Surgery is the treatment of choice for clear cell renal carcinoma not responding to chemotherapy, radiotherapy, or immunotherapy. The surgical procedure used has evolved over time in the past 40 years, mainly because of the development and widespread use of diagnostic procedures such as ultrasonography and CT. As a direct consequence, parenchymal-sparing surgery was no longer only used for patients with solitary kidneys and its indication started to be extended to patients with tumors up to 4 cm in diameter, in whom it has been shown to be a safe and effective alternative to radical nephrectomy. The other important milestone in development of renal cancer surgery undoubtedly was the revolution started in the 90s with advent of laparoscopic renal surgery, which has become established over the past 20 years approximately. Laparoscopic surgery initially raised concern about oncological safety, but clinical series with sufficiently long follow-up times and large sample sizes are now available to consider the laparoscopic approach as a reliable procedure. Technological development has caused the laparoscopic technique to be no longer seen as a procedure for the future, but rather as an absolutely current technique which should be implemented in most urology departments. Implementation of any new procedure usually involves a number of complications which we should be prepared to assume, while making every effort to try and prevent them. It is therefore essential to develop, and to implement using common sense, a training program on the procedure. Selection of patients and conditions to be treated is a crucial part of such a program. |
