The rear end portion 11c of the kidney catheter body 11 from which a fine suture 47 (see Fig. 2) of the diarrhea is inserted in advance is formed of a metal containing a straight hollow tube as shown in Fig. 5 (1). The cannula 51a is inserted into the renal catheter body 11 and reaches the front end portion 11a of the kidney catheter body 11, and the flexion portion of the distal end portion 11a is corrected to a straight state in advance. Further, the suture thread 47 is placed outside the one end portion, and the other end portion is inserted from the rear end portion 11c of the kidney catheter body 11 to the distal end portion 11a, and extends from the opening 17a of the tapered portion 17 to the outside. The small hole 33 is again inserted into the renal catheter body 11 and extends from the rear end portion 11c to the outside. Such an operation is performed separately for each of the kidney catheter bodies 11 of the pair of renal conduits 3, 3. Next, after the center of the abdomen is cut longitudinally by the scalpel and the bladder and the kidney are exposed to the outside, as shown in FIG. 6, the sputum catheter M is formed by puncture the spur inlet M of the cover P of the penis P with a scalpel. The indwelling portion 27 of the 5 is located between the penis P and the foreskin K. When the puncturing inlet M is formed, the portion of the foreskin K which is slightly separated from the puncturing inlet M is cut by a scalpel to form a slit S which is larger than the lance inlet M in advance.

Next, a liquid medical adhesive is applied to the side surface of the endless belt 21 and the portion of the sheath K to surround the endless belt 21 and the cover K. Next, the taper portion 25 of the self-retaining portion 27 is inserted into the plate 49 having the same shape and material as the positioning member 23 via the slit opening S, and the wrapper K is sandwiched between the plate 49 and the endless belt 21. Further, by the frictional force generated by the contact between the outer peripheral portion of the connecting portion 29 and the inner peripheral portion of the plate 49 when the peripheral portion of the connecting portion 29 of the urination catheter body 19 is fitted, the core along the connecting portion 29 The relative movement of the connecting portion 29 and the plate 49 in the direction is regulated. Moreover, by imparting the force of the human hand exceeding the maximum value of the frictional force that can regulate the relative movement to the plate 49, the plate 49 is slid at the joint portion 29 to achieve relative movement therebetween. Next, the injection needle (not shown) inserted in the metal cover 53 including the straight hollow tube shown in FIG. 5 (4) is used to puncture the kidney together with the cover 53. The puncture is inserted into the renal pelvis cavity. Next, after the injection needle is pulled out from the cover 53 while keeping the cover 53 inserted into the kidney, the wire 55 shown in FIG. 5 (5) is inserted into the cover 53 and the wire is placed. 55 is inserted into the front end portion into the renal pelvis cavity. The wire 55 includes a member made of metal which is flexible and freely deflectable. Next, from the side of the front end portion 11a of the kidney catheter body 11 into which the cannula 51a is inserted, the rear end of the wire 55 is inserted into the cannula 51a until the front end portion 11a of the renal catheter body 11 enters the renal pelvic cavity of the kidney to make the renal catheter 3 Inserted along the wire 55. Next, after the distal end portion 11a of the renal catheter body 11 is left in the renal pelvis cavity and the wire 55 is pulled out from the renal catheter body 11, the cannula 51a is also pulled out from the renal catheter body 11. At this time, the lead wire 55 can also be drawn simultaneously with the insertion tube 51a. If it is confirmed that the distal end portion 11a is positioned in the renal pelvic cavity of the kidney, all of the four side holes 31 are positioned in the renal pelvic cavity, and then inserted into the renal catheter body 11 and exposed from the rear end portion 11c of the renal catheter body 11. The two external sutures 47 are simultaneously pulled by hand, and the front end portion 11a of the renal catheter body 11 placed in the renal pelvis cavity is curved in an arc shape.

