绿激光光气化术治疗良性前列腺增生

Photoselective vaporization of the prostate for the treatment of benign prostatic hyperplasia

目的 探讨前列腺选择性光气化术（PVP）治疗良性前列腺增生（BPH）的疗效与安全性。方法 应用平均功率80W、峰值功率280W的高功率KTP激光行PVP治疗有梗阻症状的BPH216例（前列腺体积24-134g，50g以上78例）。结果 手术时间30～120min。121例留置导尿管0～24h后均能自行排尿。186例术后随访1～3个月，国际前列腺症状评分（I-PSS）由26．0±3．7下降至13．4±1．9，（P〈0．01），最大尿流率（Qmax）由（6．82±2．47）ml／s上升至（17．23±4．78）ml／s，（P〈0．01）。术后继发出血4例，尿路感染6例，急性附睾炎1例。结论 PVP治疗BPH操作简单，安全、有效，侵袭性小、康复快，是治疗BPH较为理想的微创手术方法。

Objective To study the efficacy and safety of photoselective vaporization of the prostate for the treatment of benign prostatic hyperplasia. Methods A total of 216 men（56 to 93 years old） with lower urinary tract symptoms secondary to benign prostatic hyperplasia received photoselective vaporization of the prostate with an 80W quasicontinuous KTP laser. Prostatic volume was 24- 134 g. Results Mean operative time was 48.8 min. After the cathetre was pulled out in 24 hours, the patients could generally urinate well. At one-month follow-up, the mean I-PSS decreased from 26±3. 7 to 13. 4±1.9（P〈0.01） ,whole the Qmax increased from （6.82±2. 47） ml/s to （17.23±4. 78） ml/s （P〈0. 01）. Complications consisted of hematuria in 4 cases, urinary infection in 6 cases and 1 acute epididymitis. Condusion PVP is a safe, effective and simple procedure for the treatment of BPH with less pain and quick recovery.
