Humorous story to remember this by: One doctor had an elderly gentleman who came in repeatedly saying, “I can’t urinate.”
The doctor gave him Hytrin, a medicine to help men with prostate trouble pee. He still couldn’t go. Finally, the doctor took him to the Emergency Room to put a Foley catheter in him. He starts to scream, “NO! I just can’t pee!”
The doctor remembered big urine vs. little urine and asked how many days since the gentleman pooped. It had been about 4 days. Milk of Magnesia cured him when a Foley catheter put into his bladder couldn’t.
