Experience of 5 years adjustable continence therapy (ProACT): the surgical learning curve and patient outcomes.
Article in World journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePost-prostatectomy urinary incontinence (PPI) significantly impacts quality of life. While an artificial urinary sphincter is the standard surgical treatment for PPI, adjustable continence therapy balloons (ProACT) have emerged as a less invasive alternative over the past two decades. ProACT implantation is considered technically challenging and limited to three high-volume Dutch medical centers, yet little is known about the surgical learning curve. This study aims to assess the learning curve to inform training requirements for ProACT implantation.
methodsThis retrospective single-center study included all ProACT implantations performed by one urologist at Erasmus University medical Center, Rotterdam. Surgery success was defined as postoperative use of a maximum of one 'safety pad', less than 10 mL urine loss or ≥ 95% subjective improvement of continence. Multivariable logistic regression assessed the learning curve.
resultsA total of 108 surgeries between 2019 and 2024 were included, of which 15 were supervised by an experienced surgeon. No statistical relation was found between the progressive surgeon's experience and surgical success (per 10 surgeries, OR 0.89, 95%CI: 0.75-1.07, p = 0.2). Preoperative incontinence (pads/day) was statistically significantly associated with surgical success (OR 0.65, 95%CI: 0.47-0.89, p = 0.009). The overall surgical success rate was 61%, with an additional 20% achieving > 50% continence improvement. Complication rate within six months was 21% of which six (5.6%) included explantations of the ProACT device.
conclusionProACT implantation achieves consistent outcomes after brief supervised training, with no statistically significant learning curve. This supports a broader adoption of this technique by urologists treating PPI.
