Spartacus bladder stone surgery

Spartacus was diagnosed with bladder stones in early 2016, we have been trying to manage it since. The veterinarians were able to put in a catheter and was given antibiotics for a couple weeks.
On 9-15-2016 we noticed Spartacus trying to urinate and only a few drops were coming out, but the more he tried blood started to come out.
We took him to the emergency vet in Pasadena , they did x-rays and confirmed the stones are blocking his urethra . They tried to put a catheter in but were unsuccessful this time. The only thing we can do right now is have him wear a belly band for his incontinence as he cannot control the dribbling the stones are causing.
He will need to have surgery to remove the stones very soon or even emergency surgery if he can no longer urinate on his own.
Our family has been able to save a little over  $1000 since his diagnosis. Thank you for your support each donation is greatly appreciated.
