|December 1, 1985
Summary
Percutaneous nephrostolithotomy effectively removed large renal staghorn stones in 24 patients. Despite significant blood loss and fever in some, complete stone removal was achieved in most cases.
Area of Science:
- Urology
- Nephrology
- Surgical Technology
Background:
- Renal staghorn stones, particularly large ones (≥5 cm), pose significant treatment challenges.
- Percutaneous nephrostolithotomy (PCNL) is a minimally invasive option for stone removal.
Purpose of the Study:
- To evaluate the efficacy and outcomes of percutaneous nephrostolithotomy for large renal staghorn stones.
- To assess the feasibility of PCNL in managing complex stone burdens.
Main Methods:
- Retrospective analysis of 25 PCNL procedures for renal staghorn stones (≥5 cm) in 24 patients.
- Documentation of operative details, including access tracts, blood loss, and postoperative fever.
Main Results:
- Complete stone removal was achieved in all 25 cases, with only two patients having residual fragments.
- Twelve patients required multiple access tracts for complete clearance.
- Significant blood loss (>1000 ml) occurred in 16 patients, and fever (>38.5°C) in 19 patients.
Conclusions:
- Percutaneous nephrostolithotomy is a successful treatment modality for large renal staghorn stones.
- Further research is needed to compare PCNL with extracorporeal lithotripsy for these complex stones.
