Healthcare system contact following ureteroscopy: does discharge instruction readability matter?

INTRODUCTION: We aimed to assess the impact of discharge instruction (DCI) readability on 30-day postoperative contact with the healthcare system. MATERIALS AND METHODS: Utilizing a multidisciplinary team, DCI were modified for patients undergoing cystoscopy, retrograde pyelogram, ureteroscopy, laser lithotripsy, and stent placement (CRULLS) from a 13th grade to a 7th grade reading level. We retrospectively reviewed 100 patients including 50 consecutive patients with original DCI (oDCI) and 50 consecutive patients with improved readability DCI (irDCI). Clinical and demographic data collected including healthcare system contact (communications [phone or electronic message], emergency department [ED], and unplanned clinic visits) within 30 days of surgery. Uni/multivariate logistic regression analyses used to identify factors, including DCI-type, associated with increased healthcare system contact. Findings reported as odds ratios with 95% confidence intervals and p values (< 0.05 significant). RESULTS: There were 105 contacts to the healthcare system within 30 days of surgery: 78 communications, 14 ED visits and 13 clinic visits. There were no significant differences between cohorts in the proportion of patients with communications (p = 0.16), ED visits (p =1.0) or clinic visits (p = 0.37). On multivariable analysis, older age and psychiatric diagnosis were associated with significantly increased odds of overall healthcare contact (p = 0.03 and p = 0.04) and communications (p = 0.02 and p = 0.03). Prior psychiatric diagnosis was also associated with significantly increased odds of unplanned clinic visits (p = 0.003). Overall, irDCI were not significantly associated with the endpoints of interest. CONCLUSIONS: Increasing age and prior psychiatric diagnosis, but not irDCI, were significantly associated with an increased rate of healthcare system contact following CRULLS.

A novel upper tract ureteroscopic biopsy technique: the "form tackle".

INTRODUCTION AND OBJECTIVE: Upper tract urothelial carcinoma (UTUC) represents 5% of all urothelial malignancies (1-3). Accurate pathologic diagnosis is key and may direct treatment decisions. Current ureteroscopic biopsy techniques include cold-cup, backloaded cold-cup and stone basket (4-6). The study objective was to compare a standard cold-cup biopsy technique to a novel cold-cup biopsy technique and evaluate histopathologic results. MATERIALS AND METHODS: We developed a novel UTUC biopsy technique termed the "form tackle" biopsy. Ureteroscope is passed into ureter/renal collecting system. Cold-cup forceps are opened and pressed into the lesion base (to engage the urothelial wall/submucosal tissue) then closed. Ureteroscope/forceps are advanced forward 3-10mm and then extracted from the patient. We compared standard versus novel upper tract biopsy techniques in a series of patients with lesions ≥1cm. In each procedure, two standard and two novel biopsies were obtained from the same lesion. The primary study aim was diagnosis of malignancy. IRB approved: 21-006907. RESULTS: Fourteen procedures performed on 12 patients between June 2020 and March 2021. Twenty-eight specimens sent (14 standard, 14 novel) (Two biopsies per specimen). Ten procedures with concordant pathology. In 4 procedures the novel biopsy technique resulted in a diagnosis of UTUC (2 high-grade, 2 low-grade) in the setting of a benign standard biopsy. Significant difference in pathologic diagnoses was detected between standard and novel upper tract biopsy techniques (p=0.008). CONCLUSIONS: The "form tackle" upper tract ureteroscopic biopsy technique provides higher tissue yield which may increase diagnostic accuracy. Further study on additional patients required. Early results are encouraging.

Continuing Collagenase Clostridium Histolyticum Injections Among Initial Nonresponders Results in Significant Curvature Improvements in the Majority of Peyronie's Disease Men.

