目的 探讨国际前列腺症状评分(IPSS)与尿动力学检查非压力-流率(P-F)指标评估经耻骨后前列腺切除术(RPP)治疗良性前列腺增生症(BPH)疗效的可能性。方法 选择189例良性前列腺增生患者,对其IPSS及选定的尿动力学指标在术后疗效满意组(SG)与不满意组(DG)间进行比较并分析其特点。结果 189例患者中,对手术疗效满意132例,占69.84％;对疗效不满意57例,占31.10％。全部患者均经术前IPSS询问及术前尿动力学检查,获最大尿流率(Qmax)值104例,其中测得最大尿流率时膀胱逼尿肌压力(Pdet,Qmax)者85例,其余85例未能测得Qmax及Pdet,Qmax值者接受RPP手术。SG与DG的IPSS均数分别为24.65+6.932与26.75+8.804(P>0.05).Qmax均数分别为33.95+2.743 ml/s与1.71+0.402 ml/s(P<0.05),Pdet,Qmax均数分别为86.96+41.955cmH2O与35.64+19.966 cmH2O(P<0.05)。结论 IPSS不能作为评估RPP术治疗BPH疗效的依据;尿动力学非P-F指标中,Qmax>2 ml/s及Pdet,Qmax>50 cmH2O可作为评估RPP术后疗效的依据。
Objective To investigate the possibility of evaluating the curative effect of transrectal prostatectomy (RPP) on benign prostatic hyperplasia (BPH) by using International Prostate Symptom Score (IPSS) and urodynamics non-pressure-flow rate (P-F) Methods A total of 189 patients with benign prostatic hyperplasia (BPH) were selected and their IPSS and selected urodynamic parameters were compared between the satisfactory group (SG) and the unsatisfactory group (DG) after operation and their characteristics were analyzed. Results Of the 189 patients, 132 were satisfied with the operation, accounting for 69.84%; 57 were not satisfied with the effect, accounting for 31.10%. All patients underwent preoperative IPSS examination and preoperative urodynamic examination, the maximum flow rate (Qmax) value of 104 cases, of which measured the maximum urinary flow rate of detrusor pressure (Pdet, Qmax) in 85 cases, The remaining 85 patients who failed to measure Qmax and Pdet, Qmax received RPP. The mean IPSS of SG and DG were 24.65 + 6.932 and 26.75 + 8.804, respectively (P> 0.05) .The mean Qmax were 33.95 + 2.743 ml / s and 1.71 + 0.402 ml / s respectively The numbers were 86.96 + 41.955 cmH2O and 35.64 + 19.966 cmH2O, respectively (P <0.05). Conclusions IPSS can not be used as a basis for assessing the efficacy of RPP in the treatment of BPH. Qmax> 2 ml / s and Pdet, Qmax> 50 cmH2O in urodynamic non-P-F can be used as the basis for assessing the efficacy of RPP.
