Abstract
OBJECTIVE In the treatment of uterine fibroids with ultrasound-guided high-intensity focused ultrasound (HIFU), water balloons are considered to be a valuable aid for improving safety and efficiency. However, the water balloons worsen the pathway for acoustic transmission, causing degraded performance both in ultrasound therapy and in ultrasound imaging. This study was aimed at establishing a protocol to evaluate the effects of the water balloon. METHODS Simulations and experiments were carefully conducted to quantitatively investigate the effects of water ballons on the efficiency of HIFU energy delivery and on the quality of ultrasound guiding images. More specifically, HIFU-induced temperature increases in the focal region, together with spatial resolution, contrast and signal-to-noise ratio in the ultrasound guiding images, were compared under the conditions with and without the water balloon. RESULTS Experiment results revealed that the use of water balloons led to decreases in temperature up to 10ºC within the focal region in some specific situations, but the quality of the guiding images was relatively less affected. CONCLUSION The study provided knowledge on what influence the water balloon could have in ultrasound-guided HIFU treatment; it also established a practical and standardized evaluation scheme for further optimizing the water balloon, for example, its material and internal liquid compositions. This study can potentially help improve the efficiency and safety of treating uterine fibroids with ultrasound-guided HIFU systems.

Abstract
A retrospective study was conducted on patients subjected to laparoscopic myomectomy at our institution from January 2017 to December 2018 to identify predictive factors of blood loss. Two multiple regression models were run to predict intraoperative blood loss and haemoglobin drop. Predictors of an increased intraoperative blood loss and haemoglobin drop were the presence of three-four fibroids at ultrasound (+47 ml, p = .01; +0.58 g/dl, p = .05) and increased operative time (r = 0.57, p = .01; r = 0.01, p < .01), while predictors of a reduced intraoperative blood loss and haemoglobin drop were epinephrine injection (-50 ml, p < .01; -0.42 g/dl, p < .01), FIGO7 (-87 ml, p < .01; -0.85, p = .01), and FIGO6 (-35 ml, p < .01; -0.44, p = .02) fibroids at the ultrasound. Preoperative ultrasound evaluation is crucial in identifying patients at higher risk for blood loss, which could benefit from optimising haemoglobin values. The injection of diluted epinephrine could be proposed in selected high-risk patients. In the clinical practice, a tailored approach based on fibroids' ultrasonographic characteristics should be implemented to optimise preoperative Hb values and evaluate the use of diluted epinephrine in selected cases, reducing blood loss and the potential related complications.Impact statementWhat is already known on this subject? Laparoscopic myomectomy is the conservative surgical treatment of choice for symptomatic uterine fibroids. Still, it could represent a challenging procedure even for an experienced surgeon, with the risk of excessive blood loss, need of transfusions, prolonged operative time, and prolonged hospital stay. The knowledge of the predictive factors of blood loss is essential for patient preparation and surgical planning to reduce intraoperative and postoperative complications.What do the results of this study add? The results of the present study focus on the importance of presurgical evaluation to identify predictive factors of intraoperative blood loss and Hb drop such as the number of fibroids and the FIGO classification (at preoperative ultrasound), as well as intraoperative factors like operative time and the intramyometrial injection of diluted epinephrine.What are the implications of these findings for clinical practice and/or further research? A tailored approach based on the ultrasonographic characteristics of fibroids should be implemented to optimise preoperative haemoblobin levels.

