History: Individuals with prostatic hyperplasia may report a decrease in the force and diameter (caliber) of the urine stream, difficulty starting urination (hesitancy and dribbling), the need to urinate frequently during the day or night (nocturia) with only small amounts of urine produced at each urination, disruption of the urinary stream (intermittency), a feeling of incomplete bladder emptying, increasing desire to urinate (urgency), and involuntary loss of urination (incontinence). Physical exam: An enlarged prostate can be detected using a gloved finger inserted into the rectum (digital rectal exam). The lower abdomen can be examined by pressing with hands (palpation) to determine if the bladder is distended. These procedures should be done routinely as part of an annual physical examination. Tests: Additional tests may be performed if a digital rectal exam indicates an enlarged prostate. Urinalysis and urine culture are performed to rule out infection. Blood chemistry tests including BUN and creatinine are used to measure kidney function. A prostate-specific antigen (PSA) test that rules out prostate cancer should be performed on a regular basis. A transrectal ultrasound (TRUS) uses high frequency sound waves to examine the size of the prostate. If necessary, kidney function can be assessed using radiopaque dye (pyelography). A test that measures urine flow (uroflowmetry) may be performed to give additional information about the severity of the obstruction and to rule out other defects in the urinary system. A complete urodynamic study may be required. |
