Percutaneous Nephrolithotomy: One Stage or Two?

Abstract
Cases (250) of percutaneous nephrolithotomy (PNL) are described. Cases (150) were treated in 2 stages, 100 in a single stage. The 1-stage method has been shown to be as safe as the 2 stage method but should be reserved for those with experience of the technique and who possess adequate instrumentation. PNL proved preferable to open stone surgery and a useful alternative to extracorporeal shock wave lithotripsy (ESWL).
