Method for controlling flow of urine in a patient's urethra, ureter, renal pelvis or bladder

摘要

There is provided a method for controlling a flow of urine in the urinary passageway of a patient's urethra, ureter, renal pelvis or bladder. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the urinary tissue wall) at least one portion of the urinary tissue wall to influence the flow in the urinary passageway, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the urinary passageway. The method can be used for restricting or stopping the flow in the urinary passageway of a urinary incontinent patient, or for actively moving the urine in the urinary passageway, with a low risk of injuring the urethra, ureter, renal pelvis or bladder.
