Summary
Two patients spontaneously passed silicate stones, confirmed by infrared spectrophotometry. This study reviews 30 previously reported Japanese cases of silicate calculi.
Area of Science:
- Nephrology
- Mineralogy
Background:
- Silicate calculi are rare urinary tract stones.
- Understanding the composition of kidney stones is crucial for diagnosis and treatment.
Observation:
- Two patients, aged 53 and 55, presented with spontaneous passage of urinary stones.
- Infrared spectrophotometry analysis revealed the stones were primarily composed of silicate.
Findings:
- The patients had no known history of ingesting magnesium silicate, a potential source of silicate.
- A review of 30 previously reported cases of silicate calculi in Japanese literature was conducted.
Implications:
- This case series contributes to the limited literature on silicate urolithiasis.
- Further research may elucidate the etiology and optimal management of silicate stones.