BACKGROUND: It is currently unclear if men with Peyronie's Disease (PD) who achieve minimal benefits with the first 2 series of Collagenase Clostridium Histolyticum (CCH) injections should continue with additional injections. AIM: To analyze curvature improvements from the final two series of CCH injections based on amount of improvement during the first 2 series. METHODS: A prospective registry was analyzed of all men undergoing CCH injections for PD at a single institution. Men were included if they had completed a full 4 series (8 injections) of CCH and had baseline, interval (after 2 series), and/or final (after 4 series) curvature assessments available. Men were stratified into cohorts using baseline-to-interval assessments of ≤10° (or ≤20%) and >10° (or >20%), and improvements were compared using interval-to-final assessments. OUTCOMES: The primary outcome was interval-to-final curvature improvements stratified by ≤10°/>10° or ≤20%/>20% improvements achieved during the baseline-to-interval period. Secondary outcomes included analyses of demographic and pathophysiologic variables to determine associations with significant improvements during the final 2 CCH series. RESULTS: A total of 296 PD men were identified as receiving at least one CCH injection, of whom 175 had baseline-to-interval, 84 interval-to-final, and 115 with baseline-to-final measurements. Mean age was 56.6, PD duration 28.6 months, baseline curvature 63.4°, hourglass deformity 36.2%, and calcification 20%. Mean overall curve improvement was -21.5° (33.1%). Among men who experienced ≤20% improvements after 2 series, the mean subsequent curvature change was -24.6% during the final two series (vs +4.3% of those with >20% initial improvement, P< .001), and they were 2.7x more likely to experience >20% subsequent curve improvements. Thirty-one percent of those who achieved >10° during the first 2 series experienced benefits during the final 2 series compared to 70% of men who had ≤10° improvement initially. No demographic or pathophysiological variables predicted likelihood for improvements during the final 2 series of injections. CLINICAL IMPLICATIONS: Men who fail to achieve significant benefits with 2 series of CCH injections may benefit from completing the final 2 series. STRENGTHS AND LIMITATIONS: Strengths including a relatively large, prospective series. Limitations include a single center, nonrandomization, nonblinded assessments, and restriction to men who completed eight injections. CONCLUSIONS: In the current series, approximately 2/3 of men who fail to achieve >10° or 20% curve improvements with an initial 2 series of CCH injections achieved >10° or 20% improvements with the subsequent 2 series.

Adding carboplatin to chemotherapy regimens for metastatic castrate-resistant prostate cancer in postsecond generation hormone therapy setting: Impact on treatment response and survival outcomes.

BACKGROUND: The clinical course in metastatic castrate-resistant prostate cancer (mCRPC) can be complicated when patients have disease progression after prior treatment with second generation hormone therapy (second HT), such as enzalutamide or abiraterone. Currently, limited data exist regarding the optimal choice of chemotherapy for mCRPC after failing second generation hormone therapy. We sought to evaluate three common chemotherapy regimens in this setting. METHODS: We retrospectively identified 150 mCRPC patients with disease progression on enzalutamide or abiraterone. Of these 150 patients, 92 patients were chemo-naïve while 58 patients had previously received docetaxel chemotherapy before being started on second HT. After failing second HT, 90 patients were assigned for docetaxel-alone (group A), 33 patients received carboplatin plus docetaxel (group B), while 27 patients received cabazitaxel-alone (Group C). A favorable response was defined by more than or equal to 50% reduction in prostate-specific antigen from the baseline level after a complete course of chemotherapy. Survival outcomes were assessed for 30-month overall survival. RESULTS: Patients in group (B) were 2.6 times as likely to have a favorable response compared to patients in group (A) (OR = 2.625, 95%CI: 1.15-5.99) and almost three times compared to patients in group (C) (OR = 2.975, 95%CI: 1.04-8.54) (P = .0442). 30-month overall survival was 70.7%, 38.9% and 30.3% for group (B), (A), and (C), respectively (P = .008). We report a Hazard Ratio of 3.1 (95% CI, 1.31-7.35; P = .0037) between patients in group (A) versus those in group (B) and a Hazard Ratio of 4.18 (95% CI, 1.58-11.06; P = .0037) between patients in group (C) compared to those in group (B) CONCLUSION: This data demonstrates improved response and overall survival in treatment-refractory mCRPC with a chemotherapy regimen of docetaxel plus carboplatin when compared to docetaxel alone or cabazitaxel alone. Further investigations are required.

Outcomes of RestoreX Penile Traction Therapy in Men With Peyronie's Disease: Results From Open Label and Follow-up Phases.

