[The clinical efficacy of outpatient extracorporeal shock wave lithotripsy].
From March 1989 through December 1989, 123 patients, 9 to 78 years old, were treated by extracorporeal shock wave lithotripsy (ESWL) with the Wolf Piezolith device. Outpatient treatment was performed routinely. Anesthesia was not required in all of the patients. No analgesia or sedation was given routinely. When pyuria had been found before treatment, a course of prophylactic oral antibiotics was given. Treatment consisted of 2000 to 6000 shocks in adults. The need for re-treatment was decided on the basis of the follow up X-rays. Fragmentation into particles 5 mm in size or less occurred in 144 of the 149 renoureteral units (96.6%). Unfragmented stones were treated successfully by the combination therapy of ESWL and fiberoptic transurethral nephroureterolithotripsy (f-TUL). Of 144 renoureteral units, 3-month follow-up data are available for 96. Among the 96 units, the rate of being free of stones was 67 per cent for renal stones and 96 per cent for ureteral stones treated in situ. The over-all rate of being free of stones was 80.2 per cent. There were no significant complications. Ultrasound imaging has proved to be as effective as X-ray imaging. Outpatient ESWL with the Wolf Piezolith device is considered to be safe and efficient for the initial treatment of urinary stones. On the other hand, ESWL monotherapy is not sufficient for the treatment of complete staghorn calculi or long-term impacted ureteral calculi. We think that the combination use of ESWL and f-TUL is the most effective procedure for treatment of complicated stones.
