[Titanium-nickel alloy stand for urethrostenosis caused by prostatauxe].
Self-made spiral tubular stand of titanium-nickel alloy, characterized by shape memory effect and good biocompatibility, was used in 15 patients with urethro-stenosis caused by prostatauxe. Of these patients, 14 restored normal urination and 1 failed because of technical problems. With the shape memory feature of titanium-nickel alloy, the stand may be easily inserted and long-term set in the prostatic urethra. This safe, simple method is particularly suitable to the aged patients.
