Combining Transurethral Resection of Fibrous Tissue and Temporary Urethral Stent Insertion Is an Optimal Strategy for Minimally Invasive Treatment of Recurrent and Long Urethral Strictures
- The Allium BUS stent demonstrated a significantly higher urethral patency rate (81 %) at 1 year after removal than Memokath stent (81.0 % vs. 40.0 %, log-rank test p = 0.012).
- In cases where transurethral resection (TUR) was required due to severe fibrotic scarring, Allium BUS showed a 90.9 % success rate
- 36 patients
- Follow-up time: 1 year post removal

Bulbar Urethral Stents for Bulbar Urethral Strictures: Long-Term Follow-Up after Stent Removal
- 168 patients with recurrent bulbar stricture after internal urethrotomy
- Median range follow-up – 71 months
- No adverse events related to the stent or the procedure recorded
- No post-procedure complication observed
- Migration – 16 cases (9.5 %)
Important! Clinical success strongly depends on the indwelling time and the number of DVIU (direct visual internal urethrotomy) previously provided (clinical success is based on the stricture resolution). Clinical success is defined as a stricture resolution for the long-term follow-up after stent removal.

Novel Treatment Strategy for Management of Traumatic Bulbar Urethral Rupture Using Temporary Urethral Stent after Primary Realignment
- Success rate (maintaining urethral patency after trauma): 86.7 %
- 15 patients
- Follow-up time: 1 year
BUS Study (2016)
Allium™ Bulbar Urethral Stent: An Updated Long-Term Multi-Center Study with a New Treatment Modality for Bulbar Urethral Stricture
- 64 patients
- Up to 18 month indwelling time
- Only 9 % migration rate
- The overall success rate was achieved in 48 of 64 patients (75 %)
BUS Study (2012)
Management of Recurrent Bulbar Urethral Stricture – A 54 Patients Study with Allium Bulbar Urethral Stent
- 54 patients
- Only 4 % migration rate
- All patients reported good urinary flow after stent placement
- The unique characteristics of the stent make it an excellent solution for the treatment of bulbar strictures
BUS Study Summary (2007)
Recanalization of Urethral Strictures with Allium Stents (Dr. Marcovic)
- Success Rate: Permanent recanalization without voiding problems was observed in 85% of cases.
- Patients: 40 men
- Follow-up: 12-14 months
- Flow Rate Outcome: Improved urinary stream noted in majority.
- Migration Rate: 5%
- Encrustation Rate: not reported
- Conclusion: First regional experience using Allium stents showed strong efficacy and tolerance.
BUS Study Summary (2007)
Management of Recurrent Urethral Strictures
- Success Rate: 55% (18 of 33 patients). All 14 stent placements lasting at least 4 months resulted in long-term resolution after a mean follow-up period of 3.6 years.
- Patients: 33
- Follow-up: 18 months
- Flow Rate Outcome: all successful cases showed improved voiding.
- Encrustation Rate: not reported
- Conclusion: placement of a covered retrievable stent for a minimum of 4 months is effective in inducing long-term resolution of refractory urethral strictures.
- Conclusion: First regional experience using Allium stents showed strong efficacy and tolerance.
