Retroperitoneal laparoscopic vs open partial nephroureterectomy in children.
OBJECTIVE
To compare the results of retroperitoneal laparoscopic with open partial nephroureterectomy.


METHODS
Laparoscopic retroperitoneal partial nephroureterectomy was undertaken in 15 children (13 upper and two lower poles; median age at the time of surgery 61 months, range 5-212). A three-trocar retroperitoneal approach was used. The polar vessels were identified and either coagulated or clipped before transecting the parenchyma using a harmonic scalpel. An additional 13 consecutive children underwent similar procedures (11 upper and two lower poles) by conventional open surgery (median age at surgery 16 months, range 1.5-72).


RESULTS
One patient in the laparoscopy group required conversion to open surgery because of a peritoneal tear and was excluded from the analysis. The mean (range) operative duration was 146 (50-180) and 152 (75-240) min for the open surgery and laparoscopy groups, respectively. The blood loss was minimal (< 20 mL) in both groups. The mean (range) hospital stay was 1.4 (1-3) and 3.9 (3-5) days for the laparoscopy and open groups, respectively (P < 0.001). Eight patients were discharged on the day after the laparoscopic procedure. In addition, of those patients in the laparoscopy group who had a lower-pole partial nephrectomy, one had a urinoma after surgery.


CONCLUSIONS
Laparoscopic retroperitoneal partial nephrectomy is a safe and feasible procedure in children. It requires a similar operative duration to that of an open procedure. The main advantage to the laparoscopic approach is that it significantly decreases the hospital stay compared with that after an open procedure.
