Abstract

UroLume®, or urethral endoprosthesis, was conceived as an easy placement device for patients with recurrent bulbar urethral stricture. With the passage of time, it was shown to cause more complications than benefits and its use was discontinued. However, it created a group of patients with complex urethral stricture that required multiple surgical treatments with unsatisfactory results. The widespread use at the end of the 1990s of buccal mucosa grafts for the treatment of urethral stricture began a new stage in the search for a definitive treatment for this type of patient.

The aim of our article was to present a surgical technique for the treatment of UroLume®-associated bulbar urethral stricture that has not been described in the literature.

A 71-year-old man presented with bulbar urethral stricture secondary to transurethral resection of the prostate who, 8 years ago, had UroLume® placement. He presented with another urethral stricture and was treated with numerous urethral dilations. Through the perineal approach, the endoprosthesis was completely removed, and based on the local tissue characteristics, a dorsal inlay and ventral onlay double buccal mucosa graft was placed with successful results at the 6th month of follow-up.

UroLume®,或尿道内假体,被认为是一种易于放置的装置,用于复发性球尿道狭窄的患者。随着时间的推移,它引起的并发症多于益处,因此停止使用。然而,它产生了一组复杂尿道狭窄的患者,需要多次手术治疗,结果不尽如人意。20世纪90年代末,颊粘膜移植广泛应用于尿道狭窄的治疗,为寻找这类患者的明确治疗方法开启了一个新的阶段。我们这篇文章的目的是介绍一种外科技术来治疗文献中未描述的与UroLume®相关的球尿道狭窄。1例71岁男性,8年前行尿道前列腺切除术后继发于球尿道狭窄。他再次出现尿道狭窄,并进行了多次尿道扩张治疗。经会阴入路完全取出假体,并根据局部组织特点,于随访6个月时行背侧嵌体、腹侧嵌体双颊粘膜移植物,结果成功。
