Introduction:
Ureteral stent placement in robot-assisted intracorporeal ileal conduit formation (RICIC) is more challenging than extracorporeal urinary diversion. We developed a novel dedicated device called the Assistent guide for safe and smooth performance of ureteral stent placement by the patient-side surgeon (PSS).
Methods:
This study reviewed the clinical records of 59 patients underwent RICIC with a total of 110 ureteral stent placements: 59 stents were placed using the Assistent guide, and 51 stents were placed using a suction tip.
Results:
The stenting time was significantly shorter in the Assistent guide group than in the suction tip group. Even for beginners, the stenting time was significantly shorter. The PSSs' satisfaction score was significantly higher in the Assistent guide group. No complications associated with ureteral stent placement occurred.
Conclusions:
We showed the safety and efficacy of the Assistent guide for ureteral stent placement in RICIC.
