11/255. ureteral obstruction after kidney transplantation secondary to bone metaplasia.

    We report a case of ureteral obstruction after kidney transplantation caused by localized bone metaplasia in the donor ureter. Surgical treatment consisted of removal of the involved ureteral segment, which was located 3 cm above the bladder and creation of a spatulated end-to-end anastomosis. Although bone metaplasia has been observed in the ureteral wall of some animal species secondary to experimental ischemia and microtrauma, it is exceedingly rare in humans and has never before been documented after kidney transplantation.

12/255. Periureteric fibrosis complicating kidney transplantation.

    Impairment of renal function developed in a kidney transplant recipient three years after the transplant due to ureteric obstruction. At operation this was found to be due to periureteric fibrosis. Ureterolysis was performed with subsequent return of renal function.

13/255. An endourologic approach to complete ureteropelvic junction and ureteral strictures.

    BACKGROUND AND PURPOSE: Complete stricture of the ureteropelvic junction (UPJ), ureter, or both represents a secondary upper tract obstruction and is a challenge for surgical management. The endourologic repair of these complete strictures remains controversial because of the many unsatisfactory results in the literature. The aim of this study was to achieve recanalization of the ureter or the UPJ using endourologic techniques to prove durable success of this technique. patients AND methods: We present data on the 21 patients with complete UPJ or ureteral strictures treated over 5-year period. The length of the obliterated portion of the ureter or UPJ ranged from 0.3 to 1.7 cm. The stricture was at the UPJ level in 12 patients (57%), in the upper ureter in 3, and in the lower ureter in 4. The technique was a combined approach, with antegrade introduction of the guidewire and retrograde cold-knife incision in the majority of the cases. In five cases, the incision was carried out in the reverse direction with a guidewire introduced retrograde up to the stricture level. An originally designed 6F to 7F polyethylene double-J stent with a movable 12F to 16F silicon sheath or percutaneous tube was placed at the completion of the procedure. RESULTS: The follow-up period ranged from 6 to 48 months. Recanalization was achieved in 17 patients (81%), of whom 14 became symptom free. Other surgical outcomes necessitated open surgical intervention (pyeloplasty, nephrectomy) in two patients. One patient developed a clinically significant recurrent urinary tract infection and deterioration of kidney function. Thus, the overall success rate of the endourologic management of the complete UPJ and ureteral strictures was 67% in our series. CONCLUSION: Endourologic management with retrograde or antegrade pyeloureterotomy can be successful in patients with short (up to 1.0-cm) obliterative strictures who are without extensive hydronephrosis and with preserved renal function.

14/255. Left multicystic dysplastic kidney with contralateral ectopic kidney and ureterovesicle junction obstruction.

    multicystic dysplastic kidney (MCDK) represents the most common cause of abdominal mass in the neonatal period. It is usually combined with contralateral genitourinary tract anomaly. Because the multicystic dysplastic kidney is usually dysfunctional, it is important to evaluate and monitor the remaining preserved function of the contralateral kidney regularly. The presence of severe obstructive lesion over contralateral kidney is often life-threatening. Prompt treatment should therefore be given as early as possible to preserve the remaining renal function. We here report one rare case of left MCDK with contralateral ectopic kidney and ureterovesicle junction (UVJ) obstruction. As the best as we know, this report is the first case report of MCDK with contralateral ectopic kidney and UVJ obstruction.

15/255. Nephrogenic adenoma associated with cytomegalovirus infection of the ureter in a renal transplant patient: presentation as ureteral obstruction.

    Nephrogenic adenoma (NA), a rare benign lesion of the urinary tract, is widely accepted to be a metaplastic reaction due to urothelial injury. It mainly occurs in the urinary bladder and rarely in the ureter. Renal transplant recipients are prone to the development of NA. However in those patients, NA was diagnosed exclusively in the bladder. Herein, we present the--to our knowledge--first case of NA involving a transplanted ureter. A 42-year-old female kidney transplant recipient suffered hematuria, oliguria, and acute renal failure and presented with ureteral obstruction and hydronephrosis of the renal transplant. To our surprise, evidence of cytomegalovirus (CMV) infection of the NA was demonstrated using special immunohistochemical staining. The findings in this case raise the possibility that CMV infection, as an irritant of the ureteral epithelium, may be an etiological factor of NA.

16/255. Postural renal transplant obstruction: a case report and review of the literature.

