Macroscopic amoxicillin crystalluria

Struvite Crystalluria: Three Cases

The following cases demonstrate the importance of evaluating the total clinical picture and explore how preparing dry-mount urine sediment cytology can maximize the potential of in-house urinalysis. Dry-mount cytology is a quick and relatively easy technique useful not only for evaluating conditions such as urinary tract infection (UTI) or neoplasia but when seeking a pathologist’s second opini...

Crystalluria in a dog

Amoxycillin, a rare but possible cause of crystalluria.

Crystalluria caused by amoxycillin is a rare event that may be asymptomatic or may have severe renal implications. In January 2002 a urine sample from a 64-year-old woman which contained a large amount of unusual crystals was referred to us. Macroscopically the urine was normal. By dipstick, pH was 5.5, relative density 1.030, and albumin" haemoglobin and leukocyte esterase were negative. Howev...

Acute renal failure due to sulphadiazine crystalluria in AIDS patients.

We report two AIDS patients who developed acute renal failure while receiving sulphadiazine for cerebral toxoplasmosis. Renal ultrasound revealed diffuse bilateral echogenic shadowing material. 'Sheaves of wheat' crystals, typical of sulphadiazine crystalluria, were present in the urine. One patient required a percutaneous nephrostomy. Hydration and urine alkalinisation resulted in rapid improv...

Amoxicillin clavulanate vs. amoxicillin for treatment of UTI

Dear Editor, I note in the “Antibiotics: Choices for Common Infections” booklet provided with the August 2013 edition of Best Practice Journal, that amoxicillin with clavulanic acid is recommended as an alternative agent for treating UTI in children. I would be interested in understanding the rationale for this recommendation, given the poor oral absorption and urinary excretion of clavulanic a...
