Endometriosis is a chronic gynecological disorder characterized by the ectopic presence of endometrial tissue, often resulting in pelvic pain, infertility, and decreased quality of life. Magnetic Resonance Imaging (MRI) plays a crucial role in noninvasive diagnosis and preoperative assessment of endometriosis, particularly in evaluating complex or deep infiltrative diseases. A detailed and structured report on lesion depth, extension, and involvement of critical anatomical structures is vital for multidisciplinary teams’ decision-making. By comprehensively understanding and recognizing the complete range of endometriosis manifestations, radiologists can significantly enhance individualized treatment strategies and improve patient outcomes. This pictorial review highlights the key MRI features of endometriosis and provides essential guidance for radiologists during the imaging and reporting process.

Objectives: We aimed to evaluate the risk factors for the conversion from laparoscopic partial nephrectomy (LPN) to open surgery to achieve partial nephrectomy (PN). Methods: Data from patients who underwent LPN between June 2020 and September 2023 were analyzed retrospectively. Patients in whom the PN procedure could be completed laparoscopically were recorded as the ‘Fully Laparoscopic’ (FL) group (n = 97), and those converted to open surgery from laparoscopy were recorded as the ‘Conversion to Open’ (CTO) group (n = 10). The demographic and pathologic variables were compared between groups. Regression analyses were used to define predictor factors, and receiver operating characteristic analysis was used to define the cut-off value of the surgical bleeding volume. Results: Conversion to open surgery was found in 10/107 patients (9.3%). There was no statistical difference between groups in demographic and pathologic variables. Intraoperative blood loss volume, upper pole localized tumor, and posterior localized tumor were found to be statistically higher in the CTO group (p = 0.001, p = 0.001, and p = 0.043, respectively). Furthermore, these factors were only found to be statistically significant predictors of conversion to open surgery in both univariate and multivariate regression analyses. 235 cc was found to be the cut-off value of intraoperative blood loss volume for predicting conversion to open surgery (p = 0.001). Conclusion: Using these predictive factors in clinical practice, treatment planning will lead to the possibility of starting the treatment directly with open surgery instead of minimally invasive options, and it may also provide a chance of being prepared for the possibility of conversion to open surgery peroperatively.
