Abstract:
OBJECTIVE: To study the effect of urodynamic factors on the urinary retention of the patients with cervical cancer received radical hysterectomy. METHODS: Seventy-two patients with cervical cancer International Federation of Gynecology and Obstetrics (FIGO) stage Ib1 to IIa hospitalized in Fujian Provincial Maternity and Child Health Hospital between June 2006 and August 2009, who were not found any abnormal representation of urodynamics before the operation, were divided into the group with urinary retention and the group without urinary retention based on whether urinary retention after the operation. All patients were detected by urodynamic examination following radical hysterectomy. Data obtained from urodynamic examination were analysed by logistic regression to evaluate the influence of urodynamic factors on the urinary retention postoperation. RESULTS: Twenty-one patients out of all were found with urinary retention after the operation, the incidence rate of urinary retention was 29%. The first sensation after operation in both groups were increased significantly than those before operation [(171 ± 61) ml vs. (126 ± 28) ml, (134 ± 39) ml vs. (119 ± 17) ml, all P < 0.05], while the maximum volume [(337 ± 66) and (300 ± 66) ml, respectively], the compliance [(31 ± 25) and (29 ± 18) ml/cm H2O (1 cm H2O = 0.098 kPa), respectively], the maximum flow rate [(10 ± 4) and (12 ± 5) ml/s, respectively] and the pressure at the maximum flow rate [(27 ± 9) and (32 ± 8) cm H2O, respectively] were decreased obviously after radical hysterectomy in both the group with urinary retention and the group without urinary retention (all P < 0.05), compared with the corresponding value before the operation. The urodynamic changes in urinary retention group was much more severe than those in group without urinary retention (P < 0.05). The single factor analysis results showed that bladder destusor dysfunction (OR = 8.20, 95%CI: 2.62-25.66, P < 0.01) and lack of sensation (OR = 6.90, 95%CI: 1.95-24.43, P < 0.01) were relevant to the urinary retention post-operation. While there were not relationship was found between low compliance bladder (OR = 1.99, 95%CI: 0.70-5.63, P = 0.195), detrusor overactivity (OR = 2.51, 95%CI: 0.73-8.67, P = 0.144), bladder outlet obstruction (OR = 3.77, 95%CI: 0.76-18.57, P = 0.104) or dyssynergia of urethral external sphincter (OR = 2.67, 95%CI: 0.49-14.45, P = 0.255) and urinary retention following the operation. There were an antagonistic effects (OR = 7.60, 95%CI: 1.43-40.39, P = 0.017) of detrusor overactivity and bladder destrusor dysfunction on urinary retention. The multiple factors analysis results revealed that bladder destusor dysfunction (OR = 7.01, P < 0.01) and lack of sensation (OR = 5.45, P = 0.018)were the independent risk factors influencing on the urinary retention post-operation. CONCLUSIONS: There are obvious urodynamic change in cervical cancer patients following radical hysterectomy. Bladder destrusor dysfunction and lack of sensation are the independent urodynamic risk factors influencing on urinary retention following radical hysterectomy, while detrusor over activity may be a protective effect on bladder destrusor dysfunction post-operation in some degree. Urodynamic test is important for analysis and treatment of urinary retention following radical hysterectomy.
