1/476. Bilateral ureteric replacement with ileum. In connection with a report of a case, authors discuss in outline the possibilities of ureter replacement. If both the ureters are injured, they can be substituted with one single segment of the intestine, as it happened in their case. Authors raise the idea that a longer segment of the intestine used for substitution provides sufficient capacity and isoperistaltic function, and this may protect from the negative effects of possible vesicoileal reflux. In this case, the reflux does not spread to the kidneys even if the ureteroileal was not made with anti-reflux technique. ( info) |
2/476. 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.

4/476. 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) |
5/476. Asymptomatic ureteral varices: detection by Doppler sonography. Retroperitoneal ectatic or varicose veins may cause ureteral extrinsic pressure defects. Doppler sonography may be helpful in the characterization of these vascular lesions. We report the sonographic findings in a case of asymptomatic idiopathic left ureteral varices. ( info) |
6/476. Ureterocystoplasty in a patient with a single kidney. Ureterocystoplasty (UCP) has now been widely used for bladder augmentation, with and without unilateral nephrectomy. Many techniques have been described to incorporate portions of the upper renal tract, but none have yet described UCP in a child with unilateral renal agenesis. ( info) |
7/476. Bilateral ureteritis cystica with unilateral ureteropelvic junction obstruction. Ureteritis cystica is a rare, benign, proliferative disorder characterized by multiple ureteral cysts and multiple filling defects noted on contrast ureteral imaging. A unique case of bilateral ureteritis cystica coincidental with chronic, congenital, unilateral ureteropelvic junction obstruction presenting with microscopic hematuria and lower urinary tract symptoms is described. The characteristic presentation as well as the diagnostic radiographic, ureteroscopic, and histologic features of pyeloureteritis cystica are reviewed. ( info) |
8/476. Case report: percutaneous balloon dilatation and ureteral stenting for tuberculous renal infundibular and ureteral strictures. A 23-year-old woman developed progressive obstructive uropathy due to multiple renal infundibular and ureteral strictures while on drug treatment for renal tuberculosis. communication between isolated upper and mid-pole calyces, and the ureter, was established by percutaneous guidewire manipulation. The strictures were successfully managed using percutaneous balloon catheter dilatation and ureteral stenting without the need for open surgical exploration. kidney function was preserved at one year follow-up.

9/476. Laparoscopic repair of ureterosciatic hernia. Ureterosciatic herniation is a rare benign event that can mimic diverticulosis or irritable bowel syndrome. This entity has been managed by a number of open surgical techniques. Laparoscopic repair of this entity enabled us to identify the defect, interpose mesh, and obliterate the hernia defect with minimal morbidity. This represents the first report of laparoscopic repair of a ureterosciatic hernia. ( info) |
10/476. Retroperitoneal paragonimiasis: a case of ectopic paragonimiasis presenting as periureteral masses. We describe a case of retroperitoneal paragonimiasis presenting as periureteral masses. CT showed a conglomerate of enhancing nodules with subtle low attenuation in the center at the left iliac fossa and clustered, ring-like, enhancing lesions at the left renal hilum. When a retroperitoneal conglomerate of ring-like, enhancing lesions in association with pleuropulmonary disease suggestive of paragonimiasis can be found in endemic regions or in migrants from those regions, one may expect ectopic-retroperitoneal paragonimiasis.
