Abstract
Background:
The aim of this article is to present our experience of pedicled dorsal penile skin tube as neourethra after radical penectomy due to invasive primary male carcinoma of anterior urethra.
Methods:
This is an observational descriptive study including seven men with primary urethral carcinoma who underwent radical penectomy between 2018 and 2021. Instead of urinary derivation with suprapubic catheter, perineal urethrostomy, or bladder orthotopic/heterotopic reconstruction, patients underwent reconstruction of the anterior urethra with a pedicled dorsal penile skin tube. In brief, before corpora amputation and radical urethrectomy, the dorsal penile skin is preserved to reconstruct the neourethra. The distal end of the skin is anastomosed with the proximal urethral stump (usually membranous urethra) to assure continuity of the urinary tract, without jeopardising urinary continence. Finally, the flap is tubularized with two layers of watertight running sutures.
Results:
Median age was 50 (35–70) years. Histology revealed squamous cell carcinoma in all patients. Almost 100% of patients presented locally advanced (pT3–4, G3) disease and received perioperative chemotherapy (MVAC). The median follow-up was 10 (5–24) months. Median operative time was 230 min (190–315). There were not severe (Clavien–Dindo III–IV) perioperative complications. All patients were able to void in standing position through the reconstructed neourethra. No patients reported post-operative incontinence. Two patients died after 8 and 11 months from surgery.
Conclusion:
This new technique of using the dartos-based dorsal penile skin tube urethroplasty offers the possibility to void in standing position after radical penectomy with no need of urinary derivations.
Level of evidence:
Not applicable.
