Total corpora mobilization for penile reconstruction

ABSTRACT Purpose: Total corpora mobilization (TCM) is a novel technique that is used for penile reconstruction in cases of micropenis and penile amputation. Its principle is based on Kelly's procedure for bladder exstrophy (1). In contrast to the Kelly procedure, TCM is performed entirely through the perineum with the patient in the lithotomy position. Materials and Methods: TCM was performed on three patients. The first was a boy who suffered trauma from a dog bite at an age of eight months. At 23 years old he underwent TCM. The second patient had genital self-amputation induced by psychiatric disorder. After treatment, at 27 years old, he desired surgery for penile reconstruction. The third patient had partial androgen insensitivity syndrome (PAIS) with a micropenis and at 23 years old had TCM procedure. The patients were placed in the lithotomy position with a perineal incision in the midline. A subperiosteal incision was made and the corpora cavernosa were detached from the pubic arch and the ischial rami. The periosteum and the neurovascular bundles were preserved. Subsequently the corpora cavernosa was mobilized upward and the periosteum that was left attached to them was sutured to the pubis. Results: At twenty-four, nine, and six months, respectively, in the follow-up process, all patients expressed satisfaction with the final cosmetic appearance, penile length, and erectile function. Conclusion: TCM may prove to be an alternative for patients with a functional disturbance because of small penile length, though a higher number of cases and a more extended follow-up are needed to draw a more definitive conclusion.

A new double graft technique in urethroplasty for complex urethral stenosis: preliminary findings

ABSTRACT The management of complex urethral stenosis may involve different surgical techniques. As retraction of the graft may account for surgical failure, this risk increases in patients with more extensive stenosis requiring a graft of greater diameter. Although double grafts have already been used to maximize success in these cases, we propose a modified technique for urethroplasty with longitudinal urethral incision. The hypothesis was that this technique would increase the lumen by using only a urethral incision on the dorsal surface. Two patients presenting with recurrent urethral stenosis underwent urethroplasty using a double graft of oral mucosa that preserves the integrity of the spongy tissue and allows ventral inlay graft fixation using a midline relaxing incision in the portion of the urethra with stenosis. In both cases, the urethrocystoscopy and uroflowmetry performed after surgery showed a pervious and complacent urethra. After four and six months of follow-up, the postoperative outcomes were satisfactory for both patients. Further studies involving larger numbers of patients and long-term follow-up are required to evaluate the effectiveness of this method.
