RESUMO

Long-term oncologic data on patients undergoing robot-assisted radical cystectomy (RARC) for non-metastatic bladder cancer (BCa) are limited. The purpose of this study is to describe long-term oncologic outcomes of patients receiving robotic radical cystectomy at a high-volume European Institution. We analyzed data of 107 patients treated with RARC between 2003 and 2012 at a high-volume robotic center. Clinical, pathologic, and survival data at the latest follow-up were collected. Clinical recurrence (CR)-free survival, cancer-specific mortality (CSM)-free survival, and overall survival (OS) were plotted using Kaplan-Meier survival curves. Cox proportional hazard models investigated predictors of CR and CSM. Competing-risk regressions were utilized to depict cumulative incidences of death from BCa and death from other causes after RARC at long term. Pathologic nonorgan-confined BCa was found in 40% of patients, and 7 (7%) patients had positive soft tissue surgical margins. Median (interquartile range [IQR]) number of nodes removed was 11 (6, 14), and 26% of patients had pN + disease. Median (IQR) follow-up for survivors was 123 (117, 149) months. The 12-year CR-free, CSM-free and overall survival were 55% (95% confidence interval [CI] 44%, 65%), 62% (95% CI 50%, 72%), and 34% (95% CI 24%, 44%), respectively. Nodal involvement on final pathology was associated with poor prognosis on multivariable competing risk analysis. The cumulative incidence of non-cancer death exceeded that of death from BCa after approximately ten years after RARC. We provided relevant data on oncologic outcomes of RARC at a high-volume robotic center, with acceptable rates of clinical recurrence and cancer-specific survival at long-term. In patients treated with RARC, the cumulative incidence of death from causes other than BCa is non-negligible, and should be taken into consideration for post-operative follow-up.

RESUMO

Objective: Treatment for bladder diverticula may become necessary in case of incomplete bladder emptying or recurrent urinary tract infections (UTIs). When bladder outlet obstruction is present, a simultaneous desobstructive procedure can be performed. In this video, we present our technique for a transvesical approach in robot-assisted bladder diverticulectomy (RABD) and discuss its outcomes. Patients and Surgical Procedure: We retrospectively analyzed the outcomes of 23 patients who underwent a transvesical RABD between March 2015 and May 2020 at the OLV hospital of Aalst. After retrograde filling, a cystotomy is performed. The orifices are identified and the bladder diverticulum is observed. The mucosa covering the diverticular neck is incised and the plane between the mucosa and the muscularis is identified. The mucosa is separated from the surrounding structures. The base of the diverticulum is transected using cautery. The defect is closed with a barbed suture. Results: Median age was 66 years (interquartile range [IQR] 60-69). The number of diverticula removed ranged from 1 to 3. Ten patients were treated with diverticulectomy alone, 12 underwent a simultaneous adenomectomy, 1 a radical prostatectomy. Median operative was 140 minutes (IQR 120-180), median estimated blood loss was 250 mL (IQR 28-438). Median catheterization time was 2 days (IQR 1-5), median hospitalization time 3 days (IQR 2-4). One patient developed urinary leakage after catheter removal, one patient developed a UTI. Median follow-up was 9 months (IQR 3.5-14). No late postoperative complications nor relapse were recorded. Average postvoid residual was 42 mL (IQR 0-111), with a median decline of 120 mL (IQR -402 to -33). Conclusions: Transvesical approach for RABD is a safe and reliable technique that gives the advantage of a quick localization of the diverticulum and orifices, and direct access to the prostate when simultaneous desobstruction is necessary. Catheterization time is short. No relapse has been observed.

