Ureteroscopic pneumatic lithotripsy (URS-PL) has a high success rate in treating unilateral distal-ureteral stones, a study found.

Urinary supersaturation of uric acid rises with BMI, which could explain why obese individuals have a higher incidence of kidney stones, a study indicates.

TOPIRAMATE (Topamax), a drug for epileptic seizures and migraine headaches, may cause systemic metabolic acidosis, lower urinary citrate excretion, and raise urinary pH if used long-term, data suggest. The side effects could significantly increase the likelihood of calcium phosphate stones, investigators warn.
