Bladder washings provide the highest cellularity for urine cytology because the saline irrigation dislodges a large number of urothelial cells from the bladder lining, including those from suspicious areas. This technique yields well-preserved cells in clusters and fragments, offering better architectural assessment than voided urine. However, it is invasive and requires catheterization. Other methods like voided urine are non-invasive but have lower cellularity and more degenerative changes, while catheterized urine offers intermediate cellularity.
