Core-Through Urethrotomy
Core-through urethrotomy is an endoscopic technique used when a guidewire cannot be passed across a complete or near-complete urethral obliteration, typically after pelvic fracture urethral injury or failed prior repair. Using a rigid urethroscope from below and a flexible cystoscope from above (through the suprapubic tract), a core of scar tissue is excised to create a channel across the obliteration under direct binocular vision. While useful as a bridging procedure, definitive reconstruction with open urethroplasty is usually required.
