A pair of retaining devices are connected to each of the distal and proximal ends of the intraurethral bladder control apparatus. The retainer at the distal end of the apparatus preferably comprises a leaf spring having a plurality of leaves, in the preferred embodiment described herein the plurality comprising four leaves, with a safety device connected to the tip of each leaf to inhibit piercing of the bladder wall when the leaves of the distal end retainer automatically open within the bladder of the patient after placement of the intraurethral bladder control apparatus. The proximal or lower retainer connects to the proximal end of the bladder control apparatus after it is placed in the urethra of the patient, and a portion of the lower retainer abuts the labia.
