It’s very common to have urinary problems if you suffer from MS. Symptoms can include urgency, frequency, hesitancy, incontinence, etc.

The best way to treat this problem is getting a diagnosis. Residual urine determination is obtained either by ultrasounds or catheterization. No matter the case, very helpful are stimulants like urecholine.

Anticholinergic medications like oxybutynin, toterodine or propantheline help a slow to hyperactive bladder. However, especially during summers, care must be taken with these medications since they might decrease the sweating and lead to hyperthermia and weakness.

Another common symptom in MS is dyssynergia of the bladder and bladder sphincter.  The best aids for this condition are alpha-blocking agents like terazosin, and phenoxybenzamine. 

Nocturia, the need to get up during the night in order to urinate, is also common in MS. Of course, all the ups and downs can lead to an unsatisfactory sleep which in turn leads to fatigue next day. DDAVP (desmopression, antidiuretic hormone) can slow down urine production, thus allowing a more restful sleep.
