A Modified Two-Layer Suture Technique for Transperitoneal Laparoscopic Partial Nephrectomy: Single-Center Clinical...

Area of Science:

• Urology
• Surgical Innovation
• Nephrology

Background:

• Laparoscopic partial nephrectomy (LPN) is a standard procedure for kidney tumor removal.
• Optimizing surgical techniques in LPN is crucial for preserving renal function.
• Traditional two-layer suture methods can impact operative time and renal outcomes.

Purpose of the Study:

• To evaluate the feasibility and efficacy of a modified two-layer suture method in LPN.
• To compare the outcomes of the modified suture technique against the traditional two-layer suture.
• To assess the impact of suture methods on surgical characteristics and postoperative renal function.

Main Methods:

• A comparative study involving 60 LPN patients, divided into modified (30) and traditional (30) suture groups.
• Surgical metrics recorded included operative time, warm ischemic time (WIT), estimated blood loss (EBL), and glomerular filtration rate (GFR).
• Univariable and multivariable linear regression analyses were employed to determine correlations.

Main Results:

• No significant differences were observed in patient/tumor characteristics or postoperative creatinine/BUN levels between groups.
• The modified suture group exhibited significantly shorter clamping times (15 vs. 23 min) and less GFR reduction (p < 0.05).
• The modified two-layer suture was identified as an independent factor influencing clamping time and GFR reduction.

Conclusions:

• The modified two-layer suture method is a feasible and effective technique for LPN.
• This modified approach offers potential advantages in reducing warm ischemia time and preserving renal function.
• Further research may validate these findings and promote wider adoption of the modified technique.
