Renal hypoplasia
Renal hypoplasia (ORPHA:93101, ICD-10 Q60.3-Q60.5) is a congenital malformation of abnormally small kidneys with normal corticomedullary differentiation and reduced nephron number, caused by developmental gene mutations (HNF1B, PAX2, PBX1) or environmental factors, risking hypertension and chronic kidney disease.
Renal replacement therapy
Renal replacement therapy (RRT, kidney replacement therapy) covers hemodialysis, peritoneal dialysis, and kidney transplant for severe acute kidney injury or stage 5 CKD, with conservative management as a non-dialysis option; dialysis typically starts at eGFR 5-7 ml/min/1.73 m2 or on emergency indications.
Uremia
Uremia (urémie): clinical syndrome of uremic toxin retention in blood from kidney failure, named 1847; symptoms include pericarditis and encephalopathy; treated by dialysis since Kolff's 1945 success.
Urinary cast
Urinary casts (casts in the urine) are tube-shaped particles formed from Tamm-Horsfall protein in kidney tubules, seen on urinalysis microscopy. Hyaline casts are normal; RBC casts indicate glomerulonephritis, granular casts acute tubular necrosis.
