Comparative Study
Endoscopic-guided versus fluoroscopic-guided renal access for percutaneous nephrolithotomy: a comparative analysis.
To evaluate the intraoperative outcomes of percutaneous renal access using fluoroscopic-guided access (FGA) vs endoscopic-guided access (EGA). ⋯ EGA is safe and effective and leads to decreased fluoroscopy time, decreased need for multiple accesses, and decreased risk of early termination of the procedure or need for secondary procedures.

Randomized Controlled Trial
Fenoldopam and renal function after partial nephrectomy in a solitary kidney: a randomized, blinded trial.
To test the hypothesis that fenoldopam administration ameliorates ischemic injury, preserving the glomerular filtration rate and serum creatinine postoperatively after partial nephrectomy in patients with a solitary kidney. ⋯ Fenoldopam administration did not preserve renal function in the clinical setting of renal ischemia during solitary partial nephrectomy, as evidenced by changes in the glomerular filtration rate or serum creatinine.

To determine the associations between the pretreatment characteristics and treatment selection in patients presenting with clinical stage I renal masses. ⋯ Pretreatment characteristics associated with treatment type in our series, including the presence of a solitary kidney and anatomic complexity, are poorly captured using administrative and registry data. Observational studies investigating the variations in practice patterns for stage I renal masses require improved integration of clinical and tumor characteristics to reduce selection biases.

To ascertain the reliability of low-dose computed tomography (CT) compared with standard CT in the determination of stone size, density, and skin-to-stone distance (SSD). ⋯ No significant difference was found in the measurement of stone size, Hounsfield units, or SSD between the low-dose and conventional-dose CT scans. However, the low-dose CT scans resulted in a marked reduction in the radiation dose to the patient.

Transurethral insertion of foreign bodies into the urinary bladder is uncommon in children. We report an 11-year-old boy who presented with hematuria and difficulty voiding secondary to numerous magnetic beads lodged in the urinary bladder and posterior urethra.
