Caudal regression with cake kidney and a single ureter: a case report

Area of Science:

• Urology
• Developmental Biology
• Medical Case Reports

Background:

• Congenital kidney anomalies present diverse challenges in diagnosis and management.
• Cake kidney, a rare fusion anomaly, and single ureter malformations require specific clinical consideration.
• Caudal regression syndrome encompasses a spectrum of developmental defects affecting the lower spine and limbs.

Observation:

• The study presents the second documented case of a cake kidney associated with a single ureter.
• This unique presentation is further complicated by the presence of caudal regression syndrome.
• The patient's clinical presentation highlights the intricate interplay of these congenital abnormalities.

Findings:

• Detailed embryological insights into the formation of a fused renal unit (cake kidney) with a solitary ureter are provided.
• The report delineates the clinical presentation and diagnostic pathway for this rare combination of anomalies.
• Effective management strategies tailored to this specific malformation are discussed.

Implications:

• This case contributes to the limited understanding of rare renal and urogenital malformations.
• It underscores the importance of comprehensive evaluation in patients with caudal regression syndrome for associated anomalies.
• The findings offer valuable information for clinicians managing complex pediatric urological conditions.
