BACKGROUND: Laparoscopic renal surgery has become an accepted approach for benign disease in adult and pediatric urology. We present our experience in renal laparoscopy in infants during the past 5 years and evaluate our series to establish the safety and efficacy of such procedures in children. MATERIALS AND METHODS: From August 1999 to December 2004, we performed 32 renal laparoscopic procedures on 31 children aged 12 months to 16 years (mean, 42 months). Twenty-seven patients underwent unilateral retroperitoneal nephrectomy; 1 child with Denis Drash syndrome underwent transperitoneal bilateral nephrectomy; 2 children underwent renal cyst unroofing; and 1 child with lymphoma underwent retroperitoneal laparoscopic renal biopsy. Indications for surgery were: renal function <9% in cases of unilateral nephrectomy; the prevention of renal neoplastic changes in the patient with Denys-Drash syndrome; symptomatic large renal cysts; and suspected lymphoma not diagnosed with a previous percutaneous biopsy. RESULTS: All procedures were completed laparoscopically. In 6 cases, the accidental opening of the peritoneum did not require conversion to open surgery. Intraoperative blood loss was minimal. One patient who underwent a retroperitoneal nephrectomy required a blood transfusion for postoperative bleeding into the retroperitoneal space. Twenty-four of 27 unilateral retroperitoneal nephrectomy patients were discharged on postoperative day 2. Mean follow-up was 30 months (range, 6-64 months). Cosmetic results were excellent in all patients and no long-term complications have been encountered so far. CONCLUSION: Laparoscopic urologic surgery may be performed in children with minimal morbidity, minimal postoperative discomfort, improved cosmetic results, and a short hospital stay.
