RESUMO
Results of treatment of 276 patients, suffering the lower renalis calyx (LRC) calculi, hav' ing size (1.14 ± 0.35) Ñm, were analyzed. Depending on acuteness of Ñnfundibulo pelvic angle (ÐPA) the examined persons were divided on groups with blunt (n=118) and acute (n=158) IPA; 8 аnatomic parameters of the LRC were in total determined. There was established, that еxtracorporal shockwave lithotripsy, in accordance to the cal' culated index of a LRC calculis elimination, is expedient to apply in a bigger ÐPA, lesser Ñnfundibulolumbar angle, lesser length of the LRC neck; transcutaneous nephrolithotripsy is effective not depending from a calculi dimensions, length of the LRC neck, value of ÐPA and infundibulolumbar angle.
