Abstract
A study to identify objective risk factors for development of urinary incontinence in patients with prostate cancer who underwent radical retropubic prostatectomy was conducted. Before surgery, magnetic resonance imaging to assess the length of the membranous segment of urethra and shape of the apex of the prostate was performed in 180 patients with prostate cancer. In addition, for the purpose to determine the effect on the risk of development of stress urinary incontinence after surgery, the authors evaluated such factors as age, body mass index, serum prostate specific antigen, prostate volume, postoperative stage prostate cancer, Gleason score, nerve-sparing surgical technique, surgical margin status. At a median postoperative follow-up of 9 months, the frequency of incontinence was 7.8%. Length of membranous segment of urethra, the shape of the apex of the prostate gland, and the patient’s age had a statistically significant effect on the risk of urinary incontinence after the intervention.
