Kidney tumors

Tumor of the kidney is about 3% of all tumors in adults and approximately 30% in children. They occur in adults aged 40-60 years and in children more often in the age of 6 years. Men tumors of the kidney are significantly more likely than women. Benign tumors of the kidney are rare.
The absolute majority of all malignant tumors of the kidneys is gipernefroidnyi cancer of the kidney. Less common adenocarcinoma, Scherr and alveolar cancer, sarcoma of the kidney.
Clinical signs of malignant tumors of the kidney are manifested by low back pain, hematuria, accelerated ROHE, increased body temperature; the tumor is palpated in hypochondrium. Diagnose kidney tumor with the help of x-ray examinations: excretory urography, retropreparation (see Pneumotropica), retrograde pielografii. In recent years great importance in the diagnosis of tumors P. acquired renal angiography, which allows to detect even small size of the tumor. In the diagnosis of kidney tumors and metastases important isotope study - scan.
Tumors of the renal pelvis are much less common tumors of the renal parenchyma. Among tumors of the renal pelvis is dominated by epithelial (papillary) cancers. In appearance they resemble cauliflower and base tumors infiltrates the wall of the pelvis. Are papillary tumors usually in the transition region pelvis into the ureter and in half of all cases metastasize to the urethra or urinary bladder. Often there is simultaneous destruction of papillary tumors of the renal pelvis, ureter, and bladder.
The main clinical sign of tumor pelvis is hematuria, often with clots with worm-like appearance. Pain in the kidneys do not arise often and are sometimes the nature of renal colic caused by the rupture of a blood clots in the urine. Breaking the outflow of urine from the kidneys, tumors of the renal pelvis can lead to the formation of hydronephrosis (see).
Diagnostics of tumors of the renal pelvis is difficult and requires a wide urological examination including cystoscopy, intravenous urography, the retrograde pyelography, urine atypical cells.
During cystoscopy at the time hematuria you can determine the source of bleeding and to see the appearance of the mouth of the ureter vermiform blood clot. You can also detect metastases of papillary tumors pelvis into the lower part of the ureter, which hangs in the bladder as papillary education.
Excretory urography allows you to define hydronephrosis or filling defect in the pelvis.
Children in overwhelming majority of cases observed Wilms tumor - mixed tumor of the kidney. Wilms tumor felt in the abdomen, often swelling visible to the eye.
Palpable tumor is defined as round or oblong education with a smooth or rough surface. The larger size of the tumor occurs compression of the great vessels and there are advanced subcutaneous veins of the anterior abdominal wall. Swelling, rising, can cause pain and hematuria. Large tumor can cause compression of the organs of the gastrointestinal tract and diarrhoea disorders - vomiting, constipation and phenomena of intestinal obstruction. When diagnosing tumors Villmsa use x-ray examination.
Hematuria with Wilms tumor is a sign of germination in her pelvis and can have profuse character. The tumor grows quickly, metastasizes and in the first year after the appearance of the tumor results in death.
Treatment of kidney tumors online - with gipernefroidnyi cancer make a removal of the kidney (nephrectomy) together with a fat capsule and perinephral fiber. Discovered during the operation enlarged lymph nodes are removed.
When tumors of the renal pelvis produce a total nephroureterectomy - remove the kidney with the ureter and the area of the bladder wall and the mouth of the ureter.
Wilms tumor is treated promptly, using also radiation therapy, as a tumor refers to a group of radiosensitive. Radiation treatment before surgery (to reduce the size of the tumor and inhibit the growth of tumor cells), and after removal of the kidney with perinephral fiber, to eliminate individual tumor cells left in renal bed.
With surgical diseases of the kidneys in the complex treatment includes dietary treatment, which in various diseases has some differences. The General is full, vitamin-rich foods with the exception of annoying seasonings and spices; for a number of diseases - salt restriction and proteins.

