Impact of uterine fibroid surgery on lower urinary tract symptoms

Prevalence of Lower Urinary Tract Symptoms in Women Planning to Undergo Hysterectomy for Uterine Leiomyoma and Abnormal Uterine Bleeding

Introduction: Leiomyomas are associated with lower urinary tract symptoms (LUTS), but more specific characterization of their impact on LUTS is needed. Methods: This is a retrospective cohort study of 202 participants (101 per group) who underwent hysterectomy for leiomyomas versus abnormal uterine bleeding nonclassified (AUB-N) from July 2015 to May 2019. Baseline demographics, leiomyoma characteristics, and presence of baseline LUTS were collected. The main objective was to compare the prevalence of LUTS between these two groups. Secondary objectives were to analyze the association between leiomyoma characteristics and the prevalence of LUTS. Results: There was no difference in baseline prevalence of LUTS between the hysterectomy for leiomyoma versus AUB-N groups (42.6% vs. 45.5%, p = 0.67). When examining the entire study cohort of participants, irrespective of hysterectomy indication, leiomyoma size >6 cm was associated with an increased prevalence of LUTS when compared with leiomyoma <6 cm (64.9% vs. 40.4%, p = 0.02), and specifically difficulty passing urine (p = 0.02), nocturia (p = 0.04), and urinary frequency (p = 0.04). When controlling for age, body mass index, parity, chronic pelvic pain, and diabetes, leiomyomas >6 cm remained significantly associated with the presence of LUTS (odds ratio 3.1, 95% confidence interval = 1.2-8.3) when compared with leiomyoma <6 cm. Presence of >1 leiomyoma was associated with urinary frequency (67.9% vs. 32.1%, p = 0.02) when compared with ≤1 leiomyoma. Anterior location and uterine volume were not associated with a difference in LUTS. Conclusion: LUTS are prevalent in those planning hysterectomy for leiomyoma and AUB-N. Leiomyomas >6 cm are associated with the presence of LUTS. Future studies should evaluate change in LUTS following hysterectomy for leiomyomas.

Changes in Pelvic Floor Symptoms After Procedural Interventions for Uterine Leiomyomas: A Systematic Review

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.

Risk of overactive bladder after hysterectomy for uterine fibroids

INTRODUCTION AND HYPOTHESIS

We evaluated the association between previous hysterectomy for uterine fibroids and the risk of developing overactive bladder (OAB).

METHODS

We used national health insurance data. The hysterectomy group (aged 40 to 59) comprised patients who underwent hysterectomy for uterine leiomyoma or adenomyosis between 1 January 2011 and 31 December 2014, and the control group (aged 40 to 59) comprised patients who visited a medical facility for a checkup during the same time period. Propensity score matching (PSM, 1:1) was performed to balance confounders. OAB events were defined by drug prescriptions (beta 3 agonist or anticholinergics) for more than 1 month based on previous studies.

RESULTS

After matching, 58,195 cases (hysterectomy group) and 58,195 controls (nonhysterectomy group) were enrolled. The mean follow-up period was 7.9 years in the nonhysterectomy group and 8.0 years in the hysterectomy group. There was no significant difference in the rate of OAB development between the groups (0.3% vs 0.3%; p=0.061). Additionally, compared with the nonhysterectomy group (hazard ratio: 1 (reference)), hysterectomy without adnexal surgery (hazard ratio: 1.169 [0.915-1.493]) and hysterectomy with adnexal surgery (hazard ratio: 1.342 [0.83-2.171]) did not significantly increase the risk of OAB after adjusting for confounders; this relationship remained nonsignificant after stratifying patients according to age group.

CONCLUSIONS

Previous hysterectomy with or without adnexal surgery for the treatment of uterine fibroids did not increase the risk of developing OAB, defined as drug therapy lasting more than 1 month.
