Summary
Unilateral pelvic kidney is a rare condition where one kidney is located in the pelvis. Computed tomography (CT) effectively visualizes its key features, aiding diagnosis.
Area of Science:
- Radiology
- Urology
- Medical Imaging
Background:
- Congenital anomalies of the kidney and urinary tract (CAKUT) can lead to ectopic kidneys.
- Pelvic kidney, a form of renal ectopia, presents diagnostic challenges.
Purpose of the Study:
- To describe the computed tomography (CT) findings in unilateral pelvic kidney.
- To evaluate the utility of CT in diagnosing pelvic kidney.
Main Methods:
- Retrospective analysis of six unilateral pelvic kidney cases.
- Review of computed tomography (CT) scans, focusing on anatomical location, hilar orientation, and contrast enhancement patterns.
Main Results:
- Absence of kidney in the renal fossa with a normal contralateral kidney.
- Pelvic kidney with variable hilar orientation.
- Homogeneous parenchymal enhancement and clear visualization of the pyelocalyceal system on post-contrast CT.
Conclusions:
- Computed tomography (CT) is a valuable tool for diagnosing pelvic kidney.
- CT features, including renal fossa absence and specific enhancement patterns, aid in identification.