BACKGROUND: A randomized, controlled clinical trial evaluating the efficacy of RestoreX traction therapy in men with Peyronie's disease (PD) has been completed, with the 3-month results previously reported. The present study presents outcomes from the open-label and follow-up phases of the original trial. AIM: To report 6-month (open-label phase) and 9-month (follow-up phase) outcomes from a randomized, controlled trial (NCT03389854). METHODS: A randomized controlled trial was performed from 2017 to 2019 in 110 all-comer men with PD. Men were randomized 3:1 to RestoreX (PTT) or no therapy (control) for 3 months, followed by 3-month open-label and follow-up phases. Key outcomes included adverse events (AEs), changes in penile curvature and length, erectile function, and standardized and nonstandardized assessments of PD. OUTCOMES: The primary outcomes are safety, penile length, penile curvature, Peyronie's Disease Questionnaire, International Index of Erectile Function, and satisfaction. RESULTS: 6-month (n = 64) and 9-month (n = 63) outcomes were reported, with a mean duration of PTT use of 31.1 minutes. No significant AEs were reported, with temporary erythema and discomfort being most common and resolving within minutes. On intent-to-treat analysis, control-to-PTT men experienced significant length (1.7-2.0 cm) and curvature improvements (18-20%). PTT-to-PTT men also achieved additional length (0.6-0.8 cm) without further curvature improvements. An as-treated analysis of PTT use ≥15 minute/day demonstrated 2.0- to 2.3-cm length gains (largest of any PTT to date) and 18-21% curve improvement. All sexual function domains of the International Index of Erectile Function and Peyronie's Disease Questionnaire were significantly improved (except orgasmic domain). 95% of men treated for 6 months experienced length gains (mean 2.0-2.2 cm), and 61% had curve improvements (16.8-21.4° [32.8-35.8%]). RestoreX was preferred 3-4:1 over all other PD treatments, and 100% preferred it over other PTT devices. CLINICAL IMPLICATIONS: Use of RestoreX 30 minutes daily results in significant length and curve improvements in PD men without significant AEs. STRENGTHS & LIMITATIONS: Strengths include largest randomized study of PTT, blinded assessments, and inclusion of all-comers with few restrictions; limitations include sample size that precludes comparisons between treatment cohorts and lack of long-duration (>3-9 hours) treatment arm. CONCLUSION: PTT with RestoreX results in significant improvements in length, curve, and subjective and objective measures of sexual function without significant AEs. RestoreX PTT represents a safe, conservative, low-cost option for managing men with PD. Joseph J, Ziegelmann M, Alom M, et al.

Prevalence and Predictors of Climacturia and Associated Patient/Partner Bother in Patients With History of Definitive Therapy for Prostate Cancer.

BACKGROUND: Climacturia is an under-reported complication of definitive therapy for prostate cancer (PCa) - that is, radical prostatectomy (RP) and/or radiation therapy (RT). AIM: We sought to identify the prevalence and predictors of climacturia and associated patient/partner bother in patients with and without prior PCa treatment. METHODS: We analyzed a database of patients who presented to our Men's Health clinic and filled out a questionnaire related to sexual function and pertinent medical histories. The prevalence of climacturia and associated patient/partner bother in patients with/without prior RP/RT was calculated. Univariable and multivariable logistic regressions were performed to identify predictors associated with climacturia and patient/partner bother. OUTCOMES: The primary outcomes were the prevalence and predictors of climacturia and associated patient/partner bother in patients with/without history of definitive PCa treatment. RESULTS: Among 1,117 patients able to achieve orgasm, 192 patients (17%) had prior history of definitive therapy for PCa (RP alone = 139 [72%]; RT alone = 22 [11%]; RP + RT = 31 [16%]). Climacturia was reported by 39%, 14%, 52%, and 2.4% of patients with history of RP alone, RT alone, RP + RT, and neither RP nor RT, respectively (P < .05 between all groups). 33 to 45 percent of patients with climacturia noted significant patient/partner bother. Factors significantly associated with climacturia were prior RP, prior RT, history of other prostate surgery, and erectile dysfunction, although erectile dysfunction was not significant on multivariable analysis. Significant reduction in climacturia prevalence was noted for patients who were ≥1 year out from RP, compared with patients who were <1 year out. Among patients with prior RP/RT, stress urinary incontinence was associated with increased risk of climacturia, whereas diabetes was associated with decreased risk. No factors were associated with patient/partner bother. Among patients with prior RP, nerve-sparing technique did not predict presence of climacturia but was associated with reduced patient/partner bother. CLINICAL TRANSLATION: Given significant prevalence of climacturia and associated patient/partner bother, patients should be counseled on the risk of climacturia before undergoing RP/RT. STRENGTHS AND LIMITATIONS: Strengths include the large study population and the focus on both RP and RT. Limitations include the facts that this is a single-institution study that primarily relies on patients' subjective reporting and that the study population may not represent the general population. CONCLUSIONS: Climacturia affects a significant proportion of patients with history of RP/RT for PCa, and many patients and their partners find this bothersome. Jimbo M, Alom M, Pfeifer ZD, et al.

Outcomes of a Novel Penile Traction Device in Men with Peyronie's Disease: A Randomized, Single-Blind, Controlled Trial.

