Color Doppler flow imaging diagnosis and treatment selection for erectile dysfunction

Area of Science:

• Urology
• Andrology
• Medical Imaging

Background:

• Erectile dysfunction (ED) diagnosis and treatment can be improved with targeted therapy.
• A standardized approach for targeted ED therapy is needed.
• This study investigated a targeted diagnosis and therapy model for ED.

Purpose of the Study:

• To establish a rational mode for targeted erectile dysfunction (ED) therapy.
• To investigate the efficacy of targeted diagnosis and treatment for ED.

Main Methods:

• 198 patients with ED underwent intracavernosal vasoactive agent injection followed by color Doppler flow imaging.
• Penile rigidity was assessed using the Schramek scale, categorizing patients into four groups (V, IV, III, II).
• Treatment recommendations were tailored to each patient's erection grade and Doppler findings.

Main Results:

• Significant differences in cavernosal artery blood flow indexes (peak systolic velocity, end diastolic velocity, resistance index) were observed among the four groups post-injection (P < 0.05).
• The resistance index showed significant differences between all group pairs (P < 0.05).
• Targeted therapy based on erection grade and Doppler imaging achieved a 91.91% clinical satisfaction rate.

Conclusions:

• Color Doppler flow imaging after intercavernosal injection, combined with Schramek erection grading, provides objective blood flow data.
• This targeted approach allows for personalized treatment recommendations for ED.
• The model significantly enhances clinical satisfaction for erectile dysfunction treatment.
