An ectopic ureterocele is a congenital ballooning of the submucosal part of an extopic ureter in the bladder. It is a relatively common anomaly, usually presenting in childhood. The anatomy, functional pathology, and the clinical symptoms of this disease are described. The authors present a series of 15 cases seen over a 4-year period, 3 patients being adults. Diagnostic and therapeutic problems of this anomaly are discussed in the light of the reported cases.

22 of 114 infants with prenatal diagnosis of urinary tract malformations (15 boys) had obstruction of the ureterovesical junction caused by primary megaureter (n = 14), ureterocele (n = 7), or ectopic ureter (n = 1). Infants with infravesical obstruction or refluxing systems were excluded. All infants had a normal renal function and probably only 5 of them (23%) would have been diagnosed during infancy without prenatal diagnosis. A total number of 26 renal units was evaluated. Six infants had ipsilateral duplication with additional contralateral duplication (n = 2) or vesicoureteric reflux (n = 2). A nonfunctioning kidney or upper pole of duplication was noted in 7 units (5 with ureteroceles); in two instances a moderately dysplastic kidney was present. One boy with urinary infections developed renal scarring during follow-up. Conservative treatment was performed in 14 renal units while 12 units of 11 children had 22 operations (9 temporary diversions) at a mean age of 4,6 months. A severe operative complication was noted in one infant. Conservative treatment is justified in many infants with primary obstructive megaureters but severe renal dysplasia may be present even neonatally. Yet we feel that prenatal diagnosis benefitted most infants, especially those with the most severe malformations.

A 29 year-old male with the complaints of two steps urination and sense of residual urine was admitted. At cystoscopy, a ureterocele was found between the normal left ureteric orifice and the bladder neck. Excretory urography demonstrated a radiolucent area in the bladder and a left lower hydroureter. Retrograde pyelography revealed that the left ureter was divided into two branches. Operative exploration demonstrated that the left ureter was an inverted Y ureteral duplication with an ectopic ureterocele; one opened into the ureterocele and the other into the trigone. We resected the ureterocele wall. Four months later, a voiding cystogram did not show vesicoureteric reflux. Now, he has no symptoms and the results of examination are normal. An inverted Y ureteral duplication is the rarest of all anomalies of the ureter. A review of the literature revealed 36 cases reported previously. Clinical analysis was obtained by reviewing 26 of these cases and adding our own (male 10: female 17, average age: 23 years). Complication included 6 cases of ectopic ureteral opening, 6 with blind-ending branch and 5 with ureterocele. The symptoms of this disease depended on the complicating anomalies. The present case was the 5th one of an inverted Y ureteral duplication with a ureterocele in the world literature.

Four types of ureteroceles are described: A) ureterocele with single ureter (10%); B) ureterocele with total duplication and intra-vesical development (10%); C) ureterocele with total duplication and extra-vesical development (62%); D) ureterocele with ectopic ureter (3%). Most ureteroceles are now detected by antenatal ultrasonography, allowing early management. The treatment of types A and B is simple depending on the status of the above kidney and ureter: abstention, meatomy, ureterocelectomy with ureteral reimplantation, nephrectomy. In type C, the upper kidney is always destroyed. Two treatments are proposed: upper pole nephrectomy with ureterocelectomy which is a difficult but safe procedure, upper pole nephrectomy with aspiration of the ureterocele which is called the "simplified technique" but requires reoperation in 40% cases. The complicated forms may require either meatotomy for decompression, or diversion by percutaneous nephrostomy. Strangulation of the ureterocele constitutes an emergency.

Ten cases of duplex kidney with ectopic ureterocele were detected by ultrasound in the recent four years. There were eight girls and two boys. One case was found to have bilateral ectopic ureterocele, the others were unilateral. Urinary tract infection was found in five cases, urinary dribbling was told in one case, and the other four cases were asymptomatic. The age distribution ranged from newborn to 15 years. Six cases received surgery, and the other four cases were followup at O.P.D. In these cases, the sonography could identify the hydronephrotic nature of the upper pole moiety. Dilatation of the upper pole ureter could be demonstrated. A sonolucent intravesical cystic mass also could be outlined. In this series, five cases with residual parenchyma were assessed by ultrasonography, and two cases with pus formation in the upper pole collecting system were detected. On intravenous urogram, the affected upper pole moiety was not or poorly visualized in these cases, thus produced some diagnostic challenges. Ultrasonic examination is an excellent method to identify a fluid-filled cystic structure, and can provide a simple and non-invasive technique for confirmation of ectopic ureterocele, which is independent of renal function. Therefore, it has become an important modality in the detection, diagnosis and followup of this anomaly.

