1/867. Unilateral renal agenesis presenting as anuria.

    The most common cause of sudden and total cessation of urine output is obstructive uropathy, usually at the bladder outlet. Bilateral ureteral obstruction is a much less common cause of anuria. In additioh, unilateral obstruction in the presence of a solitary kidney must be considered in the differential diagnosis. Primary renal parenchymal disorders and pre-renal azotemia occasionally may be anuric but more commonly are oliguric. A case of unilateral renal agenesis presenting as anuria and obstruction of the solitary kidney is described.

2/867. Inflammatory abdominal aortic aneurysm and bilateral complete ureteral obstruction: treatment by endovascular graft and bilateral ureteric stenting.

    Inflammatory abdominal aortic aneurysms may present a challenge to the surgeon, especially because of associated retroperitoneal fibrosis and possible ureteral complications. We present a case of inflammatory abdominal aortic aneurysm with bilateral ureteral entrapment and complete anuria, successfully treated by endovascular grafting and temporary ureteral stenting.

3/867. Upper urinary tract obstruction: pressure/flow studies in children.

    34 upper urinary tract pressure/flow studies were carried out in 24 children. Obstruction was reliably diagnosed in 8 studies, and excluded in 21. This technique may provide information of clinical value in the patient with upper urinary tract dilatation.

4/867. Idiopathic cervical and retroperitoneal fibrosis: report of a case treated with steroids.

    retroperitoneal fibrosis in a 12-year-old boy is reported. This was associated with a fibrotic mass in the neck which resolved spontaneously. Right-sided ureteric obstruction responded to treatment with steroids.

5/867. Surgical treatment of reflux in completely duplicated ureters.

    Vesicoureteral reflux occurs in approximately 50% of duplex systems that undergo evaluation and most commonly involves the lower renal segment ureter. The therapeutic approach can be tailored for each case after careful evaluation of the anatomic and functional status of each renal unit. If reparative srugery is indicated and only one ureter is involved, then ureteropyelostomy or ureteroureterostomy have yielded excellent results. If more than one ureter is involved with either relfux or obstruction, then reimplantation of the paired ureters is indicated if the renal units are slavageable.

6/867. Renal aspergillosis giving rise to obstructive uropathy and recurrent anuric renal failure.

    A sixty-year-old previously healthy male patient presented with anuric renal failure of sudden onset. He was detected to have aspergillus fumigatus fungal balls in the renal pelvis, ureters and bladder which were removed and his renal function improved. He was treated with itraconazole and sent home. Three weeks later he again presented with anuria and renal failure. He had recurrence of the obstruction with the same fungus. The fungal ball was removed, a double 'J' stenting was performed and he was treated with amphotericin b and itraconazole. Hence we report a previously healthy patient with no evidence of immunosuppression presenting an obstructive anuric renal failure due to isolated renal aspergillosis.

7/867. Ureteral compromise after laparoscopic Burch colpopexy.

    ureteral obstruction occurred in two patients after laparoscopic Burch cystourethropexy. Both women experienced right flank pain and right hydronephrosis. cystoscopy revealed transmural passage of suture anterior and lateral to the ureteral orifice on the right side. One patient was managed by suprapubic cystoscopy to release the suture; the other was managed by preperitoneal laparoscopy to release suture at the bladder neck. In both patients efflux of urine was seen immediately from the ureteral orifice after suture release. Ultrasound confirmed prompt resolution of hydronephrosis. cystoscopy with confirmation of patent ureters should be performed after every case of retropubic cystourethropexy. Retrograde rigid cystoscopy may not afford adequate access to remove transmural sutures. Placement of sutures at the bladder neck from medial to lateral may avoid entrapment of the intramural portion of ureter. (J Am Assoc Gynecol Laparosc 6(2):217-219, 1999)

8/867. Urinary undiversion for pelvic actinomycosis: a long-term follow up.

    BACKGROUND: A 43-year-old woman who had been using intrauterine contraceptive devices for the past 10 years underwent an emergency operation for bowel and urinary obstruction. methods/RESULTS: Frozen section analysis showed undifferentiated adenocarcinoma. Incomplete tumorectomy, ileal resection, partial cystectomy, colostomy and bilateral ureterocutaneostomy were palliatively performed. Postoperatively, periodic acid-Schiff and Grocott-Gomori methenamine tests revealed actinomyces and the final diagnosis was pelvic actinomycosis. Treatment with penicillin g administered intravenously relieved her symptoms and the lesion was dramatically improved. The patient underwent colostomy closure and urinary undiversion. CONCLUSIONS: Five years after urinary undiversion, the patient's renal function has been maintained and she can void without incontinence and dysuria.

9/867. Management of ureteric obstruction in the solitary kidney by a segmental suspended ureteric prosthesis.

    Ureteric obstruction of a single kidney, secondary to an aorto-iliac bypass graft, was treated with a suspended segmentary ureteric prosthesis. No urinary stasis was observed during 1 year and the urodynamic implication are discussed.

10/867. Acute renal failure due to obstruction in burkitt lymphoma.

    Acute renal failure in burkitt lymphoma is commonly the result of tumor lysis syndrome. We present a 15-year-old boy who developed hypertension, seizures, and acute renal failure due to extrinsic compression of the bladder and ureters by a large retrovesical burkitt lymphoma. The causes of acute renal failure in burkitt lymphoma and the incidence of acute urinary obstruction in this disease are reviewed.
