[Recurrence of vesicoureteral reflux detected 19 years after ureterocystoneostomy: a case report].

A 21-year-old male, who had been operated on for bilateral vesicoureteral refluxes (VURs) with bilateral ureterocystoneostomy (Politano-Leadbetter's method) 19 years before, was admitted to our hospital due to recurrent VUR. Since the former operation, he had undergone voiding cystography (VCUG) twice for two years, and no refluxes were found. Moreover, no evidence of upper urinary tract deterioration was found by either intravenous pyelography (IVP) or renal ultrasound scanning taken the year before this admission. Nineteen years after the operation, the dilation of the left lower ureter was found on IVP and, consequently, he suffered from pyelonephritis. The VCUG revealed the recurrence of left VUR. Because of his allergic reaction to collagen, we again performed left ureterocystoneostomy (Politano-Leadbetter's method). At three months postoperatively, there was no VUR found on VCUG.
