Abstract

The invention relates to the field of cell pathology detection, in particular to a method of extraction and flaking of body fluid cells for checking bladder cancer. The extraction method comprises a sampling process and a treatment process. According to the method of extraction of body fluid cells for checking bladder cancer, urine sediment is broken and decomposed without damage, the problems that urine cells cannot be stored for a long time and the quantity of the cells is small due to the fact that the urine is autolyzed after leaving the human body for 2 hours are solved, the urine samplecan be stored for 7-10 days, the problem that the inspection turnover time is not enough is thoroughly solved, and the non-invasive detection can really benefit the public. The first morning urine with the most abundant diagnostic information and the most urinary sediments is adopted so that exfoliated cells can be completely dissociated from the urinary sediments, more than 5000 cells can be collected from the first morning urine and the sampling quantity, quality and detection success rate are greatly improved.

Description

technical field [0001] The invention relates to the field of cytopathological detection, in particular to a method for extracting and preparing slices of body fluid cells for checking bladder cancer. Background technique [0002] Bladder cancer refers to malignant tumors that occur on the bladder mucosa. It is the most common malignant tumor of the urinary system and one of the ten most common tumors in the whole body. It accounts for the first place in the incidence of urogenital tumors in my country, and ranks second in the West after prostate cancer. In 2012, the incidence rate of bladder cancer in the national tumor registration area was 6.61 / 100,000, ranking ninth in the incidence rate of malignant tumors. Bladder cancer can occur at any age, even in children. Its incidence rate increases with age, and the peak age is 50-70 years old. The incidence of bladder cancer in men is 3-4 times that of women. About 90% of bladder cancer patients initially present with hemat...
