Surgical Removal of Bladder Stones in Canines: A Comprehensive Guide
Bladder stones, also known as uroliths, can be a painful and serious condition for dogs and cats. When these stones do not pass on their own, surgery is often necessary to remove them. This article provides a detailed overview of the surgical procedure, including the steps involved in the operation and what to expect afterward.
Understanding Bladder Stones in Canines
Bladder stones are formed when minerals in the urine crystallize and then aggregate to form stones. These stones can cause irritation, pain, and even lead to urinary tract infections if they get stuck in the urinary tract. If bladder stones are not removed, they can cause severe complications, including obstruction of the urethra and severe pain for the pet.
The Surgical Process
When a vet determines that surgery is necessary to remove bladder stones, the procedure typically involves several steps. Here is a detailed breakdown of the process used in canines:
Preparation and Anesthesia
Before the surgery can begin, the dog will be fully anesthetized. This ensures that the pet is completely uninformed of the procedure and prevents pain during the process. The preparation phase involves cleaning the surgical site to minimize the risk of infection and ensuring that the dog is stable enough for the surgery.
Abdominal Incision
The first step is to make an incision in the abdomen. This incision is caudal to the bladder. The bladder is then reflected downwards, and it is secured with temporary stays. This makes it easier for the vet to access and operate on the bladder.
Bladder Wall Incision and Stone Removal
An incision is made in the dorsal wall of the bladder to allow access to the stones. The vet will use surgical instruments to carefully remove the stones. The stones are then analyzed to determine their composition and to identify any underlying causes that might predispose the dog to the formation of more stones in the future.
Catheter Placement and Urethra Flush
In male dogs, a catheter is often placed in the urethra to ensure that any remaining stones do not block the urinary tract. The catheter is used to flush the urethra, preventing any stones from causing further blockages or irritation.
Bladder Closure and Wound Dressing
Once the stones are removed and any necessary flushing of the urethra is complete, the bladder is carefully sutured closed. To ensure a secure and long-lasting closure, a double layer closure of the bladder with absorbable sutures is used. An omental patch is also applied to the bladder to provide additional support and reduce the risk of leakage.
The abdomen, subcutaneous tissues, and skin layers are then closed using absorbable sutures. This helps minimize the risk of infection and promotes a smooth recovery for the dog.
Post-Operative Care
After the surgery, the dog will be monitored closely for any signs of infection or complications. Pain management will be a key component of the post-operative care, as the surgery can be quite painful for the animal.
Prescription diets are often recommended to help reduce the risk of bladder stones re-forming. Dietary changes can help manage the underlying condition and prevent future stones from forming. Additionally, regular veterinary check-ups will be necessary to monitor the dog's recovery and to catch any potential issues early.
Conclusion
The surgical removal of bladder stones is a relatively straightforward procedure that can effectively alleviate the pain and discomfort associated with these stones in dogs and cats. While the initial procedure itself takes only a few minutes, the preparation and recovery take longer. Proper care and adherence to the vet's recommendations can ensure a smooth recovery and reduce the risk of future complications.
