Percutaneous nephrolithotomy and the flyer.

Percutaneous nephrolithotomy (PN) is a relatively new procedure that is coming in vogue for the removal of upper urinary tract stones. Although there are possible complications from the procedure--bleeding being the most common one--its advantages make it a desirable treatment modality vis-a-vis conventional surgery. This article describes the case of a pilot who underwent PN, but remained disqualified from flying status for 6 months because of an unfortunate complication.
