Clinical success was defined as the absence of upper urinary tract catheterization, surgical repair or transplantectomy during follow-up.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 44 patients were included. The median time to US onset was 3.5\u00a0months (IQR 1.9\u201310.8), the median length of stricture was 10\u00a0mm (IQR 7\u201320). Management of US involved balloon dilation and laser incision in 34 (79.1%) and 6 (13.9%) cases, respectively, while 2 (4.7%) received both. Clavien\u2013Dindo complications were infrequent (10%); only one Clavien\u2009\u2265\u2009III complication was reported. Clinical success was 61% at last follow-up visit (median\u2009=\u200944.6\u00a0months). In the bivariate analysis, duckbill-shaped stenosis (vs. flat\/concave) was associated with treatment success (RR\u2009=\u20090.39, <jats:italic>p<\/jats:italic>\u2009=\u20090.04, 95% CI 0.12\u20130.76), while late-onset stenosis (&gt;\u20093\u00a0months post KT) with treatment failure (RR\u2009=\u20092.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.02, 95% CI 1.01\u20133.95).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Considering the acceptable long-term results and the safety of these procedures, we believe that the endoscopic treatment should be offered as a first-line therapy for selected KT patients with US.
