Urinary Crystals Identification and Analysis - StatPearls - NCBI Bookshelf
网页2024年7月27日 · Urine pH plays a key role in crystallization, as CaP, struvite, and ciprofloxacin crystals precipitate in alkaline urine. In contrast, uric acid, cystine, and other drug-induced crystals tend to precipitate in acidic urine. These characteristics assist clinicians in accurately identifying urinary crystals.
Differential identification of urine crystals with morphologic ...
网页2022年9月26日 · Five types of uric acid (UA) crystals are found in urine, amorphous UA, crystalline UA, anhydrous UA (uricite), UA monohydrate (UAM), and UA dihydrate (UAD). The formation of UA crystals depends on the UA concentration and acid pH (<5.5).

网页2022年8月10日 · Uric acid crystals invariably form in acidic urine, typically with a urine pH < 5.5. Uric acid is soluble in alkaline urine, preventing the precipitation of urate crystals. The inability of uric acid to crystallize at urine pH > 7.0 is the rationale for urinary alkalinization in patients at risk for acute uric acid nephropathy.
