This study details a modified retroperitoneoscopic nephrectomy technique for children with benign renal disease. The approach, using 2 mm. instruments and prone positioning, proved safe and effective with no complications.

Area of Science:

  • Pediatric Urology
  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Retroperitoneoscopic nephrectomy is a minimally invasive surgical option for pediatric renal disease.
  • Optimizing this technique is crucial for improving patient outcomes and reducing complications.

Purpose of the Study:

  • To describe modifications to the retroperitoneoscopic approach for nephrectomy in children with benign renal disease.
  • To evaluate the safety and efficacy of using 2 mm. instrumentation and prone patient positioning.

Main Methods:

  • 14 pediatric patients underwent retroperitoneoscopic nephrectomy in the prone position.
  • A small incision allowed insertion of a dissecting device, followed by a 5 mm. cannula for pneumoretroperitoneum.
  • Dissection utilized 2 mm. instrumentation, with specimen retrieval through the largest port site.

Main Results:

  • The procedure was performed on 9 girls and 5 boys aged 3 months to 9.8 years.
  • Indications included chronic pyelonephritis, reflux with nonfunctioning kidney, and multicystic dysplastic kidney.
  • Mean operative time was 142 minutes, with estimated blood loss <15 ml. Average hospital stay was 2 days, with no complications.

Conclusions:

  • Modifications including prone positioning and 2 mm. instrumentation enhance the safety and efficacy of retroperitoneoscopic nephrectomy in children.
  • This technique offers a viable option for treating benign renal disease in pediatric patients.
  • Further research may explore long-term outcomes and broader applications of these modifications.
