Comparison of videolaparoscopic versus open surgery for benign renal diseases in children.

INTRODUCTION Laparoscopic nephrectomy in children has become a reasonable alternative to open nephrectomy and has replaced open surgery for many kidney diseases. The aim of our study is to evaluate transperitoneal videolaparoscopic procedures in benign renal disease compared with the open surgical approach. PATIENTS AND METHODS 34 children aged between 17 days and 15 years (mean, 6.14 years) were divided into two nephrectomy groups. The first underwent transperitoneal videolaparoscopic nephrectomy and was composed of 21 patients (12 female and 9 male) aged between 2 months and 15 years (mean, 7.42 years). The second group underwent open nephrectomy and was composed of 13 patients (6 female and 7 male) aged between 17 days and 11 years (mean, 3.91 years). The groups were compared for time of anaesthesia, operating time, length of hospital stay, postoperative pain and time to restore oral intake. Short and long term complications were also evaluated. Statistical analysis was performed by a Student's t test, with a p value < 0.05 being considered significant. The study was approved beforehand by the Scientific Ethics Committee in our institution. RESULTS Statistically significant differences were observed only for the length of hospital stay. No cases in the laparoscopic group were converted into open surgery. There were no immediate or late complications. Blood loss was negligible and so it was not necessary to administer any transfusions. CONCLUSIONS In our experience, transperitoneal videolaparoscopic nephrectomy has similar results to those of open nephrectomy, except for hospitalisation times.
