Catheter Encrustation by Struvite

British Journal of Urology, 1983
SUMMARY— Encrusted catheters from 10 female patients were the source of 26 samples of deposits which were examined by X‐ray diffraction. Four different types of catheter were represented. The only detectable compound in all of the samples was ammonium magnesium orthophosphate hexahydrate (NH ...

Glycosaminoglycans and struvite calculi

World Journal of Urology, 1994
Glycosaminoglycans (GAGs) are suspended in urine and are present on tissue surfaces in the urinary tract. Consequently, they have the potential to influence any pathological disorder in this environment, including urinary tract infections by Proteus mirabilis and struvite (NH4MgPO4.6H2(0)) urolithiasis.

Struvite Stones

Nephron, 1987
Struvite stones constitute only about 2–3% of the stones reaching the laboratory for analysis, but the clinical problems they create including sepsis and even renal demise are greater than with any other stone type. This article reviews the evidence that bacterial urease, usually from a Proteus species, is responsible for the chemical changes in urine ...

Struvite and Prebiotic Phosphorylation

Science, 1973
Struvite, MgNH 4 PO 4 ⋅6H 2 O, rather than apatite or amorphous calcium phosphate is precipitated when phosphate is added to seawater containing more than 0.01 M NH 4 + ions.

Comparison of Struvite and K-Struvite for Pb and Cr Immobilisation in Contaminated Soil

SSRN Electronic Journal, 2022
Struvite is a value-added by-product recovered from phosphorus-rich wastewater treatment by adding magnesium. Struvite is mainly used as slow-release fertilisers containing phosphate that can form insoluble salts with certain heavy metals. Hence, struvite may have potential application as a phosphate remediation agent for the immobilisation of heavy ...

Struvite formation, control and recovery

Water Research, 2002
Recent legislation on the removal of nutrients from wastewater has led to a number of operation problems with struvite scaling. Struvite is MgNH4PO4 x 6H2O and this paper reviews the formation, control and recovery of struvite from primarily municipal wastewater and other waste streams.
