    Abstract:
    Purpose: We retrospectively reviewed the perioperative outcomes of mini-laparoscopic procedure in the treatment of ureteropelvic junction obstruction (UPJO) in children and adults. Methods: From August 2009 to March 2017, 229 patients referred to our center to repair UPJO by mini-laparoscopic operation. In 203 cases, dismembered pyeloplasty was accomplished, while in other 26 cases, crossing aberrant vein division and crossing artery upward transposition were performed. A follow-up renal ultrasound was done on the cases 3 and 6 months after surgery. During the follow up period, if the patients had persistent hydronephrosis or sustained clinical complaints, diethylenetriamine pentaacetic acid (DPTA) scan was done to rule out the stenosis. Results: Among 229 patients, 140 patients were younger than 18 years (Range: 2 months-18 years old, mean: 3.01 ± 1.2 year) and others were scheduled as Adult (Range: 18-57 years old, mean: 35.12 ± 7.54 year). Total clinical and radiological success rates were 99.5% (228/229) and 86.5% (198/229) respectively. Mean operative times were 127.4 ± 20.3 minutes in dismembered pyeloplasty and 110.6 ± 12.7 minutes in crossing vessel transposition surgery. Mean of hemoglobin decreasing in children and adults was 0.3 ± 0.1 mg/dL; P = .26, and 0.5 ± 1.5 mg/dL; P = .13, respectively. Length of hospital stay was 3.41 ± 0.6 days in dismembered pyeloplasty and 2.1 ± 0.6 days in patients with crossing vessel transposition surgery. We did not suture the skin incision in the entrance site of 3 mm ports and the surgical scar was hardly visible after 6 months. Conclusions: The results of our study suggest that mini-laparoscopic pyeloplasty in adults and particularly in children is feasible, and it seems to be safe and effective in the treatment of UPJO. Furthermore, the patients tolerated the surgery well and they appreciated its outstanding cosmetic outcomes.
