［Purpose］We examined the treatment results of patients who developed bladder cancer during maintenance hemodialysis at our hospital. ［Materials and Methods］This study included 5 males and 1 female who were treated for bladder cancer between January 2010 and December 2019. The primary reason for dialysis, dialysis period, clinical pathological results, surgical procedure, and prognosis were retrospectively examined. ［Results］The primary reason for dialysis was diabetic nephropathy in 4 cases and unknown in 2 cases. The median age at transurethral resection of the bladder tumor (TURBT) was 68 years, and the median dialysis period was 53 months. The initial symptom was hematuria in 5 cases and irregular genital bleeding in 1 case. Preoperative urinary cytology resulted in 5 cases and 1 case being classified as class 4 and class 5, respectively. TURBT was performed in all cases, and the pathological diagnosis was urothelial carcinoma in 5 cases and small cell neuroendocrine cancer in 1 case. All patients had high‒grade pT1 or more advanced disease, and 3 patients underwent total cystectomy. Intravesical recurrence was observed after TURBT in 2 cases, and metastasis developed after total cystectomy in 1 case, which resulted in death. ［Conclusion］It is important that dialysis patients undergo urinary tests/cytology regularly because bladder cancer that is detected during maintenance hemodialysis has high malignant potential, and many cases involve advanced disease.
