title: Various urinary properties in bladder tumor patients.
abstract: Urinary electrolytes, pH, urea nitrogen, creatinine, uric acid and osmolarity were measured in patients with bladder tumors and compared with those of a control group. There were 41 bladder tumor patients ranging in age from 29 to 87 (average 64) years with a male:female ratio of 32:9. According to histopathological classification of the bladder tumors, there were 34 transitional cell carcinomas (TCC) (21 G1, 10 G2, 3 G3), four squamous cell carcinomas, two adenocarcinomas and one inverted papilloma. The control group comprised 29 patients ranging in age from 35 to 80 (average 63) years with a male:female ratio of 26:3. Four urine samples were collected from each patient: early morning on the day of admission, just after admission, early morning on the day of return to hospital after temporary discharge, immediately after return to hospital after temporary discharge. The results indicated that the urinary Ca2+ and uric acid values were significantly lower in the bladder tumor group than in the control group. The urinary pH tended to be somewhat higher than in the control group, and the pH values tended to be especially high in the TCC G3 patients. There were differences in the various urinary properties between the TCC G1 and G2 and the TCC G3 patients.
