Differences in Overall and Cancer-specific Survival of Patients Presenting With Chromophobe Versus Clear Cell Renal Cell Carcinoma: A Propensity Score Matched Analysis.

Objectives: To investigate prognostic parameters for the oncological outcome of patients treated for chromophobe renal cell carcinoma (chRCC) in comparison with patients treated for clear cell RCC (ccRCC) using propensity score matching for survival analysis.

Methods: From 1969 to 2009, we identified 1010 from 3567 patients with RCC. Survival was analyzed using Kaplan-Meier estimate for histological subtypes including 109 chRCC and 901 ccRCC.

Presentation, Management and Long-Term Outcome of Ureteropelvic Junction Obstruction in Duplex Kidneys.

Purpose: Ureteropelvic junction obstruction in association with a duplex collecting system is a rare but challenging upper urinary tract pathology. We report our 21-year experience with this anomaly in terms of presentation, diagnostic evaluation and management.

Materials And Methods: We retrospectively identified all patients with ureteropelvic junction obstruction in a duplex collecting system between 1991 and 2012.
