目的对直肠超声引导下无水乙醇注射治疗前列腺增生进行疗效评价。方法对42例因前列腺增生导致反复尿潴留患者行直肠超声引导下无水乙醇注射治疗,并于术前,术后3个月,6个月对最大尿流率,前列腺体积,国际前列腺症状评分(IPSS),残余尿进行测定。结果治疗后6个月,最大尿流率由术前无自主排尿提高到(13.2±3.9)m l/s,前列腺体积为(54.2±5.3)m l缩小至(40.5±4.2)m l(P<0.01),国际前列腺症状评分由术前的(29.8±3.0)分下降为(8.0±2.8)分(P<0.01),残余尿由术前的(140±50)m l降为(36.2±13.5)m l(P<0.01)。结论经直肠超声引导下注射无水乙醇治疗前列腺增生简便易行,疗效显著且并发症少,尤其适用于不能耐受手术或拒绝手术者。
Objective To evaluate the efficacy of absolute ethanol injection in the treatment of benign prostatic hyperplasia under the guidance of rectal ultrasound. Methods 42 cases of patients with recurrent urinary retention caused by benign prostatic hyperplasia underwent rectal ultrasound guided ethanol injection, and in the preoperative and postoperative 3 months, 6 months, the maximum urinary flow rate, prostate volume, the International Prostate Symptom Score (IPSS), residual urine was measured. Results After 6 months of treatment, the maximal uroflow rate was increased from (13.2 ± 3.9) ml / s to (13.2 ± 3.9) ml and from (54.2 ± 5.3) ml to (40.5 ± 4.2) ml (P <0.01) , The international prostate symptom score decreased from (29.8 ± 3.0) points to (8.0 ± 2.8) points before surgery (P <0.01), and the residual urine decreased from (140 ± 50) ml to (36.2 ± 13.5) ml P <0.01). Conclusion Under the guidance of rectal ultrasound, the injection of absolute ethanol is an effective and convenient method for the treatment of benign prostatic hyperplasia with significant curative effect and few complications. It is especially suitable for patients who can not tolerate surgery or refuse surgery.
