History: Individuals with acute bacterial prostatitis will report chills, low back pain, suprapubic and perineal pain, the urge to urinate frequently at night (nocturia), painful urination (dysuria), and a variable, slow urine stream that can be secondary to bladder outlet obstruction. Diffuse muscle and joint pain (myalgia and arthralgia respectively) may also be reported.
Symptoms reported by individuals with chronic bacterial prostatitis are inconsistent. Although some have no symptoms (asymptomatic), most have varying degrees of the irritation and urinary bladder dysfunction common to acute bacterial prostatitis. Low back pain, perineal discomfort, myalgia and arthralgia are also common complaints.
Individuals with nonbacterial prostatitis report symptoms similar to either the acute or chronic bacterial forms of the disease.
Physical exam: Insertion of a gloved finger into the rectum to feel the prostate (rectal palpation) will reveal a tender, swollen prostate gland. The inflammation may affect all or only part of the prostate. In individuals with chronic bacterial prostatitis, the prostate may feel normal, firm, or swollen in certain places. Palpation may also reveal a grating feeling (crepitation) if large prostatic stones (calculi) are present. Examination of individuals with nonbacterial prostatitis will reveal symptoms similar to those of acute or chronic bacterial forms of the disease.
Tests: For all types of prostatitis, a complete blood count (CBC) with a white blood cell differential may be performed to identify signs of infection. Urinalysis and urine culture can be performed to identify white blood cells, red blood cells, or bacteria in the urine (pyuria, hematuria, or bacilluria, respectively). A culture of the prostatic secretion obtained after massaging the prostate gland may also be performed. X-rays can be taken to identify the presence of complicating factors, such as prostatic enlargement or stones (calculi) in the prostate. In patients with chronic bacterial infections, a flexible fiberoptic viewing scope (endoscope) can be inserted into the tube (urethra) draining urine from the bladder (urethroscopy) in order to identify the presence of complicating factors such as prostate gland enlargement, benign prostatic hypertrophy (BPH), blockage of the urethra (urethral stricture), or kidney (renal) infection.
