Robot-Assisted Radical Prostatectomy in PIRADS 5 Lesions Without Prior Biopsy: Is Biopsy Really Necessary in This Cohort?

Introduction: Conventionally, confirmation of clinically significant prostate cancer (csPCa) (Gleason grade group ≥ 2) involves an initial multiparametric magnetic resonance imaging (mpMRI) followed by biopsy. Prostate biopsy incurs inherent risks of infection, bleeding, patient discomfort, and a 6-week delay before robot-assisted laparoscopic radical prostatectomy (RALP). We explored the feasibility of immediate RALP in men with PIRADS 5 lesions without preceding biopsy. Methodology: After obtaining institutional review board approval, a prospective analysis was conducted on 235 patients with PIRADS 5 lesions on mpMRI from December 2018 to February 2023. Patients were divided into 2 groups as follows: Group NoBiopsy (biopsy not done before RALP, cases, n = 118) and Group YesBiopsy (biopsy done before RALP, controls, n = 117). Baseline preoperative, intraoperative, and postoperative parameters were analyzed. Functional outcomes were monitored at 1, 3-, 6-, 9-, and 12-months follow-up post-RALP. Statistical analysis was performed using SPSS and STATA. Results: Ninety-five percent of cases and 87.17% controls had csPCa on final pathology post-RALP. Multivariable analysis did not find significant association between biopsy status and csPCa. Abnormal digital rectal examination (DRE), family history, preoperative PSA, and MRI lesion volume predicted csPCa. Significant differences were observed in console time (NoBiopsy vs. YesBiopsy, 60 ± 10 vs. 70 ± 9 minutes, p < 0.001) and estimated blood loss (80 ± 20 vs. 100 ± 30 mL, p < 0.01) between groups. At 6 months post-RALP, 96% of men in Group NoBiopsy were continent, compared with 88% of men in Group YesBiopsy (p < 0.04). All men in the study cohort were continent (0 pads) at 12 months post-RALP. Ninety-eight percent of cases and 92% of controls at 9 months and 12 months, respectively, were able to have penetrative sex with or without PDE-5 inhibitors post-RALP. Conclusion: RALP without antecedent prostate biopsy in men with PIRADS 5 lesions demonstrated substantial csPCa detection rates and superior functional outcomes, warranting further validation.

Comparison of lateral flank approach and low anterior access for single port (SP) retroperitoneal partial nephrectomy: an analysis from the single port advanced research consortium (SPARC).

Single Port (SP) robotic partial nephrectomy (RPN) can be performed via retroperitoneal and transperitoneal approach. We aim to compare outcomes of two commonly described incisions for retroperitoneal SP RPN: lateral flank approach (LFA) and low anterior access (LAA). We performed a retrospective study of patients who underwent SP retroperitoneal RPN from 2018 to 2023 as part of a large multi-institute collaboration (SPARC). Baseline demographic, clinical, tumor-specific characteristics, and perioperative outcomes were compared using χ2, t test, Fisher exact test, and Mann-Whitney U test. Multivariable analyses were conducted using robust and logistic regressions. A total of 70 patients underwent SP retroperitoneal RPN, with 44 undergoing LAA. Overall, there were no significant differences in baseline characteristics between the two groups. The LAA group exhibited significantly lower median RENAL scores (8 vs. 5, p < 0.001) and more varied tumor locations (p = 0.002). In the bivariate analysis, there were no statistically significant differences in ischemia time, estimated blood loss, or complication rates between the groups. However, the LAA group had longer operative times (101 vs. 134 min, p < 0.001), but was more likely to undergo a same-day discharge (p < 0.001). When controlling for other variables, LAA was associated with shorter ischemia time (p = 0.005), but there was no significant difference in operative time (p = 0.348) and length of stay (p = 0.122). Both LFA and LAA are acceptable approaches for SP retroperitoneal RPN with comparable perioperative outcomes. This early data suggests the LAA is more versatile for varying tumor locations; however, larger cohort studies are needed to ascertain whether there is an overall difference in patient recovery.