RESUMO

We evaluated the feasibility and impact on short- and long-term functional outcomes of very early catheter removal on postoperative day (POD) 2 after robot-assisted radical prostatectomy (RARP). To the best of our knowledge, this is the first multisurgeon study with the largest cohort on very early (POD 2) catheter removal after RARP with follow-up of >1 yr. In 255/369 patients (69%) treated with RARP ±â€¯pelvic lymph node dissection, the catheter was removed on POD 2. Among the 255 patients, 33 (13%) required recatheterisation because of acute urinary retention after catheter removal. Of these 33 patients, five (2%) also experienced anastomotic leakage after catheter removal. The early (≤3 mo) urinary continence rate was 67% and the median time to urinary continence recovery was 1 mo. After median follow-up of 18 mo (interquartile range 13-24), 236 patients (88%) were continent. No anastomotic strictures occurred. Our observations confirm the feasibility and safety of POD 2 catheter removal after RARP and support its adoption for selected patients. PATIENT SUMMARY: After removal of the prostate for cancer, patients have a urinary catheter inserted. We investigated whether earlier removal of the catheter affects long-term urinary continence. The results show that it may be safe to remove the catheter on postoperative day 2 for selected patients.

RESUMO

Worldwide, we have witnessed an expansion of robot-assisted laparoscopic surgery (RALS) and thanks to the global adoption of high-resolution diagnostic imaging technologies, an increased incidence of newly diagnosed prostatic, renal and bladder cancers has been recorded with concurrent second primary urological cancer diagnoses increasing by 1.5%. Diverse authors have reported their findings concerning synchronous multi-visceral malignances robotic treatment within the scientific literature. The aim of this study is to comprehensively review all reported articles describing concurrent upper and lower RALS using a singular robotic port scheme within the same intervention for renal malignances and concomitant prostatic or bladder cancers. To the best of our knowledge and vigorous literature search, this is the first study that comprehensively evaluates and reports all combined upper and lower urinary tract surgeries published so far. In carefully selected patients, thanks to multidisciplinary preoperative assessment and surgical planning a combined robotic approach can reduce the morbidity, complications, hospital admissions and the overall length of hospitalization.

RESUMO

BACKGROUND: Pediatric cystic renal lesions are challenging to manage as little is known about their natural course. A modified Bosniak (mBosniak) classification system has been proposed for risk stratification in pediatric patients that takes ultrasound (US) and/or computed tomogram (CT) characteristics into account. However, literature validating this system remains limited. OBJECTIVE: To determine if the mBosniak classification system correlates with pathologic diagnoses. The hypothesis is that mBosniak classification can stratify the risk of malignancy in children with renal cysts. STUDY DESIGN: Patients treated for cystic renal masses with available imaging and pathology between 2000 and 2019 from five institutions were identified. Clinical characteristics and pathology were obtained retrospectively. Characteristics from the most recent US, CT, and/or magnetic resonance imaging (MRI) were recorded. Reviewers assigned a mBosniak classification to each scan. mBosniak scores 1/2 were considered low-risk and 3/4 high-risk. These groups were compared with pathology (classified as benign, intermediate, malignant). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (+LR), and negative likelihood ratio (-LR) were calculated to assess this categorization as a screening tool to guide surgical intervention. Agreement between imaging modalities was also explored. RESULTS: 99 patients were identified. High-risk imaging findings were correlated with malignant or intermediate pathology with a sensitivity of 88.3%, specificity of 84.6%, PPV of 89.8%, NPV of 82.5%, +LR of 5.7, and -LR of 0.14. The sensitivity for detecting malignant lesions only was 100%. There was substantial agreement between US/CT (n = 55; κ = 0.66) and moderate agreement between US/MRI (n = 20; κ = 0.52) and CT/MRI (n = 13; κ = 0.47). DISCUSSION: The mBos classification system is a useful tool in predicting the likelihood of benign vs. intermediate or malignant pathology. The relatively high sensitivity and specificity of the system for prediction of high-risk lesions makes this classification applicable to clinical decision making. In addition, all malignant lesions were accurately identified as mBosniak 4 on imaging. This study adds substantial data to the relatively small body of literature validating the mBosniak system for risk stratifying pediatric cystic renal lesions. CONCLUSIONS: Pediatric cystic renal lesions assigned mBosniak class 1/2 are mostly benign, whereas class 3/4 lesions are likely intermediate or malignant pathology. We observed that the mBosniak system correctly identified pathology appropriate for surgical management in 88% of cases and did not miss malignant pathologies. There is substantial agreement between CT and US scans concerning mBos classification.

