Few studies have analyzed factors that influence longitudinal changes in patient-perceived satisfaction during the recovery period following robot-assisted radical prostatectomy (RARP) for prostate cancer. We investigated variables that were associated with patient-perceived satisfaction after RARP using the expanded prostate cancer index composite (EPIC) survey.


Of 175 men who underwent RARP between 2010 and 2011, 140 men completed the EPIC questionnaire preoperatively and 3, 6 and 12 months postoperatively. On the basis of the EPIC question no. 32 (item number 80), patients were divided into four groups according to the pattern of satisfaction change at postoperative 3 and 12 months: satisfied to satisfied (group 1); satisfied to dissatisfied (group 2); dissatisfied to satisfied (group 3); and dissatisfied to dissatisfied (group 4). Longitudinal changes in EPIC scores over time in each group and differences in EPIC scores of each domain subscale between groups at each follow-up were analyzed. A linear mixed model with generalized estimating equation approach was used to identify independent factors that influence overall satisfaction among repeated measures from same patients.


On the basis of the pattern of satisfaction change, groups 1, 2, 3 and 4 had 103 (74.3%), 21 (15.0%), 11 (7.9%) and 5 (2.9%) patients, respectively. The factor that was associated with overall satisfaction was urinary bother (UB) (β=0.283, 95% confidence interval (0.024, 0.543 ); P=0.033) adjusted for other factors under consideration.


UB was the independent factor influencing patient-perceived satisfaction after RARP. During post-RARP follow-up, physician should have the optimal management for the patient's UB.
