Urothelial carcinoma accounts for 90% of all the cases of bladder cancer. Although many cases can be easily managed by local excision, urothelial carcinoma rather frequently recurs, tends to progress to muscle invasion, and requires regular follow-ups. Urine cytology is a main approach for the follow-up of bladder tumors. It is noninvasive, but it has low sensitivity of around 50% with using the conventional cytospin preparation. Liquid-based cytology (LBC) has been developed as a replacement for the conventional technique. We compared the cytomorphometric parameters of ThinPrep(R) and cytospin preparation urine cytology to see whether there are definite differences between the two methods and which technique allows malignant cells to be more effectively discriminated from benign cells. The nuclear-to-cytoplasmic ratio value, as measured by digital image analysis, was efficient for differentiating malignant and benign urothelial cells, and this was irrespective of the preparation method and the tumor grade. Neither the ThinPrep(R) nor the conventional preparation cytology was definitely superior for distinguishing malignant cells from benign cells by cytomorphometric analysis of the adequately preserved cells. However, the ThinPrep(R) preparation showed significant advantages when considering the better preservation and cellularity with a clear background.

PURPOSE: To evaluate the direct anti-cancer effect of a single instillation of epirubicin (SIE) after transurethral resection of bladder tumor (TURBT) for non-muscle-invasive bladder cancer (NMIBC) by analysis of immediate urine cytology (IUC). MATERIALS AND METHODS: We reviewed the records of 158 patients who had IUC after TURBT for NMIBC. Fifty-six patients were treated with SIE after TURBT and 102 patients were not treated with SIE. The direct anti-cancer effect of SIE was compared in the two groups according to the result of IUC. The relationship between SIE and IUC in NMIBC was analyzed by use of multivariate Cox proportional hazards regression models. RESULTS: The IUC-positive rate was 33.9% in the SIE group and 42.1% in the non-SIE group (p=0.005). The IUC-positive rate was lower in the SIE group than in the non-SIE group for each factor, including tumor stage, tumor grade, tumor size, tumor multiplicity, and preoperative urine cytology. Multivariate Cox proportional hazards regression analysis revealed that SIE was significantly associated with a negative IUC result in patients with NMIBC (HR, 0.163) (p<0.001). CONCLUSIONS: These results indicate the direct anti-cancer effect of SIE in patients who undergo TURBT for NMIBC.

We encountered two bladder cancer patients who suffered from perineal pain that was intractable despite the use of adjuvant medication. A phenol intrathecal (saddle) block was performed without any specific complications. The results were excellent and allowed the systemic opiate dose to be reduced by more than 80%. We report our clinical experience, including a brief review of the relevant literature.
