Renal parenchymal volume analysis: Clinical and research applications

Area of Science:

• Urology
• Nephrology
• Medical Imaging

Background:

• Renal parenchymal volume directly correlates with kidney function, serving as a proxy for split renal function (SRF).
• Parenchymal volume analysis (PVA) utilizes semiautomated software to predict SRF and new-baseline glomerular filtration rate (NBGFR) post-nephrectomy.
• PVA has replaced nuclear renal scans (NRS) in renal transplantation and is explored for kidney cancer management.

Purpose of the Study:

• To present a comprehensive review of parenchymal volume analysis (PVA) applications in urology.
• To discuss the clinical and research implications of PVA in urologic patient care and surgical decision-making.
• To encourage wider adoption of PVA in urologic practices beyond renal transplantation.

Main Methods:

• Review of key articles on renal PVA applications in clinical care and urologic research.
• Emphasis on clinically relevant findings and contributions to the field's progress.
• Focus on studies demonstrating PVA's role in predicting functional outcomes.

Main Results:

• Renal PVA is an established reference standard for predicting functional outcomes after renal surgery, offering improved accuracy over NRS-based estimates.
• PVA can be rapidly performed using routine preoperative imaging, facilitating point-of-care application.
• PVA enables precise research into functional recovery determinants post-partial nephrectomy, influencing surgical strategies.

Conclusions:

• PVA offers superior accuracy in predicting SRF and NBGFR compared to traditional methods.
• Despite its advantages, PVA is underutilized in urology outside of renal transplantation.
• Increased PVA utilization in urology is advocated to enhance patient care and advance research.
