In this episode, host Alyssa Watson, DVM, welcomes back Elizabeth Thomovsky, DVM, MS, DACVECC, to discuss her recent Clinician’s Brief article, “Stabilization of Cats With Urethral Obstruction Prior to Referral.” Dr. Thomovsky highlights the importance of recognizing early signs of obstruction, performing prompt physical examinations, and managing associated electrolyte imbalances, including the emergency treatment of hyperkalemia. She also outlines effective analgesia protocols and emphasizes the value of tailored treatment plans and recurrence monitoring, sharing practical tips for general practitioners on the front lines of care.

Key Takeaways
Early recognition of clinical signs, such as straining to urinate and vocalizing, is crucial for timely intervention, as electrolyte imbalances, including hyperkalemia, can develop within hours in completely obstructed cats.
Severe hyperkalemia may be indicated by bradycardia accompanied by hypothermia or characteristic changes on the ECG.
Hyperkalemia management options include calcium gluconate for rapid, cardio-protective effects, as well as insulin with dextrose, though careful monitoring is necessary to avoid hypoglycemia with the latter.
Opioids are the preferred analgesics for managing pain in obstructed cats.
Decompressive cystocentesis can provide temporary relief and time for referral when catheter placement is unsuccessful.
Recurrence rates for urethral obstruction vary significantly, and financial considerations often influence treatment options. Surgical intervention is typically warranted after three obstruction events.
