OBJECTIVE: Urinary retention following robotic-assisted laparoscopic extravesical ureteral reimplantation (RALUR) is proposed to be due to traction or injury of the pelvic parasympathetic nerve plexus during distal ureteral dissection. Nerve-sparing techniques have been employed to avoid injury to the pelvic plexus, either directly or indirectly. This single-center study assessed postoperative urinary retention rates after extravesical RALUR and investigated whether demographic or operative factors could predict this occurrence...

BACKGROUND: We have noted a large number of referrals for abnormal kidney imaging and laboratory tests and postulated that such referrals have increased significantly over time. Understanding changes in referral patterns is helpful in tailoring education and communication between specialists and primary providers. METHODS: We performed a retrospective chart review of new patient referrals to Mary Bridge Children's Nephrology clinic for early (2002 to 2004) and late (2011 to 2013) cohorts...

PURPOSE: Ureteropelvic junction obstruction (UPJO) is one of the most common causes of hydronephrosis other than transient hydronephrosis. In children with unilateral hydronephrosis, mercaptoacetyltriglycine-3 diuretic renography (MAG3 ) is used to calculate differential renal function and to assess drainage. The aim of our study is to examine whether anteroposterior pelvic diameter on renal ultrasound (US) scan can predict both differential renal function (DFR) and obstruction in pediatric patients, and whether an US adequately identifies those patients who need further investigation...

INTRODUCTION AND OBJECTIVES: Vesicoureteral reflux (VUR) has been one of the defining conditions unique to pediatric urology since its inception. The clinical implications of this disease process depend on intrinsic patient factors such as age, genetics, epigenetics, voiding habits, anatomic anomalies, and extrinsic factors such as the pathogenicity of infectious agents. Knowledge about its natural history, the implications of conservative and surgical management, and their associated outcomes have evolved dramatically over time...

INTRODUCTION: Open ureteral reimplantation (UR) is the gold standard for the surgical management of vesicoureteral reflux (VUR). There have been increasing reports on robot-assisted UR, but this approach remains controversial due to reports suggesting increased complications and reduced success compared with open repair. This study presented extensive experience with vesicoscopic ureteral reimplantation (VR) for primary reflux. In this procedure, cross-trigonal reimplantation was performed in a manner analogous to open repair under carbon dioxide 'pneumovesicum'...

Background: The pathogenesis of renal scarring (RS) after first febrile urinary tract infection (UTI) in children is multifactorial. In addition to well-known risk factors, a role for genetic predisposition has been suggested. Aims: To determine whether deoxyribonucleic acid (DNA) polymorphisms at the plasminogen activator inhibitor -1 (PAI-1) gene were associated with evolution to RS following a febrile UTI in infants. Materials and Methods: Our research included 100 infants, 84 girls and 16 boys, ages up to 1 year with a first febrile UTI, increased inflammatory parameters and positive urine culture treated at the Pediatric Clinic II of the University Clinical Center Sarajevo (UCCS)...

OBJECTIVE: Voiding cystourethrography (VCUG) has been considered as the gold standard technique for the diagnosis of vesicoureteral reflux (VUR). But, it requires fluoroscopic guidance which expose children to radiation. Voiding urosonography (VUS) is technically analogous to VCUG and has the major advantage of zero radiation exposure. This study aims to determine the efficacy of contrast enhanced-VUS (ce-VUS) with respect to VCUG in diagnosing VUR. MATERIAL AND METHODS: This study involves 30 children over a period of 3 years...

Introduction: Vesicoureteral reflux (VUR) is one of the most common ailments in children. Evidence-based guidelines recommend conservative treatment in children with VUR, followed by endoscopic surgery in those with breakthrough febrile urinary tract infections (UTIs). Despite this fact, the management of VUR is still controversial. Our objective is to evaluate the conservative strategy in children with primary VUR in terms of renal function and scarring, and identify factors associated with poor prognosis in those children...

In infants and young children with suspicion of genitourinary tract anomalies, ultrasonography (USG) is usually the first imaging modality. Advantages of USG are well described. In the evaluation of complex congenital urogenital anomalies, ultrasound examination needs to be tailored according to the clinical suspicion and to yield maximum information. Primary megaureter is a congenital anomaly, which is associated with dilatation of ureter above an adynamic segment at the vesicoureteric junction (VUJ). Two different types are described in the literature: refluxing and obstructive...

Background: Vesicoureteric reflux (VUR) is one of the most common anomalies encountered in pediatric urology. The concept of renal functional reserve (RFR) as the ability of the kidney to increase glomerular filtration rate (GFR) following a protein load was introduced in the 1980s. Aim: This study aims to evaluate RFR using 99 Tc diethylenetriamine pentaacetic acid (DTPA) as the filtration agent for GFR estimation in children with VUR. Materials and Methods: RFR was estimated in 53 children, of which 31 patients had unilateral VUR (Group I) and 22 patients had bilateral VUR (Group II), by subtracting baseline GFR from stimulated GFR following an intravenous protein load...

We report a female patient diagnosed with retrocaval ureter (RCU) after ureteral reimplantation for vesicoureteral reflux (VUR). She was diagnosed as right grade IV VUR with breakthrough urinary tract infections, and underwent ureteral reimplantation with Cohen cross-trigonal technique. Thereafter, she developed severe right hydronephrosis associated with RCU, which was presumably due to caudal traction of right ureter at ureteral reimplantation. Sheunderwent uretero-ureterostomy anterior to the inferior vena cava, and recovered well...

BACKGROUND AND AIM: The sacral ratio (SR) is a well-established tool to quantify sacral development in patients with anorectal malformations (ARM) and can be used as a predictor of fecal continence. We hypothesized that a lower SR correlated with the presence of urologic and renal malformations. METHODS: We retrospectively reviewed the medical records of patients with ARM treated at our center from 2014 to 2016. We measured the lateral SR as a marker for sacral development and assessed the spine for the presence of tethered cord (TC)...

Subureteral endoscopic injection is a safe and effective treatment for vesicoureteral reflux (VUR). Dextranomer/hyaluronic acid (Dx/HA) is the most commonly used bulking agent for the treatment of VUR. We report a confusing radiographic finding of calcified Dx/HA injection initially simulates distal ureteral stone in a female patient who has intermittent lumbar pain. Calcification of Dx/HA implants may mimic distal ureteral calculi; therefore, urologists should be aware of the potentially confusing radiographic images...
