Pregnancy Outcomes After Direct Uterine Myoma Thermal Ablation: Review of the Literature

[Laparoscopic ultrasound-guided radiofrequency ablation of uterine fibroid: A retrospective study]

OBJECTIVE

To assess clinical and radiological efficacy and safety of laparoscopic ultrasound-guided radiofrequency ablation of uterine leiomyomas.

MATERIAL AND METHODS

Thirty-three patients with symptomatic uterine leiomyomas FIGO type 2 to 7, have undergone a laparoscopic ultrasound-guided radiofrequency ablation at Croix Rousse University Hospital Center (Hospices civils de Lyon) and at Saint-Vincent de Paul Hospital in Lille, between June 2020 and December 2022. The characteristics of each myoma and the symptoms were assessed with pelvic MRI and with Higham score, SSS and HRQL scores preoperatively and at 6 months.

RESULTS

A total of 54 fibroids have been treated in 33 patients. We observed a significant decrease of the volume 6 months after the surgery, on average 21mL (55.97 vs. 74.37mL, 95% CI [7.13-34.88], P=0.001). The maximum diameter of each fibroid was also significantly reduced on average 11.78mm (41.89 vs. 52.06, 95% CI [8.83-14.73], P<0.05). We noticed a significant decrease of the NRS for dysmenorrhea on average 2.79 points (2.1 vs. 4.89, 95% CI [1.14-4.42], P<0.05). There was also a trend to improvement of menorrhagia, assess by Higham score. Indeed, 70.8% of the patients had menorrhagia. Menorrhagia was improved of 108,3 points with an average Higham score before surgery of 197.3 versus 87.9 after surgery (95% CI [47.9-168.8], P=0.001). Concerning UFS-QOL score: the symptom severity score (SSS) decreased on average 33 points, testifying of symptom improvement (27.04 vs. 60.89, 95% CI [22.92-43.39], P<0.001) and the HRQL score increased on average 20 points testifying quality of life improvement (65.57 vs. 42.7, 95% CI [15.83-37.85]. P<0.001). No severe adverse event has been reported.

CONCLUSION

In this first French study about radiofrequency ablation. We confirm its efficiency for improvement of symptoms and quality of life but other study is mandatory to confirm the safety of this procedure in particular in patients with a wish to conceive.

Outcomes of transvaginal radiofrequency ablation for symptomatic leiomyomas

OBJECTIVE

Describe the effect of transvaginal radiofrequency ablation for leiomyoma in symptomatic patients and post procedure follow-up.

MATERIAL AND METHODS

A retrospective forward-looking observational study was performed including 63 patients who underwent transvaginal radiofrequency ablation between January 2016 and December 2022 at San Cecilio University Hospital in Granada, Spain. The variables registered were: age, parity, the clinical features that lead to the medical visit and pre-surgical treatment. Prior to the procedure, leiomyoma location and volume were determined by transvaginal ultrasound. Follow-ups were scheduled at 6 and 12 months to evaluate symptom improvement, adverse outcomes, leiomyoma volume and if any necessary post-surgical treatment was required.

RESULTS

Mean leiomyoma volume at baseline, 6 months and 12 months was 83.3 (24.9-130.7), 42.4 (4.7-89.0) and 19.2 (1.9-80.4) cm3, respectively (p < .001). Significant differences were found between the baseline and 12 month visits (p < .001). At the annual follow-up, the mean rate of volume reduction was 79.5 %, being higher in women who reported symptom improvement compared to those who reported no change in symptom intensity from baseline (84.6% vs. 30.8 %). Patients with a lower initial volume and age over 40 were more likely to have treatment efficacy. 8 pregnancies were registered post procedure.

CONCLUSION

Radiofrequency is well tolerated, allowing for same-day discharge, rapid recovery and a safe approach for women who want to preserve their reproductive potential. Initial volume and age over 40 appear to be factors that should be considered in patient selection. Further studies are needed to continue evaluating the outcomes and identifying predictive factors.

