The intrauterine device (IUD) is common method of contraception among women because of its low cost and high efficacy. Perforations are possible; most perforations occur at the time of insertion, yet the complication can occur with a previously inserted IUD. Perforation of the bladder by an IUD is extremely rare. In this report, we present a case in which the IUD perforated the uterus and migrated to the bladder. At the time of the diagnosis, the patient was 8 weeks pregnant.

Background: Several studies have suggested that the menstrual cycle has an impact on postoperative nausea and vomiting (PONV). No previous study has evaluated the effect of the menstrual cycle on the incidence of postoperative agitation and analgesic/antiemetic requirements. Methods: On the basis of the phase of the menstrual cycle [pre±menstrual (Pd 25–6), early follicular phase (Pd 8–12), ovulatory phase (Pd 13–15), and luteal phase (Pd 20–24)], 67 patients enrolled in this blinded, prospective study. Anesthesia was standardized. Fentanyl was given to the patients who had severe pain in the recovery room. The patients who had agitation were given midazolam. When pain intensity was >5 on the Visual Analog Scale, metamizol was administered in the Gynecology Department. A blinded anesthesiologist recorded episodes of PONV in the recovery room, and 2 and 24 h postoperatively. Results: The opioid requirement and the frequency of agitation were similar in each group. Metamizol consumption was highest in the luteal phase (p < 0.05). The follicular and luteal phases were predictors for vomiting at recovery (p < 0.05 and p < 0.001, respectively). At the postoperative 2nd hour, nausea was higher in the follicular phase than in the other phases (p < 0.05) and the luteal phase was a predictor for retching (p < 0.001). At the postoperative 24th hour, nausea was the common symptom in the luteal phase (p < 0.05). The need for ondansetron was highest in the luteal phase (p < 0.01). Conclusions: In conclusion, we suggest that the scheduling of all surgical procedures according to the menstrual phase may serve to reduce the incidence of PONV and metamizol/ondansetron consumption and hospital costs.
