Abstract
OBJECTIVE: To prospectively evaluate the safety and efficacy of the supracostal approach for percu-taneous nephrolithotomy (PCNL), as it is usually avoided because of concerns about potential chest complications. PATIENTS AND METHODS: Between August 1998 and August 2001, 465 patients underwent PCNL. Supracostal access was obtained in 62 patients (63 renal units), comprising 13% of the procedures. The indications for a supracostal approach were staghorn, upper ureteric, superior calyceal stones and high-lying kidneys. The data were analysed for stone clearance, need for additional punctures and the complications associated with supracostal puncture. RESULTS: The supracostal was the only access in 63% of the PCNL procedures. Additional punctures were required mainly for staghorn stones (15 of 23). Overall, 90% of the patients were rendered stone-free or had clinically insignificant residuals with PCNL alone. In patients with staghorn stones, they were completely cleared in 84% of renal units. Significant chest complications developed in three (5%) patients, which required insertion of a chest tube. One (2%) patient developed haemothorax secondary to injury of the intercostal artery. All the patients recovered uneventfully. CONCLUSIONS: These results indicate that supracostal access provides high clearance rates with acceptable complications; it should not be avoided for fear of chest complications. A chest X-ray after surgery should be routine, to detect any complication.
