PYELITIS. An abscess may develop in the pelvis of the kidney instead of in thekidney proper. The causes of this are the same as for suppurative nephri-tis, though perhaps calculi will more frequently produce an abscess herethan in the kidney proper. The symptoms do not differ from those ofsuppurative nephritis, and the exact location of the abscess can only bedetermined by microscopical examination of the urine (Fig. 112). In an acute suppurative pyelitis, red blood-corpuscles are always pres-ent in moderate or even large numbers, and pus-corpuscles are extremelynumerous. The diagnosis can be made from the cuboidal and irregularpelvic epithelia, which in these cases are abundant, and may be found ingroups. In such abscesses epithelia from all the different layers of thepelvis will be present. These epithelia may vary considerably in size, anda few may be even as large as those from the middle layers of the bladder.There should, however, be no difficulty in diagnosing them, since these

DISEASES OF THE KIDNEY AND PELVIS. 225 large epithelia are irregular, angular, lenticular, or pear-shaped. Connec-tive-tissue shreds are numerous, and without them no such diagnosis mustbe made. In all cases epithelia from the ureter, showing a secondary inflamma-tion, are quite abundant, and in many of them endogeneous new-forma-tions of pus-corpuscles will be found. Epithelia from the convolutedtubules of the kidney need not necessarily be present in acute cases, butsooner or later a moderate number, the indication of an accompanyingnephritis, are seen; here, too, endogenous new-formations can appear.Very soon
