Vesicoureteral reflux after ureteroneocystostomy: indications for postoperative voiding cystography.

摘要: PURPOSE The aim of this study was to determine the risk factors for vesicoureteral reflux following ureteral reimplantation identify a population that can be safely excluded from postoperative voiding cystography. MATERIALS AND METHODS We retrospectively reviewed medical records 273 patients who underwent ureteroneocystostomy between 1990 and 1998 recorded renal ultrasonography cystography results. RESULTS There were (534 ureters) reimplantation. grade preoperative hydronephrosis noted several intraoperative variables, such as dysfunctional voiding, breakthrough infections, scarring, bladder trabeculations, type reimplant, urinary tract infections. With mean follow-up 20.6 months, persistent in 11 (4%). Persistent (4%) or 12 units (2.2%). Reflux resolution rates 534 after routine cystourethrogram (VCUG) 97.8% (renal units) 96% (patients), respectively. Contralateral developed 4 (5.1%) 78 unilateral Two (0.7%) had obstruction. identified hydronephrosis, tapered reimplantations. reimplant did not correlate with outcome. CONCLUSIONS Vesicoureteral is uncommon Because high success rate reimplants benign course those low-grade reflux, it safe efficient eliminate VCUG most simple reflux. However, some higher-risk patients, tapering, may indicated assure
