RESUMEN

OBJECTIVE: To present 2 clitoroplasty techniques-the preputial skin and urethral flap-and describe our rationale for using each technique to construct the clitoro-urethral complex in gender-affirming vaginoplasty. METHODS: For uncircumcised patients or circumcised patients with greater than 2 cm of inner preputial skin and at least 8 cm of shaft skin proximal to the circumcision scar, we use the preputial skin clitoroplasty, a modification of the Ghent style clitoroplasty. The entire corona is used after medial glans and urethral mucosa is excised. The corona is brought together 1 cm from midline to create the visible ovoid clitoris; the remaining coronal tissue remains lateral to the clitoris for erogenous sensation as clitoral corpora. The clitoris is anchored to the proximal tunica, positioned at the level of the adductor longus tendon. The folded neurovascular bundle is fixed in the suprapubic area. The ventral urethral is spatulated and urethral flap approximated to the clitoris. Preputial skin is sutured proximally as tension allows. The clitoro-urethral complex is inset into an opening created in the penile skin flap. For patients with less skin, we use the urethral flap clitoroplasty. More corpus spongiosum is used, as the urethra creates the clitoral hood; this is described in the literature and attributed to Pierre Brassard. The clitoris is inset following a dorsal urethrotomy, with a small collar of preputial skin sewn to the spongiosum and urethral mucosa. The urethra is transected about 1 cm distally. The ventral urethra is then spatulated and the urethroplasty completed. RESULTS: We prefer the preputial skin flap technique for its' greater coronal tissue volume for erogenous sensation and better esthetics, in our opinion. Circumcised patients should have at least 2 cm of skin distal to the circumcision scar. To avoid using skin graft for the introitus-a risk for introital stenosis-shaft skin proximal to the circumcision line should be at least 8 cm. CONCLUSION: We present 2 technical options for clitoroplasty and construction of the clitoro-urethral complex in gender-affirming vaginoplasty.

RESUMEN

PURPOSE: This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD. METHODS: A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics. RESULTS: Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47). CONCLUSION: COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

RESUMEN

Background and Objective: Transgender and gender diverse (TGD) individuals may seek gender-affirming phalloplasty with specific functional goals, including erectile function sufficient for penetrative sexual intercourse. Individuals seeking penile prosthesis placement must accept the potential risks to their phallic anatomy. Methods: We review current practices at our center and narrative review of literature discussing techniques for penile prosthesis and testicular prosthesis placement after phalloplasty and scrotoplasty, as well as surgical outcomes, and quality of life outcomes where available. Key Content and Findings: Early discussion of a staged approach to phallic construction with a last step of implant placement is important during initial phalloplasty counseling. Pre-operative counseling at our multi-disciplinary center includes: discussion of surgical history, complications, goals and priorities; physical exam to evaluate phallic size and position, scrotal size, and other anatomic findings that may influence prosthesis selection; urinary evaluation, including uroflowmetry with post-void residual, and a cystoscopy with retrograde urethrogram if indicated based on symptoms or urinary studies, and discussion of surgical risks, benefits and alternatives. Although none of the commercially available penile prosthesis devices in the United States are designed for phalloplasty, modern inflatable and malleable prostheses are adapted for use in the post-phalloplasty setting. Due to the lack of native corpora cavernosa, highly variable phallic anatomy, and the need to adapt implants designed for natal penile anatomy, complication rates of prosthesis placement after phalloplasty remain high, with reported ranges of complications from 20% to 80%. Conclusions: Major complications requiring surgical revision are common relative to implant placement in natal penile anatomy, and include: infection requiring explantation, device extrusion, erosion, migration or malposition, inadequate rigidity, poor aesthetic result, pain, decrease or loss of erogenous and/or tactile sensation, device failure, injury to the urethra, and injury to the neurovascular supply of the penis with resultant partial or complete flap loss. This broad range of complication rates represents the variability with which results are reported and reflect a lack of clear reporting guidelines, significant variability in techniques, and need for more standardization. To optimize outcomes, it is important that surgeons have an in-depth understanding of phalloplasty anatomy and are equipped to manage potential complications in the short- and long-term.

