Crossed ureteral ectopia with solitary kidney
Urologia Internationalis
|January 1, 1980
Summary
This case study presents a rare instance of crossed ureteral ectopia in a solitary kidney found in a 73-year-old male patient. The study details the unique presentation and discusses the embryological origins of this congenital anomaly.
Area of Science:
- Urology
- Developmental Biology
- Medical Case Reports
Background:
- Congenital anomalies of the kidney and urinary tract (CAKUT) represent a spectrum of developmental abnormalities.
- Solitary kidney, a condition where only one kidney is present, can be associated with other urological malformations.
- Crossed ectopia, where a kidney is located on the contralateral side of the body, is a rare CAKUT.
Observation:
- A 73-year-old male patient presented with a unique urinary tract malformation.
- The patient possessed a solitary kidney that was anatomically normal in position and vascularization.
- A second, blind ureter was observed on the same side (homolateral) as the normally situated kidney.
Findings:
- The observed anatomy was diagnosed as crossed ureteral ectopia occurring in a solitary kidney.
- This specific presentation suggests a complex embryological event leading to the malformation.
- The normally situated and vascularized kidney with a homolateral blind ureter is a key diagnostic feature.
Implications:
- This case contributes to the understanding of rare congenital urinary tract malformations.
- Further research into the embryogenesis of crossed ectopia with solitary kidneys may reveal new insights.
- Such cases highlight the importance of thorough diagnostic evaluation in patients with congenital anomalies.
