Glomerular polycystic kidney disease in a dog (blue merle collie)
Abstract:
Glomerular polycystic kidney disease was diagnosed in an 11 month old, female, Blue Merle Collie. Clinical signs (polyuria, polydipsia, vomiting, diarrhea, partial anorexia) and laboratory work (blood urea nitrogen, creatinine, serum phosphorus, specific gravity, proteinuria, nonregenerative anemia) indicated chronic renal failure.However, after the study of a biopsy specimen, a definitive diagnosis was reached and the prognosis was determined. Necropsy findings and histopathological studies revealed: presence of glomerular cysts, atrophy of glomerular tufts and sclerosis of the interstitial tissue.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
