[Extracorporeal shock-wave lithotripsy of bladder stones in patients with benign prostatic hyperplasia]

In urological department of Moscow Regional Research Clinical Institute, extracorporeal shock-wave lithotripsy (ECSWL) or bladder stones in patients with benign prostatic hyperplasia (BPH) has been made prior to TUR from 1991. This treatment was given to 52 patients aged 54-79 years with prostatic volume 40-120 cm3. Complete or partial fragmentation of the vesical calculi was achieved after 1 to 3 ECSWL sessions (a total of 105 sessions, 2000-3000 impulses a session). Pretreatment with ECSWL of bladder stones significantly facilitates TUR in BPH patients with vesical calculi of big size (2.5 cm and more in diameter). Extracorporeal fragmentation of large stones prior to TUR makes surgery of such patients less traumatic and reduces the risk of intraoperative complications compared to endoscopic cystolithotripsy or cystolithotomy. ECSWL of cystolithes expands indications for drug therapy or thermal non-endoscopic BPH treatment in aged patients with poor somatic status and in young sexually active males rejecting surgery.
