The aim of this study was to evaluate the feasibility and benefits of retroperitoneal laparoscopy (RL) in this age group, compared to open surgery. MATERIAL AND METHODS From 2012, the choice of the approach for children less than twelve months of age was decided according to the laparoscopic experience of the surgeon; two surgeons operated by RL, 3 tro- cars standardized technique (5, 3, 3 mm) while others operated them by dorsal lumbotomy (DL). Analgesics and criteria for discharge were conducted according to pre-established protocol. Intra- and postoperative parameters have been analyzed retrospectively. RESULTS During 5-year period, 24 RL (mean age 7 months: 1,5–11) 55 DL (5,2 months: 2–11), were in- cluded with a mean follow-up of 27 months (5–63). Postoperative drainage was performed by double-J stent in 13 (RL) and 5 patients (DL) or external stent in 11(RL) and 50 patients (DL). There was no conversion in RL. Hospital stay and IV analgesics duration were significantly lower in the RL group (2.83 days vs 2.35 days, p=0.02 respectively) while operative time was significantly longer (163.05 min vs 85.76 min, p=0.001). A redo surgery was needed for one patient in each group (UPJ stenosis). 34 % of DL 12 % of RL patients were operated by the fellow assisted by the senior staff. CONCLUSIONS Although, RL remains challenging in infants with longer operative time, it is feasible without added morbidity compared to open surgery. The hospital stay and analgesic requirements are less. Some drawbacks still need to improve: higher use of double J stent and the lower number of patients done by fellows of pediatric urology.
