OBJECTIVE: Urinary tract endometriosis affects 0.3-12 % of all cases of endometriosis. Medications have limited efficacy in treating advanced disease. Serous cystadenofibroma is a rare benign variant of ovarian epithelial tumors comprising …

BACKGROUND: The oral gonadotropin-releasing hormone antagonist relugolix, which temporarily stops menstruation, is used to treat heavy menstrual bleeding, pelvic pressure, and low back pain in women with uterine fibroids. Treatment can also…

Pyomyoma is an extremely rare complication, defined as an infection of a uterine leiomyoma. We describe two cases of pyomyoma that were initially considered to be tubo-ovarian abscesses but were later diagnosed as pyomyomas and managed with…

PURPOSE: To compare the effects of preoperative dienogest (DNG) and gonadotropin-releasing hormone (GnRH) agonist administration on the improvement of preoperative symptoms and surgical outcomes in patients who underwent laparoscopic cystec…

BACKGROUND/AIMS: Despite the benefits of laparoscopic surgery, which is being performed with increasing frequency, complications that do not occur during laparotomy are sometimes encountered. Such complications commonly occur during the ini…

BACKGROUND: Ovarian endometriomas affect a substantial proportion of women of reproductive age who may have a potential risk of diminished ovarian reserve (DOR) after ovarian cystectomy. Here, we investigated the risk factors for pre-surgic…

OBJECTIVE: We conducted a single-center study to evaluate the usefulness of the magnetic resonance (MR) imaging jelly method for diagnosing endometriosis-associated adhesions in the Pouch of Douglas. METHODS: Thirty women with menstrual pa…

AIM: The rate of oocyte decline follows a biphasic pattern, characterized by acceleration between 32 and 38 years old. Ovarian reserve is also affected by external factors, including ovarian disease and iatrogenic damage. The aim of this st…

UNLABELLED: BACKGROUND AND OBJECTS: To examine the learning curve of minimally invasive 2-port total laparoscopic myomectomy (TTLM). METHODS: TTLM was performed by using only umbilicus and left inguinal ports, for 30 patients at our univer…

PURPOSE: To evaluate preoperative magnetic resonance (MR) imaging features of bleeding and non-bleeding ectopic pregnancy (EP) by comparison with surgical findings. METHODS: Eighteen suspected EP cases underwent preoperative MR imaging. We…

There are two different types of hysterocopes available: Flexible and rigid. Flexible scopes have the ability to observe the whole intrauterine cavity, but it is difficult to perform an operation on endometrial lesions. Rigid hysteroscopes …

OBJECTIVE: To define diagnostic criteria for juvenile cystic adenomyoma (JCA), describe the histologic features of the condition and evaluate laparoscopic excision for treating associated dysmenorrhea and pelvic pain. DESIGN: Prospective l…

Objective: To assess the attributes and feasibility of conservative laparoscopic surgery for patients with ruptured ovarian endometrioma.Design: Retrospective analysis.Setting: University medical center.Patient(s): Eighteen patients undergo…
