摘要

目的:双 J(Double J,DJ)支架作为一种临时解决方案被广泛应用于输尿管狭窄的病例中,但它也有一定的局限性,例如需要频繁更换。另外,一种长效热膨胀支架(Memokath™ 051)已被用于缓解合并症患者的输尿管梗阻,据报道这种支架具有多种优点,如使用寿命长,无需频繁更换。此外,它还可用于某些尿道狭窄病例。我们的研究是该地区首次报告 Memokath 支架治疗输尿管和尿道狭窄的经验和结果:经当地国际注册研究委员会批准后,我们回顾性审查了 2013 年至 2021 年期间在输尿管插入 Memokath 051 支架和在尿道插入 Memokath 045 支架的 21 例患者的记录。收集了插入指征、留置时间和移除原因,并用 SPSS 进行了分析:21名患者接受了21枚Memokath支架,用于治疗11处输尿管狭窄和10处尿道狭窄。55%的输尿管狭窄为恶性,27.3%的良性输尿管狭窄为移植性输尿管。输尿管membokath支架的平均使用寿命为16.1个月。移植输尿管membokath支架的平均留置时间为24.3个月。共有 4 个输尿管支架移位,4 个支架堵塞,2 个支架按计划移除,1 个支架因发热性尿路感染(UTI)而移除。10 个尿道支架平均放置了 14 个月。3个支架按计划取出,狭窄得到缓解,2个支架因堵塞而取出,3个支架发生UTI,1个支架因疼痛而取出,1个支架在患者去世前仍在发挥作用:结论:我们的研究结果与其他已发表的研究结果相当,表明与 DJ 支架相比,输尿管 Memokath 支架是一种具有足够留置时间的更好选择,尤其是在移植输尿管中。此外,Memokath 支架还可用于无法进行手术重建的复发性尿道狭窄。

Thermoexpandable Memokath stent: Usage and efficacy in ureteral and urethral strictures in Saudi Arabia.

Objectives: Double J (DJ) stent is widely used in cases of ureteric strictures as a temporary solution; however, it has certain limitations, such as the need for frequent exchange. Alternatively, a long-lasting thermoexpandable stent (Memokath™ 051) has been used to relieve ureteral obstructions in comorbid patients with multiple reported advantages, such as longer durability which avoids the need of frequent exchanges. In addition, it can be used in certain cases of urethral strictures. Our study is the first in the region to report the experience and outcome of Memokath stent with ureteral and urethral strictures.

Materials and methods: After local IRB approval, we retrospectively reviewed records of 21 patients who underwent insertion of Memokath 051 stent in the ureter and Memokath 045 in the urethra between 2013 and 2021. Indications of insertion, indwelling duration, and causes of removal were collected and analyzed by SPSS.

Results: Twenty-one patients received 21 Memokath stents for 11 ureteral strictures and 10 urethral strictures. Fifty-five percent of ureteral strictures were malignant, and 27.3% of the benign ureteric strictures were transplant ureters. Ureteric memokath stents remained functioning for a mean of 16.1 months. Mean indwelling time for transplant ureteric memokath stents was 24.3 months. Total 4 ureteric stents had migrated, 4 stents blocked, and 2 stents were removed as planned and 1 stent removed due to febrile urinary tract infection (UTI). Ten urethral stents remained in place for mean of 14 months. Three stents were removed as planned with resolution of stricture, two were removed due to blockage, three stents had UTI, one was removed due to pain, and one stent remained functioning until the patient expired.

Conclusion: Our outcome is comparable to other published studies, suggesting that ureteric Memokath stent is a better option with adequate indwelling time, especially in transplant ureters, in comparison with DJ stents. In addition, Memokath stents can be used in selected recurrent urethral strictures where surgical reconstruction is not feasible.
