In the United States, injuries from the use of sex-related instruments are a very common reason for emergency room visits [
1,
2]. Insertion of the instrument and its penetration through the vaginal wall regularly result in the object penetrating the abdominal cavity [
3,
4], leading to possible bowel damage. It is rare for large objects to enter and become trapped in the bladder [
5].
A 29-year-old G1 Po Ab1 Caucasian woman visited the emergency room at about 1 A.M. and reported that her vibrator had become lost during sexual activity. The patient said that her partner suddenly started vaginal intercourse after using the vibrator to stimulate the clitoris directly. The patient was uncertain about the location of the vibrator and felt discomfort for a while. She thought the vibrator was in the vagina as sexual intercourse progressed because she could still feel the vibration. After intercourse, the patient could not find the vibrator in the vagina but still felt the sensation of vibration within the pelvis. When the patient was unable to find the vibrator, she presented to the emergency room. She stated that the vibration lasted about 30 minutes, approximately the battery life of the device. An X-ray of the pelvis showed that the vibrator was approximately at the level of the intrauterine device of the patient within pelvis and in the horizontal position.
Careful questioning of the patient revealed that the vibrator was an unusual type called Vesper™ (Crave Corp., Bloomington, MN, USA), which has an unusually small diameter of approximately 1.2 cm. The device is approximately 10 cm long and on a chain to be worn like a necklace, maximizing the ease of use of the vibrator. The chain can be removed to use the vibrator for sexual activity. The patient confirmed that she removed the chain from the device before use.
Repeated vaginal and rectal examinations by the emergency room staff and gynecologists did not show evidence of the device in either the vagina or the rectum, so it was assumed that the device passed through the vaginal wall and entered the abdominal cavity. The patient had a body mass index of 22.5, so it was believed that her weight did not affect the examinations. It was assumed that the colon had not ruptured because of the limited softness found on examination. However, before laparoscopic exploration, the patient agreed to undergo a colostomy and repair of the colon if found necessary. Laparoscopic exploration showed that the device was in the bladder. Its location was also demonstrated by moving a sponge stick placed in the vagina and by gently manipulating the poly bulb. The vibrator was visualized and removed with a cystoscope.
To safely remove the vibrator through the urethra, it was necessary to fill the bladder with about 1 L of normal saline to change the orientation of the vibrator from horizontal to vertical, resulting in no morbidity from removal. The patient recovered without incident immediately after removal of the foreign body and was discharged from the hospital.
To provide the highest level of care when treating a patient with a foreign body, it is important to understand, as much as possible, the object in question [
6-
8]. Most gynecologists are familiar with sex-related injuries and associated morbidities. In situations similar to that of our patient, most gynecologists generally assume that the vibrator will be too large to fit through the urethra [
9-
12]. In our case, the vibrator was measured to have an maximum diameter of about 1.2 cm, which is about the same as the diameter of a 36 French catheter. Thus, the device was able to enter the urethra and occupy the bladder without damaging it [
13,
14].
Another interesting aspect of this case was that the device was assumed to be in the pelvic cavity because it appeared on the X-ray to be approximately at the level of the intrauterine device. Retrospectively, we believe that if a computed tomography scan had been performed or a lateral X-ray taken, the radiologist might have been able to accurately locate the device. Thus, the patient could have been spared the laparoscopy because the device could have been removed with a simple cystoscopy.
