The present paper demonstrates the various methods in surgical treatment of complicated nephrolithiasis. The techniques of extended intrasinusal pyelocalicotomy, multiple radial nephrotomies, classic anatrophic nephrotomy, doppler-guided nephrotomies and highly selective anatrophic nephrotomy are described. The advantages and disadvantages of these methods are summarized and the results of treatment in 58 patients are presented.