RESUMO

BACKGROUND: International guidelines suggest the use of anatomic scores to predict surgical outcomes after partial nephrectomy (PN). We aimed at validating the use of Simplified PADUA Renal (SPARE) nephrometry score in robot-assisted PN (RAPN). MATERIALS AND METHODS: Three hundred and sixty-eight consecutive RAPN patients were included. Primary endpoints were overall complications, postoperative acute kidney injury (AKI) and TRIFECTA achievement. Secondary endpoint was estimated glomerular filtration rate (eGFR) decrease at last follow-up. Multivariable logistic and linear regression models were used. RESULTS: Of 368 patients, 229 (62%) vs. 116 (31%) vs. 23 (6.2%) harboured low- vs. intermediate- vs. high-risk renal mass, according to SPARE classification. SPARE score predicted higher risk of overall complications (Odds ratio [OR]: 1.23, 95%CI 1.09-1.39; P < 0.001), and postoperative AKI (OR: 1.20, 95%CI 1.08-1.35; P < 0.01). Moreover, SPARE score was associated with lower TRIFECTA achievement (OR: 0.89, 95%CI 0.81-0.98; P = 0.02). Predicted accuracy was 0.643, 0.614 and 0.613, respectively. After a median follow-up of 40 (IQR: 21-66) months, eGFR decrease ranged from -7% in low-risk to -17% in high-risk SPARE. CONCLUSIONS: SPARE scoring system predicts surgical success in RAPN patients. Moreover, SPARE score is associated with eGFR decrease at long-term follow-up. Thus, the adoption of SPARE score to objectively assess tumor complexity prior to RAPN may be preferable.

RESUMO

PURPOSE OF REVIEW: Although immediate surgical outcomes of genitourinary reconstruction used to be the main focus in hypospadias and exstrophy-epispadias complex (EEC), recent research demonstrates rising concerns about long-term functional and psychosexual outcomes. Recent results about long-term outcomes of complex genitourinary reconstruction in those children transitioning into adulthood are summarized and discussed in this comprehensive review. RECENT FINDINGS: Long-term outcomes in hypospadias focus on psychosexual satisfaction and decisional regret. Interestingly, uncomplicated hypospadias repair results in equal satisfaction rates to those found in controls. Most adult patients are happy with their parents' decision to have them undergo surgery during childhood. No decisional regret was found in parents. Reinterventions were associated with a decline in satisfaction, as was a decrease in perceived penile length. Long-term, males with EEC are more dissatisfied with penile length than with continence problems. In cases of severe penile insufficiency, phalloplasty shows promising psychosexual outcomes at the price of a high complication rate. Female EEC patients show higher rates of pregnancy complications, portending a higher risk of miscarriage. SUMMARY: Psychosexual satisfaction of patients with repaired hypospadias transitioning into adulthood demonstrates equal satisfaction rates to those found in controls, without decisional regret associated with surgery during childhood. In EEC, more complications are seen when transitioning into a sexually active adult life.

RESUMO

BACKGROUND: Possible options of genital gender affirming surgery in transmasculine are metoidioplasty or phalloplasty. As opposed to phalloplasty, no flapbased neophallic reconstruction is needed in metoidioplasty. Urethral lengthening is needed in metoidioplasty if the patient desires voiding at the tip of the neophallus. This urethral lengthening poses the patient at risk for urethral complications. AIM: Our primary goal was to describe the morbidity and specific the urethral complications related to metoidioplasty. Second, we sought for predictors of these urethral complications. METHODS: Our institutional database was retrospectively analyzed to identify transmasculine who underwent metoidioplasty between 2006 and 2020. This cohort was further evaluated for surgical morbidity, urethral complications and potential predictors for urethral complications. OUTCOMES: The rate of surgical morbidity and urethral complications (temporary/permanent fistula, stricture or fistula and stricture) was calculated. Potential predictors evaluated herein were BMI, concomitant vaginectomy, active smoking and additional urethral lengthening (AUL). They were tested with logistic regression analysis with calculation of Odds Ratio (OR). RESULTS: Seventy-four patients underwent metoidioplasty with a median follow-up of 44 months. Median age was 26 years. AUL was done in 36 (48.6%) patients and established by a transverse preputial skin island and labium minus flap in respectively 34 and 2 patients. Within 30 days after metoidioplasty, 3 (4.1%) high-grade complications were noted. Urethral complications of any kind were noted in 42 (56.8%) patients. All fistulas, permanent fistulas and strictures were seen in resp. 34 (45.9%), 27 (36.5%) and 14 (18.9%) patients. AUL is a significant predictor for all urethral complications (OR 15.5), strictures (OR 24.5), all fistula's (OR 6.07) and permanent fistulas (OR 3.83). In contrast, smoking is only a predictor for all fistulas (OR 6.54) and permanent fistulas (OR 3.76). CLINICAL IMPLICATIONS: Obtaining information about the risk of complications is important in preoperative patient counselling. Patient who desires AUL are at higher risk to develop urethral complications and patients who continue to smoke at the period of metoidioplasty have a higher risk of fistula formation. STRENGTH & LIMITATIONS: Sufficient events to calculate predictors for urethral complications. However, this is a retrospective study with still a small number of patients with a relative short follow-up. CONCLUSION: Urethral complications are frequent after metoidioplasty and approximately 50% needs corrective surgery. AUL is an independent risk factor for fistula and stricture formation, whereas smoking is a risk factor for fistula formation. Waterschoot M, Hoebeke P, Verla W, et al.

