Résumé

Introduction: We evaluate the associations between 3 renal tumour scoring systems and their components with perioperative complications of partial nephrectomy.

Methods: A consecutive cohort of partial nephrectomy patients was analyzed. Patient characteristics were abstracted from medical records. PADUA scores (preoperative aspects and dimensions used for anatomic classification), RENAL (radius exophyic/endophytic nearness anterior/posterior location scoring) nephrometry scores, and Centrality index (C-index) were determined from preoperative axial images by 2 independent reviewers. Cases were evaluated for postoperative complications up to 30 days after surgery. Pre-specified complication definitions were used for 33 potential medical and surgical complications. Unadjusted and adjusted associations between overall scores, individual components, and complications were determined using log binomial regression.

Results: In total, 118 patients were included in the study. Of these, 36 (30.5%) surgical complications occurred in 27 (22.9%) patients. Fourteen (11.9%) were Clavien grade ≥3. Overall PADUA score was significantly associated with surgical and overall complications after adjusting for potential confounders. Among all components of the 3 scoring systems, only tumour diameter and exophytic/ endophytic nature of the tumour were significantly associated with complications after adjusting for the other components of the respective scoring system (p < 0.05).

Conclusions: Renal tumour scoring systems may help predict the risk of complications after partial nephrectomy. Further refinement of current systems is required. A first step would be to include only components that are significantly associated with complications.