    A 48-year-old woman underwent cadaveric renal transplantation for end-stage renal failure secondary to polycystic kidney disease. Nine months after transplantation, intermittent renal dysfunction and severe graft hydronephrosis developed despite the presence of a ureteric stent. A Tc-99m MAG3 scan performed with the patient standing showed complete transplant obstruction. Rapid tracer clearance with progressive bladder filling was present when the patient was imaged in the supine position. Ureteric obstruction is the most common urologic complication of renal transplantation. However, postural ureteric obstruction has been described only rarely. This case indicates that posture may affect ureteric patency and highlights this potential pitfall in the evaluation of intermittent graft dysfunction by diuretic renography.

17/255. Gastrointestinal actinomycosis: an unusual presentation with obstructive uropathy: report of a case and review of the literature.

    A 55-year-old female patient is described who had recurrent retroperitoneal infections without an apparent focus. After a protracted period of illness the infection proved to be caused by actinomycosis. An unusual feature of the inflammatory process consisted of obstruction of the ureters, ultimately resulting in destruction of the left kidney. hydronephrosis resulting from inflammatory fibrosis has not been reported in the literature before.

18/255. Duplicated collecting system with lower pole ureteropelvic junction obstruction.

    Two examples of the rare case of complete duplicated collecting system with lower pole ureteropelvic junction obstruction are described. Ureteropelvic junction obstruction (UPJO) and duplicated collecting systems seldom occur in combination. Complete duplication of the ureter may be asymptomatic or recognized when complications develop as a result of reflux into the lower pole ureter or obstruction of the upper pole with an ectopic ureterocele. It is difficult to choose an optimal therapy due to the high variability in function, degree of obstruction, damage and potential for regeneration in growing kidneys. The diagnosis and management of UPJO of the lower pole in complete duplicated collecting systems are discussed.

19/255. Outcome of the distal ureteric stump after (hemi)nephrectomy and subtotal ureterectomy for reflux or obstruction.

    OBJECTIVE: To assess the outcome of the distal ureteric stump (DUS) after (hemi)nephrectomy with subtotal ureterectomy. patients AND methods: The records of 89 patients (median age 2.7 years, range 0.25-12) who underwent nephrectomy (24) or heminephrectomy (65) with subtotal ureterectomy between 1982 and 1996 were reviewed retrospectively for symptoms caused by the DUS. The mean follow-up was 9.8 years. nephrectomy was undertaken for a poorly functioning dysplastic (in nine), scarred (in 10) or hydronephrotic (in five) kidney, and heminephrectomy for a poorly functioning upper moiety associated with ectopic ureterocele (in 26) or stenotic hydroureter (in 15), or for a poorly functioning lower moiety associated with reflux (in 24). There were 38 refluxing and 51 non-refluxing ureteric stumps. Two additional patients primarily operated elsewhere were referred with DUS symptoms. RESULTS: Only one patient had a symptomatic DUS, with recurrent haematuria and bacteriuria. The two patients referred from elsewhere presented with febrile UTIs. The first had been left with a long refluxing stump opening ectopically into the urethra, and the second with a long stump which was converted from nonrefluxing to a refluxing stump when he developed dysfunctional voiding. Surgical excision of the distal stump was curative in each case. CONCLUSIONS: The risk of a symptomatic DUS in patients who undergo subtotal ureterectomy in conjunction with (hemi)nephrectomy is very low, with no difference between refluxing and nonrefluxing stumps. Long ureteric stumps and dysfunctional voiding may cause symptoms. Because of the low morbidity associated with a short ureteric stump, we recommend subtotal ureterectomy in children who undergo (hemi)nephrectomy for reflux, vesico-ureteric obstruction or ectopic ureterocele associated with a poorly functioning kidney or kidney moiety.

20/255. Spontaneous peripelvic extravasation secondary to ovarian cyst: a case report.

    We present a case of spontaneous peripelvic extravasation caused by ureteral obstruction secondary to an ovarian cyst. A 47-year-old woman with lower abdominal pain visited our emergency clinic. Emergency computed tomographic scan revealed extravasation around the left kidney and a left ovarian cyst. She was diagnosed to have spontaneous peripelvic extravasation by retrograde pyelography. A double pigtail stent was placed and the ovarian cyst was removed surgically. Intravenous pyelography performed after removal of the stent revealed neither urinary extravasation nor obstruction.
