PURPOSE: Retroperitoneal procedures were initiated in 1992 by balloon dissection of the retroperitoneum. More recently a new type of retroperitoneal access has been obtained by directly entering the retroperitoneum using the Visiport visual trocar. We present our initial experience with direct visual access to the retroperitoneum in the pediatric population. MATERIALS AND METHODS: A total of 31 children underwent retroperitoneal laparoscopy, including renal biopsy in 22, varicocelectomy in 5, renal cyst ablation in 3 and pyelolithotomy for a staghorn stone in 1. Patients were placed in the full flank position. A maximum of 3 ports was used and the initial trocar was placed under direct vision. The laparoscope was then used to dissect bluntly a working space in the retroperitoneum. RESULTS: All procedures were successful. Blood loss was minimal. Operative time was 4 hours for pyelolithotomy and less than 1 for the other procedures. Mean hospital stay was 1.5 days and all patients returned to normal activity at a mean of 6 days. Two minor complications developed. The peritoneum was inadvertently entered in 1 case, in which no further treatment was necessary and convalescence was uneventful and short. In another case severe arrhythmia developed, resulting in an aborted procedure. CONCLUSIONS: This technique is simple, safe and does not require extensive laparoscopic experience.