Tumor of the kidney is about 3% of all cancers in adults and approximately 30% in children. In men, they are 2 times more often than women. Adult kidney tumor observed in the age of 40-60 years old, and children from 6 months up to 5-6 years. Tumor on can be primary or secondary, the latter is more often metastatic or tumor invasion of neighboring organs.
It is customary to distinguish tumors of the kidney (renal parenchyma), and tumors of the renal pelvis.
Tumors of the kidney. Benign tumors of the kidney are rare and often occur without the expressed clinical symptoms. Only large size benign tumors of the kidneys appear hematuria and pains in the lumbar region. Among malignant tumors P. more common gipernefroidnyi cancer (see renal cell cancer of the kidney). Described cases of multiple malignant tumors P. various histological structure: squamous cell carcinoma and leiomyosarcoma, cancer and rhabdomyosarcoma. Malignant tumors of the kidneys in adults proceed with the same clinical signs that and renal cell cancer: a total of painless hematuria, apparently swelling, pain in the lumbar region, increased body temperature, accelerated ROHE, etc. unlike vaginal cancer, mozgoviy cancer P. often metastasizes to the lungs, liver and less in the bone. In the diagnosis of tumors P. along with excretory urography, retrograde pyelography, Pnevmostroimashina great place belongs renal angiography.
This technique allows for the detection of the tumor is very small dimensions. Treatment of tumors P. surgery.

Tumors of the renal pelvis there are a lot more rare tumors of the renal parenchyma and account for about 12% of all tumors of the kidney and upper urinary tract. Tumors of the renal pelvis are connective and epithelial. Connective-tissue tumors are extremely rare. Epithelial tumors of the renal pelvis occur much more frequently. Morphologically distinguish benign papillomas, papillary (perekhodnocletocny), squamous cell carcinoma, solid, sliseobrazutee and other forms of cancers. Division of papillary tumors of the renal pelvis on benign and malignant very conditional. Histological examination papilloma on production cuts detected at the base of the tumor sites atypical structure that indicates the transition of adolescents into cancer.
About 80-90% of all tumors of the renal pelvis are papillary tumors. Macroscopically they resemble cauliflower and consist of short CVS. More often papillary tumors are on a broad basis, at least on the leg. The thicker the basis of the tumor, the more data to suspect its malignancy. The most frequent localization of tumors of the renal pelvis - pelvis-ureter segment. Much less frequent papillary tumors in renal cups. The main symptom of tumors of the renal pelvis is totally painless hematuria. When the location of the cancer in the pelvis-ureter segment due to violations of the passage of urine occurs quickly hydronephrosis, pain in the lumbar region and probed enlarged kidney.
Metastasis of tumors of the renal pelvis depends on their structure. Papillary cancers metastasize in the lower urinary tract: the ureter, urinary bladder. The spread of tumor cells occurs through the lymph system and interstitial spaces. Squamous cell carcinoma of the pelvis often metastasizes to the liver, lungs, bone, prerenalnaya and paraaortal lymph nodes.
Diagnosis of tumors of the renal pelvis is based on the clinical picture, data cystoscopy, cytological examination of urine sediment and results of x-ray examination. Cystoscopy allows you to set the source hematuria and presence of metastases in the intramural Department of the ureter and urinary bladder (see Cystoscopy). The most important method of diagnostics of tumors of the renal pelvis are excretory urography and retrograde pyelography. On programmah possible to detect hydronephrosis and pyelogram with liquid by contrast agent - filling defect. Pyelogram must be made in different projections, which allows to differentiate tumors of the renal pelvis with x-ray negative stones - urates. On pyelogram, made in different projections, filling defect in the tumors is uneven eaten paths, and do not shift.
Treatment of tumors of the renal pelvis only online. Proceeding from the possibility of metastasis these tumors in the lower urinary tract, radical surgery consists of nephroureterectomy and resection of the bladder wall at the location of the ureter mouth. The results of surgical treatment of the most favorable in papillary tumors. After radical surgery patients live 3-5 years or more. The patients after the operation should be under constant surveillance.
