Electrohydraulic lithotripsy with aspiration of the fragments under vision--304 consecutive cases

We herein report on 304 consecutive cases of bladder stones treated by electrohydraulic lithotripsy. The special armamentarium is described. The average age for male patients was 68.5 years, the oldest being 102 years, and for female patients it was 63.9 years. Of the patients 38.5 per cent were high risk. The weight of the transurethrally removed stones ranged from 1 to 135 gm. In 70.4 per cent of the male patients transurethral resection of the prostate was done under the same anesthesia and technical problems were encountered in 12 operations (4 per cent). Bladder perforations occurred in 5 patients but cystotomy and drainage were necessary in only 1 (0.3 per cent).
