There were 6 males and 1 female from 7.7 to 13.9 years old at the mean age of 10.4. Before surgery, all children performed urinary B ultrasound, magnetic resonance urography (MRU), and renal radionuclide scanning. Six cases were observed on the left lateral and 1 on the right. The lesions of 5 cases were located at the ureteropelvic junction, 1 in the upper ureter and 1 in the middle ureter. The polyps were treated intraoperatively by the resecting of the lesion segment and simple polypectomy to retain the attached part of the original diseased segment of the ureter. All surgeries were performed under laparoscopy and B-ultrasound was performed during follow up after surgery.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> All 7 surgeries were performed successfully under the laparoscope. The surgery time was 80\u2013110 min, and the average surgery time was 97.5 min. The intraoperative bleeding was 10\u201325 ml and the average postoperative hospital stay was 6 d. Postoperative hematuria occurred in 1 case. Neither urinary leakage nor urinary tract infection was reported post surgery. Preoperative affected pyelectasis of all patients was 2.0\u20133.7 cm. Three months postoperatively, the affected pyelectasis was measured at 1.2\u20133.0 cm. No recurrence of polyps was reported after surgery. During the follow-up to April 2020, there was no significant change in the kidney size of all patients, and hydronephrosis was alleviated compared with that before surgery.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Laparoscopy is a safe, effective and minimally invasive surgical technique for pediatric multiple ureteral polyps. The surgery plan was designed according to the location and size of polyps, including segmental ureterectomy of polyps + pyeloureterostomy, segmental ureterectomy of polyps + ureter - ureteral anastomosis.<\/jats:p>","DOI":"10.3389\/fped.2021.689842","type":"journal-article","created":{"date-parts":[[2021,6,30]],"date-time":"2021-06-30T05:13:22Z","timestamp":1625030002000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Experience Summary of Laparoscopic Treatment for Pediatric Ureteral Polyps"],"prefix":"10.3389","volume":"9","author":[{"given":"Hongjie","family":"Gao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiawei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guowei","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinhai","family":"Cui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengyin","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,6,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"810","DOI":"10.1016\/S0090-4295(03)00691-5","article-title":"Elldoscopic treatment of fibroepithelial polyps of the renal pelvis and ureter","volume":"62","author":"Lam","year":"2003","journal-title":"Urology."},{"key":"B2","doi-asserted-by":"publisher","first-page":"22","DOI":"10.1016\/j.jpurol.2014.08.004","article-title":"Diagnosis and management of ureteral fibroepithelial polyps in children: a new treatment algorithm","volume":"11","author":"Li","year":"2015","journal-title":"J Pediatr Urol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"77","DOI":"10.1089\/cren.2019.0016","article-title":"Endoscopic treatment of fibroepithelial polyp of the ureter: case report","volume":"5","author":"Astroza","year":"2019","journal-title":"J Endourol Case Rep."},{"key":"B4","doi-asserted-by":"publisher","first-page":"358","DOI":"10.1055\/s-2004-815825","article-title":"Multiplefibroepithelial polyps of the upper Hreter in a 17 year_old boy case report and review of their terature","volume":"14","author":"Zeman","year":"2004","journal-title":"EurJ Pediatr Surg."},{"key":"B5","doi-asserted-by":"publisher","first-page":"345","DOI":"10.1055\/s-2004-821212","article-title":"Ureteral polyp causing ureteropelvic junction obstruction","volume":"14","author":"Menon","year":"2004","journal-title":"EurJ Pediatr Surg."},{"key":"B6","doi-asserted-by":"publisher","first-page":"1834","DOI":"10.1097\/01.ju.0000061966.21966.94","article-title":"Fibroepithelial polyps causing ureteropevic junctiion obstruction in children","volume":"169","author":"Adey","year":"2003","journal-title":"J Urol."},{"key":"B7","doi-asserted-by":"publisher","first-page":"80","DOI":"10.3346\/jkms.1996.11.1.80","article-title":"Fibroepithelial ureteral polyp case report:endoscopic removal of large ureteral polyp.","volume":"4","author":"Kim","year":"1996","journal-title":"J Korean Med Sci"},{"key":"B8","doi-asserted-by":"publisher","first-page":"718","DOI":"10.1111\/j.1445-2197.2008.04630.x","article-title":"Fibroepithelial polyp of the upper third of ureter","volume":"2","author":"Radojicic","year":"2008","journal-title":"ANZ J Surg."},{"key":"B9","doi-asserted-by":"publisher","first-page":"162","DOI":"10.1016\/j.jpurol.2007.07.006","article-title":"Lapamscopic pyloplasty:role of preoperative retrography pyelography.","volume":"4","author":"Golda","year":"2008","journal-title":"J Pediatr Urol"},{"key":"B10","doi-asserted-by":"publisher","first-page":"413","DOI":"10.1016\/j.urology.2005.08.020","article-title":"Endoscopic management of 10 separate fibroepithelial polyps arising in a single ureter.","volume":"67","author":"Carey","year":"2006","journal-title":"Urology."},{"key":"B11","doi-asserted-by":"publisher","first-page":"14580","DOI":"10.5812\/ijp.4293","article-title":"A giant ureteral polyp mimicking as a bladder mass resected ureteroscopically by diode laser: a case report and literature review","volume":"8","author":"Liu","year":"2015","journal-title":"Int J Clin Exp Pathol."},{"key":"B12","doi-asserted-by":"publisher","first-page":"E631","DOI":"10.5489\/cuaj.2878","article-title":"Treatment and outcome of fibroepithelial ureteral polyps: a systematic literature review","volume":"9","author":"Ludwig","year":"2015","journal-title":"Can Urol Assoc J."},{"key":"B13","doi-asserted-by":"publisher","first-page":"896","DOI":"10.1089\/end.2016.0006","article-title":"Lendvay TS.
