ProACT — Adjustable Continence Therapy (Periurethral Balloons)
The ProACT (Adjustable Continence Therapy) system is a minimally invasive periurethral balloon device FDA-approved in 2015 for male SUI, primarily post-prostatectomy. First introduced in 2000.[1][2][3]
For positioning vs other minimally invasive male SUI options, see Male Urethral Slings — chooser.
ProACT is not a sling — it is a periurethral balloon system. The device works by focal compression at the bladder neck, not by repositioning or by suburethral compression along the bulbar urethra.
Device design and mechanism
Two silicone balloons placed bilaterally at the bladder neck augment urethral coaptation through titrated focal compression — not circumferential occlusion. Each balloon connects via a conduit to a titanium port placed in the scrotum, allowing percutaneous volume adjustment under local anesthesia in clinic.[1][2]
Surgical technique
- General or local anesthesia.
- Implantation guided by fluoroscopy, transrectal ultrasound (TRUS), or flexible cystoscopy. TRUS-guided placement has shown comparable success and complication rates to fluoroscopic technique.[2][4]
- Balloons begin at low fill volume and are progressively titrated in clinic over multiple sessions to achieve continence without retention.
- Intraoperative bladder perforation occurs in ~ 2.5% of cases; transient retention in ~ 1.2%.[2]
Efficacy
All evidence is observational — no randomized controlled trials exist.
| Study | Design / n | Follow-up | Key outcome |
|---|---|---|---|
| Larson 2019 meta[5] | SR/meta of 19 studies, n = 1,264 | Mean 3.6 yr | Pads/day 4.0 → 1.1; dry rate 60.2%; dry-or-improved 81.9%; I-QOL +30.8 |
| Tricard 2023 meta[6] | Updated SR/meta, 18 studies, n = 1,570 | Mean ~ 3 yr | Dry rate 53% by strict 0–1 PPD definition |
| Nash 2019 (FDA pivotal)[7] | Prospective, n = 68 | 4 yr | 24-h pad weight 293 → 73 g; 1 procedure-related serious AE |
| Finazzi Agrò 2019 multicenter[8] | National Italian, n = 240 | 24 mo (152 pts to 5 yr) | 29.6% dry / 37.5% improved (67.1% combined); maintained at 5 yr |
| Nestler 2019 long-term[9] | Single-center, n = 134 | Median 118 mo | 82.6% initial success; 77.8% success after repeat implantation |
Efficacy by severity
Outcomes are stratified — mild 85% dry / moderate 63.6% / severe 33.3% in the Gregori TRUS-guided series.[2] Severe SUI is consistently associated with lower dryness across studies.[2][4]
Complications and durability
Overall complication rate 22.5–31.2% across series.[6][8] A 2025 SR of 1,607 patients catalogued 752 adverse events — most common categories:[10]
- Mechanical / balloon failure — 30%
- Device migration / malposition — 21%
- Device erosion — 16%
| Metric | Value |
|---|---|
| Explantation rate | 24–26.5%[6][11] |
| Reoperation rate | 22.7–34%[4][6] |
| Working device at 1 / 2 / 3 yr | 76% / 61% / 58%[11] |
Device longevity is the principal long-term concern. Working-device rates compare unfavorably to ATOMS (92% / 85% / 81% at 1 / 2 / 3 yr in the same Angulo 2019 meta).[11]
Negative predictive factors
- Prior pelvic radiotherapy is the most consistent negative predictor — dryness ~ 35–46% irradiated vs ~ 66–68% non-irradiated, and significantly higher urethral-erosion rates (p = 0.005). Multiple reviews advise against use in irradiated patients.[2][3][6][12]
- Severe baseline incontinence consistently predicts lower dryness.[2][4]
Salvage role after failed sling
Munier 2020 — n = 26 with persistent SUI after a prior sling failure: 66.7% continence and 96.3% improvement with ProACT, supporting feasibility as a salvage option when AUS is undesired or contraindicated.[13]
Comparative evidence — ATOMS-vs-ProACT meta
The Angulo 2019 PLoS meta is the definitive head-to-head — ATOMS superior across every endpoint:[11]
| Endpoint | ATOMS | ProACT | p |
|---|---|---|---|
| Dryness | 68% | 55% | 0.01 |
| Improvement | 91% | 80% | 0.007 |
| Satisfaction | 87% | 56% | 0.002 |
| Explantation | 5% | 24% | < 0.001 |
| Working device 3 yr | 81% | 58% | — |
Current positioning
ProACT is best suited for non-irradiated men with mild-to-moderate post-prostatectomy SUI who are not ideal AUS candidates (limited manual dexterity, declined implant) or who prefer a minimally invasive, adjustable, and reversible option.[3][5] Notably, ~ 29% of ProACT patients in one series ultimately required AUS — counsel that it is a step on the ladder, not necessarily a definitive endpoint.[4]
