To investigate the impact of hospital volume on short‐term outcomes after cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC).
We identified mRCC patients who underwent CN from 2006 to 2013 in the National Cancer Database. Annual hospital CN volume was categorized as high (top 20th percentile) and low. Multivariable logistic regressions were used to compare...
To evaluate the impact of hospital volume on outcomes of robot‐assisted partial nephrectomy (RAPN).
Materials and Methods
Patients with renal cell carcinoma who underwent RAPN between 2010 and 2013 were identified in the National Cancer Database. Hospital yearly RAPN volume was categorized into groups by sorting patients as closely as possible into five groups of equal size (quintiles):...
To assess whether discharging patients early after radical cystectomy (RC) is associated with an increased risk of readmission and post‐discharge complications.
Materials and Methods
The National Surgical Quality Improvement Program database was queried to identify patients who underwent an elective RC from 2012 to 2015. Patients were stratified into two groups: those with a length of...
This paper presents a framework for segmentation of renal parenchymal area from ultrasound images based on a 2-step level set method. We used distance regularized level set evolution method to partition the kidney boundary, followed by region-scalable fitting energy minimization method to segment the kidney collecting system, and determined renal parenchymal area by subtracting the area of the collecting...
Tamsulosin is associated with increased passage of ureteral stones in adults but its effectiveness in children is uncertain. We determined the association between tamsulosin and the spontaneous passage of ureteral stones in children.We performed a multi-institutional retrospective cohort study of patients 18 years or younger who presented between 2007 and 2012 with ureteral stones up to 10 mm and...
