Urine cytology in patients with urinary tract calculosis.

Urinary cytological examination was performed on 375 patients suffering from urolithiasis at the Department of Urology. University School of Medical Sciences, Bydgoszcz between 01.01.1991 and 31.12.1992. 189 were female (mean age: 47.5 years), 186 were male (mean age: 53.5 years). 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.
