Changes in Pelvic Floor Symptoms After Procedural Interventions for Uterine Leiomyomas: A Systematic Review. Obstet Gynecol 2023; 142:319-329. [PMID: 37411023 DOI: 10.1097/aog.0000000000005260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 05/11/2023] [Indexed: 07/08/2023]
Abstract
OBJECTIVE To conduct a systematic review to evaluate the effect of procedural interventions for leiomyomas on pelvic floor symptoms. DATA SOURCES PubMed, EMBASE, and ClinicalTrials.gov were searched from inception to January 12, 2023, searching for leiomyoma procedures and pelvic floor disorders and symptoms, restricted to primary study designs in humans. METHODS OF STUDY SELECTION Double independent screening for studies of any study design in all languages that reported pelvic floor symptoms before and after surgical (hysterectomy, myomectomy, radiofrequency volumetric thermal ablation) or radiologic (uterine artery embolization, magnetic resonance-guided focused ultrasonography, high-intensity focused ultrasonography) procedures for management of uterine leiomyomas. Data were extracted, with risk-of-bias assessment and review by a second researcher. Random effects model meta-analyses were conducted, as feasible. TABULATION, INTEGRATION, AND RESULTS Six randomized controlled trials, one nonrandomized comparative study, and 25 single-group studies met criteria. The overall quality of the studies was moderate. Only six studies, reporting various outcomes, directly compared two procedures for leiomyomas. Across studies, leiomyoma procedures were associated with decreased symptom distress per the UDI-6 (Urinary Distress Inventory, Short Form) (summary mean change -18.7, 95% CI -25.9 to -11.5; six studies) and improved quality of life per the IIQ-7 (Incontinence Impact Questionnaire, Short Form) (summary mean change -10.7, 95% CI -15.8 to -5.6; six studies). There was a wide range of resolution of urinary symptoms after procedural interventions (7.6-100%), and this varied over time. Urinary symptoms improved in 19.0-87.5% of patients, and the definitions for improvement varied between studies. Bowel symptoms were inconsistently reported in the literature. CONCLUSION Urinary symptoms improved after procedural interventions for uterine leiomyomas, although there is high heterogeneity among studies and few data on long-term outcomes or comparing different procedures. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42021272678.

Thermo-sensitive composite hydrogels based on poloxamer 407 and alginate and their therapeutic effect in embolization in rabbit VX2 liver tumors. Oncotarget 2018; 7:73280-73291. [PMID: 27602579 PMCID: PMC5341979 DOI: 10.18632/oncotarget.11789] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Accepted: 08/25/2016] [Indexed: 12/11/2022] Open
Abstract
Interventional embolization therapy is an effective, most widely used method for inoperable liver tumors. Blood-vessel-embolic agents were essential in transarterial embolization (TAE). In this work, thermo-sensitive composite hydrogels based on poloxamer 407, sodium alginate, hydroxymethyl cellulose and iodixanol (PSHI), together with Ca2+ (PSHI-Ca2+) were prepared as liquid embolic agents for TAE therapy to liver cancer. With increasing temperature, PSHI exhibited two phase states: a flowing sol and a shrunken gel. Rheology tests showed good fluidity and excellent viscoelastic behavior with a gelation temperature (GT) of 26.5°C. The studies of erosion indicated that PSHI had calcium ion-related erosion characteristics and showed a slow erosion rate in an aqueous environment. When incubated with L929 cells, the thermo-sensitive composite hydrogels had low cytotoxicity in vitro. The results of analyzing the digital subtraction angiography and computed tomography images obtained from in vitro and in vivo assays indicated a good embolic effect in the renal arteries of normal rabbits. Angiography and histological studies on VX2 tumor-bearing rabbits indicated that PSHI-Ca2+ successfully occluded the tumors, including the peripheral vessels. In conclusion, PSHI-Ca2+ was a promising embolic agent for transarterial embolization therapy.

Abstract
Background: Uterine artery embolization (UAE) is one of the minimally-invasive alternatives to hysterectomy for treatment of uterine leiomyomas. There are various factors affecting the outcomes of UAE, but these have only been sporadically studied. Study Objective: To identify factors associated with the efficacy of UAE for the treatment of uterine leiomyoma, and to develop a model for the prediction of treatment response of uterine leiomyomas to UAE. Study design: A retrospective cohort study (Canadian Task Force Classification II-2) Patients: One hundred ninety-eight patients with symptomatic uterine leiomyomas. Intervention: UAE Measurements and Main Results: Among 198 leiomyoma patients who were treated with UAE, 104 who underwent pelvic magnetic resonance imaging (MRI) with diffusion-weighted imaging were selected for developing prediction model. Variables that were statistically significant from the univariate analysis were: location of leiomyoma, total number of lesions, sum of leiomyomas diameters, T2 signal intensity of largest leiomyoma, and T2 leiomyoma:muscle ratio. After a logistic regression analysis, leiomyoma location and T2 signal intensity of the largest leiomyoma were found to be statistically significant variables. Using intramural myomas defined as controls, submucosal leiomyomas showed a greater response to UAE with an odds ratio of 7.6904. The odds ratio of T2 signal intensity with an increase in signal intensity of 10 was 1.093. Using these two variables, we developed a prediction model. The AUC in the prediction model was 0.833, and the AUC in the validation set was 0.791. Conclusion: We identified that submucosal leiomyomas and those leiomyomas that show high signal intensity on T2-weighted imaging will exhibit a greater response to UAE. Prediction models are clinically helpful in selecting UAE as an appropriate treatment option for managing uterine leiomyoma.

