[Laparoscopically ureteroplasty in treatment of congenital obstructive megaureter in childhood: report of 3 cases].

Objective: To explore the technique and efficacy of laparoscopic ureteroplasty in treatment of congenital obstructive megaureter in childhood.

Methods: Three children with congenital obstructive megaureter, all male, aged 7 approximately 24, underwent laparoscopic surgery. The dilated ureter was dissected and cut off near the place connecting the ureter and the bladder by laparoscopy. A double J tube was placed in the free ureter and connected with the urinary catheter by 7 - 0 wire. Then the free ureter was sutured with the bladder mucosa by laparoscopy.

Results: The operation duration was 80 to 200 min and blood loss was 30 to 50 ml. No complication developed. The double J was removed 10 days after the operation. Follow-up for 4 approximately 24 months showed good ureter drainage in all 3 cases without any infection, obstruction and hydrops.

Conclusion: Laparoscopic surgery to treat megaureter in childhood has the benefits of slight injury and fast recovery in a short-time follow-up.
