What was done
This narrative review synthesized literature on the proposed mechanisms, clinical efficacy, and practical applications of vacuum erection devices (VED) and penile traction therapy (PTT) for treating post-radical prostatectomy sexual dysfunction, including erectile dysfunction, penile shortening, and structural tissue fibrosis.
What was found
The abstract reports no quantitative values or effect estimates. Qualitatively, VED enhances penile blood flow, preserves tissue integrity, and aids in maintaining penile length, though its capacity to accelerate the recovery of unassisted spontaneous erectile function remains uncertain. Preliminary evidence suggests PTT helps reduce penile shortening and support functional recovery, but long-term efficacy data are limited. Both modalities are hindered by poor adherence, a lack of standardized treatment regimens, and sparse data regarding combination with pharmacotherapy.
Why it matters
Penile atrophy and erectile dysfunction are frequent, distressing sequelae of prostate cancer surgery; mechanical interventions offer non-pharmacological options, but clinical practice lacks consensus on optimal usage.
Limits
As a narrative review, it lacks systematic search criteria, meta-analytic pooling, and risk-of-bias grading. The underlying literature is constrained by small study sizes, variable protocols, poor patient compliance, and a lack of rigorous, large-scale clinical trials assessing long-term functional outcomes.
