Which of the following is NOT a common postoperative complication following urological surgery?

Epididymitis is indeed not a common postoperative complication following urological surgery. While it is an inflammatory condition of the epididymis, it is more often associated with infections or injuries rather than directly resulting from the surgical procedure itself. Common postoperative complications after urological surgeries typically involve physiological or anatomical alterations that directly arise from the surgical intervention.

Temporary incontinence, impotence, and infection are frequently observed postoperative issues. Temporary incontinence may occur due to the manipulation of nerves or tissues involved in urinary function during surgeries such as prostatectomies. Impotence can also arise, particularly following surgeries that affect the prostate or pelvic area, as it may involve alterations in nerve pathways or vascular supply. Infection is a well-known complication in any surgical procedure due to potential exposure during surgery, the introduction of catheters, or the presence of drainage systems.

Therefore, while all these conditions can relate to the surgical continuum and the surrounding anatomical regions, epididymitis is less likely to be a direct result of surgical intervention, making it an exception among the options presented.
