title: [Principles of surgical treatment of patients with renal tumor and coexistent contralateral kidney stone].
abstract: OBJECTIVE
  To determine the treatment strategy for patients with renal tumors and coexistent contralateral kidney stone.
  
  
  METHODS
  From 2006 to 2015, 1380 and 4833 patients underwent surgery for renal tumours and kidney stones, respectively. The combination of stone disease and renal tumor was found in 159 (11.5%) patients, of whom 61 patients had indications for surgical treatment of both diseases at the time of hospital admission. Of these, 17 (27.9%) patients (8 men and 9 women) had renal tumors and coexistent contralateral kidney stone.
  
  
  RESULTS
  Initial surgery for stones was performed in 10 (58.8%) cases. In the remaining 7 (41.2%) patients, the first operation was for renal tumors. None of the patients underwent simultaneous removal of the contralateral kidney stone. The most common types of treatment for kidney stones were percutaneous nephrolithotripsy and extracorporeal shock-wave lithotripsy. Twelve (70.6%) patients underwent partial nephrectomy, the remaining 5 (29.4%) had nephrectomy. In total, 17 patients with renal tumors and coexistent contralateral kidney stones were treated using 11 different treatment combinations. These results show the need to define treatment strategies for each patient individually, taking into account all possible factors.
  
  
  CONCLUSIONS
  In patients with renal tumors and coexistent contralateral kidney stone, the basic principle of surgical treatment is to perform an organ-sparing surgery, given technical feasibility and normal function of kidney, affected by the tumor.
