Sentinel lymph node dissection during radical cystectomy for bladder adenocarcinoma following gastrocystoplasty.

Patients with spina bifida are at increased risk of developing malignancy in the native or augmented bladder and tend to present with more advanced disease. Surgical guidelines for oncologic resections in patients with augmented bladders are not well described. Furthermore, there is limited knowledge regarding the changes in lymphatic drainage after bladder reconstruction. Herein we describe the case of a 45-year-old male with spina bifida who underwent gastrocystoplasty and developed adenocarcinoma of the augmented bladder segment 33 years later. We describe his surgical management with radical cystectomy and the use of sentinel lymph node dissection.
