The measurement of residual urine volume by bladder catheterization causes quite some suffering to the patient and sometimes causes urinary tract infections. To evaluate the postoperative measurement of residual urine volume with a portable ultrasound bladder scanner (Bladder Scan BVI 3000) and the cost-benefit analysis as compared with postoperative catheterization we carried out a study on 30 patients with primary rectal cancer. The data were then compared with actual urine volumes. This was a prospective study dealing with the economical benefit of ultrasound scanning over catheterization during the hospital stay. The ultrasound bladder scanner was found to be a reliable method of estimating residual urine volume since its data correlated with actual volumes with a coefficient of 0.9. The results satisfied both physicians and patients. Ultrasound scanning of the bladder to measure residual urine volume reduced the frequency of catheterization by 38% as compared with the patients on intermittent catheterization, with 17.4 catheters saved for each patient. In conclusion, the ultrasound bladder scanner could protect patients from the discomfort and urethral injury which might have been caused by bladder catheters, thus decreasing medical expenses. This technique will play an important role in determining whether to conduct invasive urethral catheterization for postoperative urinary disturbance in rectal cancer.
通过膀胱导尿来测量残余尿量会给患者带来相当大的痛苦，有时还会引发尿路感染。为了评估使用便携式超声膀胱扫描仪（膀胱扫描BVI 3000）进行术后残余尿量测量以及与术后导尿相比的成本效益分析，我们对30例原发性直肠癌患者进行了一项研究。然后将数据与实际尿量进行比较。这是一项关于住院期间超声扫描相对于导尿的经济效益的前瞻性研究。发现超声膀胱扫描仪是一种可靠的估计残余尿量的方法，因为其数据与实际尿量的相关系数为0.9。结果令医生和患者都满意。与间歇性导尿的患者相比，通过超声扫描膀胱来测量残余尿量使导尿频率降低了38%，每位患者节省了17.4次导尿。总之，超声膀胱扫描仪可以使患者免受膀胱导管可能造成的不适和尿道损伤，从而降低医疗费用。这项技术在确定是否对直肠癌术后尿路紊乱进行侵入性尿道导尿方面将发挥重要作用。