Abstract
Newer minimally invasive techniques provide treatment options for symptomatic uterine fibroids while allowing uterus preservation. The objective of this review was to analyze the efficacy of uterine-preserving, minimally invasive treatment modalities in reducing fibroid-related bleeding. A comprehensive search was conducted of PubMed, Embase, PsycINFO, ClinicalTrials.gov, Scopus, and Cochrane Library databases from inception to July 2020. English-language publications that evaluated premenopausal women with fibroid-related bleeding symptoms before and after treatment were considered. Randomized controlled trials were assessed for bias with the established Cochrane Risk of Bias Tool 2.0 and observational studies were assessed for quality under the New Castle-Ottawa Scale guidelines. Eighty-four studies were included in the review, including 10 randomized controlled trials and 74 observational studies. Six studies on myomectomy demonstrated overall bleeding symptom improvement in up to 95.9% of patients, though there was no significant difference between mode of myomectomy. Forty-one studies on uterine artery embolization reported significant reduction of fibroid-related bleeding, with symptomatic improvement in 79 to 98.5% of patients. Three studies suggested that embolization may be superior to myomectomy in reducing fibroid-related bleeding. Six studies reported that laparoscopic uterine artery occlusion combined with myomectomy led to greater reduction of bleeding than myomectomy alone. Fifteen studies demonstrated significantly reduced bleeding severity after radiofrequency ablation (RFA). Additional research is needed to establish the superiority of these modalities over one another. Long-term evidence is limited in current literature for magnetic resonance-guided focused ultrasound surgery, cryomyolysis, microwave ablation, and laser ablation.

Abstract
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.

Abstract
BACKGROUND Fibroids are the most common benign tumours of the female genital tract and are associated with numerous clinical problems including a possible negative impact on fertility. In women requesting preservation of fertility, fibroids can be surgically removed (myomectomy) by laparotomy, laparoscopically or hysteroscopically depending on the size, site and type of fibroid. Myomectomy is however a procedure that is not without risk and can result in serious complications. It is therefore essential to determine whether such a procedure can result in an improvement in fertility and, if so, to then determine the ideal surgical approach. OBJECTIVES To examine the effect of myomectomy on fertility outcomes and to compare different surgical approaches. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group (CGFG) Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Epistemonikos database, World Health Organization (WHO) International Clinical Trials Registry Platform search portal, Database of Abstracts of Reviews of Effects (DARE), LILACS, conference abstracts on the ISI Web of Knowledge, OpenSigle for grey literature from Europe, and reference list of relevant papers. The final search was in February 2019. SELECTION CRITERIA Randomised controlled trials (RCTs) examining the effect of myomectomy compared to no intervention or where different surgical approaches are compared regarding the effect on fertility outcomes in a group of infertile women suffering from uterine fibroids. DATA COLLECTION AND ANALYSIS Data collection and analysis were conducted in accordance with the procedure suggested in the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS This review included four RCTs with 442 participants. The evidence was very low-quality with the main limitations being due to serious imprecision, inconsistency and indirectness. Myomectomy versus no intervention One study examined the effect of myomectomy compared to no intervention on reproductive outcomes. We are uncertain whether myomectomy improves clinical pregnancy rate for intramural (odds ratio (OR) 1.88, 95% confidence interval (CI) 0.57 to 6.14; 45 participants; one study; very low-quality evidence), submucous (OR 2.04, 95% CI 0.62 to 6.66; 52 participants; one study; very low-quality evidence), intramural/subserous (OR 2.00, 95% CI 0.40 to 10.09; 31 participants; one study; very low-quality evidence) or intramural/submucous fibroids (OR 3.24, 95% CI 0.72 to 14.57; 42 participants; one study; very low-quality evidence). Similarly, we are uncertain whether myomectomy reduces miscarriage rate for intramural fibroids (OR 1.33, 95% CI 0.26 to 6.78; 45 participants; one study; very low-quality evidence), submucous fibroids (OR 1.27, 95% CI 