My wife and I thank you all for your encouragement and responses. I have been documenting our journey just in case this worked so I could hopefully help others. We still have a long way to go but there is no pain and the CS I make does not hurt her in any way and never did from day one ( unlike the silver protein the doc prescribed ) so we are hopeful for an eventual full recovery.
The reason I am upset about the being stuck at 4oz is that 4oz is only twice as much as the doc could do before cracking and bleeding would start. I think a healthy bladder will hold at least 16oz and we were wanting to be at 8oz or more by the time we go see the doc in Feb. We are excited about that visit because we are going to request a cystoscopy and we want to hear there is no evidence of lesions or hunners ulcers both of which she had and we have pictures of. That being said, my wife has even told me that she is happy if it just stays like it is.
