Background

The ureterostomy is one of important operation formulas for urinary stream diversion of patients with bladder cancer, and is the best choice for patients who perform radical cystectomy and have full-dissection of the affected side renal ureter. Patients at high risk of bladder cancer (elderly, severe medically related diseases) are also preferred for uretero-dermostomy due to the difficulty of withstanding too great trauma and possible intestinal complications. In addition, some malignant patients present with bladder symptoms that are difficult to control and are amenable to this procedure. Compared with the urinary flow diversion ileum output tract operation after the standard bladder total resection, the operation time of the ureter skin stoma is short, and the wound of a patient is small. However, the ureterostomy is prone to complications such as infection, ischemia, necrosis, stenosis, retraction, etc., which causes pain to the patient and increases medical expenses and economic burden.

The conventional single J tube indwelling after the traditional ureterostomy is different in indwelling time and replacing scheme, but has certain problems and disadvantages. The single J tube is kept for a long time, which is beneficial to improving drainage, but people who keep for more than 3 months are easy to cause concussion, obstruction, hydrops and infection of the upper urinary tract, and even difficult to pull out the tube; the single J tube cannot play a role in supporting and draining when the retention time is too short; the single J tube is replaced regularly (every 1-2 months) to realize the functions of expanding, supporting and draining and preventing the formation of calculus, but the guide wire is needed for replacing the single J tube, and the operation is needed by a doctor in a hospital, so that the economic burden of a patient is increased, and the risk of retrograde infection exists. At the joint of the nipple and the skin of the ureter skin stoma, the ureter stoma is easy to be narrowed due to the creeping of the skin.

The post-ureterostomy indwelling fixing bracket has the advantages of firm fixation, good elasticity, longitudinal extension, transverse deformation resistance, convenience in tube drawing and capability of preventing stones, upper urinary tract obstruction, water accumulation and infection.
