This device consists of a woven in a form of a tubular mesh, made up for the use in the urethra. We report the clinical and uroflujometric results in 10 patients with urethral stricture and 4 with obstructive prostatic hyperplasia. The study includes a 7 year period since October of 1993 up until June 2000. All patients were evaluated pre and post stent insertion with periodic follow ups to assess the prostatic symptoms score, quality of life assessment, peak urinary flow rate, mean flow rate and post-void residual urine volume. The results were the following: For the group with urethral stricture the I-PSS decreased from 26.8 to 5.4 points, the peak flow rate increased from 8.24 to 16.12 mL/sec and the post-void residual urine volume decreased from 42.7 to 31.6 mL. By 12-month follow-up most endoprostheses were 90% covered with urothelium, only one of these patients required stent extraction with no sphincter lesion. For the prosthatic hyperplasia group the I-PSS decreased from 20.2 to 8 points. The peak flow rate increased from 6.95 to 14.5 mL/sec and the post-void residual urine volume decreased from 49 to 18.3 mL. By 12-month follow-up two patients were 95% covered with epithelium, and the other two were 70%. There have not been significant problems related to infections, migration, incontinence or erectile disfunction. An 80% of patients have shown some irritative symptoms (urgency, frequency or dysuria) at least during the first month after stent insertion. These 7 year results suggest that Urolume urethral endoprostheses can be a long-term effective treatment alternative to these patients.
该装置由编织成管状网眼形式的材料构成,用于尿道。我们报告了10例尿道狭窄患者和4例前列腺增生梗阻患者的临床及尿流率测定结果。该研究涵盖了从1993年10月至2000年6月的7年时间。所有患者在支架置入前后均接受评估,并进行定期随访,以评估前列腺症状评分、生活质量评估、最大尿流率、平均尿流率和排尿后残余尿量。结果如下:对于尿道狭窄组,国际前列腺症状评分(I-PSS)从26.8分降至5.4分,最大尿流率从8.24毫升/秒增至16.12毫升/秒,排尿后残余尿量从42.7毫升降至31.6毫升。到12个月随访时,大多数内置假体90%被尿路上皮覆盖,这些患者中只有1例需要取出支架且无括约肌损伤。对于前列腺增生组,I-PSS从20.2分降至8分。最大尿流率从6.95毫升/秒增至14.5毫升/秒,排尿后残余尿量从49毫升降至18.3毫升。到12个月随访时,2例患者95%被上皮覆盖,另外2例为70%。未出现与感染、移位、尿失禁或勃起功能障碍相关的重大问题。80%的患者至少在支架置入后的第一个月出现了一些刺激性症状(尿急、尿频或尿痛)。这7年的结果表明,Urolume尿道内置假体对这些患者可能是一种长期有效的治疗选择。