Treatment failure after uterine artery embolization: prospective cohort study with multifactorial analysis of possible predictors of long-term outcome. Eur J Radiol 2012; 81:e727-31. [PMID: 22381440 DOI: 10.1016/j.ejrad.2012.01.031] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2011] [Revised: 01/15/2012] [Accepted: 01/18/2012] [Indexed: 11/23/2022]
Abstract
PURPOSE To evaluate the impact of baseline characteristics and residual leiomyoma perfusion after uterine artery embolization (UAE) on clinical long-term outcome. MATERIALS AND METHODS One hundred fifteen patients underwent UAE. All patients were divided into three groups according to achieved infarction rate determined on contrast-enhanced magnetic resonance imaging within 48-72 h after UAE (I: 100%, n=60; II: 90-99%, n=32; and III: 0-89%, n=23). Treatment failure and subsequent re-interventions (surgery, repeat UAE) were assessed for each group and compared using Cox regression analysis (CRA) with respect to the following baseline variables: age, uterine and dominant fibroid volume, number of fibroids, location of largest fibroid, and clinical symptoms. RESULTS Long-term follow-up was completed after a median of 7.2 years (range 5.1-9.6) with a response rate of 84%. CRA revealed that patients in group III had a 22.2-fold higher risk (p<0.001) of treatment failure than patients in group I, whereas groups I and II did not differ significantly (p=0.578). For patients with bleeding-related symptoms only, CRA showed a 5.1-fold higher risk (p=0.025) of treatment failure than for patients with equally dominant bleeding- and bulk-related symptoms. A 40.5-fold higher likelihood (p<0.001) of treatment failure was observed for patients in group III with bleeding-related symptoms only compared to those in group I with combined bleeding- and bulk-related symptoms. CONCLUSION Incomplete fibroid infarction after UAE is strongly associated with the risk of experiencing treatment failure. Patients with bleeding-related complaints only face the highest likelihood of treatment failure if UAE results in less than 90% fibroid devascularization.

Midterm results of uterine artery embolization using narrow-size calibrated embozene microspheres. Cardiovasc Intervent Radiol 2010; 34:295-305. [PMID: 20953610 DOI: 10.1007/s00270-010-9986-8] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2010] [Accepted: 08/26/2010] [Indexed: 12/20/2022]
Abstract
PURPOSE To evaluate safety and efficacy of uterine artery embolization using narrow-size-range polyphosphazene-coated hydrogel microspheres (Embozene, CeloNova Biosciences, Newnan, GA). METHODS Between May 2006 and September 2008, a total of 121 consecutive patients (mean ± SD age 42.1 ± 5.4 years, range 30.5-51.5 years) were enrolled onto this single-center study. The primary study endpoint was safety as assessed by the society of interventional radiology (SIR) classification. The secondary endpoint was efficacy, which was based on a 1-year magnetic resonance imaging study and relief of symptoms documented by the Medical Outcomes Study 36-Item Short-Form Health Survey questionnaire over a 2-year interval. RESULTS The mean ± SD diameter of the dominant fibroid was 6.4 ± 2.6 (range, 2.9-13.9) cm and the mean volume 137.2 ± 245.1 (range, 5.3-1184) ml. Most patients had multiple fibroids with 11% more than 10. A total of 240 of 242 interventions were completed as planned, a technical success rate of 99.2%. According to the SIR classification, one type A, eight type C, and one type D complication occurred. Total devascularization was noted in 96% (116 of 121) of dominant fibroids. Volume decrease was 4% at 2 weeks, 52% (P < 0.001) at 3 months, 78% (P < 0.001) at 6 months, and 91% at 12 months (P < 0.001). The latter difference was statistically significant (P = 0.007). A total of 92% had improved hypermenorrhea at 1 year and 94% at 2 years. Dysmenorrhea was improved in 96% at 1 year and in 95% at 2 years. The overall health status score was 60.4 ± 26.2 points at baseline and 96.9 ± 3.8 after 1 year (P = 0.0019). CONCLUSION Uterine artery embolization with Embozene microspheres is a safe procedure. Its efficacy is demonstrated by high fibroid devascularization and volume reduction rates and significant improvements of clinical symptoms and quality-of-life scores during follow-up.

Abstract
Follow-up controls in patients after uterine fibroid embolization (UFE) should monitor clinical improvement of symptoms, document shrinkage of the fibroids, exclude malignancies and detect and treat potential complications of the intervention.A close cooperation with the referring gynecologist, sufficiently and carefully informing the patient about the routine follow-up procedure, potential complications and their clinical signs are necessary to fulfill this goal.Imaging is usually based on ultrasound imaging but may be supplemented by MRI. There are different complications in the early phase after UFE and in the later postembolization phase.