PURPOSE: Current penile traction therapy devices have significant limitations, including the need to use them for 3 to 8 hours per day. Given these issues, the novel RestoreX® penile traction therapy device was developed in cooperation with Mayo Clinic. MATERIALS AND METHODS: We performed a randomized, controlled, single-blind, intent to treat trial (ClinicalTrials.gov NCT03389854) in men with Peyronie's disease who were assigned to the penile traction therapy device for 30 to 90 minutes per day or to no therapy for 3 months. Study inclusion criteria were curvature 30 degrees or greater with no study exclusions due to complex curvature, hourglass deformity, prior Peyronie's disease therapy or surgery, or calcification. The primary outcome was safety and secondary outcomes were penile length and curvature, and questionnaire responses. RESULTS: A total of 110 men were randomized 3:1 to the penile traction therapy group or the control group. The cohorts were well matched with a mean age of 58.4 years, a 49.7-month Peyronie's disease history and 59.3 degree curvature. Overall penile traction therapy was well tolerated with only transient and mild adverse events reported. At 3 months men undergoing penile traction therapy demonstrated significant improvements over controls in penile length (1.5 vs 0 cm, p <0.001), curvature (-11.7 vs 1.3 degrees, p <0.01) and erectile function (4.3 vs -0.7, p = 0.01) according to the International Index of Erectile Function-Erectile Function among men with erectile dysfunction. Overall 77% of the men on penile traction therapy experienced improved curvature (mean -17.2 degrees in 28.2% of responders) while 94% achieved increased length (1.6 cm in 10.9%). Counter bending and the white line indicator improved efficacy, validating key device innovations. Of men who had previously used other penile traction therapy devices 100% preferred the RestoreX device. CONCLUSIONS: Penile traction therapy with the RestoreX device for 30 to 90 minutes per day was safe, and resulted in significant and clinically meaningful improvements in penile curvature and length in men with Peyronie's disease, and in erectile function in men with erectile dysfunction and Peyronie's disease with no significant adverse events. To our knowledge these data represent the only reported improvements for any device used less than 3 to 8 hours per day.

Emerging Complications Following Alternative Reservoir Placement during Inflatable Penile Prosthesis Placement: A 5-Year Multi-Institutional Experience.

PURPOSE: Alternative or ectopic reservoir placement has recently gained popularity among prosthetic surgeons to avoid injury to pelvic structures during inflatable penile prosthesis implantation. However, the true incidence of complications associated with these new techniques remains under studied. We performed a 5-year multicenter, retrospective study with the aim of evaluating complications related to alternative reservoir placement. MATERIALS AND METHODS: We retrospectively reviewed the database of inflatable penile prosthesis surgery at 3 institutions from February 2011 to December 2016. The mechanism of failure and complications related to reservoir placement were analyzed. RESULTS: A total of 974 inflatable penile prostheses were placed in the 5-year period by 3 surgeons, including 612 surgeries with alternative reservoir placement. Mean followup to the emergence of reservoir related complications was 20.4 months. There was no significant difference in complication rates between primary and revision cases (p = 0.72). A total of 12 cases (2.0%) required revision for reservoir related complications in the alternative reservoir placement group vs 1.3% in the space of Retzius group (p = 0.44). The most common complication in the alternative reservoir placement group was reservoir leakage, which developed in 5 patients. Three cases required revision due to abdominal muscular pain. Torsion in the tubing of 3 Conceal™ reservoirs was found which caused blockage of fluid transportation. One reservoir was incidentally found to be intraperitoneal on unrelated imaging. CONCLUSIONS: Alternative reservoir placement is a safe and mechanically reliable approach, including in men with prior pelvic surgery. However, there are associated risks, including reservoir leakage, tubing torsion, muscle discomfort and unintended reservoir malposition which may require surgical revision.

Implementation of multiparametric magnetic resonance imaging technology for evaluation of patients with suspicion for prostate cancer in the clinical practice setting.

