title: [The choice of surgical modality to treat patients with staghorn nephrolithiasis].
abstract: OBJECTIVE
  Improvement in the results of the treatment of patients suffering from staghorn and multiple nephrolithiasis, using open method of surgery and a retrospective analysis of the surgical data.
  
  
  METHODS
  There was executed asurgical treatment of the 730 patients with staghorn and multiple nephrolithiasis in the period from 1998 to 2012. 480 of the patients had one-sided staghorn stones and 250 of them had double-sided staghorn stones. Age of the patients varied from 4 to 76 years old (average - 49). There were 351 men (48,0%) and 379 women (51,9 %). 290 (39,8%) patients had only staghorn stones, but 440 (60,2%) patients suffered from staghorn stones combining with multiple ones.
  
  
  RESULTS
  There were executed 1065 surgical operations at the 730 patients. There was used pyelotomy and nephrolithotomyfor the purpose of the ablation of stones. Nephrostomy was placed on the right of the 116patients (15,8%), on the left - 93patients (12,7%), pyelostomy on the right - 46 patients (6,3%), on the left - 31patients (4,2%), intrarenalstent on the right - 181 patients (24,7%), on the left - 167patients (22,8%), stent and nephrostomy on the right - 29 patients (3,9%), on the left - 6 patients (0,8%). Surgical operations of 184 patients (25,2%)fulfilled throughcross-clamping of the nephritic artery.Cross-clamping time of the nephritic artery in average was 16.5 minutes (5-50), average duration of the surgical operation - 2,6 hours (1,5-6), intraoperative hemorrhage - 110 ml (50-300). During the re-examination there was found that 175 patients (23,9%) had recurrent stones.During first ten years after operation there were found recurrent stones at 238 patients (32,6%), 100 (13,6%) of them had the second operation.
  
  
  CONCLUSIONS
  Taking into account that minimally invasive methods of the staghorn and multiple nephrolithiasistreatment is ineffective and demand a few courses of medical treatment, open surgical operations still have a leading positions as they create extensive possibilities for the favorable and safe revision of the kidney during ablation of stones.
