Abstract OBJECTIVES: To assess the efficacy of superior pole access for complex lower pole calyceal calculi. PATIENTS AND METHODS: In all, 102 patients with complex inferior calyceal calculi were included in a prospective unrandomized study. Complex inferior calyceal calculi were defined as multiple calculi in two or more inferior calyces of the lower polar group, with each calyx draining through a separate infundibulum and at an acute angle to each other. In 33 patients (32\%; group 1) an inferior calyceal puncture was made and in 69 (68\%; group 2) access was obtained through a superior calyceal puncture. The stone-free rates, decrease in haemoglobin, operative duration, requirement for additional tracts and second procedures in the two groups were compared. RESULTS: Stone clearance rates and blood loss values were better in group 2, although they were not significantly different. The mean operative duration, number of tracts required and the re-look procedure rate was significantly less in group 2. Two patients (3\%) in group 2 had hydrothorax related to supracostal puncture and required chest tube insertion. CONCLUSIONS: Superior calyceal puncture (supracostal or infracostal) affords optimum access to complex inferior calyceal stones, providing faster and better clearance with a single puncture, and less requirement for second-look procedures.
