Currently, the standard to conduct tests to determine bladder diseases are invasive tests that jam stuff up in peeholes. Thanks to the advancing medical tech, there may be a better way soon: a wireless near infrared spectroscopy device strapped right above your bladder.

Using an NIRS device and its software measured "the differences in the amount of light shone through the skin to—and returning from—the bladder wall," which let researchers look at micro-circulation in the bladder to see things like changing hemoglobin concentrations and how much oxygen is in the blood. Hence, no jamming necessary.
