Doppler Ultrasonography in the Diagnosis of Dogs With Benign Prostatic Hyperplasia and Investigation of the Efficacy of Finasteride in Treatment.
Article in Veterinary medicine and science, 2025. 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
backgroundBenign prostatic hyperplasia (BPH) is a prevalent condition affecting the prostate gland in adult male dogs, often resulting in significant clinical manifestations. Doppler ultrasonography offers a non-invasive method to assess prostatic haemodynamics and vascular properties, which are crucial for understanding the pathophysiology of BPH and treatment effects.
objectivesThis study aimed to evaluate the effects of finasteride treatment on the haemodynamic and vascular properties of the canine prostate using B-mode and Doppler ultrasonography.
methodsSixteen dogs of different breeds, body weights (20-43 kg) and ages (6-13 years) were used in the study and classified into a healthy control group (n = 8) and a BPH group (n = 8). BPH presumptive diagnosis was performed through reproductive history, clinical signs (tenesmus, haematuria or dysuria) and prostatic volume by B-mode ultrasonography. The BPH group received finasteride treatment for 2 months. Prostate volume (PV), peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) were measured before and after treatment using B-mode and Doppler ultrasonography.
resultsThe BPH group exhibited a significant reduction in PV from 25.10 ± 18.55 cm
conclusionsFinasteride treatment is effective in reducing PV and improving blood flow parameters in dogs with BPH. Doppler ultrasonography is a valuable tool for monitoring treatment response and assessing prostatic haemodynamics in canine BPH.