Prostate Cancer Incidence and Mortality in Men Exposed to α1-Adrenoceptor Antagonists.

BACKGROUND: α1-antagonists are commonly used to treat benign prostatic hyperplasia. Preclinical studies suggest they induce cell death and inhibit tumor growth. This study evaluates the risk of prostate cancer death in men using α1-antagonists. METHODS: A population-based cohort study in Stockholm, Sweden (January 1, 2007 to December 31, 2019) including 451,779 men with a prostate-specific antigen (PSA) test. Study entry was one year after the first PSA test. Men were considered exposed at their second filled prescription. Primary outcome: prostate cancer mortality. Secondary outcomes: all-cause mortality and prostate cancer incidence. Cox proportional hazard regression models were used to calculate adjusted hazard ratios (HRs) and 95% CIs for all outcomes. Inverse probability weighting with marginal structural models accounted for time-dependent confounders. RESULTS: Of 351,297 men in the cohort, 39,856 (11.3%) were exposed to α1-antagonists. Median follow-up for prostate cancer mortality was 8.9 years and median exposure time to α1-antagonists was 4.4 years. There was no evidence of an association between α1-antagonist use and prostate cancer mortality, all-cause mortality, or high-grade prostate cancer. α1-antagonist-use was associated with an increased risk of prostate cancer (HR: 1.11, 95% CI: 1.06-1.17) and low-grade prostate cancer (HR: 1.22, 95% CI: 1.11-1.33). Men treated with α1-antagonists had more frequent PSA testing. CONCLUSIONS: Our findings show no significant association between α1-adrenoceptor antagonist exposure and prostate cancer mortality or high-grade prostate cancer. Although the preclinical evidence indicates a potential chemopreventive effect, this study's findings do not support it.

A multi-institutional update on surgical outcomes after penile silicone sleeve implantation.

Background: The increasing popularity of the silicone sleeve penile implant has been accompanied by concerns over potential risks and adverse events. Objectives: To provide multi-institutional data on safety outcomes in patients undergoing silicone sleeve penile implant surgery across high-volume implant surgeons. In addition, we discuss preventative techniques to minimize postoperative complications and the management of these events. Design and methods: We performed a retrospective analysis of men undergoing penile silicone sleeve implants between November 2020 and November 2022 with four surgeons, each from a separate institution. Perioperative and postoperative adverse events, including unsatisfactory cosmetic outcomes requiring revision, were determined by physician follow-up. Flaccid penile length and girth were measured preoperatively and postoperatively. Results: A total of 299 male patients underwent silicone sleeve implant surgery, with an average age of 42.5 ± 10.5 years and an average body mass index of 28.5 ± 4.0. The patient cohort exhibited minimal comorbidities, with 5% having hyperlipidemia, 2% being smokers, 2% having cardiovascular disease, and 1% having diabetes. Patients experienced an average increase of 4.1 ± 1.5 cm in their flaccid penile length (a 50% increase) and an average increase of 3.4 ± 1.5 cm in their flaccid girth (a 37% increase) (p < 0.01). Complication rates included new-onset postoperative erectile dysfunction (0%), infection (1.3%), seroma (2.0%), and erosion (5.0%). The average follow-up time was 11.6 months. Notably, our rates of infection and seroma were lower than those reported in a previous single-center review, while erosion rates were higher. Conclusion: This is the largest study to characterize the safety of the penile silicone sleeve implant across multiple institutions. In men who desire cosmetic size augmentation, silicone sleeve implant surgery is associated with significantly increased flaccid penile length and girth. Complications are mainly cosmetic and may be corrected; however, patients should be appropriately counseled on the risk of erosion, which appears to be higher than previously reported.

Robotic nephroureterectomy supplanting open and laparoscopic approach for upper tract urothelial carcinoma management: a narrative review.