Next, a medical adhesive is applied to the surface of the renal capsule and the side of the annulus 13 to adhere the surface of the renal envelope to the annulus 13 . Further, since the renal capsule is very soft and brittle, the renal capsule and the annulus 13 are temporarily fixed only by sutures. Then, by fixing the endless belt 13 on the surface of the renal capsule, the relative movement of the positioning member 15 fixed to the annulus 13 with respect to the kidney is prevented. As described above, since the suture 47 is completely removed from the renal catheter main body 11 after the end portion 11a of the renal catheter 3 is flexed by the suture 47, it is not necessary to leave the suture 47. Follow-up processing. Further, the suture line 47 is completely removed from the kidney catheter body 11 as a result of the front end portion 11a even if the front end portion 11a of the kidney catheter body 11 is not only capable of maintaining the shape of the arcuate buckling with its rigidity. It becomes easy to escape from the renal pelvic cavity of the kidney, but the annulus 13 to which the flange portion 15a of the positioning member 15 is affixed is fixed to the surface of the renal capsule, and the cylindrical portion 15b of the positioning member 15 and the renal catheter body The frictional force generated by the contact of the intermediate portion 11b of the 11 portion surely functions, so that the front end portion 11a of the renal catheter body 11 does not come out of the renal pelvis cavity. In this manner, the operation of leaving the renal catheter body 11 in the kidney is performed separately for the pair of renal catheters 3, 3, and the pair of renal catheters 3, 3 are appropriately placed in the left and right kidneys, respectively. Next, after the sleeve 9 is inserted into the end portion 11c of each of the kidney catheter body 11 and the rear end portion 19c of the urinary catheter body 19, respectively, the inner circumference of the rear end portion 11c of each of the kidney catheter bodies 11 is embedded. The peripheral portion of each connector 41 on one side of the relay adapter 7 is coupled to each of the kidney conduits 3 to the relay adapter 7, and the inner peripheral portion of the rear end portion 19c of the urination catheter body 19 is embedded. The urination catheter 5 is also connected to the relay adapter 7 at the outer peripheral portion of the connector 41 on the other side of the relay adapter 7. Next, the sleeves 9 inserted into each of the kidney catheter body 11 and the urinary catheter body 19 are moved toward the relay adapter 7 and moved along the two catheter bodies 11, 19, respectively, and each of the catheter bodies 11, 19 is placed. The connection portions of the rear end portions 11c and 19c and the respective connectors 41 of the relay adapter 7 are covered and fastened by the sleeve 9, respectively. Next, the relay adapter 7 to which the respective renal catheter 3 and the urinary catheter 5 are attached is sutured at the outer surface of the peritoneum by suture. At this time, the suture is inserted into the second adapter piece 37b by the state in which the flat outer surface of the second adapter piece 37b of the relay adapter 7 abuts against the outer surface of the peritoneum. The through holes 43 are sewn together, and the relay adapter 7 is stably fixed to the outer surface of the peritoneum. Further, the relay adapter 7 is initially positioned below the abdominal wall of a portion other than the portion that cuts the center of the abdomen by the sealing member 39 of the relay adapter 7 that is opposed to the abdominal wall. The front end is pressed and the skin of the abdomen of the part is raised. With the bulge of the abdomen, the position of the sealing member 39 of the relay adapter 7 with respect to the abdomen can be easily visually recognized. Finally, the abdominal opening operation of the cut opening S of the foreskin K and the cut opening of the abdomen by the scalpel is performed, and the operation of leaving the urinary bypass device 1 on the abdomen of the dog is finally completed. Further, in the above description, the operation procedure for the case where the animal is male is explained, and the operation procedure for the case where the animal is female is only the intravaginal portion of the indwelling portion 27 of the end portion 19a before the indwelling urination catheter 5 In addition to this point, it is sufficient to perform the same steps as the above-described operation steps. In addition, the order of the above-described operation steps is not limited to the above-described order, and can be appropriately changed without departing from the scope of the present invention. Further, in the above operation, when the renal catheter main body 11 of the renal catheter 3 is inserted into the renal pelvic cavity of the kidney, the method of using the cover 53 and the lead 55 is employed, but other methods may be employed instead. For example, it is possible to insert the puncture needle 51 into which the needle 51b is inserted in the cannula 51a into the renal catheter main body 11, and to puncture the kidney by piercing the kidney with the needle 51b protruding from the renal catheter main body 11 and the cannula 51a. The inlet is inserted into the renal pelvis cavity at the front end 11a of the renal catheter body 11. Further, the surface of the renal capsule and the adhesive force of the medical adhesive with each of the surface of the annulus 13 and the sheath K and the annulus 21 are reduced over time, but the biological tissue is immersed in each annulus. 