Abstract

The collaborate studies of clinical application of Extracorporeal Shock Wave Lithotripsy (ESWL) using Sonolith 2000, performed at Departments of Urology of Nara Medical University, the University of Tokai School of Medicine and Wakayama Medical College between March and August 1987, were reported.
In total 155 ESWL sessions were carried out on 111 patients suffering from in total 119 upper urinary tract stones. The localization system using ultrasound imaging with a computer assissted multiarticulated arm were evaluated as excellent or effective in 117 cases (98.3%). The stone fragmentations were evaluated as excellent (≤3mm) or effective (≤5mm) in 101 cases (84.9%). On the X-ray film obtained six weeks after the final ESWL treatments, 61 cases (51.3%) were free from stone fragments, 20 cases (16.8%) had sand-like fragments and 18 cases (15.1%) had stone fragments less than 5mm. 99 cases (83.2%) without stone or with stone fragments less than 5mm were considered to be with satisfactory results.
No serious adverse effect was observed, but petchia on the flanks where shock wave penetrated and mild hematuria were observed in all cases. It is concluded that ESWL treatment using Sonolith 2000 is applicable in the managements of patients with the upper urinary tract stones without serious adverse effects.
