OBJECTIVETo study the urodynamic changes in patients with recent non-infective voiding dysfunction following radical hysterectomy and assess its significance.

METHODSNinety-six patients with cervical cancer, who were not found any abnormal representation of urodynamics before the operation, were selected into this study group. Eighty-three patients in the study group without urinary infection were detected by urodynamic examination following radical hysterectomy, in order to analyze the urodynamic reasons for the non-infective voiding dysfunction following the surgery.

RESULTSForty-two patients were found with non-infective voiding dysfunction after the operation. Low compliance bladder, bladder destrusor dysfunction and destrusor overactivity were the three leading types of postoperative bladder dysfunction. Moreover, the incidences of low compliance bladder (50.0% vs. 17.1%), bladder destrusor dysfunction (58.4% vs. 14.6%) and destrusor overactivity (31.0% vs. 4.9%) in the group with voiding dysfunction were significantly higher than the corresponding values in the group without voiding dysfunction (P < 0.01). Secondarily, forty-two patients with recent non-infective voiding dysfunction were divided into simple irritation sign group, simple obstruction sign group and mixed sign group according to their main symptoms. The incidence of bladder destrusor dysfunction in the simple obstruction sign group was significant higher than that in the simple irritation sign group, and the incidence of detrusor overactivity in the simple irritation sign group was significant higher than that in the other two groups (P < 0.05).

CONCLUSIONSThere were many different types of urodynamic disorder in the patients with recent non-infective voiding dysfunction after radical hysterectomy. Low compliance bladder, bladder destrusor dysfunction and detrusor overactivity caused by the damage of the pelvic autonomic nerve during the operation may be the main reasons for the recent non-infective voiding dusfunction after radical hysterectomy. Moreover, bladder destrusor dysfunction and detrusor overactivity may be the key points for the symptoms of bladder irritation and bladder obstruction. Urodynamic study is important for the etiology analysis and clinical treatment of recent non-infective voiding dysfunction postoperation.
