Anterior sagittal approach without splitting the rectal wall.

INTRODUCTION: The anterior sagittal transrectal approach (ASTRA) has already become popular to treat lesions in the proximal urethra such as trauma, duplicity and stenosis, prostatic utricle, urethral-vaginal fistulas and urogenital sinus anomalies. It provides much better exposure than the traditional perineal approach. Morbidity caused by this technique could be potentially decreased if the anterior sagittal access were to be made without sectioning the rectum. We report our initial experience using anterior approach without rectal sectioning for the treatment of three different types of pelvic disorders. PRESENTATION OF CASE: Anterior sagittal access without sectioning the rectal wall was carried out in three different clinical cases - a vaginoplasty in a female patient with congenital adrenal hyperplasia; to treat paradoxical urinary incontinence in a patient with proximal hypospadias (46XY karyotype) and another one with gonadal dysgenesis (46XO/XY karyotype). DISCUSSION: Several surgical techniques have been reported to repair congenital or acquired lesions in the posterior urethra with high morbidity and no guarantees of adequate and safe surgical exposition. ASTRA provides an excellent exposure, splitting only the anterior rectal wall. In this study, the anterior sagittal approach was applied without splitting the rectal wall to repair different posterior urethral anomalies, providing excellent exposure without compromising the fecal continence mechanism.
CONCLUSION: The anterior sagittal approach without splitting the rectum is a feasible procedure which provides excellent exposure to the posterior urethra in most cases and leads to less morbidity as it avoids the splitting and suturing of the rectum anterior wall.
