Artificial urinary sphincters (AUS) are effective tools for the treatment of female stress urinary incontinence. Nonetheless, hydraulic sphincters present with some limitations: complex and time-consuming preparation, need for preserved manual dexterity and constant pressure exertion on the bladder neck. The ARTUS Artificial Urinary Sphincter is a novel electro-mechanical device designed to overcome these limitations thanks to its rapid and straight-forward implantation, intuitive remotely controlled manipulation and continuously adjustable cuff pressure.

The ARTUS system is currently under pre-market investigation in men, in an interventional, prospective, single arm, multicentric, international study. A cadaver lab session was carried out in Decembre 2024 to test the technical feasibility of ARTUS implantation in female patients. The procedure was performed by an expert surgeon with extensive experience in AUS implantation and robotic surgery.

One female patient was successfully implanted during the session. The technique has been developed following the principles of the traditional robot-assisted AUS implantation: the patient is placed in gynecological 23° Trendelenburg position. The robot has a 4-arms configuration. The procedure starts with the dissection of the vesicovaginal plane, to approach the bladder neck posteriorly. The lateral surfaces of the bladder neck are developed on both sides. The anterior peritoneum is opened to gain access to the antero-lateral surfaces of the bladder. The separation of the bladder neck from the vagina is performed through dissection of the pre-vaginal fascia bilaterally. The cuff is introduced and it is passed through the antero-lateral peri-vesical spaces, sliding behind the bladder neck from the right side to the left side. The anterior peritoneum is opened to gain access to the anterior surface of the bladder neck. The cuff is closed anteriorly, passing the transmission line inside the hole at the distal part of the cuff. The tightening around the bladder neck is achieved by pulling the transmission cable through. An optimal adjustment of the cuff around the bladder neck is provided tightening the ARTUS cuff clamping notch. Then, a supra-pubic 4 cm skin incision is made to implant the control unit. The tip of the cuff is passed outside through the incision. A lodge is prepared incising along the external oblique muscle aponeurosis. The cuff is connected to the control unit and a test with the remote control is performed to verify the functioning of the system. Finally, the control unit is placed into the lodge, anchored with non-absorbable sutures to the aponeurosis.

Robot-assisted ARTUS implantation is technically feasible in female patients. This straight-forward technique may reduce operative time. The device has the potential to reduce the pressure and facilitate manipulation in patients with impaired dexterity.
