One of urodynamic diagnostic methods is visualisation of the bladder neck opening which enables seeing the difference between internal and external urethral sphincter disfunction. Micturition video cysto-urethrography with X-rays makes possible to carry on such examinations, but it requires catheterisation which makes the method invasive. My purpose is to replace this examination by dynamic functional evaluation of the internal urethral sphincter during transrectal ultrasonography. During 10 routine transrectal ultrasound examinations of the prostate, patients were asked to urinate. During examination changes in configuration of the bladder neck and prostatic urethra were observed. Two patients could not urinate in horizontal position. In the rest of the patients very clear pictures showing changes in the shape and dimensions of the urethra during urination, were achieved. They were much more clear in comparison with X-ray video cystourethrography. Transrectal sonography is a perfect technique of the visualisation of the bladder neck and prostatic urethra during urination. The suggested method should be included into the urodynamic examinations.
尿动力学诊断方法之一是膀胱颈开口可视化，这有助于区分尿道内括约肌和外括约肌功能障碍。借助X射线的排尿视频膀胱尿道造影术能够进行此类检查，但它需要插入导管，这使得该方法具有侵入性。我的目的是通过经直肠超声检查期间对尿道内括约肌进行动态功能评估来取代这项检查。在对前列腺进行10次常规经直肠超声检查时，要求患者排尿。检查过程中观察到膀胱颈和前列腺尿道形态的变化。两名患者无法在水平位置排尿。在其余患者中，获得了非常清晰的排尿时尿道形状和尺寸变化的图像。与X射线视频膀胱尿道造影术相比，这些图像要清晰得多。经直肠超声检查是排尿期间膀胱颈和前列腺尿道可视化的完美技术。建议的方法应纳入尿动力学检查。