0.27 to 5.97; 52 participants; one study; very low-quality evidence), intramural/subserous fibroids (OR 0.80, 95% CI 0.10 to 6.54; 31 participants; one study; very low-quality evidence) or intramural/submucous fibroids (OR 2.00, 95% CI 0.32 to 12.33; 42 participants; one study; very low-quality evidence). This study did not report on live birth, preterm delivery, ongoing pregnancy or caesarean section rate. Laparoscopic myomectomy versus myomectomy by laparotomy or mini-laparotomy Two studies compared laparoscopic myomectomy to myomectomy at laparotomy or mini-laparotomy. We are uncertain whether laparoscopic myomectomy compared to laparotomy or mini-laparotomy improves live birth rate (OR 0.80, 95% CI 0.42 to 1.50; 177 participants; two studies; I2 = 0%; very low-quality evidence), preterm delivery rate (OR 0.70, 95% CI 0.11 to 4.29; participants = 177; two studies; I2 = 0%, very low-quality evidence), clinical pregnancy rate (OR 0.96, 95% CI 0.52 to 1.78; 177 participants; two studies; I2 = 0%, very low-quality evidence), ongoing pregnancy rate (OR 1.61, 95% CI 0.26 to 10.04; 115 participants; one study; very low-quality evidence), miscarriage rate (OR 1.25, 95% CI 0.40 to 3.89; participants = 177; two studies; I2 = 0%, very low-quality evidence), or caesarean section rate (OR 0.69, 95% CI 0.34 to 1.39; participants = 177; two studies; I2 = 21%, very low-quality evidence). Monopolar resectoscope versus bipolar resectoscope One study evaluated the use of two electrosurgical systems during hysteroscopic myomectomy. We are uncertain whether bipolar resectoscope use compared to monopolar resectoscope use improves live birth/ongoing pregnancy rate (OR 0.86, 95% CI 0.30 to 2.50; 68 participants; one study, very low-quality evidence), clinical pregnancy rate (OR 0.88, 95% CI 0.33 to 2.36; 68 participants; one study; very low-quality evidence), or miscarriage rate (OR 1.00, 95% CI 0.19 to 5.34; participants = 68; one study; very low-quality evidence). This study did not report on preterm delivery or caesarean section rate. AUTHORS' CONCLUSIONS There is limited evidence to determine the role of myomectomy for infertility in women with fibroids as only one trial compared myomectomy with no myomectomy. If the decision is made to have a myomectomy, the current evidence does not indicate a superior method (laparoscopy, laparotomy or different electrosurgical systems) to improve rates of live birth, preterm delivery, clinical pregnancy, ongoing pregnancy, miscarriage, or caesarean section. Furthermore, the existing evidence needs to be viewed with caution due to the small number of events, minimal number of studies and very low-quality evidence.

Abstract
PURPOSE Laparoscopic myomectomy is the uterus-preserving surgical approach of choice in case of symptomatic fibroids. However, it can be a difficult procedure even for an experienced surgeon and can result in excessive blood loss, prolonged operating time and postoperative complications. A combined approach with laparoscopic uterine artery occlusion and simultaneous myomectomy was proposed to reduce these complications. The aim of this study was to evaluate the safety and efficacy of the combined laparoscopic approach in women with symptomatic "large" intramural uterine fibroids, compared to the traditional laparoscopic myomectomy alone. METHODS Prospective nonrandomized case-controlled study of women who underwent a conservative surgery for symptomatic "large" (≥ 5 cm in the largest diameter) intramural uterine fibroids. The "study group" consisted of women who underwent the combined approach (laparoscopic uterine artery bipolar coagulation and simultaneous myomectomy), while women who underwent the traditional laparoscopic myomectomy constituted the "control group". A comparison between the two groups was performed, and several intraoperative and postoperative outcomes were evaluated. RESULTS No significant difference in the overall duration of surgery between women of the "study group" and "control group" emerged; however, a significantly shorter surgical time for myomectomy was observed in the "study group". The intraoperative blood loss and the postoperative haemoglobin drop were significantly lower in the "study group". No difference in the postoperative pain between groups emerged, and the postoperative hospital stay was similar in the two groups. CONCLUSIONS The laparoscopic uterine artery bipolar coagulation and simultaneous myomectomy is a safe and effective procedure, even in women with symptomatic "large" intramural uterine fibroids, with the benefit of a significant reduction in the intraoperative blood loss when compared to the traditional laparoscopic myomectomy.

