The Prevalence of Adenomyosis in Patients Who Underwent Hysterectomy for Benign Gynecological Diseases

Objective: Adenomyosis is a common benign gynecological condition, yet its exact prevalence and associated factors remain subjects of investigation.This study aimed to determine the prevalence of adenomyosis in patients who underwent hysterectomy for benign indications at our clinic and to analyze the demographic and clinical characteristics associated with the condition.Method: This retrospective study was conducted at the University of Health Sciences Turkey, Prof. Dr. Cemil Tacolu City Hospital.The histopathology reports of 1734 patients who underwent hysterectomy for benign reasons between January 2016 and December 2020 were reviewed.Patients were divided into two groups based on the presence or absence of adenomyosis.Demographic data, clinical presentations, surgical indications, and co-existing pathologies were compared between the groups.Statistical analysis was performed using SPSS 27.0. Results:Adenomyosis was histopathologically confirmed in 526 of the 1734 patients, yielding a prevalence of 30.3%.Patients in the adenomyosis group had significantly higher mean age (51.4 vs. 50.2years, p<0.001), gravida (4.49 vs. 3.67, p<0.001), and parity (3.21 vs. 2.77, p<0.001).The most common presenting symptom in the adenomyosis group was abnormal uterine bleeding (59.2%).Leiomyoma was the most frequent co-existing pathology, found in 48.9% of adenomyosis cases.Notably, pure adenomyosis without any accompanying pathology was identified in 22.6% of the cases.
