PURPOSE: We determined the preferred treatment of staghorn calculi.
MATERIALS AND METHODS: Between January 1992 and December 1994 we performed a prospective, randomized, single center study involving 50 kidneys with complete staghorn calculi: 27 renal units were treated with extracorporeal shock wave lithotripsy (ESWL) monotherapy (group 1) and 23 were treated with combined (initial) percutaneous nephrostolithotomy with ESWL (group 2). The 2 treatment groups were compared regarding stone size, grade of collecting system dilatation and urine culture at presentation. The number of treatment sessions, narcotic doses, renal colic episodes, septic complications, unplanned ancillary procedures, length of hospitalization, total treatment duration and stone-free rate at 6 months were recorded and compared.
RESULTS: At the conclusion of therapy the stone-free rate was significantly greater in group 2 than in group 1 (74 versus 22%, respectively, p = 0.0005). The complication rate was significantly greater in group 1, with 15 septic complications (fever greater than 38.5C for longer than 3 days) in 10 patients compared to only 2 episodes in group 2 (p = 0.007). The unplanned ancillary procedure rate was significantly greater in group 1 (8 procedures in 7 patients versus 1 procedure in group 2, p = 0.03). The overall treatment length was significantly shorter in group 2 (1 versus 6 months, p = 0.0006). There was no significant difference in the number of procedures performed with anesthesia or in the number of hospitalization days between the 2 treatment groups.
CONCLUSIONS: Combined percutaneous nephrostolithotomy and ESWL should be recommended as the first line treatment choice for most patients with staghorn stones.
