[The efficacy of portable 3-dimensional ultrasound scanning device (Bladder Scan BVI6100) for measurement of residual urine volume--comparison with transabdominal ultrasound estimation].
In 177 patients, we evaluated the efficacy of a portable 3-dimensional ultrasound scanning device (Bladder Scan BVI6100) in measurement for residual urine volume, compared with transabdominal ultrasound estimation, using values measured by urethral catheterization as actual values. A high correlation was demonstrated between values measured by BVI6100 and actual values. Error rates of the values measured by BVI6100 male mode, female mode and transabdominal ultrasound estimation to actual values were 42.7 +/- 32.6, 50.6 +/- 63.3 and 65.8 +/- 43.7%, respectively. The error rate of the values measured by BVI6100 female mode was significantly higher than that by BVI6100 male mode or transabdominal ultrasound estimation. Irrespective of patient sex, the error rate of the values measured by BVI6100 in male mode was significantly lower than that in female mode. Therefore, BVI6100 male mode was considered to be a useful alternative for measurement of residual urine with accuracy similar to that of transabdominal ultrasound estimation.
