PURPOSE: Surgical access to the posterior urethra is often difficult and several surgical solutions have been proposed. We suggest an anterior sagittal transanorectal approach based on splitting the anterior rectal wall only. This alternative technique provides excellent exposure to the retrourethral region, permitting simple and safe surgery.
MATERIALS AND METHODS: Between 1994 and 1996 we performed surgery via the anterior sagittal transanorectal approach in 8 patients with a mean age of 9.06 years. Patients included 1 girl with a posttraumatic urethrovaginal fistula, 3 with intersex disorders (2 with mixed gonadal dysgenesis raised as boys and 1 with male dysgenetic pseudohermaphroditism with an enlarged urtricle) and 4 boys (1 with penile agenesis raised as girl, 2 with urethral duplication and 1 with prostatic rhabdomyosarcoma). The patient was placed in a knee-chest position. A midline sagittal incision was made through the anterior anorectal wall only and deepened through the perineal body to expose the posterior urethra and retrovesical space. After the pathological condition was corrected the anterior rectal wall and perineal body were reconstructed. The operation was completed with protective colostomy. In our final patient with prostatic rhabdomyosarcoma the anterior sagittal transanorectal approach was used without colostomy. Anorectal manometry was done 6 months postoperatively.
RESULTS: All patients were completely continent of stool and urine. Convalescence was unremarkable in all cases. Postoperative manometry in 7 patients revealed no differences from preoperative measurements.
CONCLUSIONS: This procedure should be considered a useful alternative to other techniques for various congenital and acquired pelvic disorders.
