Summary
Nephrostomy tube dwelling time after percutaneous nephrolithotomy (PCNL) is influenced by factors like repeat procedures and complications. Expediting preoperative evaluation and completing PCNL in one session may reduce drainage time.
Area of Science:
- Urology
- Nephrology
- Surgical Outcomes
Background:
- Limited understanding of nephrostomy tube impact on patient morbidity and quality of life.
- Nephrostomy tubes are often used in patients undergoing percutaneous nephrolithotomy (PCNL).
Purpose of the Study:
- To determine nephrostomy tube dwelling time in PCNL patients.
- To identify factors influencing tube dwelling time.
Main Methods:
- Retrospective analysis of 165 patients undergoing PCNL.
- Evaluation of tube dwelling time and associated clinical variables.
Main Results:
- Mean tube dwelling time was 21 days, with preoperative drainage for urgent reasons being significant (31 days).
- Multivariate analysis identified secondary PCNLs and postoperative complications as key factors influencing dwelling time.
- Age showed a trend towards correlation with intubation time, but not statistically significant.
Conclusions:
- Preoperative patient evaluation and preparation significantly affect tube drainage duration.
- Expeditious preoperative management and single-session PCNL can minimize nephrostomy tube indwelling time.
