The effect of double-J stent in extracorporeal shock wave lithotripsy monotherapy of staghorn calculi / 대한비뇨기과학회지

ABSTRACT

From June 1989 to October 1991. 52 patients with renal staghorn calculi (34 with incomplete staghorn renal calculi and I8 with complete staghorn calculi) underwent extracorporeal shock wave lithotripsy. monotherapy by Northgate SD-3 Iithotriptor. Of 52 patients, 27 were treated without preoperative double-J stenting. while 25 underwent double-J stenting before extracorporeal shock wave lithotripsy. The mean shock waves per patients were gradually increased in proportion to stone burdens rather than the insertion of double-J stent. The average duration of hospitalization was shorter for The group who received prophylactic double-J stenting. The incidence of postoperative complications such as ureteral obstruction, colic, fever decreased in double-J stenting group, but was not statistically significant (p>0.05). 62% (32 cases) of the patients were free of stones after 6 months but double-J stenting did not influence the rate free of stones.
