title: Urinary excretion of sialic acid in patients with superficial bladder tumors.
abstract: Urinary total sialic acid/creatinine (TSA/Cr) ratio was determined in 73 patients with superficial bladder tumors and 34 healthy volunteers. The mean TSA/Cr value in the tumor group was higher than the control group (P < 0.001) and this difference was significant. Comparing the urinary TSA/Cr ratio of Tl, Ta, grade I-II, grade III, single, multiple, primary and recurrent tumors, with the control group revealed significant results (P < 0.001). Therefore the urinary TSA/Cr ratio determination in the follow-up of these patients may be used as a non-invasive procedure.
