Urothelial carcinoma in both adnexa following perforation during transurethral resection of a non-muscle-invasive bladder tumor: a case report and literature review.

In this article case report of urothelial carcinoma implantation in both adnexa is reported, following a perforation of the bladder wall during a transurethral resection of a bladder tumor. The 81-year-old female patient had an extensive history of multiple recurrent non-muscle-invasive urothelial carcinoma of the bladder. Intraperitoneal perforation was detected and managed conservatively. Fifteen months after the procedure, the patient presented at the gynecology department with a mass in the left adnex, which was suspicious for malignancy, for which she subsequently underwent hysterectomy in combination with bilateral resection of the adnexa. Pathology showed papillary urothelial carcinoma in both ovaries. A literature search was performed to present an up-to-date review of the available data on bladder perforations during transurethral resection of the bladder and tumor implantation, its management and oncological outcomes.