RESUMO

INTRODUCTION: Scarce data is available in literature about the upper urinary tract outcomes of patients with Exstrophy-Epispadias Complex (EEC). After bladder closure during childhood, EEC bladders can become hostile to the upper tracts after bladder by exposing them to high pressures, leading to hydronephrosis (HN) and kidney damage. Similarly, vesicoureteral reflux (VUR) may be present and increase the likelihood for pyelonephritis. OBJECTIVE: We sought to assess long-term upper urinary tract outcomes by evaluating renal function, HN and VUR; and to assess if upper urinary tract outcomes are associated with continence status. STUDY DESIGN: A retrospective review of EEC patients having ≥1 surger(y) (ies) at our institution from 1990 until 2019 was performed. Renal function was assessed by evaluating last available estimated glomerular filtration rate (eGFR) and creatinine values. HN was assessed on ultrasound and classified according to the SFU-classification. Patients with recurrent febrile urinary tract infections (UTI) or pyelonephritis underwent a voiding-cystourethrogram (VCUG) assessing VUR, graded following the 'International system of radiographic grading of VUR'. Descriptive and comparative statistical analysis were performed to assess if upper tract outcomes are associated with continence status. RESULTS: Forty-eight patients (75% male) had a median (IQR) follow-up of 18 (10-21) years. The table shows upper tract outcomes for the entire group and stratified by continence status. The median creatinine was 0.6 (0.2-0.9) mg/dL and median eGFR was 108 (72-160) mL/min/1.73 m [2]. In two patients (4.2%), HN (SFU-grade 2) was detected. Thirty-six patients (75%) underwent VCUG, revealing high-grade VUR (stage IV-V) in 8 patients (17%) and low-grade VUR (stage I-III) in 7 patients (15%). Continence was associated with a higher need for VCUG (p = 0.02) and a higher presence of VUR (p = 0.03). DISCUSSION: Renal function in EEC patients and non-EEC patients is comparable when age matched. Only 6% had low-grade HN which was asymptomatic. 17% had high-grade VUR, which is little compared to literature (40-70%). However, results in literature are described in patients with a 'one-stage' bladder closure, whereas some of our patients had a 'two-stage' procedure. A one-stage procedure creates higher bladder pressures resulting in higher VUR-rates. Statistical analysis has showed that continence is associated with a higher prevalence of recurrent febrile UTI's or pyelonephritis and of VUR. CONCLUSIONS: No statistically differences were found between continent and incontinent patients concerning creatinine and eGFR value (p = 0.52 and p = 0.29), nor in the prevalence of hydronephrosis (p = 0.36). However, results of this study suggest that continent patients may portend a higher risk of upper tract deterioration with recurrent febrile UTI's and pyelonephritis due to VUR. Close monitoring of the upper tract status is therefore as important as focus on continence. Large-scale prospective studies defining renal function as well as pyelonephritis rates are needed to optimize the management of the upper tracts in EEC patients.

