To evaluate the efficacy of transrectal real-time gray-scale sonographic voiding cystourethrography in patients with neuromuscular dysfunction of the bladder, 32 men suspected of having neuromuscular dysfunction each underwent sonographic and radiographic voiding cystourethrography and urodynamic studies. The benefits accruing from the sonographic study included: (1) patients received no radiation; (2) it was as diagnostic as, and sometimes more diagnostic than, the radiographic study; (3) drug effects were easily studied; (4) accurate measurements of urethral length could be obtained; and (5) prostate diseases that might affect these patients were visible, such as benign prostatic hyperplasia, prostatic carcinoma; and prostatic calculi. In addition, sonography made one new observation possible: The seminal vesicles were enlarged in 10 patients receiving the alpha-adrenergic blocker, phenoxybenzamine. This enlargement may cause sterility.
为评估经直肠实时灰阶超声排尿膀胱尿道造影术对膀胱神经肌肉功能障碍患者的疗效，32名疑似患有神经肌肉功能障碍的男性患者分别接受了超声和放射学排尿膀胱尿道造影术以及尿动力学检查。超声检查的益处包括：（1）患者无需接受辐射；（2）其诊断效果与放射学检查相当，有时甚至更具诊断价值；（3）便于研究药物效果；（4）能够准确测量尿道长度；（5）可以观察到可能影响这些患者的前列腺疾病，如良性前列腺增生、前列腺癌和前列腺结石。此外，超声检查还带来了一项新的观察结果：10名接受α-肾上腺素能阻滞剂苯苄胺治疗的患者精囊增大。这种增大可能导致不育。
