A "Pampered" cat passes blood in the urine - FLUTD

For the past 3 months after adoption of this 1-year-old abandoned cat, the owner used "Pampers" to cover his backside when she goes to work.  

The cat could not pee and passed blood in the urine. Why?
Dr Daniel catheterised the urethra with no apparent obstruction. Thick turbid bloody urine flowed out with difficulty. The bladder was irrigated with saline and after 2 days, the owner took the cat home. 

"The paraplegic cat still passes blood in the urine but much less," the owner told me after one day at home. She emailed me an image of blood stained urine on the Pampers. "The bladder is much inflammed and bleeding," I said. "It will take a few days for the bladder mucosa to recover. No more wrapping around of the backside with Pampers and prevent the other cat licking his back area. No more dry cat food."

This is a strange case of FLUTD or FUS. Urinalysis showed lots of blood, white blood cells and bacteria. The actual cause is unknown but I hypothesize that the cat could not pee normally as his penile tip is blocked by the wrapping Pampers too tightly or that the penile tip had been injured or licked such that it became painful. So, the cat did not pee much and urinary stasis inside the bladder for some time caused bacterial infections and bleeding of the bladder.
