Can anyone tell me if renal disease is seen a lot in guinea pigs and what kind of therapy they have used to manage it?

It's not uncommon; renal insufficiency (progressing to full renal failure) is often associated with urolithiasis, but can have other causes as well.

General signs can include loss of appetite, weight loss, lethargy, increased (or decreased) water intake, dehydration and gastrointestinal problems. Urinalysis and blood work (to evaluate BUN and creatinine levels) are useful in evaluating kidney function; x-rays can determine kidney size and check for the presence of calculi in the kidneys, ureters or bladder.

Fluid therapy can be very beneficial in improving/prolonging quality of life. Secondary gastrointestinal issues may respond to the use of Reglan, but it's not always well-tolerated. Extreme care also has to be taken with the use of NSAIDs in kidney-compromised guinea pigs; therefore, pain management can be sometimes be tricky.

Do you have a guinea pig with renal disease?

My Kona has renal disease, which the vet is still in the process of diagnosing/treating. She had blood work done yesterday, which showed that her potassium is low. Thursday she will have an ultrasound to hopefully find out what is causing the problem. Thus far, the vet has prescribed Renal K. (Anyone have any experience with it?)

If I can muster up the energy, I may start a thread on her once I have the ultasound results.

(Sef: If you happen to read this, I will be getting Creole's record this week if you are still interested in knowing how the vet went about removing the stone from his ureter.)

Yes, I'm definitely still interested in learning more about the procedure, ElvisTCB. Thanks for asking.

I'm really sorry about Kona. I've never really heard of using a potassium supplement with rabbits or guinea pigs. How is it dosed? In looking at the drug info for Renal K, it does mention renal failure among the contraindications, so I imagine it would need to be used very judiciously in her case-?

ElvisTCB, I'd like to know about that stone in the ureter procedure also. I'm still having a hard time imagining it being flushed back to the kidney.

I'm not even remotely as educated as you guys on guinea pig anatomy/procedures, so not sure what I've been saying to cause the confusion...but the vet moved the stone from the ureter into the bladder for removal (& I believe Sef wants to know how?). Either way, I will soon have his record to hopefully clear up any confusion.

Sef, all I know thus far on the Renal K is that she will be getting .03 every other day.

Sef, bpatters, here is the procedure. Hope no one minds me posting it here. I also hope you can decipher what is written, as I have no clue.

(PS: Kona had an ultrasound, & it looks like her kidneys are fine. She has an inflamed/thickened bladder wall embedded with stones that the vet wants to biopsy.)

Jeeps. I can't make out anything! Oh, a few words maybe but not enough.

This what I've been able to figure out (or think I've figured out) so far:

Caudoventral incision made midline at area of urinary bladder, extending to umbilicus. Abdominal viscus visualized; dilated right ureter; stone isolated at neck of bladder in ureter, several small stones found in distal right calpers [cowpers?] gland. Area[?] packed of w___ _____ gauze, of incision made into bladder near neck, stone gently manipulated forward into bladder for removal. 4-0 PDS _____ and SI to close. Area flushed well. Calpers gland tip with stones _________ and removed. End over sown 4-0 PDS. Pack and ____ changed. .9% NACI flush again. 3-0 PDS to close….

I can't really tell what she's saying about the packing material, though, or how she removed the stones in what she refers to as the 'calpers' gland (there is something called a Cowpers gland, but I can't find the other spelling).

From what I gather, the ureteral stone removal wasn't a backflush through the kidney (which is what I was originally thinking); she went in through the bladder and manually manipulated the stone out of the ureter and into the bladder for removal. It looks like maybe the stone was right at the opening of the bladder, and doesn't seem to have adhered to the ureter wall.

Interesting stuff!

Thanks, ElvisTCB, for posting it! :)

I've got a few words. I think what Sef translated as "viscus" is actually "viscera." The Cowper's gland tip was ligated and removed. The Cowper's glands are small glands at the base of the penis near the urethra.

Like Sef, I see no backflushing of anything. Looks like a straight surgical removal to me, except that the stone was right at the end of the ureter as it attaches to the bladder, and was manipulated out of the ureter and into the bladder.

bpatters, you rock! Viscera and ligated. Yes!!!

I can't make out what it says at the very end, can you? I have enhanced it a little:

I had been in touch with Dr. Horton myself a while back, to ask about the procedure. She was very nice and wanted to know what questions I had, but I didn't have a chance to write back. I sent this over to her this morning and asked if she would mind "filling in the blanks," but haven't heard back yet. I think you're spot-on on those two words, BP.

Again, thanks for sharing this, ElvisTCB. Very greatly appreciated. :)

Here's another go at it:


Caudoventral incision made midline at area of urinary bladder extending to umbilicus. Abdominal viscera visualized. Dilated right ureter, stone isolated at neck of bladder in ureter. Several small stones found in distal right Cowpers gland. Area packed of with ?? gauze. Incision made into bladder near neck, stone gently manipulated forward into bladder for removal. 4-0 PDS _____ and SI to close. Area flushed well. Cowpers gland tip with stone ligated and removed. End over sewn PDS 4-0 PDS. Pack and gloves changed. .9% NaCl flush again. 3-0 PDS to close. SI body ____ SQ. SC _____

I think SI means "stab incision," and NACI is NaCl, or salt. SQ is probably sub-Q.

I can't read what is after SC, and I think we're missing the bottom of the document.

Yes, thanks, ElvisTCB.

You're very welcome! It was entertaining reading your posts trying to decipher everything.

That is the way the bottom of my document looks as well. If anything is cut off, I don't think it can be more than one line.

While Dr. Horton advised to do the surgery, she did say that she wasn't certain she'd be able to remove the stone. It sounds like perhaps the stone was in an easier location than she initially thought?

Sef, Dr. Horton doesn't work Wednesdays, so that could be why you have yet to receive a response (although I don't know how quickly you heard back from her the first time). I hope she realizes I'm just sharing info with fellow piggy owners, as opposed to questioning her. She knows I switched to her due to no longer trusting my former vet (who I had hoped to sue at the time).

I recently also requested the files of both my girls/postponed Kona's biopsy in hopes of gaining a better understanding of what is going on first & don't want her thinking otherwise.

ElvisTCB -- No worries. :) I had explained that we belong to the same guinea pig owners' group, that you had mentioned about the surgery and I was interested to know how the hydropulsion was performed, as I had lost a guinea pig (Zachary) to ureteral stones and thought that the procedure was fairly uncommon in guinea pigs. She was very friendly and offered to answer any of my questions (interestingly, she didn't say that it wasn't a ureteral hyropulsion; maybe we're missing something?).

Many thanks again! :)))
