We present a novel endoscopic treatment approach to managing a spontaneously knotted urinary catheter around a ureteric stent.\n <\/jats:p>\n \n Subject:<\/jats:bold>\n A 79\u2010year\u2010old man presented to the Emergency department with confusion and acute renal failure. His background was significant for metastatic castrate\u2010resistant prostate cancer. His associated obstructive uropathy was managed with a long\u2010term right 7\u2010Fr R\u00fcsch ureteric stent, last changed 1 month prior and a long\u2010term 18\u2010Fr indwelling catheter. A CT intravenous pyelogram clearly demonstrated his indwelling catheter knotted around and through the distal intravesical portion of an appropriately positioned right ureteric stent.\n <\/jats:p>\n \n Results:<\/jats:bold>\n Following decompression of the left kidney via percutaneous nephrostomy, attempts were made to remove the urinary catheter under fluoroscopy with a variety of wires and introducers. The patient then underwent a general anesthesia, and the knot was successfully removed piecemeal with a Mauermayer stone crusher via 25\u2010Fr access sheath.\n <\/jats:p>\n \n Conclusion:<\/jats:bold>\n Endoscopic techniques such as the use of a stone crusher may be beneficial for the removal of difficult and complex catheter knots as demonstrated in this case. Catheter knotting should always be considered if the functioning or attempted removal of the catheter is abnormal and timely referral to a urologist is made.\n <\/jats:p>","DOI":"10.1155\/criu\/5559138","type":"journal-article","created":{"date-parts":[[2025,7,10]],"date-time":"2025-07-10T11:34:08Z","timestamp":1752147248000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Knotting of a Urinary Catheter and Ureteric Stent: A Unique Complication and Management Solution"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0395-6647","authenticated-orcid":false,"given":"H.","family":"Logan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1426-9599","authenticated-orcid":false,"given":"K.","family":"Lockhart","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Chong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,10]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-5347(17)36948-3"},{"key":"e_1_2_10_2_2","first-page":"1649","article-title":"Management of Urethral Catheter Knot in a Neonate","volume":"9","author":"Mayer E.","year":"2002","journal-title":"Canadian Journal of Urology"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.4103\/ua.ua_15_19"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/672326"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/2051415819896508"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.24953\/turkjped.2016.04.020"}],"container-title":["Case Reports in Urology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/criu\/5559138","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/criu\/5559138","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/criu\/5559138","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T18:55:03Z","timestamp":1773773703000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/criu\/5559138"}},"subtitle":[],"editor":[{"given":"Kalyani","family":"Sen","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/criu\/5559138"],"URL":"https:\/\/doi.org\/10.1155\/criu\/5559138","archive":["Portico"],"relation":{},"ISSN":["2090-696X","2090-6978"],"issn-type":[{"value":"2090-696X","type":"print"},{"value":"2090-6978","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2024-09-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-03-28","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-07-10","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"5559138"}}
