Introduction: Literature suggests that the percutaneous punctures for percutaneous nephrolithotomy (PCNL) must be performed at the papilla of the renal calix and a puncture at the infundibulum or the direction of the pelvis is not advisable because of increased hemorrhagic risk. A prospective randomized study was conducted to investigate the safety in terms of blood loss of the infundibular approach for PCNL. Materials andmethods: Patients with renal stoneswith an accumulative size of at least 2 cmwere randomly assigned to one of twoparallel groups to undergo PCNLwith either papillary (Group 1) or infundibular (Group 2) renal access. The primary outcome measures were the reduction in hemoglobin on first postoperative day and the need for transfusion during the first postoperative month. Secondary endpoints included the operative and fluoroscopy time, number of accesses performed, overall complication rate, hospitalization time, and complications up to 3 months. Results: In total, 27 and 28 patients were enrolled in Groups 1 and 2, respectively. Patient age, body mass index, and stone size were similar among the groups (p = 0.672, 0.256, and 0.889, respectively). Reduction in hemoglobin and transfusion rate did not differ among Groups 1 and 2 (p = 0.916, p = 1.0, respectively). Operative time was higher in the case of Group 1 (p = 0.027). The overall complications rate was 7.4% for Group 1 and 7.14% for Group 2. Hospitalization time was not significantly different in the study groups (p = 0.724). Conclusions: The infundibular approach for PCNL to the posterior middle renal calices is not associated with higher blood loss or transfusion rate in comparison with the respective approach to the fornix of the papilla when the currently described technique is performed.
