Transurethral balloon dilation (BD) is a minimally invasive treatment for urethral stricture disease (USD) performed primarily or as a recurrence salvage maneuver. With the introduction of drug-coated balloons, we sought to characterize patient outcomes using non-medicated balloons. A retrospective review identified patients who underwent BD from 2007 to 2021. Patient and stricture characteristics were collected. All dilations employed the 24Fr UroMax™ system. Clinical failure was defined by patient-reported lower urinary tract symptom recurrence or need for further stricture management. Ninety-one patients underwent BD with follow-up median (IQR) 12 (3–40) months. Most (75/91, 82%) had prior treatment for USD (endoscopic 50/91 (55%), 51/91 (56%) urethroplasty) before BD. Recurrence rates did not significantly differ between treatment-naïve and salvage patients (44% vs. 52% (p = 0.55)). Median (IQR) time to failure was 6 (3–13) months. The most common complications were urinary tract infection (8%) and post-operative urinary retention requiring catheterization (3%). Radiation history was noted in 33/91 (36%) with 45% recurrence. Patients without previous radiation had a similar recurrence rate of 52% (p = 0.88). Balloon dilation had minimal complications and overall, 50% recurrence rate, consistent regardless of stricture characteristics, radiation history, or prior treatments. These results represent an important clinical benchmark for comparing outcomes using drug-coated balloons.
