Retrospective analysis of laparoscopic vascular hitching ureteropelvic junction obstruction induced by extrinsic vessel compression

Objective To evaluate the value and experience of laparoscopic vascular hitching procedure treatment of ureteropelvic junction obstruction (UPJO) induce by extrinsic vessel compression. Methods Patients diagnosed as UPJO in our hospital from 2014 to 2017, the data of 13 patients with UPJO due to extrinsic vessel treated with laparoscopic vascular hitching procedure were retrospectively analyzed. Results The operations were successfully performed in all patients. The operative time was 65-125 min. The mean blood loss was 40 ml. Diuretic experiments were performed during the operation. All 13 cases had not been switched to open surgery. Seven patients with lumbar and abdominal pain all disappeared 3 months later. CT examination at 3 months later revealed that hydronephrosis was improved; After 6 months,the hydronephrosis was relieved. And a diuretic test was conducted, the hydronephrosis did not worsen. Conclusions For patients with UPJO caused by extrinsic vessel compression, laparoscopic vascular hitching procedure was effective. Key words: UPJO; Laparoscopy; Extrinsic vessel compression; Hitching
