Cylindroids in urine sediment microscopy: morphological features of mucus strands, differential diagnosis with casts, and clinical significance.
Cylindroids. Urine sediment microscopy.
Very long or short, delicate, colorless, ribbon-like formations consisting of mucin and mucus. They have indistinct longitudinal striation, often split at the ends into bundles of delicate fibers or sharply narrowed. A large number of cylindroids indicates inflammation of the urinary tract and, especially, the bladder.
