Double kissing crush versus culotte for bifurcation percutaneous coronary interventions: insights from the PROGRESS-BIFURCATION registry.

Background: Upfront 2-stent techniques are often used in bifurcation percutaneous coronary interventions (PCI), but there is controversy about optimal strategy selection.

Methods: The authors examined the clinical and angiographic characteristics and long-term outcomes of 232 bifurcation PCIs that were performed using the double kissing (DK) crush or culotte technique in 216 patients between 2014 and 2023 using data from the Prospective Global Registry for the Study of Bifurcation Lesion Interventions (NCT05100992). The inverse probability of treatment weighted (IPTW) Cox proportional hazards model was used to assess long-term outcomes.

Primary Renal Neuroblastoma: A Case Report and Review of the Literature.

Introduction: Neuroblastoma is the most common extracranial solid tumor found in childhood.

Case Representation: Primary renal neuroblastoma has been reported in the literature as case reports. Almost all cases had a preliminary diagnosis of Wilms tumor and were diagnosed as neuroblastoma after nephrectomy.

Bifurcation Percutaneous Coronary Intervention in Patients Aged ≥80 Years: Insights from the Prospective Global Registry for the Study of Bifurcation Lesion Interventions Registry.

The outcomes of bifurcation percutaneous coronary intervention (PCI) in patients aged ≥80 and ≥90 years have received limited study. We compared the procedural characteristics and outcomes of bifurcation PCIs in patients aged ≥80 years and those aged <80 years in a multicenter registry. Of 1,253 patients who underwent 1,262 bifurcation PCIs between 2014 and 2024 at 6 centers, 194 (15%) were aged ≥80 and ≥90 years.

Comparison of tip-bendable aspiration-assisted and standard access sheaths in the treatment of lower calyceal stones.

Objective: The aim of this study was to compare the success and complication rates of retrograde intrarenal surgery for lower calyceal renal stones performed with novel tip-bendable suction ureteral access sheaths and standard ureteral access sheaths.

Methods: Between March 2023 and March 2024, a total of 88 patients underwent retrograde intrarenal surgery for lower renal calyceal stones smaller than 20 mm. Based on the access sheath used, patients were divided into two groups: Group 1 (n=43) included patients treated with novel tip-bendable suction ureteral access sheaths and Group 2 (n=45) included patients treated with standard ureteral access sheaths.