RESUMO

Kidney transplantation is universally recognized as the gold standard treatment in patients with End-stage Kidney Disease (ESKD, or according to the latest nomenclature, CKD stage 5). Robot-assisted kidney transplantation (RAKT) is gradually becoming preferred technique in adults, even if applied in very few centra, with potentially improved clinical outcomes compared with open kidney transplantation. To date, only very few RAKT procedures in children have been described. Kidney transplant recipient patients, being immunocompromised, might be at increased risk for perioperative surgical complications, which creates additional challenges in management. Applying techniques of minimally invasive surgery may contribute to the improvement of clinical outcomes for the pediatric transplant patients population and help mitigate the morbidity of KT. However, many challenges remain ahead. Minimally invasive surgery has been consistently shown to produce improved clinical outcomes as compared to open surgery equivalents. Robot-assisted laparoscopic surgery (RALS) has been able to overcome many restrictions of classical laparoscopy, particularly in complex and demanding surgical procedures. Despite the presence of these improvements, many challenges lie ahead in the surgical and technical-material realms, in addition to anesthetic and economic considerations. RALS in children poses additional challenges to both the surgical and anesthesiology team, due to specific characteristics such as a small abdominal cavity and a reduced circulating blood volume. Cost-effectiveness, esthetic and functional wound outcomes, minimal age and weight to undergo RALS and effect of RAKT on graft function are discussed. Although data on RAKT in children is scarce, it is a safe and feasible procedure and results in excellent graft function. It should only be performed by a RAKT team experienced in both RALS and transplantation surgery, fully supported by a pediatric nephrology and anesthesiology team. Further research is necessary to better determine the value of the robotic approach as compared to the laparoscopic and open approach. Cost-effectiveness will remain an important subject of debate and is in need of further evaluation as well.

RESUMO

BACKGROUND: Radiation therapy (RT) for prostate cancer (PCa) treatment is burdened by high rates of late urinary adverse events (UAEs). The feasibility of robot-assisted cystectomy (RAC) with intracorporeal urinary diversion (ICUD) for treatment of high-grade UAEs has never been assessed. OBJECTIVE: To report perioperative outcomes, early (≤90 d) and late (>90 d) complications among patients undergoing RAC for UAEs after RT. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively evaluated 32 patients undergoing RAC with ICUD for UAEs in a single tertiary centre. SURGICAL PROCEDURE: Surgery was performed using a da Vinci Xi system with adaptation for the primary treatment. MEASUREMENTS: Perioperative outcomes included estimated blood loss (EBL), operative time (OT), intraoperative complications, and length of stay (LOS). Data for early and late postoperative complications were collected using the quality criteria recommended by the European Association of Urology. Univariate logistic regressions were performed to test the effect of baseline and perioperative characteristics on early postoperative complications. RESULTS AND LIMITATIONS: The median age-adjusted Charlson comorbidity index (ACCI) was 6 (IQR 5-7). The indication for RAC was hemorrhagic radiation cystitis in 29 cases (91%), contracted bladder in two cases (6.2%), and urinary fistula in one case (3.1%). The median EBL, OT, and LOS were 250 ml, 330 min, and 10 d, respectively. A total of 31 (97%) patients received an ileal conduit. The 90-d rate of Clavien-Dindo grade ≥IIIa complications was 28%. The late complication rate was 46% and the perioperative mortality rate was 0%. On univariate analyses, ACCI was the only parameter correlated with the risk of early complications (odds ratio 1.75, 95% confidence interval 1.05-2.9; p = 0.03). The median follow-up was 30 mo (IQR 15-40). The lack of comparison with open cystectomy represents the main limitation. CONCLUSIONS: RAC for UAEs in patients with a history of pelvic irradiation is a feasible option in high-volume centers. The use of new technologies can help to overcome some of the technical difficulties and reduce the risk of perioperative and late complications. PATIENT SUMMARY: We report our experience with robot-assisted surgery for removal of the bladder in the management of urinary problems after radiation therapy for prostate cancer. When performed by highly experienced surgeons, this is a feasible procedure with outcomes and early and late complication rates that are acceptable.

