[Cecoureterocele. A case report].

A case of cecoureterocele in a 22-month-old girl is reported. She was admitted because of recurrent urinary tract infection associated with fever and dysuria. Excretory urogram showed a left duplex kidney with hydroureteronephrosis of the upper and lower moieties. Although the left upper moiety was hypofunctioned, some excretion of contrast medium was noted. Voiding cystourethrography demonstrated reflux into the left upper moiety, and a prominent dilation of the bladder neck and the urethra. Bladder sonography demonstrated an ectopic ureterocele at the bladder neck, and it was diagnosed as a cecoureterocele by endoscopic examination. Left pyelopyelostomy, total ureterectomy from the left upper half kidney and open resection of the ureterocele were performed together with reimplantation of the left lower ureter using Cohen technique in 1 stage. At the operation, the left lower ureter was confirmed as a typical obstructive megaureter. Convalescence was uneventful, and postoperative excretory urogram revealed an improvement of the left pyeloureterogram. But the postoperative voiding cystourethrography showed a remnant of cecoureterocele in the urethra causing bladder outlet obstruction. Endoscopic incision of the remnant cele wall in the urethra resulted in marked improvement in voiding and complete resolution of urinary tract infection. A brief review of cecoureterocele was given.
