Diagnostic categorization of erectile dysfunction using duplex color doppler ultrasonography and significance of phentolamine redosing in abolishing false diagnosis of venous leak impotence: A single center experience.

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
BACKGROUND AND
aimsErectile dysfunction (ED) is an inability to achieve and maintain erectile rigidity sufficient for satisfactory sexual performance. It is either organic or psychogenic in origin. This study was aimed at establishing vasculogenic causes among patients being evaluated for ED using Penile Doppler Ultrasound.
methodsFifty-two consecutive patients with the clinical diagnosis of ED were evaluated with color Doppler ultrasound scan using a 7.5 MHz high-frequency linear transducer between July 2016 and June 2019. The examination was commenced 3 min after an intracavernosal injection with 10-20 μg of PGE
resultsPSV of cavernosal arteries (CA) varied between 19.2 and 106.2 cm/s (mean: 43.8 ± 18.2) among the entire patients and between 19.7 and 80.2 cm/s (mean: 42.6 ± 11.3) among patients with arteriogenic ED. Arteriogenic ED was found in 8 patients (15.3%), while venogenic ED was observed in 12 patients, which constituted 23% of the entire study population and mixed arteriogenic-venogenic ED was found in 6 patients (11.5%) of the study population. DICC performed on patients diagnosed with venogenic ED on color Doppler ultrasonography revealed venous leakage and no statistically significant differences between results of DICC and color Doppler ultrasonography were found in EDV, RI, and PI measurements (P< 0.005). Among patients with venogenic ED and mixed arteriogenic-venogenic ED,2 patients had a normal erectile response and the remaining 16 received 2 mg phentolamine. A significant increase in PSV between baseline and 20 mg PGE1 (
conclusionIn the current study, 50% of patients had vasculogenic ED and "false-positive'' diagnosis of venous leakage was unmasked by phentolamine re-dosing. It is therefore imperative that patients with ED benefit from duplex color Doppler ultrasonography which is safe, cheap and non-ionizing diagnostic modality before initiating therapy as ED treatment is cause specific.