Background and Objective: The use of robotic surgery for managing upper tract urothelial carcinoma (UTUC) has increased significantly over the years. Minimally invasive techniques (MIS) are now used for approximately half of all robot-assisted laparoscopic nephroureterectomy (RAL-NU) performed in the USA. However, there are currently no specific management guidelines that recommend the use of a robotic approach, and the available literature on this topic is limited. For this reason, we reviewed the history and current literature regarding this technique. Methods: We searched Web of Science and PubMed for articles between 1934 to 2023 using 20 different search terms and combinations. We restricted our selection to only publications in English language. Key Content and Findings: Comparative retrospective studies between techniques [open nephroureterectomy (ONU), laparoscopic nephroureterectomy (LNU), and RAL-NU] and case series of surgical groups, mostly at short- and mid-term follow-up, were included. Conclusions: Robotic surgery for UTUC is on the rise and is predicted to become the preferred method for nephroureterectomy. A comparison of RAL-NU to LNU and ONU shows several advantages, including less blood loss, pain, and hospital stay, as well as a quicker recovery time. The safety and effectiveness of robotic surgery for lymphadenectomy also supports its use in RAL-NU. As more medical facilities adopt the technique and further studies support its benefits, it is likely that robotic surgery will become the preferred method for NU.

Assessing ChatGPT's ability to answer questions pertaining to erectile dysfunction: can our patients trust it?

Erectile dysfunction (ED) is a disorder that can cause distress and shame for men suffering from it. Men with ED will often turn to online support and chat groups to ask intimate questions about their health. ChatGPT is an artificial intelligence (AI)-based software that has been trained to engage in conversation with human input. We sought to assess the accuracy, readability, and reproducibility of ChatGPT's responses to frequently asked questions regarding the diagnosis, management, and care of patients with ED. Questions pertaining to ED were derived from clinic encounters with patients as well as online chat forums. These were entered into the free ChatGPT version 3.5 during the month of August 2023. Questions were asked on two separate days from unique accounts and computers to prevent the software from memorizing responses linked to a specific user. A total of 35 questions were asked. Outcomes measured were accuracy using grading from board certified urologists, readability with the Gunning Fog Index, and reproducibility by comparing responses between days. For epidemiology of disease, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 100% across both days. There was fair reproducibility and median readability of 15.9 (IQR 2.5). For treatment and prevention, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 78.9%. There was poor reproducibility of responses with a median readability of 14.5 (IQR 4.0). Risks of treatment and counseling both had 100% of questions graded as "comprehensive" or "correct but inadequate." The readability score for risks of treatment was median 13.9 (IQR 1.1) and for counseling median 13.8 (IQR 0.5), with good reproducibility for both question domains. ChatGPT provides accurate answers to common patient questions pertaining to ED, although its understanding of treatment options is incomplete and responses are at a reading level too advanced for the average patient.

One-year healthcare costs after robotic-assisted and laparoscopic partial and radical nephrectomy: a cohort study.

OBJECTIVE: Despite the wide-spread adoption of robotic-assisted surgery (RAS), the cost-benefit implications for partial (PN) and radical nephrectomy (RN) versus laparoscopic surgery (Lap) is not well established. We sought to examine the trend of adoption and 1-year healthcare expenditure of PN and RN, and compare 1-year expenditures of RAS versus Lap for PN and RN. PATIENTS AND METHODS: This cohort study used the MerativeTM MarketScan® Databases between 2013 and 2020. A total of 5,353 patients with kidney cancer undergoing PN (2,980, 55.7%) or RN (2,373, 44.3%). We compared open-conversion, length of stay (LOS), index expenditure, 1-year healthcare expenditure and utilization, and missed work-days between RAS and Lap for PN and RN. RESULTS: Adoption of PN increased overtime (47.0% to 55.8%), mainly driven by robotic PN increase. Among PN, RAS had lower open-conversion, shorter LOS and lower index expenditure than Lap. Among RN, RAS had shorter LOS, and similar open-conversion and index expenditures. During 1-year post-discharge, RAS had lower hospital outpatient visits (IRR = 0.92, 95% CI = 0.85, 0.99, p = 0.029) and office-based visits (IRR = 0.91, 95% CI = 0.86, 0.96, p = 0.002) for PN, translating to a 1-day less (95% CI = 0.25, 1.75, p = 0.008) missed from work for RAS. Following RN, RAS had lower 1-year readmission than Lap (O.R = 0.72, 95% CI = 0.55, 0.94, p = 0.018). RAS and Lap had comparable 1-year post-discharge expenditures for both PN (mean difference, MD = -$475, 95% CI = -$4362, $3412, p = 0.810) and RN (MD = -$4,204, 95% CI = -$13,837, $5430, p = 0.404). CONCLUSION: At index surgery, RAS was associated with shorter LOS for both PN and RN, and lower open-conversion and expenditures for PN. RAS and Lap had comparable 1-year total expenditures, despite lower healthcare visits for RAS.

