Microscopic Tubulovenous Communications in Nonneoplastic Kidneys: A Single-Center Case Series and Review of the Literature.

ABSTRACT:

Rationale & objective

Pathological connection between the kidney tubules and veins is known as a microscopic tubulovenous communication we refer to as a tubulovenous fistula (TVF). This finding has been reported in a few small case reports, but no systematic examination of cases across various clinical settings detailing their histologic spectrum and associated clinical/pathologic findings has been performed.

Study design

Case series and literature review.

Setting & participants

Nonneoplastic kidney pathology reports from an academic medical center (February 1, 1990, to February 1, 2024) were queried for mention of TVF. In total, 30,537 nonneoplastic kidney reports were queried, and 22 cases of TVF were identified.

Results
