目的　探讨国产前列腺内支架治疗前列腺增生引起排尿困难的临床疗效。方法　 3 2例前列腺增生引起排尿困难的患者 ,置入 3 5枚前列腺内支架。支架均为国产镍钛记忆合金编织而成。结果　 3 2例均一次治疗成功 ,2 8例置入支架后立即自行排尿 ,3例因前列腺增生过大 ,前列腺尿道部过长 ,置入 1个支架 ,排尿仍有困难 ,再次置入第 2个支架后 ,立即自行排尿 ,1例伴有糖尿病的患者 ,置入支架 1周后排尿困难未改善 ,而进行外科手术治疗。 2 8例生活质量积分 0～ 3分 ,19例术后随访 6～ 18个月 ,国际前列腺症状评分 (I PSS)术前 2 7.5 9± 4.11,术后 6.93± 3 .76(P <0 .0 0 1) ,最大尿流率术前 (1.79± 3 .89)ml/s,术后 (14 .2 5± 3 .65 )ml/s(P <0 .0 0 1)。结论　前列腺支架治疗前列腺增生引起的排尿困难是可靠的。

Application of Homemade Stents in Prostatic Hypertrophy Therapy

Objective To explore the clinical effect of homemade prostate stent on treating dysuria caused by prostatic hypertrophy. Methods Thirty-five homemade prostate stents were implanted into 32 patients who suffered from dysuria caused by prostatic hypertrophy. Results The treatments were all successful with one operation in 32 patients. Twenty-eight patients urinated by themselves immediately after stenting. Because of the oversize prostatic hypertrophy,the dysuria of 3 patients were not apparently improved after implanting one stent. When another stent was inserted,patients urinated by themselves immediately. In 1 patient who suffered from diabetes,the surgery was performed because the condition of dysuria was not improved one week after stenting. Twenty-eight cases living quality score were 0-3. Nineteen cases followed-up for 6-16 months,and the resulte showed that the IPSS were 27.59±4.11 and 6.93±3.76 (P<0.001) respectively before and after stenting. PUFR were (1.79±3.89) ml/s and (14.25±3.65) ml/s (P<0.001) respectively before and after stenting. Conclusion To apply the prostate stents in prostatic hypertrophy was safety.
