Gynecological surgery is associated with general risks that also occur in general surgery, but specific lesions are frequently encountered. For example, due to the fact that the genital organs are closely related to the organs of the urinary tract, they can easily be injured. These injuries primarily include lesions of the urinary bladder and ureters, but intestinal and nerve damage can also occur. Regarding drugs, dose- and time-dependent effects are controversial. These effects include thromboembolic complications, myocardial infarction, cerebrovascular accidents and even the carcinogenic risk of development of an endometrium or breast cancer.
