I have been seeing and hearing the terms“Urethral“ and “ureteral” used interchangeably. “Urethral” does not mean “ureteral”. The first refers to the urethra, which carries urine from the bladder to
outside the body. “Ureteral” refers to the ureters, the ducts that carry urine from the kidneys to the urinary bladder.
I wouldn’t attempt to reach the ureters or the kidneys. Much danger in poking around those areas.
