J Coll Physicians Surg Pak 2016 Nov;26(11):926-928

Department of Medicine, Hamad General Hospital, Doha, Qatar.

Two patients with end-stage-renal-disease on continuous ambulatory peritoneal dialysis (CAPD) presented with pleural effusions. The aspirated fluid was categorised as transudate, based on alkaline pH, low protein and lactic dehydrogenase level. A striking feature of the pleural fluid was, its very high glucose content that resulted from translocation of dextrose containing peritoneal dialysate into the pleural space via a pleuroperitoneal connection.

The role of voiding cystourethrography in asymptomatic unilateral isolated ureteropelvic junction obstruction: A retrospective study.

J Pediatr Urol 2017 Apr 24;13(2):206.e1-206.e7. Epub 2016 Nov 24.

Division of Pediatric Urology, Aboul-Riche Children's Hospital, Cairo University, Cairo, Egypt.

Introduction: The presence of concomitant vesicoureteric reflux (VUR) and ureteropelvic junction obstruction (UPJO) is uncommon. Nevertheless, the reported VUR coexisting with asymptomatic unilateral isolated hydronephrosis (AUIH) requiring pyeloplasty for correction of UPJO was of low grade and mostly resolved during conservative follow-up. Therefore, VCUG may be not indicated in these children except if voiding symptoms, urinary tract infection (UTI), dilated ureters, or bladder and ureteric abnormalities are suspected. Read More

The Swedish infant high-grade reflux trial: Study presentation and vesicoureteral reflux outcome.

J Pediatr Urol 2017 Apr 24;13(2):130-138. Epub 2016 Oct 24.

Department of Paediatric Surgery, Paediatric Uronephrologic Centre, Queen Silvia Children's Hospital, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Sweden.

Introduction: High-grade vesicoureteral reflux (VUR) in infants is associated with congenital renal abnormalities, recurrent UTI, and bladder dysfunction. Endoscopic treatment (ET) is a well-established method in children with low to moderate reflux grades, but there is a lack of randomised controlled trials regarding the use of ET versus continuous antibiotic prophylaxis in infants with high-grade VUR.

Objective: This study aimed to determine whether high-grade VUR in infants can be treated with endoscopic injection and whether ET is superior to antibiotic prophylaxis in the treatment of VUR. Read More

Urology 2017 Mar 3;101:85-89. Epub 2016 Oct 3.

Department of Surgery and McMaster Pediatric Surgery Research Collaborative, McMaster University, Ontario, Canada; Clinical Urology Research Enterprise (CURE) Program, McMaster Children's Hospital, Ontario, Canada; Division of Urology, Department of Surgery, McMaster University, Ontario, Canada.

Objective: To explore the potential value of an objective assessment, renal parenchyma to hydronephrosis area ratio (PHAR), as an early predictor of surgery.

Methods: Initial sagittal renal ultrasound (US) images of patients prospectively entered into a prenatal hydronephrosis database from January 2008 to January 2016 with baseline Society for Fetal Urology (SFU) grades III and IV prenatal hydronephrosis, without vesicoureteral reflux, were evaluated using the National Institutes of Health-sponsored image processing software. PHAR, anteroposterior diameter, SFU grade, and urinary tract dilation risk categories were contrasted with nuclear scan data (differential renal function and drainage time [t]) and analyzed for predictive value in determining the decision to proceed with surgery by drawing receiver operating characteristic curves.

Reliability of grading of vesicoureteral reflux and other findings on voiding cystourethrography.

J Pediatr Urol 2017 Apr 6;13(2):192-198. Epub 2016 Sep 6.

Department of Urology, Boston Children's Hospital, Boston, MA, USA.

Introduction: Voiding cystourethrography (VCUG) is the modality of choice to diagnose vesicoureteral reflux (VUR). Although grading of VUR is essential for prognosis and clinical decision-making, the inter-observer reliability for grading has been shown to vary substantially. The Randomized Intervention for Children with VesicoUreteral Reflux (RIVUR) trial provides a large cohort of children with VUR to better understand the reliability of VCUG findings. Read More
