This is a slightly different form of urine retention. Well, really it's just keeping it in a bottle.

Pathophysiology

Differential Diagnosis

Clinical and Associated Features

  • Neuro
    • Spinal injury - you get a spinal injury
    • MS - basically, a series of temporary neurological deficits, becoming longer and more frequent (eventually permanent). Urinary problems is one of these deficits but optic neuritis is common plus any other neurological deficit. Must be 'disseminated in time and place' i.e. different locations for the lesions, not related in time.
  • Bladder - you don't wee. Might get abdominal pain and urgency as the wee builds up.
  • Urethral blockage - oliguria, spraying/double-stream, dribbling, sometimes urinary frequency, UTI, mild dysuria
  • Prostate
  • Drugs - any of the mentioned ones might give you a bit of the ol' urinary retention.
