Squamous cancer of the kidney - the distinctive features of pathology

Squamous cell carcinoma of kidney, usually refers to chronic inflammatory processes in the urinary system or an infectious lesion.Generally it occurs in age from 40 to 60 years mostly in males.Both kidneys are damaged almost evenly.

etiological factors are not fully established. metastases in cancer pelvis hematogenous spread, lymphogenous and subepithelial way. During the morphological examination of the ureter in a patient with cancer of the pelvis malignant cells are found beneath the mucosal lymph nodes.

What are the symptoms of the disease manifest?

Asymptomatic I observed in 10 - 25% of cases.Most affected primarily develops total hematuria, which is almost always accompanied by pain in the lumbar region due to blockage of the ureter by a blood clot.

In 10% of patients have the classic triad of symptoms - a hematuria, pain and palpable tumor - all this says about the vastness of the process and the treatment of poor prognosis of the disease.

The activity of the disease and its prevalence says

weight loss, weakness and loss of appetite.

How is the diagnosis of pathology

Three times cytological diagnosis of urine sediments allows us to establish the presence of atypical cells only in 30% of cases.To obtain more accurate data used wash water of the renal pelvis and ureter with urine catheterization.

excretory urography in oncology in the pelvis plays an important role in comparison with the survey tumors in organ parenchyma.The tumor of the renal pelvis is manifested in violation of filling location neoplasms contrast fluid.In violation of a discharge of urine occurs hydronephrosis transformation.To verify the information received is conducted retrograde ureteropyelography.

This is important! If the implementation of excretory urography is suspected the presence of a tumor, the need to perform computed tomography with contrast medium administration and slice location at the level of the pelvis.When CT is required to identify the density of the tumor and its change with the introduction of contrast.

In the case of the spread of tumors in the kidney parenchyma for the differential diagnosis of primary tumors with parenchyma realized angiography.

ultrasound renal pelvis in the formation of a tumor does not give enough information in the absence of hydronephrosis.Simultaneously this method is the differential diagnosis of primary tumors of the pelvis.

Often, the tumor can affect the bladder and ureter, requiring endoscopic examination of the mucosal surface of the urinary channel.

How is the treatment after diagnosis

Nefrureterektomiya with excision of the bladder makes it possible to prevent the development of an active tumor processes in cancer of the renal pelvis.Sometimes the intramural department in the ureter and removing exposed during open surgery and endoscopy.

This is important! operations with smaller volume can cause relapse and re-formation of a tumor, as well as the generalization of the pathological process.

sparing surgery is warranted for those patients who have only one kidney is affected, for patients with bilateral lesions or in clear violation of the functioning of the body.Oncology renal pelvis is often characterized by relapses, so patients with this diagnosis requires careful monitoring by a specialist.

When organizing the treatment of patients with a common form of cancer in the renal pelvis in the complex therapeutic measures commonly used chemotherapy or radiotherapy.