OBJECTIVES: To investigate the impact of implementing magnetic resonance imaging (MRI) and ultrasonography fusion technology on biopsy and prostate cancer (PCa) detection rates in men presenting with clinical suspicion for PCa in the clinical practice setting. PATIENTS AND METHODS: We performed a review of 1 808 consecutive men referred for elevated prostate-specific antigen (PSA) level between 2011 and 2014. The study population was divided into two groups based on whether MRI was used as a risk stratification tool. Univariable and multivariable analyses of biopsy rates and overall and clinically significant PCa detection rates between groups were performed. RESULTS: The MRI and PSA-only groups consisted of 1 020 and 788 patients, respectively. A total of 465 patients (45.6%) in the MRI group and 442 (56.1%) in the PSA-only group underwent biopsy, corresponding to an 18.7% decrease in the proportion of patients receiving biopsy in the MRI group (P < 0.001). Overall PCa (56.8% vs 40.7%; P < 0.001) and clinically significant PCa detection (47.3% vs 31.0%; P < 0.001) was significantly higher in the MRI vs the PSA-only group. In logistic regression analyses, the odds of overall PCa detection (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.29-2.35; P < 0.001) and clinically significant PCa detection (OR 2.04, 95% CI 1.48-2.80; P < 0.001) were higher in the MRI than in the PSA-only group after adjusting for clinically relevant PCa variables. CONCLUSION: Among men presenting with clinical suspicion for PCa, addition of MRI increases detection of clinically significant cancers while reducing prostate biopsy rates when implemented in a clinical practice setting.

Efficacy of Combined Collagenase Clostridium histolyticum and RestoreX Penile Traction Therapy in Men with Peyronie's Disease.

BACKGROUND: Previous studies of penile traction therapy (PTT) devices have demonstrated limited/no efficacy when combined with intralesional therapies for Peyronie's disease (PD). Recently, randomized data have demonstrated the efficacy of a novel PTT device, RestoreX, developed in cooperation with the Mayo Clinic, in men with PD. AIM: To assess the safety and efficacy of treatment with the RestoreX device plus collagenase Clostridium histolyticum (CCH) compared with CCH alone and CCH with other PTT devices. METHODS: A prospective registry has been maintained of all men undergoing CCH injections for PD between March 2014 and January 2019. Assessments were performed at baseline, during each series, and after completion of treatment. Those completing therapy (8 injections or sooner if satisfied) were categorized into group 1 (CCH alone), group 2 (CCH plus any PTT device other than RestoreX), or group 3 (CCH plus RestoreX). OUTCOMES: Changes in penile length, curvature, and subjective perception and the occurrence of adverse events. RESULTS: Of 287 men with data on PTT use, 113 had completed therapy with all objective data available and compose the current cohort. Baseline demographic and pathophysiological variables were similar among the 3 groups except penile length and previous PD medications. Following treatment, group 3 demonstrated significantly greater improvements in curvature (mean, 20.3°/31% for group 1, 19.2°/30% for group 2, and 33.8°/49% for group 3), length (-0.7 cm/-4%, -0.4 cm/-2%, and +1.9 cm/+17%, respectively), and subjectively estimated curvature improvement (44%, 32%, and 63% respectively), despite shorter daily PTT use (0.9 vs 1.9 hours/day). Group 3 was more likely than the other groups to experience ≥20°, ≥20%, and ≥50% curvature improvements, ≥1 cm length gain, and ≥20% length improvement. All results were statistically significant for group 3 versus groups 1 and 2, but not between groups 1 and 2, even after controlling for baseline features and isolating a subset of ≥3 hours/day PTT use (group 2). Group 3 was 6.9 times more likely to achieve ≥20° curvature improvement, and 3.5 times more likely to achieve ≥50% curvature improvement, and 10.7 times more likely to experience ≥20% length improvement. Adverse events were similar among the 3 groups. CLINICAL IMPLICATIONS: Use of the RestoreX device enhances mean curvature outcomes by 71% and increases penile length in men with PD receiving CCH therapy. STRENGTHS & LIMITATIONS: Study strengths include a prospective registry, consistent assessments, the largest single-site series with complete posttreatment outcomes reported to date, the largest PTT series reported to date, and a true-to-life clinical design. Limitations include the nonrandomized methodology and single-site setting. CONCLUSION: The combination of RestoreX and CCH is associated with significantly greater curvature and length improvements compared with CCH alone or CCH with other PTT devices.

The Temporal Association of Robotic Surgical Diffusion with Overtreatment of the Small Renal Mass.

