Hi, Maybe, Well, no, Definitely "hi".
That pattern is not a good one and carries some danger, so you have to let your doc know about it.
If you are slow to begin pee'ing, it's called Hesitancy. Usually the sphincter isn't relaxing when the bladder muscle is contracting.
When the stream starts and stops it's called Interrupted Stream (or "Starting and Stopping) and again it can be from a lack of coordination between the sphincter which is supposed to relax when the bladder contracts.
And if all of the urine is not emptied from the bladder it is called Urinary Retention. This can also be from the sphincter contracting too early and shutting off the flow or from inadequate contractions of the bladder muscle.
Many people with MS have this problem of poor coordination between the bladder muscle (detrusor) and the external urinary sphincter - called Detrusor Sphincter Dyssynergia.
It can be dangerous because urine that is kept in the bladder has a high tendency to become infected. Infections not only endanger our health, but urine infections are the #1 hidden cause of relapses in MS.
Finally, if enough urine is retained it can be forced up to the kidneys - especially in men - and cause kidney permanent damage, eventually kidney failure. This is not good.
Some meds can cause hesitancy, interrupted stream, and retention like some asthma meds, antihistamines, narcotics and others.
In MS the cause is almost always a spinal cord lesion, usually a thoracic lesion.
This is a Must-Know for your doctor and needs a full Urologic eval ASAP.
There is a Health Page on the Neurology of Incontinence (and would be the same neurology for your problems) that you might want to read.
Hope this helps.