Transcervical Fibroid Ablation (TFA): Update on Pregnancy Outcomes

Background/Objectives: Transcervical fibroid ablation (TFA) is an incisionless method to treat symptomatic uterine fibroids. While safety regarding future pregnancy remains to be established, TFA does not preclude the possibility of pregnancy, and a previous 36-patient case series of post-TFA pregnancies reported normal outcomes. That prior series did not include postmarket cases in the United States, as the Sonata® System was initially cleared and used in Europe. This is a substantive update of known pregnancies with the Sonata System since June 2011, and includes pregnancies in Europe, Mexico, and the US. Methods: TFA was carried out under both clinical trial and postmarket use to treat symptomatic uterine fibroids. All post-TFA pregnancies reported by physicians with their patient's consent were included. Results: 89 pregnancies and 55 deliveries have occurred among 72 women treated with the Sonata System. This includes 8 women who conceived more than once after TFA. Completed pregnancies (n = 62 women) include 19 vaginal deliveries, 35 Cesarean sections, 5 therapeutic abortions, 1 ectopic pregnancy, and 1 delivery by an unknown route. Ten pregnancies are ongoing. Mean birthweight was 3276.7 ± 587.3 g. Ten women experienced 18 first-trimester spontaneous abortions (SAbs), with 10 of the 18 SAbs (55.6%) occurring between two patients with a history of recurrent abortion. The SAb rate was 22.8%, inclusive of these two patients, and 10.1% if they were excluded as outliers. There were no instances of uterine rupture, placenta accreta spectrum, or stillbirth. Conclusions: This case series, the largest to date for any hyperthermic ablation modality, suggests that TFA with the Sonata System could be a feasible, safe treatment option regarding eventual pregnancy in women with symptomatic uterine fibroids.

Radiofrequency Ablation of Uterine Fibroids and Pregnancy Outcomes: An Updated Review of the Literature

OBJECTIVE

To provide a systematic review of pregnancy outcomes after radiofrequency ablation of uterine fibroids.

DATA SOURCES

A literature search was conducted using PubMed, Cochrane Library, Scopus, Web of Science, and EMBASE, from database inception until October 2021.

METHODS OF STUDY SELECTION

Two reviewers conducted independent literature searches. Studies that met criteria based on title and abstract underwent full text review. Publications were included if they reported pregnancies and obstetric outcomes after laparoscopic or transcervical radiofrequency ablation (RFA) of fibroids.

TABULATION, INTEGRATION, AND RESULTS

405 publications were initially identified and screened, 39 underwent full text review, and 10 publications were ultimately included. There were 50 pregnancies reported among 923 RFA patients: 40 pregnancies after 559 laparoscopic RFAs and 10 pregnancies after 364 transcervical RFAs. The number of patients from these studies actively trying to conceive after RFA is unknown. Among the RFA patients who conceived, the average age at ablation was 37 years old (range 27 to 46 years). The majority of patients had between 1 and 3 fibroids ablated, and fibroid size ranged from less than 2 centimeters to 12.5 centimeters. There were 6 spontaneous abortions (12%) and 44 full-term pregnancies (88%), of which 24 were vaginal deliveries and 20 were cesarean deliveries. There were only 2 complications among 44 deliveries: 1 placenta previa that underwent an uncomplicated cesarean delivery and 1 delayed postpartum hemorrhage with expulsion of a degenerated myoma, with no long-term sequelae. There were no cases of uterine rupture, uterine window, or invasive placentation, and no fetal complications. The spontaneous abortion rate was comparable to the general obstetric population.

CONCLUSION

Almost all pregnancies after radiofrequency ablation of fibroids were full-term deliveries with no maternal or neonatal complications. These findings add to the literature that radiofrequency fibroid ablation may offer a safe and effective alternative to existing treatments for women who desire future fertility.

Analysis of high intensity focused ultrasound in treatment of uterine fibroids on ovarian function and pregnancy outcome

AIM

To investigate the ovarian function and pregnancy outcome of patients with uterine fibroids and the influencing factors after high intensity focused ultrasound (HIFU) ablation treatment.

METHODS

A total of 80 patients were recruited. All patients were divided into the pregnancy group (64 cases) and the non-pregnancy group (16 cases). The pregnancy group was categorized into the good pregnancy outcome (GOP) group (46 cases) and adverse pregnancy outcome (APO) group (18 cases). The general data of all study subjects were collected. The changes of anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), inhibin B (INHB), and antral follicle count (AFC) before HIFU and 3, 6, and 12 months after HIFU were compared. The related factors affecting pregnancy and pregnancy outcomes were analyzed.

