title: ESWL monotherapy for large stones and staghorn calculi.
abstract: From December 1986 through March 1988, 52 renal units (RU) with large stone burden have been treated by ESWL monotherapy. In all patients a ureteral stent was placed prior to lithotripsy, to provide drainage of the kidney during the period of stone passage. Data of 43 RU were collected for the present report. Complications ; following treatment were infrequent (2%), whereas auxiliary measures became necessary in 32% of the patients. After a mean follow-up of 9.1 months, 54% of the patients were found stone-free. Stratification according to different stone types and compositions revealed that none of the 7 patients with complete staghorns could be completely cleared and that struvite stones had a significantly better outcome than calcium oxalate stones (75 vs. 25%). Consequently, for a large but not excessive stone burden in a normal or only slightly dilated renal collecting system, ESWL monotherapy under the protection of a ureteral stent may be a comparably safe alternative to percutaneous surgery.
