Abstract:
Objective:To investigate the influence of the degrees of intravesical prostatic protrusion (IPP) on the recovery of urinary continence after radical prostatectomy.
METHODS:We retrospectively analyzed the clinical data on 212 patients diagnosed with prostate cancer by biopsy and treated by laparoscopic radical prostatectomy by the same surgeon. Based on the degrees of IPP measured by MRI, we divided the patients into an IPP ≤ 10 mm group (n = 146) and an IPP > 10 mm group (n = 66) and determined the factors influencing the recovery of urinary continence by univariate and multivariate logistic regression analyses.
RESULTS:At 1, 3, 6 and 12 months after surgery, the urinary continence rates of the patients were 32.5%, 50.5%, 82.1% and 91%, respectively. Univariate analysis indicated that the factors influencing the recovery of urinary continence included IPP, body mass index (BMI), bladder neck preservation (BNP), neurovascular bundle preservation (NVBP) and clinical tumor (T) stage at 3 months (P < 0.05 or P < 0.01), age, IPP, BMI, BNP and clinical T stage at 6 months (P < 0.05 or P < 0.01), and age, IPP, BMI, BNP, NVBP and clinical T stage at 12 months (P < 0.05), while multivariate logistic regression analysis showed the independent influencing factors to be IPP > 10 mm (P < 0.001), BMI ≥ 25 kg/m2 (P = 0.004) and BNP (P = 0.032) at 3 months, and IPP and BMI at 6 months (both P < 0.01) and 12 months (P < 0.01 and P = 0.033).
CONCLUSIONS:IPP > 10 mm and BMI ≥ 25 kg/m2 are independent factors influencing the long-term recovery of urinary continence after radical prostatectomy.
