There were 22 women and four men (mean age 44.7\u00a0\u00b1\u00a011.3\u00a0years). One patient had stricture of the lumbar ureter because of a gunshot wound. He underwent substitution of the upper third of the right ureter with the appendix. In the other cases, we carried out substitution of the pelvis part of the ureter with appendix, in four cases from the left side. In the last 22 cases, a novel surgical technique for better appendicovesical anastomosis was carried out: a flap was dissected from the dome of the cecum to increase the diameter of anastomosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The postoperative follow\u2010up period was from 1 to 21\u00a0years.

In another two cases associated with similar complications, endoureterotomy and ureteral stenting were carried out. One patient was managed with percutaneous nephrostomy. Kidney function was restored in all patients. Good short\u2010term results were achieved in 22 patients (84.6%) and long\u2010term (from 1 to 21\u00a0years) results in 25 patients (96.2%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In patients with long ureteral stricture, the use of the appendix can help to restore the function of the upper urinary tract.<\/jats:p><\/jats:sec>","DOI":"10.1111\/iju.14268","type":"journal-article","created":{"date-parts":[[2020,6,1]],"date-time":"2020-06-01T02:10:20Z","timestamp":1590977420000},"page":"663-669","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Ureteral substitution with appendix"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8606-9791","authenticated-orcid":false,"given":"Boris","family":"Komyakov","sequence":"first","affiliation":[{"name":"Department of Urology North\u2010Western State Medical University named after I.I.
