[Therapy of bladder calculi--trends and results of a mainly transurethral oriented clinic].

From 1975 to 1985 519 patients with urinary calculi were treated in the Urologic Clinic of the Berlin-Buch Hospitals. 57.6% of them were treated by lithotripsy and TUR-P, 14.8% by lithotripsy alone, 11.8% by stone removal and transvesical adenomectomy and 15.8% by suprapubic cystotomy only. The diagnosis of the four forms of therapy is described. The trend in the conception of treatment goes to the treatment of calculi transurethrally in combination with the simultaneous removal of the obstruction of the outflow from the urinary bladder. Since October 1985 the electrohydraulic lithotripsy has been used. Up to 1985 in 218 patients urinary calculi were crushed by means of the device Urat-1. In 190 patients (87.3%) the lithotripsy was carried out in combination with other therapeutic measures, in 153 (70.2%) a transurethral resection of the prostate gland and in 28 patients (12.9%) other transurethral interventions were performed. Postoperatively, in 7 patients complications occurred (3.2%), perforations of the urinary bladder were not seen. Taking into consideration the whole number of patients, it is reported on the advantages of the use of the electrohydraulic lithotripsy by means of the apparatus Urat-1 as an uncomplicated technique easily to be learned, which excellently may be combined with simultaneous transurethral interventions.
