Abstract:Objectives To investigate the effect of cervical cancer surgery on postoperative pelvic floor functional including micturition function, defecation function and sexual dysfunction. Methods A total of 40 cases of cervical cancer patients (study group) and 40 cases of uterine benign patients (control group) who were admitted into the third affiliated hospital of Guangzhou medical university from January 2014 to June 2016 received hysteretomy and were collected into this study. Pelvic floor functions such as free urine flow rate, residual urine, pelvic floor electrical physiological function, nerve damage and quality of life were recorded for further analysis. Results The incidence of postoperative bladder dysfunction in study group increased dramatically when compared with control group (35.0% vs 5.0%, P < 0.05). The incidence of intestinal dysfunction in study and control group were not statistically different (16.3% vs 10%, P > 0.05). The incidence of sexual dysfunction in study enhanced significantly when compared with control group (56.7% vs 20%, P < 0.05). The postoperative PFDI-20 and PISQ-12 questionnaire analysis further confirmed the above findings (P < 0.05). Record of postoperative maximum urinary flow rate, average urine flow rate, residual urine volume, whether to use abdominal pressure mediated urination and nerve damage suggested that patients in study group experienced worse when compared with control group(P < 0.05). Type muscle fiber strength was significantly worse in study group when compared with control group(P < 0.05), while no difference in type muscle fiber strength was observed (P > 0.05). Conclusions Incidence of pelvic floor dysfunction, lower quality of life, abdominal pressure mediated urination, decrease of type muscle fiber strength and nerve damage caused by radical hysterectomy are higher compared with hysteretomy.
