ABSTRACT
Successful removal of stones in percutaneous nephrolithotomy requires the accurate placement of a percutaneous track that provides direct access for stone manipulation. Supracostal approach is usually avoided be-cause of concerns about potential chest complications. We evaluated the hazard, safety and efficacy of supracostal approach for percutaneous nephrolithotomy. During the years 2003-2005 a total of 24 patients underwent PCNL through a supracostal track at Al-Hussain University Hospital. The indications for a supracostal approach were upper caliceal stone resistant to ESWL, upper caliceal stone with narrow neck, upper ureteric stone, Staghorn stone and sizable pelvic stone in a highly situated kidney. In 22 patients the punctures were performed just above the 12th rib; while in 2 cases the punctures were performed above the 11th rib. The data were analyzed for stone clearance, intra-operative and post-operative complications. Twenty one patients [87.5%] were rendered stone-free or had clinically insignificant residuals by PCNL alone. Overall complication was [20.8%]. Chest complications developed in only 2 patients [8.3%] in the form of hydro-pneumothorax and were managed successfully by intercostal chest tube drainage with an under water-seal connection. The study concluded that with proper choice of candidates, supracostal access for PCNL is safe and effective. The possible inadvertent pleural injury is rare and is easily manageable
