Abstract

PURPOSE
Lower urinary tract dysfunction is the most common complication after radical pelvic surgery. The aims of this study were to assess the effect of radical hysterectomy (RH) on the storage function of the lower urinary tract and to evaluate the impact of radiation therapy (RT) on postoperative urodynamic parameters.
METHODS
This was a retrospective review of preoperative and postoperative urodynamic variables, which were prospectively collected. All women from 2006 to 2008, who underwent RH for uterine cervical cancer with a stage of 1A to 2B with or without adjuvant RT were enrolled. All patients were divided into two groups: group 1, without RT, and group 2, with adjuvant RT. Urodynamic studies were performed before, 10 days after, and 6 months after RH.
RESULTS
A total of 42 patients with a mean (+/-standard error) age of 51.9 (+/-12.3) years were analyzed. There were no significant differences in age, body mass index or clinical stage between the two groups. On the 10th postoperative day, all parameters were decreased except postvoid residual volume. In comparison with group 2 (n=14), group 1 (n=28) showed a significant increase in bladder compliance. At 6 months postoperatively, bladder compliance in group 1 had increased four times or more compared with that on postoperative 10 days. However, it had increased only 2.5 times in group 2 at the same time point (P<0.001).
CONCLUSIONS
The results of our study suggest that adjuvant RT after RH might result in a deterioration of bladder compliance. It is highly suggested that practitioners pay attention to low bladder compliance, especially in patients who have adjuvant RT after RH.
