[Laparoscopic extravesical ureteral reimplantation following Lich-Gregoire technique. Medium-term prospective study]

To evaluate our results of Laparoscopic extravesical ureteral reimplantation according to Lich-Gregoire technique in the of vesicoureteral reflux treatment.

Between August 2007 and January 2013, 108 renal units in 80 patients were treated. There were 23 patients with double renal system; in 5 cases were associated with obstruction, and 3 with completely impaired function of the upper pole and ipsilateral ureterocele presence.

Laparoscopic extravesical ureteral reimplantation was performed in all cases. The mean age was 52 months; The mean operative time was 70 minutes in unilateral and 144 minutes in bilateral. Three laparoscopic heminephroureterectomies were performed at the same time, with incision of ureterocele. The average hospital stay was 27 hours. Complete resolution was 96.5%. Mean follow-up was 27 months.

Laparoscopic extravesical ureteral reimplantation following Lich-Gregoire technique is effective against the unilateral, bilateral and associated with double renal system vesicoureteral reflux. It's possible to perform others procedures in a securely and concomitantly way (eg., heminephroureterectomy). A shorter hospital stay, more comfort and quicker recovery are achieved, with similar succes rates to open surgery.
