The ectopy of the ureter orifices and ureterocele are always followed by either mechanical or dynamic obstruction of the ureter and obstructive pyelonephritis. These anomalies are periodically accompanied by abdominal pains which make their appearance during an attack of acute pyelonephritis. These abdominal pains can be erroneously taken for symptoms of appendicitis or intestinal obstruction and the patients are subjected to appendectomy or laparotomy by mistake. The erroneous appendectomy or laparotomy were fulfilled in 47 of 201 patients with ectopy of ureter orifices and ectopic ureterocele which were observed by the authors. The differentiation of genesis of abdominal pains may be more exact with the help of chromocystoscopy, excretory urography and isotopic renography.

Ultrasound scans were performed on 6 adult males with simple ureteroceles, 2 of which were detected on primary scanning of patients in renal failure and 4 after excretory urography. Two complications were also detected--obstruction with hydro-ureter formation and tumour formation in a ureterocele. A scheme is proposed for differentiating ureteroceles from other causes of bladder filling defects using ultrasound examination.

The authors report their experience on the surgical treatment of 69 infants and children with pyelo-ureteral duplication. Urinary infection was the main revealing symptom (52 cases). Vesico-ureteral reflux was the major associated anomaly (39 cases) involving most often the lower pole ureter; the surgical correction of the reflux was performed according to the technique of Cohen with a favorable outcome in all cases. Because of poorly functioning and dysplastic upper renal segment, partial upper pole nephrectomy was performed in 8 among 12 cases of associated ectopic ureteral orifice and in 9 among 15 cases of associated ureterocele. A reimplantation of the ureter was made possible in 3 cases of ectopic ureteral orifice and in 5 cases of ureterocele with little corresponding renal lesions. With the experience of one neonate who died from septic shock following partial nephrectomy there were no other post-operative complications in this series.

The clinical and pathological findings in 150 children submitted to partial or total nephrectomy have been reviewed. Histological examination of the kidney removed at operation showed evidence of renal dysplasia in 76 (51%). These 76 patients were divided into three main groups on the basis of the pathological changes found in the kidney and the associated urinary tract anomalies. In group 1, gross cystic renal dysplasia was associated with absence or atresia of the renal pelvis and ureter. In group 2, renal dysplasia was segmental; the ureter, although patent, had some anatomical or functional abnormality which resulted in urinary stasis or reflux. In many of these patients dysplasia was confined to the upper pole of a ;duplex' kidney which was drained by an ectopic ureterocele. In group 3, renal dysplasia was associated with obstruction of the lower urinary tract, most commonly by posterior urethral valves. In group 1 dysplasia was total, involving the whole kidney, whilst in groups 2 and 3 dysplasia tended to be segmental; in the majority some normal renal tissue was present. Pyelonephritis was a very common complication, but was present only in patients from groups 2 and 3, in whom a lumen was present in the draining ureter, and not in patients from group 1 in whom the ureter was atretic or absent, and the kidney not functioning. It appears that urinary obstruction, stasis, or reflux are the principal factors predisposing to and promoting pyelonephritis in dysplastic kidneys. There seems to be no reason to suppose that dysplastic renal tissue is abnormally susceptible to infection since pyelonephritic changes were lacking in those cases in which dysplasia was most severe.

During the years 1976-1981, 12 children with duplex kidneys and ectopic ureterocele were operated upon with heminephrectomy and ureterectomy only. This simple procedure led to cure in 10 out of 12 patients. In two of the patients it later had to be supplemented by resection of the ureterocele and reimplantation of the orthotopic ureter. Such a two-stage procedure does not seem to jeopardize the final result.

A case of ectopic ureterocele in a 50-year-old male is reported. He was admitted to the hospital with complaints of miction pain, cloudy urine and fever attack. He had had pain at voiding from time to time during the past 10 years. The prostata was swollen, edematous and tender. Cystoscopy revealed a large bulge in the left trigone to bladder neck, and two ureteral orifices in the right, but none in the left. Complete duplication of the right ureter, lateral deviation of left ureter, and bladder deviation to the right were detected on the drip infusion pyelogram. An ectopic ureteral opening was present in the posterior urethra. A 5 Fr ureteral catheter inserted into this orifice revealed a dilated & tortuous left ureter which belonged to the left upper half kidney. No communication between the ureter & seminal vesicle was revealed by seminal vesiculography. Ureterectomy from left upper half kidney and resection of ureterocele were performed together with ureterovesicoanastomosis to drain urine from the left lower half of kidney.

A case of ectopic ureterocele is reported. A 2-year-old girl was admitted for recurrent episode of urinary tract infection associated with fever. IVP showed bilateral duplex kidney, although no excretion of dye was noted from the right upper kidney. IVP also revealed a large filling defect at the bladder neck which was diagnosed as ureterocele by cystoscopy. Cystography demonstrated VUR to the right lower kidney. A complete duplication of ureter with ectopic ureterocele on the right, and incomplete duplication of ureter on the left were found at operation. She underwent complete removal of the ectopic ureterocele and reimplantation of the right two ureters. Her postoperative course was uneventful, post-operative IVP revealed improvement of pyelography of the right lower kidney and cystography revealed no VUR.

The development of colon carcinoma after ureterosigmoidostomy has not received adequate attention in the radiologic literature. Two patients who had ureterosigmoidostomy and subsequently developed tumors are described. The third case is a patient with a ureterosigmoidostomy and a ureterocele that simulated the appearance of carcinoma in the sigmoid colon. This is the first report of this entity. Ureterosigmoidostomy patients need frequent follow-up studies since their incidence of carcinoma is significant. The use of barium to study the colon in this group of patients is controversial. Barium can potentially reflux into the kidney with fecal material, which can lead to fibrosis and impaired renal function. However, barium reflux up the ureter is usually of no significance except on those rare occasions when intrarenal reflux occurs and inflammatory changes may develop. The diagnosis of tumors in these patients, diagnostic pitfalls, and controversy regarding use of barium enemas in following these patients are discussed.

In conclusion, the diagnosis and management of the ureterocele, simple or ectopic, require careful and thorough preoperative evaluation, culminating in a carefully planned and precisely done operative procedure. An error of omission can be a catastrophe. The choice of surgical approach is controversial but should be one with few potential complications. An awareness and understanding of the potential complications of ureterocele surgery are mandatory and should aid in their prevention. To avoid postoperative complications related to the retained ureteral stump, for ectopic ureteroceles I prefer removal of the entire dilated upper-pole ureter and ureterocele regardless of the manner in which the upper-pole parenchyma is managed. As noted, infants and small children with large ectopic ureteroceles may be approached entirely extravesically, excising the dilated ectopic ureter to the detrusor hiatus.
