ULTRASONIC LOCALIZATION OF NORMAL MALE RAT PROSTATE AND URINARY BLADDER

Abstract

We studied the localization of the prostate and the urinary bladder in normal male Wistar rats by ultrasound.
The prostate was located in the middle and slightly to the dorsal side of the pelvic cavity on the transverse and longitudinal planes. It showed an isoechoic sonogram.
The urinary bladder was located cranial to the prostate on the longitudinal plane and in the middle of the pelvic cavity. It was identified easily and showed a cystic pattern. The seminal vesicles were located to the right and left of the urinary bladder and showed cystic patterns.
Ultrasound was thought to be useful for the identification of these structures.
