[Abstract]:Objective: to collect 195 consecutive morning urine specimens and fresh urine specimens for three days of suspected urothelial carcinoma, to examine the exfoliative cytology, to compare the positive rate of two urine specimens and to determine the positive rate of each grade urothelial carcinoma, to explore the diagnostic efficiency of different urine specimens, and to diagnose early clinical diagnosis. Urothelial carcinoma provides reliable examination methods and theoretical basis.
Methods: in the Department of Urology, Affiliated Hospital of Qinghai University, 195 cases of suspected urothelial carcinoma were collected for two years in October ~2013, October 2011, with hematuria, 119 males and 76 females. The age was 22~87 years old. The average age was (45.26 + 18.54) years old. Every patient was examined for the morning urine specimens and fresh urine specimens for three days, and the tissue specimens were excised by operation. Pathological diagnosis of biopsy results under cystoscopy was used as control, divided into low malignancy tendency urothelial papillary tumor, low grade urothelial carcinoma and high grade urothelial carcinoma three [1]. through histopathological diagnosis in 98 cases of urothelial carcinoma, 68 male, 30 female, age 25~84, average (54.39 + 14.57) years, 11 low There were 39 cases of low grade urothelial carcinoma and 48 cases of high grade urothelial carcinoma. The positive rates of urothelial carcinoma were detected in two urine samples and the positive rates of urinary tract carcinoma were detected. The diagnostic efficiency of different urine specimens was discussed, and the data were statistically analyzed and counted. X2 test was used to get P value and whether there was statistical significance.
Results: 1.. The cytological examination of two specimens on three days was compared.
The positive rate in the three day morning urine group was 32.65%, 31.63%, 39.80%, the positive rate of fresh urine group was 59.18%, 57.14%, 64.29%. The positive rate of fresh urine group was higher than that in the morning urine group. The positive rate of the first day of the urine was X2 test (X2=13.89, P=0.00020.01), and there were significant differences; there were significant differences on second days (X2=12.92, P=0.00030.01), third days (X2=11.77, P=0.000). 60.01), there were significant differences. At the same time, the results were compared between three days in the morning urine group (X2=2.171, P=0.3380.05), and there was no statistical difference. There was no statistical difference between the fresh urine group (X2=5.062, P=0.0790.05).
2. the positive rates of two kinds of specimens for various grades of urothelial carcinoma were compared.
The positive rate in the first day morning urine group was 1.02%, 11.22%, 20.41%, the fresh urine group was 4.08%, 24.49%, 30.61% respectively. The positive rate of the fresh urine group was higher than the morning urine samples (X2=15.26, P=0.0090.01), and there were significant differences. Second days morning urine group were 0%, 10.20%, 21.43%, respectively, 2.04%, 24.49%, 30.61%, respectively, fresh urine group, respectively, (X2=15 .81, P=0.0070.01), there were significant differences. Third days of morning urine group were 3.06%, 13.27%, 23.47%, fresh urine group was 4.08%, 27.55%, 32.65%, (X2=13.72, P=0.0180.05), with statistical significance. At the same time, the morning urine group was compared between three days, (X2=6.346, P=0.7850.05), no statistical difference. The fresh urine group was compared between three days (X2=11.12, P=0.3480.05), no unification. Study differences.
3. the diagnostic efficiency of two kinds of urine specimens for urothelial carcinoma:
The sensitivity, specificity, false negative rate and false positive rate of morning urine specimens were 39.80%, 36.08%, 60.20%, 63.92% respectively. The results of four indexes of fresh urine specimens were 64.29%, 60.82%, 35.71%, 39.18%, and two, 39.18% and two, respectively, and there were significant differences in P values.
Conclusion: 1. the positive rate of urothelial carcinoma detected by exfoliative cytology in fresh urine specimens is higher than that in morning urine samples.
2. the positive rate of the fresh urine specimens and the morning urine specimens for three days was not too large. The sensitivity and specificity of the fresh urine specimens were higher than those in the morning urine samples. The false positive rate and false negative rate were lower than those of the morning urine specimens.
3. the positive rate of cytological examination of fresh urine specimens was higher than that of morning urine samples for all levels of urothelial carcinoma.
The higher the grade of 4. urothelial carcinoma, the higher the positive rate of the exfoliative cytology examination of the morning urine specimen and the fresh urine specimen, and the positive rate of the high grade urothelial carcinoma detected by the fresh urine specimen is higher than that of the morning urine specimen.
The early diagnostic value of exfoliative cytology of 5. fresh urine specimens is higher than that of early morning urine specimens. In clinical practice, we collect more fresh urine samples in the detection and diagnosis of urothelial carcinoma.
