Arterio-Ureteral Fistula: Systematic Review of 445 Patients. | LitMetric

AI Article Synopsis

Article Abstract

Purpose: Arterio-ureteral fistula (AUF) is an uncommon diagnosis, but increasingly reported and potentially lethal. This systematic review comprehensively presents risk factors, pathophysiology, location and clinical presentation of AUF aiming to increase clinical awareness of this rare but life-threatening condition, and to put this entity into a contemporary perspective with modern diagnostic tools and treatment strategies.

Materials And Methods: This review was performed according to the PRISMA (Preferred Reporting Items for a Systematic Review and Meta-Analysis of Individual Participant Data) guidelines. A literature search in PubMed® and EMBASE™ was conducted. In addition, retrieved articles were cross-referenced. Data parameters included oncologic, vascular and urological history, diagnostics, treatment, and followup, and were collected using a standard template by 2 independent reviewers.

Results: A total of 245 articles with 445 patients and 470 AUFs were included. Most patients had chronic indwelling ureteral stents (80%) and history of pelvic oncology (70%). Hematuria was observed in 99% of the patients, of whom 76% presented with massive hematuria with or without previous episodes of (micro)hematuria. For diagnosis, angiography had a sensitivity of 62%. The most predominant location of AUF was at the common iliac artery ureteral crossing. AUF-specific mortality before 2000 vs after 2000 is 19% vs 7%, coinciding with increasing use of endovascular stents.

Conclusions: AUF should be considered in patients with a medical history of vascular surgery, pelvic oncologic surgery, irradiation and/or chronic indwelling ureteral stents presenting with intermittent (micro)hematuria. A multidisciplinary consultation is necessary for diagnosis and treatment. The most sensitive test is angiography and the preferred initial treatment is endovascular.
