Can vacuum erection devices be used with penile implants or after prostate surgery?
Executive summary
Vacuum erection devices (VEDs) are an established, non‑invasive option both as a treatment for erectile dysfunction and as part of “penile rehabilitation” after radical prostatectomy; multiple reviews and clinical articles say VEDs increase penile blood flow, may help preserve length, and are routinely recommended after prostate surgery [1] [2] [3]. Use of an external vacuum device to augment an existing penile prosthesis has been reported in small series and surveys with most patients reporting increased rigidity, length or satisfaction, but the evidence is limited and mostly anecdotal or small‑sample [4] [5].
1. VEDs after prostate surgery: mainstream use and the rationale
Urology centers and review articles describe VEDs as a cornerstone of penile rehabilitation after radical prostatectomy because negative pressure distends the corporal sinusoids and increases oxygenated blood flow to erectile tissue; that physiologic effect is the stated mechanism for reducing fibrosis and preventing penile shortening after surgery [2] [1]. Systematic and narrative reviews conclude VEDs are “well‑known” and commonly used to improve recovery of erectile function and to preserve penile length; some guidelines and specialty centers recommend regular VED use early after surgery as part of a rehab program [3] [6] [7].
2. What outcomes the literature claims VEDs can deliver
Clinical reviews and institutional guidance list three commonly cited benefits after prostatectomy: increased local blood flow and oxygenation, reduced penile fibrosis/atrophy, and preservation of penile length; several papers report improved sexual satisfaction when VEDs are combined with other therapies such as PDE5 inhibitors [1] [8] [9]. A 2023 scoping review and other narrative reviews analyze different VED schedules and generally support VEDs’ role in rehabilitation though optimal timing/frequency remains debated [3] [6].
3. Practical protocols and patient guidance reported by clinics
Patient‑facing resources and centers advise early, regular use — some recommending multiple sessions per week or even daily/near‑daily initiation soon after catheter removal — and stress device features (vacuum limiter/pop‑off valve, quick release) and safe time limits for constriction rings (commonly cited: ≤30 minutes) [9] [10] [11]. Universities and cancer centers explicitly recommend talking to your urologist for a tailored schedule and emphasize that VED erections are mechanically induced and may take months to affect spontaneous erections [9] [7].
4. Using a VED with an implanted penile prosthesis: what the reports show
Evidence is sparse but existent: a small case series/survey found that external vacuum devices used to augment semirigid or inflatable prostheses led to reported increases in rigidity, length or girth and improved patient/partner satisfaction in 11 of 12 patients in that group [4]. A broader review notes research into VED use “before and after penile prosthesis insertion” is very limited, signaling clinicians have explored combined use but without large controlled trials [5].
5. Safety, limits and areas of uncertainty
Authors and major clinics caution about contraindications (patients at risk for priapism or bleeding disorders) and emphasize device safety features because poorly designed pumps have caused injury; long‑term randomized data comparing VEDs to other strategies or defining optimal rehab schedules are limited, and cost/coverage issues have driven some clinicians away from routine use despite supportive physiologic rationale [9] [1] [11]. Research into VED use specifically with penile implants or as routine adjunct pre/post‑op remains sparse and largely low‑level evidence (case series, expert opinion) rather than large randomized trials [5] [4].
6. Competing perspectives and clinical takeaways
Many urology reviews and centers present VEDs as a practical, first‑line rehabilitative tool after prostate surgery and a reasonable adjunct to other ED therapies [12] [1] [7]. Counterpoints are implicit: some practitioners question routine use because of cost, patient adherence, and incomplete high‑quality trial evidence for long‑term erectile function recovery [1] [3]. For penile implants, small reports suggest VEDs can augment prosthetic function for selected patients, but available literature does not give broad, high‑quality guidance — consult your implant surgeon before attempting combined use [4] [5].
