Background/Objectives: Penile urethral stricture is a therapeutically challenging condition that significantly impacts quality of life and is often managed initially with urethral dilation or internal urethrotomy. However, both techniques are associated with high recurrence rates, limited long-term efficacy, and potential adverse effects, particularly in the penile urethra. Urethroplasty remains the gold standard but is invasive and not suitable for all patients. Optilume, a paclitaxel-coated balloon, combines mechanical dilation with localized drug delivery to reduce recurrence rates and the need for re-intervention. This study evaluated its effectiveness in patients with penile urethral strictures. Methods: A retrospective, multicenter study was conducted at two German clinics. Eight male patients (mean age 59) with symptomatic penile urethral strictures underwent Optilume treatment. Symptom severity was assessed using the International Prostate Symptom Score (IPSS) and quality of life (QoL) scores before and after treatment. The primary endpoint was symptom improvement, while the secondary endpoint was the need for reintervention. Patients were followed for a median of 16.5 months. Statistical analyses included Wilcoxon signed-rank and Mann–Whitney U tests. Results: The median IPSS improved from 25.5 to 5.0 and QoL scores from 4.5 to 1.0 after treatment (p < 0.01 for both). No patients required reintervention during follow-up. The subgroup analysis showed slightly better outcomes in patients without prior interventions, although differences were not statistically significant. The stricture length did not correlate with treatment response. Conclusions: Optilume significantly reduces urinary symptoms and improves QoL in penile urethral strictures, and the absence of re-interventions during follow-up underscores its durable mid-term success. It offers a minimally invasive alternative to urethroplasty, particularly for patients seeking symptom relief with a shorter recovery time and no hospital stay or general anesthesia. These preliminary findings suggest that Optilume may be a promising minimally invasive option for selected patients. Larger, controlled studies are warranted to validate these results and refine patient selection criteria.
