Cystitis (inflammation of the bladder) is common in sows and is caused by a bacterial infection of the bladder. Bacteria usually reach the bladder by ascending the urethra, but may come from the kidneys. Most cystitis is caused by Escherichia coli. It travels up the urethra, particularly when the sow has not urinated for some time or when little urine is being produced because of low water intake. Lying in dirty conditions can also predispose the sow to cystitis.
