Uterine myomas and lower urinary tract dysfunctions: A literature review

Different types of urinary symptoms associated with myomas are reported, including urinary incontinence or dysuria. They are rarely investigated in patients and their prevalence is not well known. While myomas are the first reason to perform hysterectomy in France, few studies have evaluated the impact of surgical treatment in women with urinary symptoms. Our objective was to conduct a review of the literature regarding urinary symptoms associated with myomas and the impact of their treatment on these symptoms. We reviewed articles indexed in MEDLINE dealing with urinary symptoms and myomas, and published until September 2018. The prevalence of urinary symptoms in women with uterine myomas is highly variable depending on whether the authors are interested in symptoms or urodynamic results. The most frequently reported urinary symptoms are urgency (31-59%), dysuria (4-36%) and stress urinary incontinence (SUI, 20 80%). While some studies have found the anterior location of myomas and the size superior to 5 cm as a risk factor for UI, other studies have not found a correlation between myomas topography and symptom scores. The treatments of uterine myomas seem to have an impact on women's urinary symptoms. Although hysterectomy is considered as a risk factor for pelvic floor disorders, the removal of the uterus may sometimes improve or cure urinary symptoms. Most authors also found a significant improvement in urinary symptom scores after myomectomy and myomas embolization. More studies are needed to clarify the impact of myomas treatment on urinary symptoms.
