Abstract
LAPAROSCOPIC surgery is a relatively noninvasive therapy. The efficacy of urological laparoscopic procedures such as pelvic lymphadenectomy, simple nephrectomy, and adrenalectomy has been confirmed.1,2 However, these procedures require a pneumoperitoneum, which may cause cardiovascular and respiratory complications.3,4 Laparoscopic procedures also affect endocrine and metabolic functions, such as increases in the serum cortisol, prolactin, and glucose concentrations after cessation of the pneumoperitoneum.5
