Dr. O,I am reading the messages on loss of bladder control. My 13 year old gelding had some bladder stones (blood on his legs were the first
indicator) and our vet. made an opening in the rectal area back under his tail and he urinated out the back this was in 2003. He healed up
fine.

He would dribble on and off and now it is pretty regular. I really notice it when I bring him in the barn to saddle him and while he is standing there he just dribbles DrOps of urine.

Any information would be appreciated. How can I tell if his bladder is full or partially full? Does this need to be done with an ultrasound?

Hello Linda,
Yes an ultrasound will determine the fullness of the bladder.

A thorough physical exam with a complete chemistry panel, CBD, urinalysis including culture, and ultrasound of the bladder to better characterize the problem would be a good start. Secondary incontinence can be from many problems. Primary incontinence can be caused by infection but also can be neurological and comes in two forms: the sphincter is either too loose or too tight and they are treated differently. Once a diagnosis is made treatment and prognosis can be considered.

In the case of undiagnosed incontinence some treatments that have found to be useful are:
1) phenoxybenzamine (0.7 mg / kg orally 4 times daily)
2) Bethanechol chloride ( 0.2 to 0.4 mg / kg orally 3 to 4 times daily)
3) There has also been a case of estrogen responsive incontinence which was treated with 2 mg ECP every other day. ECP has become difficult to get lately.
4) Intermittent week long treatments of TMPSMZ, which concentrate highly in the urine should be contemplated unless culture results indicate resistance.

Dr.O

We have taken the first steps regarding my gelding and his urine dripping. I took an specimen into my vet and the lab culture came back with these two positive tests:

Staphylococcus Xylosus
Acinetobacter Iwoffii

We had him on 35cc Procain-G penicillin for 7 days and I just took another urine sample in today. He still has some leakage but not as much.

I will see what the test results are from today 11/29/11 in a day or so. Right now my vet is suggesting urine tests every 3 months but I would like to get down to the bottom of this. I will have to go to a different vet if I need to have the ultrasound done as he no longer has the equipment to work on large animals for anything major.

Are these two positive cultures common in horses?
Thanks, Linda

Staph species are common but Acinetobacter Is not often listed in urine culture surveys of healthy equine individuals. Neither of these organisms are considered very pathogenic and are likely to be contaminants or possibly colonizing but not infecting the urinary tract however proper interpretation of these findings depends on the concentration of the organisms and whether there are clear signs of inflammation of the urinary tract, for more on this see Urination, Urine, and Urinalysis of Horses.
