Renal-vein thrombosis is the formation of a blood clot in the
renal vein; the clinical presentation varies with the degree and speed of
venous occlusion. Renal vein thrombosis can sometime remain asymptomatic;
whereas, some patients might complain of nonspecific symptoms for instance nausea,
vomiting and weakness (Jou, Jong, Hsieh & Kang, 2014). Other specific
symptoms in severe cases include upper abdominal and flank pain, offensive
smelling urine, fever or haematuria. Additionally, scrotal pain in male caused
by thrombosis induced varicocele (Yildiz, Nieuwenhove, Doyen & Tombi, 2016).
Although, this patient did complain of flank pain and nausea, no other clinical
manifestation strongly suggested renal vein-thrombosis.
