[ESWL with the Lithostar--experience with 3,000 treatments]

The experiences with 3,000 extracorporeal shock wave lithotripsies of kidney and ureteral calculi using the Lithostar are reported. Indications, contraindications and therapeutic approach are reviewed and the importance of out-patient follow-up is stressed. The success rate of 75% (including further spontaneous passage of residual desintegrated calculi) is good in the view of an unselected and unfavourable patient population. In the other patients a second ESWL treatment may be necessary. In the initial period in 6% of the patients percutaneous nephrolitholapaxy or open operation have been performed whereas in the last 100 patients it was not necessary.
