Fluid absorption occurs during percutaneous nephrolithotomy (PCNL) but is typically not clinically significant. Strategies like low-pressure systems and reduced irrigation minimize fluid absorption during PCNL.

Area of Science:

  • Urology
  • Nephrology
  • Surgical Research

Background:

  • Percutaneous nephrolithotomy (PCNL) utilizes significant irrigating fluid volumes.
  • Potential complications include calculus debris migration, infection, and systemic fluid absorption.

Purpose of the Study:

  • To evaluate fluid absorption during PCNL.
  • To assess its clinical and biochemical significance.
  • To identify maneuvers that can reduce fluid absorption.

Main Methods:

  • 148 patients undergoing PCNL were assessed for fluid absorption via expired breath ethanol concentration.
  • Factors studied included irrigation volume, tract number, pressure systems, and operative complications.

Main Results:

  • Fluid absorption was detected in all patients.
  • No patient exhibited clinical or biochemical signs of electrolyte imbalance.
  • Low-pressure systems, reduced irrigation, and staged procedures decreased fluid absorption.

Conclusions:

  • Fluid absorption is a consistent finding in PCNL.
  • It poses a risk of fluid overload, particularly in pediatric and compromised patients.
  • Minimizing irrigation, using low-pressure systems, and staging procedures reduce absorption and volume overload risks.
  • Fluid absorption may correlate with pyrexia, emphasizing preoperative infection control.
