In anatomy, the urethra (from Greek οὐρήθρα – ourḗthrā) is a tube that connects the urinary bladder to the urinary meatus for the removal of urine from the body of both females and males. In human females and other primates, the urethra connects to the urinary meatus above the vagina, whereas in marsupials, the female's urethra empties into the urogenital sinus.
Devices, methods, and systems for shrinking tissues
InactiveUS6091995AReduce power levelControl depthSurgical needlesInternal electrodesSphincterPelvic supports
Devices, systems, and method for treating urinary incontinence generally rely on energy delivered to a patient's own pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder. The energy will preferably be applied to the endopelvic fascia and / or an arcus tendineus fascia pelvis. The invention provides a variety of devices and methods for applying gentle resistive heating of these and other tissues to cause them to contract without imposing significant injury on the surrounding tissue structures. Alternatively, heat-applying probes are configured to heat tissue structures which comprise or support a patient's urethra. By applying sufficient energy over a predetermined time, the tissue can be raised to a temperature which results in contraction without significant necrosis or other tissue damage. By selectively contracting the support tissues, the bladder neck, sphincter, and other components of the urinary tract responsible for the control of urinary flow can be reconfigured or supported in a manner which reduces urinary leakage.

Incontinence sling
A sling for controlling urinary incontinence is disclosed. The sling is formed from a tube having substantially lengthwise inextensible end portions and an elastically lengthwise extensible intermediate portion between the end portions. The intermediate portion has a U-shape which cradles the urethra. The end portions extend through the abdominal tissue to anchor the intermediate portion in position. The sling places the urethra under a transverse compressive load to hold it closed and prevent inadvertent urination. The tube is formed from interlaced filamentary members. Interlacing may be by warp knitting, weaving using a leno weave or braiding using a tri-axial braid structure. The end portions have a rough texture to facilitate anchoring in the tissue of the abdominal wall. The intermediate portion is smooth and soft to prevent tissue erosion.

Urological device for the incontinent male
The present invention features a device to prevent the unwanted flow of urine in incontinent human males. This penile clamp is designed to provide an external pressure applied to the underside of the penis at the base thereof to close the urethral canal. The apparatus includes a rigid projection on the lower member of the device that applies a concentrated force on the canal. The upper bar of the device provides an attachment for a pad as an integral part of an easily disinfected clamp that is hinged at one end and provided with an adjustable tensioning closure device at its other end. The closure device is easily removable to allow one hand release of the penis restriction. A screw-type adjustment is easily set and is easily disassembled by a quick-release apparatus. While the clamp can be closed over the penis of an incontinent male to prevent urination, it does not appreciably restrict blood flow therein.