Impact of exercise on continence in prostate cancer patients post robotic assisted radical prostatectomy: a systematic review.

INTRODUCTION: Urinary incontinence is one of the most common long term side effects after robotic prostatectomy (RALP), and significantly impacts patient quality of life. Pelvic floor muscle training (PFMT) has been a standard part of the urologist's armamentarium for maximizing continence outcomes post-op. Recently, aerobic and resistance exercises have been described as improving functional outcomes post RALP. We performed a systematic review to determine the influence of exercise, in the form of PFMT, aerobic exercise, and resistance training, on incontinence post-RALP. MATERIALS AND METHODS: This systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with database searches performed on January 14, 2022 and again on August 10, 2022 to account for any new publications. The search identified 1675 papers. Of the 1675 papers, 1007 were found to be duplicates, leaving 668 total studies for screening. Of the 668 papers, nine met all inclusion criteria. Of the nine, four studies presented data from patients who had undergone RALP and were included in the final descriptive systematic review. RESULTS: Sayilan et al. and Milios et al. showed postoperative PFMT and physical activity resulted in significantly improved continence outcomes at 1 and 6 months and 2, 6, and 12 weeks postoperatively, respectively. Heydenreich et al. combined PFMT with an oscillating rod therapy, which was found to significantly improve both postoperative urinary continence and health related quality of life compared to PFMT and relaxation techniques alone. On the contrary, Goode et al. examined delivery of exercise information and demonstrated no difference in continence outcomes between focused telehealth PFMT program and generic prostate cancer education. CONCLUSION: Pelvic floor muscle training, with or without adjunct therapies, results in improved continence outcomes post RALP. Supervised training programs may or may not accelerate this finding. There is no recent literature to support or refute the benefit of aerobic exercise or resistance training on reducing post-prostatectomy incontinence after RALP.

Transperitoneal Versus Retroperitoneal Single-port Robotic-assisted Partial Nephrectomy: An Analysis from the Single Port Advanced Research Consortium.