Abstract
UNLABELLED STUDY OBJECTIVE Intraligamental myomas (IMs) represent 6% to 10% of all uterine myomas. An IM growing from the lateral uterine wall into the broad ligament often presents as a large pelvic mass without symptoms. Removing a large IM can be difficult because of the limited operative field and poses challenges during conventional laparoscopic surgical approaches. The risk of injury to the ureter and uterine artery during myomectomy is greater than that during other types of myoma. DESIGN Retrospective study (Canadian Task Force classification III). SETTING University-affiliated hospital. PATIENTS IM was classified into 3 types according to the location: (1) anterior intraligamental myoma (AIM), (2) posterior intraligamental myoma (PIM), and (3) lateral intraligamental myoma (LIM). From April 2007 to July 2015, 83 consecutive patients with IM underwent laparoscopic myomectomy at National Taiwan University Hospital, Taipei, Taiwan, including 23 AIM, 27 PIM, and 33 LIM. INTERVENTIONS Several techniques are described, and videos are supplied for performing laparoscopic myomectomy safely and easily in different types of IM. MEASUREMENTS AND MAIN RESULTS Urinary frequency (31%) and a palpable abdominal mass (31%) were the 2 most common presenting symptoms. Most of the lesions were 33 LIM (40%) followed by 27 PIM (32%) and 23 AIM (28%). The mean myoma sizes were 11.0, 8.0, and 7.8 cm; the mean myoma weights were 478, 279, and 309 g; the mean operative times were 134, 108, and 104 minutes; and the mean blood loss during surgery was 224, 94, and 107 mL for LIM, PIM, and AIM, respectively. LIMs had relatively more blood loss because they were heavier and commonly rested alongside the uterine artery. The only complication was late postoperative hemorrhage in 1 case of LIM. Histopathology showed leiomyoma in all cases. Three patients were spontaneously conceived after myomectomy, and each had a successful pregnancy and cesarean delivery. CONCLUSION Surgical treatment of IM is empirically difficult. It is important to use an approach that considers the location, size, and shape of the myoma. All types of IM presented with similar symptoms, and the highest blood loss occurred during laparoscopic myomectomy of a LIM.

Abstract
BACKGROUND Benign smooth muscle tumours of the uterus, known as fibroids or myomas, are often symptomless. However, about one-third of women with fibroids will present with symptoms that are severe enough to warrant treatment. The standard treatment of symptomatic fibroids is hysterectomy (that is surgical removal of the uterus) for women who have completed childbearing, and myomectomy for women who desire future childbearing or simply want to preserve their uterus. Myomectomy, the surgical removal of myomas, can be associated with life-threatening bleeding. Excessive bleeding can necessitate emergency blood transfusion. Knowledge of the effectiveness of the interventions to reduce bleeding during myomectomy is essential to enable evidence-based clinical decisions. This is an update of the review published in The Cochrane Library (2011, Issue 11). OBJECTIVES To assess the effectiveness, safety, tolerability and costs of interventions to reduce blood loss during myomectomy. SEARCH METHODS In June 2014, we conducted electronic searches in the Cochrane Menstrual Disorders and Subfertility Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO, and trial registers for ongoing and registered trials. SELECTION CRITERIA We selected randomised controlled trials (RCTs) that compared potential interventions to reduce blood loss during myomectomy to placebo or no treatment. DATA COLLECTION AND ANALYSIS The two authors independently selected RCTs for inclusion, assessed the risk of bias and extracted data from the included RCTs. The primary review outcomes were blood loss and need for blood transfusion. We expressed study results as mean differences (MD) for continuous data and odds ratios for dichotomous data, with 95% confidence intervals (CI). We assessed the quality of evidence using GRADE methods. MAIN RESULTS Eighteen RCTs with 1250 participants met our inclusion criteria. The studies were conducted in hospital settings in low, middle and high income countries.Blood lossWe found significant reductions in blood loss with the following interventions: vaginal misoprostol (2 RCTs, 89 women: MD -97.88 ml, 95% CI -125.52 to -70.24; I(2) = 