Objective To assess whether recovery of urinary continence after laparoscopic radical prostatectomy is associated with membranous urethral length on preoperative magnetic resonance imaging.Methods 86 cases with pathologic confirmed prostate carcinoma were performed laparoscopic by a signal surgeon.Patients were categorized into two groups according to membranous urethral length(MUL) on preoperative magnetic resonance imaging(Group A: MUL ＜ 14mm;Group B: MUL ＞ 14mm), and MUL was measured on coronal images as the distance from the prostatic apex to the entry of the urethra into the penile bulb.After surgery we recorded and analyzed recovery of urinary continence of patients at least one year.Results In the 86 patients who underwent MRI preoperatively mean membranous urethral length was 14.8(10.2-24.3)mm.Three months after surgery, group A had 79.2％ and group B had 47.4％ were completely continent (p=0.016).Six months after surgery continence rate was 87.5 ％ and 71.1％ , one year was 93.8 ％ and 89.5 ％ for group A and B separately.There was a significant difference between group A and group B in the urinary continence curve (p=0.039).

目的:研究中青年男性运动与勃起功能之间的关系.方法:在三所医院泌尿外科门诊就诊的中青年男性患者或男性陪人,在征得同意后独立完成巴芬伯格运动量表及IIEF-15量表.按照巴芬伯格量表量化的运动量将患者分为两组,静坐组:运动消耗能量≤ 1400Kcal/周及运动组:运动能量消耗＞1400Kcal/周.结果:静坐组(65例,平均年龄35.9±4.7岁)总IIEF评分为54.4分,运动组(85例,平均年龄
辅助生殖技术和男性不育显微外科的发展给男性不育症的治疗带来了新希望.随着对男性不育症病因的深入认识,超过70％男性不育症患者可通过显微手术联合辅助生殖技术获得治疗.2004年,Philip S.Li等在中国报道了显微外科治疗梗阻性无精子症的新进展.2007年以来,我院先后多名医生去美国康纳尔大学进修学习男性不育显微外科技术,很大程度上加速在我院男性显微外科手术的发展及成熟.本文通过回顾性分析我院男
输精管附睾吻合术(Vasoepididymostomy, VE)是显微手术中最具有挑战性的手术,通常采用双头针的线进行缝合.尽管单针使用在动物研究中有报告,但在人体上报告非常少,而且例数都很少.为此,我们进行本研究.在本研究中,我们通过总结使用单头针(single-arm)纵向双针套叠缝合的方法进行手术的患者的数据,评估本手术方法的有效性和安全性以及预后和复通率的影响因素.从2012年7月至201
