The surgery of rectal cancer can cause and urinate _'s treatment of the obstacle
Function and sexual dysfunction are common complications to urinate after the rectal cancer operation, should cause enough attention for the life quality after improving patient's operation. This text introduces the postoperative function obstacle of urinating especially.
Generally think its main reason that happens results from damaging and controlling the basin nerve that has urinated at present, often clean the range with the lymph node in the pelvis and is directly proportional to in intensity of the obstacle of urinating on clinic.
Basin urinate, have to belong to nerve and basin viscera nerve to belong to parasympathetic nerve in front of the orthosympathetic sacral bone close relation in the nerve, the two participate in forming the main component of the basin clump, send out the branch to rectum, bladder, prostate, spermatic cord, seminal vesicle gland, uterus and vagina,etc.. The function is to finish by the bladder wall and shrink, expansion of sphincter to urinate. Orthosympathetic spreading is excited, can strengthen tense degree of sphincter, stop urinating, so the nerve is also called storing the nerve of urine before the sacral bone. Spreading that excited of parasympathetic nerve, can cause the wall smooth muscle of bladder (force the skin of urine) Shrink and the inner sphincter is relaxed, contribute to urinating, so the basin viscera nerve is also called urinating the nerve.
After the nerve, basin viscera nerve and a group of people or things of basin suffer and damage to different extent before the sacral bone, in clinic can appear by weight - urinate by obstacle. Clinical experience brief on, can make in operation nerve and basin viscera nerve avoided damaging in front of the sacral bone, will reduce or avoid urinating the emergence of the obstacle. Nerve by the intersection of belly and the intersection of aorta and underpart and sympathetic to do 3, 4 the intersection of waist and the intersection of waist and the intersection of viscera and nerve that section tell, participate in forming of clump in front of the sacral bone, this neural clump crosses over the branching of aorta to punish for the nerve of left and right lower abdomen, and fall along the hypogastric artery, enter the intersection of basin and clump above back pelvis, therefore and from heartbroken artery, vein under being membrane in the intersection of operation and ligature, while dissociating second form and forming the mesenterium, stripping operation should go on among peritoneum and membrane of muscle. Neural generally from side to side the branch part should be lower than branching of aorta, it is easy to distinguish that it is stripped and arrested blood carefully so long as careful.
The prevention key to the obstacle is the levels of range and stripping excised to urinate after the operation, it is only tight to excise rectum, the nerve, basin viscera nerve and basin clump before not damaging the sacral bone in the operation close to the rectum wall, urinate after the operation and the sexual dysfunction incidence is extremely low. However, rectal cancer is often soaked outside, strip and excise the small very difficult purpose to achieve the effecting a radical cure excision of the range, main position that should be that the effecting a radical cure excision will be placed on treating all the time.
