Pubertal Suppression and Surgical Management of a Patient With 5-Alpha Reductase Deficiency.

Five-alpha reductase type 2 deficiency (5αRD2) is a rare cause of atypical genitalia in newborns. There are no definitive guidelines regarding management of children with this disorder. While many children are raised as female given the under-virilized appearance of their external genitalia at birth, these patients are historically counseled to undergo male puberty, resulting in a change in gender identity from female to male in more than half of post-pubertal patients. Here we report the first case of a patient with 5αRD2who identified as female from a very early age, strongly desired gender-affirming surgery, and elected to initiate puberty-blocking therapy prior to the onset of male puberty.

Timing, Patterns and Predictors of 90-Day Readmission Rate after Robotic Radical Cystectomy.

PURPOSE: We examine the timing, patterns and predictors of 90-day readmission after robotic radical cystectomy. MATERIALS AND METHODS: From September 2009 to March 2017, 271 consecutive patients undergoing robotic radical cystectomy with intent to cure bladder cancer (intracorporeal diversion 253, 93%) were identified from our prospectively collated institutional database. Readmission was defined as any subsequent inpatient admission or unplanned visit occurring within 90 days from discharge after the index hospitalization. Multiple readmissions were defined as 2 or more readmissions within a 90-day period. Logistic regression analysis was used to identify independent factors related to single and multiple 90-day readmissions. RESULTS: A total of 78 (28.8%) patients were readmitted at least once within 90 days after discharge, of whom 20 (25.6%) reported multiple readmissions. The cumulative duration of readmission was 6.2 (6.17) days with 6 (7.6%) patients having less than 24 hours readmission. Metabolic, infectious, genitourinary and gastrointestinal complications were identified as the primary cause of readmission in 39.5%, 23.5%, 22.3% and 17%, respectively. Fifty percent of readmissions occurred in the first 2 weeks after hospital discharge. On multivariable logistic regression analysis in-hospital infections (OR 2.85, p=0.001) were independent predictors for overall readmission. Male gender (OR 3.5, p=0.02) and in-hospital infections (OR 4.35, p=0.002) were independent predictors for multiple readmissions. CONCLUSIONS: The 90-day readmission rate following robotic radical cystectomy is significant. In-hospital infections and male gender were independent factors for readmission. Most readmissions occurred in the first 2 weeks following discharge, with metabolic derangements and infections being the most common causes.

Metoidioplasty With Urethral Lengthening: A Stepwise Approach.

BACKGROUND: Metoidioplasty is a gender-affirming surgical option for individuals who desire masculine genitalia while preserving erogenous sensation and avoiding the morbidity of phalloplasty. Concurrent urethral lengthening offers patients the potential to stand to urinate. OBJECTIVE: To demonstrate an adaptation of the Belgrade technique of gender-affirming metoidioplasty and describe outcomes. METHODS: We identified 33 patients of which 12 underwent simple metoidioplasty and 21 underwent metoidioplasty with urethral lengthening between 2016 and 2020. Prior to surgery, all patients underwent at least 1 year of testosterone therapy to maximize clitoral growth. The clitoris is degloved and the superficial suspensory ligament divided to maximize phallic length. Labia minora flaps are developed and the urethral plate is divided to allow for maximal ventral extension. The resultant urethral defect is bridged with a buccal mucosa graft. To construct the ventral aspect of the urethra, an anterior vaginal wall flap and labia minora flap are sutured to the urethral plate and tubularized over a 16 Fr catheter. The medial aspect of the contralateral labia minora is de-epithelialized and overlaps the urethra, serving as ventral skin coverage for the phallic shaft. Bilateral labia majora flaps are then rotated anteriorly and superiorly to create a neoscrotum using the Ghent technique. RESULTS: For metoidioplasty with urethral lengthening, the median operative time was 408 minutes, estimated blood loss 400 mL, and length of stay 3 days. Of the 21 patients, 10 (47%) elected to undergo second stage scrotoplasty, 7 (33%) underwent testicular implant placement, and 2 (9%) required revision urethroplasty. Of the 10 patients (48%) who experienced postoperative complications, 7 were Clavien-Dindo grade I-II. There were no fistulae at a median follow-up time of 5.5 months (range 1-27.2). CONCLUSION: We provide a stepwise approach to metoidioplasty with urethral lengthening using a modified Belgrade technique, which was associated with a low rate of urethral complications.

Radical cystectomy pentafecta: a proposal for standardisation of outcomes reporting following robot-assisted radical cystectomy.