43%; moderate-quality evidence); intramyometrial vasopressin (3 RCTs, 128 women: MD -245.87 ml, 95% CI -434.58 to -57.16; I(2) = 98%; moderate-quality evidence); intramyometrial bupivacaine plus epinephrine (1 RCT, 60 women: MD -68.60 ml, 95% CI -93.69 to -43.51; low-quality evidence); intravenous tranexamic acid (1 RCT, 100 women: MD -243 ml, 95% CI -460.02 to -25.98; low-quality evidence); gelatin-thrombin matrix (1 RCT, 50 women: MD -545.00 ml, 95% CI -593.26 to -496.74; low-quality evidence); intravenous ascorbic acid (1 RCT, 102 women: MD -411.46 ml, 95% CI -502.58 to -320.34; low-quality evidence); vaginal dinoprostone (1 RCT, 108 women: MD -131.60 ml, 95% CI -253.42 to -9.78; low-quality evidence); loop ligation of the myoma pseudocapsule (1 RCT, 70 women: MD -305.01 ml, 95% CI -354.83 to -255.19; low-quality evidence); and a fibrin sealant patch (1 RCT, 70 women: MD -26.50 ml, 95% CI -44.47 to -8.53; low-quality evidence). We found evidence of significant reductions in blood loss with a polyglactin suture (1 RCT, 28 women: MD -1870.0 ml, 95% CI -2547.16 to 1192.84) or a Foley catheter (1 RCT, 93 women: MD -240.70 ml, 95% CI -359.61 to -121.79) tied around the cervix. However, pooling data from these peri-cervical tourniquet RCTs revealed significant heterogeneity of the effects (2 RCTs, 121 women: MD (random) -1019.85 ml, 95% CI -2615.02 to 575.32; I(2) = 95%; low-quality evidence). There was no good evidence of an effect on blood loss with oxytocin, morcellation or clipping of the uterine artery.Need for blood transfusion We found significant reductions in the need for blood transfusion with vasopressin (2 RCTs, 90 women: OR 0.15, 95% CI 0.03 to 0.74; I(2) = 0%; moderate-quality evidence); peri-cervical tourniquet (2 RCTs, 121 women: OR 0.09, 95% CI 0.01 to 0.84; I(2) = 69%; low-quality evidence); gelatin-thrombin matrix (1 RCT, 100 women: OR 0.01, 95% CI 0.00 to 0.10; low-quality evidence) and dinoprostone (1 RCT, 108 women: OR 0.17, 95% CI 0.04 to 0.81; low-quality evidence), but no evidence of effect on the need for blood transfusion with misoprostol, oxytocin, tranexamic acid, ascorbic acid, loop ligation of the myoma pseudocapsule and a fibrin sealant patch.There were insufficient data on the adverse effects and costs of the different interventions. AUTHORS' CONCLUSIONS At present there is moderate-quality evidence that misoprostol may reduce bleeding during myomectomy, and low-quality evidence that bupivacaine plus epinephrine, tranexamic acid, gelatin-thrombin matrix, a peri-cervical tourniquet, ascorbic acid, dinoprostone, loop ligation and a fibrin sealant patch may reduce bleeding during myomectomy. There is no evidence that oxytocin, morcellation and temporary clipping of the uterine artery reduce blood loss. Further well designed studies are required to establish the effectiveness, safety and costs of different interventions for reducing blood loss during myomectomy.

Abstract
BACKGROUND To determine whether performing transient occlusion of uterine arteries (TOUA) immediately before laparoscopic myomectomy can reduce intraoperative complications. SUBJECTS AND METHODS In a retrospective case-control study, laparoscopic myomectomy with and without TOUA was examined. Data were analyzed from 89 laparoscopic myomectomies performed by a single surgeon (Y.-S. Kwon) at Ulsan University Hospital (Ulsan, Korea) between March 2011 and December 2011. Surgical outcomes included preoperative myoma size, number of myoma, operative time, and operative blood loss. RESULTS Forty-nine women underwent laparoscopic myomectomy with TOUA with endoscopic vascular clipping, whereas 40 control patients underwent laparoscopic myomectomy alone. The TOUA group had no case of nerve or vascular injury during the operation time. The mean time of occlusion of both the uterine arteries was 15 minutes. The TOUA group had less mean blood loss during the operation than the group with laparoscopic myomectomy alone (111.9 versus 203.4 mL; P<.001). There were no significant differences in size and number of uterine myomas and intraoperative complications between the two groups. Moreover, there was not even a single case of conversion of laparoscopy to laparotomy in either group. CONCLUSIONS TOUA performed immediately before laparoscopic myomectomy facilitated minimally invasive surgery with lower blood loss and no differences in other intraoperative complications.

