Preoperative Physical Activity Improvement with the Use of Activity Trackers in Patients Undergoing Radical Cystectomy-A Bicentric, Open-label, Randomised Controlled Trial: A Clinical Study Protocol of the PreAct Trial.

This study protocol shows the structured design of the randomised controlled phase 3 "PreAct" trial. It hypothesises the use of a fitness tracker-based prehabilitation programme to increase the physical activity of patients prior to radical cystectomy, as measured by the average number of steps per day.

Comparison of distance versus in-person laparoscopy training using a low-cost laparoscopy simulator-a randomized controlled multi-center trial.

Introduction: Simulation training programs are essential for novice surgeons to acquire basic experience to master laparoscopic skills. However, current state-of-the-art laparoscopy simulators are still expensive, limiting the accessibility to practical training lessons. Furthermore, training is time intensive and requires extensive spatial capacity, limiting its availability to surgeons.

Tranexamic acid reduces perioperative blood transfusions following open radical cystectomy - a propensity-score matched analysis.

Purpose: Radical cystectomy is associated with bleeding and high transfusion rates, presenting challenges in patient management. This study investigated the prophylactic use of tranexamic acid during radical cystectomy.

Methods: All consecutive patients treated with radical cystectomy at a tertiary care university center were included from a prospectively maintained database.

Spectral characterization of intraoperative renal perfusion using hyperspectral imaging and artificial intelligence.

Accurate intraoperative assessment of organ perfusion is a pivotal determinant in preserving organ function e.g. during kidney surgery including partial nephrectomy or kidney transplantation.
