Successful Outcomes in Robot-Assisted Laparoscopic Pyeloplasty Using a Unidirectional Barbed Suture.

Introduction: Intracorporeal suturing is considered to be the most challenging aspect of laparoscopic and robotic surgery. To overcome this problem, barbed self-retaining sutures have been effectively employed in various minimally invasive endourologic surgeries. However, the use of this suture has been recently cautioned for pyeloplasty due to a high failure rate.
