Direct measurement of blood flow in the human bladder.
OBJECTIVE
We evaluated blood flow in the human bladder.


METHODS
In 8 surgical cases a laser Doppler flow probe was placed in the bladder dome and anterior wall. In 10 endoscopic cases the flow probe was placed in the bladder trigone and lateral wall.


RESULTS
Bladder filling resulted in reduced mean blood flow in the dome and anterior wall. After prostatectomy blood flow decreased in the dome but not the anterior wall. During endoscopy bladder filling resulted in diminished blood flow.


CONCLUSIONS
Laser Doppler flowmetry can measure blood flow changes in the human bladder.
