Large bladder leiomyoma: a case report

The incidence of mesenchymal bladder tumors is 1—5 %; of them, 0.43 % are bladder leiomyomas. The choice of treatment strategy primarily depends on the size and location of the tumor. Small endovesical leiomyomas can be removed by transurethral resection of the bladder, while in case of large (>5 cm) intramural or extravesical leiomyomas, laparoscopic resection is more effective. In this article, we report a case of large (>7 cm) bladder leiomyoma in a 28-year-old female patient. The patient has undergone laparoscopic resection of the bladder at P.A. Herzen Moscow Oncology Research Institute.
