Summary
Renal angiomas on papillae tips caused severe hematuria, necessitating transfusions. Diagnosis was confirmed via intraoperative nephroscopy and histology, despite negative radiological findings.
Area of Science:
- Nephrology
- Urology
- Vascular Malformations
Background:
- Renal angiomas are rare vascular malformations.
- Papillary location can complicate diagnosis and treatment.
- Severe hematuria is a potential, though uncommon, presentation.
Observation:
- A patient presented with severe, life-threatening hematuria.
- The bleeding source was suspected to be within the kidney.
- Initial radiological investigations, including arteriography, were inconclusive.
Findings:
- Intraoperative nephroscopy identified angiomas at the papillary tips.
- Histological examination confirmed the diagnosis of renal angiomas.
- The precise location on the papillae was crucial for diagnosis.
Implications:
- Highlights the importance of nephroscopy for diagnosing obscure renal bleeding.
- Suggests that papillary renal angiomas should be considered in cases of severe hematuria.
- Emphasizes the role of histology in definitive diagnosis of vascular lesions.
