Bilateral supernumerary kidneys in conjunction with horseshoe anomaly

Area of Science:

• Urology
• Radiology
• Medical Imaging

Background:

• Bilateral supernumerary kidney is an extremely rare congenital urogenital anomaly.
• Few cases of supernumerary kidneys have been documented in medical literature.
• The co-occurrence of supernumerary kidneys with fusion anomalies like horseshoe kidney is exceptionally rare.

Observation:

• A 63-year-old male presented with persistent lower abdominal pain.
• Diagnostic workup involved ultrasound, computed tomography (CT) scan, excretory urography, and retrograde pyelography.
• Radiological findings confirmed the presence of bilateral supernumerary kidneys and a horseshoe fusion anomaly.

Findings:

• This case represents the first reported instance of bilateral supernumerary kidneys coexisting with a horseshoe fusion anomaly.
• The complex urogenital anomaly presented diagnostic challenges.
• The patient's symptoms were attributed to this rare combination of congenital abnormalities.

Implications:

• Highlights the importance of thorough radiological evaluation in diagnosing rare urogenital anomalies.
• Contributes to the limited understanding of supernumerary kidney and fusion anomaly co-occurrences.
• Informs clinical decision-making and management strategies for patients with complex congenital kidney abnormalities.
