Incarceration of the gravid uterus: a case report and literature review

Abstract

Abstract Background Incarceration of the gravid uterus is a rare obstetric disorder that contributes to pregnancy-related complications. To understand its clinical characteristics and managements, we have reviewed the etiology, risk factors, clinical characteristics and current treatments of an incarcerated gravid uterus based on 162 cases reported in the English language literature, including our patient. Case presentation A 25-year-old primigravida, with a history of lymphatic tuberculosis, infertility due to blocked fallopian tubes and received in vitro fertilization. The patient presented with urine retention and lower abdominal pain in the early second trimester. Uterine incarceration was diagnosed based on pelvic examination and abdominal ultrasound. A Foley catheter was placed and manual reposition was successful. No episode of retention was experienced after the further enlargement of the uterus and its ascent. A healthy infant was delivered vaginally on 38th week of pregnancy. Conclusions Uterine incarceration due to pelvic adhesions is rare and, because of it non-specific clinical presentations, is often misdiagnosed. Abdominal ultrasound is instrumental for the diagnosis because it can directly image the disturbed uterine and pelvic anatomy. There are limited treatment options for uterine incarceration, but definitive diagnosis allows procedures to treat and to reduce severe complications of uterine incarceration.
