Urologic experience with the Dornier multipurpose lithotripter MPL 9000.
From March, 1988 until October, 1989, 502 patients with 603 stones were treated with the Dornier multipurpose lithotripter MPL 9000. Sixty-six percent of the stones were situated in the calix, 29.6% in the renal pelvis, 3% in the upper, and 1% in the distal ureter; 18.4% of the stones were radiolucent.  Multiple MPL treatments were performed in 8.6%.  In 6.1% fragments post-ESWL treatment were larger than 5 mm.  In 58.6% of the treatments were performed without using analgesia or anesthesia. Intravenous anesthesia was used in 22.3%, analgesia and sedation in 16.9%, general anesthesia in 1.4%, and epidural anesthesia in 0.8%.  After 3 months follow-up 73.1% were stone-free.  Residual fragments were found in the upper calix in 1.1%, in the middle calix in 5.2%, in the lower calix in 13.4%, in the renal pelvis in 5.9%, and in the ureter in 1%.  The MPL 9000 has been proven to be as effective for the treatment of renal stones, while difficulties in localizing ureteral stones were noted.  The major number of treatments were performed without any analgesia or anesthesia. No major complications were encountered.
