To evaluate our longitudinal experience using visual internal urethrotomy (VIU) with intralesional mitomycin C (MMC) and short-term clean intermittent catheterization (CIC) for urethral strictures and bladder neck contractures (BNC) after failure of endoscopic management.
This case series involved review of our prospectively developed database of all men who underwent VIU with MMC and CIC in a standardized fashion for urethral stricture or BNC between 2010 and 2013 at our tertiary care medical center. Etiology was identified as radiation-induced stricture (RIS) or non-RIS and analyzed by stricture location. Cold knife incisions were made in a tri or quadrant fashion followed by intralesional injection of MMC and 1 month of once daily CIC.
All 37 patients previously underwent at least 1 intervention for urethral stricture or BNC before VIU with MMC and CIC. Mean stricture length was 2.0 cm (range, 1-6 cm; standard deviation, 1.0 cm). Over the median follow-up period of 23 months (range, 12-39 months), 75.7% of patients required no additional surgical intervention (RIS, 54.5%; non-RIS, 84.6%; P = .051). In those that did recur, median time to stricture recurrence was 8 months (range, 2-28 months). One patient with recurrence required urethroplasty.
VIU with MMC followed by short-term CIC provides a minimally invasive and widely available tool to manage complex recurrent urethral strictures (<3 cm) and BNC without significant morbidity. This approach may be most attractive for patients who are poor candidates for open surgery.
评估我们在经内镜治疗失败后,使用可视性尿道内切开术(VIU)联合病灶内注射丝裂霉素C(MMC)及短期间歇性清洁导尿(CIC)治疗尿道狭窄和膀胱颈挛缩(BNC)的长期经验。
本病例系列研究回顾了我们前瞻性建立的数据库,该数据库涵盖了2010年至2013年期间在我们三级医疗中心以标准化方式接受VIU联合MMC及CIC治疗尿道狭窄或BNC的所有男性患者。病因分为放射性狭窄(RIS)或非RIS,并按狭窄部位进行分析。采用三象限或四象限方式进行冷刀切开,随后病灶内注射MMC,并进行为期1个月的每日1次CIC。
所有37例患者在接受VIU联合MMC及CIC治疗前均至少接受过1次尿道狭窄或BNC的干预治疗。平均狭窄长度为2.0 cm(范围1 - 6 cm;标准差1.0 cm)。在中位随访期23个月(范围12 - 39个月)内,75.7%的患者无需额外的手术干预(RIS患者为54.5%;非RIS患者为84.6%;P = 0.051)。复发患者的狭窄复发中位时间为8个月(范围2 - 28个月)。1例复发患者需要进行尿道成形术。
VIU联合MMC并辅以短期CIC为治疗复杂复发性尿道狭窄(<3 cm)和BNC提供了一种微创且广泛可用的工具,且并发症发生率低。对于开放手术不适合的患者,这种方法可能最具吸引力。
