Early symptoms of ureteral tumors?

summary

When it comes to malignant tumor, it is a kind of disease that is relatively difficult to cure. Many people will think of lung cancer, liver cancer, gastric cancer, cervical cancer, prostate cancer, colorectal cancer... But do you know? In the family of malignant tumors, there is also a kind of malignant tumor in the ureter, known as urothelial carcinoma, and it is often ignored. Many people can't cure for a long time, not because they can't cure well, but because they don't understand. Let's introduce the early symptoms of ureteral tumor?.

Early symptoms of ureteral tumors?

First, urothelial carcinoma is one of the most common ureteral tumors. When blood flows through the kidney, uric acid, urea, water and other substances will form urine under the action of nephron (the basic unit of kidney, including renal corpuscle and renal tubule). Urine from the calyces, pelvis through the ureter to the bladder, in this process, urine will contact with the urothelial cells, if the urine contains some carcinogens, and affect the urothelial cells, so that the urothelial cells have a gene mutation, it will lead to urothelial cancer.

Second, like most ureteral tumors, urothelial tumors are easy to be ignored because of their small size and hidden symptoms. Generally speaking, urothelial cancer occurs mostly in the middle-aged and elderly people. If the middle-aged and elderly people have recurrent and painless "gross hematuria" (hematuria is called when the urine contains a certain amount of red blood cells, microscopic hematuria is called when the red blood cells can only be found under the microscope, and gross hematuria is called when the flesh eye can see it), they should be vigilant, If accompanied by recurrent renal colic, then immediately to the hospital for examination. Examination methods usually include ultrasound, intravenous urography, CT urography, urinary magnetic resonance imaging, cystoscopy, ureteroscopy and so on; Ureteroscopy can determine whether there is space occupying lesion in the ureter (it means that there is an extra object in the examined part, which can compress and displace the surrounding tissue).

Third: once diagnosed with urothelial carcinoma, patients should follow the doctor's advice and receive timely treatment, including radical operation for ureteral carcinoma.

matters needing attention

It is worth mentioning that the traditional open radical operation for ureteral cancer is more traumatic, but with the development of laparoscopic technology and surgical robot technology, the operation is gradually refined, standardized and scientific, and the treatment effect is also gradually improved, which can make patients get greater benefits.
