Pyeloureteric magnetic anastomosis device to simplify laparoscopic pyeloplasty: a proof-of-concept study.

Laparoscopic pyeloplasty (LP) is a standard, but demanding operation. According to the European Association of Urology guidelines this procedure scores 13 out of 18 on the difficulty scale [1]. Articulating instruments, 3D video systems and robots may facilitate complex suturing of the ureteropelvic anastomosis at higher costs [2,3]. Magnetic compression anastomosis (magnamosis) has been used safely and effectively in the gastrointestinal tract [4,5], however not been applied in the urinary tract.
