Abstract
BACKGROUND: Urinary incontinence symptoms severely affect older people with different body mass index (BMI).To compare the efficacy of the pelvic floor muscle training (PFMT) in patients with post-prostatectomy incontinence with different BMI. METHODS: Thirty-seven patients with post-prostatectomy incontinence were included. They were divided into group A (BMI ≤ 25,12), group B (26 ≤ BMI ≤ 30,14), and group C (BMI ≥ 31,11) based on difference BMI. Three groups of patients underwent the same Pilates combined with kegel training. Participants were assessed with 1-hour pad test, the number of incontinence episodes, International Consultation on Incontinence Questionnaire and Oxford Grading Scale. RESULTS: In the 1-hour pad test, the differences before and after training were statistically significant in all three groups of participants. Group A decreased from 81.83 ± 8.79 to 31.08 ± 5.64 g (P < 0.01). Group B decreased from 80.57 ± 8.87 to 35.85 ± 5.66 g (P < 0.01). Group C decreased from 83.55 ± 10.24 to 40.18 ± 7.01 g (P < 0.01). The number of incontinent episodes in group A decreased from 9.33 ± 1.07 to 3.25 ± 0.62 (P < 0.01). Group B decreased from 8.86 ± 1.09 to 3.79 ± 0.80 (P < 0.01). Group C decreased from 9.27 ± 1.10 to 4.09 ± 0.70 (P < 0.01). The correlation between the three groups of participants and the 1-hour pad test, with an R(2) of 0.51. The correlation between the three groups of participants and the number of urinary incontinence episodes with a R(2) of 0.43. CONCLUSIONS: Pelvic floor muscle training can affect the recovery of urinary continence in patients with different BMI. Maintaining a lower BMI can be beneficial for improving urinary control.
