Causes Of Acute Nephritis

Urinary Exams Using A Cystoscope

An individual who has frequent exams of their urinary tract through a cystoscope may develop acute nephritis as a complication of their procedure. A cystoscopy is a diagnostic procedure used to view and examine a patient's urethra, ureter openings, and bladder. A cystoscope is a long, hollow, thin instrument that is maneuvered through the patient's urethra, into their bladder, and through their ureters. A special type of cystoscopy involves the injection of a contrast media or dye into the ureters so the structures and organs in the urinary tract will be represented better on an x-ray. Some individuals who have this type of cystoscopy may have an abnormal reaction to the presence of a cystoscope and or the contrast media injected into their urinary tract. In these rare cases, the immune system responds in an extreme and abnormal fashion, producing swelling and inflammation in the ureters and kidney tissues. This procedure-precipitated inflammation is a form of acute nephritis.
