ABSTRACT
Objective To evaluate the effectiveness of Nicked-Titanium Shape-Memory alloy net-like stent in the treatment of high risk patients with benign prostatic hyperplasia Methods 35 high risk patients with benign prostatic hyperplasia were treated with Nicked-Titanium Shape-Memory alloy net-like stent from 1995 to 1998. The results were analyzed retrospectirely. Results 34 cases of the disease were treated successfully at the first session, 30 of whom could urinate immediately after treated. 4 patients had a normal urination in 3 days after operation, the total efficacy rate being 97.1% (34/35). Conclusions The present study shows that Nickel-Titanium Shape-Memory alloy net-like stent for patients with benign prostatic hyperplasia is a safe, efficient and ideal method. The long term efficacy of the stent is in progress.
