Phalloplasty in biological men with penile insufficiency

The Summary 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

Pediatric challenges in robot-assisted kidney transplantation

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

Long-term outcome of urethral and genital reconstruction in hypospadias and exstrophy-epispadias complex

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. 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

Long-term fate of the upper urinary tract and its association with continence in exstrophy patients

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 highgrade VUR (stage IV-V) in 8 patients (17%) and lowgrade 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 lowgrade HN which was asymptomatic. 17% had highgrade 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 VURrates. 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

Long-term sexual outcomes in patients with exstrophy-epispadias complex

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

How I do it : buttonholing the preputial hood in hypospadias repair-related ventral skin shortage

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

Rare and special robotic surgery indications in the pediatric population : ectopic organs and differences of sexual development

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

Urethral duplication as cause of incontinence in a 5-years-old female : surgical approach

Introduction Duplication of the urethra is a rare congenital anomaly in females which, if left unidentified, might cause refractory urinary incontinence. This video demonstrates its identification and treatment. Patient & methods A 5-year-old female was referred for primary re-fractory diurnal incontinence without any dry moment since birth. Initial clinical examination showed permanent urine leakage from an opening cranial to the clitoris. Ultrasound did not show any bladder or kidney abnormalities. A diagnostic cystoscopy under anesthesia revealed an accessory meatus located cranially to the orthotopic meatus and to the clitoris. Results Lying in dorsal decubitus under general anesthesia, catheters were inserted in respectively the orthotopic and accessory meatus. The accessory meatus and urethra were dissected away into the bladder dome from a circumferential skin incision. Defects were closed and bladder drainage per urethram was left in situ for 10 days. P ostoperative recovery was uncomplicated. Complete resolution of the incontinence was immediately achieved at catheter removal. Daytime and night-time continence are observed with 3 years follow-up. Conclusion Urethral duplication is a rare finding in females but should be excluded during the workup of primary incontinence. In girls with isolated urethral duplication, resection of the accessory urethra is the best surgical option
