Long-term results of kidney staghorn stone treatment with percutaneous nephrolithotripsy and extracorporeal shock-wave lithotripsy.

Between January 1988 and December 1990, 210 staghorn stones were treated in 185 patients with combination of percutaneous nephrolithotripsy and extracorporeal shock-wave lithotripsy. A total number of 105 patients (110 renal units) were controlled with a mean follow-up of at least 16 months after the last ESWL procedure. Of these, 77 renal units (70.0%) were stone free, 11 (10.0%) had stone particles less than 5 mm in largest diameter and 22 renal units (20.0%) had stone particles larger than 5 mm.
