Bladder Not Functioning At All After Kidney Stone Removal

My husband had a kidney stone removed November 2015. It was extremely large and dense. The surgeon was only able to blast 1/2 of stone, and a second procedure was scheduled. In the interim, his bladder stopped working. We are not sure if it was a pre-existing condition due to his Type 2 Diabetes. He is 6'1 and currently weighing 165. He is not a heavy man, and his Diabetes diagnose was only discovered from a Life Insurance test. He has had it for 15 years. After an stone attack in July, he knew it was time to finally attend to this stone. His urologist had been telling him for a very long time that he had an enlarged prostate and was also retaining urine after he emptied his bladder. As I said, he was told these issues, but life was "too busy" for him to take care of it. 

Subsequently after the attack, he sought a second opinion. This new surgeon (very prestigious surgeon) told me husband his prostate was not enlarged. "Music to his ears!" after years of being told it was, even though he had all the symptoms of enlarged prostate. You tell a man that, there's no looking back. He also did an ultrasound at initial consultation, and he said his bladder was empty. That was it!! Surgery was scheduled. I'm not even sure if they read his records that were sent over from his previous urologist. Seventy-seven days later, my husband has been catheterized. The second 1/2 of stone was removed, the stent removed, and he spent two days in hospital recovering after second surgery and experiencing extreme pain with bladder spasms. He has had the bladder test, and nothing. We have removed catheter weekly, wait, and then the pain is so severe, he needs to be catheterized immediately. Last time his bladder had 1400cc from 9:00am to 1:00pm. I had to rush him down to Dr.'s office. My husband is 57. He's a young guy still, and I am afraid he will never get full function of his bladder. He will begin self-catheterization next week, and we will be looking into another specialist in the city. He has suffered from spasms, UTI's, weight loss, and I feel helpless.
