    Summary
    This summary is machine-generated.

    Idiopathic renal vein varicosities are rare venous malformations. Diagnosis relies on imaging, with surgical intervention often curative for this cause of hematuria and flank pain.

    Area of Science:

    • Urology
    • Vascular Medicine
    • Radiology

    Background:

    • Pelviureteric varices are known complications of renal vein thrombosis.
    • Idiopathic renal vein varicosities are exceptionally rare, with only 10 previous reports.

    Observation:

    • This study presents 3 new cases of idiopathic renal vein varicosities.
    • Common symptoms include hematuria (two-thirds of patients) and flank pain (one-fourth).
    • Associated findings include saphenous vein varicosities (one-third of patients).

    Findings:

    • Pyelography reveals characteristic scalloped deformities of the upper ureter and renal pelvis.
    • These deformities manifest as displacement and intraluminal filling defects.
    • Excretory urography can suggest the diagnosis, but venography is definitive.

    Implications:

    • Surgical excision and ligation of the affected veins offer a curative treatment.
    • Nephrectomy may be necessary in rare cases of life-threatening hemorrhage.
    • Understanding these rare vascular anomalies is crucial for accurate diagnosis and management.
