Robot-Assisted Cystectomy With Intracorporeal Diversion for Bladder Intra-diverticular Tumor: A Special Case Report.

This report details the case of a 60-year-old male with a grade 3 intra-diverticular bladder tumor originating from an acquired bladder diverticula. The patient presented with painless gross hematuria lasting three weeks. Imaging and histopathological analysis confirmed a high-grade papillary transitional cell carcinoma. He underwent robot-assisted radical cystectomy with pelvic lymphadenectomy and the creation of an intracorporeal Studer neobladder. The surgery was successful, and the patient had an uneventful recovery. Intra-diverticular bladder tumors are rare and pose diagnostic and therapeutic challenges due to their unique anatomy and higher grade. Robot-assisted radical cystectomy has become the preferred approach at high-volume centers, providing reduced morbidity and excellent outcomes. For advanced cases, multimodal treatments such as neoadjuvant chemotherapy are crucial, emphasizing the need for individualized care. This case highlights the effectiveness of personalized, minimally invasive techniques and the importance of multidisciplinary collaboration in managing bladder tumors within diverticula.
