My mom is good about going to the bathroom during the day and rarely wets her pull up. She goes to bed with a diaper and a pull up on over the diaper and the diaper is loaded to the max in urine as well as the pull up in the mornings. And the odor is awful. Does she need to see a urologist? Is there something that can be surgically done to help her? She is 81 and she had a stroke in November of 2009. Is this normal? we have even limited her liquids at night, nothing seems to change the amount of urine in the diaper. It must be so uncomfortable to sleep in all night. Any advice is appreciated.
