Damage of genitourinary system is possible complication after hysterectomy. Hysterectomy might increase the risk of lower urinary tract symptoms such as urgency, urinary incontinence, and the feeling of incomplete voiding. In this study, we aimed to evaluate the frequency of lower urinary tract symptoms in patients who have undergone abdominal or vaginal hysterectomy for benign indications.

In this prospective cohort study, women who has had abdominal or vaginal hysterectomy for benign indications, including myoma, adenomyosis, and pelvic pain or pressure were evaluated regarding lower urinary system symptoms, including urgency, feeling of incomplete voiding, and stress or urgency urinary incontinence, six months after surgery, using the FLUTS (Female lower urinary tract symptoms) standard questionnaire.
Demographic information, including age, parity, body mass index (BMI), history of smoking, uterus size (recorded in the pre-operative ultrasound or post-operative pathology results), and the indication for hysterectomy were also collected. 
The data was analyzed using SPSS software version 26. The results of the FLUTS questionnaire in the two study groups were compared using the Man-Whitney U test.

Prevalence of the filling symptoms (including nocturia, urgency, dysuria, and frequency) and the impact of these symptoms on the patients' quality of life did not significantly differ between the two groups (p>0.05). Regarding the prevalence of the voiding symptoms (including hesitancy, straining, and Intermittency) and the impact of these symptoms on the patients' quality of life, there were no statistically significant differences between the two groups in these fields (p>0.05). The difference in the frequency of incontinence symptoms and the effect of these symptoms on the patients' quality of life was not statistically significant in the two groups (p>0.05).

The prevalence of lower urinary tract symptoms does not significantly differ after abdominal or vaginal hysterectomy. Designing and implementing larger studies and assessing symptoms for extended periods seem necessary to validate the current findings.

The results of this research indicated that some filling disorder symptoms like frequency, nacturia and voiding dysfunction were more frequent in vaginal hysterectomy group but urgency, urgency urinary incontinence and bladder pain symptoms were more frequent in the abdominal hysterectomy group, although these differences were not significant between 2 groups. Moreover the impact of these symptoms on the patients' quality of life had no significant relationship with the type of hysterectomy.
