“…As a noninvasive treatment technique, HIFU can be performed under the guidance of ultrasound (US-HIFU) or magnetic resonance imaging (MR-HIFU), so that the fibroids can be selectively ablated without damaging adjacent structures. This method requires minimal hospitalization, has no surgical wound, and has good relief and outcomes in many patients [67,68]. HIFU appears to be a safe and effective treatment in patients with uterine fibroids who wish to conceive and shows equivalent outcome in pregnancy rates compared to laparoscopic fibroid resection.…”

Uterine Fibroids and Infertility

Infertility is a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse. Uterine fibroids are the most common tumor in women, and their prevalence is high in patients with infertility. Fibroids may be the sole cause of infertility in 2–3% of women. Depending on their location in the uterus, fibroids have been implicated in recurrent pregnancy loss as well as infertility. Pregnancy and live birth rates appear to be low in women with submucosal fibroids; their resection has been shown to improve pregnancy rates. In contrast, subserosal fibroids do not affect fertility outcomes and their removal does not confer any benefit. Intramural fibroids appear to reduce fertility, but recommendations concerning their treatment remain unclear. Myomectomy should be discussed individually with the patient; other potential symptoms such as dysmenorrhea or bleeding disorders should be included in the indication for surgery.

“…In the 42/13 crude-oil operation room, the primary instrument on site is a three-wire vortex flowmeter, and the signal type is a frequency signal. The original design was to directly connect the data acquisition module to the signal end of the secondary meter [9]. Data can be collected, but after measurement, it is found that the signal has been attenuated by about half, so this wiring method is not advisable.…”

“…Park et al reported that in USgHIFU ablation of uterine fibroids, achievement of an immediate NPVR of at least 80% is safe, with greater tumor volume shrinkage compared with cases with a lower NPVR (19). A number of studies have shown that the average or median NPVR of USgHIFU ablation of uterine fibroids has reached more than 80% (9,21,22). One of the studies was from 20 centers, including 16 inexperienced centers.…”

Objective: To evaluate factors in predicting the treatment outcome of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation for uterine fibroids with a non-perfused volume ratio (NPVR) of at least 80%.Methods: One thousand patients with uterine fibroids who received USgHIFU were enrolled. Thirty-two independent variables of four dimensions of data set, including general information of patients, clinical symptoms, laboratory tests, and fibroid imaging characteristics, were used to investigate the potential predictors of the NPVR of at least 80% by multivariate logistic regression. NPVR was the gold standard for evaluating the efficiency of HIFU ablation, and a NPVR of at least 80% was considered sufficient ablation, while partial ablation was defined as having an NPVR of <80%.Results: Out of 1,000 fibroids, 758 obtained sufficient ablation and 242 obtained partial ablation, and the median NPVR was 88.3% (interquartile range: 80.3–94.8%). The probability of NPVR reaching 80% fibroids with a signal intensity of T2WI of hypointense, isointense, and hyperintense was 86.4, 76.5, and 62.6%, respectively; fibroids with an enhancement type of T1WI of slight, irregular, and regular was 81.5, 73.6, and 63.7%, respectively; and fibroids with uterine anteroposterior of 30–130 mm was 57.7–78.3%, respectively. In patients with a platelet count of 50 × 109/L−550 × 109/L, the probability of NPVR reaching 80% is from 53.4 to 80.1%, respectively.Conclusions: In predicting NPVR ≥ 80%, the signal intensity on T2WI was the most important factor affecting ablative efficiency, followed by enhancement type on T1WI, uterine anteroposterior, and platelet count.
