Patient's question:
Son is four years old, the urine test results are all normal except for the trace of blood in the urine test, what does it mean?Doctor's answer:
Hematuria in over 95% of cases is caused by diseases of the urinary system, with the most common being glomerular diseases (acute nephritis, rapidly progressive nephritis, membranoproliferative nephritis, mesangial proliferative nephritis, focal glomerular sclerosis, etc.), renal cysts, stones (kidney, ureter, bladder, urethral stones), benign prostatic hyperplasia, urinary tract infections (tuberculosis, pyelonephritis, cystitis, urethritis, prostatitis), and tumors (kidney, ureter, bladder, prostate tumors). Other conditions such as coagulation disorders (idiopathic or drug-induced thrombocytopenia, hemophilia, scurvy, etc.) and systemic diseases (aplastic anemia, leukemia, systemic lupus erythematosus, dermatomyositis, leptospirosis, hemorrhagic fever, etc.) can also cause hematuria.
