Principles of anaesthesia in urological surgery.

Anaesthesia for urological surgery poses particular challenges for the anaesthetist related to the patient population and procedure type. The aim of this article is to cover the general principles of anaesthesia, with dedicated sections relevant to practising urological surgeons. This represents vast amounts of knowledge that cannot be covered in one article. We will focus upon preoperative preparation for surgery and anaesthesia, perioperative management including monitoring and analgesia, and postoperative management including fluid balance, critical care and recovery. Significant proportions of urological surgical patients have some degree of renal failure and this may be related to the surgery required. Anaesthetic care of patients with chronic renal impairment and transplant surgery will be covered in a future review.
