urinary tract urolithiasis lithotripsy lithotriptor
summary
- Objective. Since 1989 in the Department of Ultrasonics, Institute of
- Fundamental Technological Research, Polish Academy of Science, researches
- have been made to work out new model of lithotriptor, which was finally
- constructed in 1993. Our objective was to evaluate preliminary results of urinary
- stones lithotripsy using this lithotriptor.
- Patients and methods. We evaluated 18 patients with urinary stones treated
- from August to November 1996 by Extracorporeal Shock Wave Lithotripsy using
- the new model of lithotriptor. 18 Sessions of ESWL were performed. Stones
- sizes varied from 7x6 mm to 24x18 mm. 15 stones were located in kidneys, 3 in
- ureters. Plain abdominal X-ray on the 7-th day and ultrasound examination
- on the 1-st and 7-th day after treatment were done during the follow-up.
- Results. Desintegration of stones was found out in all cases after one
- treatment. ESWL with new model of lithotriptor resulted in complete stone
- discharge in 5 cases, decrease in stone size in 7 cases, desintegration without
- discharge in 6 cases. ESWL Sessions were painless regardless of shock wave
- energy. No pathological changes in renal ultrasound after treatment were found.
- Conclussions. New model of lithotriptor meets clinical and safety
- re±uirements of lithotripsy. Preliminary evaluation showed efficacy comparable
- to other second generation lithotriptors.
