Here, we report on technical feasibility and short-term outcome of a new technique: Transurethral resection of pre-formed fibrotic tissue before the placement of a thermo-expandable urethral stent for distal urethral stricture. METHODS The clinical records of 11 consecutive patients with distal urethra stricture (9 bulbous, 3 penile) were retrospectively reviewed (April 2011 – February 2013). As a first step, all patients were treated with transurethral resection of fibrotic tissue using 13Fr pediatric resectoscope to the level of normal looking corpus spongiosum and, then thermo-expandable urethral stents (MemokathTM 044TW) were deployed according to the conventional protocol. Stents were removed in 6-12 months of initial placement and urethral patency was determined in terms of the ability of pass 17Fr cystoscopy and the normal range of uroflowmetry (maximum flow rate (Qmax) ¡Ã 15ml/sec). Also operational feasibility of new technique with focus on peri- and post-operative complication was accessed. RESULTS Mean age of patients and operation time were 58.9 (32-83) years and 84.5 (30-110) minutes respectively. Mean follow-up duration was 14.9 (7-30) months and during this period in 9 from 11 patients, urethral stents were removed. Mean post-op Qmax (18.7¡¾5.7ml/sec) was significantly higher than that of pre-op (10.5¡¾2.6ml/sec, p < 0.05). Post-op urethral dilatation was performed mean 1.2 times (1-5) in 5 patients but no patients needed open urethroplasty during follow-up period. There were no significant complications including severe urethral bleeding, incontinence, erectile dysfunction, and intractable pain. CONCLUSIONS Combined transurethral resection of fibrotic scar tissue and temporary urethral stenting is feasible, safe, and efficient technique for distal urethral stricture. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e739 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Cheol Yong Yoon More articles by this author Sang Woo Kim More articles by this author Jong Jin Park More articles by this author Ji Yun Chae More articles by this author Jong Wook Kim More articles by this author Jin Wook Kim More articles by this author Mi Mi Oh More articles by this author Hong Seok Park More articles by this author Du Geon Moon More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
