Robot-assisted laparoscopic ureterolysis: case report and literature review of the minimally invasive surgical approach

To evaluate our case of robot-assisted ureterolysis (RU), describe our surgical technique, and review the literature on minimally invasive ureterolysis. One patient managed with robot-assisted ureterolysis for idiopathic retroperitoneal fibrosis was identified. The chart was analyzed for demographics, operative parameters, and immediate postoperative outcome. The surgical technique was assessed and modified. Lastly, a review of the published literature on ureterolysis managed with minimally invasive surgery was performed. One patient underwent robot-assisted ureterolysis at our institution in 2 separate settings. Operative time (OR) decreased from 279 minutes to 191 minutes. Estimated blood loss (EBL) was less than 50 mL. The patient has been free of symptoms and both renal units are unobstructed. According to the published literature, 302 renal units underwent successful laparoscopic ureterolysis (LU), and 6 renal units underwent RU. There were 9 open conversions (all in LU). Mean OR in LU was 248 minutes for unilateral and 386 minutes for bilateral cases. In RU, mean OR was 220 minutes for unilateral and 390 minutes for bilateral cases. EBL averaged 200 mL in LU and 30 mL in RU. Our data reveal that robot-assisted ureterolysis is safe and feasible. Published data demonstrate the advantages of minimally invasive surgery.
