On-clamp partial nephrectomy for the surgical treatment of renal masses poses the risk of ischemia and greater post-operative renal function loss. Conversely, the off-clamp technique might enhance renal function preservation by avoiding any ischemia time. Nevertheless, the debate persists regarding the efficacy of the on- versus off-clamp partial nephrectomy in achieving better surgical, functional, and oncological outcomes.

In February 2021 Medtronic (Minneapolis, MN) launched the HUGO™ Robot-Assisted Surgery (RAS) System in the global market. The aim of the current study is to describe the first case series and the optimal setup of robot-assisted pyeloplasty procedure, performed with HUGO RAS system in a tertiary referral robotic center. Data from consecutive patients who underwent robot-assisted pyeloplasty at Onze-Lieve-Vrouwziekenhuis Hospital (Aalst, Belgium) were recorded.

Objective: In the last years, robotic surgery was introduced in several different settings with good perioperative results. However, its role in the management of adrenal masses is still debated. In order to provide a contribution to this field, we described our step-by-step technique for robotic adrenalectomy (RA) and related modifications according to the type of adrenal mass treated.

Purpose: In the emerging field of robotics, only few studies investigated the transition between different robotic platforms in terms of surgical outcomes. We aimed at assessing surgical outcomes of patients receiving robot-assisted radical prostatectomy (RARP) and robot-assisted partial nephrectomy (RAPN) at a high-volume robotic center during the transition from Si to Xi Da Vinci surgical systems.

Methods: We analyzed data of 1884 patients undergoing RARP (n = 1437, 76%) and RAPN (n = 447, 24%) at OLV hospital (Aalst, Belgium) between 2011 and 2021.

There are only a few clinical data on nononcologic procedures performed with the new Hugo™ robot-assisted surgery (RAS) system. Robot-assisted simple prostatectomy (RASP) is a minimally invasive treatment option for benign prostatic hyperplasia, and it demonstrated equal early functional and better perioperative outcomes as compared with open simple prostatectomy. In this article, we reported the first large series of RASP performed with Hugo RAS system.

Objectives: An increasing number of urologists is switching from transrectal (TR) to transperineal (TP) biopsy procedures for the diagnosis of prostate cancer. Local anesthesia (LA) might be advantageous in terms of patient management, risks and costs. We aimed to evaluate the tolerability and complication rates of TP prostate biopsy performed under LA.

Robot-assisted simple prostatectomy (RASP) and holmium laser enucleation of the prostate (HoLEP) are both well-established, minimally invasive surgical treatment options for lower urinary tract symptoms caused by benign prostatic enlargement. We have reported the first comparative analysis of both techniques in patients with prostates of ≥200 cc. Between 2009 and 2020 a total of 53 patients with a prostate volume of ≥200 cc were surgically treated at OLV Hospital Aalst (Belgium): 31 underwent RASP and 22 underwent HoLEP.

Introduction: Bladder neck dissection is one of the most delicate surgical steps of robotic-assisted radical prostatectomy (RARP) [1, 2], and it may affect surgical margins rate and functional outcomes [3, 4]. Given the relationship between outcomes and surgical experience [5-7], it is crucial to implement a step-by-step approach for each surgical step of the procedure, especially in the most challenging part of the intervention. In this video compilation, we described the techniques for bladder neck dissection utilized at OLV Hospital (Aalst, Belgium).

Background: The evidence of prognostic factors and individualized surveillance strategies for upper tract urothelial carcinoma are still weak.

Objectives: To evaluate whether the history of previous malignancy (HPM) affects the oncological outcomes of upper tract urothelial carcinoma (UTUC).

Methods: The CROES-UTUC registry is an international, observational, multicenter cohort study on patients diagnosed with UTUC.

Article Synopsis
  • Several barriers hinder the use of augmented reality (AR) in robotic renal surgery, such as visibility issues with instruments and alignment problems of 3D models.
  • A deep learning algorithm was developed to detect surgical instruments in real-time during procedures like partial nephrectomy and kidney transplantation, using data from over 65,000 labeled instruments.
  • The setup, tested across three hospitals and by four surgeons, improves AR surgery safety but requires further optimization for faster video processing and better handling of organ deformation in clinical settings.

Background: Current literature does not provide large-scale data regarding clinical outcomes of robot-assisted (RAPN) versus open (OPN) partial nephrectomy. Moreover, data assessing predictors of long-term oncologic outcomes after RAPN are scarce.

Objective: To compare perioperative, functional, and oncologic outcomes of RAPN versus OPN, and to investigate the predictors of oncologic outcomes after RAPN.

Clinical data on robot-assisted radical prostatectomy (RARP) performed with the new Hugo robot-assisted surgery (RAS) system are scarce. We described surgical outcomes of 112 consecutive patients who underwent RARP ± extended pelvic lymph-node dissection (ePLND) at OLV Hospital (Aalst, Belgium) between February and November 2022. The median age was 65 yr (interquartile range [IQR] 60-70) and median preoperative prostate-specific antigen (PSA) was 7.

Renal cell carcinoma is among major causes of death in patients with Von Hippel-Lindau (VHL) syndrome, and it usually presents with multiple and bilateral lesions that may require multiple renal surgeries. This, in turn, may compromise renal function, resulting in end-stage renal disease. To minimize renal function impairment in these patients, great importance is given to the preservation of functional parenchyma with the use of nephron-sparing techniques.

  • - The study aimed to validate the Yonsei nomogram, which predicts the risk of developing new-onset chronic kidney disease (CKD) in patients undergoing partial nephrectomy for renal masses, using data from 3526 patients across 23 centers from 2000 to 2018.
  • - Findings indicated that 19.4% of patients developed new-onset CKD, with a 5-year CKD-free progression rate of 77.9%; the nomogram showed increasing accuracy in predicting CKD stages over time with AUC values ranging from 0.69 to 0.78.
  • - The results highlighted strong calibration of the nomogram, making it a useful tool for estimating individual CKD risk during long
