My father has been diagnosed with bladder shrinkage. He is not able to control his pee for more than 15 minutes and every time he is going to pee he is just releasing about 50 ml with some blood clots in it. We have done cect whole abdomen scan and the doctors diagnosed that the bladder is shrinked. I want to know that what could be the reason. How ever, he has kidney stones and a stone in the ureter. Please help.
