Long-term results of permanent memotherm urethral stent in the treatment of recurrent bulbar urethral strictures

Abstract

Purpose: To evaluate the long term outcomes of permanent Memotherm urethral stent in the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty patients who underwent permanent Memotherm urethral stent implantation due to recurrent bulbar urethral stricture following previous unsuccessful surgical procedure from 1996 to 2002 were included in the study. Long--term outcomes of the patients were evaluated. Results: The overall success rate was 87.5% at the end of the tenth year. There was discomfort in implantation area in eight patients about 1 month following the procedure. These patients were treated with alpha-blocker and anti-inflammatory drugs. Stone formation was observed at the urethral stent implantation area in two patients. Post-void dripping has been observed in 15 patients up to the postoperative 3rd month. Stress urinary incontinence was observed in a patient with a 1-year follow-up. Partial stent migration was observed in two patients. None of the patients experienced pain during erection. Conclusion: Memotherm urethral stent is a minimal invasive surgical procedure which can be safely and effectively used in patients with recurrent urethral stricture.

The long-term results of temporary urethral stent placement for the treatment of recurrent bulbar urethral stricture disease

“…migration, discomfort, incontinence, infection and encrustation. Indeed, Atesci et al ( 8 ) reported high complication rate of permanent Memotherm ® urethral stent in recurrent bulbar urethral strictures (discomfort in implantation area: 40%, partial stent migration: 10%, stone formation in implantation area: 10% and dripping after micturition: 75%). They also found that the overall success rate of permanent urethral stents was 87.5% at the end of the tenth year.…”

Management of Recurrent Urethral Strictures: A Therapeutic Challenge

“…Various management modalities of urethral stricture disease, such as internal urethrotomy, intermittent urethral dilatations, and open urethroplasties, have been well described in the literature [2,3,7]. However, clear curative roles of these interventions are still underway with unimpressive rates of success.…”

“…Frequent recurrence after initial treatment is common [2]. Urethral stent implantation has been categorized as a minimally invasive technique that can be safely and effectively used as a primary surgical procedure to treat recurrent urethral stricture [3]. According to the American Journal of Roentgenology, temporary stent placement has been considered the treatment of choice in cases of recurrent urethral strictures.…”

Algorithm for choosing the method of surgical treatment for urethral strictures in males

“…Бужирование уретры, как изолированное, так и в сочетании с другими процедурами и в качестве метода послеоперационного предотвращения рецидивов, используется до сих пор [1][2][3]. Систематический обзор Jackson M.J. et al (2014) [2] включал данные наблюдения за 776 пациен-тами. Было отмечено снижение числа рецидивов у пациентов, которым выполняли бужирование уретры в сравнении с пациентами, которым не выполняли (ОР 0.70, 95% ДИ 0,48-1,00).…”

“…Установка уретрального стента, по данным Atesci et al (2014), является высокорезультативным методом с эффективностью до 87,5% с периодом наблюдения до 12 лет и сопровождается низкой частотой осложнений [5].…”
