In patients with symptoms suggestive of bladder outflow obstruction and a free flow rate less than 12 ml/s a visual analogue scale was used to measure the response to the question "Compared to 5 years ago, how thick is your stream when you pass urine?". The visual analogue scale compared favourably with cystometry in distinguishing between low flow rates resulting from impaired detrusor contractility and low flow rates due to bladder outflow obstruction. A visual analogue scale may serve to alert the surgeon to the presence of impaired detrusor contractility and the need for a fuller urodynamic assessment in patients with a low urinary flow rate prior to consideration for prostatectomy.
对于有膀胱出口梗阻症状且自由尿流率低于12毫升/秒的患者，使用视觉模拟评分法来测量对“与5年前相比，你排尿时尿流有多粗？”这一问题的回答。在区分因逼尿肌收缩功能受损导致的低尿流率和因膀胱出口梗阻导致的低尿流率方面，视觉模拟评分法与膀胱测压法相比效果良好。视觉模拟评分法可能有助于提醒外科医生，对于尿流率低且在考虑前列腺切除术前的患者，存在逼尿肌收缩功能受损的情况以及进行更全面尿动力学评估的必要性。
