   My uncle underwent the surgery of kidney cancer in October last year. And, the surgery was successful. So, I explain the kidney cancer.  

  Do you know the tissue of kidney? Kidney is consisted of renal parenchyma and renal pelvis. Renal parenchyma make the urine. And the urine made in renal parenchyma is collected in the renal pelvis. After that the urine is sent to the bladder, passing through the ureter for excretion.

   Then, do you know the symptoms of kidney cancer? First is hematuria which can be seen with the naked eye. Next is pain in the waist, back and flank. If the ureter was clogged with blood or the cancer has spread to the surrounding, this pain can be caused. These pains are similar to the ureteral stones and these will be disappear or happening suddenly. Furthermore, sometimes urination pain and frequent urination occurs.

   When the ureter is clogged with cancer, urine accumulates in the kidneys- this is called hydronephrosis-. If this continues for a long time, kidneys may not function- this is called non-functional kidney-. Usually,people have two kidneys,so even if one of the kidney isn’t functioning, the other kidney will compensate for the function. Therefore, the symptoms such as short urine and swollen body don’t occur so many like renal failure.

   These days, ultrasound check which is called echocardiography in general is made wide. So while there is no special symptoms, the number of kidney cancer which is discovered in such screening has been increasing. In addition, when the thorough examination is made for the water nephropathy, kidney cancer is sometimes found. My hope is that the number of people who is suffering from cancer will be decreasing by early detection.

Thank you.
