磁共振成像在阴茎假体植入术治疗ED后的应用

目的 探讨磁共振成像技术在阴茎假体植入术治疗ED随访中的应用。方法 对ED患者进行阴茎充吸试验通过MRI对试验前后植入假体勃起前后的长度，管腔内径进行测量，观察储液球及管道有否渗漏、脱节，有否术后感染造成局部软组织粘连。结果 本文2例患者分别于术后8个月，1年行MR复查，轴位T2WI上可见阴茎假体外周有环形假包膜信号假体与周围软组织层次分界清晰，未见明显渗漏信号，膀胱前方见储液囊，形态张力良好，阴囊内见松开阀信号，充胀过程顺利，假体通畅。结论 磁共振成像技术具有良好的软组织分辨率，与现有X线平片、B超检查相比更能提供准确、清晰的影像诊断像据，在阴茎假体值入术治疗ED中具有良好的应用价值。

Application of MRI after inflatable penile prosthesis implantation for erectile dysfunction

Objective To probe role of MRI in follow-up of inflatable penileprosthesis(IPP) implantation for treatment of erectile dysfunction (ED). MethodsMRI was used to measure length and inside diameter of the dildo before and aftererection after inflation-deflation experiment. Leakage, dislocation, soft tissue adhesiondue to postoperation infection were observed for liquid-storing ball and duct. Results2 patients undergoing IPPP were followed up with MRI at 8 months and 12 months.Axis-position T2WI showed ring-shaped pseudocapsule around the IPP, borderbetween IPP and surrounding soft tissue was clear, there was no leakage signal,liquid-storing cyst was seen ahead of bladder, the cyst stayed good in shape and tension,signal for turning-off valve can be seen in scrotum. The inflation and deflation weresmooth and the IPP was unobstructed. Conclusion MIR is good at telling softtissues, and better in imaging compared to X-ray and B ultrasound. MRI is useful infollow-up of IPP implantation for treatment of ED.[
