Symptoms of urinary calculus


Urinary concrements are stone formations in the area of ​​the urinary organs, especially the kidneys and pelvis.

Disease origin and development

One possible cause for the formation of urinary calculus is inflammation of the urinary organs with a change in the pH value. This leads to the formation of crystallization nuclei. Another possibility is concentration due to lack of water, especially with dry feeding. Furthermore, there may be a vitamin A deficiency or the dog has a genetically determined metabolic abnormality or a viral infection.

Clinical picture – symptoms

Symptoms depend on the location, size, and number of the stones. Bladder stones make it difficult and painful to urinate (dysuria) with terminal hematuria (blood in the urine). Renal pelvic stones, on the other hand, lead to hematuria of the entire urine. The painful need to urinate is particularly noticeable. The dog tries to urinate constantly.


The prognosis is strongly dependent on the location of the stones. If the urethra closes completely, it can lead to severe urethral and bladder damage. This can trigger a bilateral increase in pressure in the renal pelvis, which results in fatal urine poisoning. The earlier the urinary tract disease is treated, the better the prognosis. If you suspect that your animal has a urinary tract disease, you should consult a veterinarian as soon as possible.
