目的:探讨分析术前移行带指数（TZI）对经尿道前列腺电切术（TURP）患者疗效的影响。方法:对贵州省人民医院2016年1月至2018年9月收治的206例行TURP患者进行回顾性分析，术前均行经直肠超声（TRUS）检查测定前列腺体积（TPV）及移行带体积（TZV），根据移行带指数（TZV/TPV）大小，分为A组（TZI0.05），B组TPV（74.57±29.25）ml明显大于A组（46.25±24.56）ml，n P<0.001。比较两组术后随访结果，IPSS-s（n P=0.079）、QOL（n P=0.71）、PVR（n P=0.651）差异无统计学意义，但术后IPSS、IPSS-v、Qmax[A组：B组（8.50±5.75）与（6.38±4.36），（4.03±3.75）与（2.63±2.5），（16.54±4.43）ml/s与（18.94±4.84）ml/s，均n P<0.05]，组间差异均有统计学意义。（2）不论是A组还是B组，患者术后IPSS、IPSS-v、IPSS-s、QOL、Qmax及PVR与术前分别比较均差异有统计学意义（均n P<0.01）。（3）Pearson直线相关性分析发现TZI与△Qmax（n r=0.32，n P<0.01）间存在显著正相关，与%IPSS（n r=-0.22，n P<0.01）间存在较弱的负相关性，而TZI与△QOL（n r=0.08，n P=0.238）间不存在相关性。n 结论:TURP疗效与TZI可能存在一定相关性，且TZI≥0.5的患者，TURP疗效可能更好。“,”Objective:To investgate the effect of properative transitional zone index (TZI) on the outcome of transurethral resection of prostate (TURP).Methods:A retrospective analysis was performed on 206 patients with TURP who were admitted to our hospital from January 2016 to September 2018. All patients underwent transrectal ultrasound (TRUS) to determine the total prostate volume (TPV) and the transition zone volume (TZV). Patients were divided into two groups according to TZI (TZV/TPV) (group A: TZI0.05). However, the TPV of patients in group B (74.57±29.25) ml was significantly larger than that in group A (46.25±24.56) ml, n P<0.001. While the postoperative follow-up outcomes of the two groups were compared, we found that IPSS-s (n P=0.079), QOL (n P=0.710), and PVR (n P=0.651) were not statistically different between the two groups, but the postoperative IPSS, IPSS-v, and Qmax (8.50±5.75 vs 6.38±4.36, 4.03±3.75 vs 2.63±2.5, and (16.54±4.43) ml/s vs (18.94±4.84) ml/s, all n P<0.05) were significantly different between the two groups. 2. Postoperative IPSS, IPSS-v, IPSS-s, QOL, Qmax and PVR were significantly different from those before surgery in two groups, respectively. 3. Pearson linear correlation analysis showed a significant positive correlation between TZI and ΔQmax ( n r=0.32, n P<0.01), a weaker negative correlation between TZI and %IPSS (n r=-0.22, n P<0.01), and no correlation between TZI and ΔQOL ( n r=0.08, n P=0.238).n Conclusion:There may be a correlation between the outcome of TURP and TZI, and the outcome of TURP may be better in patients with TZI ≥ 0.5.
