title: Deceptive muscle invasive bladder cancer recurrence with benign biopsy foci after bladder sparing treatment.
abstract: Most of recurrent bladder carcinoma after partial cystectomy did not cause diagnostic difficulties for urologists, because of the appearance of typical papillary in ultrasonography or cystoscopy, and could be easily confirmed by tumor biopsy. Three patients, ages from 35 to 62 years, had undergone bladder sparing treatment for muscle invasive bladder cancer, all of them had biopsy revealed benign bladder lesion at surveillance cystoscopy. However, transurethral resection of bladder tumor showed high-grade muscle invasive urothelial bladder carcinoma for these patients. Two patients were thus delayed for timely cystectomy and consequently resulted in local or distal metastasis.As a result, we recommended that timely pelvic enhanced computed tomography and transurethral resection of bladder tumor were necessary when bladder lesion occurred after partial cystectomy, avoiding the possibility of missing muscle invasive urothelial bladder carcinoma recurrence and delaying timely cystectomy.
