Abstract

A urinary tract irrigating assembly for flushing a TURP-treated prostate gland having a surgically created central cavity. The assembly includes an elongated catheter having a drain port for draining the bladder contents; a discharge port for discharging prostate-irrigating fluid into the cavity; and a second drain port for draining spent prostate-irrigating fluid and other fluids from the cavity. Positioning means are provided for positioning the catheter with the first port located in the bladder and the second and third ports located within the prostate cavity. In use, a predetermined amount of irrigating fluid at predetermined time intervals is discharged into the prostate cavity through the discharge port while draining urine through the first drain port and spent prostate treating agent through the second drain port.

Claims

1. A method of irrigating and draining a urinary tract having a bladder and a prostate cavity, the method comprising the steps of:

(a) providing an elongated catheter having a bladder drain conduit, an irrigation conduit, and a prostate drain conduit;

(b) draining the contents of the bladder through the bladder drain conduit;

(c) irrigating the prostate cavity with fluid discharged through the irrigation conduit; and

(d) draining the irrigating fluid from the prostate cavity through the prostate drain conduit.

2. The method of claim 1, wherein the step of providing an elongated catheter includes providing an elongated catheter having a bladder drain conduit defining a bladder drain port.

3. The method of claim 1, wherein the step of providing an elongated catheter includes providing an elongated catheter having an irrigation conduit defining an irrigation port.

4. The method of claim 1, wherein the step of providing an elongated catheter includes providing an elongated catheter having a prostate drain conduit defining a prostate drain port.

5. The method of claim 1, further comprising the step of positioning the catheter within the urinary tract.

6. The method of claim 5, wherein the step of positioning the catheter includes inflating a balloon positioned along the length of the catheter.

7. The method of claim 1, further comprising the step of positioning the catheter within the urinary tract so that the bladder drain conduit is in fluid communication with the bladder, and so that the fluid discharge conduit and the prostate drain conduit are in fluid communication with the prostate cavity.

9. The method of claim 1, further comprising the step of connecting a drain bag to the bladder drain conduit.

10. The method of claim 1, further comprising the step of connecting a drain bag to the prostate drain conduit.

8. The method of 1, wherein the step of irrigating the prostate cavity includes delivering a measured amount of fluid according to a pre-determined time schedule.

11. A method of irrigating and draining a urinary tract having a bladder and a prostate cavity, the method comprising the steps of:

(a) providing an elongated catheter having a drain conduit defining a first port for draining the bladder and a second port for draining the prostate cavity, and having an irrigation conduit;

(b) draining the contents of the bladder through the drain conduit;

(c) irrigating the prostate cavity with fluid discharged through the irrigation conduit; and

(d) draining the irrigating fluid from the prostate cavity through the prostate drain conduit second port.

12. The method of claim 11, further comprising the step of positioning the catheter within the urinary tract.

13. The method of claim 12, wherein the step of positioning the catheter includes inflating a balloon positioned along the length of the catheter.

14. The method of claim 11, further comprising the step of positioning the catheter within the urinary tract so that the first port of the drain conduit is in fluid communication with the bladder, and so that the second port of the drain conduit is in fluid communication with the prostate cavity.

15. The method of claim 11, further comprising the step of connecting a drain bag to the drain conduit.

16. The method of claim 15, further comprising the step of collecting urine and irrigant discharge in the drain bag connected to the drain conduit.

17. The method of claim 11, wherein the step of providing an elongated catheter includes providing a catheter having a one-way valve positioned within the catheter between the first port and the second port.

18. The method of 11, wherein the step of irrigating the prostate cavity includes delivering a measured amount of fluid according to a pre-determined time schedule.

19. The method of flushing with a prostate irrigating fluid a TURP-treated prostate gland having a surgically-created central cavity, the method comprising providing catheter means connected to a source of irrigating fluid under pressure and a receptacle for receiving spent treating fluid, the catheter means having an irrigating fluid discharge port and a spent fluid drain port, arranging the catheter means in the urethra with both ports operatively positioned in the prostatic cavity, discharging into the cacity through the discharge port a predetermined amount of irrigating fluid at predetermined time intervals, draining spent irrigating fluid from the cavity through the drain port, and transmitting the same to the spent treating fluid receptacle.

20. The method of claim 19 including the step of arranging the catheter means with the drain port proximal to the discharge port and flushing the cavity in the proximal direction.
