Allium® bulbar urethral stent (BUS) for severe recurrent urethral stricture in a renal transplant recipient: a minimally invasive graft-preserving solution

Urethral strictures in kidney transplant recipients seriously jeopardize graft function, causing urinary stasis and infections. We report a 54-year-old male kidney transplant recipient with recurrent bulbar urethral stricture, multiple failed urethrotomies, and long-term urinary devices dependency. Recurrent UTIs and graft dysfunction prompted Allium® bulbar stent placement. At 12 months, uroflowmetry improved (Qmax from 7.9 to 9 mL/s), post-void residual dropped (100 mL to 30 mL), and IPSS decreased (25 to 9). Graft function improved (creatinine 3 mg/dL). No hospitalizations occurred. This case suggests Allium® bulbar urethral stent may offer a safe, minimally invasive alternative in high-risk kidney transplant recipients.
