Transrectal ultrasonography was compared with voiding cystourethrography (VCU) in 27 patients after spinal cord injury. Both techniques gave clear images of the bladder and posterior urethra. Ureteric reflux, intraprostatic reflux and anterior urethral diverticula were seen only on VCU. Ultrasonography showed soft tissue detail and muscle contraction not seen on VCU. Other advantages of ultrasonography included the lack of radiation hazard, allowing prolonged observation; no contrast medium was required and this eliminated the need for catheterisation.
对27例脊髓损伤患者的经直肠超声检查与排尿性膀胱尿道造影（VCU）进行了比较。两种技术均能清晰显示膀胱和后尿道图像。输尿管反流、前列腺内反流和前尿道憩室仅在排尿性膀胱尿道造影中可见。超声检查显示了排尿性膀胱尿道造影中未见到的软组织细节和肌肉收缩情况。超声检查的其他优点包括无辐射危害，可进行长时间观察；无需使用造影剂，也无需插管。
