A 35-year-old gravida 7, para 1, and abortus 5 female with hypogastric pain and inability to void urine after 14 + 3 weeks of amenorrhea was examined in the emergency department. One year before, a uterine prolapse had been diagnosed in another hospital.\nExamination showed an anteverted uterus and uterine prolapse grade 2 with palpable bladder. The patient was unable to void urine. Ultrasound revealed a cervical length of 30 mm and a singleton, cephalic fetus. A manual reduction of the uterine prolapse was made, and the patient underwent an emergency catheterization for bladder drainage (500 mL urine). No urinary tract infection was found. Then, it a Hodge pessary (size 70), and was placed after a spontaneous micturition, the woman was discharged for further ambulatory followup. The following day, the patient was admitted in to the emergency department because of a new AUR. Hodge pessary was replaced by another one of size 75, and due to the persistence of the symptoms, finally an Arabin cerclage pessary was placed (). The patient was discharged after a rapid resolution of symptoms.\nObstetric controls, which included vaginal cultures, were made every two weeks during the whole pregnancy. With negative vaginal cultures, the pregnancy progressed without incidences. The woman was admitted into the hospital at 36 + 5 weeks of gestation, due to a premature rupture of membranes. No evidence of vaginal infection was found. Then, Arabin cerclage pessary was removed, and the patient underwent a vaginal delivery, giving birth to a boy weighing 2,650 g.
A 26-year-old woman followed the course approximately similar to the Case one. She experienced urinary retention requiring urethral catheterization, which drained 900 ml of clear urine, at 12 weeks of her first pregnancy. Transvaginal sonography also revealed a retroverted uterus. The same prophylactic measures were suggested to the patient. Until 14 weeks’ gestation, urinary retention requiring urethral catheterization recurred two times. At 16 weeks’ gestation, the gravid uterus was examined and no retroversion was observed anymore. She had no recurrence of urinary retention during the rest of this pregnancy. Two years later, she consulted our hospital again due to urinary retention at 11 weeks of her second pregnancy.
