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.
