Abstract
Background: Although accounting for only 2.6% of adult malignancies, renal cell carcinoma (RCC) is the 6th leading cause of cancer deaths in the United States. Surgical resection still remains the cornerstone of therapy for patients with localized renal cell carcinoma. Partial nephrectomy is an established treatment for renal tumors smaller than 4 cm in diameter. The standard open approach to partial nephrectomies has changed in recent years to minimally invasive techniques. Patients can be treated with partial nephrectomy via laparoscopic approaches (with and without robotic assistance) with less postoperative pain and shorter hospital stay. objective: This work is a prospective cohort study which aims to compare minimally invasive nephrectomy versus open nephrectomy regarding intraoperative factors, postoperative factors (as postoperative pain, hospital stay and complications) and oncologic safety of the procedure. patients and methods: A prospective cohort study including 62 patients with renal masses treated with nephrectomy whether partial, total or radical. 26 cases were treated by minimally invasive techniques (8 robotic and 18 laparoscopic), while 36 cases were treated by open technique.The study was performed at National Cancer Institute, Cairo University. Both techniques were assessed regarding operative time, blood loss, postoperative pain, hospital stay and surgical margin. A pvalue less than or equal to 0.05 was considered statistically significant. All tests were two tailed
