• Resumen

  • Background: The endoscopic treatment of complete ureteral transections has been reported. However, records on the use of metallic ureteral stents for this purpose are lacking. We present a case of complete ureteral transection successfully treated with ureteral realignment using an Allium ureteral stent.

    Case Presentation: A 70-year-old man underwent abdominoperineal amputation due to rectal cancer. Postoperatively, he was diagnosed with a complete right ureteral transection and subsequent urinary leakage. Pyelography revealed that the two ureteral ends of the injured area were not contiguous. A ureteral guidewire was passed through the injured area using a combined antegrade and retrograde approach. Given the severity of the injury, realignment with an Allium ureteral stent was attempted. Following successful placement, the urinary leak resolved, and the affected renal unit remained free of hydronephrosis. The short-term follow-up (2 weeks) does not allow assessment of long-term outcomes, which represents a major limitation of this report.

    Conclusions: To the best of our knowledge, this study is among the very few reported cases utilising an Allium stent for the endoscopic realignment of complete ureteral transection. We believe that this stent may be useful in the endoscopic resolution of complete ureteral transections because of its larger diameter and ability to isolate the affected area compared with other catheters such as the double-J stent.
