Laparoscopic partial nephrectomy in duplex kidneys in infants and children: results of an European multicentric survey

Abstract

Background

We aim to report a 5-year retrospective multicentric European survey about the outcome of laparoscopic partial nephrectomy in infants and children with duplex kidneys.

Methods

The data of fifty-two children underwent laparoscopic partial nephrectomy (42 upper-pole nephrectomies and 10 lower-pole nephrectomies) in six European centers of Pediatric Surgery, were collected and analyzed. Median age at surgery was 5.1 years (range 6 months–9.7 years). There were 32 girls and 20 boys. In 37 patients, the left side was affected and in 15 patients the right side. For the right side, 4 trocars were used and for the left side 3/4 trocars. Special hemostatic devices were used for dissection and parenchymal section in all centers. We assessed intraoperative and postoperative morbidity.

Results

Median length of surgery was 166.2 min (70–215 min). No conversion to open surgery nor intraoperative bleeding was reported. Mean hospitalization was 3.5 days. We recorded 10/52 complications (4 urinomas, 2 recurrent UTIs, 4 prolonged urinary leakage), all managed conservatively. Reoperation rate was 0 %. No loss of renal function on the residual kidney moiety was recorded in all operated patients.

Conclusions

Laparoscopic partial nephrectomy remains a technically challenging procedure performed only in pediatric centers with high experience in minimally invasive surgery. Although the median operative time was higher than 2 h, we recorded no conversions in our series. The complication rate remains high (10/52–19.2 %). All were II grade complications according to Clavien–Dindo classification and were treated conservatively without the need of other surgical procedures.
