Bladder obstruction - Not urinating or urinating very little despite drinking enough fluid; producing little urine despite straining; pain due to a full bladder
Acute kidney failure - Not urinating or urinating little, with little discomfort, despite drinking enough fluid
Deep bone pain, especially in the back, hips, or thighs, or bone fracture - Possible sign of advanced prostate cancer that has spread to the bones
Spinal cord compression is a true emergency and may be the first sign of cancer. It occurs when the cancer has spread to vertebrae of the spine and tailbone region. The weakened vertebrae can collapse on the spinal cord, causing symptoms and problems with function.
Symptoms depend on the level at which the spine is compressed. Typical symptoms that might signal acute spinal cord compression include:
Increased difficulty urinating or moving your bowels
Difficulty controlling your bladder or bowels
Decreased sensation, numbness, or tingling in the groin or legs.
These symptoms are often preceded by pain in the hip (usually one sided) or back lasting a few days or weeks. Such symptoms require immediate evaluation in the nearest hospital emergency department. Failure to be treated immediately can result in permanent spinal cord damage.
