Abstract
From January 1984 to June 1986, 151 patients with partial or complete staghorn calculi were treated at our department either by extracorporeal shock wave lithotripsy (ESWL), percutaneous nephro-lithotomy (PCN) or a combination of both techniques. According to the stone burden, distribution of stone load, renal anatomy, radiodensity and chemical composition of the calculi, 31 patients (20%) underwent ESWL-monotherapy, 42 patients (28%) PCN-monotherapy, and 78 (52%) were treated by the combination (PCN+ESWL). The overall rate of severe complications amounted to 8%. Auxiliary measures were necessary in 35% after ESWL-monotherapy, 19% after PCN-monotherapy and 14% after the combination. Follow-up data with a mean observation time of 18 months were available for 89 patients: the stone-free rate for ESWL, PCN and the combination was 50%, 77%, and 60%, respectively. Recurrent stone formation occurred in 4% after PCN and in 6% after the combination. The incidence of urinary tract infection was significantly lower than before treatment (21% vs 36%).
