| Objective: To investigate the clinical significance ofthe R.E.N.A.L. nephrometry score in patients with kidney malignant tumor who wereunder went nephron-sparing nephrectomy.Methods: from December2012to February2014,59patients under wentnephron-sparing nephrectomy were collected retrospectively from our clinical database.Of which49underwent retroperitoneal laparoscopic partial nephrectomy and10underwent open partial nephrectomy according to clinical characteristics, imageexamination, complications. A R.E.N.A.L. nephrometry score was evaluated to eachrenal tumor according to CT and MRI imaging data. Operationtime, renal artery clamping time, change of the serum creatinine level, blood loss andoperation approaches (open vs. minimally invasive) were analysed with respect totheir R.E.N.A.L. score.RESULTS: The R.E.N.A.L. nephrometry score of renal mass correlatedsignificantly with our operation approaches (open vs. minimallyinvasive), renal artery blockage time, change of the serum creatininelevel and blood lossï¼›while it did not correlate significantly with perioperativecomplications or postoperative hospital stay.Conclusions: The nephrometry score objectively describe renal mass characteristics. Ithelps surgeons to choose surgical approach and may predict perioperative outcomes.However, further research is required to evaluate its clinical significance moreaccurately. |
