The most common sites of ureteral obstruction in children are at the level of the ureteropelvic junction (UPJ) and ureterovesical junction (UVJ). Bilateral hydronephrosis or hydroureteronephrosis due to varying degrees of obstruction at the UPJ or UVJ is common in children and typically improves with time. Clinically significant obstruction at both locations in an ipsilateral ureter occurs less commonly and rarely requires both dismembered pyeloplasty and ureteral reimplantation. We believe this case report is the first description of bilateral proximal and distal ureteral obstruction requiring both dismembered pyeloplasty and ureteral reimplantation...

Congenital anomalies of the kidney and urinary tract (CAKUT) represent structural and functional urinary system malformations and take place as one of the most common congenital malformations with an incidence of 1:500. Ureteral obstruction-induced hydronephrosis is associated with renal fibrosis and chronic kidney diseases in the pediatric CAKUT. We aimed to construct interaction network of previously bioinformatically associated miRNAs with CAKUT differentially expressed genes in order to prioritize those associated with fibrotic process and to experimentally validate the expression of selected miRNAs in CAKUT patients compared to control group...

OBJECTIVE: To apply and reproduce this scoring system in our prenatal hydronephrosis (PHN) population with UPJO-like HN, specifically looking at determining better HHS cutoffs that would allow for stratification into 3 risk categories: spontaneous HN resolution, observation, and surgery. METHODS: A prospectively collected prenatal hydronephrosis database was reviewed to extract UPJO-like HN patients. Children with VUR, primary megaureter, bilateral HN and other associated anomalies were excluded...

AIMS: Villanueva challenged Paquin's 5:1 tunnel length and showed in a computer simulation model that UVJ competence was more sensitive to a 2-mm protrusion of ureteric orifice into the bladder compared to an increase in the intravesical tunnel. Thompson later successfully applied the Shanfield technique of invaginating the spatulated primary obstructed megaureter (POM) laparoscopically, causing a nipple antireflux mechanism. In this study we have reported the outcomes of our modification: Nipple Invagination Combined Extravesical (NICE) reimplantation, in the management of POM...

BACKGROUND: Congenital obstructive uropathy (COU) is a common cause of developmental defects of the urinary tract, with heterogeneous clinical presentation and outcome. Genetic analysis has the potential to elucidate the underlying diagnosis and help risk stratification. METHODS: We performed a comprehensive genomic screen of 733 independent COU cases, which consisted of individuals with ureteropelvic junction obstruction (UPJO; n=321), ureterovesical junction obstruction/congenital megaureter (UVJO; n=178), and congenital hydronephrosis not otherwise specified (COU-NOS; n=234)...

The aim of the study was to evaluate whether serum aldosterone levels or plasmatic renin activity (PRA) measured early in life (1-3 months) could predict a future surgical intervention for obstructive congenital anomalies of kidney and urinary tract (CAKUT). Twenty babies aged 1-3 months of life with suspected obstructive CAKUT were prospectively enrolled. The patients underwent a 2-year follow-up and were classified as patients needing or not needing surgery. In all of the enrolled patients, PRA and serum aldosterone levels were measured at 1-3 months of life and were evaluated as predictors of surgery by receiver-operating characteristic (ROC) curve analysis...

BACKGROUND AND OBJECTIVE: Primary obstructive megaureter (POM) has various courses in different age populations. Although open ureteral reimplantation (OUR) remains the standard treatment for symptomatic POM, it is highly invasive with potential complications. In recent years, minimally invasive ureteral reimplantation (MIUR), including laparoscopic ureteral reimplantation (LUR) and robotic-assisted laparoscopic ureteral reimplantation (RALUR), and endoscopic management, such as double-J stent insertion, endoureterotomy and endoscopic balloon dilatation (EBD), have been utilized for POM in selected patients...

BACKGROUND: Congenital anomalies of the kidney and urinary tract (CAKUT) are significant causes of pediatric morbidity and mortality. The spectrum of CAKUT can be part of a syndrome, but most of these abnormalities occur as isolated and sporadic forms. The etiology of human CAKUT is unknown in the majority of cases. This case-control study aimed to investigate the association between maternal characteristics and the occurrence of CAKUT and specific CAKUT phenotypes. METHODS: In this case-control study, 29,653 newborns were evaluated consecutively in a tertiary neonatal unit using the Latin American Collaborative Study of Congenital Malformations (ECLAMC) registry...

OBJECTIVE: To evaluate the utilization of double-J stents in children with congenital hydronephrosis in order to avoid or postpone more invasive surgical intervention. Numerous studies have demonstrated that congenital hydronephrosis caused by ureteropelvic junction obstruction (UPJO) or primary obstructive megaureter (POM) may require a surgical correction in up to 20% of cases. METHODS: All infants with severe hydronephrosis and/or an obstructive pattern on renal scintigraphy that received double-J stent placement between 2010 to 2015 in our center were analyzed...
