cystitis
(sis-TY-tis)
Inflammation of the lining of the bladder. Symptoms include pain and a burning feeling while urinating, blood in the urine, dark or cloudy urine, feeling a need to urinate often or right away, being unable to control the flow of urine, and pain in the pelvis or lower back. Cystitis is most often caused by an infection, but it may also be caused by taking certain medicines (such as anticancer drugs), radiation therapy to the pelvis, being exposed to chemicals (such as perfumes or dyes), or having a catheter in the bladder for a long time. It may also be caused by other conditions, such as diabetes, kidney stones, an enlarged prostate, or a spinal cord injury.
