Hemostatic effect and psychological impact of an oxidized regenerated cellulose patch after transrectal ultrasound-guided prostate biopsy: A prospective and retrospective study

To investigate the usefulness of the oxidized regenerated cellulose patch (ORCP) for postbiopsy hemostasis, anxiety, and depression in patients undergoing transrectal ultrasound-guided prostate biopsy. This was a prospective-retrospective study of 300 patients who underwent systematic 12-core prostate biopsy from August 2016 through March 2018. The ORCP was inserted into the rectum immediately after prostate biopsy in the prospective group (n = 150), while the retrospective group (n = 150) underwent prostate biopsy alone. The frequency rate and duration of hematuria, rectal bleeding, and hematospermia were compared between the 2 groups. Anxiety and depression were assessed with the hospital anxiety and depression scale before and after prostate biopsy in the prospective group. The frequency rates of hematuria and hematospermia showed no significant differences between the prospective versus retrospective groups (64.7% vs 66.7%, P = .881; 18 vs 20%, P = .718; respectively). Frequency of rectal bleeding was significantly lower in the prospective group than in the retrospective group (26.7% vs 42.7%, P = .018). However, there were no significant differences in median duration of rectal bleeding, hematuria, or hematospermia between the 2 groups (2, 5, and 2 days vs 2, 7, and 1 day, P > .05, respectively, for the prospective vs retrospective group). Multivariate analysis found that ORCP insertion was a significant protective factor against postbiopsy rectal bleeding (P = .038, odds ratio 0.52). Only anxiety level in the prospective group before versus after prostate biopsy was significantly reduced (5 vs 4, P = .011). ORCP insertion after prostate biopsy is an effective and simple method for decreasing rectal bleeding. ORCP insertion may also alleviate anxiety in patients undergoing prostate biopsy.
