Which finding in urine is most closely associated with Trichomonas vaginitis?

The finding most closely associated is seeing the Trichomonas vaginitis organism in the urine sediment. Trichomonas vaginalis is a flagellated protozoan that can be shed into urine, and a wet mount or examined sediment may reveal motile trophozoites—the pear-shaped organisms with flagella moving visibly under microscopy. This direct visualization is specific for this infection. In contrast, oval fat bodies signal lipiduria from nephrotic processes, nitrite-positive bacteria with white cells point to a bacterial UTI, and uric acid crystals relate to crystals from stones or gout—none of which indicate Trichomonas vaginitis.
