Justin  is it valium or diazepam the generic form for it.  How much is the
dosage?

 I wonder if the vet knows that it can cause problems urinating.  I have a
cat on diazepam 2mg x2 a day for epilepsy.   Valium is a drug that has to be
careful monitored in cats it can cause liver dysfunction and kidney damage.
Full blood works are needed often specially liver enzymes test

valium side effects
More Common Side Effects:
Drowsiness, fatigue, light headedness, loss of muscle coordination.

Less Common Side Effects:
Anxiety, blurred vision, changes in salivation, changes in sex drive,
confusion, constipation, depression, difficulty urinating, dizziness, double
vision, hallucinations, headache, inability to hold urine, low blood
pressure, nausea, over stimulation, seizures, skin rash rage, sleep
disturbances, slow heartbeat, slurred speech, tremors dizziness, yellowing
of skin and eyes.

the generic form diazepam have about the same side effects

give your cat a warm enema

Two of the possible complications of a urinary tract obstruction are
urethral damage or spasms and/or damage to the bladder detrusor muscle from
overdistention.  When the bladder becomes overdistended and remains
stretched for any length of time the tight junctions between the muscle
fibers loosen up and separate a little. These little gaps between the muscle
fibers interrupt the wave of motor nerve impulses across the bladder wall
that control bladder contraction.  So, even though the obstruction has been
removed, the cat can't voluntarily contract his bladder and urinate.

One way to determine if the detrusor muscle has been damaged is by
expressing the bladder manually (don't do it yourself - ask your vet show
you how).  If he has a good urine stream when his bladder is expressed, that
means he doesn't have any outflow obstructions and his urethra is intact
and that his problem urinating is probably the result of a damaged detrusor
muscle. If the stream is weak he could still have a partial obstruction (or
recurrence) or urethral spasms.

Unless the bladder was severely overdistended for any length of time, the
tight junctions between the muscle fibers should tighten up and return to
normal and he should be able to contract his bladder and urinate on his own
again.  I don't know how long it will take before he's urinating
normally because I don't *if* or how badly the detrusor muscle has been
damaged.  *If* the detrusor muscle has been damaged, you're probably going
to have to keep his bladder empty so that the tight junctions can reform-
which means either expressing his bladder manually or using a urinary
catheter. Both carry risks: catheterization can damage the urethra and/or
cause inflammation and dysuria as well as introduce bacteria into the
urinary tract.  Expressing the bladder can also damage the bladder.  The vet
must be sure that the bladder wall is intact before applying pressure.

Yes- because valium seems to help relieve urethral spasms which are fairly
common after the removal of an urethral obstruction.  That might be all
that's necessary- I sure hope so- even though I don't like to use valium in
cats because it can crash a cat's liver.

If his urethra is intact and he doesn't have spasms or a partial
obstruction, and his urine stream is strong when his bladder is expressed,
you might want to speak to your vet bethanechol- it increases detrusor
muscle tone. I'm not crazy about bethanechol but it does work and its
immeasurably less stressful for the cat. Bethanechol seems to work much
better if therapy is begun after a few days of keeping the bladder empty- at
least that was my impression with our cats.

An antibiotic is a good idea since he was probably catheterized.  Hang on to
the appetite stimulant because if your vet prescribes bethanechol- you're
gonna need it. ;)

Best of luck,

Phil

   Kim was given a Rymadil (sp) shot for her pain and it was very
effective.
It's not good for liver long term but any drug has side effects. AFAIK
in  the
UK, they don't tend to give Valium for  FLUTD as a standard practise.
