Department of Radiology, Okayama University Hospital, 2-5-1 Shikata-cho, Kita-ku, Okayama, Japan 700-8558.

Percutaneous cryoablation for renal tumors may be associated with rare complications such as injury to the ureter. A 65-year-old woman underwent percutaneous cryoablation after a transcatheter arterial embolization using lipiodol and ethanol for left renal oncocytoma. Two months after the percutaneous cryoablation, computed tomography images showed left hydronephrosis caused by high-density debris, which was assumed to be sloughed tumor with lipiodol accumulation in the left ureter.

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

Retrocaval or circuncaval ureters are rare congenital anomaly, in which the ureter is located posterior to the inferior vena cava (IVC).

Herein we report the case of a 62-year-old patient who underwent ultrasonography to investigate abdominal pain. Read More
