In urinary schistosomiasis caused by Schistosoma haematobium, eggs are most commonly detected in which specimen?

Explanation:
Eggs of Schistosoma haematobium are released in urine because the adult worms reside in the bladder’s venous plexus and lay eggs that pass through the bladder wall into the lumen. This makes urine the specimen most likely to contain eggs, so microscopic examination of urine sediment is the standard diagnostic method for this species. Stools are used to detect eggs of intestinal schistosomes (like S. mansoni or S. japonicum), while blood or sputum are not reliable sources for detecting eggs of this urinary form.
