1/11. Unusual anatomic presentation of ectopic ureteroceles.

    The authors describe four patients with unusual anatomic presentation of ectopic ureteroceles and their surgical treatment. Over a 3-year period, four cases of unusual ectopic ureteroceles were encountered. A 6-month-old girl had a complex cloacal anomaly with an ectopic ureterocele within the cloaca. A 10-year-old boy had two large diverticuli within an ectopic ureterocele combined with a blind-ending ipsilateral ureter. A 3-year-old girl had an ectopic ureterocele combined with a periureteral diverticulum and a completely duplicated ipsilateral kidney. A 4-year-old girl was found to have a vaginal ectopic ureterocele. Despite thorough radiological investigation in all patients, a correct assessment of the anatomic defect was achieved only by surgical exploration or endoscopic evaluation. If preoperative radiological evaluation is equivocal, a high index of suspicion and intraoperative recognition of an unusual anatomic presentation of the ectopic ureterocele are essential for appropriate management and a successful outcome.

2/11. Ultrasonographic demonstration of a simple ureterocele and dilated ureter in an adult.

    A 54 year old man was found to have a simple ureterocele with a dilated ureter. ultrasonography demonstrated the ureterocele as an echo-free structure at the base of the bladder without involvement of the bladder wall. The course of the dilated ureter and its entrance into the bladder were clearly defined.

3/11. Endoscopic management of prolapsing intravesical ureterocele in an adult female--a case report.

    The authors present a case of intravesical ureterocele in a female which prolapsed out of the external urethral meatus causing urinary obstruction, and was managed by reduction into the bladder followed by endoincision.

4/11. Retroperitoneoscopic heminephrectomy of the right upper collecting system emptying into an ectopic ureterocele in a 5-year-old girl: a case report.

    A 5-year-old girl with a history of recurrent urinary tract infection since the age of 14 months was diagnosed as having a right duplicated urinary collecting system with the upper ureter ectopically opening in the urethra. She underwent retroperitoneoscopic heminephrectomy for a right dysplastic kidney and open ureterocelectomy and reimplantation of the refluxing lower ureter via Pfannenstiel incision. She survived the procedure without serious complications and resumed normal daily activities by day 6. To the best of our knowledge, this case is the 16th case of laparoscopic heminephrectomy for pediatric patients and the first case treated by the retroperitoneal approach in the English literature.

5/11. Vaginal metaplasia of the bladder associated with ectopic ureterocele. A clinicopathologic study of two cases.

    We report two cases of vaginal metaplasia associated with ectopic ureterocele with complete ureteric duplication. The theories proposed to explain this metaplastic change are briefly reviewed. This previously unreported association with ectopic ureterocele suggests that this may an example of heteroplasia, and that this relationship could be more than casual.

6/11. Ectopic ureters misdiagnosed as ureterocele.

    Ectopic ureters may be difficult to diagnose unless there is high index of suspicion. Examination for continuous dribbling may be difficult in infants who are still using diapers. We are reporting a case of ectopic ureter which was erroneously diagnosed as ureterocele on a cystourethrogram. Further investigations for accurate diagnosis and emerging abnormalities during the course of management are presented in this case report. review of literature to highlight the various forms of investigations and management are also presented.

7/11. Ultrasonic evaluation of the obstructed duplex kidney.

    The problem of a duplex collecting system associated with an obstructed ectopic ureter or ureterocele is common in pediatric urology. Four such patients were studied by gray scale ultrasound which was useful in demonstrating the dilated upper pole collecting system as well as an ectopic ureter and a ureterocele. Although the diagnosis of a nonfunctioning upper pole unit in a duplex kidney is usually suggested by the urogram, ultrasound provides a noninvasive means of confirmation which is independant of function. Further, ultrasound-guided puncture with antegrade pyelography demonstrates the course of the ectopic ureter, thus providing a more complete preoperative evaluation.

8/11. Ectopic ureterocele, hydroureter, and renal dysplasia: an embryogenic triad.

    A review of the literature of the embryogenesis of ectopic ureterocele is presented. A theory linking the triad of ectopic ureterocele, hydroureter, and renal dysplasia to a primary intrinsic developmental abnormality of size and position of the ureteral bud is postulated.

9/11. Prolapsed single system ureterocele in a girl.

    Ureteroceles in childhood usually are associated with ureteral duplication. A 7-year-old girl with a single system ureterocele is described. The patient presented clinically with urinary infection and prolapse of the ureterocele, causing urinary retention.

10/11. Ipsilateral ureteroureterostomy for single ureteral disease in patients with ureteral duplication: a review of 8 years of experience with 16 patients.

    Ipsilateral ureteroureterostomy near the bladder (end-to-side anastomosis) for treatment of single ureteral disease in patients with complete ureteral duplication has been performed in 16 patients during the last 8 years. The operative technique, indications, results, followup and complications are presented. Reflux in the lower segment ureter was treated in 13 patients and upper segment ectopia or ureterocele was managed in 3 patients with this operative procedure. This operative technique is simpler and safer than reimplantation of both ureters into the bladder. Because no dissection of the bladder wall is needed there is less risk of injury to the pelvic viscera and vasculature. The chance of success in correcting reflux appears better than with reimplantation of both ureters into the bladder. Long-term followup has shown few complications and no repeat operations were needed in this series. The small stump of the diseased ureter left behind near the bladder caused no serious problems.
