Description

A condition of the urinary system, caused by dehydration, decreased urine volume or fluid flow rates, or increased excretion of minerals such as calcium, oxalate, magnesium, cystine, and phosphate. This condition is characterised by urinary calculi located in the lower urinary tract (urinary bladder and urethra). This condition may also present with haematuria, dysuria, or pain in the flank, lower abdomen, or groin. Confirmation is by abdominal radiography to determine the presence and location of calculi.
