Urethrotomy

Contributor(s): Stephen Baines, Lori Ludwig, Aidan B McAlinden, Dick White

Introduction

  • Creation of a temporary opening in the urethra.

Uses

Temporary relief of urethral obstruction

Advantages

  • The most common site of urethral obstruction is the penile urethra (narrowest segment), although rarely obstruction can occur in the perineal urethra.
  • Surgical exposure is therefore normally performed over the base of the os penis (low/penile site).
  • Urethra is superficial and limited surrounding cavernous tissue.
  • If complications occur a revision surgery can be performed more proximally.

Disadvantages

  • Perineal urethrotomy: increased risk of scarring, urine scald and hemorrhage.
    Avoid wherever possible.