PURPOSE: We evaluated contemporary practice patterns in the management of small renal masses. MATERIALS AND METHODS: We identified 52,804 patients in the NCDB (National Cancer Database) who were diagnosed with a small renal mass (4 cm or less) between 2010 and 2014. Utilization trends of active surveillance, ablation and robotic, laparoscopic and open surgical techniques were compared among all comers, elderly patients 75 years old or older and individuals with competing health risks, defined as a Charlson index of 2 or greater. Multivariable logistic regression models were used to assess factors associated with robotic renal surgery and active surveillance. RESULTS: Surgery remained the primary treatment modality across all years studied, performed in 75.0% and 74.2% of cases in 2010 and 2014, respectively. Although increases in active surveillance from 4.8% in 2010 to 6.0% in 2014 (p <0.001) and robotic renal surgery (22.1% in 2010 to 39.7% in 2014, p <0.001) were observed, the increase in the proportion of small renal masses treated with robotic partial and radical nephrectomy was greater than that of active surveillance (82.0% and 63.0%, respectively, vs 25.0%). Subgroup analyses in individuals 75 years old or older, or with a Charlson index of 2 or greater likewise revealed preferential increases in robotic surgery vs active surveillance. On multivariable analysis later year of diagnosis was associated with increased performance of robotic renal surgery compared to active surveillance (2014 vs 2010 OR 1.44, 95% CI 1.20-1.72, p <0.001) and nonrobotic procedural interventions (2014 vs 2010 OR 2.59, 95% CI 2.30-2.93, p <0.001). CONCLUSIONS: Robotic surgical extirpation has outpaced the adoption of active surveillance of small renal masses. This raises concern that the diffusion of robotic technology propagates overtreatment, particularly among elderly and comorbid individuals.

Modified Glanulopexy Technique for Supersonic Transporter Deformity and Glanular Hypermobility in Men With Penile Prostheses.

BACKGROUND: Glanular hypermobility (GH) or supersonic transporter (SST) deformity are occasionally encountered during penile prosthesis (PP) implantation, yet management strategies are underreported with minimal data available on surgical outcomes. AIM: To describe a modified technique for glanulopexy to correct GH/SST in men undergoing PP placement and assess outcomes associated with this technique. METHODS: Glanulopexy was performed in men with GH/SST identified at the time of or following PP placement. A modification to previously described techniques was performed, whereby a suture is passed into the glans and secured to the tissue overlying the corpora through small incisions on the lateral aspects of the distal penile shaft. OUTCOMES: Correction of the anatomic deformity (GH/SST), device infection, and changes in penile sensation were evaluated during post-operative follow-up. RESULTS: From 2014-2017, a total of 12 patients underwent modified glanulopexy for GH/SST. Nine (75%) were performed at the time of PP, while the remaining 3 were performed in a delayed fashion. At a median follow-up of 12 months (range 1-33 months), all patients with the device in situ demonstrated appropriate glanular positioning, and no patients reported changes in penile sensation. A single patient required device removal secondary to infection. CLINICAL TRANSLATION: Glanulopexy with permanent suture successfully corrects severe GH or SST in men with inflatable PP without reduced penile sensation. CONCLUSIONS: Strengths of the current study include the description of a simple, safe, and reproducible technique for GH/SST that adds minimal operative time and can be performed under local anesthesia when necessary. To our knowledge, this represents one of the largest reported series of glanulopexy outcomes reported in the literature. Limitations include that this is a single-surgeon series, there is limited follow-up, and lack of a comparison group. Further study with external validation is warranted to establish the optimal role for the procedure. Ziegelmann MJ, Alom M, Bole R, et al. Modified Glanulopexy Technique for Supersonic Transporter Deformity and Glanular Hypermobility in Men With Penile Prostheses. J Sex Med 2018;15:914-919.

Clinical Factors Negatively Impacting Sexual Relationships in Men With Peyronie's Disease.

Here, we sought to identify clinical factors associated with a negative impact on the relationships patients with Peyronie's disease (PD) have with their partners. During initial consultation, a detailed sexual questionnaire was administered, which included a question on whether or not PD negatively impacted the current sexual relationship. More than half (146/242; 60.3%) of patients reported that PD negatively impacted their sexual relationship. On multivariate analysis, penile shortening, partner pain with intercourse, and shorter relationship duration were associated with a negative relationship effect. We did not identify significant differences in negative relationship effects based on objective physical examination findings including penile curvature, calcification, hourglass deformity, or penile length.

Partial Nephrectomy is Associated with Higher Risk of Relapse Compared with Radical Nephrectomy for Clinical Stage T1 Renal Cell Carcinoma Pathologically Up Staged to T3a.

