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.

Comparative StudyFeasibility of integrating research data collection into routine clinical practice using the electronic health record.
The electronic health record is becoming central to routine medical practice and has the potential to facilitate large scale clinical research. We evaluated the completeness and accuracy of data collection using designated research fields integrated into a semistructured clinical note. We hypothesized that prospective research data collection as part of routine clinical charting is feasible, with a high rate of utilization (greater than 80%) and accuracy (kappa greater than 0.80). ⋯ Integrating research fields into routine clinical practice is feasible by using semistructured clinical templates within an electronic health record. High completion and accuracy rates were captured from a variety of fields within a hydronephrosis template.

Elevated serum IgE may be associated with development of ketamine cystitis.
Previous studies revealed bladder mast cell and eosinophil cell infiltration in patients with ketamine cystitis. Due to possible hypersensitivity in those with this condition we investigated the association of serum Ig, histology findings and symptoms in patients with ketamine cystitis. ⋯ Patients with ketamine cystitis had higher serum IgE than patients with interstitial cystitis/bladder pain syndrome or acute bacterial cystitis, or controls. Serum IgE and the severity of eosinophil infiltration were associated with bladder pain severity and small maximal bladder capacity.

Epididymitis: a 21-year retrospective review of presentations to an outpatient urology clinic.
We describe patient characteristics and age distribution of epididymitis in an outpatient pediatric urology referral practice during a 21-year period. ⋯ The majority of cases of epididymitis occur around the time of puberty in early adolescence, with relatively few cases occurring during infancy. Recurrent episodes of epididymitis are more common than previously reported and may affect as many as a fourth of all boys with acute epididymitis.
