How is urinary incontinence (UI) in men diagnosed?
The first step in solving a urinary problem is talking with your health care provider. Your general medical history, including any major illnesses or surgeries, and details about your continence problem and when it started will help your doctor determine the cause. You should talk about how much fluid you drink a day and whether you use alcohol or caffeine. You should also talk about the medicines you take, both prescription and nonprescription, because they might be part of the problem.
You may be asked to keep a voiding diary, which is a record of fluid intake and trips to the bathroom, plus any episodes of leakage. Studying the diary will give your health care provider a better idea of your problem and help direct additional tests.
A physical exam will check for prostate enlargement or nerve damage. In a digital rectal exam, the doctor inserts a gloved finger into the rectum and feels the part of the prostate next to it. This exam gives the doctor a general idea of the size and condition of the gland. To check for nerve damage, the doctor may ask about tingling sensations or feelings of numbness and may check for changes in sensation, muscle tone, and reflexes.
EEG and EMG
Your doctor might recommend other tests, including an electroencephalogram (EEG), a test where wires are taped to the forehead to sense dysfunction in the brain. In an electromyogram (EMG), the wires are taped to the lower abdomen to measure nerve activity in muscles and muscular activity that may be related to loss of bladder control.
For an ultrasound, or sonography, a technician holds a device, called a transducer, that sends harmless sound waves into the body and catches them as they bounce back off the organs inside to create a picture on a monitor. In abdominal ultrasound, the technician slides the transducer over the surface of your abdomen for images of the bladder and kidneys. In transrectal ultrasound, the technician uses a wand inserted in the rectum for images of the prostate.
Urodynamic testing focuses on the bladder's ability to store urine and empty steadily and completely, and on your sphincter control mechanism. It can also show whether the bladder is having abnormal contractions that cause leakage. The testing involves measuring pressure in the bladder as it is filled with fluid through a small catheter. This test can help identify limited bladder capacity, bladder overactivity or underactivity, weak sphincter muscles, or urinary obstruction. If the test is performed with EMG surface pads, it can also detect abnormal nerve signals and uncontrolled bladder contractions.
