Brush biopsy performed via a retrograde catheter improves yield, with a reported sensitivity of 91%, a specificity of 88%, and an 1. URINE TESTS 23 accuracy of 89%. Complications include ureteric bleeding and perforation Analysis • Urine must be sent for analysis as soon as possible after collection • Following centrifuge, the cell pellet obtained is divided between two slides • One is stained with Papanicolaou stain and the other with hematoxylin and eosin • Microscopic analysis is performed Interpretation Primary goals of VUC are to— • Recognize early flat lesions such as CIS before they invade • Detect the 10% of superficial lesions destined to invade Characteristically, TCC cells may appear singly or in small clusters, have large hyperchromatic nuclei with irregular, coarsely textured chromatin.

8 is suggestive of renal tubular acidosis (RTA) The normal renal response to acidemia is to— • Reabsorb all filtered bicarbonate • Increase hydrogen excretion primarily by enhancing the excretion of ammonium ions in urine Any inability of the renal tubules to perform these functions leads to a metabolic acidosis which typically— • Is a normal anion gap (hyperchloremic) metabolic acidosis • Occurs as a consequence of either net retention of hydrogen chloride or its equivalent (such as ammonium chloride) or the net loss of bicarbonate or its equivalent There are three major subgroups of RTA with different clinical characteristics: 1.

Since PSA increases with age, a single reference standard would appear inappropriate in men of all ages given that the clinical significance of CAP varies with increasing age. Moreover, though CAP is commoner with advancing age, there is a paradoxical gradual decrease in its clinical significance. Men of all ages do not have the same therapeutic aims. 1). Factors affecting serum PSA 1. Age Blood PSA concentration is dependent on patient age, and the increase in PSA with advancing age is attributable to a number of factors including— • Normal hyperplasia of the aging prostatic epithelial cells • A higher incidence of subclinical prostatitis • The growing prevalence of microscopic, but clinically insignificant prostate cancer • Areas of prostatic infarction • Increased leakage of PSA into the serum 2.
