Background: Prune belly syndrome (PBS) is characterized by the triad of abdominal flaccidity, bilateral undescended testicles and genitourinary tract anomalies. A variable spectrum of abdominal wall laxity is observed in PBS. We present the first case of a novel technique using a minimally invasive abdominoplasty to specifically address patients with localized abdominal wall weakness in PBS.

However, the south/southeast regions of Brazil are known to have a high incidence of PACTs because of the founder effect associated with a germline pathogenic variant of tumor suppressor gene TP53. We aimed to retrospectively analyze the types of variables among hormone production, radiological imaging, tumor staging, histological and genetic features that were associated with the occurrence of malignancy in 95 patients (71% females) with PACTs from a unique center.

The expression of different miRNAs in many organs of the male genital system has been reported, and these miRNAs have been associated with testicular function and its disorders, but no description has been related to DSD conditions.

Early surgical creation of a neophallus is recommended to reinforce the child's male gender-identity, favoring proper psychosexual development. Modern microsurgical techniques used to create a neophallus in adults are not recommended in children due to the invasiveness and complexity of the procedures, along with high complication rates.

Tissue inhibitor metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) indicate renal cell stress and are associated with cell cycle arrest. The [TIMP-2] [IGFBP7] ratio (Nephrocheck®) has been recently applied in patients in intensive care units patients to predict the development of acute kidney injury.

Most cases of PBS are sporadic and have a normal karyotype, with 95% patients being male. In the last decade, mutations in known genes that regulate embryonic genitourinary myogenesis have been identified and with increasing knowledge of these critical genes involved in bladder maldevelopment, advances can be made in genetic counseling.

Urinary biomarkers have been proposed as noninvasive tools. Extracellular matrix (ECM) proteins are associated with tissue fibrosis in the setting of UPJO and is poorly explored.

Upper-pole nephrectomy is a widely accepted procedure to correct symptomatic duplex systems with poor functioning moieties, also known as upper or proximal approach. The distal ureteral stump syndrome (DUSS) can be a late complication of this approach.

Patients And Methods: This study included 25 children (52% girls) with PPGL.
Introduction: The benefits of laparoscopic total nephrectomy in pediatric patients are well established. Traditional Ports placement (TPP) still follows Clayman's classic description: except for the umbilical scar, the other laparoscopic scars are exposed in the abdomen. Advances in robotic surgery permitted the development of HidES (hidden incision endoscopic surgery) technique, to obtain a better final cosmetic aspect with the scars located intraumbilically and in the hypogastric region, in an area easily hidden by underwear.

Material And Methods: We did a retrospective chart review of all children with hormonally active adrenal tumors evaluated at the endocrinology clinic and operated at our institution between 1983 and 2019.
Results: There were 75 patients included in the study, 58 with adrenocortical tumors (ACTs) and 17 with pheochromocytomas (PCCs).
Introduction: Prune Perineum Syndrome (PPS) is rare, with only three cases described in the literature. Treatment requires abdominal and pelvic surgeries. Our goal is to provide a video with steps of the surgical corrections of this syndrome.

Methods: We contacted all PBS patients 14 years old or older treated and followed at our institution. Age at orchiopexy, type of orchiopexy (with or without ligation of gonadal vessels), testicular volumes and positions were evaluated.

Differences/disorders of sex development (DSD) are a heterogeneous group of congenital conditions that result in discordance between an individual's sex chromosomes, gonads, and/or anatomic sex. Advances in the clinical care of patients and families affected by 46,XY DSD have been achieved since publication of the original Consensus meeting in 2006. The aims of this paper are to review what is known about morbidity and mortality, diagnostic tools and timing, sex of rearing, endocrine and surgical treatment, fertility and sexual function, and quality of life in people with 46,XY DSD.

We demonstrate the Single-Stage Abdominoplasty using Groin Flap technique to close the abdominal wall of children with classic bladder exstrophy (CBE) without osteotomy neither radical soft tissue mobilization. Advantages over current techniques are less risk of penile tissue loss and avoidance of osteotomies.

Introduction: Ureteropelvic junction obstruction (UPJO) is a common congenital anomaly leading to varying degrees of hydronephrosis (HN), ranging from no apparent effect on the renal function to atrophy. Evaluation of these children is based on Diuretic Renal Scintigraphy (DRS) and Ultrasonography (US). Recent studies have suggested that new parameters of conventional and color Doppler ultrasonography (CDUS) may be useful in discriminating which kidneys are obstructed.

The natural step forward is to offer the benefits of a minimally invasive technique for surgery, which is an obligatory part of treatment. Nevertheless, some authors resist using videolaparoscopic radical nephrectomy (VRN) because of concerns about reducing the cure index.

Purpose: Genital reconstruction in female patients with virilizing congenital adrenal hyperplasia (CAH) is very challenging. Our aim was to evaluate the techniques employed to treat complications after failure of primary urogenital sinus (UGS) surgery, as well as the result of these reoperations.
Patients And Methods: Twenty girls with virilizing CAH who were previously submitted to genitoplasty in our service and elsewhere had recurrent UGS stenosis and vaginal introitus stenosis that required surgical treatment.