13, 21, and the surface of the renal capsule and the surface of the annulus 13 and the sheath K and the annulus 21 are firmly consolidated, respectively. Thereby, the positioning member 15 can be firmly fixed to the surface of the renal capsule via the endless belt 13. Further, when the eye is blocked in the renal catheter main body 11 or in the urination catheter main body 19, the skin and the abdominal wall of the abdomen are penetrated by the injection needle of the syringe filled with the washing solution such as physiological saline solution, and the injection needle is inserted. The sealing member 39 of the relay adapter 7 injects the cleaning liquid into the kidney catheter body 11 and the urination catheter body 19 via the cavity 45 of the relay adapter 7. Thereby, the obstacle that hinders the circulation of the urine can be removed, and the circulation in the renal catheter main body 11 and the urination catheter main body 19 can be kept good. Further, in contrast to this, the collected urine can also be inspected by suction and collection of urine through a cavity 45 of the relay adapter 7. The injection of such a washing liquid and the collection of urine are performed periodically. Further, the small hole of the sealing member 39 formed by the injection needle of the syringe is occluded by the elastic force of the sealing member 39 when the injection needle of the syringe is pulled out, and is liquid-tightly sealed. . According to the urination catheter 5 of the embodiment of the present invention as described above, since the front end portion 19a of the urinary catheter 5 is provided with an indwelling portion 27 which can be left between the penis P and the foreskin K or in the vagina; and the connecting portion 29, respectively When one end portion of the indwelling portion 27 and the intermediate portion 19b is connected, even when the urethral opening of the bladder is blocked due to cancer or other urinary system diseases, it is ensured that the urine is used without the bladder puncture. The liquid drains the urinary tract outside the organism. Further, both end portions of the connecting portion 29 of the front end portion 19a of the urination catheter 5 are formed to be connected to each of the end portions of the indwelling portion 27 and the intermediate portion 19b in an L shape, and the indwelling portion 27 is left in place. Since it is between the penis P and the foreskin K or in the vagina, the indwelling portion 27 is not unnecessarily stimulated by the indwelling portion 27 to secure the urinary tract, thereby causing discomfort or damage. Further, since the connecting portion 29 and the indwelling portion 27 are connected in an L shape, the indwelling portion 27 is left between the penis P and the foreskin K or the vagina by inserting the front end portion 19a of the urination catheter 5 through the puncture inlet M. In the inside, the inflection portion 27 formed in the L shape can be prevented from coming out of the puncture inlet M. Further, since the urination catheter 5 is provided with a disk-shaped cloth loop band 21 that is fitted to the joint portion 29 of the distal end portion 19a, the cloth loop 21 is adhered to the foreskin K or the tissue outside the vagina. The front end portion 19a of the urinary catheter 5 can be surely fixed to the portion of the living body to be fixed via the endless belt 21. Further, since the urination catheter 5 is provided with a disk-shaped resin plate 49 that can be fitted to the connection portion 29 of the distal end portion 19a, the foreskin K or the foreskin of the vagina can be sandwiched by the plate 49 and the annulus 21. The front end portion 19a of the urinary catheter 5 is stably fixed to the portion. Further, since the outer peripheral surface and the inner peripheral surface of the indwelling portion 27 are covered with the antibacterial material, harmful bacteria can be prevented from intruding into the living body from the outside through the front end portion 19a of the urination catheter 5. The above-described embodiments are for explaining an example of the present creation, and the present invention is not limited to the above-described embodiments, and may be within the scope of the essence of the creation or the idea of not reading the scope of the self-authorization registration request and the overall reading of the specification. Appropriate changes, such modified kidney catheters and urinary catheters are also included in the technical scope of this creation. For example, the positioning member 15 of the kidney catheter 3 of the above-described embodiment is configured by the flange portion 15a and the tubular portion 15b, and the like. However, the present invention is not limited thereto, and the flange portion 15a and the tubular portion 15b may be The cylindrical portion 15b may be omitted in a state of being separated from each other. In the case where the cylindrical portion 15b is omitted, the frictional force generated by the contact between the inner peripheral portion of the