Objective: Tamsulosin is often administered at a dose of 0.2 mg in Japan, Korea, and elsewhere in Asia, while a dose of 0.4 mg is more common in the West. In order to determine the higher dose might also be appropriate in the North-East Asian setting, we studied whether the effect of increasing the dose to 0.4 mg in Japanese patients who had dysuria associated with benign prostatic hyperplasia.Patients and Methods: Twenty-two cases with a voiding volume ≥ 100 ml assessed by uroflowmetry out of 31 patients with benign prostatic hyperplasia and an IPSS (International Prostate Symptom Score) ≥ 8 whose symptoms were controlled with 0.2 mg of tamsulosin were entered into this study. We evaluated IPSS and QOL (quality of life) score, urinary flow parameters and residual urine volume before and 4 weeks after increasing the dose of tamsulosin.Results: Statistical analyses performed using the Wilcoxon test showed no significant alteration in IPSS total score or QOL score with the increased dose, but Qmax (maximum urinary flow rate) improved from 10.1 ± 5.5 ml/s to 12.1 ± 6.5 ml/s (p = 0.013), and residual urine volume improved from 37.6 ± 26.4 ml to 22.2 ± 24.3 ml (p = 0.012). Two of the 31 patients complained of new symptoms; 1 complained of breast pain and the other complained of dizziness.Conclusions: From the lack of side effects of more than moderate grade in the present study, increasing the dose of tamsulosin might be recommended before switching patients to other drugs.

Carcinosarcoma of the bladder is a rare malignancy characterized by an intimate admixture of malignant epithelial elements (carcinoma) and malignant soft tissue elements (sarcoma). Patients with carcinosarcoma usually present with high-stage malignancy. Cystectomy or transurethral resection of the bladder tumor (TUR-Bt) is the preferred treatment, often followed by radiation therapy, but the prognosis is very poor1-7). To our knowledge, almost 80 cases have been reported in Japan, usually as case reports or small series6, 7). In almost all cases, the chief complaint was gross hematuria. We herein report a case of carcinosarcoma of the urinary bladder in a patient whose chief complaint was abdominal pain. His pain worsened, and the occurrence of hydronephrosis indicated that extremely rapid tumor growth may have occurred. No evidence of recurrence was noted 30 months after the performance of cystectomy.

Hemolytic uremic syndrome (HUS) is a heterogeneous disorder characterized by hemolytic anemia, thrombocytopenia and renal failure that occurs predominantly in infants and young children. However, HUS in adults has also been described as a complication of various chemotherapy regimens with a relatively poor prognosis. Since cisplatin is now widely used for treatment of solid cancers, it is necessary to take into account the possibility of cisplatin-induced hemolytic uremic syndrome as a rare but potentially fatal side- effect. Herein, we describe our experience with a 67-year old woman being treated for a urothelial carcinoma of the bladder who suffered chemotherapy-induced HUS after a cisplatin-based regimen. Plasmapheresis was carried out five times; however, her serum platelets remained depressed, and she subsequently died. We conclude that there is a high risk potential for HUS in patients undergoing intensive chemotherapy for advanced-stage bladder cancer.

Objective: Recently, holmium laser enucleation of the prostate (HoLEP) has been established as one method of endoscopic surgery for the treatment of benign prostate hyperplasia (BPH). The purpose of our study was to assess initial clinical experiences with HoLEP at our hospital.;Patients and Methods: A retrospective analysis was conducted of 28 patients with obstructive symptoms due to BPH who underwent HoLEP during the 13 months between February 2004 and March 2005.;Results: The mean age of the patients was 67.4 years (range 59 to 78 years). The mean enucleation tissue weight was 24.3 g (range 2 to 95 g), and the average operation time was 94.1 minutes (range 40 to 268 minutes). The mean duration of postoperative catheterization was 3.4 days (range 1 to 6 days). The mean urine flow rate improved, and each patient's satisfaction for voiding, measured on a 5-point scale, was good. There were no major complications during the operations except one case, which was completed with TUR-P because of uncontrollable bleeding. No patients required transfusions. Long-term complications included five cases of stress incontinence (19%), four of urethral stricture (14%), and three temporary retention, two of which required re-catheterization (10%).;Conclusion: HoLEP can be performed without major intraoperative complications. It is an effective treatment for obstructive symptoms due to BPH. However, there are many postoperative problems that must be resolved, including stress incontinence and urethral stricture because of our lack of experience, with HoLEP.

