186 The Urinary System<br />

<strong>and</strong> functional problems, such as VESICOURETERAL<br />

REFLUX (a condition in which urine flows back into<br />

the ureters from the bladder). The procedure<br />

requires no preparation or recovery <strong>and</strong> takes<br />

about 20 minutes to complete. Some people experience<br />

discomfort during the instillation <strong>of</strong> the<br />

contrast medium because it creates the pressure <strong>of</strong><br />

a full bladder. Minor discomfort or burning may<br />

occur with URINATION for a day or two after the<br />

procedure.<br />

dysuria PAIN, discomfort, or burning with URINA-<br />

TION. Dysuria may be primarily external (occur<br />

with the passing <strong>of</strong> URINE through the URETHRA) or<br />

internal (felt as discomfort, pressure, or pain<br />

within the lower pelvis). Dysuria is most commonly<br />

a symptom <strong>of</strong> CYSTITIS (INFLAMMATION or<br />

INFECTION <strong>of</strong> the BLADDER <strong>and</strong> urethra), though it<br />

occurs as a symptom <strong>of</strong> numerous conditions<br />

involving the genitourinary tract. The diagnostic<br />

path begins with urinalysis <strong>and</strong> may include other<br />

diagnostic procedures, depending on the full spectrum<br />

<strong>of</strong> symptoms <strong>and</strong> the findings <strong>of</strong> the urinalysis.<br />

Treatment targets the identified causative<br />

condition.<br />
