Anal Fistula That Developed After Bilateral Vasectomy Complicated by Scrotal and Perineal Infections.

We present a case of an anal fistula that developed after bilateral vasectomy complicated by scrotal and perineal infections. The anatomical location of this post-vasectomy fistula was unique, as previously reported vasocutaneous fistulas after vasectomy typically occur in the scrotum. Another unusual aspect of this case was that it developed in an otherwise healthy individual, without any predisposing risk factors such as prior genitourinary surgery, radiation, or voiding dysfunction. A repeat pelvic MRI did not identify this fistula, which was ultimately diagnosed through examination under anesthesia in the operating room and successfully treated with anal fistulotomy.
