Renal disorders in lambs may be congenital, infectious, toxic, immunologically mediated or secondary to urethral obstruction. Congenital abnormalities are uncommon. Kidney infections often are only one aspect of more widespread diseases, for example, tick pyaemia or salmonellosis. Toxic diseases, which affect mainly the renal tubules, may be caused by bacterial, chemical or plant toxins, although in lamb nephrosis the cause is unknown. Immunecomplex glomerulonephritis is uncommon, and one form, mesangiocapillary glomerulonephritis of Finnish landrace lambs, is under genetic control. Urolithiasis may have secondary effects on the kidneys.

A cystadenoma or a cystadenocarcinoma arising from the renal pelvis is a rare neoplasma and, so far as is known, only two cases have been reported in the literature (Arcadi, 1956, and Ross, 1985). Discussed herein is a case of a 63-year-old woman who developed a mucinous nephrosis, due to a marked retention of mucin produced by a tumor. The ureter as well was found to be involved. The histogenesis of an adenocarcinoma, which includes a cystadenoma and a cystadenocarcinoma, most likely is due to a glandular metaplasia, associated with urolithiasis and pyelonephritis. In this specific case, the patient revealed a history, fifteen years earlier, of renal calculi and pyelonephritis.

Kidneys from broiler chicks receiving 300 micrograms of oosporein K salt per gram of feed continuously from 0 to 21 days of age were examined by light and electron microscopy. Chicks that died at 3 days had nephrosis of initial proximal tubular segments with an early pyogranulomatous interstitial response. Macula densa cells had cytoplasmic accumulations of periodic-acid-Schiff-positive granules. Kidneys from chicks surviving 21 days had hypercellular or atrophic glomeruli and hyperplastic dilated proximal tubules. Centrilobular distal tubules were dilated and filled with hyaline basophilic casts. Interstitial fibrosis was prominent in cortical and medullary zones. These findings indicate that oral oosporein is a severe nephrotoxin which can cause visceral urate deposition and severe nephrosis of initial proximal tubular segments. The histopathology of this mycotoxicosis was compared with those of infectious-bronchitis-induced nephrosis and avian urolithiasis syndrome.

Ultrasonography is a helpful diagnostic tool in cattle with urinary tract disorders. It can be used to diagnose pyelonephritis, urolithiasis, hydronephrosis, renal cysts, renal tumors, amyloidosis, cystitis, bladder paralysis, bladder rupture, bladder neoplasms, and, occasionally, nephrosis, glomerulonephritis, and embolic nephritis. This article describes the anatomy, scanning technique, indications, limitations, normal and pathologic sonographic appearance of the bovine urinary tract. References from horses and humans are included, especially when the sonographic findings in these species may complement the understanding of similar diseases reported in cattle.

We report a case of bilateral renal calculi in a 1-year-old female with adenine phosphoribosyl transferase (APRT) partial deficiency. She initially visited another institution with high fever as the major complaint. Computed tomography revealed a bilateral renal stone and left hydro nephrosis. In the urine, there were 2, 8-dihydroxyadenine (DHA) crystals. An analysis of the APRT gene revealed the APRT deficiency and the genotype to be APRT*J/APRT*Q0. We performed extracorporeal shock wave lithotripsy (ESWL) under general anesthesia, and as dissolution therapy we administered Meylon through the nephrostomy and citric acid orally. The stone disappeared from her kidney. The analysis of the stone fragments revealed 2,8- dihydroxyadenine (DHA) urolithiasis.