RESULTS

There were no significant differences in AMH, FSH, INHB levels, and AFC at 6 and 12 months after HIFU compared with those before HIFU in pregnancy and non-pregnancy groups (p > 0.05). This study demonstrated that patients with prior history of pregnancy, younger age, lower body mass index (BMI), and smaller fibroids volume had a higher pregnancy rate (p < 0.05). Besides, younger age and smaller fibroids volume were associated with better pregnancy outcomes (p < 0.05).

CONCLUSIONS

HIFU in the treatment of uterine fibroids has little effect on ovarian function and does not increase the risk of infertility and adverse pregnancy. The prior history of pregnancy, age, BMI, and fibroids volume are essential factors affecting the postoperative pregnancy.

Pregnancy Outcomes After Transcervical Radiofrequency Ablation of Uterine Fibroids with the Sonata System

Objective:

To describe pregnancy outcomes in women who conceived after undergoing transcervical fibroid ablation (TFA) as treatment for symptomatic uterine fibroids.

Materials and Methods:

TFA was used to treat symptomatic uterine fibroids with radiofrequency energy, both under clinical trial protocol and commercial usage in hospitals in Europe, the United Kingdom, Mexico, and the United States. All women who reported pregnancies to their physicians after undergoing TFA with the Sonata^® System and provided consent for use of their data were included.

Results:

There have been 36 pregnancies representing 20 deliveries among 28 women who were treated with TFA. Five women conceived more than once postablation, and four conceived as a result of assisted reproductive technology (ART). Outcomes include 8 vaginal deliveries, 12 Cesarean sections, 3 therapeutic abortions, and 8 first trimester spontaneous abortions (four occurring in a patient with a history of recurrent pregnancy loss and an immunologic disorder). Five women are currently pregnant, two of whom previously delivered after TFA. There were no 5-minute Apgar scores <7, and all neonates weighed >2500 g. All deliveries occurred at ≥37 weeks except for one delivery at 35 6/7 weeks. There were no uterine ruptures or abnormal placentation and no reports of postpartum hemorrhage or stillbirths. Ablated fibroids included transmural, submucous, and intramural myomata up to 7 cm in diameter.

Conclusions:

Normal pregnancy outcomes at term have occurred after TFA with the Sonata System, including in women with recurrent abortion and in those undergoing ART. There were no instances of low Apgar scores, low birthweight, stillbirth, postpartum hemorrhage, or uterine rupture (FAST-EU, NCT01226290; SONATA, NCT02228174; SAGE, NCT03 118037).

The role of anti-proliferative effects of atorvastatin on uterine fibroids: findings from a clinical study

AIM

Uterine myomas/fibroids are one of the most common benign tumors of the reproductive system in women. Given pleiotropic effects of statins, the aim of this study is to evaluate the therapeutic effects of atorvastatin on uterine fibroids in women of reproductive age.

MATERIALS AND METHODS

This randomized clinical study included 90 women aged 35-45 years with uterine fibroids. The patients were randomly allocated into the intervention group (received one tablet, 20 mg of atorvastatin every day for three months) and placebo. Ultrasound was performed every month, and the change in the size of fibroids was recorded for each patient. At the end of the study, the data obtained were analyzed using SPSSv22 and a p value < .05 was considered statistically significant.

RESULTS

The mean age in the placebo and intervention group was 39.63 ± 36.3 and 40.35 ± 3.32 years, respectively. The number and location of the tumor was comparable for the two groups. We observed a statically significant reduction in fibroid size from the treatment initiation until completion of three months, (41.06 ± 6.68 mm³ vs 35.16 ± 6.67 mm³) p = .0001. However, the decrease in fibroid size from 1st month to the 3rd month was not statistically significant, p = .189 (36.71 ± 5.54 mm³ vs 35.16 ± 6.67 mm³).

CONCLUSION

This study shows that treatment with atorvastatin might positively reduce the size of fibroids. The decrease was only statistically significant during the first month. Further studies with a detailed analysis of the intervention's clinical impact are required to consider statins as a therapeutic tool.

