The addition of pressure and flow rate recordings to conventional cystourethrography is relatively inexpensive in terms of cost and of radiologist's time, each investigation requiring approximately half an hour.The value of this investigation in males lies in assessing the severity and site of outlet obstruction, particularly when the prostate is not clinically enlarged. Its value in demonstrating detrusor instability in cases of obstruction and in patients with post-prostatectomy problems is discussed. It is essential to the adequate assessment of sphincter mechanisms in both males and females. The particular importance of this in the female lies in the poor results of routine surgery for incontinence where this is due to detrusor instability.Finally the importance in neurological patients of a urodynamic evaluation of continence mechanisms and voiding dysfunction, both as a preliminary assessment and as a guide to the efficacy of treatment, is outlined.Various criticisms of the technique are reviewed and appropriate rebuttals provided.
在传统膀胱尿道造影术中增加压力和流速记录，从成本和放射科医生的时间来看相对低廉，每次检查大约需要半小时。这项检查对男性的价值在于评估出口梗阻的严重程度和部位，尤其是在前列腺临床上未增大时。文中讨论了其在显示梗阻病例及前列腺切除术后患者逼尿肌不稳定方面的价值。这对于充分评估男性和女性的括约肌机制至关重要。在女性中，这一点尤为重要，因为当尿失禁是由逼尿肌不稳定引起时，常规手术效果不佳。最后概述了对神经疾病患者进行尿动力学评估控尿机制和排尿功能障碍的重要性，这既是初步评估，也是治疗效果的指导。文中回顾了对该技术的各种批评并给出了适当的反驳。
