Risk factor analysis for infection and bleeding after lateral decubitus percutaneous nephrolithotomy

Area of Science:

• Urology
• Nephrology
• Surgical Outcomes

Background:

• Percutaneous nephrolithotomy (PCNL) is a key procedure for kidney stones.
• Understanding risk factors for infection and bleeding is crucial for improving PCNL outcomes.
• Lateral decubitus positioning is a common approach for PCNL.

Purpose of the Study:

• To identify independent risk factors for postoperative infection and bleeding after lateral decubitus PCNL.
• To provide data for preventing complications and enhancing surgical success in PCNL procedures.

Main Methods:

• Retrospective analysis of 356 patients undergoing lateral decubitus PCNL for kidney and upper ureteral stones (Jan 2015 - Aug 2022).
• Collected data included patient demographics, perioperative details, and stone characteristics.
• Univariate and multivariate logistic regression analyses were used to determine risk factors.

Main Results:

• Postoperative infection rate was 19.31%; bleeding rate was 12.07%.
• Independent risk factors for infection: multiple stones (P < .001), stone size (P < .001), and stone co-infection (P = .012).
• Independent risk factors for bleeding: multiple stones (P = .008) and stone size (P = .014).

Conclusions:

• Multiple stones, larger stone size, and co-infection are significant risk factors for postoperative infection in lateral decubitus PCNL.
• Multiple stones and stone size are significant risk factors for postoperative bleeding following this procedure.
