Urographic visualization of multicystic kidneys

Area of Science:

• Nephrology
• Radiology
• Medical Imaging

Background:

• Multicystic dysplastic kidney (MCDK) is a congenital anomaly.
• Traditionally, MCDK is characterized by non-functioning renal parenchyma.
• Radiographic visualization of renal parenchyma in MCDK is considered absent.

Purpose of the Study:

• To report on the radiographic visualization of renal parenchyma in pathologically confirmed cases of multicystic kidneys.
• To challenge the classical understanding of MCDK on excretory urography.

Main Methods:

• Retrospective review of 4 cases with pathologically confirmed multicystic kidneys.
• Analysis of excretory urograms to assess contrast medium concentration and visualization of renal tissue.

Main Results:

• Radiographic visualization of renal parenchyma was achieved in 4 cases of typical multicystic kidneys.
• Sufficient concentration of contrast medium allowed for visualization of renal tissue.

Conclusions:

• The findings suggest that functioning renal parenchyma can be visualized in some cases of multicystic kidneys.
• Excretory urography may reveal renal tissue in MCDK under specific conditions of contrast enhancement.
