Some form of erectile, urinary, and bowel dysfunction is normal following initial therapy for localized prostate cancer. But it’s important to realize that not all symptoms are normal, and that some require immediate care.

What to look for Why it is dangerous
Erection lasting for more than four hours
or an increasingly cold, bluish penis following
vacuum constriction
Lack of fresh circulating oxygenated blood can
cause damage to the penile tissue
Inability to urinate or incomplete
emptying of the bladder
A backup of urine can cause infections
and bladder or kidney damage
Constipation lasting for more than four days A backup of stool can cause infections and damage to the bowel
Excessive and/or uncontrolled diarrhea Too much water loss that accompanies diarrhea can lead to
dehydration, lightheadedness, fainting, and collapse
Excessive and/or continuous rectal or
bladder bleeding
Too much blood loss can lead to lightheadedness, fainting,
and collapse or other serious problems; blood clots in the
bladder can block the passage of urine
