The aim of this article is to generally describe the roles of main surgical modalities in treatment of renal tumors, especially in the CT1a category in clinical practice. Surgical modalities include the following: laparoscopic or open resection (LR, OR) and laparoscopic or open nephrectomy (LN, ON). Representation of these methods has been changing over years due to improved operative skills and equipment and due to a shift of tumors to the lower T categories. The sources of data were surgeries performed for renal tumors at the institution of the main author during the period 2002 to III/2016, reaching a total of 2204 cases (546 ONs, 647 LNs, 668 ORs and 343 LRs). Patients indicated for percutaneous ablative therapy or active surveillance were not included. During the whole period, the proportions of methods were: ONs 24.8%, LNs 29.4%, ORs 30.3%, LRs 15.6%. But during the years 2014 - III/2016, these changed to 12.6%:26.3%:31.6%:29.4% (in cT1a 1.7%:8.3%:37.8%:52.2%). Category cT1a constitutes in the years 2007 - III/2016 41.3%, in 2014 - III/2016 50.9%. Resections and minimally invasive approaches are being performed more frequently and are the preferred methods in surgical treatment of kidney tumors. Resection is now indicated in about 60% of cases (open laparoscopic resection are used nearly equally with a slight tendency for laparascopic predomination). In the cT1a category (amounting to approximately 50% of all surgically treated tumors), resection is possible in about 85-90% of cases.
