Urethral disease

---

Urethral disorders are not common in old cats or dogs. Clinical signs are usually dysuria and haematuria. Obstruction may be caused by uroliths, foreign bodies or neoplasms. In male cats with feline urologic syndrome (FUS or feline lower urinary tract disease) urethral scarring and stenosis may be a complication following repeated attempts at catheterisation. If obstruction is prolonged urinary incontinence may be a complication once the obstruction is removed.
