<p>We aimed to present a case of urinary retention that develops after caesarean delivery and persists for 33 days.</p><p>A 35-year-old G4P2 41-week-old pregnant woman applied to our clinic because she could not urinate on the 4th day after cesarean section. After the examination, it was determined that urine retention developed in the patient. Neostigmine and meropenem treatment was applied. With intermittent catheterization, spontaneous urination started to take place on postpartum day 33.</p><p>Postpartum urinary retention, which causes maternal morbidity, is a common condition in obstetric care. Therapy is followed by bladder catheterization, antibiotic therapy and periodic catheter withdrawal, and spontaneous massing of the patient is followed and residual urine is checked by ultrasonography after the mass.</p>

Mature cystic teratomas (MCT) are composed of a mixture of tissues derived from all three germ layers and are the most common ovarian tumor in both adolescents and women of reproductive age. Although most of these tumors are benign, malignant transformation of MCT occurs only in about 1-2% of cases. Any of the tissues within the MCT, can change malignant transformation. Struma ovarii is a rare ovarian tumor, reported as %0.5-1 of all ovarian masses and <3% of MCT's. Less than 5% of struma ovarii present malignant transformation. We reported a 66 year-old postmenopausal woman who was admitted for routine control. We revealed solid-cystic mass in the right adnexa that suggested teratoma. We performed total abdominal hysterectomy and bilateral salpingooophorectomy and thyroid papillary carcinoma was determined in pathological assesment. It is difficult to determine the diagnosis prior to surgery, final pathological diagnosis was confirmed as struma ovarii based on the typical morphology of the thyroid follicles and the results of immunohistochemical staining.
