Characterization of the histological response to the Butterfly Prostatic Retraction Device in patients with benign prostatic hyperplasia.

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
purposeThe Butterfly Prostatic Retraction Device ("Butterfly") is a permanent nitinol implant for benign prostatic hyperplasia. This study examines the chronic response of prostate tissue to the Butterfly in histological specimens from patients in the Butterfly pilot clinical study.
methodsRetrospective qualitative and semi-quantitative review of histological specimens of seven (7) patients who participated in the Butterfly pilot clinical study. Patients had at least 1-month implantation with the Butterfly prior to implant removal and TURP. Tissue samples were graded by two pathologists.
resultsFour out of six patients had IPSS decreased from baseline. All seven patients' samples had signs of chronic inflammation; one demonstrated acute inflammation and one demonstrated fibrosis. In three cases, intraglandular calcification was identified. There was no ischemic necrosis induced by the implant, and no encrustation, urethral edema, or cellular atypia was noted.
conclusionThe Butterfly demonstrated an overall favorable safety profile in terms of tissue response. This study demonstrates that there is no significant tissue reaction in the prostatic urethra due to presence of Butterfly device.
