CPT® Code 53235

Excision of a urethral diverticulum in males, as described by CPT® Code 53235, refers to a surgical procedure aimed at removing a diverticulum, which is an abnormal pouch or sac that can form in the urethra. Male urethral diverticula are relatively uncommon and are typically located in the proximal region of the penile urethra or the distal part of the bulbous urethra. The procedure begins with the patient being properly prepped and draped to maintain a sterile environment. A catheter is inserted transurethrally to facilitate access and visualization during the surgery. An incision is made in the skin to expose the underlying corpus spongiosum, which is the erectile tissue surrounding the urethra. The surgeon then carefully dissects the diverticular sac away from the corpus spongiosum, ensuring that any surrounding attenuated tissue at the ostia, or opening of the diverticulum, is also removed. After the diverticulum is excised, the muscular and mucosal layers of the urethral defect are closed vertically over the catheter to restore the integrity of the urethra. In some cases, drains may be placed to prevent fluid accumulation. The corpus spongiosum is then sutured closed, followed by the closure of the skin incision. Finally, the urethral catheter is left in place to aid in urinary drainage during the initial recovery period.
