The application of polypropylene mesh for testicular prosthesis in surgical castration for patients with prostate...

To explore whether a polypropylene mesh is suitable for application as a new material for testicular prostheses.

The data of 65 patients with advanced prostate cancer who underwent surgical castration in hospital were collected and analyzed. Patients who preferred to undergo traditional orchidectomy (n = 16) were assigned to the control group, and patients who underwent subcapsular orchiectomy plus implantation of a polypropylene mesh testicular prosthesis (n = 49) were assigned to the experimental group. The presence of hematoma, infection, and other complications in patients in these two groups were investigated at 3 and 12 months following the surgery. The patients were also followed up using a self-designed testicular castration satisfaction questionnaire.

A higher score indicated greater satisfaction. The mean score was 15.33 ± 2.85 in the experimental group and 4.63 ± 1.45 in the control group at 3 months after the surgery. The mean score was 14.92 ± 1.74 in the experimental group and 4.25 ± 1.61 in the control group at 12 months after the surgery. The difference between the two groups was statistically significant at the two time points (P < 0.01).

Compared with orchidectomy alone, patients were more satisfied with subcapsular orchiectomy plus the implantation of a polypropylene mesh testicular prosthesis for the treatment of advanced prostate cancer. Furthermore, the polypropylene mesh testicular prosthesis maintained its original character over the duration of the study, with a good long-term effect. Thus, implantation of a polypropylene mesh testicular prosthesis is indicated to be safe and effective, and polypropylene mesh is potentially useful as a new material for testicular prostheses.
