To analyze the causes of misdiagnosis on multiple organ urothelial carcinoma and explore measures for prevention.

Three cases of misdiagnosis of multiple organ urothelial cancer from February 2006 to October 2012 were retrospectively analyzed.

Case 1 and case 2 were diagnosed as bladder transitional cell carcinoma for the first time, and had turbt in other hospital several times.Case 1 underwent laparoscopic radical cystectomy nephrectomy, nephrectomy and Bricker operations in other hospitals three months ago.Case 2 undergone renal ureter resection outside the hospital before admission.Case 3 underwent partial excision of kidney and ureter as renal pelvic cancer outside the hospital.After admission, all patients do urine cytology and B ultrasound, IVP, CTU or MRI examinations and cystoscope examination.Case 1 wasdiagnosed as recurrent bladder cancer after operation, right ureteral stump cancer after nephrectomy, left kidney seeper, kidney function incomplete, systemic multiple metastases.Case 2 was diagnosed as recurrent after transurethral resection of bladder tumor, right lower ureteral cancer, multiple organ metastasis, multiple organ failure.Cases 3 was diagnosed as carcinoma of renal pelvis and ureter right nephrectomy after partial resection, bladder cancer.Case 1 had double "J" tube drainage.Case 2 was given nutritional support and symptomatic treatment. Case 3 was given resection of bladder and ureter segments, and local chemotherapy for BCG bladder perfusion.All patients were followed up for six years.Case 1, case 2 died of tumor metastasis, multiple organ failure eight months and three months later respectiuely after surgery.Case 3 disease-free survived for six years and was still alive.

To improve the understanding of multiple organ urothelial cancer, it can not meet a single organ tumors diagnosis.Patients examined by CT, MRI, urine cytology, and all patients must do cystoscopy.Especially to the patients with recurrent bladder cancer, we should consider the possibility of upper tract cancer at the same time.Selecting the proper operation method is the key to the prolongation of survival.
