Oliguria and anuria are medical emergencies that require immediate treatment. If left untreated, these conditions can lead to death within hours or days. Proper treatment is dependent upon the cause of the condition. Renal hypoperfusion, if present, needs to be corrected by intravenous (IV) administration of a normal saline solution or similar fluid. Once the renal hypoperfusion is corrected, a diuretic medication to encourage urine production and flow may be prescribed. Is there is an obstruction in the urinary tract, such as abnormal tissue growth in the form of a neoplasm (tumor), this will need to be removed.
In cases of primary oliguria and anuria, treatment is limited to addressing the symptoms and supporting the patient long enough for spontaneous recovery of kidney function to occur. Elimination of causative factors may stop or slow further kidney damage.
It is essential that your cat's urinary flow rate be monitored so that signs of progress can be tracked. A urinary catheter may be necessary to accurately determine urine volume, but it is important to place and clean catheters properly to avoid the development of a bacterial urinary tract infection. Your veterinarian will advise you on the best way to go forward with this procedure.
Due to the fact that there are such a wide variety of causes for oliguria and anuria, there is no one specific prevention method that can be suggested. A generally healthy lifestyle may be helpful.
