TREATMENT OPTIONS IN STRUVITE STONES
Urologic Clinics of North America, 1997Urinary calculi have plagued man over the centuries. The epidemiology and pathogenesis of infection have been studied. The curative treatment remains problematic. Without therapy, a vicious cycle of stone formation occurs. This results in renal damage and even death. Multimodality therapy is the key.

Seminars in nephrology, 1997
Although calcium oxalate stones are the most common type of calculi found in the United States, struvite or infection stones are quite common and generally pose a difficult treatment dilemma. The presence of urinary infection with a urease-producing organism is necessary for these stones to form.

Etiopathogenesis of Canine Struvite Urolithiasis
Veterinary Clinics of North America: Small Animal Practice, 1986Urine must be oversaturated with magnesium ammonium phosphate for struvite uroliths to form. Oversaturation of urine with magnesium ammonium phosphate may be associated with several factors, including urinary tract infections with urease-producing microbes, alkaline urine, diet, and genetic predisposition.

Struvite Precipitation by Trypanosoma cruzi
The Journal of Parasitology, 1987It has been previously reported that some microorganisms in culture possess the capacity to generate exocellular mineral crystals. Some species of bacteria are able to produce crystals such as aragonite, calcite, apatite, stroncianite, and struvite (Greenfield, 1963, Annals of the New York Academy of Science 109: 23-45; Ennever et al., 1974, Journal of

At a meeting of the Cambridge Philosophical Society on May 20th, Mr. Robinson read a preliminary paper "On the formation of Struvite by Micro-organisms.""The author had observed the formation of fine well-formed crystals in many tubes of nutrient gelatin and agar-agar, in which he was growing pure cultivations of various micro-organisms."

Medical dissolution of feline struvite urocystoliths
Journal of the American Veterinary Medical Association, 1990Summary The efficacy of a diet designed to facilitate dissolution of feline magnesium ammonium phosphate (struvite) uroliths was evaluated in 30 cases of urocystoliths, involving 27 cats. The number of urocystoliths per cat varied from 1 to 5. In 20 cases of urolithiasis, sterile struvite uroliths dissolved in a mean of 36 days after initiation of ...

Primary Dissolution Therapy of Struvite Calculi
Journal of Urology, 1984Percutaneous nephrostomy and hemiacidrin were used as primary treatment of magnesium ammonium phosphate calculi in 32 surgical candidates. Of 28 patients who actually received hemiacidrin 24 (85 per cent) had successful treatment (no surgery necessary), including 19 (68 per cent) who had total stone dissolution. There were no significant complications.

Aufgrund hoher Preise und strenger Restriktionen bei Stickstoff- und Phosphordüngern rücken Mineralien in den Fokus, die aus wirtschaftlichen Gründen bislang nur ein Schattendasein geführt haben. Eines davon ist Struvit, auch bekannt als Magnesium-Ammonium-Phosphat (MAP).

Bacterial formation of struvite
Geomicrobiology Journal, 1983We studied the formation of exocellular precipitates of struvite (Mg NH4PO4.6H2O) by 96 kinds of calcite‐pro‐ducing bacterial strains isolated from soil. We also studied the influence of calcium ions on struvite precipitation. The number of strains producing struvite was 20. Only four consistently formed large amounts.

Looking Beyond Struvite for P-Recovery
Environmental Science & Technology, 2013) and could potentially be used asa slow-release fertilizer. If the economic and life cycle costs aretaken into account, however, it becomes clear that phosphaterecovery as struvite is likely not the best approach, for thefollowing reasons: (1) production of P-mineral with a highcontent of struvite from real wastewater is a difficult and costlyprocess ...
