FEMORAL NEUROPATHY FOLLOWING PERCUTANEOUS NEPHROLITHOTOMY OF A PELVICKIDNEY

Management of nephrolithiasis within a pelvic kidney presents a novel challenge to the urologist. We report on a patient who underwent urete ral stent placement prior to extracorporeal shock-wave lithotripsy (ES WL). Following ESWL, the ureteral stent calcified at the vesical and r enal ends, requiring ''sandwich therapy'' of percutaneous nephrolithot ripsy, ESWL, and percutaneous nephroscopy. Percutaneous access to the pelvic kidney through a posterior approach was complicated by femoral neuropathy manifested by an inability to walk. With 6 months of aggres sive physical therapy, the patient is now able to ambulate with diffic ulty using a walker.
