Urinary retention
In medicine, urinary retention is "inability to empty the urinary bladder with voiding (urination).[1] Ten percent of males over the age of 50 may have undiagnosed urinary retention during routine physical examination.[2]
In males, antimuscarinic cholinergic antagonists may contribute to retention.[3]
Diagnosis
Urinary retention may be asymptomatic.[2]
Physical examination
Physical examination may detect less than half of cases of postoperative bladder size greater than 400 ml compared to ultrasonography.[4]
Ultrasonography
Bladder ultrasonography may detect urinary retention and reduce unnecessary urinary catheterization[5], but false positives may occur due to cysts of nearby organs.[6]
Treatment
Postoperative urinary retention (> 500 ml of urine estimated by bladder scanning) may be better treated with intermittent urinary catheterization rather than indwelling urinary catheterization.[7]
The use of bladder ultrasonography may reduce the frequency of intermittent urinary catheterization among patients with spinal cord disorders.[8] Although the use of protocols with bladder scanners to reduce the frequency of urinary catheretization are recommended[9], implementing a critical pathway with a bladder scanner may[4] or may not[10] increase the use of scanning prior to insertion of a urinary catheter.
