Detritus (/ d ə ˈ t r aɪ t ə s /; adj. detrital / d ə ˈ t r aɪ t əl /) is particles of rock derived from pre-existing rock through weathering and erosion. [1] A fragment of detritus is called a clast. [2] Detrital particles can consist of lithic fragments (particles of recognisable rock
Hypocitraturia or low urinary-citrate excretion (variably defined as less than 320 mg/day) can be a contributing cause of kidney stones in up to 2/3 of cases. The protective role of citrate is linked to several mechanisms; citrate reduces urinary supersaturation of calcium salts by forming soluble complexes with calcium ions and by inhibiting ...
Urine pH may be monitored to help prevent the formation of kidney stones or to avoid side effects of some drugs, [68] such as high-dose methotrexate therapy, in which crystals that cause kidney damage can form if the urine is acidic. [69] If microscopy is performed, knowing the pH of the sample helps to identify any crystals that might be ...
Urinalysis - After the patient provides a urine specimen, it is sent to the lab for analysis using a variety of methods including urine dipstick testing and microscopic examination. Because the kidney is responsible for making urine , analyzing the urine directly can provide crucial data that can help the physician diagnose nephritic syndrome ...
Modern sealife aquariums often use the Berlin Method, which employs a piece of equipment called a protein skimmer, which produces air bubbles which the detritus adheres to and forces it outside the tank before it decomposes and also a highly porous type of natural rock called live rock where many benthos and bacteria live (hermatype which has ...
A urinalysis is helpful even when not showing any pathology, as this finding suggests an extrarenal etiology. Proteinuria and/or urinary sediment usually indicates the presence of glomerular disease. Hematuria may be caused by glomerular disease or by a disease along the urinary tract. [citation needed]
Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys.Because necrosis is often not present, the term acute tubular injury (ATI) is preferred by pathologists over the older name acute tubular necrosis (ATN).

A sample of urine sediment from a patient suffering from a urinary infection, it is possible to see leukocytes (small round and granular), erythrocytes (small round and biconcave) and epithelial cells (large and polyhedral). The test for leukocyte esterase is indicative and does not replace microscopic examination of urine.
