Urgent and Emergent Management of Acute Urinary Retention
Acute urinary retention (AUR) is the sudden inability to volitionally empty the bladder by urinating (micturition). It is often unexpected and typically painful. A physiological definition of AUR is the inability of the detrusor muscle to produce an intravesical pressure that overcomes urethral closure pressure and to sustain it to empty the bladder. In some cases of AUR, the patient is able to micturate small amounts of urine, but retains large volumes of bladder residual urine. Sustained, untreated urinary retention may lead to urinary infections, hydronephrosis, and acute renal insufficiency or failure.
