    Abstract:
    INTRODUCTION: Idiopathic retroperitoneal fibrosis is a known cause of obstructive uropathy. Ureterolysis is done when medical management fails or the presentation is at an advanced stage. Conventionally ureterolysis without omental wrap has been considered incomplete. Our Institute has experience of laparoscopic or robotic ureterolysis with intraperitonealization of the ureter alone and no other adjunctive procedure. This study retrospectively assesses the result of the procedure with patients presenting with varying severity of disease. METHODS: From 2008, all patients who underwent laparoscopic or robotic ureterolysis were analyzed retrospectively for pre-operative management, operative findings, and post operative outcomes. RESULTS: We operated and released nine renal units in seven patients. Two of the nine cases were performed robotically completely and the rest was performed by laparoscopic approach. Median follow up was 60 months. All patients documented resolution of symptoms. The mean post-operative creatinine at 1 year was significantly decreased to 1.47 ± 0.49 mg/dl in comparison to preoperative creatinine (p < 0.05). The postoperative mean ESR decreased significantly from a preoperative value of 58.2 ± 19.41 mm to 15.8 ± 17.23. The nuclear scan revealed unobstructed drainage and radiological imaging revealed resolution of hydronephrosis and fibrosis in all. The mean GFR on the nuclear scan after 3 and 12 months of surgery was 36.3 ± 4.33 and 40 ± 3.77, respectively. Thus, there was significant increase noted in GFR at 3 and 12 months in comparison to preoperative GFR (p < 0.05). CONCLUSION: Laparoscopic/robotic ureterolysis with intraperitonealization alone is secure and durable procedure for idiopathic retroperitoneal fibrosis needing surgical release.
