[Case report: simultaneous bilateral testicular tumors with different cell types].

A 29-year-old man was admitted to our hospital due to bilateral testicular tumors. The bilateral testicular tumors were palpated and visualized by ultrasound and magnetic resonance imaging (right 8 cm, left 6 cm in diameter). Bilateral high orchiectomies were performed after frozen storage of the sperm.

Long-term results of combined chemotherapy with gemcitabine and cisplatin for metastatic urothelial carcinomas.

Background: This retrospective study aimed to determine the long-term effects and toxicity of a combined chemotherapeutic regimen of gemcitabine and cisplatin (GC) in the treatment of metastatic urothelial carcinomas (UCs).

Methods: Seventy-one patients with metastatic UC were treated with GC (gemcitabine 1000 mg/m(2) on days 1, 8, and 15 and cisplatin 70 mg/m(2) on day 2 every 28 days). The patients were divided into 3 groups: patients who had not undergone prior chemotherapy (group 1), patients who relapsed more than 6 months after being treated with the prior cisplatin-based regimen (group 2), and patients in whom the prior cisplatin-based regimen demonstrated no effect (group 3).

[Intrascrotal rhabdomyosarcoma in adult: a case report].

The patient was a 34-year-old man presenting with the right intra-scrotal painless mass. With a diagnosis of right intrascrotal tumor, the patient underwent right high orchiectomy. The pathological diagnosis of pleomorphic rhabdomyosarcoma arisen from the right spermatic cord was made.

Peak flow rate is the best predictor of acute urinary retention following prostate brachytherapy: our experience and literature review.

Objectives: We prospectively investigated risk factors for acute urinary retention (AUR) following transperineal radioactive seed implantation for prostate cancer.

Methods: A total of 273 consecutive patients underwent transperineal ultrasound-guided prostate brachytherapy for clinical T1c-T3b prostate cancer. Preoperative factors included age; International Prostate Symptom score; planimetric prostate and transition volumes (TZV) measured by transrectal ultrasound; peak flow rate; post-void residual urine; neoadjuvant hormone therapy; use of pelvic radiation; and T stage.

Comparison of prostate and transition zone volume measured by the ellipsoid and planimetric methods with transrectal ultrasonography before seed implantation of prostate cancer.

A total of 122 men who were diagnosed with localized prostatic cancer underwent transrectal ultrasound and the volumes of their prostates and transitional zones were obtained using the planimetric method and the ellipsoid method. Mean age was 64.2 +/-13.

Gemcitabine and cisplatin for advanced urothelial carcinomas: the Ehime University Hospital experience.

Background: The aim of this study was to evaluate the efficacy and safety of a combined chemotherapy regimen, gemcitabine and cisplatin (GC), in the treatment of advanced urothelial carcinomas.

Methods: Fifty-five patients with advanced urothelial cancer were treated with GC (gemcitabine 1000 mg/m(2) on days 1, 8, and 15; cisplatin 70 mg/m(2) on day 2) every 28 days. The median follow-up was 30 months (range, 3 to 57 months).

[Gemcitabine and cisplatin therapy in advanced or metastatic urothelial cancer: comparison of side effect with MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin)].

Objective: Cisplatin-based combination chemotherapy has been considered as standard therapy for advanced or metastatic urothelial carcinoma. A recent study has, however, revealed that gemcitabine may have the potential to act synergistically with cisplatin. Therefore, the side effects of gemcitabine plus cisplatin (GC) therapy were compared with those of methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) therapy in patients with advanced or metastatic urothelial carcinoma.

Primary retroperitoneal lymphocele in a pregnant woman: the first report.

In a 32-year-old pregnant woman, routine ultrasonography revealed right hydronephrosis and a huge retroperitoneal mass (20 x 7 cm) containing a fluid collection. Percutaneous drainage of the mass was performed and 2 L of clear, yellowish fluid was collected. Four months following the delivery, a recurrent retroperitoneal lymphocele was identified.

Application of cardiopulmonary bypass for resection of renal cell carcinoma and adrenocortical carcinoma extending into the right atrium.

Aim: The application of cardiopulmonary bypass to atrial involvement represents an important advance that has improved the safety and technical efficacy of a difficult surgical undertaking. Our experiences of the management of extended thrombi into the right atrium in patients with retroperitoneal malignancy using a cardiopulmonary bypass were discussed.

Methods: Data were reviewed for five patients (two men and three women; mean age, 60.

[Cytomegalovirus infection in peptic ulcer in renal transplant recipient: a case report].

Gastroduodenal ulcers in renal transplant recipients are usually originated from excessive acid secretion or infection of Helicobacter pyroli. Herein, we report a case of cytomegalovirus (CMV)--induced gastric ulcer following cadaveric renal transplantation. The patient was a 48-year-old man with chronic renal failure and received cadaveric renal transplantation.

Effects of angiotensin II receptor blocker on proteinuria in renal transplant recipients.

Introduction: Therapeutic approaches directed at reducing proteinuria are under development. The aim of the present study was to prospectively elucidate the impact of losartan treatment in renal transplant recipients with persistent proteinuria.

Patients And Methods: Twenty-eight patients with persistent proteinuria or mild hypertension were assigned to receive losartan.

Cavernous hemangioma of the urinary bladder in an 8-year-old child.

An 8-year-old boy was admitted to Ehime University Hospital, Ehime, Japan, for the further investigation of a 5-month episode of gross hematuria accompanied by lower abdominal pain. Magnetic resonance imaging revealed a solid tumor measuring 3 cm in diameter of the bladder wall. Cystoscopy demonstrated a red, wide-based, nodular tumor situated on the dome of the bladder.
