Purpose: To assess the safety and efficacy of percutaneous nephrolithotomy in patients more than 60 years old.

The only interesting finding in terms of patient characteristics was a significantly higher incidence of solitary kidney in patients aged 60 years or older (29% v 7%; P = 0.003). The success rates (stone-free patients and patients with residual …