Comparison of magnetic resonance-guided high-intensity focused ultrasound with uterine artery embolization for the treatment of uterine myoma: A systematic literature review and meta-analysis

OBJECTIVE

This study aimed to compare the outcomes of magnetic resonance-guided (MR-g) high-intensity focused ultrasound (HIFU) with uterine artery embolization (UAE) for the treatment of uterine myoma.

MATERIALS AND METHODS

A systematic literature review and meta-analysis was conducted using database searches of Medline, Cochrane, EMBASE, and Google Scholar. Articles were searched through March 25, 2020. Outcomes of interest were Symptom Severity Score (SSS), Health-related Quality of Life (HRQoL), re-intervention rate, and rate of adverse reactions in patients with uterine myoma.

RESULTS

Four studies were included with a total of 207 patients with uterine myomas who received MR-g HIFU and 201 who received UAE. UAE was associated with a greater reduction in SSS, improved HRQoL, and a significantly lower re-intervention rate compared with MR-g HIFU in 3 of 4 included studies. No significant differences were found in the incidence and severity of adverse events between treatment arms in one study, but differences were observed in the percentage of adverse reactions in another.

CONCLUSION

Published evidence suggests that the efficacy of MR-g HIFU may not be superior to that of UAE in the treatment of uterine myoma.

A comparison of the pregnancy outcomes between ultrasound-guided high-intensity focused ultrasound ablation and laparoscopic myomectomy for uterine fibroids: a comparative study

Objective: To compare the pregnancy outcomes between ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation and laparoscopic myomectomy (LM).Materials and methods: This study included 676 women with symptomatic uterine fibroids who wished to become pregnant underwent USgHIFU or LM at three hospitals in China from 1 May 2009 to 31 May 2018. The related information of pregnancy and delivery were followed up and analyzed using the chi-square test and two-sided Student t-test.Results: The median follow-up duration was 5 (1-8) years; 20 patients (2.9%) were lost to follow-up. 320 patients were treated with UsgHIFU, and 336 were treated with LM. Two hundred nineteen (68.4%) women became pregnant after USgHIFU ablation, and 224 (66.7%) became pregnant after LM. Four hundred forty-three patients had 501 pregnancies (natural pregnancies, 405; in vitro fertilisation-embryo transfer pregnancies, 38). Average times to pregnancy were 13.6 ± 9.5 months after USgHIFU and 18.9 ± 7.3 months after LM (p < 0.05). The rate of cesarean delivery was lower in the USgHIFU group (41.6%) than in the LM group (54.9%) (p < 0.05). Incidences of placenta increta, placenta previa, and postpartum hemorrhage were low after USgHIFU compared with after LM. Incidences of preterm birth, fetal distress, fetal growth restriction, and puerperal infection were higher after USgHIFU than after LM. There was a risk of uterine rupture after both procedures.Conclusions: Compared with LM, USgHIFU ablation can significantly shorten the time to pregnancy, although pregnancy rates of the two procedures are similar. Some risks in pregnancy and delivery after HIFU should be evaluated and monitored.

Systematic review of reproductive outcomes after High Intensity Focused Ultrasound treatment of uterine fibroids

PURPOSE

Myomectomy is currently the gold standard for the treatment of uterine fibroids in women who desire pregnancy. However, this surgical fibroid removal has a long convalescence. Promising alternatives may be non-invasive High Intensity Focused Ultrasound (HIFU) under either MRI (MR-HIFU) or ultrasound guidance (USgHIFU). In this systematic review, an overview is provided of reproductive outcomes after these two relatively new ablation techniques.

METHOD

A systematic literature search was performed to identify studies reporting reproductive outcomes after HIFU treatment of fibroids. Only peer reviewed, full papers were included. Outcomes included pregnancy-, live-birth- miscarriage and caesarian section rate, time to conceive, reported complications, and possible prognostic factors.

