Urodynamic Events: Capillaries

The peristaltic contractions of the pelvic wall also profoundly affect the papillary blood flow. The papilla inside the pelvic wall becomes pale. As the wall contracts around it. With close observation under the microscope, it can be seen that the blood flow periodically stops and then briefly moves retrograde in descending capillaries.  In a close-up of the capillary, it can be seen how the capillary narrows with each contraction. Measurements have shown that blood flow is stopped about 30% of the time. Light and electron micrographs have shown that <xx garbled xx>.