RESUMEN

Transgender and non-binary (TGNB) individuals are seeking penile reconstruction in greater numbers; many pursue urethral lengthening surgery with a goal of voiding while standing. Changes in urinary function and urologic complications-i.e., urethrocutaneous fistulae and urinary stricture-are common. Familiarity with presenting symptoms and management strategies for urinary complaints after genital gender-affirming surgery (GGAS) can improve patient counseling and outcomes. We will describe current gender-affirming penile construction options with urethral lengthening and review associated urinary complications that present as urinary incontinence. The incidence and impact of lower urinary tract symptoms after metoidioplasty and phalloplasty are poorly characterized due to limited post-operative follow-up. Post-phalloplasty, urethrocutaneous fistula is the most common urethral complication, ranging in incidence from 15-70%. Assessment of concomitant urethral stricture is necessary. No standard technique exists for management of these fistula or strictures. Metoidioplasty studies report lower rates of stricture and fistula, 2% and 9% respectively. Other common voiding complaints include dribbling, urethral diverticula and vaginal remnants. History and physical exam in the post-GGAS evaluation require understanding of prior surgeries and attempted reconstructive efforts; adjuncts to physical exam include uroflowmetry, retrograde urethrography, voiding cysto-urethrogram, cystoscopy, and MRI. Following gender-affirming penile construction, TGNB patients may experience a host of urinary symptoms and complications that impact quality of life. Due to anatomic differences, symptoms require tailored evaluation which can be done by urologists in an affirming environment.

RESUMEN

INTRODUCTION: Wound related complications (WRC) are a significant source of morbidity in kidney transplant recipients, and may be mitigated by surgical approach. We hypothesize that the anterior rectus sheath approach (ARS) may decrease WRC and inpatient opiate use compared to the Gibson Approach (GA). METHODS: This double-blinded randomized controlled trial allocated kidney transplant recipients aged 18 or older, exclusive of other procedures, 1:1 to ARS or GA at a single hospital. The ARS involves a muscle-splitting paramedian approach to the iliopsoas fossa, compared to the muscle-cutting GA. Patients and data analysts were blinded to randomization. RESULTS: Seventy five patients were randomized to each group between August 27, 2019 and September 18, 2020 with a minimum 12 month follow-up. There was no difference in WRC between groups (p = .23). Nine (12%) and three patients (4%) experienced any WRC in the ARS and GA groups, respectively. Three and one Clavien IIIb complications occurred in the ARS and GA groups, respectively. In a multiple linear regression model, ARS was associated with decreased inpatient opioid use (ß = -58, 95% CI: -105 to -12, p = .016). CONCLUSIONS: The ARS did not provide a WRC benefit in kidney transplant recipients, but may be associated with decreased inpatient opioid use.

RESUMEN

OBJECTIVE: To describe the first known case of recurrent acute priapism after penile prosthesis implantation. MATERIALS AND METHODS: A 60-year-old gentleman with a history of recurrent ischemic priapism without hemoglobinopathy presented with refractory erectile dysfunction and underwent uncomplicated penile prosthesis placement. His course was complicated by early acute ischemic priapism confirmed via ultrasound. Due to his pain, attempts to relieve the priapism using ultrasound-guided phenylephrine injections were attempted but were unsuccessful. RESULTS: He subsequently underwent exploration with confirmation of distal ischemic priapism followed by brisk bright red blood from the proximal corpora upon device externalization. A perineal exploration was performed and the bilateral cavernosal arteries were suture ligated with immediate relief. The device was reimplanted and the patient recovered uneventfully. CONCLUSION: We report the first known case of ischemic priapism following inflatable penile prosthesis implantation. The details of this case challenge the dogma that priapism is a binary event and instead supports an imbalance between unopposed cavernosal artery inflow possibly due to vascular calcifications and compromised venous outflow due to the presence of the device. Prosthetic urologists should be aware of this rare phenomenon and consider all available approaches on an individualized case-by-case basis.

RESUMEN

Recent population-based studies suggest that the incidence of advanced and metastatic prostate cancer may be increasing. Concurrently with this apparent stage migration toward advanced disease, several major developments have occurred in the treatment paradigm for men with advanced prostate cancer. These include the US Food and Drug Administration approval of 8 novel agents over the last decade. In addition to novel pharmaceuticals, rapidly evolving diagnostic tools have emerged. This review provides a primer for clinicians who treat men with advanced prostate cancer, including medical oncologists, radiation oncologists, and urologists.

