Renal vein thrombosis is caused by all except



A Renal cell carcinoma

B Rapid correction of dehydration

C Trauma

D Nephrotic syndrome

Ans. B Rapid correction of dehydration (REF. CAMPBELL UROLOGY 9TH EDN PG 765)

a. In patients who are nephrotic, the most common underlying nephropathy associated with renal vein thrombosis (RVT) is membranous nephropathy.

b. The tumor association for renal vein thrombosis (RVT) is renal cell carcinoma.

c. However, most cases of membranous nephropathy are idiopathic.

d. Renal vein thrombosis (RVT) also may be the result of nephrotic syndrome from membranoproliferative glomerulonephritis, minimal change disease, rapidly progressive glomerulonephritis, amyloid, focal sclerosis, or lupus nephritis.

e. Renal vein thrombosis (RVT) is more common in patients with primary rather than secondary nephropathy.

f. Findings relative to the causative disease may be present (eg, systemic lupus erythematosus [SLE]/antiphospholipid antibody syndrome, cancer).

g. Initially, nephrotic syndrome was believed to be a consequence of renal vein thrombosis (RVT). However, this presumed sequence was incorrect.

h. Renal vein thrombosis (RVT) in the absence of nephrotic syndrome has been reported in the surgical literature.

i. Nephrotic patients with renal vein thrombosis (RVT) who have undergone histologic evaluation show evidence of an identifiable glomerulopathy.

j. Renal vein thrombosis (RVT) is known to occur after the onset of nephrotic syndrome. Thus, nephrotic syndrome is not a direct result of renal vein thrombosis (RVT) but rather leads to renal vein thrombosis (RVT).

k. Renal vein thrombosis (RVT) is an uncommon but definite problem in neonates. A possible association exists between renal vein thrombosis (RVT) and the factor V Leiden mutation in this age group.

l. Other diseases or situations that have been associated with renal vein thrombosis (RVT) include antithrombin III deficiency, protein C or S deficiency, antiphospholipid antibody syndrome, pregnancy or estrogen therapy (all hypercoagulable states),