RESUMO

Gaining an esthetical skin coverage can be challenging in some hypospadias repair cases, especially in those with significant ventral skin paucity. A local institutional technique used to correct ventral skin paucity in hypospadias is described. It consists of a redistribution of the abundant dorsal skin and its hooded prepuce to the ventral side of the penis where skin shortage is observed. Reallocation of the skin is performed by buttonholing the dorsal skin to the ventral side. This versatile technique can be adapted to most penile surgeries where some ventral skin paucity is observed.

RESUMO

BACKGROUND: The feasibility and safety of robot-assisted radical cystectomy (RARC) may be undermined by unfavorable preoperative surgical characteristics such as previous prostate surgery (PPS). OBJECTIVE: To compare perioperative outcomes for patients undergoing RARC with versus without a history of PPS. DESIGN, SETTING, AND PARTICIPANTS: The study included 220 consecutive patients treated with RARC and pelvic lymph node dissection for bladder cancer at a single European tertiary centre. Of these, 43 had previously undergone PPS, defined as transurethral resection of the prostate/holmium laser enucleation of the prostate (n=21) or robot-assisted radical prostatectomy (n=22). SURGICAL PROCEDURE: RARC in patients with a history of PPS. MEASUREMENTS: Data on postoperative complications were collected according to the quality criteria for accurate and comprehensive reporting of surgical outcomes recommended by the European Association of Urology guidelines. Multivariable logistic, linear, and Poisson regression analyses were performed to test the effect of PPS on surgical outcomes. RESULTS AND LIMITATIONS: Overall, 43 patients (20%) were treated with RARC after PPS. Operative time (OT) was longer in the PPS group (360 vs 330min; p<0.001). Patients with PPS experienced higher rates of intraoperative complications (19% vs 6.8%) and higher rates of 30-d (67% vs 39%), and Clavien-Dindo >3 (33% vs 16%) postoperative complications (all p<0.05). Moreover, the positive surgical margin (PSM) rate after RARC was higher in the PPS group (14% vs 4%; p=0.03). On multivariable analyses, PPS at RARC independently predicted higher risk of intraoperative (odds ratio [OR] 2.10, 95% confidence interval [CI] 1.04-6.21; p=0.01) and 30-d complications (OR 2.26, 95% CI 1.05-5.22; p=0.02), as well as longer OT (relative risk [RR] 1.03, 95% CI 1.00-1.05; p=0.02) and length of stay (RR 1.13, 95% CI 1.02-1.26; p=0.02). Lack of randomization represents the main limitation. CONCLUSIONS: RARC in patients with a history of PPS is feasible, but it is associated with a higher risk of complications and longer OT and length of stay. Moreover, higher PSM rates have been reported for these patients. Thus, measures aimed at improving surgical outcomes appear to be warranted. PATIENT SUMMARY: We investigated the effect of previous prostate surgery (PPS) on surgical outcomes after robot-assisted removal of the bladder. We found that patients with PPS have a higher risk of complications and longer hospitalization after bladder removal. These patients deserve closer evaluation before this type of bladder operation.

RESUMO

PURPOSE: To review existing literature about fertility and sexuality of boys born with complex congenital genitourinary anomalies. METHODS: A Pubmed review was performed in December 2018 to identify the most relevant original manuscripts regarding male complex congenital conditions affecting the urogenital system in male patients including spina bifida (SB), bladder exstrophy-epispadias complex (BEEC) and hypospadias. A comprehensive review was drafted exploring sexual dysfunction from a medical, psychosexual, surgical and reproductive point of view during transition from childhood (or adolescence) to adulthood. RESULTS: About 75% of men with SB have erectile dysfunction (ED) (Gamé et al. in Urology 67(3):566-570, 2006; Diamond et al. in 58(4):434-435, 1986). Most SB patients have impaired sexual development mainly due to diminished self-esteem, dependence on caregivers and lack of privacy (Blum et al. in Pediatrics 88(2):280-285, 1991). Men with BEEC have fewer intimate relationships than women because of the greater difficulties with issues regarding their genitalia and sexual activities (Deans et al. in Am J Obstet Gynecol 206(6):496.e1-496.e6, 2012). However, a good quality of life is achievable with the effective use of coping strategies (Deng et al. in Transl Androl Urol 7:941, 2018; Rikken et al. in BMC Womens Health 18(1):163, 2018; Friedler et al. in Reprod Biomed Online 32(1):54-61, 2016). Chordee occurs in 25% of all hypospadias patients. More severe hypospadias is related to a greater risk for complications. The long-term sexual quality of life (QoL) in men who underwent hypospadias surgery is influenced by a lot of factors. Therefore, an interactive and dynamic biopsychosocial model of sexual QoL was proposed. CONCLUSIONS: The care of patients with congenital urologic conditions becomes a challenge especially in the period of 'transition'. The goal of follow-up is a holistic management viewed from a medical, psychosexual, surgical end reproductive point. All patients should be asked for specific urinary, fecal or sexual concerns.