RESUMEN

AIM: Pulse width (PW) influences neuromodulation by its impact on nerve fiber recruitment. A paucity of data regarding the manipulation of PW in sacral neuromodulation (SNM) exists. This study describes the clinical features and outcomes of PW manipulation for unsatisfactory SNM therapy. METHODS: A retrospective, single-institution review was performed of reprogrammed SNM patients between 2010 and 2019. Two cohorts were created: those with PW changes ± program changes and age-matched controls with program changes alone. Patients lacking follow-up and non-InterStim II models were excluded. RESULTS: Out of 710 SNM interrogations, 147 (20.7%) had PW changes and 80 met inclusion criteria. Most PW changes were shortened (61/80, 76.3%). Clinical features did not differ between cohorts except by indication for reprogramming. The most common indication for PW change was painful stimulation (34/80, 43%), whereas in controls it was suboptimal efficacy (76/80, 95%). Clinical success was stratified by indication. There was a higher improvement in efficacy in the PW cohort (61%, 17/28 vs. 36%, 27/76, p = .02). PW manipulation successfully relieved painful stimulation in 50% (17/34 vs. 0/3, p = .23), which was more likely with a shortened compared to extended PW (14/15, 93.3% vs. 0/6, 0%, p < .01). PW resulted in improvement in localization of the stimulus in 94% (17/18 vs. 0/1, p = .10). The subsequent lead revision or explant was significantly higher in the PW cohort (43% vs. 25%, p = .03). CONCLUSION: PW manipulation may aid the salvage of unsatisfactory SNM therapy. These findings represent an initial assessment of the role of PW in SNM, particularly regarding the efficacy and painful stimuli. The further prospective investigation is warranted.

RESUMEN

OBJECTIVE: To assess readmission outcomes of a traditional ER pathway as well as a targeted postdischarge intervention aimed at reducing hospital readmissions following RC. METHODS: A prospectively maintained clinical database was used to identify patients undergoing RC before and after implementation of an ER protocol at our institution. An additional intervention aimed at reducing hospital readmission included close postdischarge follow-up and outpatient intravenous hydration (ER+). Inpatient length of stay (LOS) and readmission rates were compared between groups using Wilcoxon Rank Sum and chi-square, respectively. Univariate and multivariate logistic regression was used to identify factors associated with hospital readmission. RESULTS: A total of 320 patients underwent RC, including 111 and 209 patients before and after ER implementation. Median (IQR) LOS decreased from 8.0 (6.0-11.0) days to 5.0 (4.0-7.0) days following ER implementation (P <.0001). Readmissions, however, were unchanged following ER implementation (P = .49). An additional targeted readmission reduction intervention (ER+) was associated with significantly reduced hospital readmissions compared to traditional ER alone (ER+ 5.9%, traditional ER 20.3%, P = .017). CONCLUSION: ER protocols consistently demonstrate reductions in LOS, and should be the standard of care following RC. In order to reduce readmissions, the urologic community must expand beyond traditional ER pathways. We report significant reductions in hospital readmission among RC patients receiving a targeted postdischarge intervention beyond traditional ER alone.

RESUMEN

PURPOSE: Bladder cancer management options include open radical cystectomy and robot-assisted radical cystectomy with intracorporeal or extracorporeal urinary diversion. The existing literature shows no difference in the major complication rate between open radical cystectomy and extracorporeal urinary diversion. However, the emerging popularity of intracorporeal urinary diversion has exposed the need to compare a completely intracorporeal method to alternative approaches. To our knowledge the robotic intracorporeal advantage regarding major complications has not yet been established in an evaluation of all 3 modalities. We compared outcomes and complications of open, intracorporeal and extracorporeal cystectomy techniques at a high volume institution. MATERIALS AND METHODS: We queried a prospectively maintained database for patients who underwent radical cystectomy from 2011 to 2018 for an oncologic indication. Perioperative and pathological outcomes, and 30 and 90-day major complications were assessed. Statistical analyses were done using the Pearson chi-square, Kruskal-Wallis and Kaplan-Meier tests, and multivariable regression. RESULTS: A total of 948 patients met the study criteria, including 272, 301 and 375 treated with open radical cystectomy, intracorporeal urinary diversion and extracorporeal urinary diversion, respectively. Median followup was 26 months. Intracorporeal urinary diversion cases had lower estimated blood loss (p <0.001), shorter hospitalization (p <0.001) and a lower ileus rate (p=0.023) than extracorporeal urinary diversion and open radical cystectomy cases. Importantly, intracorporeal urinary diversion was associated with lower 30 and 90-day major complication rates vs extracorporeal urinary diversion and open radical cystectomy (90-day Clavien-Dindo III-V 16.9% vs 24.8% and 26.1%, respectively, p=0.015). There was no significant difference in the readmission rate according to the surgical approach. Multivariable predictors of increased 90-day major complications were patient age, the Charlson Comorbidity Index and operative time. On multivariable analysis intracorporeal urinary diversion was associated with reduced 90-day major complications (OR 0.58, p=0.037). CONCLUSIONS: In a 3-way comparison intracorporeal urinary diversion demonstrated a lower major complication rate and perioperative benefits compared to extracorporeal urinary diversion and open radical cystectomy.

