Herein, we describe four cases of undescended ovary during laparoscopic surgery with abnormal anatomy of fallopian tube, yet without abnormal uterine development and urinary system abnormalities, which are analyzed by their clinical features and effects on reproductive function.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>For the patients with undescended ovary, the location of unilateral or bilateral upper poles of the ovaries were usually much higher than that of the bifurcation of the common iliac vessel, and the fallopian tubes at the same side opened in the para-colonic sulcus. Among these four patients, two patients had primary infertility, one patient had tubal pregnancy rupture and bleeding, and one patient had uterine leiomyoma. The development of uterus was normal in all cases, and there was no abnormal development of urinary system. During the infertility examination, the fact that fallopian tubes lifted up in hysterosalpingography (HSG) might be regarded as an indicator of possible undescended ovary. The pelvic ultrasonography examination was of limited use in diagnosing undescended ovary.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Laparoscopy is the gold standard for the diagnosis of undescended ovary. When there is periodic post-sacral spinal pain, MRI or HSG can be used for diagnosis of undescended ovary.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13048-021-00898-7","type":"journal-article","created":{"date-parts":[[2021,11,22]],"date-time":"2021-11-22T12:02:52Z","timestamp":1637582572000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Undescended ovary without abnormal development of uterus and urinary system: a report of four cases"],"prefix":"10.1186","volume":"14","author":[{"given":"Weixia","family":"Wei","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenji","family":"Luo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qicai","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liping","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruifang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,11,22]]},"reference":[{"issue":"1","key":"898_CR1","doi-asserted-by":"publisher","first-page":"189","DOI":"10.1016\/S0015-0282(16)58050-9","volume":"65","author":"BS Verkauf","year":"1996","unstructured":"Verkauf BS, Bernhisel MA.
