Multicenter Study Comparative StudyReassessment of prognostic heterogeneity of pT3 renal pelvic urothelial carcinoma: analysis in terms of proposed pT3 subclassification systems.
We determined whether the 3 pT3 subclassification systems reported by the Asan, Cornell and Nagoya groups provide an accurate estimation of patient prognosis. We also determined which subclassification is most predictive of the heterogeneous oncological outcomes of pT3 renal pelvic urothelial carcinoma. ⋯ The criteria of microscopic vs macroscopic parenchymal invasion and/or peripelvic fat invasion provide the most accurate differential classification of the prognostic heterogeneity of pT3 renal pelvic urothelial carcinoma. Further studies should be performed to determine the need to modify the current pT3 renal pelvic urothelial carcinoma staging system.

Multicenter Study Comparative StudyThe impact of seat belts and airbags on high grade renal injuries and nephrectomy rate in motor vehicle collisions.
Motor vehicle collisions are the most common cause of blunt genitourinary trauma. We compared renal injuries with no protective device to those with seat belts and/or airbags using NTDB. Our primary end point was a decrease in high grade (grades III-V) renal injuries with a secondary end point of a nephrectomy rate reduction. ⋯ Occupants of motor vehicle collisions with protective devices show decreased rates of high grade renal injury and nephrectomy. Reduction appears most pronounced with the combination of seat belts and airbags.
