INTRODUCTION: In @entity1 with normal estimated renal function before robot-assisted partial nephrectomy (RPN), there is still a risk for de Novo @entity740 ( @entity740 ). We assessed the role of dipstick spot @entity644 in risk stratifying @entity1 for @entity740 progression. MATERIALS AND METHODS: From our prospectively maintained, institutional review board-approved database of @entity1 undergoing RPN, we queried those with estimated glomerular filtration rate (eGFR) >60 and bilateral functional units. We assessed @entity644 through dipstick (trace or above) on voided urine in preoperative urologic appointment <3 weeks before RPN. Proteinuric @entity1 were compared with the remainder of the cohort with parametric comparisons for continuous and chi-squared analysis for categoric variables. Multivariate logistic regression analyses were performed assessing the risk of de Novo @entity740 stage III development, estimated by the @entity740 -EPI equation. RESULTS: We found 269 @entity1 with eGFR >60 preoperatively, of whom 57 (21%) had @entity644 preoperatively. In univariate analysis, these @entity1 were more likely to be @entity6 (p   =   0.023) and to be on an @entity7774 converting enzyme inhibitor or angiotensin receptor blocker (p   =   0.001) but had similar age (p   =   0.13), body-mass index (p   =   0.09), and @entity5 size (p   =   0.56) with similar rates of @entity101 (p   =   0.07). At a median 16 months, controlling for confounding variables, preoperative @entity644 on urinary dipstick was associated with a 2.3* (95% confidence interval 1.03-4.95) increased risk of de Novo @entity740 stage III progression. CONCLUSIONS: @entity1 with @entity644 preoperatively, despite a normal eGFR, likely have @entity66 . These @entity1 should be counseled preoperatively that they have a higher risk of @entity740 progression following RPN.
