We also reviewed if increasing exchange time interval from 6 to 12\u00a0weeks was safe, and if this could be adopted into our local guidelines.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A retrospective review was performed covering 24\u00a0months from January 2017 to December 2018. All NUS insertions and exchanges performed in that period were analysed, including the number of exchanges the patient underwent, the time between subsequent exchanges, and the screening time. We also reviewed the indications for stent insertion, possible causes for failed stent exchange, and factors which led to significant delays in stent exchanges for some patients. A scatterplot of screening time versus time in situ was derived and correlation analysis performed using the Pearson coefficient.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Thirty-two patients underwent de novo NUS insertion during the period, and 102 NUS exchanges were performed. The interval between stent exchanges ranged from 1 to 40\u00a0weeks, with a mean of 12.3\u00a0weeks (SD\u2009=\u20098.96\u00a0weeks). Screening time ranged from 33\u00a0s to 17\u00a0min, with a mean of 3\u00a0min 50\u00a0s (SD\u2009=\u20093\u00a0min 35\u00a0s). There were 100 successful exchanges, and two failed exchanges, accounting for 1.9% of total exchanges. In both failed cases, the reason for failed exchange was due to a prolonged period between exchanges (6\u00a0months in both cases). The reason for delay for stent exchange was due to\u00a0non-attendance for scheduled appointments. There was a weakly positive correlation coefficient of 0.06 (screening time versus time period between insertions); however, this was not statistically significant (p\u2009=\u20090.81).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>In this retrospective review, we have demonstrated that the recommended 6-week period between stent exchanges is unnecessary in the vast majority of cases, and that a longer interval between NUS exchanges, e.g. 8\u201312\u00a0weeks, is safe for the patient, and reduces screening time. This reduction in procedures also provides a significant potential saving to the radiology department in both monetary expense and limited angiography suite time.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s11845-021-02657-5","type":"journal-article","created":{"date-parts":[[2021,6,5]],"date-time":"2021-06-05T21:02:26Z","timestamp":1622926946000},"page":"1349-1353","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Safely increasing nephro-ureteric stent exchange intervals, resulting in significant cost savings for the interventional radiology suite, a 2-year experience in a tertiary referral centre"],"prefix":"10.1007","volume":"191","author":[{"given":"Emma","family":"Tong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kate","family":"Hunter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joe","family":"Deegan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William C.","family":"Torreggiani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,6,5]]},"reference":[{"issue":"2","key":"2657_CR1","doi-asserted-by":"publisher","first-page":"77","DOI":"10.1097\/01.mou.0000193375.29942.0f","volume":"16","author":"M Duvdevani","year":"2006","unstructured":"Duvdevani M, Chew B, Denstedt J (2006) Minimizing symptoms in patients with ureteric stents.
