Aim: To compare outcomes (stone-free rates, complications) of percutaneous nephrolithotomy (PCNL) in patients with kidney malformations and normal subjects having similar stone characteristics(surface area, configuration). Materials and Methods: Data of 170 patients who underwent PCNL were analyzed. Stone burden was 100-1564 mm2, stone configuration was pure pelvic, pure caliceal or complex (pelvic + caliceal) in Group 1 with renal anomalies (n = 18, 19 renal units, 20 sessions). Patients with similar stone characteristics without any renal anomaly comprised Group 2 (n = 152, 158 renal units, 161 sessions). Groups were compared regarding therapy success, outcomes, and complications. Stones 0.05). Although no significant differences were detected regarding pure caliceal and complex stones concerning above parameters between the 2 groups, lower stone-free and higher residual stone rates were detected in Group 1 having pure pelvic stones compared to normal subjects (P = 0.028). Conclusions: PCNL is a safe and effective procedure in patients with kidney malformations. Patients with anomalous kidneys bearing pure pelvic stones might have lower stone-free and higher residual stone rates compared to normal subjects after PCNL in this preliminary study.
