title: The reliability of transabdominal ultrasound scanning in the determination of prostatic volume. An autopsy study.
abstract: The prostatic volume as determined by transabdominal ultrasound scanning using the ellipsoid method was compared to the prostatic volume determined by autopsy in 26 post-mortem men. The regression line was nearly optimal (Y = 1.06 chi + 0.57) although it seems that ultrasound underestimates prostatic volume slightly. The parametrical correlation coefficient was 0.86 and the non-parametrical Spearmans rho was 0.76. It is concluded that transabdominal ultrasound scanning has a definite value in the assessment of prostatic size.
