The Dilemma of Ureterovesical Junction Obstruction
Nephro-urology monthly(2017)
Abstract
Background: Ureterovesical junction obstruction (UVJO) is the result of an anatomic or a functional abnormality in the distal segment of the ureter. There are many types of UVJO, different in their cause, presentation, imaging characters, and prognosis. Objectives: The aim of this study was to discuss the postoperative natural course and prognosis of patients undergoing standard approaches on the management of primary UVJO by one surgeon in a 10-year period starting from 2004. Methods: From January 2004 to October 2013, 64 patients who underwent ureteral tapering and stenting ureteroneocystostomy for complicated primary UVJO participated in the study. Results: The mean age of patients was 26 years (range: 11 months to 73 years). The mean hospital stay was 5 days (range: 4 to 7 days). The post-operative time was between 1 and 2 hours. Double J stent was left in place for 4 weeks. Post-operative follow-up was at least one year. No major complication was encountered, instead, a decrease in symptoms in all patients and an increase in renal function in 40 out of 64 (62.5%) patients were observed in the one-year follow-up of the diethylenetriaminepentaacetic acid (DTPA) renal scanning. Only 3 patients had fever as a postoperative minor complication. Conclusions: Decision making in the treatment of UVJO is somewhat a dilemma. This condition is occasionally asymptomatic and uneventful, and may be detected accidentally during an unrelated work-up; nonetheless, it may also cause serious life threatening complications. Surgical management in complicated cases may be a safe and viable treatment option both in children and in adults.