flange portion 15a of the positioning member 15 and the outer peripheral portion of the intermediate portion 11b of the renal conduit body 11 is regulated along the intermediate portion 11b. The relative movement of the flange portion 15a and the intermediate portion 11b in the direction of the core may be sufficient. Further, it is possible to configure the distal end portion 19a of the urination catheter body 19 of the urinary catheter 5 of the above-described embodiment as shown in Figs. 7 and 8 . It is to be understood that the same effects and effects as those described in the above embodiments can be exhibited in the variations shown in the drawings. In FIG. 7 and FIG. 8 , the urination catheter main body 19 is displayed for convenience of illustration, and one of the longitudinal direction is omitted, and the same or equivalent members and parts as those described in the above embodiments are used. The same reference numerals will be given to the detailed description, and the differences from the above-described embodiments will be mainly described in detail. The urination catheter body 19 of the above embodiment has a U-shaped end portion of the distal end portion 19a and the intermediate portion 19b connected to the distal end portion 19a. Alternatively, as shown in Fig. 7, the urinary catheter body 19 may have a distal end portion. One end of the intermediate portion 19b connected to the front end portion 19a is formed in a crank shape. Further, as the shape other than the crank shape, the indwelling portion 27 of the front end portion 19a of the urination catheter main body 19 may be formed into a shape as shown in Fig. 8 . 8(1) and (3), the indwelling portion 27 is formed so as to extend in a direction substantially perpendicular to the axis of the connecting portion 29 of the distal end portion 19a, and then draw a circle around the axis. On the other hand, as shown in Figs. 8(2) and (4), the indwelling portion 27 extends in a direction substantially orthogonal to the axis of the connecting portion 29 of the distal end portion 19a, and then extends along the extending portion thereof. An elliptical buckling is formed on the imaginary plane of each of the cores of the connecting portion 29. By forming the circle or the ellipse in this manner, the indwelling portion 27 can be more easily detached from the puncture inlet M than the L-shaped buckling portion of the front end portion 19a of the urination catheter body 19 of the above-described embodiment. Further, as shown in Figs. 8(2) and (4), the portion of the indwelling portion 27 which is formed by the elliptical buckling is along the respective cores of the intermediate portion 19b which is connected to the connecting portion 29 and the connecting portion 29. In the imaginary plane, the ventilating catheter body 19 is formed in a two-dimensional shape (flat shape), and the urination catheter body is housed in the same manner as the urination catheter body 19 shown in FIG. The volume does not have to increase at 19:00 Further, since the front end portion 19a side of the urination catheter body 19 is formed in a two-dimensional shape, the urination catheter body 19 includes a member having flexibility, so that the indwelling portion 27 is left between the penis P and the foreskin K or in the vagina. Then, the elliptical buckling portion is corrected so as to be sandwiched between the penis P and the foreskin K or the intravaginal indwelling portion 27 so as to be directed substantially perpendicular to the axis of the connecting portion 29. Further, the urination catheter 5 of the above-described embodiment and its modification includes the endless belt 21, the positioning member 23, and the plate 49. However, the present invention is not limited thereto, and at least one of the positioning member 23 or the plate 49 may be omitted, or may be omitted. All of the endless belt 21, the positioning member 23 and the plate 49. It is assumed that even if the positioning member 23 and the plate 49 are omitted, the body tissue of the foreskin K or the outside of the vagina is appropriately fixed by the endless belt 21, and the front end portion 19a of the urinary catheter 5 is surely fixed to the living body to be fixed. Part. In addition, even if all of the endless belt 21, the positioning member 23, and the plate 49 are omitted, since the indwelling portion 27 and the connecting portion 29 are connected in an L shape, the indwelling portion 27 is prevented from coming off by the L-shaped bent portion. Therefore, the front end portion 19a of the urination catheter 5 is detached from the portion of the living body to be fixed. Further, in the urination bypass device 1 of the above embodiment, the pair of renal conduits 3, 3 and one urination catheter 5 are respectively connected to the relay adapter 7 having three connectors 41, but instead of this, Two urinary bypass devices each connecting the renal catheter 3 and the urination catheter 5 to the relay adapter 7 including the pair of connectors 41 and 41, respectively, can be used. In this case, it is provided that each of the renal conduits 3 of each of the urinary bypass devices is left in a pair of right and left kidneys, and on the other hand, each of the indwelling portions 27 of each of the urinary catheters 5 of each of the urinary bypass devices is left.
