Summary
An uncommon kidney anomaly, extra-renal location of the major renal calices, was found in 3% of adult kidneys. This condition, associated with abnormal blood vessels, can obstruct urine flow and cause retention.
Area of Science:
- Anatomical Pathology
- Urology
- Developmental Biology
Background:
- The renal calices are crucial structures for urine collection within the kidney.
- Anatomical variations can impact renal function and surgical approaches.
Purpose of the Study:
- To report the incidence and characteristics of extra-renal location of major renal calices.
- To investigate associated vascular anomalies and their clinical implications.
Main Methods:
- Examination of 300 adult kidneys obtained post-mortem.
- Detailed anatomical dissection and observation of renal hilus structures.
Main Results:
- Extra-renal location of major renal calices observed in 3 out of 300 kidneys (1%).
- Associated vascular variations in the renal hilus were noted in these cases.
- These anomalies presented a risk for impaired urinary outflow and urine retention.
Conclusions:
- Extra-renal major renal calices represent a rare developmental anomaly.
- Associated vascular variations may lead to significant urinary tract complications.
- Awareness of this anomaly is important for clinicians and anatomists.
