Papillary vs non-papillary access during percutaneous nephrolithotomy: Retrospective, match-paired case-control study

Abstract

The mean operative time was similar in between two groups. The mean hematocrit decreases not differ between the two groups (p = 0.56). In papillary group, only 2 patients (3.2%) required transfusion and only one patient (1.4%) in the non-papillary group had a transfusion with no statistically significant difference (p = 0.43). The overall complication rates were 7.1% in the papillary group and 7.2% in the non-papillary group (p = 0.89). Postoperative mean creatinine level was similar between the two groups. Conclusions: In this study, we found that non-papillary access is a feasible option for PCNL in the terms of stone-free status and complication rates.