BACKGROUND: In the surgical management of kidney tumors, such as in multiport technology, single-port (SP) robotic-assisted partial nephrectomy (RAPN) can be performed using the transperitoneal (TP) or retroperitoneal (RP) approach. However, there is a dearth of literature on the efficacy and safety of either approach for SP RAPN. OBJECTIVE: To compare the peri- and postoperative outcomes of the TP and RP approaches for SP RAPN. DESIGN, SETTING, AND PARTICIPANTS: This is a retrospective cohort study using data from the Single Port Advanced Research Consortium (SPARC) database of five institutions. All patients underwent SP RAPN for a renal mass between 2019 and 2022. INTERVENTION: TP versus RP SP RAPN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Baseline characteristics, and peri- and postoperative outcomes were compared between both the approaches using χ2 test, Fisher exact test, Mann-Whitney U test, and Student t test. RESULTS AND LIMITATIONS: A total of 219 patients (121 [55.25%] TP, 98 [44.75%] RP) were included in the study. Of them, 115 (51.51%) were male, and the mean age was 60 ± 11 yr. RP had a significantly higher proportion of posterior tumors (54 [55.10%] RP vs 28 [23.14%] TP, p < 0.001), while other baseline characteristics were comparable between both the approaches. There was no statistically significant difference in ischemia time (18 ± 9 vs 18 ± 11 min, p = 0.898), operative time (147 ± 67 vs 146 ± 70 min, p = 0.925), estimated blood loss (p = 0.167), length of stay (1.06 ± 2.25 vs 1.33 ± 1.05 d, p = 0.270), overall complications (5 [5.10%] vs 7 [5.79%]), and major complication rate (2 [2.04%] vs 2 [1.65%], p = 1.000). No difference was observed in positive surgical margin rate (p = 0.472) or delta eGFR at median 6-mo follow-up (p = 0.273). Limitations include retrospective design and no long-term follow-up. CONCLUSIONS: With proper patient selection based on patient and tumor characteristics, surgeons can opt for either the TP or the RP approach for SP RAPN, and maintain satisfactory outcomes. PATIENT SUMMARY: The use of a single port (SP) is a novel technology for performing robotic surgery. Robotic-assisted partial nephrectomy (RAPN) is a surgery to remove a portion of the kidney due to kidney cancer. Depending on patient characteristics and surgeons' preference, SP can be performed via two approaches for RAPN: through the abdomen or through the space behind the abdominal cavity. We compared outcomes between these two approaches for patients receiving SP RAPN, finding that they were comparable. We conclude that with proper patient selection based on patient and tumor characteristics, surgeons can opt for either the TP or the RP approach for SP RAPN, and maintain satisfactory outcomes.

Robot-assisted partial nephrectomy for complex renal tumors: Analysis of a large multi-institutional database.

INTRODUCTION: Highly complex renal masses pose a challenge to urologic surgeons' ability to perform robotic partial nephrectomy (RPN). Given the increased utilization of the robotic approach for small renal masses, we sought to characterize the outcomes and determine the safety and feasibility of RPN for complex renal masses from our large multi-institutional cohort. METHODS: We performed a retrospective analysis of patients with R.E.N.A.L. Nephrometry Scores ≥10 who underwent RPN in our multi-institutional cohort (N = 372). Baseline demographic, clinical and tumor related characteristics were evaluated with the primary endpoint of trifecta achievement (defined as negative surgical margin, no major complications, and warm ischemia time ≤25 min). Relationships between variables were assessed using the chi-square test of independence, Fisher exact test, Mann-Whitney U test, and Kruskal Wallis test. Logistic regression was used to evaluate the relationship between baseline characteristics and trifecta achievement. RESULTS: Of 372 patients in the study, mean age was 58 years, and median BMI was 30.49 kg/m2. The median tumor size was 4.3 cm (3.0-5.9 cm). Most of the patients had R.E.N.A.L. scores of 10 (n = 253; 67.01%). Overall, trifecta was achieved in 72.04% of patients. Stratifying intraoperative and postoperative outcomes by R.E.N.A.L. scores, there was no significant difference in trifecta achievement, operative time, warm ischemia time (WIT), open conversion, major complication, or positive margin rates. Length of hospital stay was significantly longer for higher R.E.N.A.L. scores (median days 2 vs. 1, P = 0.012). Multivariate analyses for factors associated with trifecta achievement concluded that age and baseline eGFR were independently associated with trifecta achievement. CONCLUSION: RPN is a safe and reproducible procedure for complex tumors with R.E.N.A.L. Nephrometry scores ≥10. Our results suggest excellent rates of trifecta achievement and short-term functional outcomes when performed by experienced surgeons. Long-term oncological and functional evaluation are needed to further support this conclusion.

Three piece penile prosthesis salvage with chlorhexidine gluconate and length preservation: our technique and outcomes.

