The examination of urine is an ancient medical procedure dating back thousands of years. Microscopic examination of cells in the urine is being done since the invention of microscope. Presently the cytological examination of urine or other fluid samples from the urinary tract is a routine non-invasive diagnostic procedure to detect cancer of the urinary tract, especially in patients with painless haematuria. It is also used in the follow-up of patients previously treated for bladder cancer to detect recurrence or a new primary. It is a highly specific method for the diagnosis of invasive and in situ urothelial carcinoma and high-grade papillary carcinoma. However, it is unreliable for the detection of low-grade papillary neoplasms. Malignant cytomorphological characteristics of the exfoliated cells in urine or bladder washing can facilitate the diagnosis of bladder cancer. The Paris System (TPS) Working Group has proposed. The Paris System (TPS) authorities have proposed a standard reporting stem which includes specified diagnostic categories and cytomorphologic criteria for diagnosis of High-grade Urothelial Carcinoma (HGUC).
