Abstract
A urethral stent is disclosed for the nonsurgical management of bladder outlet obstruction caused by an enlarged prostate. The stent is sufficiently rigid to provide support to assure patency of an intact but contracted urethral lumen but is sufficiently flexible to accommodate the natural anatomical bend of the prostatic urethra. The stent further includes means for frictionally engaging the urethral walls to anchor the device within the protstatic urethra and to prevent migration back into the bladder or down the urethra. When the need arises, the stent is easily and nonsurgically removed from the prostatic urethra.
