Is One Early Renographic Follow-Up Adequate to Measure the Success of Robotic Pyeloplasty?

Purpose: Diuretic renography (DRG) is commonly used to diagnose ureteropelvic junction obstruction (UPJO) and to evaluate the success of surgical repair (pyeloplasty). Duration, frequency, and interpretation of renographic follow-ups are still under dispute.

Methods: We retrospectively reviewed 94 consecutive patients diagnosed with UPJO who underwent a minimally invasive, robotically assisted laparoscopic pyeloplasty at our institution between January 2009 and September 2015.

Comparison of collagen-based vascular closure devices in patients with vs. without severe peripheral artery disease.

Purpose: To compare complication rates of a collagen-based vascular closure device (VCD) in patients with vs. without significant peripheral artery disease (PAD).

Methods: A total of 382 patients (268 men; mean age 64.

Utilization of collagen-based vascular closure devices in patients with severe peripheral artery disease.

Background: Collagen-based vascular closure devices (VCD) are commonly used after catheterization with femoral access. However, data about complication rates due to the utilization of VCDs in patients with known peripheral artery disease (PAD) of the lower limbs are inconsistent and patients with significant PAD are excluded in most VCD trials. In this study, we aimed to assess complication rates of collagen-based VCDs in patients with significant PAD.
