RESUMO
We report a case of cecoureterocele with contralateral ureterovesical junction stricture in 1 month-old boy who presented with bilateral hydronephrosis detected by prenatal ultrasonography, Ultrasonography showed bilateral hydronephrosis, left complete duplex system and lect ureterocele. Voiding cystourethrography demonstrated reflux into the left upper moiety through ureterocele with prominent dilatation of the bladder neck and the proximal urethra. Ureteral stricture at right ureterovesical junction was suspected by intraoperative catheterization and retrograde ureteropyelography. Left upper pole nephrectomy with partial ureterectomy, transvesical unroofing of cecoureterocele and bilateral ureteroneocystostomy using Cohen's method were done. Convalescence was unevenful and postoperative voiding cystourethrography revealed no evidence of vesicoureteral reflux, dilated bladder neck or remnant cecoureterocele.
