Abstract

Purpose: We report the results of pediatric retroperitoneoscopic renal ablative surgeries, which

were performed with only three trocars.

Materials and Methods: We retrospectively reviewed the charts of children who underwent laparoscopic

urological procedures on the upper urinary tract at our institution between 2006 and 2012.

These procedures consisted of nephrectomies, nephroureterectomies and heminephroureterectomies.

The operations were performed retroperitoneoscopically with three trocars. The specimens

were removed intact through the primary trocar site.

Results: A total of 30 retroperitoneoscopic ablative surgeries were performed in 13 girls and 17

boys. The mean patient age was 7.8 ± 4.3 years (range, 1-14 years). The interventions consisted of

nephrectomy in 10 cases (33.3%), nephroureterectomy in 17 cases (56.6%) and heminephroureterectomy

in 3 (10%) cases. The open conversion rate was 3.3% (1/30). The difference between the

initial 10 cases and the latter 20 cases, in terms of mean operative time, was statistically significant

(144.5 vs. 115.78 minutes, respectively, P = .031). Apart from 3 nephroureterectomies, all of the

procedures (86.6%) were completed successfully using three trocars only, without the need for a

separate extraction incision. The patients were hospitalized for a mean duration of 2.2 days (range,

2-4 days). None of the patients required blood transfusion. We did not encounter any major perioperative

or postoperative complication.

Conclusion: Retroperitoneoscopic renal ablative surgery is a safe and effective treatment alternative

for a variety of upper urinary tract disorders in children.
