Temporary double-J (DJ) stents, various metallic stent designs, or definitive corrective surgery can be the options management for ureteric stricture. As an alternative from DJ stents, Memokath-051<sup>TM</sup> (MMK-051<sup>TM</sup>) can be inserted in strictured ureters post radiotherapy for advanced prostate cancer patients. We present a case of an advanced prostate cancer which bilateral DJ Stents placed within MMK-051<sup>TM</sup>. A 76-year-old man with underlying hormone sensitive advanced prostate cancer completed radiotherapy. Post radiotherapy he developed bilateral ureteric strictures  and bilateral DJ stents  inserted.  He had to underwent multiple change of stents due to blockage. Patient had MMK-051<sup>TM</sup> inserted, however complicated with blockage due to encrustation. Improvisation method done by putting the bilateral DJ stents within the MMK-051<sup>TM</sup>. Patient had no more blockage of MMK-051<sup>TM</sup> after the placement of DJ stents within it. However, patient succumbed to death a year after the last procedure. Our case report highlighted encrustation of metallic ureteric stents and a novel approach to overcome this problem. Introduction  of additional DJ stents  not only reduced the incidence of MMK-051<sup>TM</sup> blockage but also improved the quality of life of the patient.</p></abstract><trans-abstract xml:lang="ru"><p>Причинами сужения мочеточника  могут быть как злокачественные новообразования, так и доброкачественные процессы. Для лечения стриктуры мочеточника применяют временные двойные J-образные стенты, металлические стенты различных дизайнов, реконструктивные операции. В качестве альтернативы двойным J-образным стентам после лучевой терапии у пациентов с распространенным раком предстательной железы при сужении мочеточника устанавливают стент Memokath-051<sup>TM</sup> (MMK-051<sup>TM</sup>). Мы представляем клинический случай распространенного рака предстательной железы, при котором двусторонние двойные J-образные стенты были установлены внутри стента MMK-051<sup>TM</sup>.</p><p>Мужчине 76 лет с распространенным гормоночувствительным раком предстательной железы проведен курс лучевой терапии, после которого развились двусторонние стриктуры мочеточника. Пациенту были установлены двусторонние двойные J-образные стенты. Он перенес многочисленные замены стентов по причине блокады. Пациенту был установлен стент MMK-051<sup>TM</sup>, однако у него развилось осложнение в форме блокады в результате инкрустации. В стент  MMK-051<sup>TM</sup> были установлены двойные J-образные стенты, после чего пациент перестал испытывать блокаду. Однако пациент скончался от рака предстательной железы через год после операции. В данном описании  клинического случая мы подчеркиваем важность инкрустации металлических мочеточниковых стентов и предлагаем подход к решению этой проблемы. Установка дополнительных двойных J-образных стентов не только снизила частоту блокады стента MMK-051<sup>TM</sup>, но и улучшила качество жизни пациента.</p></trans-abstract><kwd-group xml:lang="en"><kwd>stent</kwd><kwd>prostate cancer</kwd><kwd>ureteric</kwd><kwd>stricture</kwd><kwd>metallic stent</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>стент</kwd><kwd>рак предстательной железы</kwd><kwd>мочеточник</kwd><kwd>стриктура</kwd><kwd>металлический стент</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The case report was presented for Electronic Poster (E-Poster) in 31st Malaysian Urological Conference 2022.</funding-statement><funding-statement xml:lang="ru">Данное описание клинического случая было представлено в формате электронного постера (E-Poster) на 31-й Малазийской урологической конференции 2022 г.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
