目的 :评价前列腺移行区体积 (TZV)和移行区指数 (TZI)在诊断良性前列腺增生 (BPH)中的作用。方法 :采用经直肠超声测量 2 62例患者的前列腺体积 (TPV)和TZV ,其中A组 2 2 0例为有症状 ,未出现过尿潴留的BPH患者 ,B组 19例为反复出现尿潴留的BPH患者 ,对照组 2 3例为非BPH患者 ,并推算TZI(TZI =TZV/TPV)。以上患者同时接受了国际前列腺症状评分 (IPSS)、生活质量评分 (QOL)、最大尿流率 (Qmax)检查。所得数据进行统计学处理。结果 :A组、B组和对照组之间的TPV、TZV、TZI、IPSS、QOL、Qmax比较差异均有显著性意义 ,年龄与TPV和TZV有非常显著相关性 (分别r =0 .2 4,P <0 .0 1;r =0 .2 5 ,P <0 .0 1) ,与Qmax有非常显著负相关性 (r =- 0 .2 7,P <0 .0 1) ,与IPSS有显著相关性 (r =0 .15 ,P <0 .0 5 ) ,与QOL无相关性 (r =0 .11,P >0 .0 5 )。TPV与IPSS、QOL、Qmax有显著相关性 (r =0 .2 6,r =0 .2 0 ,r =- 0 .2 9,P均 <0 .0 5 ) ,而TZV和TZI与IPSS ,QOL ,Qmax均有非常显著相关性 (分别r =0 .40 ,r =0 .3 2 ,r =- 0 .43 ,P均 <0 .0 1;r =0 .5 1,r =0 .41,r =- 0 .5 2 ,均P <0 .0 1)。结论 :BPH患者随着年龄的增加 ,TPV、TZV、IPSS、QOL增加 ,Qmax减小。发生尿潴留的BPH患者 ,其TPV、TZV和TZI大于没有出现过?
Objective: To evaluate the role of TZV and TZI in the diagnosis of benign prostatic hyperplasia (BPH). Methods: Transrectal ultrasound was used to measure the prostate volume (TPV) and TZV in 626 patients. Among them, 220 patients in group A were symptomatic and had no urinary retention in BPH patients, and 19 patients in group B were recurrent urinary retention BPH patients, control group, 23 cases of non-BPH patients, and calculate TZI (TZI = TZV / TPV). The above patients also received IPSS, QOL and Qmax. The data obtained were statistically processed. Results: There were significant differences in TPV, TZV, TZI, IPSS, QOL and Qmax between group A and group B and the control group. There was a significant correlation between age and TPV and TZV (r = 0.24 , P <0. 01; r = 0. 25, P <0. 01) and had a significant negative correlation with Qmax (r = - 0.27, P < There was a significant correlation (r = 0.15, P <0.05), but no correlation with QOL (r = 0.11, P> 0.05). There was a significant correlation between TPV and IPSS, QOL and Qmax (r = 0.26, r = 0.20, r = -0.229, P <0.05) QOL and Qmax were significantly correlated (r = 0.40, r = 0.32, r = - 0.43, P <0.01; r = 0.51, r = 0 respectively. 41, r = - 0 .5 2, all P <0. Conclusion: With the increase of age, the TPV, TZV, IPSS, QOL increase and Qmax decrease in BPH patients. BPH patients with urinary retention, its TPV, TZV and TZI greater than never seen?
