We present the medium-term results of 33 patients treated with Urolume Plus urethral stent between August 1990 and June 1996 in 9 Belgian and Luxembourg centers. They all had previous treatments for bulbo-membranous urethral stricture, but without sustained benefit (dilatation, internal urethrotomy, or/and urethroplasty). The mean age of the stricture was 5.4 years (+/- 4). The stent was inserted easily during a short hospitalisation. Median time of follow-up is two years (6 months to 4 years). Maximum flow rate at last follow-up was 20.7 ml/sec (+/- 7), and 83.3% of the patients were satisfied with the stent. In 70% of the cases, the stent achieved its purpose of maintaining a good urethral lumen. In 5 patients (15.15%), stricture recurred inside the stent and in 2 patients (6.06%) a new stricture appeared on another site. Among these 7 patients, 5 were satisfactorily treated by endoluminal resection (4 cases) or dilatation (1 case). There were 2 real failures (= 6%): one patient who has refused any complementary endoscopic treatment and the other one who is still undergoing repeated urethral dilatations. Having respected the right indications for this device, we are satisfied of the results. It is a good alternative after failure of other treatments for bulbar-membranous stricture.
我们展示了1990年8月至1996年6月期间在比利时和卢森堡的9个中心接受Urolume Plus尿道支架治疗的33例患者的中期结果。他们此前均接受过球膜部尿道狭窄的治疗,但均未获得持续疗效(扩张、尿道内切开术或/和尿道成形术)。狭窄的平均病程为5.4年(±4年)。在短暂住院期间,支架易于插入。中位随访时间为两年(6个月至4年)。末次随访时的最大尿流率为20.7毫升/秒(±7),83.3%的患者对支架满意。在70%的病例中,支架达到了维持良好尿道腔的目的。5例患者(15.15%)在支架内出现狭窄复发,2例患者(6.06%)在其他部位出现新的狭窄。在这7例患者中,5例通过腔内切除术(4例)或扩张术(1例)得到了满意的治疗。有2例真正的失败病例(=6%):1例患者拒绝任何补充性内镜治疗,另1例患者仍在接受反复的尿道扩张术。在遵循该装置的正确适应证后,我们对结果感到满意。它是球膜部狭窄其他治疗失败后的一种良好替代方法。
