urinary retention

The most common causes of urinary retention in elderly patients are bladder-neck obstruction, posterior-urethral stricture, and neurological abnormalities. The majority of cases of acute retention occur in men as a result of bladder-neck obstruction due to prostatic hypertrophy. People with a stricture of the posterior urethra can undergo a reconstruction procedure with excellent results. In temporary acute paraplegia, a catheter can be left in for up to six weeks. Antibiotics should be given continuously during this time. In people with permanent neurological damage, division of the external urethral sphincter may remove the necessity for permanent catheterization.
