Summary
Color Doppler ultrasonography (DUSG) and indocyanine green (ICG) fluorescence imaging are safe for intraoperative renal perfusion assessment. DUSG is a cost-effective alternative for broader clinical use.
Area of Science:
- Urology
- Surgical Oncology
- Medical Imaging
Background:
- Intraoperative Color Doppler ultrasonography (DUSG) assesses renal parenchymal perfusion post-artery clamping.
- Comparison of DUSG with indocyanine green (ICG) fluorescence imaging and a control group is evaluated.
Purpose of the Study:
- To evaluate DUSG for intraoperative renal perfusion assessment.
- To compare DUSG outcomes with ICG fluorescence imaging and a control group.
Main Methods:
- Retrospective analysis of 426 patients (2018-2025).
- Ischemia verification using DUSG (n=174), ICG (n=29), or no imaging (control, n=223).
- Evaluation of demographic, oncological, and surgical parameters, including selective clamping, clamp adjustments, and positive resection margins (pR1).
Main Results:
- No significant differences in tumor size, BMI, blood loss, or warm ischemia time (WIT) across groups.
- Selective clamping was more frequent with DUSG and ICG versus controls (p < 0.001).
- Clamp adjustment rates: DUSG 24%, ICG 62%, control 3% (p < 0.001).
Conclusions:
- Intraoperative perfusion verification is beneficial for non-visible ischemia.
- Both DUSG and ICG are safe and reliable for assessing renal perfusion.
- DUSG is an effective, accessible, and economical alternative for widespread clinical adoption.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:19Assessing Blood pressure using a doppler ultrasound
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.
