A 67-year-old patient underwent robotic-assisted laparoscopic radical prostatectomy and experienced right ureteral lesion. The laceration was recognized intraoperatively and immediately repaired over the ureteral double J stent. The wire and the stent were first advanced distally to the bladder. Then the wire was pulled with its soft end, cranially through one of the side holes of the proximal end of the stent toward the kidney allowing exact positioning of the stent. Postoperative hospitalization was similar to a classic laparoscopic robotic-assisted prostatectomy. Robotic approach and the "side hole" technique represent an accurate and safe option in case of ureteral laceration management.

A critical factor in thrombus formation during venoarterial extracorporeal membrane oxygenation (VA ECMO) is prothrombotic flow dynamics generated by the drainage cannula's design. This study aimed to create and evaluate a novel drainage cannula design which optimized blood flow dynamics to reduce thrombus formation. Computational fluid dynamics (CFD) was used to iteratively vary drainage cannula design parameters such as inner wall shape and side hole shape.

Carinoplasty can be divided into the one-stoma method, the montage method, the double-barrel method, and the Miyamoto method. The one-stoma method is usually performed with right upper sleeve lobectomy, and with an anastomosis of the intermediate trunk to a carina. On the other hand, in the montage method, the double-barrel method or the Miyamoto method, carina is completely resected and the trachea, left main bronchus and right bronchus are divided into three pieces.

Introduction: The interaction between primary left ventricular output and Veno-arterial extracorporeal membrane pulmonary oxygenation (VA ECMO) flow may impede the perfusion of aortic vessels with hyperoxic blood, leading to differential oxygenation. ECMO return cannula design significantly influences the perfusion level of blood supplied via ECMO. This study aimed to investigate the impact of various cannula designs (side hole number) on intravascular flow patterns under different blood perfusion conditions.
