Aspects of bladder mapping are described herein. According to one aspect, an exemplary method comprises: generating, with an imaging element, a video feed depicting a bladder wall； establishing, with a processor, markers on the bladder wall in the video feed； tracking, with the processor, relative movements between the markers； and/or identifying, with the processor, a location of a contraction of the bladder wall based on the relative movements. Associated devices and systems also are described.