RESUMEN

Adult human neural progenitor and stem cells have been implicated as a potential source of brain cancer causing cells, but specific events that might cause cells to progress towards a transformed phenotype remain unclear. The L1CAM (L1) cell adhesion/recognition molecule is expressed abnormally by human glioma cancer cells and is released as a large extracellular ectodomain fragment, which stimulates cell motility and proliferation. This study investigates the effects of ectopic overexpression of the L1 long ectodomain (L1LE; ˜180 kDa) on the motility, proliferation, and differentiation of human neural progenitor cells (HNPs). L1LE was ectopically expressed in HNPs using a lentiviral vector. Surprisingly, overexpression of L1LE resulted in reduced HNP motility in vitro, in stark contrast to the effects on glioma and other cancer cell types. L1LE overexpression resulted in a variable degree of maintenance of HNP proliferation in media without added growth factors but did not increase proliferation. In monolayer culture, HNPs expressed a variety of differentiation markers. L1LE overexpression resulted in loss of glutamine synthetase (GS) and ß3-tubulin expression in normal HNP media, and reduced vimentin and increased GS expression in the absence of added growth factors. When co-cultured with chick embryonic brain cell aggregates, HNPs show increased differentiation potential. Some HNPs expressed p-neurofilaments and oligodendrocytic O4, indicating differentiation beyond that in monolayer culture. Most HNP-L1LE cells lost their vimentin and GFAP (glial fibrillary acidic protein) staining, and many cells were positive for astrocytic GS. However, these cells rarely were positive for neuronal markers ß3-tubulin or p-neurofilaments, and few HNP oligodendrocyte progenitors were found. These results suggest that unlike for glioma cells, L1LE does not increase HNP cell motility, but rather decreases motility and influences the differentiation of normal brain progenitor cells. Therefore, the effect of L1LE on increasing motility and proliferation appears to be limited to already transformed cells.

RESUMEN

Pelvic organ prolapse is common in parous women, although few report symptoms. The incidence of posterior compartment prolapse, or rectocele, is less well-reported. Posterior vaginal wall prolapse is associated with pain, constipation, and splinting. Surgery is the mainstay of therapy for symptomatic rectoceles. Though several surgical techniques have been described, no clear indications for type of repair have emerged. This article reviews the management strategies and draws conclusions about suture-based and site-specific techniques.

RESUMEN

OBJECTIVE: To determine whether supplemental biopsy of hypoechoic ultrasound lesions (HUL) incidentally found during magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion-targeted prostate biopsy results in improved prostate cancer (PCa) detection. METHODS: Patients underwent MRI-TRUS-targeted biopsy as part of an ongoing prospective trial from August 2007 to February 2015. For men with HUL, the biopsy pathology of HUL and MRI lesions was classified according to the updated 2014 International Society of Urological Pathology (ISUP) grading system. The detection of PCa by MRI-targeted biopsy with and without HUL biopsy was compared. RESULTS: Of 1260 men in the trial, 106 underwent biopsy of 119 HULs. PCa was diagnosed in 52 out of 106 men (49%) by biopsy of either MRI lesions or HUL. Biopsy of HUL in addition to MRI lesions resulted in 4 additional diagnoses of high-grade (ISUP grades 3-5) PCa versus biopsy of MRI lesions alone (20 vs 16 men, P = .046). Three of these cases were upgraded from lower grade (ISUP grades 1-2) PCa on MRI-guided biopsy alone, and only 1 case (1% of cohort) was diagnosed that would have been missed by MRI-guided biopsy alone. Supplemental biopsy of HUL did not change the PCa risk category in 96% (102 out of 106) of men with HUL. CONCLUSION: Supplemental biopsy of HUL yields a small increase in the detection of higher grade PCa as compared with biopsy of MRI lesions alone. As upgrading is rare, routinely screening for HUL during MRI-targeted biopsy remains controversial.

