Silicone penile prosthesis without suprapubic lipectomy for buried penis: a pilot study on the efficacy of HimplantTM.

Adult acquired buried penis (AABP) is a condition where the penile shaft becomes concealed by surrounding tissues, often due to obesity, leading to significant physical and psychological distress. This pilot study evaluates the efficacy of Himplant^TM (International Medical Devices Inc., Beverly Hills, CA, USA), a subcutaneous silicone penile prosthesis, for correcting AABP without concurrent manipulation of suprapubic fat. Twelve adult patients (mean age 39.1 ± 10.8 years) underwent Himplant^TM insertion between January 2023 and May 2024. Standardized pre- and postoperative measurements showed a mean increase of 3.52 ± 0.41 cm in flaccid dorsal length and 2.78 ± 0.54 cm in midshaft girth (p < 0.0001). A non-validated follow-up questionnaire revealed that 85.7% of respondents (6/7) reported improved self-confidence in both daily life and sexual activity. The overall complication rate was low and limited to minor, conservatively managed issues; there were no penile infections, penile skin erosions, or other cases requiring implant removal. Notably, no recurrences of AABP were observed during a median follow-up period of 16.5 months. These findings suggest that Himplant^TM may offer a safe, effective, and minimally invasive surgical solution for AABP, improving both functional outcomes and psychosocial well-being.
