Bladder and urination problems are common in people who have multiple sclerosis (MS). When a new problem develops, tests may be done to make sure that a condition other than MS is not causing the problem and to decide on the best treatment.
The following are tests commonly used to evaluate problems with the urinary tract:
- Urinalysis or urine culture
- Measurement of urine retained after normal urination (post-void residual)
- X-ray of entire urinary system (intravenous pyelogram, or IVP)
- Tests of bladder function and storage capacity (cystometrogram)
Some of these tests involve the insertion of a thin flexible tube (catheter) into the urethra; injection of a contrast medium, which shows up on X-rays; or injection of material that has low-level radioactivity.
