Cystocele (when the bladder falls into the vagina)
Posterior urethral valves (birth defect in males)
This condition is most common in aging men. It is often caused by BPH. Bladder stones and bladder cancer are also more commonly seen in men than women. As a man ages, his chance of developing these diseases increases greatly.
The symptoms of bladder outlet obstruction may vary, but can include:
Urine stream that starts and stops (urinary intermittency)
Waking up at night to urinate (nocturia)
Nausea, fatigue, and fluid retention if kidney failure occurs
Exams and Tests
Your health care provider will ask about your symptoms and medical history and will do a physical exam.
One or more of the following problems may be found:
Enlarged prostate (men)
Tests may include:
Blood chemistries to look for signs of kidney damage
Cystoscopy and retrograde urethrogram (x-ray) to look for narrowing of the urethra
Tests to determine how fast urine flows out of the body (uroflowmetry)
Tests to see how much the urine flow is blocked and how well the bladder contracts (urodynamic testing)
Ultrasound to locate the blockage of urine and find out how well the bladder empties
Urinalysis to look for blood or signs of infection in the urine
Urine culture to check for an infection
Treatment of bladder outlet obstruction depends on the cause of the problem. For most cases, a tube called a catheter is inserted through the urethra into the bladder. The catheter will relieve the blockage.
Sometimes a suprapubic catheter (a tube placed through the belly area into the bladder) is needed to drain the bladder.
Surgery is most often needed for long-term treatment of bladder outlet obstruction. However, many of the diseases that cause this problem can be treated with medicines. Talk to your health care provider about possible treatments.
Most causes of bladder outlet obstruction can be successfully treated if diagnosed early. However, permanent damage to the bladder or kidneys can result if the diagnosis is delayed.
When to Contact a Medical Professional