RESULTS

In total 21 studies were included. Fourteen studies reported 124 pregnancies after MR-HIFU. Two placenta previas and no uterus ruptures were reported. Pregnancy rates were only retrospectively collected and ranged between 7% and 36%. Miscarriage rate in the oldest and largest prospective registry was 39%. After USgHIFU 366 pregnancies were reported with one fetal intrauterine death, six placenta previas and no uterus ruptures. The only prospective study reported a pregnancy rate of 47% and a miscarriage rate of 11%. Possible prognostic factors like age were not available in most studies.

CONCLUSIONS

Based on the heterogeneous data currently available, reproductive outcomes after HIFU appear non-inferior to outcomes after the current standard of care. However, a (randomized) controlled trial comparing reproductive outcomes after HIFU and standard care is necessary to provide sufficient evidence on the preferred fibroid treatment for women with a pregnancy wish.

A Systematic Review of the Treatment of Uterine Myomas Using Transcervical Ultrasound-Guided Radiofrequency Ablation with the Sonata System

OBJECTIVE

To evaluate the treatment success, possible side effects, and safety of radiofrequency ablation with the Sonata System.

DATA SOURCES

An electronic literature search in the PubMed and Medline databases was carried out from inception to August 2020.

METHODS OF STUDY SELECTION

The review was performed in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Keywords such as "Sonata," "transcervical ablation," and "uterine myoma" were used to identify all relevant articles independently by both authors. Full-text articles in English that reported at least 1 of the following outcomes were included in the study: reduction in perfused/total myoma volume, effect of treatment on bleeding intensity and myoma-related symptoms, number of surgical reinterventions, adverse events, return to activities of daily life, effects on surrounding tissue, and safety during pregnancy.

TABULATION, INTEGRATION, AND RESULTS

10 studies matching the inclusion criteria were identified and used for further analysis. A reduction in total and perfused myoma volume of 63.2% and 64.5% was achieved. One of the studies showed a 53.8 ± 50.5% (n = 48) reduction in Menstrual Pictogram Score, and another study showed a 51.1 ± 40.9% (n = 142) reduction in Pictorial Blood Loss Assessment Chart at 12 months. 87.2% (n = 190) of the patients reported a clinically meaningful reduction in menstrual blood loss after 12 months. While Symptom Severity Scores dropped by 28.8 ± 19.3, 23.3 ± 23.7, and 23.7 ± 19.4 points at 3, 6, and 12 months, respectively, Health-Related Quality of Life Scores increased to 77.5 ± 22.0, 82.8 ± 19.0, and 83.3 ± 20.5 points. One study had an 8% reintervention rate after 12 months, and another study showed a 0.7% and 5.2% rate after 12 and 24 months. After an average of 64 months after ablation, the reintervention rate was 11.8%. Time to return to activities of daily life was 2.9 ± 2.5 days. No related complications during pregnancy and delivery were reported.

CONCLUSION

Radiofrequency ablation with the Sonata System represents a minimally invasive, organ-preserving treatment option in patients with symptomatic uterine myomas, associated with clinically meaningful improvement of myoma-related symptoms.

The INTEGRITY Trial: Preservation of Uterine-Wall Integrity 12 Months After Transcervical Fibroid Ablation with the Sonata System

Objective: The aim of this research was to evaluate uterine-wall integrity 12 months after transcervical fibroid ablation (TFA) of uterine fibroids with the Sonata^® system (Gynesonics Inc., Redwood City, CA).

Materials and Methods: INTEGRITY is a secondary analysis of the FAST-EU clinical trial, a prospective, longitudinal, multicenter single-armed trial involving women with heavy menstrual bleeding secondary to fibroids who were treated at 7 academic and community hospitals in the United Kingdom, the Netherlands, and Mexico with transcervical, intrauterine, ultrasound-guided radiofrequency ablation (the Sonata system). TFA was performed on up to 5 fibroids per subject ranging from 1–5 cm in diameter as determined by magnetic resonance imaging (MRI). All measurements and comparisons, including uterine-wall thicknesses were derived from baseline and 12-month MRI scans by an independent core MRI center. Scans were analyzed to assess preservation of uterine-wall integrity and reviewed for uterine-wall anomalies after TFA with the Sonata system.

Results: Twenty-nine patients had baseline and 12-month MRI with contrast enhancement. Minimum uterine-wall thicknesses in all visible slices were >2.5 mm in diameter. No areas on MRI indicated any loss of uterine-wall integrity, compared with baseline imaging; comparison of baseline and postablation uterine-wall thicknesses revealed no significant changes.

