Background: Partial nephrectomy became more preferred option in the treatment of localized small renal tumours due to recent advances in imaging modalities and surgical techniques. Renal scoring systems are known to compliment urologist in aiding surgical decision process on extent of surgery in small localized renal tumours. There are few scoring systems described in the literature with their own limitations. Methods: This is a retrospective study of patients with localized renal cell tumours who underwent nephrectomy at Nizam Institute of Medical Sciences (NIMS), Hyderabad fromJanuary 2017 to January 2019. Patients with advanced renal cell cancer disease at presentation were excluded. Total RENAL nephrometry Score (RNS), its individual component scores and complexity category were calculated based on CT report. The study cases were categorized into Group A (Partial Nephrectomy) and as Group B (Radical Nephrectomy). Mean and standard deviation value of the RENAL nephrometry scores and its component scores were calculated for each group. Statistical signicance was calculated using unpaired T-test, using SPSS statistics 21.0 software. Results: The mean age for all patients included in this study is 52.1 years. Out of 80 patients, 32 patients had partial nephrectomy (Group A) and 48 patients had radical nephrectomy (Group B). Based on RENAL nephrometry score complexity, Group A and Group B were further categorized into low, intermediate and high complexity score categories. The total RENAL score, individual component scores and RENAL score complexity were found to be signicantly different between the two group in addition to the tumor size. No statistical signicance was found between the two groups for age and type of tumour on histopathology (benign or malignant). Conclusion: We conclude that preoperative RENAL nephrometry scoring is a useful aid to surgeons to classify the renal tumour complexity before deciding on effective surgical strategy for better patient outcomes |
