This document discusses the approach to hematuria in children. It begins by defining hematuria and describing different types. It then outlines the most common etiologies of glomerular and non-glomerular hematuria. The document emphasizes taking a thorough history and physical exam. It recommends investigations including urine analysis, blood work, imaging and potentially renal biopsy. Based on the cause, management may include reassurance, antibiotics, supportive care, monitoring, correcting complications, addressing underlying issues like calculi, or dialysis/transplantation for end stage renal disease.

6. Introduction
 Hematuria means blood in urine. Which can be either macroscopic or microscopic.
 Gross or Macroscopic hematuria can be seen by naked eyes while Microscopic hematuria are
detected only in urine microscopy.
 Microscopic hematuria is defined as the presence of >5 RBC per HPF in a centrifuged sample.
 Persistent hematuria is defined as presence of microscopic hematuria in >2 samples over next
2-3 wks.

F>M – SLE Nephritis
M>F – X linked form of Alport syndrome
 Discoloration of Urine
Dark yellow – Normal concentrated urine
Dark brown or black – Bile pigments, Homogentistic acid, melanin, tyrosinosis, methemoglobinemia
Cola coloured – Glomerular hematuria
Red or Pink urine – Extraglomerular hematuria, haemoglobin, myoglobin, porphyrins, chloroquine,
beets, blackberries, rifampicin, red dyes in food, urates.

11. History
 Characteristics of Urine :
 Amount of urine : Reduced in AGN, ARF
 Clots in urine : Extraglomerular
 Increased freqency , dysuria, recent enuresis : UTI
 Frothy urine : proteinuria seen in glomerular disease
 Timing :
Hematuria in initial stream – Urethra
Hematuria in terminal stream – Bladder

hypercalciuria
 Calculi : Plenty of water
 ESRD : Dialysis, Renal transplantation
