55 consecutive anatrophic nephrolithotomies on 53 patients performed between July, 1983 and June, 1990 were reviewed. The patients(36 male and 19female) ranged in age from 3to 72years. The operation time averaged 219.8 minutes with a range of
120-330
minutes, and the ischemic time ranged between 20 and 90 minutes, with a mean of 43.5 minutes. Postoperative complications developed in 18 patients, which were such as persistent urinary tract infection in 5cases(9.4%), atelectasis in 4(7.5%),
transient
urine leak in 2(3.8%), delayed bleeding in 2(3.8%) and urinary retention in 2(3.8%). Postoperative residual stones were identified in 15(27.3%), but in 8 of these 15 patients stones were delivered spontaneously and thus 48 of 55 cases(87.3%)
became
stone free. The recurrence of stone was noted in 2 out of 48 patients during the short followup period. Anatrophic nephrolithotomy seems to be an effective method compared to other procedure because of decreasing recurrence of stone of complete
stone
removal and reconstruction of abnormal collecting system.
