Urinary obstruction in dogs and cats is a very common complication in the veterinary routine, being triggered, mainly, by calculations or tumors that prevent the elimination of urine through the urethra. The main symptom that animals with this problem present is that of looking for the usual place of needs over and over again, eliminating very small amounts of urine or not urinating - making only a kind of micturition of micturition.
With the existence of urinary obstruction in dogs and cats, elimination of the urine produced does not occur properly, causing a distension of the bladder, of the animal - which generates sensitivity (pain) and a great abdominal discomfort.
Due to the large volume of urine inside the bladder (without the possibility of total or partial exit), substances that should be eliminated by the body are removed, which can cause toxic effects to the organs. In addition to this condition increasing the chance that urine accumulates in the kidneys, due to excess, it can also cause the atrophy of internal structures in the region; dilating its wall (generating the renal alteration known as hydronephrosis) and causing renal and circulatory impairment, in case the bladder tension is not resolved.
Cats with urinary obstruction, due to the excessive elevation of blood potassium levels (hyperkalaemia) in the blood, they may have changes in the electrical activity of the heart (arrhythmias); that can lead the animal to death when not treated. Aggravating factors such as hypocalcemia (decrease in blood calcium), hypothermia (drop in temperature), uremia (accumulation of urea in the blood), acidosis (decrease in blood pH), hypovolemia (decrease in blood volume) and hyperphosphatemia (increase in phosphorus) can increase the instability of the condition - further increasing the chances of the feline dying.
Stones or stones present in kidneys or bladder, urethra obstructed by inflammation, infection, trauma and neoplasms are considered the main obstructive causes of urinary tract; and, in cats, in addition to the reasons mentioned, psychological stress is also noted as causing the complication: it forms crystals in the urine, which can occlude its usual leakage.

The intervention to solve the problem must be carried out by the veterinarian who works with intensive care, both before and after the unblocking process (by means of urethral probe or surgical procedure) - the hospitalization of the animal is recommended for adequate recovery of the kidneys and monitoring of the urinary condition.
The performance of imaging tests (including radiography, ultrasound and tomography), blood tests (such as blood count, electrolytes, renal profile and blood gas analysis, among others), administration of drug treatments (anti-inflammatory, antibiotics, analgesics) and / or surgery for manual removal of the obstructive reason or deviation of the urinary canal (cases where the necrosis of the penis occurs due to the lack of local blood circulation) may also be part of the procedures to remedy the complication.
Therefore, when noticing unusual urinary behavior in your pet - may or may not add up with decreased appetite, apathy, abnormal breathing, vomiting, dehydration and / or comatose state - seek a veterinary hospital as soon as possible, because, in addition to being suffering from abdominal pain and widespread consequences of this complication, the animal is also at risk of dying if not treated in time.
It is important to remember that the best treatments for urinary obstruction in dogs and cats are associated with early care and, therefore, stay connected in three steps so that the care of the pet is as effective as possible and he can recover well and quickly:
- Observe carefully if there is an increase in demand for the urination site, involving the presence of force or lack of urine in attempts
- Check the amount of urine expelled by the animal (if it is the usual or not)
- If the pet is unable to urinate (or very small amount of pee and only through great efforts), suspend the water and the animal's food, immediately, and look for a trusted veterinarian - so that the necessary procedures are performed and, in the most intense cases, surgeries
