BackgroundTo determine whether transrectal ultrasound and urologist_dually guided pelvic floor muscle exercise is associated with immediate, early and long-term urinary continence after radical prostatectomy.Materials and methodsData from 114 patients with localized prostate cancer (PC) who underwent RP at Henan Cancer Hospital from November 2018 to April 2021 were included in the retrospective study. Of the 114 patients, 50 patients in the observation group underwent transrectal ultrasound and urologist_dually guided PFME, and 64 patients in the control group underwent verbally_guided PFME. Contractile function of the external urinary sphincter was in the observation group was evaluated. The immediate, early and long-term urinary continence rates were assessed in both groups, and the factors affecting urinary continence were analyzed.ResultsThe urinary continence rate at 2 weeks and 1, 3, 6 and 12 months in the observation group after RP was significantly higher than that in the control group (52.0% vs. 29.7%, 70.0% vs. 39.1%, 82% vs. 57.8, 88% vs. 70.3%, 98.0 vs. 84.4%,p< 0.05). The contractile function of the external urinary sphincter was obviously correlated with urinary continence at multiple visits after RP, except for the 12-month visit. Transrectal ultrasound and urologist-dually guided PFME was verified to be an independent positive factor for urinary continence at 2 weeks and 1, 3, 6 and 12 months using logistic regression analysis. However, TURP was a negative factor for postoperative urinary continence at different times.ConclusionsTransrectal ultrasound and urologist_dually guided PFME had a significant role in improving immediate, early and long-term urinary continence after RP and acted as an independent prognostic factor.