OBJECTIVE: To propose a standardisable composite method for reporting outcomes of radical cystectomy (RC) that incorporates both perioperative morbidity and oncological adequacy. PATIENTS AND METHODS: From July 2010 to December 2017, 277 consecutive patients who underwent robot-assisted RC with intracorporeal urinary diversion (UD) for bladder cancer at our Institution were prospectively analysed. Patients who simultaneously demonstrated negative soft tissue surgical margins (STSMs), ≥16 lymph node (LN) yield, absence of major (grade III-IV) complications at 90 days, absence of UD-related long-term sequelae and absence of clinical recurrence at ≤12 months, were considered as having achieved the RC-pentafecta. A multivariable logistic regression model was assessed to measure predictors for achieving RC-pentafecta. RESULTS AND LIMITATIONS: Since 2010, 270 of 277 patients that had completed at least 12 months of follow-up were included. Over a mean follow-up of 22.3 months, ≥16 LN yield, negative STSMs, absence of major complications at 90 days, and absence of UD-related surgical sequelae and clinical recurrence at ≤12 months were observed in 93.0%, 98.9%, 76.7%, 81.5% and 92.2%, patients, respectively, resulting in a RC-pentafecta rate of 53.3%. Multivariable logistic regression analysis revealed age (odds ratio [OR] 0.95; P = 0.002), type of UD (OR 2.19; P = 0.01) and pN stage (OR 0.48; P = 0.03) as independent predictors for achieving RC-pentafecta. CONCLUSIONS: We present a RC-pentafecta as a standardisable composite endpoint that incorporates perioperative morbidity and oncological adequacy as a potential tool to assess quality of RC. This tool may be useful for assessing the learning curve and calculating cost-effectiveness amongst others but needs to be externally validated in future studies.

Assessing the Impact of Time to Cystectomy for Variant Histology of Urothelial Bladder Cancer.

OBJECTIVE: To determine if the timing of radical cystectomy for variant histology of urothelial carcinoma has an impact on survival. Variant histology has been associated with aberrant behavior compared to pure urothelial carcinoma, however the timing of surgery for these patients has not been studied. MATERIALS AND METHODS: We identified 363 patients with cT2-T4N0M0 urothelial carcinoma who underwent radical cystectomy without perioperative intravesical and/or systemic therapy from 2003 to 2014. Clinicopathologic data were compared between pure urothelial carcinoma and variant histology. The time from diagnosis to radical cystectomy was analyzed as a continuous variable and dichotomized at 4-, 8-, and 12-weeks to determine impact on oncologic outcomes. RESULTS: Patients with variant histology, when compared to those with pure urothelial carcinoma, were more likely to present with extravesical disease (P <.01), be upstaged (P <.01), have lymphovascular invasion (P <.01) and have lymph node metastasis at radical cystectomy (P = .02). The median days to radical cystectomy did not differ between pure urothelial and variant histology. On multivariable analysis controlling for age, comorbidities, tumor stage, lymph node status, lymphovascular invasion, and surgical margins, every month in delay was associated with a worse overall survival for variants (HR = 1.36, P = .003). At an 8-week delay or longer, those with variant histology had a statistically worse survival (P = .03). CONCLUSION: For patients with variant histology, delays in surgery were associated with an increased risk of death.

Primary Whole-gland Cryoablation for Prostate Cancer: Biochemical Failure and Clinical Recurrence at 5.6 Years of Follow-up.

We retrospectively evaluated complications and functional and oncologic outcomes of 94 consecutive men who underwent primary whole-gland cryoablation for localized prostate cancer (PCa) from 2002 to 2012. Kaplan-Meier and multivariable Cox regression analyses were performed using a landmark starting at 6 mo of follow-up. In total, 75% patients had D'Amico intermediate- (48%) or high- (27%) risk PCa. Median follow-up was 5.6 yr. Median time to prostate-specific antigen (PSA) nadir was 3.3 mo, and 70 patients reached PSA <0.2ng/ml postcryoablation. The 90-d high-grade (Clavien Grade IIIa) complication rate was 3%, with no rectal fistulas reported. Continence and potency rates were 96% and 11%, respectively. The 5-yr biochemical failure-free survival (PSA nadir+2ng/ml) was 81% overall and 89% for low-, 78% for intermediate-, and 80% for high-risk PCa (p=0.46). The median follow-up was 5.6 and 5.1 yr for patients without biochemical failure and with biochemical failure, respectively. The 5-yr clinical recurrence-free survival was 83% overall and 94% for low-, 84% for intermediate-, and 69% for high-risk PCa (p=0.046). Failure to reach PSA nadir <0.2ng/ml within 6 mo postcryoablation was an independent predictor for biochemical failure (p=0.006) and clinical recurrence (p=0.03). The 5-yr metastases-free survival was 95%. Main limitation is retrospective evaluation. Primary whole-gland cryoablation for PCa provides acceptable medium-term oncologic outcomes and could be an alternative for radiation therapy or radical prostatectomy. PATIENT SUMMARY: Cryoablation is a safe, minimally-invasive procedure that uses cold temperatures delivered via probes through the skin to kill prostate cancer (PCa) cells. Whole-gland cryoablation may offer an alternative treatment option to surgery and radiotherapy. We found that patients had good cancer outcomes 5 yr after whole-gland cryoablation, and those with a prostate-specific antigen value ≥0.2ng/ml within 6 mo after treatment were more likely to have PCa recurrence.

Assessing trends in urinary diversion after radical cystectomy for bladder cancer in the United States.

