Case Presentation: We present a 69-year-old lady with a surgical history of radical cystectomy and ileal neobladder that was complicated by a left ureteric stricture and poucho-vaginal fistula for which she underwent a left ureteric stent and bilateral percutaneous nephrostomy (PCN) insertions after which she lost to follow-up.