Conclusion: Transcervical fibroid ablation with the Sonata system was associated with preservation of uterine-wall integrity in this patient cohort.

Uterine polyps, adenomyosis, leiomyomas, and endometrial receptivity

Endometrial polyps, adenomyosis, and leiomyomas are commonly encountered abnormalities frequently found in both fertile women and those with infertility. The clinician is frequently challenged to determine which of these entities, when found, is likely to impair fertility, and which are "innocent bystanders" unrelated to the problem at hand. Although removing an endometrial polyp may be seen as a relatively benign and safe intervention, myomectomy, and in particular adenomyomectomy, can be substantive surgical procedures, associated with their own potential for disrupting fertility. One of the mechanisms thought to be involved when these entities are contributing to infertility is an adverse impact on endometrial receptivity. Indeed polyps, adenomyosis, and leiomyomas have all been associated with an increased likelihood of abnormal endometrial molecular expressions thought to impair implantation and early embryo development. This review is designed to examine the relationship of these common entities to endometrial receptivity and to identify evidence gaps that should be considered when strategizing research initiatives. It is apparent that we have the tools necessary to fill these gaps, but it will be necessary to approach the issue in a strategic and coordinated fashion. It is likely that we will have to recognize the limitations of imaging alone and look to the evidence-based addition of molecular analysis to provide the individualized phenotyping of disease necessary for patient-specific treatment decisions.

Term Delivery in an Infertile Patient after Transcervical Radiofrequency Fibroid Ablation and Assisted Reproductive Technology

Background: Transcervical radiofrequency (RF) ablation of uterine fibroids is an incisionless procedure to treat nonpedunculated uterine fibroids, including those that are not amenable to operative hysteroscopy. However, its safety and effectiveness regarding fertility and fecundity have not been established, including among women with infertility. Case: A 38-year-old nullipara with infertility since 2008 and a recent complaint of refractory dysmenorrhea in association with a uterine fibroid underwent transcervical RF ablation with the Sonata^® System (Gynesonics, Redwood City, CA) to treat the symptomatic myoma. Unsuccessful assisted reproduction (intracytoplasmic sperm injection/embryo transfer) as confirmed by negative pregnancy testing had been attempted 1 month preablation, and a second embryo transfer after thawing the previously cryopreserved pronuclei was performed 7 months postablation. Results: RF ablation with the Sonata System resulted in a 68% reduction in fibroid volume noted on sonography 2 months post-treatment along with resolution of the patient's dysmenorrhea. No residual fibroid was noted on sonography 7 months postablation. A second attempt at assisted reproduction produced an uncomplicated pregnancy that resulted in vacuum-assisted vaginal delivery of a liveborn infant at term weighing 3670 g with Apgar scores of 9¹/10⁵/10¹⁰. Pelvic sonography 4 months postpartum an unremarkable uterus, again, with no evidence of a fibroid remnant. Conclusions: This is the first report of a pregnancy and delivery in an infertile couple who underwent transcervical RF ablation of a uterine fibroid followed by assisted reproduction.

Long-Term Clinical Outcomes of Transcervical Radiofrequency Ablation of Uterine Fibroids: The VITALITY Study

Objective: The aim of this research was to learn the long-term (> 5 years) clinical outcomes of transcervical radiofrequency ablation of uterine fibroids.

Materials and Methods: For this retrospective, single-arm, long-term data-collection study, 23 women with heavy menstrual bleeding secondary to fibroids were treated with transcervical radiofrequency ablation guided by integrated intrauterine sonography (using the Sonata^® System, Gynesonics, Redwood City, CA). This study was within the 12-month Fibroid Ablation Study-EU clinical trial in Mexico. Symptoms were assessed using the Uterine Fibroid Symptom and Quality-of-Life's Symptom Severity Score (SSS) and Health-Related Quality of Life (HRQoL) subscales. Patients were queried regarding pregnancy and surgical reinterventions.

