Bladder Disease

The goal of this clinical trial research study is to evaluate the impact of preoperative oral immunonutrition (IN) on post-operative complications in patients undergoing a cystectomy. As a secondary focus, this study will aim to develop a signature that would identify patients that would benefit the most from IN. This is a multicentric (Swiss: N=3), prospective, controlled, pragmatic, parallel-group comparative study with block randomization stratified by centers.

The goal of this clinical trial is to demonstrate the feasibility of bladder transplantation in patients with terminal bladder diseases who would benefit from a new bladder or a combined kidney and bladder transplant. The main questions it aims to answer are: * Is human bladder transplantation feasible and safe? * How will the new bladder function in terms of storage and emptying? Participants will undergo a bladder-only or combined kidney and bladder transplantation. They will then be followed for two years to evaluate the efficacy, safety, and functionality of the bladder transplant.

This study aims to evaluate a catheter-free method for delivering medications directly into the bladder, known as intravesical instillation, which is commonly used to treat conditions such as interstitial cystitis/bladder pain syndrome (IC/BPS), recurrent urinary tract infections, bladder cancer, and post-chemotherapy or post-radiation cystitis. The study investigates whether this method, which eliminates the need for catheterization, reduces discomfort and complications while maintaining treatment effectiveness. By collecting data on patient experiences and outcomes, the study seeks to determine if this approach provides a safer and more comfortable alternative to traditional catheter-based treatments.

A database has been created and will be used in which data will be collected in electronic format relating to adult patients who underwent one of the following endoscopic resection surgeries: TURBK, MAPPING, TURBK SECOND LOOK, BLADDER BIOPSIES.
