Uterine inversion caused by uterine sarcoma: a case report. (1/8)

Uterine inversion caused by uterine sarcoma is a rare condition with 12 reported cases to date according to a MEDLINE search. We report two cases of this rare condition. A 71- and a 72-year-old woman presented with uterine sarcomas rapidly extruded into the vagina. In both cases, magnetic resonance imaging (MRI) scans showed U-shaped uterine cavities and the pedicles of these tumors were attached to the uterine fundi. Pathological examination confirmed a leiomyosarcoma and a heterologous carcinosarcoma. Uterine inversion can occur when uterine sarcoma rapidly increases in size and extrudes into the vagina. MRI should be performed in the diagnosis of this rare combination.  (+info)

Puerperal uterine inversion and shock. (2/8)

Uterine inversion is an unusual and potentially life-threatening event occurring in the third stage of labour. It is associated with significant blood loss, and shock, which may be out of proportion to the haemorrhage, although this is questionable. When managed promptly and aggressively, uterine inversion can result in minimal maternal morbidity and mortality. A recent case is described, followed by a short review of the literature.  (+info)

Sonographic findings in acute urinary retention secondary to retroverted gravid uterus: pathophysiology and preventive measures. (3/8)

OBJECTIVES: To explore the pathophysiology of acute urinary retention in women with a retroverted gravid uterus and to suggest measures to prevent its recurrence. METHODS: In five women with a retroverted gravid uterus and acute urinary retention necessitating catheterization, the morphology of the genitourinary system was assessed by using transabdominal, transvaginal and introital sonography. RESULTS: In the supine resting position, the cervix was displaced superiorly and anteriorly by the impacted and retroverted uterus so that it compressed the lower bladder, leading to obstruction of the internal urethral orifice. The upper bladder extended superiorly and overlay the uterus. During straining, urethral motion was not limited and there was an average rotational angle of the bladder neck of 32 degrees, ranging from 21 degrees to 44 degrees. Increasing abdominal pressure further compressed the lower bladder. Measures suggested to the women for the prevention of urinary retention included limiting fluid intake before sleep, changing from the supine to the prone position before getting up and avoiding a Valsalva maneuver but performing a Crede maneuver during voiding. In all except one case these measures successfully prevented recurrence. CONCLUSIONS: Acute urinary retention secondary to a retroverted gravid uterus is caused by a displaced cervix compressing the lower bladder and interfering with drainage to the urethra. The urethra itself is not compressed or distorted. Understanding the pathophysiology of the lower urinary tract may allow maneuvers which prevent acute urinary retention.  (+info)

Septic postpartum uterine inversion. (4/8)

Puerperal uterine inversion is an uncommon but life threatening obstetrical emergency. A 26-year-old woman, para six, was referred from a peripheral hospital seven days after delivery, with a mass protruding per vaginum. Complete uterine inversion had occurred after delivery of baby and placenta. She was resuscitated and her genital infection was treated. She had a vaginal hysterectomy upon request. Her postoperative recovery was uneventful. Poor management of the third stage of labour is a common cause of uterine inversion. Early replacement of the inverted uterus is important to prevent further complications.  (+info)

Neglected puerperal inversion of the uterus: ignorance makes acute a chronic form. (6/8)

Inversion of uterus is a rare complication of vaginal delivery. The reported incidence of puerperal inversion varies from approximately 1 in 550 to 1 in several thousand normal deliveries. Maternal mortality has been reported to be as high as 15%, mainly because of associated life threatening blood loss and shock. Early diagnosis, prompt and aggressive management decrease the morbidity and mortality to minimal. We report a case of 21 year old primi, who presented to us with uterine inversion after delivery at a rural set up by untrained birth attendant ("Dai"). She was managed surgically with Haultain's operation and discharged after 5 days. She didn't turn up for follow up and was readmitted after 4 weeks with uterine reinversion associated with endometritis. A recent case is described, followed by a short review of literature.  (+info)

Ovulation defect and its restoration by bone marrow transplantation in osteopetrotic mutant mice of Mitf(mi)/Mitf(mi) genotype. (7/8)

Mutation within the Mitf gene causes, in microphthalmic Mitf(mi)/Mitf(mi) (mi/mi) mice, multiple defects, including white coat color and functional defects in macrophages and osteoclasts. Our previous mating experiments have demonstrated that the mi mutation reduces the numbers of newborns and induces uterine inversion at delivery. The present study was designed to determine the causes of these pregnancy defects. The histology and number of F4/80-positive macrophages were not different between the ovaries of 23-day-old mi/mi and +/+ mice given eCG 48 h earlier. When ovulation was induced in these mice by hCG, the number of ovulated ova was significantly smaller in mi/mi mice than in wild-type (+/+) mice (p < 0.05). When bone marrow cells from +/+ mice were transplanted i.p. into 42 mi/mi female newborns, successful transplantation was observed in 16 of them at 20 days after birth. In one of these, the upper incisors had erupted. The mean number of tubal ova in mi/mi mice significantly increased after transplantation (p < 0.05) and was almost equal to that of +/+ mice. No uterine inversion occurred at 6 deliveries in 5 mi/mi females after bone marrow transplantation, while it occurred at 4 of 5 deliveries in mi/mi females during the same observation period (p < 0.05). These results indicate that bone marrow-derived cells, defective in mi/mi mice, are necessary for normal ovulation and delivery; the findings are consistent with the notion that macrophages play major roles in ovulation.  (+info)

O'Sullivan's hydrostatic reduction of an inverted uterus: sonar sequence recorded. (8/8)

A case of acute uterine inversion which was successfully managed with hydrostatic reduction is reported. A sequence of sonograms demonstrating this is presented, as far as we are aware, for the first time.  (+info)
