Endoscopic treatment consisted of injection of dextran hyaluronic acid copolymer (DX\/HA) into the ureteral opening under direct cystoscopy guidance.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Fifty-two children (35 males, 17 females) were included in this study, and for a total 90 ureters (14 unilateral, 38 bilateral) were diagnosed with vesicoureteral reflux by Voiding cystourethrography (VCUG). Twenty-two children were treated with antibiotics (8 unilateral, 14 bilateral), for a total of 36 ureters; thirty children were treated by endoscopic injection (6 unilateral, 24 bilateral), for a total of 54 ureters. The injection surgery took 36\u2009\u00b1\u200917\u00a0min including duration of general anesthesia and circumcision and the hospital stay was 2.3\u2009\u00b1\u20091.3\u00a0days. All male patients underwent circumcision simultaneously. There were no drug and allergic reactions in the antibiotic group, and no postoperative complications occurred in the injection group.\u00a0With 23\u00a0months (13\u201363\u00a0months) of mean follow-up, the resolution rate, defined as radiological disappearance of VUR, was 36.1% (13\/36) in the antibiotic group and 57.4% (31\/54) in the injection group (<jats:italic>P<\/jats:italic>\u2009=\u20090.048).Two cases of bilateral reflux in the injection group required a second injection before resolution could be achieved.\u00a0Thus, the overall success rate of injection was 64.8% (35\/54). 9 cases (9\/18, 50%)  in the antibiotic group had renal scars\u00a0on DMSA scans, while this was seen in\u00a020 cases (20\/23, 86.9%) in the injection group.\u00a0There was a statistically significant difference between the two groups (<jats:italic>P<\/jats:italic>\u2009=\u20090.010).The positive rates of ultrasound between the antibiotic group and the injection group were 45.5% (10\/22) and 80.0% (24\/30), respectively. There was a statistically significant difference between the two groups in positive rates of ultrasound (<jats:italic>P<\/jats:italic>\u2009=\u20090.010).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Endoscopic injection is easy to operate with short surgical time and hospital stay, so it is a safe and feasible treatment. For the treatment of primary vesicoureteral reflux in children, the radiological resolution rate of endoscopic injection is better than antibiotic therapy. In this study, the presence\u00a0of kidney scars on DMSA and the dilated of the collecting system on ultrasound are the indications for endoscopic injection.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00383-024-05780-3","type":"journal-article","created":{"date-parts":[[2024,7,12]],"date-time":"2024-07-12T12:02:23Z","timestamp":1720785743000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison and clinical analysis of antibiotics and endoscopic injection for vesicoureteral reflux in children"],"prefix":"10.1007","volume":"40","author":[{"given":"Zhen","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kanglin","family":"Dai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianglun","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Tian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lihua","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingsi","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ban","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick Ho Yu","family":"Chung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth Kak Yuen","family":"Wong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,7,12]]},"reference":[{"issue":"5","key":"5780_CR1","doi-asserted-by":"publisher","first-page":"981","DOI":"10.1111\/j.1464-410X.2006.06064.x","volume":"97","author":"JM Silva","year":"2006","unstructured":"Silva JM, Diniz JS, Lima E et al (2006) Predictive factors of resolution of primary vesicoureteral reflux: a multivariate analysis.
