A 34-Week Size Uterus with a Complete Hydatidiform Mole: Hook Effect and Severe Anemia with No Vaginal Bleeding

Atypical presentation of hyperthyroidism complicated complete hydatidiform mole in a 24-year-old female: a case report

Introduction and importance

Molar pregnancy is the most common type of gestational trophoblastic disease. It manifests as vaginal bleeding, accompanied by high levels of β-human chorionic gonadotropin (β-HCG). This case aims to highlight the importance of considering gestational trophoblastic disease as a potential diagnosis and its serious complications.

Case presentation

A 24-year-old female presented with vomiting, nausea, and no complaint of vaginal bleeding. Laboratory tests indicated hyperthyroidism as a complication requiring challenging preoperative prophylactic management. Initially, the patient underwent suction and curettage, but a total hysterectomy had to be performed later. The histological study concluded with the diagnosis of a complete hydatidiform mole. Post-surgery follow-up evaluations revealed high blood pressure values, and the patient was appointed for further cardiology assessment.

Discussion and conclusion

Although uncommon, complications of a molar pregnancy include anaemia, severe cardiac distress, and hyperthyroidism. Trophoblastic Hyperthyroidism is a result of extremely high levels of β-HCG levels due to molecular cross-reactivity. History, clinical examination, and ultrasound, in addition to measuring β-HCG levels, could all help in diagnosing a molar pregnancy, but the definitive diagnosis is based on histopathology and a karyotype study. Management procedures include dilation, suction and curettage, and hysterectomy. The treatment depends on the patient's age, desire for future pregnancies, and risk of developing gestational trophoblastic neoplasia. A follow-up with serial β-HCG measurement is recommended to monitor possible complications. Attaining and maintaining euthyroidism is a life-saving procedure before molar pregnancy surgery. Methimazole, Propranolol, Lugol's iodine, and hydrocortisone can all be used in the prophylactic management of the thyroid storm.

Risk factors of uterine contraction after ureteroscopy in pregnant women with renal colic

Background

Ureteroscopy is widely applied in pregnant women with renal colic, but such patients are easy to experience uterine contraction after surgery. There are many factors which may affect uterine contraction, this study aims to explore the risk factors of uterine contraction triggered by ureteroscopy in pregnant women with renal colic.

Methods

One hundred and one pregnant women were retrospectively analyzed, the patients were hospitalized because of severe renal colic. All patients received ureteroscopy during which double J catheters were inserted into ureters for drainage. Patients received other medical treatments individually according to their condition and uterine contractions were detected by EHG within 12 h after operation. Patients were classified as group A (uterine contraction) and group B (no uterine contraction) according to the presence or absence of continuously regular uterine contraction. Clinical characteristics were collected for further analysis, including history of childbirth, anesthesia method, application of phloroglucinol or not, operation time, Oxygen inhalation or not, pain relief or not after surgery, systemic inflammatory response syndrome (SIRS) occurred or not. A binary logistic regression analysis model was established to explore whether such clinical characteristics were relevant to uterine contraction after ureteroscopy.

Results

Continuously regular uterine contraction presented in 46 pregnant women within 12 h after ureteroscopy, making the incidence of uterine contraction as high as 45.54%. The presence of uterine contraction was related to the following factors(P < 0.05): history of childbirth (primipara versus multipara)(OR 6.593, 95% CI 2.231–19.490), operation time (each quarter additional) (OR 2.385, 95% CI 1.342–4.238), application of phloroglucinol (yes versus not) (OR 6.959, 95% CI 1.416–34.194), pain relief after surgery(yes versus not)(OR 6.707, 95% CI 1.978–22.738), SIRS occurred after surgery (yes versus not) (OR 0.099, 95% CI 0.014–0.713).

Conclusion

Continuously regular uterine contraction is easy to occur within 12 h after ureteroscopy in pregnant women. SIRS occurred after surgery is a risk factor for uterine contraction; on the contrary, no history of childbirth, shorter operation time, application of phloroglucinol, pain relief after surgery are protective factors.
