[Frequency and risk factors for the development of infravesical obstructions caused by surgery of benign prostatic hyperplasia].

Benign prostatic hyperplasia (BPH) is one of the most common diseases of men elderly and senile age. The main surgical methods of treatment for BPH are transurethral resection and open prostatectomy. In some cases surgical treatment of BPH is accompanied by the development of postoperative complications leading to recurrence of the infravesical obstruction. Currently, there are no strict guidelines for selection of an optimal method of correction of late obstructive complications. This study highlights the main existing theories concerning development of urethral strictures and bladder neck contracture.
