Background: The
aim of this study was to assess the long-term clinical efficacy of temporary, Allium
round posterior stent (RPS) which was used for the treatment of recurrent
bladder neck contracture (BNC).
Methods: Records
of 44 patients with recurrent BNC who underwent Allium RPS placement after
bladder neck incision, between 2009 and 2021, were analyzed. After stent
removal, the the success criteria for Allium RPS treatment were defined as: no
evidence of stricture on urethrogram or endoscopy; more than 12 ml/sec of
urinary peak flow; and no recurrent urinary tract infections. Based on clinical
success, patients were divided into two groups and compared. Clinical success
was also evaluatedwith particular regard to stent indwelling time and
contracture etiology.
Results: All
patients had more than one bladder neck incision stent placement before. The
mean ± standard deviation age, stricture length, and indwelling time were
66.1±9 years, 2.2±1.3 cm, 8.1±2 months, respectively. Median (range) follow-up
was 62 (7-75) months. The etiologies of BNC in this cohort were 59.1%
retropubic radical prostatectomy; and 41% transurethral resection of prostate.
Overall clinical success was achieved in 68.1% and the success rates did not
differ by etiology. The success rates were 61.5% and 77.7% (P=0,209) for
retropubic radical prostatectomy and transurethral resection of prostate,
respectively. Longer indwelling time (8-14 vs 3-7, months) was significantly
associated with clinical success (80% vs 52%, P<0.05)
Conclusion: Based on our results and considering other treatment alternatives RPS Allium is safe, easy and useful for the treatment of recurrent BNC.
