C. A. Bravi et al. [8]	Outcomes of Robot-Assisted Radical Prostatectomy with the Hugo RAS Surgical System: Initial Experience at a High-Volume Robotic Center	2023	Urology	112 patients Case Series	RARP ± ePNLD	Not reported	180 min	The odds of UC recovery was 36% (95% confidence interval [CI], 28–47%) at 1 month and 81% (95% CI, 72–89%) at 3 months. The median time to UC recovery was 36 days (95% CI, 34–44).
N. Ragavan et al. [7]	Robot-Assisted Laparoscopic Radical Prostatectomy Utilizing Hugo RAS Platform: Initial Experience	2023	Urology	34 patients Comparison with DaVinci	RARP	19 min	210 min	A radical resection and vesicourethral anastomosis were achieved in all cases. No major intra- or postoperative complications in up to 1-month follow-up were detected.
A. Totaro et al. [2]	The New Surgical Robotic Platform HUGOTM RAS: System Description and Docking Settings for Robot-Assisted Radical Prostatectomy	2022	Urology	7 patients Case Series	RARP	Not reported	Not reported	Operative times appeared to be easy reproducible and comparable to those obtained with the DaVinci system. No major system faults and conflicts between robotic arms were observed after the first procedure.
Sarchi L. et al. [6]	Robot-Assisted Radical Prostatectomy Feasibility and Setting with the HugoTM Robot-Assisted Surgery System	2022	Urology	3 cadavers Preclinical study	RARP	5 min	90 min	Docking and operative time were comparable to their clinical experience with other robotic systems. No intraoperative complications were recorded, no need for conversion or additional ports placement. No clashing occurred.
C. Bravi et al. [5]	Feasibility and Optimal Setting of Robot-Assisted Partial Nephrectomy with the Novel “Hugo” Robotic System: A Pre-Clinical Study	2022	Urology	3 cadavers Preclinical study	RAPN	7 min	105 min	Complications, described as damage of abdominal organs, did not occur. No robotic arm clashing was observed.
A. Gallioli et al. [4]	Initial experience of robot-assisted partial nephrectomy with HugoTM RAS system: implications for surgical setting	2023	Urology	10 patients Case Series	RAPN	9.5 min	138 min	One case of conversion to laparoscopic partial nephrectomy was reported, where the combination of a suboptimal trocars’ placement and hepatomegaly caused continuous clashing between robotic arms.
M. Raffaelli et al. [18]	The new robotic platform HugoTM RAS for lateral transabdominal adrenalectomy: a first world report of a series of five cases	2023	Urology	5 patients Case Series	Lateral trans-abdominal total adrenalectomy	8, 6, 5, 5 and 5 min	99, 139, 85, 153, and 119 min	No intraoperative complications occurred, but a total of 5 arm collision instances were observed (three for patient n.1, one for patient n.2 and one for patient n.4). A single postoperative complication happened.
V. Elorrieta et al. [3]	Robot assisted laparoscopic surgeries for nononcological urologic disease: initial experience with Hugo RAS system	2023	Urology	4 patients Retrospective Observational Study	Robot-assisted pyeloplasty, ureterolithotomy, ureteral reimplant, and nephrectomy	11 min 9 min 5.7 min 8.1 min	201 min 150 min 257 min 222 min	Comparable results to the previous robotic systems, suggesting the multiple potential uses of the Hugo RAS.
P. Bianchi et al. [15]	First worldwide report on Hugo RASTM surgical platform in right and left colectomy	2023	General Surgery	3 patients Case Series	Robot-assisted colectomy	8 min (median)	336, 340, 365 min	No system failure was recorded, although few adjustments had to be made on 1 right colectomy because of arm conflict; the modifications did not interfere with the total operative time.
Y. Quijano et al. [17]	Robot-assisted Nissen fundoplication with the new HUGOTM Robotic assisted system: first worldwide report with system description, docking settings and video	2023	General Surgery	1 patient Case Report	Robot-assisted Nissen fundoplication	3 min	100 min	Showed safety and feasibility of Nissen fundoplication for hiatal hernia with the Hugo™ RAS system and provided relevant data that may assist early adopters of this surgical platform.

[16]	Initial experience in a novel robotic system: HugoTM robotic assistant surgery system for robotic inguinal hernia repair	2022	General Surgery	1 patient Case Report	Robot-assisted inguinal hernia repair	Not reported	Not reported	Clinical operative and postoperative course was uncomplicated. Patient was discharged the following day. No recurrence was reported on a 3-month follow-up.
G. Monterossi [13]	The first European gynecological procedure with the new surgical robot Hugo RAS. A total hysterectomy and salpingo-oophorectomy in a woman affected by BRCA-1 mutation	2022	Gynecology	1 patient Case Report	Robot-assisted total hysterectomy and salpingo-oophorectomy	6 min	58 min	Gynecological surgery with Hugo™ RAS seems feasible, safe and effective as shown by initial experiences in urological surgery.