PURPOSE: We studied recurrence-free survival after partial vs radical nephrectomy for clinical stage T1 renal cell carcinoma in all patients and in those up staged to pathological stage T3a. MATERIALS AND METHODS: We retrospectively reviewed the records of 1,250 patients who underwent partial or radical nephrectomy for clinically localized T1 renal cell carcinoma between 2006 and 2014. Recurrence-free survival was estimated using the Kaplan-Meier method and evaluated as a function of nephrectomy type with the log rank test and Cox models, adjusting for clinical, radiological and pathological characteristics. RESULTS: A total of 86 recurrences (7%) were observed during a median followup of 37 months. No difference in recurrence-free survival between partial and radical nephrectomy was found among all clinical stage T1 renal cell carcinomas. T3a up staging was noted in 140 patients (11%) and recurrent disease was observed in 44 (31.4%) during a median followup of 38 months. Among up staged T3a cases partial nephrectomy was associated with shorter recurrence-free survival compared to radical nephrectomy on univariable analysis (recurrence HR 2.04, 95% CI 1.12-3.68, p = 0.019) and multivariable analysis (recurrence HR 5.39, 95% CI 1.94-14.9, p = 0.001). CONCLUSIONS: In a subgroup of patients clinically staged T1 renal cell carcinoma will be pathologically up staged to T3a. Among these patients those who undergo partial nephrectomy appear to have inferior recurrence-free survival relative to those who undergo radical nephrectomy.

Active surveillance for incidental renal mass in the octogenarian.

OBJECTIVE: To evaluate the oncologic outcomes among a large cohort of octogenarian patients placed on active surveillance for a localized renal mass. METHODS: We retrospectively reviewed patients ≥80 years of age presenting for asymptomatic, incidentally detected clinically localized stage T1 renal mass between 2006 and 2013 who were followed by active surveillance (AS). The primary endpoint was development of metastatic renal cell carcinoma. Secondary outcomes included intervention-free survival, cancer-specific survival, and overall survival. RESULTS: Eighty-nine octogenarians (median age = 83.4 years) were placed on AS for a median 29.9 months. Median Charlson Comorbidity Index and Katz Index of Independence in Activities of Daily Living scores were 2 and 5, respectively. For all comers, median initial tumor size was 2.4 cm with median growth rate of 0.20 cm/year. Eight (9.0%) patients failed AS due to delayed intervention and three (1.1%) due to systemic progression after median follow-up of 27.8 and 39.9 months, respectively. Two (2.2%) patients in the delayed intervention cohort developed metastasis after treatment. Tumor growth rate was significantly higher among those undergoing intervention versus no intervention (0.60 vs. 0.15 cm/year, P = 0.05) and among patients with systemic progression versus no metastasis (1.28 vs. 0.18 cm/year, P = 0.001). Five-year intervention-free, metastasis-free, cancer-specific, and overall survivals were 90.6, 95.6, 95.6, and 85.7%, respectively. CONCLUSION: AS represents an effective management strategy in octogenarians given low overall risk of metastasis. Tumor growth kinetics may identify patients at risk of systemic progression in whom treatment should be considered.

Positive Surgical Margins Increase Risk of Recurrence after Partial Nephrectomy for High Risk Renal Tumors.

PURPOSE: The clinical significance of a positive surgical margin after partial nephrectomy remains controversial. The association between positive margin and risk of disease recurrence in patients with clinically localized renal neoplasms undergoing partial nephrectomy was evaluated. MATERIALS AND METHODS: A retrospective multi-institutional review of 1,240 patients undergoing partial nephrectomy for clinically localized renal cell carcinoma between 2006 and 2013 was performed. Recurrence-free survival was estimated using the Kaplan-Meier method and evaluated as a function of positive surgical margin with the log rank test and Cox models adjusting for tumor size, grade, histology, pathological stage, focality and laterality. The relationship between positive margin and risk of relapse was evaluated independently for pathological high risk (pT2-3a or Fuhrman grades III-IV) and low risk (pT1 and Fuhrman grades I-II) groups. RESULTS: A positive surgical margin was encountered in 97 (7.8%) patients. Recurrence developed in 69 (5.6%) patients during a median followup of 33 months, including 37 (10.3%) with high risk disease (eg pT2-pT3a or Fuhrman grade III-IV). A positive margin was associated with an increased risk of relapse on multivariable analysis (HR 2.08, 95% CI 1.09-3.97, p=0.03) but not with site of recurrence. In a stratified analysis based on pathological features, a positive surgical margin was significantly associated with a higher risk of recurrence in cases considered high risk (HR 7.48, 95% CI 2.75-20.34, p <0.001) but not low risk (HR 0.62, 95% CI 0.08-4.75, p=0.647). CONCLUSIONS: Positive surgical margins after partial nephrectomy increase the risk of disease recurrence, primarily in patients with adverse pathological features.

To clamp or not to clamp? Long-term functional outcomes for elective off-clamp laparoscopic partial nephrectomy.

