Abstract

The invention discloses a novel ureter urine collector and belongs to the field of medical instruments. The novel ureter urine collector comprises an outer sleeve; an inner conduit, wherein one end ofthe inner conduit extends into the outer sleeve, and a push-pull structure is arranged on the outer surface of the inner conduit; and an expansion hose, wherein the expansion hose connects one end ofthe outer sleeve and one end of the inner conduit extending into the outer sleeve. The novel ureter urine collector can collect the ureteral urine of the intraoperative patient, avoid the transfer ofthe tumor cell in the urine to the bladder mucosa, and confirm the presence of the tumor cell by performing the subsequent exfoliative cytological pathological examination on the collected urine, which further provides strong evidence for the tumor metastasis theory; the novel ureter urine collector is simple in structure, convenient in operation, low in production cost and suitable for popularization.

Description

technical field [0001] The invention relates to a novel ureter urine collector, which belongs to the field of medical instruments. Background technique [0002] Radical nephroureterectomy combined with bladder sleeve resection is the standard treatment for upper tract urothelial carcinoma, however, after radical resection, up to 40% of patients will experience bladder recurrence, which seriously affects the survival and quality of life of patients , existing studies suggest that the implantation of tumor cells in the upper urinary tract may be a potential risk factor for bladder recurrence. Its clinical evidence can be summarized in the following three aspects: first, about 70% of bladder cancer patients develop within 1 year after nephroureterectomy; second, the incidence of bladder cancer after diagnosis of upper tract urothelial carcinoma is 35% , while the incidence of upper tract urothelial carcinoma after diagnosis of bladder cancer is only 5%; third, a single dose of...
