Bladder Stones (Cystic Calculi)

Calculi, popularly called stones can develop in many cavities in the body, e.g. the gall bladder and kidneys.
Common problems associated with bladder stones are;
– Blood stained urine (haematuria)
– Straining to urinate (dysuria)
These problems are not unique with bladder stones. They are also the common symptoms of cystitis.
Haematuria occurs due to the irritation caused by the stones on the delicate lining of the bladder. This causes inflammation and then bleeding from the surface.  Bacterial infection also exacerbates the
problem. Dysuria can occur due to inflammation and irritation of the bladder wall, creating an urge to pass urine. Dysuria can also result from blockage by the stones. When urine flow from the bladder is
obstructed the bladder continues to fill with urine and this is an acutely painful condition. Often just touching the dog on the abdomen will cause cries of pain. Urethral blockage is particularly serious in
male dogs since the long narrow urethra passes through the penis and blocks easily. Bitches with a much shorter urethra can frequently pass the stones which are causing the blockage after a period of
discomfort and sometimes dysuria.
The signs of Cystic Calculi are haematuria and dysuria , as
discussed, these are basically the signs of cystitis, therefore a
definite diagnosis of bladder stones depends on other signs and tests which include:
Urine analysis and examination of a sample for stones or crystals
Larger stones can sometimes be palpated (felt) through the abdominal wall.
Most, but not all, bladder stones can be visualised with
Treatment, if the stones cause obstruction, is an emergency and usually involves surgery.
