Can holding in your urine really cause a uti? I thought urine was sterile.

Yes. Good question: Urine is sterile, however bacteria are liable to travel up a female urethra, which is short, from within labia & area around urethral meatus (opening). Regular or frequent urination empies bladder of urine & unattached bacteria. This prevents utis in many women. However, bacteria have time to multiply & attach to bladder lining & cause UTI when subject holds urinating. Specially true after sex.

How is urine actually produced?

How is urine actually produced?

Filtered in kidneys: Through the filtering units called glomeruli. The water passes through the thin capillaries out into the filtering space in the kidneys' filtering units. The water carries with it the waste chemicals and passes through tiny tubules the collect together making bigger ones and finally exit the kidney as a large one called the ureter that ends in the bladder that stores the urine till voiding occurs.
