title: [The treatment of staghorn calculi].
abstract: Between May 1989 and November 1991, 19 staghorn calculi were treated by extracorporeal shock-wave lithotripsy (ESWL) with a Dornier MFL 5000 or Northgate SD-3. The 19 calculi were evaluated. Treatment was with monotherapy by ESWL in 9, combination percutaneous nephrolithotomy (PNL)-ESWL in 9, and nephrostomy in 1. Of the patients, 14 had a cross stent catheter pre-ESWL treatment to improve fragment evacuation. Radiologic follow up in 19 kidneys revealed that 57.9% were stone free. We arbitrarily separated our cases into 3 groups: struvite renal calculi, calcium carbonate calculi and others. Result of stone-free rate was 100% for stones consisting of struvite, and 14. 3% for stones consisting of calcium carbonate. In our opinion, the best indication of monotherapy by ESWL is for staghorn calculi, which consists of struvite, without marked dilation of pelvis and calyces.
