Operation of urethral calculi in dogs

1 case situation

White Jingba dog, male, 2.5 years old, weight 8kg, is the main breed of a dog in Zhichun, Haidian, Beijing. According to the pet master: the dog began to show signs of dysuria, urinating frequently, only a few drops at a time. Other pet clinics have seen a doctor, punctured once, slightly relieved the symptoms, but not the second day, and the use of furosemide, still ineffective, the symptoms are more serious, see its micturition action in the morning, but no urine, mental pain. Therefore, he came to our hospital for medical treatment.

2Clinical examination

The dog's abdominal wall was sensitive and tense, refused palpation, the bladder was full, and the glans were red and slightly swollen. X-ray film showed that there were two stones about 3mm in diameter at the root of the penis, depending on each other. There were no stone-like suspicious bright spots in the bladder and posterior urethra. The initial diagnosis of urethral calculi was decided to adopt urethrotomy.

3Surgical treatment

846 mixture mixed with ketamine according to 3 ∶ 1 0.8ml intramuscular injection anesthesia, supine Baoding, routine shaving and disinfection. Aim at the X-ray film and touch the root of the penis carefully with your hand to find out the location of the stone. And lift the penis with the left hand in the presence of the stone, making the skin tense. Make a 1cm long skin incision longitudinally, and then carefully cut the cavernous body of the urethra to stop bleeding at any time to clearly distinguish the position of the knife edge, so that it can be cut across the board without damaging more tissues. Finally, the urethral mucosa was cut open and 2 yellowish stones were removed with hemostatic forceps. After checking that there is no smaller stone, push the catheter into the bladder from the orifice of the penis. Be careful when passing through the incision. Rough force will damage the urethra. From the urine derived from the filling bladder, it can be concluded that the stone has been eliminated without fine powdery sand. Rinse twice with warm saline and indwelling catheter. The urethral tissue was sutured continuously with No. 15 catgut, 0.2g ampicillin powder was spread, and the skin was sutured with nodules. Finally, the urethral catheter mouth is sutured at the glans to prevent it from being blamed or taken out by the dog itself.

In order to prevent the dog from licking the wound, put a "Elizabeth" cover on it, and stick it to the surgical incision with "Bundy" (apply iodine tincture immediately after operation). Ampicillin was injected intramuscularly twice a day, 0.5g each time for 3 days. On 0.8ml/ day, catheter was pulled out after subcutaneous injection for 5 days. The wound healed well and micturition was normal.
