Results of a study analyzing global trends in mortality attributable to urolithiasis show that the rate declined over a recent 20-year period.

Other pipeline developments discussed include an implantable device for OAB treatment, a subcutaneous hypogonadism treatment, efficacy results for an HPV drug, and the status of a device-based BPH treatment.

Whether or not medical expulsive therapy (MET) is a sound recommendation for patients with kidney or ureteral stones is a matter of debate.

Patients undergoing ureteroscopy while remaining on anticoagulant therapy may be at increased risk for bleeding complications, including significant bleeding events and unplanned returns to the operating room, according to a retrospective study

Results from bench studies favor a new open-faced stone retrieval device (Dakota, Boston Scientific) for having greater versatility, efficacy, and durability compared with a competing product, and the in vitro performance of the new instrument is consistent with early clinical experience, says Roger L. Sur, MD.

A large new study provides more evidence that cholesterol drugs may lower kidney stone formation.

"Increasingly, urologists are faced with patients who cannot safely discontinue anticoagulation or antiplatelet medications, even in the face of an impending surgical procedure. This is a trend that is likely to continue into the foreseeable future," writes Brian R. Matlaga, MD, MPH.
