A Prospective Study of the “Role of Penile Doppler Ultrasound and Sonoelastography in Understanding Erectile Dysfunction” at KIMS Hospital, Bengaluru (Code-T0111)

Introduction: Erectile dysfunction (ED) is a prevalent condition affecting men worldwide, with multifactorial etiologies including vascular, neurogenic, and psychogenic causes. Penile Doppler ultrasound (PDU) and sonoelastography have emerged as valuable tools for understanding the vascular and structural changes contributing to ED. This study explores the role of these imaging modalities in the comprehensive evaluation of ED.

Aim and Objective

Aim:

To study the treatment outcomes of patients with liver abscess in a tertiary care hospital.

Objectives:

1. To analyze the clinical characteristics (demographics, abscess characteristics, and extent) of patients with liver abscess.
2. To identify complications and clinical presentations along with hematological and biochemical parameters.
3. To evaluate the treatment modalities used.
4. To compare the outcomes of different treatment approaches.

Methods: This prospective study was conducted on 50 male patients with clinically diagnosed ED at KIMS Hospital, Bengaluru. All participants underwent clinical assessment, detailed history-taking, and standardized questionnaires. Penile Doppler ultrasound was performed to evaluate vascular parameters, including peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI). Sonoelastography assessed the tissue stiffness and structural integrity of penile tissues. Data were analyzed to identify correlations between imaging findings and clinical severity of ED.

Results: Penile Doppler revealed vascular abnormalities in 70% of cases, with arterial insufficiency being the most common finding (60%). Sonoelastography identified significant differences in tissue stiffness between patients with vascular and non-vascular ED (p < 0.05). Combined use of PDU and sonoelastography improved diagnostic accuracy to 90%, aiding in differentiation of underlying causes.

Conclusion: Penile Doppler ultrasound and sonoelastography are effective, non-invasive tools for diagnosing and understanding ED. Their combined use enhances diagnostic precision, enabling tailored therapeutic interventions.
