Objective: To present our experience with a novel technique that combines the York-Mason transsphincteric approach with dartos muscle flap interposition to treat rectourethral fistulas.

Methods: We extracted records from our prospectively kept database of 35 procedures conducted for treating rectourethral fistulas during 2002-2023; the York-Mason approach was combined with dartos muscle flap interposition in 5 cases, performed for treating rectourethral fistulas due to radical prostatectomy, all of which were referral cases.

Results: All 5 patients were successfully treated and followed up for a median of 70.0 months without recurrence. Before the fistula repair, all had a diverting stoma. In all cases, the first voiding cystourethrogram revealed a healed fistula. The posterior and the scrotal incisions healed uneventfully. All patients reported normal voiding and no urinary incontinence. To date, the stoma has closed in 3 patients, all of whom had intact fecal continence and no postoperative anal stenosis.

Conclusion: The transsphincteric modified York-Mason approach combined with dartos muscle flap interposition resulted in complete healing of rectourethral fistulas.

Iatrogenic urethral-rectal perforation represents a rare but severe complication arising from medical interventions, notably highlighted in the context of Foley catheter insertion. This case report outlines the presentation, diagnosis, management, and outcomes of a 71-year-old male patient who experienced iatrogenic rectal perforation during the routine insertion of a Foley catheter, against the backdrop of several predisposing factors, such as atrial fibrillation, valvular disease, benign prostatic hyperplasia, urethral stenosis, and colorectal cancer with liver metastasis. The inadvertent creation of a rectourethral fistula during the procedure led to an urgent multidisciplinary approach involving surgery and postoperative management, including fecal and urine diversion and antibiotic therapy.

Despite the widespread use of perirectal spacers to reduce radiation-induced rectal toxicity during prostate cancer treatment, postmarketing data reveal rare but significant complications. This case report details a severe complication of rectourethral fistula necessitating robotic pelvic exenteration with urinary and faecal diversion following perirectal spacer placement. Although SpaceOAR has been shown to reduce rectal radiation dose, the ensuing clinical benefit remains inconclusive in real-world data.
