Abstract
Urinary cytological examination was performed on 375 patients suffering from urolithiasis at the Department of Urology.

We found dysplastic cells in urinary sediments in 25.3% of patients before therapy and in 5.3% of patients after conservative or traditional operation and interventional therapy (ESWL. PCNL). Degenerated cells were found in 72% of patients before therapy and in 30.4% after therapy only. In our group neoplasmatical cells were not found. Inflammatory background was found in 44.5% before and in 21.9% after therapy, pyuria in 19.7% and 0.8% respectively. In urinary sediments we found concrements in 24% of patients before and 7.7% after therapy. However, 20 (51.3%) of 39 patients after interventional therapy (ESWL, PCNL) had concrements in urinary sediments. In conclusion, no abnormality was seen in 85.1% before therapy and in 31.2% after therapy. The significance of cytological examination in management of calculous diseases was discussed.