OBJECTIVE: Since the advent of the Mulcahy technique of three-piece inflatable penile prosthesis (IPP) salvage, there have been multiple iterations of salvage prosthesis procedures reported in the literature. All of these techniques employ traditional antibiotic irrigation with or without rechanneling. We present our technique of salvage IPP using 0.05% chlorhexidine gluconate (Irrisept®) with corporal rechanneling for length preservation. MATERIALS AND METHODS: Our technique of IPP salvage begins with access via a 5 cm vertical midline scrotal incision. Dissection down to the corpora is performed with a combination of blunt dissection and dissection with fine tipped Metzenbaum scissors. Each component of the prior IPP is sequentially removed starting with the cylinders, followed by the pump, and finally the reservoir. Irrisept® is used to copiously irrigate out both cavernosal bodies as well as the scrotal compartment and prior reservoir location. A two minute dwell time of the Irrisept® is employed after mechanical irrigation. A penrose drain is placed from the space of Retzius through a separate stab incision in the scrotum. Corporotomies are closed, followed by Dartos fascia and scrotal skin. A complete change in gown and gloves of all members of the surgical team and a new set of drapes and instruments is performed. Through a separate subcoronal incision, two new corporotomies are made and separate channels created using nine inch Metzenbaum scissors. These channels are irrigated with Irrisept®. A 9 mm malleable penile prosthesis (MPP) is inserted and corporotomies and skin incision are closed. RESULTS: A total of four men with prior penoscrotal IPP placement underwent salvage IPP with MPP from January 2022 to October 2022. Median operative time was 165 minutes. Median preoperative cylinder size was 23.5 cm. Median postoperative malleable cylinder size was 23 cm. Median length of follow up was 4.8 months. There were no cases of MPP erosion or infection. Two patients elected to undergo repeat IPP insertion after 6 months with same cylinder size. CONCLUSION: IPP salvage with chlorhexidine irrigation and soak as well as separate corporal channeling in a noninfected field for MPP insertion is a viable strategy for infected prostheses given the ease of performance, low risk of repeat infection of the malleable device, and maintenance of corporal length of any subsequent prostheses.

Robot assisted laparoscopic radical prostatectomy with maximal urethral length preservation technique preserves penile length.

Penile shortening is a recognized but neglected side effect of prostate cancer treatment. In this study we explore the effect of maximal urethral length preservation (MULP) technique on penile length preservation after robot assisted laparoscopic prostatectomy (RALP). In an IRB approved study, we prospectively evaluated the stretched flaccid penile length (SFPL) pre and post RALP in subjects with a diagnosis of prostate cancer. The multiparametric MRI (MP-MRI) was utilized for surgical planning if available preoperatively. Repeated measures t-test, linear regression and 2-way ANOVA analyses were performed. A total of 35 subjects underwent RALP. Mean age was 65.8 yr (SD: 5.9), preoperative SFPL was 15.57 cm (SD: 1.66) and postoperative SFPL was 15.41 cm (SD: 1.61) p = 0.68. No change in the postoperative SFPL was recorded among 27 subjects (77.1%) while 5 subjects (14.3%) had 0.5 cm shortening, and 3 subjects (8.6%) had 1 cm shortening. Pathologic stage, preoperative MP-MRI and body mass index (BMI) were significant predictors of postoperative SFPL on linear regression analysis, p = 0.001. Among 26 subjects with pathologic stage 2 disease, no statistical difference was seen in repeated measures t-test between pre and postoperative SFPL, 15.36 vs 15.3 cm, p = 0.08. All subjects were continent by 6 months postoperatively, with no complications. We demonstrate that incorporating MULP technique and preoperative MP-MRI preserves SFPL in subjects undergoing a RALP.

Development of a predictive model for recurrence-free survival in pTa low-grade bladder cancer.

