Résumé
The dipstick testing, microscopic examination of urine and urine cytology were performed for inhabitants from two rural villages [El Shobak El Sharki, V.I and El Katta, V.2] in Giza G. The proliferating cell nuclear antigen [PCNA] and Schistosoma haematobium antigen were done by immuno-histochemical stain to confirm diagnosis. Also, they were subjected to medical questionnaire, clinical examination, ultra-sonography of kidneys and urinary tract. The results showed that V.2 had higher percentage of haematuria, proteinuria, glucosuria and lower urinary tract infection than V.I. Crystaluria was higher in V.I. Sensitivity of dipstick testing compared to microscopic examination was 26.6%, and specificity was 78.7%. Lower urinary tract infection cytologically detected was 44.2% sensitivity and 62.5% specificity compared to pyuria detected by microscopic examination of urine. Among those suffering variable urinary abnormalities, schistosome antigen was not detected in any fixed urine samples in comparison to corresponding confirmed positive controls. Urine cytology detected urinary tract infection, Crystaluria, dysplasia and atypia, squamous metaplasia and transitional cell carcinoma [TCC]. PCNA positivity was found in TCC [100%], dysplasia [50%] and squamous metaplasia [28.6%]. So, microscopic examination of urine proved valuable for tract abnormalities as pyuria, haematuria and crystaluria. Also, urine cytology is a must for malignancy of urinary tract especially in adult males
