Male Urethroplasty
Male urethral reconstruction encompasses procedures used to restore luminal continuity and adequate caliber to the urethra following stricture, trauma, lichen sclerosus, failed prior surgery, or congenital anomaly. Techniques range from simple endoscopic dilation to highly complex multi-stage flap reconstructions using oral mucosa, penile skin, gracilis muscle, or bowel. The library spans >30 distinct techniques across 8 categories, evolving from the early staged approaches (Johanson 1953, Turner-Warwick 1960s) through the pedicled-flap era (Orandi 1968, Quartey 1983, McAninch 1993) to the BMG-dominant era (Barbagli 1996, Kulkarni 2009, Nikolavsky 2016) and an emerging minimally-invasive frontier (transmeatal, endoscopic, robotic, tissue-engineered). The History of Urethral Surgery traces these eponymous procedures.
Decision Framework — Choosing a Male Urethroplasty
The matrix below summarizes the primary decision points, aligned with EAU guidance on anatomy and tissue selection.[1] Before selecting a repair, define stricture site and length with retrograde urethrography; add voiding cystourethrography for a nearly obliterative stricture, stenosis or PFUI to show its proximal extent .[8] The AUA 2023 guideline recommends oral mucosa as the first-choice graft , advises against genital skin in lichen sclerosus , and advises offering perineal urethrostomy as a long-term alternative to urethroplasty for patients at high risk of reconstruction failure .[2] The same guideline treats buccal and lingual grafts as equivalent , advises against unsupported single-stage tubularized graft urethroplasty , hair-bearing skin , and allograft, xenograft or synthetic substitutes outside experimental protocols .[2] It distinguishes a fully supported tubularized fossa-navicularis graft from an unsupported replacement tube.[2] EAU 2026 adds a strong recommendation to offer perineal urethrostomy for complex anterior stricture disease and a strong recommendation against anastomotic urethroplasty for penile strictures longer than 1 cm because of postoperative chordee.[1][2]
For incisions and surgical approaches across the entire male-urethroplasty operative spectrum, including perineal skin incisions, the three penile-stricture exposure approaches, anterior urethrotomy approaches (ventral / dorsal Barbagli / dorsolateral / non-transecting), posterior approaches, graft-placement configurations, and one-stage versus staged repair, see Male Urethroplasty — Incisions & Approaches.
| Clinical Scenario | Reconstructive option | Alternative(s) | Avoid / limitations |
|---|---|---|---|
| Short nontraumatic bulbar stricture | Non-transecting repair or BMG | Vessel-sparing EPA in selected anatomy | Routine transection when a suitable preserving repair is feasible |
| Short traumatic bulbar obliteration | Transecting EPA when full-thickness scar requires excision | Individualized reconstruction for longer defects | Forcing a tensioned anastomosis |
| Long bulbar stricture (2–5 cm) | Dorsal onlay BMG (Barbagli or Kulkarni one-sided) or ventral onlay BMG (proximal bulbar), selected by expertise and intraoperative findings.[1][5] A GURS survey found that 66% favored dorsal and 34% ventral placement (134 of 350 invited members responded); this measures practice preference.[4] | Asopa dorsal inlay in selected anatomy | Routine transecting AAU when non-transecting graft repair is feasible (recurrence HR 4.8 versus non-transecting dorsal onlay in one retrospective bulbar dorsal-BMG cohort; mean stricture length 4.4 cm[3]); a short nearly obliterative segment may warrant non-transecting augmented repair (EAU weak recommendation[1]) |
| Penile stricture (non-LS) | Asopa dorsal inlay or Kulkarni dorsolateral onlay | Dorsal Orandi flap; staged BMG | Ventral onlay (sacculation risk) |
| Penile stricture (LS) | Oral-mucosal reconstruction; one-stage when tissue permits | Staged oral-mucosal repair for adverse tissue conditions | All genital skin grafts/flaps |
| Panurethral stricture | Kulkarni one-sided dorsolateral BMG | Preputial spiral graft (PSGU); combined BMG + flap; perineal urethrostomy | — |
| Uncomplicated primary meatal or fossa navicularis stricture | Meatotomy / meatoplasty for focal meatal disease | Dilation or meatotomy in selected primary cases[2] | Choose by extent and tissue quality |
| Recurrent meatal or fossa navicularis stricture | Transmeatal ventral inlay BMG (Nikolavsky) in suitable anatomy | Sliding-T dorsal inlay (Rourke); meatoplasty for selected focal disease | Repeated dilation or meatotomy as a definitive plan[2] |
| Long bulbar disease with a short critical segment | Graft augmentation with selective anastomotic repair | Double-face BMG or ntAAU, according to plate and scar | Treating all obliterations as the same lesion |
| Failed prior graft / poorly vascularized bed | For a suitable long bulbar redo, repeat oral-mucosal free-graft urethroplasty [1]; for a poorly vascularized bed with suitable non-LS genital skin[2], consider a pedicled flap (Orandi, McAninch, Quartey) ± dorsal BMG | Vanni / Zinman ventral BMG + gracilis (radiation / salvage) | Free graft alone in a poorly vascularized bed |
| Depleted oral mucosa | Penile skin graft when healthy non-LS skin is available ; consider a pedicled preputial flap for a poorly vascularized bed .[6] | Rectal mucosal graft (TEM / R-TAMIS) (see Enterourethroplasty); colonic mucosal graft if oral mucosa and penile skin are unavailable, unsuitable, or declined.[6] | Avoid genital skin graft in LS ; colonic graft harvest requires an abdominal procedure.[6] |
| Oral dyskeratosis (gutkha / betel nut) | Examine oral donor mucosa; use oral mucosa if suitable, or a preputial skin flap (dorsal onlay) when it is unsuitable and healthy non-LS prepuce is available.[2][7] | Penile skin graft when oral mucosa is unsuitable and healthy non-LS skin is available | Avoid harvesting diseased oral mucosa.[7] |
| PFUI (posterior) | Perineal anastomotic urethroplasty (see PFUI) | Transpubic abdominoperineal (if perineal insufficient) | Repeated endoscopic procedures |
| Older / comorbid; panurethral; patient preference | Definitive perineal urethrostomy | — | Complex reconstruction if patient declines |
