Acute pain after surgery typically subsides with tissue healing; however, some patients go on to develop persistent post-surgical pain (PPSP). It is estimated that 21-52% of people who had underwent thoracotomy, 21.5-47.3% of women who had breast surgery, and 4.7%-18% of people who had underwent abdominal surgery developed PPSP. The incidence of the condition varies substantially by the type of surgical procedure, which is also an important factor affecting the mechanism of PPSP. For example, while thoracic surgeries result in predominantly neuropathic pain due to intraoperative nerve injury, in hysterectomies and knee replacement surgeries the mechanisms of PPSP seem to be predominantly inflammatory. However, no data are currently available on the prevalence or potential mechanisms of PPSP after cystectomy.
