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: 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.

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.

Background: We evaluated the effectiveness of gemcitabine and paclitaxel therapy in patients with metastatic urothelial carcinoma for whom two lines of sequential chemotherapy had been unsuccessful.
Methods: A total number of 105 patients who had previously received first-line chemotherapy consisting of gemcitabine and cisplatin or carboplatin, were treated with second-line gemcitabine and docetaxel therapy between June 2006 and May 2015. Of these patients, 15 with an Eastern Cooperative Oncology Group Performance Status of 0 or 1 were administered gemcitabine and paclitaxel as third-line treatment from 2013 after failure of the second-line therapy. For each 21-day cycle, gemcitabine (1000 mg/m2) was administered on days 1, 8, and 15, and paclitaxel (200 mg/m2) on day 1. Patients were assessed for each cycle and any adverse events were noted. Furthermore, a Short Form Health Survey questionnaire was used to assess each patient’s quality of life.
Results: Third-line gemcitabine and paclitaxel treatment cycles were undertaken for a median of four times (range 2–9). The disease control rate was 80.0%. After second-line gemcitabine and docetaxel therapy was completed, median progression-free survival and median overall survival were determined as 9.8 and 13.0 months, respectively. The only prognostic factor for overall survival, as determined by univariate and multivariate analyses, was third-line gemcitabine and paclitaxel therapy. Neutropenia (66.7%) and thrombocytopenia (53.3%) were noted as the grade 3 treatment-related toxicities. After two cycles of third-line gemcitabine and paclitaxel therapy, the pre- and post-treatment quality of life scores did not differ significantly.
Conclusions: Results demonstrate that third-line combination therapy using gemcitabine and paclitaxel is a feasible option for metastatic urothelial carcinoma patients.

Objectives: Gauze remnants form gauzeomas after surgery, if infection has not occurred. We present a case of gauzeoma diagnosed after surgery.Patient: A 72-year-old man noticed a mass in his lower abdomen. He had undergone surgery for left inguinal hernia 21 years ago. A retroperitoneal mass was found on computed tomography (CT) and magnetic resonance imaging (MRI), and he was then referred to our hospital. A detailed abdominal ultrasonography, CT, and MRI revealed a cystic mass with a bulkhead-like structure near the bladder. These findings indicated the possibility of a malignant cyst; hence, an open surgery was performed to excise the mass. Macroscopically, the specimen was clearly bound, covered with a capsule, and filled with pus and had a gauze inside.Results: Based on the patient history and position of the mass, it was diagnosed as gauzeoma, which had strayed into the retroperitoneal cavity during the surgery for inguinal hernia.Conclusion: The imaging findings of gauzeoma are diverse; hence, it is often difficult to diagnose without surgery. However, gauzeoma can be lethal if the cystic mass is infected; thus, it is important to diagnose it correctly.

A 76-year-old Japanese man visited a nearby medical clinic complaining of abdominal distention. He had undergone extraperitoneal laparoscopic prostatectomy at our institution 5 months before the onset of abdominal distention. An imaging study revealed a large cystic lesion, and biochemical examination of a sample obtained via cyst puncture led to a diagnosis of lymphocele. As the lymphocele was resistant to puncture, drainage, and sclerotherapy with minomycin, laparoscopic fenestration was performed. Although the patient developed an adhesive ileus postoperatively, the cyst has not recurred. Fenestration surgery is a feasible option for lymphocele refractory to various conservative therapies.
