SUBSTANTIATION OF THE METHOD OF TREATMENT CHOICE FOR PATIENTS, SUFFERING CALCULI OF THE LOWER CALICES RENALES.

Results of treatment of 276 patients, suffering the lower renalis calyx (LRC) calculi, hav' ing size (1.14 ± 0.35) сm, were analyzed. Depending on acuteness of іnfundibulo— pelvic angle (ІPA) 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 shock—wave lithotripsy, in accordance to the cal' culated index of a LRC calculis elimination, is expedient to apply in a bigger ІPA, lesser іnfundibulo—lumbar angle, lesser length of the LRC neck; transcutaneous nephrolithotripsy is effective not depending from a calculi dimensions, length of the LRC neck, value of ІPA and infundibulo—lumbar angle.
