Just as important as surgical outcome are complications after surgery. Complications can not only affect the treatment outcome but also put a mental strain on both the patient and surgeon. However, every surgeon knows that even the perfect patient and flawless procedure can result in an unexpected complication. In this regard, prevention of any complication should be a priority with every operation. This book takes the baton from most textbooks that are usually limited to describing surgical steps and focus on the background behind possible complications and ways to prevent and manage them. Therefore, the reader is also provided with knowledge of preoperative patient risk factors that can aid in patient selection and consultation. In addition, the book includes nonurologic complications such as complication from anesthesia after urologic surgery and complications arising from medical therapies in everyday urologic practice. Furthermore, included topics stem from basics such as patient positioning to the most recent robotic surgery and this makes the book a requisite in every urologist's bookshelf from the training resident to the seasoned surgeon.