RESUMO

Exstrophy-epispadias complex (EEC) is a spectrum of genitourinary malformations that ranges in severity and affects external genitalia and the lower urinary tract. The aim of this study was to determine the long-term sexual outcomes of patients with EEC. Sexual outcomes were hypothesized to be related to those of urinary ones. A retrospective database including all patients with EEC who had surgery at a tertiary referral institution from 1990 to 2019 was created. Data based on patient's charts were collected: demographics, surgeries, sexual outcomes, urinary outcomes. Fifty-eight patients with EEC had surgery at tertiary referral institution and entered our database. For this analysis of sexual outcomes, a sub-set of the whole population was selected: patients being 14 years old and older, having at least one surgery at our institution and having at least 12 months of follow-up. Applying this selection criteria to our database resulted in a series of 29 patients. High rates of sexual activity were observed in pubertal and post-pubertal men (96%) and women (75%). Seventy-nine percent of men and 67% of women reported sexual satisfaction; 63% of men reported normal ejaculation. To achieve these rates, 96% of men required surgery (84% penoplasty, 52% phalloplasty), and 25% of women required introitoplasty. Fertility was achieved in 67% of men and 100% of women. Assisted reproductive technology was needed in one man. Continence rates were high (diurnal continence in 83% and nocturnal continence in 93%). However, 76% required multiple continence procedures. Men and women with EEC can have good long-term sexual and urinary outcomes, but this may require multiple surgeries. Good sexual outcomes seem to be related to good urinary and continence outcome.

RESUMO

Phalloplasty is the gold-standard treatment for cis-men with penile insufficiency, which is often secondary to congenital conditions. The study-objective is to evaluate the functional outcomes and surgical complications in this population. A retrospective database comprised of cis-men undergoing a phalloplasty at a tertiary referral center from 2004 to 2019 was created. Phalloplasty was performed with various flaps. The tube-within-tube-technique was used for urethroplasty when possible. Complications <30 days postoperative were categorized according to Clavien-Dindo. Functional outcomes were assessed by bladder emptying and ability to achieve orgasm. Thirty patients were included. Nineteen of them needed urethroplasty, the remaining 11 patients had a catheterizable stoma. Within 30 days postoperative, 3 patients (10%) developed partial-flap necrosis (Clavien-Dindo III), 1 patient (3.3%) developed graft failure (Clavien-Dindo III), 2 patients (6.6%) developed infected hematomas (Clavien-Dindo III) and 1 phalloplasty (3.3%) was complicated by hematuria (Clavien-Dindo II). In the long-term, 10 patients (33%) developed fistulae, 6 (20%) requiring urethroplasty. Seven patients (23%) had urethral strictures, all needing urethroplasty or urethrotomy. Sixteen patients (84%) emptied their bladder per urethra, the three remaining necessitated conversion to perineostomy. Median (IQR) Qmax on uroflow was 15.7 (11.9-19.2)mL/s with median (IQR) voiding volume of 259 (137-307) mL and median (IQR) residual volume of 11.5 (0-20) ml on ultrasound. All patients but 1 (97%) reported ability to achieve orgasm. RFFA and ALT result in phalli with great ability to achieve orgasm but urethral complications are frequent.

