Renal cell cancer of the kidney

Renal cell cancer of kidney malignant tumor derived from epithelial the cortical layer of the kidney.
Among tumors of the kidneys, the most common (75-85%). Usually observed at the age of 40 - 60 years, most men; children renal cell cancer of the kidney happens very rarely. Running, inoperable tumors occur more often in women as the earliest symptom of renal cell cancer of the kidney - painless hematuria (see)- adopted by women for uterine bleeding.
Renal cell cancer of the kidney in the beginning can occur without obvious symptoms; classical triad - hematuria, pain, apparently tumors is rare. Hematuria may come suddenly, amid the General good status (asymptomatic hematuria). The intensity hematuria range from slight staining of urine blood to heavy bleeding with the presence of a worm-like clots. Hematuria may appear once or lasts several days and weeks; re hematuria can appear within a few days, months, and sometimes the year. Total asymptomatic hematuria should always call the suspected renal cell cancer of the kidney. In some cases of renal cell cancer of the kidney is observed only microhematuria, revealed at the analysis of urine.

To probe the renal cell cancer of the kidney is not always (in about half of cases). Pain in most cases blunt, are less acute, type renal colic, are observed in all patients. A very characteristic of renal cell cancer, kidney pain following hematuria (unlike kidney stones, at which pain precede hematuria). Low grade "groundless" temperature (rarely to increase the temperature to 38 degrees Celsius sudden chills) may be the first and only symptom of renal cell cancer of the kidney. In the study of blood, except acceleration ROHE (in some cases up to 30-50 mm in 1 hour), other specific changes do not detect. In atopiceski flowing cases of renal cell cancer of the kidney may be only the increase of temperature, acceleration ROHE, weight loss, deterioration of the General condition.
Renal cell cancer spreads kidneys mainly on venous ways (often metastases are found in the lungs, lymphatic nodes, bones, liver and brain), rarely in the lymph.
The main method of diagnosis of renal cell cancer of the kidney - detailed urological research, including retrograde pielografia (see), angiography (see) and other
All patients with suspected renal cell cancer of the kidney (even if there is only one total asymptomatic macrohematuria) should be sent to the hospital.
Treatment. The only method of treatment is nephrectomy (see). When there is widespread metastases after nephrectomy appoint anticancer drugs (e.g., tiofosfamid , and others).