BACKGROUND: Data on Ta low-grade (LG) non-muscle invasive bladder cancer (NMIBC) have shown that follow-up cystoscopies are normal in 82% and 67% of patients with single and multiple tumors, respectively. OBJECTIVE: To develop a predictive model associated with recurrence-free survival (RFS) at 6, 12, 18 and 24 months in TaLG cases that consider the patients' risk aversion. MATERIALS AND METHODS: Data from a prospectively maintained database of 202 newly diagnosed TaLG NMIBC patients treated at Scandinavian institutions were used for the analysis. To identify risk groups associated with recurrence, we performed a classification tree analysis. Association between risk groups and RFS was evaluated by Kaplan Meier analysis. A Cox proportional hazard model selected significant risk factors associated with RFS using the variables defining the risk groups. The reported C index for the Cox model was 0.7. The model was internally validated and calibrated using 1000 bootstrapped samples. A nomogram to estimate RFS at 6, 12, 18, and 24 months was generated. The performance of our model was compared to EUA/AUA stratification using a decision curve analysis (DCA). RESULTS: The tree classification found that tumor number, tumor size and age were the most relevant variables associated with recurrence. The patients with the worst RFS were those with multifocal or single, ≥ 4cm tumors. All the relevant variables identified by the classification tree were significantly associated with RFS in the Cox proportional hazard model. DCA analysis showed that our model outperformed EUA/AUA stratification and the treat all/none approaches. CONCLUSION: We developed a predictive model to identify TaLG patients that benefit from less frequent follow-up cystoscopy schedule based on the estimated RFS and personal recurrence risk aversion.

Operative and oncological outcomes of salvage robotic radical and partial nephrectomy: a multicenter experience.

We aim to describe the perioperative and oncological outcomes for salvage robotic partial nephrectomy (sRPN) and salvage robotic radical nephrectomy (sRRN). Using a prospectively maintained multi-institutional database, we compared baseline clinical characteristics and perioperative and postoperative outcomes, including pathological stage, tumor histology, operative time, ischemia time, estimated blood loss (EBL), length of stay (LOS), postoperative complication rate, recurrence rate, and mortality. We identified a total of 58 patients who had undergone robotic salvage surgery for a recurrent renal mass, of which 22 (38%) had sRRN and 36 (62%) had sRPN. Ischemia time for sRPN was 14 min. The median EBL was 100 mL in both groups (p = 0.581). One intraoperative complication occurred during sRRN, while three occurred during sRPN cases (p = 1.000). The median LOS was 2 days for sRRN and 1 day for sRPN (p = 0.039). Postoperatively, one major complication occurred after sRRN and two after sRPN (p = 1.000). The recurrence reported after sRRN was 5% and 3% after sRPN. Among the patients who underwent sRRN, the two most prevalent stages were pT1a (27%) and pT3a (27%). Similarly, the two most prevalent stages in sRPN patients were pT1a (69%) and pT3a (6%). sRRN and sRPN have similar operative and perioperative outcomes. sRPN is a safe and feasible procedure when performed by experienced surgeons. Future studies on large cohorts are essential to better characterize the importance and benefit of salvage partial nephrectomies.

Factors that influence preference for male or female urologist among underserved patients in New York City.

Objective: To examine the prevalence of patient preference for male or female urologic provider and explore which patient characteristics influence this preference. Materials and Methods: After obtaining hospital Institutional Review Board approval, a 14-question survey in English and Spanish was administered across four general urology clinic sites in a single hospital system in New York City. The survey asked demographic questions and preference for a male or a female urologist. The survey included questions pertaining to the nature of the clinic visit and subsequent provider preference as well. Statistics were performed using Stata 16 (StataCorp, College Station, TX). Results: A total of 540 patients completed the 14-question survey. The vast majority of survey respondents identified as male (90%). The largest proportion demographic groups were those aged 41-60 (47%), Hispanic or Latino (43%), Catholic (47%), unemployed (40%) and those with a high school level of education (34%). Most patients (60%) did not have a preference for a specific gender provider, whereas 37% preferred a male provider, and 3% preferred a female provider. On univariate analysis, patient age 25-40, less than high school education level and lack of employment were significant predictors of provider gender preference (p < 0.05), with most patients indicating a male provider preference. On multivariate analysis of gender, age, education level and employment status, gender and education level were not significant predictors of preference, whereas age 25-40 and being unemployed were significant predictors (p < 0.05). Conclusion: Patient gender, race and religion do not appear to influence their preference to be seen by a male or a female urologist in the clinic setting. However, patient age, unemployment and potentially educational attainment were significantly associated with a provider gender preference.
