Assessing the Safety and Efficacy of the ClearRing™ Implant for the Treatment of Benign Prostatic Hyperplasia in a Canine Model.
Article in Current urology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundTransurethral resection of the prostate is the most common procedure for the treatment of benign prostatic hyperplasia (BPH). Although effective, transurethral resection of the prostate can be associated with side effects including prolonged recovery, storage and voiding symptoms, risk of acute urinary retention.
objectivesIn this study, we describe a new minimally invasive device for the treatment of lower urinary track symptoms due to BPH, implanting a nitinol C shape ring in a circular incision in the prostatic tissue, surrounding the urethra, done by electrocuting blade over a dilatation balloon.
methodsTwo groups of dogs (4/ group) were implanted with the device under anesthesia. Clinical observation, body weight and weekly blood and urinary tests were performed throughout the study period to evaluate safety. Fluoroscopy and cystoscopy were used throughout the study period to evaluate implant condition and urethral dilatation. At the end of 3 weeks (Group I) or 3 months (Group II), the animals were sacrificed. The implantation site was examined macroscopically and histologically to evaluate urethral dilatation and tissue response.
resultsThe presence of the ClearRing™ implant in an animal's prostate was associated with significant dilatation of the prostatic urethra. Fever, pain, behavior disturbances or gross hematuria, when occurred, resolved within 72 hours post procedure and no severe adverse events were observed. There was no evidence of prostatic hyperplasia associated to ring implantation. Partial epithelial coverage of the implant surface was observed without evidence of encrustation.
conclusionThe ClearRing™ implant seems a feasible minimally invasive procedure for relieving lower urinary track symptoms due to BPH.
