Physical examination revealed percussion pain in the waist and abdomen. Laboratory examination showed that urine-occult blood was positive. No other obvious abnormalities were found. Computed tomography urography (CTU) showed that the ureter was obviously dilated, and the middle and lower segments of the ureter were dilated tortuously as “tumor like” (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>, arrows). The diagnosis of congenital megaureter was established. Considering that the patient had aggravation of abdominal pain and hematuria that may have been associated with urinary tract obstruction and infection, ureteroplasty and ureterovesical replantation were performed. Postoperative pathology showed thinning of the urinary tract epithelium (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>, arrows). The patient was discharged postoperatively within 12 days with no complications. The pain did not reoccur during the two-year follow-up.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">Congenital megaureter is a rare condition that often occurs in middle-aged men and is due to distal ureteral muscle abnormalities, thus leading to vesicoureteral obstruction. This anomaly is very rare in a 15-year-old female. Patients may be complicated with urinary calculi and urinary tract infections, and even the dilated ureter may be misdiagnosed as an abdominal mass. A preoperative CTU examination is necessary to avoid misdiagnosis. In the current case, the intermittent abdominal pain was caused by recurrent urinary tract infections. Surgery of megaureter tailoring plus ureteroneocystostomy is recommended. To reduce complications and shorten recovery time, pure laparoscopic and robot-assisted laparoscopic ureteral reimplantation can be selected.</p><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Ethical considerations</span><p id="par0025" class="elsevierStylePara elsevierViewall">The authors have obtained written informed consent.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Funding</span><p id="par0020" class="elsevierStylePara elsevierViewall">This work was supported by the <span class="elsevierStyleGrantSponsor" id="gs1">“Taishan Scholar”</span> Project (No. <span class="elsevierStyleGrantNumber" refid="gs1">tsqn202103197</span>), the <span class="elsevierStyleGrantSponsor" id="gs2">Natural Science Foundation of Shandong Province</span> (No. <span class="elsevierStyleGrantNumber" refid="gs2">ZR2022MH274</span>), the <span class="elsevierStyleGrantSponsor" id="gs3">Shandong Postdoctoral Science Foundation</span> (No. <span class="elsevierStyleGrantNumber" refid="gs3">SDCX-ZG-202303059</span>) and the <span class="elsevierStyleGrantSponsor" id="gs4">Yantai Science and Technology Innovation Project</span> (No. <span class="elsevierStyleGrantNumber" refid="gs4">2023YD002</span>).</p></span><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0015">Conflict of interest</span><p id="par0015" class="elsevierStylePara elsevierViewall">No author has any type of conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:3 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Ethical considerations" ] 1 => array:2 [ "identificador" => "sec0010" "titulo" => "Funding" ] 2 => array:2 [ "identificador" => "sec0005" "titulo" => "Conflict of interest" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:3 [ "etiqueta" => "1" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">H.
