[Retroperitoneoscopy. Technique and experiences with the first 100 patients]

Area of Science:

• Minimally Invasive Surgery
• Urologic Surgery
• Laparoscopic Techniques

Context:

• Retroperitoneoscopy, initially performed in the 1970s, saw a clinical advancement in 1992 with Gaur's balloon-dissecting technique.
• Previous experience with transperitoneal laparoscopy in the upper retroperitoneum informed early developments.
• The study builds upon existing retroperitoneoscopic methods, focusing on refinement and simplification.

Purpose:

• To modify and simplify the balloon-dissecting technique for retroperitoneoscopy.
• To evaluate the safety and efficacy of the modified hydraulic video-optically controlled balloon dissection.
• To assess the learning curve, operative times, complication rates, and patient outcomes for 100 retroperitoneoscopic procedures.

Summary:

• A modified hydraulic balloon dissection technique was applied to 100 retroperitoneoscopic procedures in 98 patients between 1992 and 1995.
• Procedures ranged from simple renal biopsies and cyst resections to complex nephrectomies and pyeloplasties.
• Outcomes demonstrated that operating time, complications, and conversion rates were dependent on procedure difficulty and the surgeon's learning curve, with a mean hospital stay of 4.7 days for uncomplicated cases.

Impact:

• Retroperitoneoscopy has become a standardized procedure, integrated into urology training programs.
• The refined technique offers a viable minimally invasive approach for a range of urologic conditions.
• Demonstrates the feasibility and benefits of minimally invasive surgery in the retroperitoneal space, reducing patient recovery time.
