Hey Pet Parents & Pet Lovers,
It can be difficult to choose whether or not you should put your cat through the trauma of a surgery, especially when complications are serious. Last year when we had to make the decision of whether or not we would put Beau under the knife we called a number of our vet friends for second (and third… and fourth… and fifth) opinions to make sure that it was the right choice. All-in-all, we’ve had a very positive experience with Beau’s operation and he has not experienced any complications other than a couple of urinary tract infections after the surgery (induced by stress) which was easily fixed with medication.
If this is the first article you read from our site I also recommend you check out my post about Beau’s recovery after his PU Surgery as well. It covers a detailed account of the first week of recovery as well as suggestions for aftercare. However, let’s get back to the main reason you’re here.
What are the Most Common Complications Associated with a Perineal Urethrostomy?
Re-Occurring Urinary Tract Infections
It’s an odd thing to hear that your cat may experience urinary tract infections after going through such an extreme procedure, but it’s important to note that the PU Surgery isn’t meant to cure the underlying issue (ie. the development of stones and crystals.) Unfortunately, cats who undergo the PU Surgery are actually more prone to getting UTIs due to how exposed the manufactured urethra is. Although this is true, as mentioned above, Urinary Tract Infections are fairly easy to cure after the surgery and your cat will be at a much lower risk of blocking (although that is still possible.)
To put this into perspective, since Beau’s surgery in November 2017 he has gotten 2 urinary tract infections. We are uncertain what the causes of his original urinary tract infections were before the surgery (although we assume it was from food that altered the pH of his urine), but we are 99% sure that the two urinary tract infections this year (2018) were caused by stress (as he got one soon after we adopted a new kitten and the other was after we moved.) I will make sure to keep this page updated with if Beau gets any other urinary tract infections so it can help you make a decision whether or not this procedure is for you.
Urinary & Fecal Incontinence
Incontinence usually occurs in the first few weeks of recovery and does not usually occur after, however, this doesn’t mean that this is always the case. Beau experienced urinary incontinence until he had his stitches removed. This was believed to be caused by the stitches irritating the tissue of his manufactured urethra, causing him to dribble or want/need to urinate. Cats may continue to express urinary incontinence until they get used to the sensation of peeing from their new urethra as they no longer have a muscle to control the stream of their urine. The majority of cats will learn how to control their urine, however, there are a few who will continue to be incontinent for the rest of their lives.
As for Fecal Incontinence, this is a bit more complicated. It is rarer than urinary incontinence and is often a sign that the brain is not communicating with the colon properly. Although that is true, fecal incontinence is also caused by infections on the anal glands or medications. Medications being the primary reason for fecal incontinence early on in a feline’s recovery after a perineal urethrostomy.
Rectal Prolapse
Similar to humans, prolapse usually is tied to other conditions such as constipation, struggles to urinate or diahrea. If you notice your cat struggling to urinate or defecate after surgery make sure to consult with your vet as there are plenty of medications that can help relieve your cat of these problems. This will help make sure that they are healthy and safe. (We had the issue of Beau not being able to defecate for days, we were given a stool softener that helped him within an hour.)
Avoiding the Litter Box
Cats learn by making connections. I meow, you feed me. I push my head against you, you pet me. So it’s not uncommon for cats to avoid litter boxes if they have experienced a number of blockages/urinary tract infections in the past. It may be useful for you to create some litter boxes out of cardboard boxes if your cat begins ignoring the litter box. Try to break their association to pain from the litter box.
Rectourethral Fistula
This is actually something we were never warned about, but rectourethral fistula is when a hole is created between the anus and urethra causing urine to seep out of the anus or fecal matter to pass through the urethra. This hole is commonly created while in surgery, however, may occur after the surgery. Surgeries that have been known to cause fistulation include surgeries on bowels, cervix, uterus, prostate, or urethra. Oddly enough, fistula can also be caused by radiation therapy, ultrasounds (when intense), and cryotherapy.
Cats who experience Fistula will commonly get extremely sick, so it will be clear whether or not your cat is experiencing this complication. Treatments are not easy to perform and may cause further complications, however, it is possible.
Perineal Hernia
Unfortunately, it is uncertain what causes this form on hernia, but vets seem to believe that it may be caused by the diaphragm breaking or weakening. Perineal Hernias happen to a number of cats, even if they haven’t gone through any surgeries and are most commonly seen in cats aged 7-9.
Perineal Hernias may cause constipation, the inability to urinate, straining, depression, abdominal pain, lethargy, incontinence, swelling on the anus, vomiting and other forms of pains/illness. Cats are able to recover from this form of a hernia, but only through surgery and antibiotics.
Scar Tissues Resealing
When incisions are made tissue seeks other tissue to bind to in hopes of repairing itself. This can, unfortunately, occur after a perennial urethrostomy, however, is completely reversible through a simple catheterization to help reopen the hole. This is similar to the catheterization that occurs when cats need their bladder flushed from crystals or stones.
