A 34-year-old, gravida 0 para 0 Japanese woman visited a regional hospital complaining of dysmenorrhea, hematuria during menstruation, and right inguinal pain. She had a history of dysmenorrhea and three prior rounds of in vitro fertilization with embryo transfer, which were all with transfers of cryopreserved-thawed single embryos in natural cycles, resulting in no pregnancy. An ultrasound revealed a large 2 × 1-cm nodule between the bladder and the anterior wall of the uterus and a 3-cm cystic lesion in the right adnexal area. A combined cystoscopic and laparoscopic resection of the bladder endometriosis and cystectomy of the right endometrioma were carried out. A single ultrasound-guided transfer of a cryopreserved-thawed embryo in the cleavage stage was performed 4 months postoperatively, which resulted in an uncomplicated pregnancy. The combined, single procedure was minimally invasive and eradicated the lesions that may have caused the infertility.
Keywords: bladder endometriosis; cystoscopy-assisted laparoscopic resection; pregnancy.