OBJECTIVE: To evaluate whether elective off-clamp laparoscopic partial nephrectomy (LPN) affords long-term renal functional benefit compared with the on-clamp approach. PATIENTS AND METHODS: This is a retrospective review of patients who underwent elective LPN between 2006 and 2011. Patients were followed longitudinally for up to 5 years. In all, 315 patients with radiographic evidence of a solitary renal mass and normal-appearing contralateral kidney underwent elective LPN; 209 were performed on-clamp vs 106 off-clamp. One patient who required conversion from LPN to open PN was excluded from the study. Additionally, four patients in the on-clamp cohort who underwent subsequent radical nephrectomy for local-regional recurrence were excluded from longitudinal functional evaluation after their procedure. The primary objective was to evaluate differences in postoperative estimated glomerular filtration rate (eGFR) between hilar clamping groups. Subgroup analyses were performed for patients with clamp times >30 min and those with baseline renal insufficiency (eGFR <60 mL/min/1.73m(2) ). Risk of developing worsened or new-onset renal insufficiency was also compared. RESULTS: The mean preoperative eGFR was similar between the on-clamp and off-clamp cohorts (80.7 vs 84.1 mL/min/1.73m(2) , P > 0.05). Univariable and multivariable analyses did not show significant differences in postoperative eGFR between both groups among all-comers, those with clamp times >30 min, and patients with baseline renal insufficiency. Risk of chronic kidney disease was not diminished by the off-clamp approach with up to 5 years of follow-up. CONCLUSIONS: Progressive recovery of renal function after hilar clamping in the elective setting eclipses short-term functional benefit achieved with off-clamp LPN by 6 months; there was no significant difference in eGFR or the percentage incidence of chronic kidney disease between the on-clamp and off-clamp cohorts with up to 5 years follow-up. As such, eliminating transient ischaemia during elective LPN does not confer clinical benefit.

The Discontinuation Rate With Collagenase Clostridium histolyticum for Peyronie's Disease in a High-volume Practice Is Unexpectedly High: Identifying Opportunities for Patient Care Improvement.

OBJECTIVE: To elucidate reasons for premature discontinuation of Collagenase Clostridium histolyticum (CCH) injections for the treatment of penile curvature associated with Peyronie's disease. METHODS: A database of men who underwent CCH injections at a single institution was queried to identify men who completed fewer than 8 injections. Chart review was conducted to identify reasons for treatment discontinuation. When this could not be identified, patients were contacted first via the online patient portal and next by phone. RESULTS: Of 406 patients who underwent CCH treatment, 133 did not complete 8 injections (32.8%). The most common reasons for discontinuation were satisfactory curve reduction (27%), unsatisfactory curve reduction (21%), bothersome side effect (15%), and pursuit of surgery (12%). Other less common reasons included other health concerns, pausing treatment due to the COVID-19 pandemic, high cost, transferring care elsewhere, and lack of awareness that more injections were indicated. CONCLUSION: We present the largest series of patients to date dedicated to evaluation of CCH discontinuation. We find that up to 1/3 of patients who begin CCH injections will not complete the full treatment course. Understanding the reasons for discontinuation can help providers better stratify patients for CCH treatment vs other modalities. In addition, as previous studies indicate curvature improvements are equally likely to be seen in the final four injections as the first four, our data points to the potential impact of improved patient education for individuals who discontinue due to unsatisfactory curve reduction.

The clinical significance of imperfection: is idiopathic corporal asymmetry related to curvature during penile prosthesis placement?

Patient satisfaction after inflatable penile prosthesis (IPP) has been linked to preexisting curvature; however the association with intraoperative asymmetric corporal measurements (ACM) has not been well described. We sought to identify incidence of ACM during IPP surgery, and relationship to penile curvature. A retrospective review of all patients undergoing primary IPP placement between 6/2019 and 6/2021 was performed. Logistic regression analysis was performed to identify factors associated with ACM and need for adjunct straightening techniques. A total of 273 patients underwent primary IPP. 27.8% had Peyronie's disease (PD) diagnosed preoperatively or detected intraoperatively. ACM was identified in 20.1% (55/273) patients. There was no significant difference in ACM in PD versus non-PD patients (p = 0.55). Most patients with ACM (78.2%, 43/55) underwent placement of asymmetric device. ACM did not predict need for invasive straightening maneuvers (p = 0.12). However ACM patients were significantly more likely to have mild residual curvature than those with symmetry (p < 0.0001). Our study is first to address management of idiopathic ACM and association with curvature, providing new insight into a common situation. While ACM was detected in 20%, it did not predict need for adjunct straightening techniques. Our findings may provide reassurance to urologists troubleshooting idiopathic ACM during corporal dilation during IPP surgery.
