between the DA and CA groups alone. CONCLUSIONS: In patients on chronic aspirin therapy, continuing aspirin appears equally safe to discontinuing aspirin prior to PCNL. Most patients should not forego the benefits of continuous aspirin for the theoretical risk of bleeding. Patients on prolonged aspirin therapy may be more likely than those who are not on chronic aspirin therapy to require blood transfusions. However, regardless of whether aspirin use is stopped, this may be caused by patient comorbidities rather than higher rates of blood loss.

Male esthetic genital surgery: recommendations and gaps to be filled.

The reason behind the spread of penis enlargement practices over time is rooted in the virility that the appearance of the genitals can give a man, as well as an altered perception of his own body. The approach should be to modulate the interventions on the real needs of patients, carefully evaluating the history, the psychological picture, and possible surgical advantages. The aim of this study was to shed light on cosmetic surgery of male genitalia through minimally invasive and more radical techniques, with the purpose of laying the foundation for possible indications and recommendations for the future. A non-systematic literature review using the PubMed and Scopus databases was conducted to retrieve papers written in English on cosmetic surgery of the penis published over the past 15 years. Papers discussing cosmetic surgery in patients with concomitant pathologies associated with sexual dysfunction were excluded. The main outcomes recorded were change in penile dimensions in term of length and girth and surgical complications.