Conclusion
Although the list may feel long and fatal, I’m really grateful that we have not experienced the majority of these issues. Beau is more active than he has ever been, and while he has experienced a couple UTIs in the past year, seeing him so happy makes us happy. He has more energy than he had (even before the surgery) is much more playful and has returned to his regular cuddly self. I will say, the PU Surgery is not necessary for the majority of cats, however, if it is offered as a last resort for a cat it is definitely something to consider. So far, I haven’t heard of a fatal experience (and when I say this, I mean the folks who have contacted me for advice on the procedure and have gone forward with it. This number is currently over 50 pet parents, which makes me feel like the odds are fairly high for a smooth recovery.) I would highly recommend consulting a few vets before going through the surgery though. Give a few in the area a call to see how many PU Surgeries they’ve performed and ask them how many cats have had complications since. Our vet had a number of surgeries under his belt and only one cat had complications after (being incontinence) so we felt fairly comfortable. It also eased us to know that he had actually adopted a cat who had to undergo a PU Surgery when the cat was surrendered and the original pet parents asked to euthanize the cat. We’re very lucky to have had the vet we had, and I hope that if you have to go through this process you do too.
As always if you see anything missing on this list please let me know and if you have any questions or concerns leave them in the comments below and I will get back to you as soon as possible.
Our 4 year old cat had PU surgery in Sept 2021. We have had nothing but trouble since. š He wouldn’t be alive now though if we hadn’t gone through with the surgery. He has had scar tissue seal it up 2 o r3 times. He’s had repeated UTI’s. Three weeks ago he was totally blocked again with a mucus plug full of struvite crystals. and he had a UTI. Today I just took him in again because he can’t pee. We have spent over $10,000 on him and I can’t afford to keep taking him in. Each time it costs between $1000 and $1500 and I can’t do that. I love this cat dearly and do NOT want to have him put down, but I think that is what we’re going to have to do since we can’t get this under control. Over a year and we are still dealing with this. He’s such a sweet loving kitty and I desperately don’t want to lose him. š PU surgery does not always work unfortunately.
Hey Diana, thank you for sharing your experience and I’m extremely sorry to hear about your kitty. It’s very unfortunate that PU surgery doesn’t work for every cat, and there are always risks, so I’m sorry this was true for you. I do also understand the struggle to make the decision to let go of a little one, especially when complications keep re-occurring and wish I could offer you more than my solidarity.
My cat recently had PU surgery. About a month ago. For the last 2 weeks he has been displaying some incontinence and usually tracks urine throughout the house. So frustrating. We changed his litter back to what he was using before surgery, and it seemed to help a little bit. I notice some dribbles after he gets up from a spot as well. So challenging.
I hear you and I’m sorry to hear that you’re struggling. I’m really hoping that as your little one continues to heal he experiences much less incontinence. Please feel free to keep us updated on the progress <3
This story about Beau was helpful. Thank you. Our cat, Spartacus, had stones that didn’t dissolve after 6 weeks on urinary diet and he would pee anywhere in the house. So we had the surgery to remove the stones. Unfortunately, the catheter got stuck in his urethra during surgery and the vet called and said that he needed to do a PU or euthanize our cat! He said the cost would be double with the PU. I didn’t even know catheters could get stuck. The vet called it a very rare complication.
We are really worried that the stuck catheter may have damaged his urethra. He is now 2 weeks post-op and he does use the litter box to pee and poop. But he also has a damp bed everyday from pee. The surgeon thinks that his bladder sphincter should be functional. So hopefully this problem is from one of the possibilities that you mentioned. What an ordeal this has been!
Oh my Andy, it seems like you’ve been through quite a bit with Spartacus. I’m glad that he’s doing well 2 weeks post-op and I hope that the damp bed isn’t going to be a complication forever. I have heard of some cats soiling themselves and their beds for a few months before they gain full control over their bladder, so yes I’m hoping that’s also the case with your little guy. Please feel free to keep me updated on Spartacus and his recovery. Wishing you both the very best.
Thank you so much for your detailed blog. Our kitty had PU surgery on Monday and we had been struggling to figure out what to do over the past few days and concerned that he was not going great. I had been searching on the internet and your article popped up – what a find. YOUR story has helped us so much. My sincere thanks and appreciation for taking the time to detail your daily experiences. I can’t thank you enough.
Steven, absolutely no worries! Really glad I could help. Wishing your little guy the absolute best recover and never hesitate to comment if you have any other concerns <3
Of my six kitties, 5 have been boys, and fortunately none have had issues like that. I have known of a couple who underwent that corrective procedure, and it helped them. I guess if it would make a big difference, I would consider it. We want our furkids to feel good as best we can help them.
I am happy that is has helped Beau do so much better. And that his complications were minimal:)
Any surgery/procedures are scary, and even more so for these little furry ones of ours.
I’m surprised that 2/3 of the male cats in my life have had urinary problems. Walker though has been great with just the food change (to a urinary specific food). I guess with Beau it just wasn’t enough š
What a sweet kitty … sad that he had to go through the surgery – but we’re glad he didn’t experience all these complications!
I’m really glad too. It’s so good to have Beau in our lives still <3
I am glad your sweet boy did well with this.
I am too <3
We’re glad Beau is doing well now. Every surgery is a risk, and it’s very important to be aware of the complications. Great post ! Purrs
Absolutely! Glad you liked the post friends!
It’s good that Beau didn’t suffer from those other complications! And I know about stress-induced UTI, as I was taking Angel to an holistic vet, who wanted repeated appointments. She developed an infection after a few visits, and I took her to a ‘regular’ vet for antibiotics. We never went back to the holistic vet, because the help wasn’t worth the stress on the cat!
I’ve never visited a holistic vet yet. I feel like there’s a time and place for them. Bladder infections, to me
… Especially after my experience with Beau, would never be the time for visit one. (again, in my opinion). Urinary problems are so terrifying to me!