Abstract
BACKGROUND Fibroids are the most common benign tumours of the female genital tract and are associated with numerous clinical problems including a possible negative impact on fertility. In women requesting preservation of fertility, fibroids can be surgically removed (myomectomy) by laparotomy, laparoscopically or hysteroscopically depending on the size, site and type of fibroid. Myomectomy is however a procedure that is not without risk and can result in serious complications. It is therefore essential to determine whether such a procedure can result in an improvement in fertility and, if so, to then determine the ideal surgical approach. OBJECTIVES To examine the effect of myomectomy on fertility outcomes and to compare different surgical approaches. SEARCH METHODS We searched the Cochrane Menstrual Disorders and Subfertility Group (MDSG) Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL, Database of Abstracts of Reviews of Effects (DARE), LILACS, conference abstracts on the ISI Web of Knowledge, OpenSigle for grey literature from Europe, and ongoing clinical trials registered online. The final search was in June 2012. SELECTION CRITERIA Randomised controlled trials examining the effect of myomectomy compared to no intervention or where different surgical approaches are compared regarding the effect on fertility outcomes in a group of infertile women suffering from uterine fibroids. DATA COLLECTION AND ANALYSIS Data collection and analysis were conducted in accordance with the procedure suggested in the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS One study examined the effect of myomectomy on reproductive outcomes and showed no evidence for a significant effect on the clinical pregnancy rate for intramural (OR 1.88, 95% CI 0.57 to 6.14), submucous (OR 2.04, 95% CI 0.62 to 6.66), combined intramural and subserous (OR 2.00, 95% CI 0.40 to 10.09) and combined intramural submucous fibroids (OR 3.24, 95% CI 0.72 to 14.57). Similarly, there was no evidence for a significant effect of myomectomy for any of the described types of fibroids on the miscarriage rate (intramural fibroids OR 0.89 (95% CI 0.14 to 5.48), submucous fibroids OR 0.63 (95% CI 0.09 to 4.40), combined intramural and subserous fibroids OR 0.25 (95% CI 0.01 to 4.73) and combined intramural submucous fibroids OR 0.50 (95% CI 0.03 to 7.99).Two studies compared open versus laparoscopic myomectomy and found no evidence for a significant effect on the live birth rate (OR 0.80, 95% CI 0.42 to 1.50), clinical pregnancy rate (OR 0.96, 95% CI 0.52 to 1.78), ongoing pregnancy rate (OR 1.61, 95% CI 0.26 to 10.04), miscarriage rate (OR 1.31, 95% CI 0.40 to 4.27), preterm labour rate (OR 0.68, 95% CI 0.11 to 4.43) and caesarean section rate (OR 0.59, 95% CI 0.13 to 2.72). AUTHORS' CONCLUSIONS There is currently insufficient evidence from randomised controlled trials to evaluate the role of myomectomy to improve fertility. Regarding the surgical approach to myomectomy, current evidence from two randomised controlled trials suggests there is no significant difference between the laparoscopic and open approach regarding fertility performance. This evidence needs to be viewed with caution due to the small number of studies. Finally, there is currently no evidence from randomised controlled trials regarding the effect of hysteroscopic myomectomy on fertility outcomes.

Abstract
The uterine fibroid pseudocapsule is a fibro-neurovascular structure surrounding a leiomyoma, separating it from normal peripheral myometrium. The fibroid pseudocapsule is composed of a neurovascular network rich in neurofibers similar to the neurovascular bundle surrounding a prostate. The nerve-sparing radical prostatectomy has several intriguing parallels to myomectomy. It may serve either as a useful model in modern fibroid surgical removal, or it may accelerate our understanding of the role of the fibrovascular bundle and neurotransmitters in the healing and restoration of reproductive potential after intracapsular myomectomy. Surgical innovations, such as laparoscopic or robotic myomectomy applied to the intracapsular technique with magnification of the fibroid pseudocapsule surrounding a leiomyoma, originated from the radical prostatectomy method that highlighted a careful dissection of the neurovascular bundle to preserve sexual functioning after prostatectomy. Gentle uterine leiomyoma detachment from the pseudocapsule neurovascular bundle has allowed a reduction in uterine bleeding and uterine musculature trauma with sparing of the pseudocapsule neuropeptide fibers. This technique has had a favorable impact on functionality in reproduction and has improved fertility outcomes. Further research should determine the role of the myoma pseudocapsule neurovascular bundle in the formation, growth, and pathophysiological consequences of fibroids, including pain, infertility, and reproductive outcomes.
