Hemodynamic effects of sildenafil citrate (Viagra) on segmental branches of bilateral renal arteries.

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
introductionErectile dysfunction (ED) is one of the most encountered male health problem and sildenafil citrate is used worldwide for treatment of ED. Aim of the present study was to determine and evaluate hemodynamic effects of sildenafil citrate on segmental branches of bilateral renal arteries of cases with ED. PATIENTS AND
methodsTotal of 35 male patients aging between 34 and 56 years were recruited into study. Patients were evaluated with renal color Doppler sonography (CDS) before and after (45-75 min) peroral sildenafil citrate (50 mg) administration. Peak systolic flow rate (V(max)), end diastolic flow rate (V(min)), resistive index (RI) and pulsatility index (PI) of renal artery segmental branches were determined before and after sildenafil citrate administration.
resultsV(min) measured at right lower segment was significantly reduced after sildenafil administration (p = 0.030). Accordingly mean RI and PI of right lower segment of renal artery slightly increased after drug administration (p = 0.007 and p = 0.012, respectively). The measurements on other segments had no significant change after sildenafil treatment when compared to baseline values. On this single dose administration no side effect was recorded.
conclusionFindings of the present study demonstrated that peroral sildenafil citrate usage had slight effects on hemodynamic parameters of lower segmental branch of right renal artery. This result could not be interpreted as robust evidence for hemodynamic changes of renal arteries associated with sildenafil usage nevertheless warrants more comprehensive research with larger number of patients.
