Approach to urethral obstruction in cats. Part 1: presentation and stabilisation

Background: Urethral obstruction is one of the most commonly encountered emergencies in feline medicine, with a wide range of clinical signs, from dysuria to peri‐arrest. Such patients are some of the most challenging cases in feline medicine with several factors to consider; however, they can be equally rewarding. Aim of the article: This is the first article in a three‐part series. The aim of this article is to summarise a stepwise approach from presentation through to diagnosis of urethral obstruction. The second article will focus on urethral catheterisation, and immediate postcatheterisation management, while the third will focus on home management to prevent recurrent obstruction, and on addressing underlying feline idiopathic cystitis.
