The invention claimed is: 1. A set of parts for providing a urine drainage system configured to form a fluid passageway through an external skin surface and into a bladder to permit drainage of the bladder, the system comprising: a lumen element having a proximal end portion and a distal end portion with an elongated depending lumen disposed between the distal end portion and the proximal end portion so as to form a drainage lumen, a retention element coupled with the distal end portion and configured for adjustment between a first position selected for insertion and a second position selected for retention, a lumen housing forming the proximal end portion and having a distal face configured to abut the external tissue surface adjacent to the tissue through which the depending lumen is passed and a proximal face through which a terminus of the depending lumen is formed, the lumen housing further including a first connection member, wherein the lumen element and lumen housing are formed from a single, unitary continuous component that presents an unimpeded passage from an opening in the proximal face through the lumen element; a valve housing having a first opening forming a port and catheter connector, a second opening, a fluid passageway disposed between the first opening and the second opening, a valve member disposed within the fluid passageway and configured to selectively occlude fluid flow through the fluid passageway, and a second connection member configured to selectively engage the first connection member such that a seal is formed between the valve housing and the lumen element and the second opening of the valve housing is operatively placed in fluid communication with the depending lumen when the valve housing abuts the proximal face of the lumen housing and wherein both the first opening and the valve member are disposed proximal to the proximal face of the lumen housing; a urinary catheter having a free end configured for insertion into the port and catheter connector in the valve housing to actuate the valve member to open the fluid passageway and to permit fluid flow from the distal end portion of the lumen element, through the drainage lumen, into the second opening of the valve housing, then into the free end of the urinary catheter and out through the urinary catheter. 2. The set of parts according to claim 1, wherein the lumen element is configured as an implant. 3. The set of parts according to claim 1, wherein the valve member is a ball valve having a valve ball. 4. The set of parts according to claim 3, wherein the ball valve is biased by a spring. 5. The set of parts according to claim 3, wherein the valve member has a housing including a spherical valve seat. 6. The set of parts according to claim 3, wherein the valve member has a housing including a frusto-conical valve seat for the valve ball. 7. The set of parts according to claim 4, wherein the valve member has a housing including a frusto-conical valve seat for the valve ball. 8. The set of parts according to claim 1, wherein the catheter further comprises an O-ring seal against the valve member. 9. The set of parts according to claim 1, wherein said releasable connection members are configured to engage one another with a snap fit. 10. The set of parts according to claim 1, wherein said retention element having an insertion position in which, during entry of the lumen element into the bladder from the patient's skin through a lumen-sized hole, the retention element also passes through the patient's skin and into the bladder through said same lumen-sized hole, said retention element once inserted being expandable into a deployed position having a diameter greater than said lumen-sized hole to retain the lumen element in the bladder. 11. A kit with a set of parts for providing a urine drainage system, comprising: a lumen element including a housing forming a proximal end of the lumen element and a lumen for drainage of urine, said lumen element being configured to be mounted for entry into the body of a patient from the patient's skin and the housing abuts the patient's skin to retain the position of the lumen element, said lumen element housing having a first connection member spaced from an inner surface of said lumen, wherein the lumen element and lumen housing are formed from a single, unitary continuous component that presents an unimpeded passage from an opening in the proximal face through the lumen element; a valve housing having a fluid passage that is selectively coupleable with the lumen and includes a valve member disposed within the fluid passageway, said valve member being movable to open and close said fluid passageway, said valve housing having a second connection member configured to cooperatively engage with said first connection member on said lumen element housing; a urinary catheter having a free end that is received in the valve member housing, said catheter when inserted therein pushing against the valve member to open said fluid passageway but wherein the valve member precludes insertion of the catheter distal to the proximal end of the lumen element; said lumen element housing and said valve member housing being releasably connected to one another by said first and second connection members which can be engaged with and disengaged from one another by hand to releasably connect and disconnect said lumen element and said valve member, said lumen communicating with said fluid passage when said housings are connected such that an assembled medical device is provided which is configured to drain the patient's bladder by having urine flow through the lumen, into the valve, then into the free end of said catheter, and then out through the catheter. 12. The kit according to claim 11, wherein the lumen element is configured as an implant. 13. The kit according to claim 11, further comprising a retaining element adapted to retain the lumen element in the bladder. 14. The kit according to claim 11, wherein the valve member is a ball valve having a valve ball. 15. The kit according to claim 14, wherein the ball valve is biased by a spring which is compressed by the free end of the catheter when the catheter is inserted in the valve member housing. 16. The kit according to claim 14, wherein the valve member has a housing including a spherical valve seat. 17. The kit according to claim 14, wherein the valve member has a housing including a frusto-conical valve seat for the valve ball. 18. The kit according to claim 15, wherein the valve member has a housing including a frusto-conical valve seat for the valve ball. 19. The kit according to claim 11, wherein the catheter further comprises an O-ring seal against the valve member. 20. The kit according to claim 13, wherein said retaining element includes a pull element which extends along said lumen and is secured to said lumen element housing by a retention device. 21. The kit according to claim 20, wherein said retention device includes a spherical member seated in a recess of said lumen element housing. 22. The kit according to claim 11, wherein said hand-operable connection members are configured to engage one another with a snap fit. 23. The kit according to claim 11, further comprising a retaining element having an insertion position in which, during entry of the lumen element into the bladder from the patient's skin through a lumen-sized hole, the retaining element also passes through the patient's skin and into the bladder through said same lumen-sized hole, said retaining element once inserted being expandable into a deployed position having a diameter greater than said lumen-sized hole to retain the lumen element in the bladder.
