Jen, I keep my fingers crossed. However as a blockage is a very serious thing and can come again it is still worth thinking of the surgery. Tigris had no crystals and no urethral plug (that's Rutherford's thing), so he was not totally blocked.

I got great informations about the surgery from Phred. There is much info and links in Tigris' thread below.

Me too I hope Tigris can do without it but it is my fallback position if it doesn't work out with some cortisone from time to time.

All the best for you and Rutherford.
