Rectourethral fistulas have diverse causes and require tailored surgical strategies for closure. While diagnosis is classical, MRI offers a new approach, and endoscopic techniques show promise for treating these complex conditions.

Area of Science:

  • Urology
  • Surgical Gastroenterology

Background:

  • Rectourethral fistulas (RUFs) are increasingly studied, but literature lacks robust epidemiologic data.
  • Existing studies are often retrospective, clinical, or case-reports, highlighting a gap in understanding RUF incidence.
  • RUFs can stem from congenital or acquired causes, including inflammatory, neoplastic, and traumatic etiologies.

Purpose of the Study:

  • To review the diverse etiologies of rectourethral fistulas.
  • To discuss current diagnostic algorithms and emerging approaches like MRI of the male urethra.
  • To outline surgical management strategies, emphasizing the need for etiology-specific treatment.

Main Methods:

  • Literature review focusing on rectourethral fistula etiology, diagnosis, and treatment.
  • Analysis of diagnostic modalities, including classical methods and advanced MRI techniques.

  • Evaluation of surgical approaches, ranging from multi-stage procedures to novel endoscopic interventions.

    • Main Results:

    • A wide spectrum of causes for rectourethral fistulas exists, necessitating individualized surgical plans.
    • Magnetic Resonance Imaging (MRI) is a key diagnostic tool for the male urethra.
    • Most rectourethral fistulas require a three-stage surgical treatment, though some cases may resolve with diversion or one-stage procedures.

    Conclusions:

    • Recognizing the diverse etiologies of rectourethral fistulas is crucial for selecting appropriate surgical strategies.
    • While classical diagnostic methods are established, MRI enhances urethral evaluation.
    • Multi-stage surgical interventions remain the mainstay for rectourethral fistula closure, with endoscopic approaches offering future potential.
