Outpatient-based extracorporeal shock wave lithotripsy using EDAP LT-01.
Between March 1988 and March 1990, 751 patients were treated with shock wave lithotripsy using EDAP LT-01. Six hundred and eight patients had renal stones while 143 patients had stones located in the ureter. Because of difficulties in locating ureteric stones with ultrasound 92% of them were pushed back to the kidney before treatment. The mean stone size was 10 mm, range 4-30 mm. Patients with stones bigger than 15 mm had a double J-stent placed before treatment. The mean number of treatments per patient was 1.7 (range 1-8). Sixty-six per cent of the patients with renal stones were completely stone-free after ESWL monotherapy. Another 5% became stone-free after auxiliary procedures in the ureter, because of retained fragments. Fragments equal to or less than 4 mm were retained in 14% of the patients with the renal stones. Of the patients with ureteric stones mobilised back to the kidney 95% were rendered stone-free after ESWL. Most patients experienced no or very little discomfort during the treatment and only 29% of them received analgesics. General of epidural anaesthesia was given to 1% of the patients. Because of the low demand for analgesia or anaesthesia, 99% of the patients with renal stones were treated on an outpatient basis. During the second year, 74% of the patients with ureteric stones were treated on an outpatient basis.
