    Abstract:
    OBJECTIVES: To test the effectiveness of weekly postoperative pelvic floor muscle training (PFMT) versus supportive telephone contact by a urology nurse for men at 4 weeks after radical prostatectomy. METHODS: This was a randomized controlled trial in three Canadian centers. At 4 weeks after surgery, standardized verbal and written instruction about PFMT was provided to all subjects. Randomization occurred after initial instruction. Continence was defined as 8 g or less of urine loss on a 24-hour pad test. Primary outcome was grams of urine loss on pad test; secondary outcomes were International Prostate Symptom Score (IPSS), Incontinence Impact Questionnaire (IIQ-7) score, cost, and perception of urine loss as a problem. Data were obtained at baseline (preoperatively) and at weeks 4, 8, 12, 16, and 28 and 1 year after surgery. RESULTS: A total of 216 men were enrolled; 11 were dry or withdrew at 4 weeks. Ninety-nine were randomized to the control group and 106 to the treatment group. There were no group differences at baseline for prostate-specific antigen level (mean [standard deviation] 8.4 [10.4] ng/mL; 7.6 [4.6] ng/mL), Gleason score (6.3 [0.86]), IPSS, IIQ-7 score, pad test, or voiding diary. At 8 weeks 23% of the control group and 20% of the treatment group were continent; at 12 weeks, 28% and 32%; 16 weeks, 40% and 44%; 28 weeks, 50% and 47%; and at 52 weeks, 64% and 60%, respectively. There were no significant differences between groups at any time point for the outcome variables. CONCLUSIONS: Verbal instruction and written information with telephone support seemed to be as effective as intensive PFMT. Less-intense therapy may be more cost-effective.
