Ultrasonographic characterization of the urinary bladder in sows with and without urinary tract infection

Ultrasonographic assessment of dWT, vWT, WR and mWS of the urinary bladder of sows requires knowledge of bladder volume, and BD may be used as a volume equivalent. However, the parameters are inappropriate for the diagnosis of UTI as defined in this study, while moderate/high amounts of sediment seem to be indicative. Sediment can be visualized by transrectal scanning, but this is also possible using the transcutaneous route.
