2305. A cat and dog has difficulty peeing - follow up perineal urethrostomy in the cat

Thursday, Sep 24, 2015. Public holiday

I review the two in-patients

1. A 3-year-old male cat has dysuria after removal of the bladder and urethral stones around 2 weeks ago.
"He had never been able to urinate normally after the surgery," the owner said. Dr Daniel had prescribed the medication but the cat keeps going to the litter tray. The cat had been housed separately from the other 2 cats and had eaten his own Prescription C/D diet.

The cat came in 2 days ago. I palpated his bladder. It was swollen moderately, around the size of half an orange. Yesterday, Dr Daniel performed perineal urethrostomy and the cat now pees normally.

Urethral stricture was the cause of dysuria after bladder stone removal. The cat did not pee normally. The stone had lodged at the perineal urethra earlier and had caused obstruction. It was flush back into the bladder and removed with the bladder stones, but the cat had problems peeing post-op. So the solution was to do perineal urethrostomy and now the cat is OK.  

2. The 13-year-old Chihuahua had scrotal ablation and neuter yesterday.  He was seen by Vet 1 who had x-rayed which showed bladder and urethral stones. The urethral stones were packed tight behind the os penis (see x ray) and so the urine flow was obstructed. The bladder swelled to a mango size. The prostate also enlarged like a fish ball (see x ray). Too old for anaesthesia. Vet 1 inserted a syringe and sucked out 15 ml of the urine. But the dog still could not pee but dribbled urine.

Today, I checked on him. His urine was clear as seen at the catheter. No full bladder. His scrotum was cut away as they were swollen. The wounds are healing well.The dog goes home on Sep 27, 2015. Another dialysis SC before going home.

No problem peeing now. Cause of dysuria in the cat was urethral stricture. In the dog, it was urethral obstruction behind the os penis. X-rays
