摘要

Purpose

This study aims to compare postoperative complication rates between zero fragment rate (ZFR) and stone free rate (SFR) patients after retrograde intrarenal surgery (RIRS), and to assess the relevance of stone volume versus maximum stone diameter (MSD) in postoperative evaluation.

Materials and methods

We conducted a retrospective, single-center study including 80 patients who underwent RIRS between December 2023 and December 2024 and had a postoperative CT scan within 3 months. Patients were classified as ZFR (< 1 mm fragments) or SFR (1–4 mm). The primary endpoint was the occurrence of ≥ 1 stone related event (SRE) within 6 months. Secondary endpoints included correlation between postoperative volume and MSD.

Results

SRE occurred in 18.4% of ZFR patients versus 40.5% in SFR patients (p = 0.047). No significant difference was observed in baseline stone characteristics, but BMI was higher in ZFR patients (p = 0.025). Postoperative volume correlated poorly with diameter (r = 0.30), supporting volume-based assessments.

Conclusion

Our findings suggest that ZFR status is associated with twice fewer SRE at 6 months and should be the preferred surgical goal when feasible. ZFR could be considered as the new gold standard for publications after RIRS. Volume-based assessment may offer greater accuracy than diameter alone and deserves further evaluation.
