Disclosed is a bladder drainage apparatus comprising a tube including a hollow interior extending through the tube a flexible anchor which behaves spring like connected to or at one end of the tube and a magnetic member connected to or at the other end of the tube. The tube is movable when the magnetic member is engaged by an external magnetic force creating magnetic traction and moving the tube e.g. outward (from its original position where the sphincter is typically closed) such that it holds open a sphincter allovving urine to brain from the bladder to the urethra to outside of the body. When the external magnetic force is released the magnetic engagement is terminated and the force of the flexible anchor pulls the tube back to its original position whereby the sphincter is again closed and accordingly urine flow is stopped or otherwise limited.
