摘要: 本文分析经直肠三维超声与应变力弹性成像对老年患者前列腺癌术后膀胱出口畅通度的诊断价值。选取130例老年前列腺癌患者作为研究对象,根据术后膀胱出口畅通度分为对照组与研究组,各65例。所有患者均进行经直肠三维超声、应变力弹性成像检查及尿动力学检查。结果显示,研究组患者的最大膀胱灌注量、最大尿流率(Qmax)测定值低于对照组患者(P<0.05),研究组患者的残余尿量(PVR)、最大逼尿肌压力(Pdetmax)、超声测量膀胱质量(UEBW)、最大弹性评分、动脉阻力指数、移行带指数、突入指数高于对照组患者(P<0.05)。与经直肠三维超声、应变力弹性成像单项诊断相比,两项联合对老年前列腺癌术后膀胱出口畅通度诊断价值较高,曲线下面积(AUC)为0.868(P<0.05)。经直肠三维超声与应变力弹性成像在老年患者前列腺癌术后膀胱出口畅通度的诊断中具有较高价值。

Abstract: This paper analyzed the diagnostic value of transrectal three-dimensional ultrasound and strain elastography for bladder outlet patency in elderly patients after prostatectomy. 130 elderly patients with prostate cancer were selected as the research object. According to the postoperative bladder outlet patency, they were divided into control group and study group, with 65 cases in each group. All patients underwent transrectal three-dimensional ultrasound, strain elastography and urodynamic examination. The results showed that the measured values of maximum bladder perfusion volume and maximum urinary flow rate (Qmax) in the study group were lower than those in the control group (P<0.05). The postvoid residual ruine (PVR), maximum detrusor pressure (Pdetmax), ultrasound measured bladder weight (UEBW), maximum elasticity score, arterial resistance index, transitional zone index and inrush index in the study group were higher than those in the control group (P<0.05). Compared with the single diagnosis of transrectal three-dimensional ultrasound and strain force elastography, the combination of the two has a higher diagnostic value for bladder outlet patency in elderly patients with prostate cancer,the area under the curve (AUC) was 0.868 (P<0.05). Transrectal three-dimensional ultrasound and strain elastography have a high value in the diagnosis of bladder outlet patency after prostatectomy in the elderly patients.
