目的 探讨经尿道切除技术（TUR）治疗下尿路疾病的适应证、操作方法、术中术后处理及并发症预防的要点。方法 应用经尿道汽化电切术（TURVP）和双极等离子汽化电切术（TUPKVP），分别以5％葡萄糖液和生理盐水作冲洗介质，选择性耻骨上膀胱造瘘，持续低压灌洗，术后气囊导尿管留置5～7天拔管，自行排尿。结果 经尿道前列腺双极等离子汽化电切术7例，经尿道前列腺汽化电切术58例，合计前列腺手术65例；腺性膀胱炎汽化电切术43例；膀胱肿瘤汽化电切术15例；后尿道狭窄等离子汽化电切术3例；精阜腺瘤汽化电切术2例。全部病例均一次手术完成，有效率（126／128）98．4％。无膀胱穿孔、电切综合征、大出血、真性尿失禁发生。前列腺术后尿道狭窄、排尿困难再次手术者2例，占3．08％，排尿疼痛、不适感6例，占9．23％，逆行射精4例，占6．15％。结论 TUR技术是一种微创、安全、迅速、有效、恢复快、并发症较少的腔内泌尿外科治疗方法，特别适用于下尿路疾病的手术；术中持续低压灌注对确保切割视野清晰、预防并发症至关重要。     

骨样骨瘤的影像学诊断:X线平片与CT常规横断位及MPR比较

目的:比较常规X线平片、多层螺旋CT常规横断位及多平面重组(multi-planar reformation,MPR)在骨样骨瘤诊断中的价值。方法:回顾性分析41例骨样骨瘤病人在X线平片、CT常规横断位及MPR图像上的表现及其对瘤巢及瘤巢内钙化显示能力。结果:41例病灶均表现为一圆形或卵圆形的透亮区,其周围有不同程度的骨质硬化。41例中仅8例在X线平片上能显示瘤巢,瘤巢显示率为19.5%(8/41);所有检查者均清楚显示瘤巢周围骨质硬化,但均不能显示瘤巢内钙化;41例CT横断位图像及MPR图像均能清楚显示瘤巢,18例CT横断位图像能显示瘤巢内钙化,30例病人在MPR图像能显示瘤巢内钙化;横断位CT图像和MPR对瘤巢内钙化显示率分别为43.9%(18/41)和73.2%(30/41)。结论:瘤巢是确诊骨样骨瘤的关键,CT是显示瘤巢的重要检查方法,MPR图像是显示瘤巢内钙化的最佳方法,有助于做出准确诊断。
