Pediatric Hospital H. J. Notti, Mendoza, Hospital Italiano, Buenos Aires, Argentina.

Purpose: Recently, the use of ureter for bladder augmentation has gained wide acceptance due to a lower complication rate compared to gastrointestinal segments. Unfortunately, the presence of a severely dilated urinary tract implicates loss of function of a renal unit which is often not demonstrated at diagnosis. Conversely, many patients present with 1 or both ureters mildly dilated because of vesicoureteral reflux or functional obstruction. Read More

Department of Surgery, National University Hospital, Singapore.

The principles of ureteric reconstruction are not different from those of reconstructive urology in the rest of the urinary system. The importance of ensuring good vascular supply, complete excision of pathological lesions, good drainage and a wide spatulated and tension-free anastomosis of mucosa to mucosa remain paramount. Although time of diagnosis is the most single most adverse factor affecting outcome, the majority of ureteric injuries still present postoperatively, and delays in diagnosis are the rule rather than the exception.