RESUMEN

PURPOSE: We explored differences in changes in medical student empathy in the third year of medical school between volunteers at JeffHOPE, a multisite medical student-run free clinic of Sidney Kimmel Medical College (SKMC), and nonvolunteers. METHOD: Volunteerism and leadership experience at JeffHOPE were documented for medical students in the Class of 2015 (n = 272) across their medical educations. Students completed the Jefferson Scale of Empathy at the beginning of medical school and at the end of the third year. Students who reported participation in other Jefferson-affiliated clinics (n = 44) were excluded from this study. Complete data were available for 188 SKMC students. RESULTS: Forty-five percent of students (n = 85) volunteered at JeffHOPE at least once during their medical educations. Fifteen percent of students (n = 48) were selected for leadership positions involving weekly clinic participation. Nonvolunteers demonstrated significant decline in empathy in medical school ( P = 0.009), while those who volunteered at JeffHOPE at least once over the course of their medical educations did not show any significant decline ( P = 0.07). CONCLUSIONS: These findings suggest that medical students may benefit from volunteering at student-run free clinics to care for underserved populations throughout medical school.

RESUMEN

OBJECTIVES: To evaluate the utility of preoperative multiparametric magnetic resonance imaging (MP-MRI) in predicting biochemical recurrence (BCR) following radical prostatectomy (RP). MATERIALS/METHODS: From March 2007 to January 2015, 421 consecutive patients with prostate cancer (PCa) underwent preoperative MP-MRI and RP. BCR-free survival rates were estimated using the Kaplan-Meier method. Cox proportional hazards models were used to identify clinical and imaging variables predictive of BCR. Logistic regression was performed to generate a nomogram to predict three-year BCR probability. RESULTS: Of the total cohort, 370 patients met inclusion criteria with 39 (10.5%) patients experiencing BCR. On multivariate analysis, preoperative prostate-specific antigen (PSA) (p = 0.01), biopsy Gleason score (p = 0.0008), MP-MRI suspicion score (p = 0.03), and extracapsular extension on MP-MRI (p = 0.03) were significantly associated with time to BCR. A nomogram integrating these factors to predict BCR at three years after RP demonstrated a c-index of 0.84, outperforming the predictive value of Gleason score and PSA alone (c-index 0.74, p = 0.02). CONCLUSION: The addition of MP-MRI to standard clinical factors significantly improves prediction of BCR in a post-prostatectomy PCa cohort. This could serve as a valuable tool to support clinical decision-making in patients with moderate and high-risk cancers.

RESUMEN

INTRODUCTION: African-American (AA) men tend to harbor high-risk prostate cancer (PCa) and exhibit worse outcomes when compared to other groups. It has been postulated that AA men may harbor more anterior prostate lesions (APLs) that are undersampled by the standard transrectal ultrasound guided-biopsy (SBx), potentially resulting in greater degree of Gleason score (GS) upgrading at radical prostatectomy. We aimed to evaluate the detection rate of anterior PCa significance of APLs in AA men on multiparametric magnetic resonance imaging (mpMRI) and compare it to a matched cohort of White/Other (W/O) men. MATERIALS AND METHODS: A review of 1,267 men who had an mpMRI with suspicious prostate lesions and who underwent magnetic resonance transrectal ultrasound fusion-guided biopsy (FBx) with concurrent SBx in the same biopsy session was performed. All AA men were matched to a control group of W/O using a 1:1 propensity score-matching algorithm with age, prostate-specific antigen, and prostate volume as matching variables. Logistic regression analysis was used to determine predictors of APLs in AA men. RESULTS: Of the 195 AA men who underwent mpMRI, 93 (47.7%) men had a total of 109 APLs. Prior negative SBx was associated with the presence of APLs in AA men (Odds ratio = 1.81; 95% CI: 1.03-3.20; P = 0.04). On multivariate logistic regression analysis, smaller prostate (P = 0.001) and rising prostate-specific antigen (P = 0.007) were independent predictors of cancer-positive APLs in AA men. Comparative analysis of AA (93/195, 47.7%) vs. W/O (100/194, 52%) showed no difference in the rates of APLs (P = 0.44) or in cancer detection rate within those lesions or the distribution of GS within those cancers (P = 0.63) despite an overall higher cancer detection rate in AA men (AA: 124/195 [63.6%] vs. W/O: 97/194 [50.0%], P = 0.007). In cases where APLs were positive for PCa on FBx, the GS of APL was equal to the highest GS of the entire gland in 82.9% (29/35) and 90.9% (30/33) of the time in AA and W/O men, respectively. CONCLUSION: Cancer-positive APLs represented the highest risk GS in most cases. AA men with prior negative SBx are twice as likely to harbor a concerning APL. In our cohort, AA and W/O men had comparable rates of APLs on mpMRI. Thus, differences in APLs do not explain the higher risk of AA men for deahth due to PCa. However, targeting of APLs via FBx can clinically improve PCa risk stratification and guide appropriate treatment options.