OBJECTIVES: We assessed recent trends in both urinary diversion after radical cystectomy for bladder cancer in the United States and patient- and hospital-related characteristics. We also identified variables associated with undergoing continent diversion. MATERIALS AND METHODS: We queried the National Cancer Database and identified 27,170 patients who underwent radical cystectomy with urinary diversion from 2004 to 2013. Patient demographics, socioeconomic variables, and hospital-related factors were compared between incontinent and continent diversion and trended over time. Multivariable logistic regression was used to identify variables associated with undergoing continent diversion. RESULTS: Overall, 23,224 (85.5%) and 3,946 (14.5%) patients underwent incontinent and continent diversion, respectively. Continent diversion declined from 17.2% in 2004 to 2006 to 12.1% in 2010 to 2013 (P < 0.01). When analyzing high-volume facilities, those performing ≥75% minimally invasive radical cystectomy had fewer continent diversions (10.2%) compared to centers with higher rate of open approach (19.7%), P < 0.01. Higher income, facility located in the West, academic programs, high-volume facilities, and patients traveling >60 miles for care were significantly associated with undergoing continent diversion. Rate of continent diversion has declined in most patient- and hospital-related subgroups. Compared to 2004 to 2006, patients in 2010 to 2013 were more likely to be older, have more comorbidities, and be operated on at a high-volume academic facility. CONCLUSION: The rate of continent diversion has declined to 12.1% in the United States. Hospital volume and type, patient income, distance traveled for care, and geography are significantly associated with undergoing continent diversion. Even among high-volume and academic centers, the rate of continent diversion is declining.

Frailty as a predictor of complications after radical cystectomy: A prospective study of various preoperative assessments.

PURPOSE: Frailty has been correlated with worse postoperative outcomes. Prospective studies examining frailty and bladder cancer are lacking. We aimed to determine whether a prospective frailty assessment or traditional risk indices can identify patients undergoing radical cystectomy (RC) at risk for complications. MATERIALS AND METHODS: Patients ≥65 years undergoing RC were preoperatively assessed using Fried Frailty Criteria (FFC; grip strength, gait speed, exhaustion, physical activity, shrinking), Charlson Comorbidity Index, American Society of Anesthesiologists score, Katz Index of Independence in Activities of Daily Living, Karnofsky Performance Scale, Eastern Cooperative Oncology Group performance status, and Center for Epidemiological Studies Depression scale. Thirty-day and 90-day postoperative complications were recorded. Univariate and multivariate analyses were performed. RESULTS: One hundred and twenty three patients were assessed with median age of 74 years. Fifty-nine patients (48.0%) had ≥1 complication within 30 days and 72 (58.5%) within 90 days. Center for Epidemiological Studies Depression scale (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.01-1.17, P = 0.027) and shrinking (OR 3.79, 95% CI 1.64-9.26, P = 0.0024) were significant for any 30-day complication, while physical activity was protective (OR 0.84, 95% CI 0.69-1.00, P = 0.072) for any 90-day complication. Being intermediately frail or frail was associated with high-grade 30-day (OR 4.87, 95% CI 1.39-22.77, P = 0.022) and 90-day complications (OR 3.01, 95% CI 1.05-9.37, P = 0.045), along with Eastern Cooperative Oncology Group score ≥3 (OR 45.00, 95% CI 6.92-437.69, P = 0.0010 and OR 17.85, 95% CI 3.21-143.26, P = 0.0079, respectively). CONCLUSIONS: Fried Frailty Criteria were predictive of high-grade complications, while individual components were predictive of having any complication. Elderly patients should be routinely assessed prior to RC to guide postoperative care.

Objective Assessment of Robotic Surgical Technical Skill: A Systematic Review.

PURPOSE: Robotic surgeries, especially in urology, have grown exponentially during the last decade. Various skills assessment tools have been developed. We reviewed the current status, the current challenges and the future needs of robotic evaluations with a focus on urological applications. MATERIALS AND METHODS: According to PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) criteria 2 paired investigators screened the PubMed®, Scopus® and Web of Science® databases for all full text, English language articles published between 2006 and 2018 using the query (evaluation OR assessment) AND (robot-assisted surgery OR robotic surgery) AND (surgical performance OR surgical skill) AND training. The research design, validity and reliability of each study were ascertained and analyzed. RESULTS: A total of 259 studies were identified, of which 109 were included in the final analysis. We grouped the studies into 2 categories, including manual and automated assessments. Manual evaluation included global skill, procedure specific and error based assessments. For automated assessment we summarized evaluations derived from robotic instrument kinematic tracking data, systems events and surgical video data, and we explored those associations with various domains by manual evaluation. We further reviewed the current progress in automated surgical segmentation and skill evaluation with machine learning and deep learning. Concerns remain regarding efficient and effective surgeon training and credentialing. CONCLUSIONS: No universally accepted robotic skills assessment currently exists. The purpose of assessment (training or credentialing) may dictate whether manual or automated surgeon assessment is more suitable. Moving forward, assessment tools must be objective and efficient to facilitate the training and credentialing of competent surgeons.
