Gluteal-fold adipofascial perforator flap transposition for rectourethral fistula reconstruction

摘要

If a rectourinary fistula does not close spontaneously, it requires surgical closure. We present our experience of rectourethral fistula reconstruction using a gluteal-fold perforator flap, resulting in a successful outcome. The patient was a 64-year-old man with prostate cancer who underwent radical prostatectomy. However, he developed rectourinary fistula, which required surgical closure. A dissection was undertaken to divide the fistula tract, and the rectal and urethral defect were closed. A 12.0x3.0 cm gluteal-fold adipofascial perforator flap was harvested and placed in the space between the rectum and urethra. The viability of lap was favourable, without infection or necrosis. The patient could walk the next day, and was discharged 2 weeks later without fecaluria or liquid stool. We conclude that the gluteal-fold adipofascial perforator flap offers excellent functional advantages in rectourethral fistula reconstruction with minimal morbidity at the donor site.
