title: Percutaneous nephrolithotomy for complete staghorn renal stones.
abstract: To evaluate the effectiveness of percutaneous nephrolithotomy (PNL) in the management of patients with complete staghorn stones, a retrospective study was conducted on 110 patients at the Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia. The study was performed between September 1990 and September 1999. 144 procedures were performed on 119 renal units including 22 units (18.5%) that needed more than one sitting. Of them, 85 units (71.4%) were completely cleared after PNL and 11 units (9.2%) were left with insignificant residual fragments (< 4 mm). This gives a success rate of 78.6% for PNL as a monotherapy. Twelve patients with significant residual fragments required Extracorporal Shock Wave Lithotripsy (SWL) in addition to PNL. The overall success rate after PNL and SWL in 108 renal units was 89.4%. We found PNL useful in the management of patients with complete staghorn stones, either as monotherapy or in combination with SWL. It was associated with little morbidity and the procedure can be instituted even in centers with limited facilities.
