[New approach to improving efficacy and objective assessment of the extracorporeal lithotripsy].
Clinical trials of the generator EMSE 220F XXP were conducted on the lithotriptor Dornie C" in the Research Institute of Urology from September 2203 to January 2004. Extracorporeal lithotripsy (ECL) was made in 158 patients (66 women and 92 men, age 11-89 years) with different clinical forms of nephrolithiasis. The analysis of nephrolith fragmentation showed high disintegration power of the generator in all nephrolithiasis forms (97.4%). Maximal energy intensity in ECL of nephrolithis was under 7 units, of ureterolithis--10 units. The number of additional sessions averaged 11.4%, mean Edose was 49.2 J. Complications of early postoperative period was detected in 4 (2.5%) patients. In two of them (1.3%) subcapsular hematomas 180 cm3 in size were detected. The other two patients developed exacerbation of pyelonephritis early after operation. It was managed conservatively. Thus, EMSE 220F-XXP is a novel, highly effective source of generation of shock-wave impulses providing finely divided fragmentation of uroliths in 97.4% cases. A mean Edose 49.2 J effectively destructs urinary concrements of any location with a minimal risk of postoperative complications. Maximal intensity regimes should be used carefully with consideration of a high risk of traumatic complications.
