A case of renal arteriovenous fistula between
the main renal artery and interlobar vein diagnosed 25
years after percutaneous renal biopsy was presented. A
62-year-old female was referred to a urologist with dilatation
of the left renal pyelocalyceal system diagnosed after
abdominal ultrasonography, while intravenous urography
did not confirm that finding. Historically, she underwent
renal biopsy 25 years ago without any complication.
Her hypertension was well controlled during the last 10
years, although three antihypertensive drugs with occasional
additional diuretics were necessary during the last
6 months. Color Duplex Ultrasonography, arteriography
and Multi-Slice Computed Tomography revealed the presence
of renal arteriovenous fistula between the main renal
artery and interlobar vein, as well as severe dilatation of
all interlobar veins, renal, ovarian and adrenal vein on
the left side. Urological and vascular surgeons operated
to ligate the fistula and preserve the kidney. However, it
was not possible to reach the fistula inside the kidney and
nephrectomy was performed.
