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

## TL;DR

A rare case of an anal fistula developed after a vasectomy and was complicated by infections in the scrotal and perineal areas.

## Contribution

This case presents a unique anatomical location of a post-vasectomy fistula not previously reported.

## Key findings

- The fistula occurred in an otherwise healthy individual with no prior risk factors.
- MRI failed to identify the fistula, requiring diagnosis under anesthesia in the operating room.
- The condition was successfully treated with anal fistulotomy.

## Abstract

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.