Results: Seventeen women (73.9%) provided long-term follow-up information, with a mean of 64.4 months ±4.5 months (range: 57–73 months). From baseline, mean SSS decreased significantly from 64.9 ± 16.9 to 27.6 ± 36.1, and mean HRQoL improved significantly from 27.2 ± 22.4 to 76.0 ± 32.6 (p = 0.002, and p = 0.0001, respectively). There were no surgical reinterventions through the first 3.5 years post-treatment. There was an 11.8% incidence of surgical reinterventions over 5.4 years of average follow-up, with 2 hysterectomies occurring after 3.5 and 4 years postablation, respectively (event rate: 2.2% per year; 95% confidence interval; 0.3%, 7.9%). Freedom from surgical reintervention at 1, 2, and 3 years was 100%, and, at 4 and 5 years, was 88.2% ± 7.8%. There was a single pregnancy occurring within the first year of treatment leading to a normal-term delivery by elective repeat cesarean section.

Conclusions: Transcervical radiofrequency ablation with the Sonata System produced substantial durable clinical benefits beyond 5 years with a low reintervention rate.

Nonresective treatments for uterine fibroids: a systematic review of uterine and fibroid volume reductions

Patients are increasingly seeking uterus-preserving, minimally invasive treatments for symptomatic uterine fibroids. This has led to a greater use of nonresective treatments such as uterine artery embolization (UAE), focused ultrasound (FUS) and more recently, radiofrequency ablation (RFA) of fibroids. This systematic review, following PRISMA guidelines, examines the change in uterine and fibroid volumes associated with UAE, FUS, and RFA. Pubmed and MedlinePlus databases were searched from 1956 to 2016. The keywords used were 'radiofrequency ablation,' 'magnetic resonance guided focused ultrasound,' 'ultrasound guided focused ultrasound', 'uterine artery embolization,' 'uterine fibroid embolization,' and 'leiomyoma' or 'fibroid'. Publications with at least 20 patients were included. Data were collected and analyzed using Microsoft Excel^® (Microsoft Corporation, Redmond, WA) software. Eighty-one relevant papers were identified: 52 related to UAE, 11 to RFA, 17 to FUS, 1 compared UAE and FUS. We report the published uterine volume and fibroid volume changes seen in these studies at 1 to 36 months. The pooled fibroid volume reductions at six months seen with RFA were 70%, UAE 54% and FUS 32%. All three types of nonresective treatment result in fibroid volume reduction. However, fibroid volume reduction is most marked with RFA, with UAE resulting in the next most volume reduction. Additional larger cohort studies, including those that are randomized and/or comparative, would enable definitive conclusions. This is the first systematic review comparing uterine and fibroid volume reduction after RFA, UAE and MRgFUS.

Normal spontaneous vaginal delivery after transcervical radiofrequency ablation of uterine fibroids: a case report

Transcervical radiofrequency ablation of uterine fibroids was performed on a patient in Germany, who subsequently conceived. This is the first report of a normal spontaneous vaginal delivery after fibroid ablation with the Sonata^® System.

Alternatives to excisional therapy: a clinical review of our current options to conservatively manage symptomatic leiomyomas

PURPOSE OF REVIEW

This article provides a clinical review of the alternatives to traditional excisional surgical therapies for uterine leiomyomas, such as myomectomy or hysterectomy.

RECENT FINDINGS

In this review, currently available hormonal medications will be briefly discussed. Then, nonhormonal medical therapy will be addressed with respect to mechanism of action, safety, and efficacy. Finally, the risk-benefit profile of nonexcisional procedures for management of leiomyomas will be addressed.

SUMMARY

This provides an update on the information available for more conservative options for symptomatic leiomyoma management.

Non-surgical Management of Myomas

Uterine myomas are a common condition and the leading cause of hysterectomy. Clinically, myomas can be challenging because they range from asymptomatic to causing severe, debilitating symptoms and occur in many women before childbearing is complete. Thus, women often seek uterine-conserving and nonsurgical management of their myomas. In this review the available uterine-conserving treatment options from medical management through minimally invasive procedures are discussed. To the extent of research available, the sustainability of symptom improvement and the effects on future fertility are reviewed. Future research may lead to therapies that reduce the risks of major surgery, decrease side effects, and offer primary or secondary prevention options.
