A simple orthotopic ureterocele is a ureterocele developed on the terminal portion of a single ureter normally implanted into the bladder. This type of ureterocele is often bilateral and is less frequently observed in children than heterotopic ureteroceles complicating total duplication (27%-73%). The authors report six such cases, review their classical radiological signs, and emphasize three unusual findings:--A simple orthotopic ureterocele complicated by the presence of stones. --A prolapse of a ureterocele into the posterior urethra in a boy, with subsequent dysuria. --A simple orthotopic ureterocele in a blind ureter from a polycystic kidney, with a contralateral primary obstructive mega-ureter.

The most common clinical presentation of ureterocele is infection of the urinary tract. Much less common is obstruction of the bladder outlet by prolapse of the ureterocele into the urethra. Even less common is simple occlusion of the bladder outlet by a nonprolapsing ureterocele. We present such a case where a large, simple ureterocele in a young male led to such obstruction.

A ureterocele may prolapse through the external urethral meatus and present as an interlabial mass. We report a case of a prolapsing ureterocele measuring 10 cm in diameter.

Ureterocele prolapse is a rare presentation of single system ureteroceles and is usually found early in childhood. We present a rare case of recurrent prolapse of a single system ureterocele that did not present until the patient was 17 years of age.

Prolapse of a ureterocele through the external meatus is uncommon, and a prolapsed ureterocele occurring after upper pole heminephrectomy is extremely rare. We describe such a case, occurring 2 months after surgery. The ureterocele was excised with the upper pole ureteral stump, and the lower pole ureter was reimplanted with a good outcome.

Ureterocele is a cystic dilatation of the intravesical ureter that is most commonly observed in females and children, and usually affects the upper moiety of a complete pyeloureteral duplication. According to their position, ureteroceles are divided into intravesical, when the ureterocele is completely contained inside the bladder, and extravesical when part of the cyst extends to the urethra or bladder neck. Most ureteroceles are diagnosed in utero or immediately after birth during an echographic screening of renal malformations. Severe, febrile urinary tract infection is the most common postnatal presentation of ureteroceles, but they may, rarely, prolapse and acutely obstruct the bladder outlet. Once an ureterocele is identified sonographically, a voiding cystourethrogram to detect vesicoureteral reflux (VUR) and a 99m-technetium dimercapto-succinic acid renal scan to evaluate the function of the different portions of the kidney are mandatory. VUR in the lower pole is observed in 50% of cases and in the contralateral kidney in 25%. Simple endoscopic puncture of the ureterocele has recently been advocated as an emergency therapy for infected or obstructing ureteroceles and as an elective therapy for intravesical ureteroceles. The rate of additional surgery after elective endoscopic puncture of an orthotopic ureterocele ranges from 7 to 23%. Treatment of ectopic ureteroceles is more challenging and both endoscopic puncture and upper pole partial nephrectomy frequently require additional surgery at the bladder level. The reoperation rate after endoscopic treatment varies from 48 to 100%. It is 15 to 20% after upper pole partial nephrectomy if VUR was absent before the operation, but is as high as 50-100% when VUR was present. Thus, endoscopic incision is appropriate as an emergency treatment or when dealing with a completely intravesical ureterocele. Upper pole partial nephrectomy is the elective treatment for an ectopic ureterocele without preoperative VUR. In an ectopic ureterocele with VUR, no matter which type of primary therapy has been chosen, a secondary procedure at the bladder level, involving ureterocele removal and reimplantation of the ureter(s), should be anticipated.

A 48-year-old woman presented with a large vulval mass after prolapse of a ureterocele. Her past excretory urogram showed a filling defect (cobra head appearance) in the bladder related to a single-system ureterocele on the left. The mass was manually reduced back through to the urethra under sedation and a urethral catheter was inserted. The anterior wall of the ureterocele was resected transurethrally for definitive treatment.

Prolapse of the ureterocele and its presentation as a vulval mass is an extremely rare condition. There are no detailed imaging findings of such cases in the literature. We present voiding cystourethrography and MRI findings of a newborn girl with a ureterocele extending through the urethra.

We report a case of prolapse of a simple ureterocele presenting as perineural tumor. A 60-year-old woman presented with perineum pain and bleeding. A physical examination revealed a hard mass, 30 mm in diameter protruding from the external meatus. The computerized tomography, magnetic resonance imaging and cystography showed an uncharacterized tumor. Endoscopic examination was performed. However, just before resection the mass collapsed spontaneously and turned out to be a prolapse of ureterocele. No transurethral incision was performed. Eleven months postoperatively, the patient has not developed vesicoureteral reflux or urinary tract infection. Physicians should consider prolapse of a simple ureterocele in the differential diagnosis of the female meatal tumor.
