1/150. 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.

2/150. Acute retention of urine due to prolapsed ectopic ureterocele in an adult male. A case is presented of prolapsed ectopic ureterocele which produced severe urinary retention in a 31-year-old male patient. The usefulness of lumbar transcutaneous puncture is emphasized in a case associated with a non-functioning upper pole of a duplex kidney. ( info) |
3/150. 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. ( info) |
4/150. Common sheath reimplantation with ureteral plication: a useful technique for the management of ectopic ureterocele. BACKGROUND: When salvaging the upper pole kidney in duplex ectopic ureterocele, primary bladder level surgery with common sheath ureteral reimplantation has the definite advantage of allowing the reconstruction of the entire collecting system through a single lower abdominal incision. However, there are several complications associated with a common sheath reimplantation in a child with a very dilated upper pole ureter, such as vesicoureteral reflux or ureterovesical stenosis. methods/RESULTS: To avoid these complications, ureteral plication over the common ureteral sheath in two children with duplex ectopic ureterocele was used. Postoperatively, neither child showed reflux or recurrent urinary tract infection and both showed a marked improvement of the upper pole collecting system. CONCLUSION: This technique allows for a simple and definitive reconstruction in cases of duplex ectopic ureterocele, particularly with dilated upper pole ureter. ( info) |
5/150. ureterocele arising from a lower-pole moiety. We report on an uncommon case of a ureterocele arising from the lower-pole ureter in a duplex system. To our knowledge, this represents the 3rd such case reported in the English literature. ultrasonography and retrograde pyelogram established the diagnosis. The patient underwent left upper-pole nephroureterectomy with excision of the ureterocele and cross-trigonal ureteral reimplantation. ( info) |
| A 1-month-old boy was referred to our hospital with right hydronephrosis. Excretory urography showed poor visualization of the right kidney and a filling defect in the bladder. Chromosomal analysis of peripheral blood revealed a karyotype of 49,XXXXY, and a diagnosis of 49,XXXXY Klinefelter s syndrome associated with hydronephrosis caused by intravesical ureterocele was made. 49,XXXXY Klinefelter s syndrome with anomalies of the urinary tract is extremely rare, and only 2 cases have been reported so far.

7/150. Familial ureteral duplication and ureterocele: two sisters and their father. We studied a family in which the father and his two daughters had ureteroceles involving the upper half of a duplex system. Our report gives additional evidence for the genetic background of ureteroceles. ( info) |
8/150. Evaluation of ureterocele with Doppler sonography. ureterocele is a common disorder characterized by cystic dilatation of the terminal submucosal portion of 1 or both ureters. Conventional imaging modalities for the diagnosis of ureterocele include intravenous urography and voiding cystourethrography; gray-scale sonography, augmented by color Doppler and spectral analysis studies, can be useful in diagnosing and managing this condition as well. We describe the diagnosis of ureterocele using transvaginal gray-scale and color Doppler sonography with spectral analysis in 2 women. color Doppler sonography demonstrated urine flow into the bladder, and spectral analysis was used to measure the flow velocity. Together, these modalities can provide additional information about urinary flow dynamics, aid in implementing treatment for patients with ureterocele, and eliminate the need for invasive diagnostic procedures.

9/150. diagnosis and management of incidental ureterocele during the treatment of clinically localized prostate cancer. Two instances of simultaneous diagnosis of prostate cancer and ureterocele were recently identified. In one patient an ectopic ureterocele in a duplex system with an obstructed upper pole was unroofed at the time of radical prostatectomy. Surgical excision of the ureterocele wall provided decompression of the obstructed system. In a second patient, bilateral intravesical ureteroceles associated with normal renal units were left untreated. Complications were not associated with the untreated ureteroceles. On rare occasions a ureterocele may be discovered incidentally during the evaluation of patients with prostate cancer. When radical prostatectomy is planned, treatment of the ureteroceles should be determined by the ureterocele's size, anatomic configuration, and location and by the degree of obstruction of the affected renal unit. Surgical excision of the ureterocele at the time of radical prostatectomy may be the best approach for patients requiring treatment. ( info) |
| 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. ( info) |
