Urinary Bladder Surgery for Stones in Pets | Cystotomy

Bladder stones in pets — dogs and cats mainly — are more than just uncomfortable; neglecting to treat them can be a death knell. Bladder stones, also known as uroliths, are rock-like accumulations of minerals that develop in the urinary bladder when they clump together and crystallize. These can irritate the bladder lining, be painful, cause infections, and in rare cases obstruct urine flow entirely — a veterinary emergency. For many pets that have bladder stones that do not respond to diet or medical therapy, the initial attempt at surgical removal of a cystotomy is unsuccessful, and your surgeon may need to use the laser. In this blog post, we are going to dissect what you need to know about bladder stone surgery in pets and cover the bases of ‘what are stones, why does my pet need surgery, how surgery is performed, recovery details, prevention tips, and then cover off some real-life stats as well as expert commentary. So whether you’re a new or experienced pet owner, this guide will explain everything in simple words. Table of Contents

What Are Bladder Stones (Uroliths)?

Bladder stones are hard masses of minerals that form in the bladder when urine becomes concentrated and materials crystallize. These stones can be no larger than grains of sand or bigger, and they can fill the bladder. If they move into the urethra (the tube through which urine is drained), they can obstruct the flow, a life-threatening emergency if left untreated.