(Objective) Neoadjuvant hormonal therapy (NHT) before radical prostatectomy promotes the downstaging of primary lesions. A retrospective analysis was conducted of the relationship between NHT durations and positive surgical margin rates, as well as between positive surgical margin rates and three types of prostatectomy (antegrade radical prostatectomy, retrograde radical prostatectomy, and laparoscopic radical prostatectomy (LRP)).;(Materials and Methods) This study was a retrospective analysis of 257 patients treated with radical prostatectomy during the three years between April 2002 and March 2005. Of the 257 patients, 190 were treated by NHT. NHT durations were classified into “not conducted,” “<1 month,” “1-3 month,” “3-6 month” and “>6 month,” and the relationship between positive surgical margin rates and NHT durations was investigated. Seventy-four patients underwent antegrade radical prostatectomy, 131 were treated with retrograde radical prostatectomy, and 52 underwent LRP. Positive surgical margin rates were investigated according to the types of prostatectomy, as well as according to prostate-specific antigen (PSA) levels upon diagnosis.;(Results) Positive surgical margin rates were 53.8% in the “not conducted” and “<1 month” groups, 38.8% in the “1-3 month” group, 32.4% in the “3-6 month” group, and 10.7% in the >6 month” group. Positive surgical margin rates after open surgery (antegrade and retrograde) tended to decrease when NHT durations were longer, while those after LRP tended to increase inversely. No correlation was observed between PSA levels upon diagnosis and positive surgical margin rates or between presurgical PSA levels and NHT durations.;(Conclusion) Positive surgical margin rates were not significantly different when patients were treated with NHT for 1-3 months, but they tended to decrease when NHT was for >6 months. However, positive surgical margin rates after LRP increased when NHT continued for longer periods of time. This may the result of fibrous adhesion in the vicinity of the prostate due to long-term NHT which made the surgical margins unclear.

Objective: We carried out this study to clarify whether operative methods of laparoscopic prostatectomy (LRP) could become a standard therapy. The purpose was to evaluate the technical feasibility, oncologic effectiveness and perioperative and postoperative morbidity of LRP performed by a general urologist. Patients and Methods: Between June 2004 and May 2006, 30 patients with clinically localized prostate cancer consecutively underwent LRP by a single surgeon. Oncologic data were assessed by histopathological examination and by postoperative prostate-specific antigen (PSA) levels. Results: Complete laparoscopic removal of the prostate and seminal vesicles was achieved in all 30 patients. The average operation time was 250.9 min (range, 168 to 394 min). The total positive surgical margin rate was 20.7% (6 of 29 cases), with a total PSA recurrence rate was 23.3% (7 of 30 cases), but the frequencies tended to be decreased in the later phase cases. Perioperative complications were encountered in 5 patients; four of these patients were in the initial 10 cases. Two of the 30 cases (6.7%) required a blood transfusion (first case and 11th case). There were three surgical complications, one ureter injury, one rectal injury and one sigmoid serosal injury. The catheter duration intervals were reduced in the later cases. Conclusions: From our experience with one surgeon, with whom perioperative complications were concentrated in the initial 10 cases, we conclude that LRP should be performed by experienced surgeons after intensive training.

Hand hygiene is the foundation of effective infection control in health care settings, including in areas designated for blood collection. However, in such areas, patients are assigned in rapid succession and hand hygiene can lapse due to time pressure. Therefore, we examined a more efficient hand hygiene technique with consideration of these time constraints. An infection control issue was noted during a blood test procedure, based on Kiken Yochi Training. Meetings were then held to discuss the issue and a study was proposed to test a more efficient hand hygiene technique as a solution. The hand hygiene technique involved (1) performing hand hygiene after glove removal, (2) wearing gloves just before directly touching the patient, and (3) concentrating on the finger and hand areas involved in glove removal when performing hand hygiene using a rapid-drying hand disinfectant. These three items were compared before and after the change of procedure using a rapid-drying hand disinfectant. The results confirmed that it is possible to practice efficient hand hygiene by recognizing the areas of the hand that are contaminated during the blood collection procedure. Difficulties involving hand hygiene in a blood collection area include thoroughness in using one glove for one patient and time constraints. We suggest that performing effective infection control is possible by unifying the timing of appropriate hand hygiene with the timing of blood collection.

A 20-year-old man was admitted to our hospital with persistent cough and dyspnea. He had bilateral distention of the jugular veins, and swollen lymph nodes were palpable in the right subclavicular region. Plain X-ray and computed tomography (CT) of the chest showed a solid soft tissue mass in the upper mediastinum, with leftward displacement of the trachea and complete obstruction of the superior vena cava. Mediastinal radiotherapy (1.8 Gy/day) and methylprednisolone (100 mg/day) were started immediately. Biopsy of the right subclavicular lymph nodes revealed metastatic seminoma. The patient was referred for chemotherapy, which was performed with a combination of cisplatin, bleomycin and etoposide (BEP). A partial response was observed after completion of 3 cycles of chemotherapy, but there was no further tumor shrinkage after additional salvage chemotherapy. The patient is being followed up on an outpatient basis and has been free of recurrence for 32 months after intensive treatment.

Objective: There are few reports of the long-term outcomes of elderlypatients with prostate cancer. We analyzed data from our institution from the past 12years, including the patient history, treatment methods, and prognosis of patients withprostate cancer aged 80 years or more.
Patients and Methods: A total of 179 cases of prostate cancer in patientsaged 80 years or more were retrospectively evaluated. We divided them chronologically intogroups A, B, C, and D: Group A included 40 cases from 2002–2004; Group B, 48 cases from2005–2007; Group C, 46 cases from 2008–2010; and Group D, 45 cases from 2011–2013.
Results: Sixty-one (30%) patients changed treatment course. Interestingly,no cancer deaths occurred in the patients who changed treatment course. Although 14 (7.8%)cancer deaths occurred (A: B: C: D = 4: 4: 6: 0, respectively), all occurred in 2011 orlater.
Conclusion: In our study, over 50 patients who underwent treatment survivedfor 5 years or more. By treating prostate cancer in elderly patients when appropriate, wecan lower the mortality rate due to prostate cancer. Our results support the activetreatment of prostate cancer in elderly patients.
