Place of extracorporeal shock-wave lithotripsy (ESWL) in management of cystine calculi.
We treated 12 patients with sixteen renal and one ureteral cystine stones primarily with extracorporeal shock-wave lithotripsy (ESWL). Among the stones thirteen were greater than 25 mm. In four stones less than 25 mm, three stones completely disappeared and 1 was reduced to small fragments, following ESWL. In thirteen stones greater than 25 mm, twelve were treated by ESWL initially, and one by surgery. Of the 12 cases treated initially by ESWL, 4 became stone-free, 4 remained with small fragments, and 1 remained with large fragments. Two patients were operated on because of poor response to ESWL and 1 patient lost kidney function because of prolonged obstruction. Disintegration of cystine stones greater than 25 mm required an average of 8,522 shock-waves in 4.33 sessions. The problems associated with application of ESWL monotherapy to cystine stones are presented.
