Evolving renorrhaphy technique for retroperitoneal laparoscopic partial nephrectomy: single-surgeon series.

Area of Science:

• Urology
• Surgical Innovation
• Nephrology

Background:

• Partial nephrectomy is crucial for renal tumor management.
• Renorrhaphy technique impacts surgical outcomes and renal function.
• Evaluating renorrhaphy methods is essential for optimizing laparoscopic partial nephrectomy.

Purpose of the Study:

• To compare surgical outcomes of two renorrhaphy techniques in retroperitoneal laparoscopic partial nephrectomy.
• To analyze the impact of renorrhaphy on perioperative renal function.
• To identify optimal renorrhaphy methods for improved patient outcomes.

Main Methods:

• Retrospective analysis of 526 patients undergoing retroperitoneal laparoscopic partial nephrectomy.
• Comparison of one-layer, interrupted, figure-of-eight suture versus two-layer, continuous, unknotted suture renorrhaphy.
• Evaluation of patient demographics, tumor characteristics, operative outcomes, and renal function.

Main Results:

• The two-layer, continuous, unknotted suture group demonstrated shorter warm ischemia time (P=.021).
• Faster Jackson-Pratt drain removal (P=.029) and shorter hospital stays (P=.037) were observed with the two-layer technique.
• A trend towards better preservation of glomerular filtration rates (P=.045) was noted, with the two-layer technique being an independent predictor of improved renal function.

Conclusions:

• Two-layer, continuous, unknotted renorrhaphy offers superior outcomes compared to one-layer, interrupted techniques in laparoscopic partial nephrectomy.
• This technique is associated with reduced warm ischemia time, shorter hospital stay, and better renal function preservation.
• Further clinical follow-up is recommended to confirm long-term benefits.
