Unilateral percutaneous nephrolithotomy (PCNL) temporarily reduces kidney function in both treated and untreated kidneys. Renal function gradually recovers post-surgery, highlighting the need for careful post-operative monitoring.
Area of Science:
- Nephrology
- Urology
- Surgical Outcomes
Background:
- Limited understanding of immediate renal function changes after percutaneous nephrolithotomy (PCNL).
- Previous studies focused on long-term effects on renal structure and function.
Purpose of the Study:
- To assess the immediate impact of unilateral PCNL on bilateral renal function.
- To evaluate changes in creatinine clearance (CrCl) in the early post-operative period.
Main Methods:
- Prospective study of 40 patients undergoing unilateral PCNL.
- Separate estimation of CrCl for treated and untreated kidneys post-surgery.
- Analysis of bilateral renal function changes.
Main Results:
- A similar pattern of CrCl decline observed in both kidneys, more pronounced on the treated side.
- Progressive decrease in CrCl followed by bilateral improvement towards pre-operative levels.
- Temporary bilateral reduction in renal function post-PCNL.
Conclusions:
- Unilateral PCNL causes a transient decline in the function of both kidneys.
- Intensive post-operative care is crucial during the early recovery phase.
- Monitoring bilateral renal function is important after PCNL.
