The ETSUTT procedure consisted of a modified extravesicular technique (two\u2010layer, side\u2010to\u2010side ureteroneocystostomy) and tension\u2010relieving techniques (renal descensus, ureterocystopexy, and nephrocystopexy).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All cats survived through discharge. In all cats, postoperative blood urea nitrogen and creatinine concentrations were decreased, compared with preoperative concentrations. Perioperative complications included ureteral catheter dislodgement (3), transient pollakiuria (2), and dysuria (1), but no specific treatments were required. Urinary tract infection was observed postoperatively in three of the 10 cats. The median follow\u2010up was 648\u2009days (min\u2013max: 86\u20131229\u2009days).
