Abstract
Purpose
: To assess retrospectively the safety and efficacy of the supracostal approach in percutaneous nephrolithotomy (PCNL).
Patients and Methods
: Among 862 patients who underwent PCNL between April 1986 and December 1999, supracostal puncture was performed in 102. Their stones were either solitary (66.5%), multiple (15.7%), or staghorn (19.6%). Upper ureteral calculi were the commonest indication (32.4%). The interspace between the 11th and 12th ribs was used in all cases. After tract dilatation with telescopic metal dilators, pneumatic or ultrasound lithotripsy was used for fragmentation.
Results
: Complete clearance was achieved in 79.5%. Ten patients (9.8%) had pleural violation in the form of hydrothorax, pneumothorax, or hydropneumothorax. All of these patients were managed successfully by intercostal chest tube drainage.
Conclusion
: Supracostal puncture in a safe and effective approach with acceptable morbidity in selected cases of staghorn, upper ureteral, and upper caliceal calculi.
