abstract
Management of urinary retention after spinal cord injury in dogs is often needed and can include use of medications to relax the urethral sphincter. This was a retrospective study evaluating two such medications, prazosin and diazepam, and whether dogs treated with these medications had different lengths of hospitalization, urinary continence levels, or development of bacteriuria compared to dogs not receiving these medications after thoracolumbar hemilaminectomy for intervertebral disc herniation (IVDH). Electronic medical records were searched for dogs that underwent CT or MRI followed by a hemilaminectomy between the 3rd thoracic and 3rd lumbar vertebra for treatment of IVDH. Dogs were grouped based on whether or not they received a medication to aid in urethral sphincter relaxation (either prazosin, diazepam, or both medications). The total length of hospitalization, urinary continence at the time of discharge, and presence of bacteriuria were recorded from the medical file. Medical records from 71 dogs were included in the analysis. There were no significant associations between administration of prazosin and/or diazepam and length of hospitalization or urinary continence scores at the time of discharge from the hospital (P>0.05).
