title: The frequence of renal cell carcinoma in population of patients with kidney tumors.
abstract: BACKGROUND
  A kidney tumor is an abnormal growth within the kidney that usually occurs over a period of a time. Each tumor has its own characteristics and it is important to know what tumor the patient has so that the proper treatment can be administered. Kidney tumors can be benign or malignant. Symptoms of all types of kidney tumors are very similar and unspecific. The aims of study: a) To determine how many patients, who were clinically and radiologically diagnosed with kidney tumor, after surgical intervention, have histopathologicaly confirmed renal cell carcinoma; b) To compare number of female and male patients have histopathologicaly confirmed renal cell carcinoma; c) To compare numbers of patients with renal cell carcinoma who are older than 50 years with the ones who are younger than 50 years; d) To determine the most common risk factors for renal cell carcinoma; e) To determine the most common symptoms of renal cell carcinoma; f) To determine what was the most common stage of kidney cancer in the time when it was histopathologicaly confirmed.
  
  
  METHODS
  This study was observational, descriptive, retrospective study of renal cell carcinoma. The study consisted of 28 patients who were clinically and radiologically diagnosed with kidney tumor, which was surgically removed and histopathologicaly tested. All patients were surgically treated at the Urological Clinic of Clinical Centre University of Sarajevo from 1/1/2012 to 06/30/.2012.
  
  
  RESULTS
  from 28 patients with a kidney tumor 26 had RCC, the most of patients with RCC were older than 50 years (22 patients), there was 7 female and 19 male patients, the most common symptom was pain (10 patients), the most common risk factor, excluding age, was hypertension (11 patients), patients with RCC was usually diagnosed stage 4 Fuhrman (11 patients).
  
  
  CONCLUSIONS
  Doctors should give their intention to discover early symptoms of renal cell carcinoma and to do preventive exams and tests in the population of patients who have one or more risk factors for developing this disease. Early diagnose and appropriate therapy could reduce mortality and morbidity of the patients with renal cell carcinoma, and could also reduce costs of treatment.
