| Popis: | Bladder-outflow obstruction is a common age-related clinical entity due to a variety of benign and malignant diseases of the prostate. Surgical treatment is not suitable for high-risk elderly patients who seek minimally invasive management. We present a prostatic thermo-expandable metal stent for treating bladder-outflow obstruction. In this review, we include the design characteristics of this novel device, the performance assessment in comparison with alternative devices, the limitations, our personal clinical experience, as well as a long-term perspective. According to our experience among 127 patients (who underwent insertion of 192 stents) after 1, 2 and 3 years, 82, 61 and 47% of the original stents were functional without apparent complications, respectively. The mean single stent indwelling time was 1 year, with a maximum of 4 years. In 41% of patients, the stent needed to be removed and/or exchanged owing to stent encrustation (15%), migration (10%), penile pain (6%), bladder-outflow obstruction symptoms (5%), urinary incontinence ( |
