Nephrometry scoring system selects candidates for radical nephrectomy versus nephron-sparing surgery for treatment of renal masses and predicts surgical and oncological outcome

Purpose: The study was designed to ensure the sensitivity of preoperative planning by applying radius, endophytic/exophytic, nearness to collecting system, anterior/posterior, and location to poles (RENAL) nephrometry scoring system on computed tomography films of patients having organ-confined solid and cystic renal tumors and to assess its correlation with the surgical technique by applying RENAL on the specimen intraoperative. Materials and Methods: Eighty-five patients with organ-confined solid and cystic renal masses underwent RENAL nephrometry system which was correlated with the surgical technique either radical or nephron-sparing surgery or the surgical and oncological outcome. Results: RENAL nephrometry scoring system shows high sensitivity with the type and outcome of surgery of resection of the renal tumors. Conclusion: RENAL nephrometry score system is an objective method to help in the decision of surgical approach to resect organ-confined solid and cystic renal tumors.
