Modified staged repair of bladder exstrophy: a strategy to prevent penile ischemia while maintaining advantage of the complete primary repair of bladder exstrophy.

J Pediatr Urol 2018 Sep 25. Epub 2018 Sep 25.

Division of Urology, Department of Surgery, Sidra Medical and Research Center, Doha, Qatar. Electronic address:

Introduction: Penile ischemic injury is a reported catastrophic complication after complete primary repair of exstrophy (CPRE). Aiming to improve the bladder exstrophy-epispadias repair outcomes, the study institution adopted a modified staged exstrophy repair to incorporate the advantages of CPRE by avoiding concurrent epispadias repair and adding bilateral ureteral re-implantation and bladder neck tailoring (staged repair of bladder exstrophy with bilateral ureteral re-implantation [SRBE-BUR]) at the initial repair. It was hypothesized that such modifications minimize penile complications and prevent upper tract deterioration while enhancing bladder resistance and consequent capacity. Read More

Urology Mythbusters: should hydronephrosis grade be used to decide which newborns should undergo voiding cystourethrogram?

J Pediatr Urol 2018 Oct 14. Epub 2018 Oct 14.

Boston Children's Hospital and Harvard Medical School, Boston MA United States. Electronic address:

In this episode of Mythbusters the premise that among infants with prenatally identified urinary tract dilation (UTD), voiding cystourethrogram (VCUG) should be performed in those with higher grade UTD but not in those with lower grade UTD is critically examined. It is concluded that severity of dilation is not strongly associated with risk of vesicoureteral reflux or other anomalies diagnosed by VCUG. Therefore, using hydronephrosis grade to decide which infants with UTD should undergo VCUG is not evidence based. Read More

Ultrasound and color Doppler applications in chronic kidney disease.

J Nephrol 2018 Dec 6;31(6):863-879. Epub 2018 Sep 6.

Sant'Anna School of Advanced Studies, Department of Internal Medicine, University of Pisa, Pisa, Italy.

Chronic kidney disease (CKD) includes all clinical features and complications during the progression of various kidney conditions towards end-stage renal disease (ESRD). These conditions include immune and inflammatory disease such as: primary and hepatitis C virus (HCV)-related glomerulonephritis; infectious disease such as pyelonephritis with or without reflux and tuberculosis; vascular disease such as chronic ischemic nephropathy; hereditary and congenital disease such as polycystic disease and congenital cystic dysplasia; metabolic disease including diabetes and hyperuricemia; and systemic disease (collagen disease, vasculitis, myeloma). During the progression of CKD, ultrasound imaging and color Doppler imaging (US-CDI) can differentiate the etiology of the renal damage in only 50-70% of cases. Read More