RESUMO

INTRODUCTION: Phalloplasty for penile insufficiency in biological men differs from trans-men by incorporating native tissue. The study objective was to report surgical and functional outcomes of phalloplasty in biological men. PATIENTS & METHODS: Phalloplasty was performed with a radial free forearm (RFFA) or pedicled anterolateral thigh (ALT) flap. The tube-within-tube technique was used for urethroplasty. Complications <30 d postoperative were categorized according to Clavien-Dindo. RESULTS: 30 patients, median (IQR) age of 21 (18-30)y, were included. 17 patients (57%) had penile insufficiency due to exstrophy or hypospadias surgeries, 7 patients (23%) due to sexual development disorders. In 16 patients RFFA was used. 19 patients needed urethroplasty, the rest catheterized through stoma. Median follow-up was 33 (14-80)mo. Within 30 d postoperative, 1 patients (3.3%) had Clavien-Dindo II and 6 patients (20%) Clavien-Dindo III complications. On long-term, 10 patients (33%) developed fistula, 6 needing urethroplasty. 7 patients (23%) had urethral strictures, all needing surgical intervention. All patients but one (98%) had erogenous sensitivity in the neo-phallus. All urethroplasty patients reported antegrade ejaculation. 16 patients (84%) voided through the urethra. 21 patients (70%) had an erectile device implanted. CONCLUSION: RFFA and ALT result in good erogenous sensitivity but fistulas and strictures are frequent.

RESUMO

OBJECTIVE: To report long-term surgical outcomes after urethroplasty for failed hypospadias repair (FHR) related strictures in adults. MATERIALS AND METHODS: A database of all adult (≥18 years) men who underwent urethroplasty since 2000 at Ghent University Hospital was created (prospective data since 2008). Patients with a follow-up <1 year or non-FHR related strictures were excluded. Postoperative complications were categorized according to Clavien-Dindo (<90 days), high-grade being ≥ grade 3. Failure was defined as stricture recurrence at the site of reconstruction requiring additional urethral manipulation. For penile strictures, outcomes were stratified per surgical technique. RESULTS: In total, 85 patients were included with a median (IQR) follow-up of 89 (57-165) months. Respectively 76, 6 and 3 patients had a penile, bulbar and penobulbar stricture. Postoperative complication rate was 27%. High-grade complications were seen in 7 of 85 (8.2%) patients and in 4 of 85 (4.7%) patients this involved fistula formation. Failure occurred in 29 of 85 (34%) patients, corresponding with a failure-free survival estimate (SD) of 82% (4.1), 73% (5.0) and 57% (6.7) after respectively 1, 5 and 10 years. For penile strictures, anastomotic repair had the highest failure rate (5/7, 71%) and a first stage Johanson procedure only had the lowest failure rate (1/10, 10%), followed by definitive perineal urethrostomy (1/4, 25%), pedicled flap urethroplasty (2/8, 25%) and free graft urethroplasty (7/23, 30%). CONCLUSION: FHR related strictures are predominantly seen in the penile urethra. Failure rate after urethroplasty for FHR related strictures increases steadily over time suggesting prolonged follow-up in these patients. For penile FHR related strictures, anastomotic repair should be discouraged.

RESUMO

BACKGROUND AND OBJECTIVE: Differences of sexual development (DSD) affect the development of internal reproductive organs and external genitalia. Ectopic kidney is a rare and challenging pathology causing amongst others incontinence and recurrent urinary tract infections. Those pathologies may in certain cases be an indication for surgery. This manuscript aims to evaluate the role of robot-assisted laparoscopy in the surgical treatment of patients with ectopic kidneys or DSD. MATERIALS AND METHODS: A prospective database is maintained in a tertiary referral center with all robotic surgeries performed in children. From this database, a prospective series of robot-assisted resection of embryologic remnants located in the pelvis was extracted: resection of a prostatic utricle cyst, removal of ectopic non-functional kidneys, and resection of a hemi-uterus. RESULTS: From an initial database including 72 patients, six patients met the inclusion criteria. Three male patients presenting with utricle cysts, two young girls presenting with ectopic kidneys, and one young boy with pelvic embryological remnants of the uterus, were further evaluated. CONCLUSION: Surgical treatment of patients with DSD is safe, feasible, and a good indication for robot-assisted laparoscopic surgery, as both deep dissection and reconstruction in a limited surgical field are requested.