We retrospectively analyzed pre- and postoperative sonographic and medical records of 335 children who had surgical or endoscopic treatment at the ureterovesical junction, in order to determine normal and atypical sonographic appearances. Normal sonographic findings after ureteral reimplantation include thickening of the posterior bladder wall, pseudodiverticular sacculations, bladder asymmetry, and transitory hydroureteronephrosis. Short-term or persistent (lasting more than 1 month) hydroureteronephrosis, urinoma, hematoma, bladder lithiasis, and diverticula were abnormal findings, occurring in 17% of the patients. After partial ureteronephrectomies, visualization of the residual ureter on sonograms was not possible in cases without complications; in one patient, reflux of fluid dilated the residual ureter and made the ureter visible on sonograms. After endoscopic incisions, the masslike appearance of a collapsed ureterocele was observed. Submucosally injected Teflon always appeared as a curvilinear hyperechoic area with an acoustic shadow. Marked acute or persistent hydroureteronephrosis or ectopic intracavitary Teflon particles were observed in 2% of patients. Granuloma formation was considered likely in 5% of the patients when the area of injected Teflon material was longer than 12 mm on sonograms. Submucosally injected collagen appeared less echogenic than Teflon and showed no acoustic shadowing. The various normal sonographic appearances after treatment must be known in order to distinguish them from significant abnormalities. In patients with anatomic anomalies, such as short-term or persistent hydroureteronephrosis, urinoma, hematoma, and lithiasis, complementary uroradiologic examinations may be necessary to clarify the diagnosis.

Ureterocele is a congenital urinary abnormality characterized by the presence of an intrabladder hernia or cystic ballooning of the lower end of an ureter lying between the mucosa and muscle of the bladder. The abnormality leads to urinary retention and recurrent urinary tract infection which can cause irreversible damage to the kidney. It can become very large and is the most common cause of bladder outlet obstructions in infant girls. It may be associated with serious urologic abnormalities in either sex. This abnormality can be suspected in the fetus by ante-natal echography and confirmed by other X-ray investigations after birth.

We reviewed the cases of 95 children with duplex ureteroceles treated in this department over an 18-year period. There were 101 ureteroceles (6 bilateral). Diagnosis and treatment were analyzed. Special attention was paid to newborns screened in utero. We always strove to preserve functional renal tissue whenever possible. In keeping with this goal, three surgical techniques were used: (1) upper pole heminephrectomy; (2) ureterocele excision, bladder neck reconstruction, and ureter reimplantation with or without cutaneous ureterostomy of the upper pole ureter; and (3) endoscopic ureterocele incision. Follow-up studies using x-ray and radionuclide imaging demonstrated satisfactory renal function in 86.6% of patients. These findings support a conservative approach to ureteroceles using endoscopic ureterocele incision as the primary treatment. Lower urinary tract reconstruction may be associated in cases involving urinary tract infection, obstruction or incontinence. Upper pole heminephrectomy should be performed only after functional evaluation following ureterocele incision or cutaneous ureterostomy.

In three patients (mean age about 3 years) we established excretory tract duplication with obstructed ectopic ureter, a function of the upper pole and ectopic ureterocele. Diagnostic procedure was different in each case. Ultrasonography was the most important diagnostic method in all cases; it usually showed all main morphological details, regardless of functional ability of the kidney. To complete diagnosis, we used additional methods: antegrade pyelography and percutaneous nephrotomy. Excretory urography and voiding cystography gave only indirect signs of a functional part of duplicated excretory tract. The methods we used were complementary and they should rationally be combined in order to complete the diagnosis of ureteral duplication with complications.
