Objective. Analysis of current tendencies in the treatment of patients with submucosal uterine myoma. Results. Submucosal uterine myoma is often an indication for hysterectomy. At the same time, modern surgical methods allow performing organ-sparing interventions quickly and safely, including on an outpatient basis with the use of mini hysteroresectoscope. Accurate topographic diagnosis is an important condition for the successful implementation of organ-sparing treatment for submucosal myoma. When choosing diagnostic instruments, it is necessary to take into account their specificity and availability, which makes hydrosonography and hysteroscopy a priority, especially considering that endoscopic diagnostics can be supplemented by myoma resection, and the use of spectral analysis in image processing makes it possible to more accurately identify associated endometrial pathology. Conclusion. The use of mini-resectoscope (16 Fr) allows achieving a number of significant advantages in comparison with traditional hysteroresectoscopy. The use of spectral analysis in hysteroscopy provides more information about the state of the endometrium and intrauterine formations.
