Comparison of Laparoscopic and Open Ureterolysis for Retroperitoneal Fibrosis: Results from a Tertiary Referral Center.

To compare the surgical outcomes of open and laparoscopic ureterolysis procedures in patients requiring surgical treatment for ureteral obstruction caused by retroperitoneal fibrosis (RPF). This study was designed retrospectively. The clinical records of patients who underwent ureterolysis between January 2005 and April 2019 because of ureteral obstruction caused by RPF were examined. According to the type of surgery, the patients were divided into two groups as Group 1 (open ureterolysis) and Group 2 (laparoscopic ureterolysis). Demographic features, preoperative-postoperative renal functions, duration of follow-up with ureteral stents, and perioperative-postoperative complications were examined. The requirement of ureteral stent placement during the follow-up period was accepted as unsuccessful ureterolysis. Ureterolysis was performed in 13 patients and 23 renal units. Eleven of these patients were men and two were women. The median age of the patients was 54 (44-68) years. There were six patients and 12 renal units in Group 1 and seven patients and 11 renal units in Group 2. Postoperatively, a total of four patients (30%) had minor complications (Clavien-Dindo 1-2) and one patient had a major complication (Clavien-Dindo 3a). Ureterolysis was determined to be effective in 21 of the renal units (91%) [11/12 (92%) in Group 1 10/11 (91%) in Group 2]. No statistically significant difference was found between the groups in terms of the success and complication rates ( = 1 and  = 0.529, respectively). Postoperative hospitalization length and recovery time to return to normal preoperative activities were significantly shorter in Group 2 than in Group 1 ( = 0.011 and  = 0.041, respectively). The success and complication rates were similar between the open and laparoscopic methods for ureterolysis. Laparoscopic approach was advantageous over open approach in terms of postoperative hospitalization length and recovery time to return to normal preoperative activities.
