Silodosin versus naftopidil in the treatment of premature ejaculation: A prospective multicenter trial.

Objectives: To determine the efficacy of two α1-adrenoceptor antagonists with different affinities for α1-adrenoceptor subtypes, silodosin and naftopidil, in the treatment of premature ejaculation.

Methods: This was a prospective, open-label, multicenter trial. A total of 26 patients with untreated acquired premature ejaculation were enrolled.

[A case of primary testicular malignant lymphoma associated with contralateral testicular recurrence after a nine-year interval: a case report].

A 69-year-old man visited our hospital in February 1996 with a chief complain of left scrotal swelling. The left scrotal content was hard by palpation and ultrasonography showed a hypo-echoic lesion. Left high orchiectomy was performed with suspicion of a testicular tumor.

[Assessment of single-dose regimen for antimicrobial prophylaxis to prevent perioperative infection in urologic surgery].

A single-dose ofantimicrobial prophylaxis (AMP) was administered parenterally for prevention of perioperative infection in a total of 206 urologic surgeries including 114 endoscopic-instrumental, 92 clean, and 20 clean-contaminated procedures between January and December, 2007, and surgical site infections (SSI), urinary tract infections (UTI), and remote infections (RI) were prospectively surveyed. The definition of a single-dose of AMP allowed the administration of a second dose of an antimicrobial during a surgical procedure that exceeded 3 hours but not parenteral or oral administration at the end of the procedure, in the recovery room, or at a later time over a period of more than 24 hours. UTI was observed in 3 cases (2.

[A case report of juxtaglomerular cell tumor incidently found with a tumor hemorrhage].

A 17-year-old man was admitted to our hospital with a chief complaint of right flank pain. Both computed tomography and magnetic resonance imaging demonstrated a tumor hemorrhage in a mass located at the upper pole of the right kidney. He had a high blood pressure of 220/100 mmHg associated with high serum renin activity (36.

[Prostate cancer diagnosed through the biopsy of the bone metastatic lesion; a case report].

An 80-year-old man visited our clinic with the chief complaint of asymptomatic macroscopic hematuria secondary to anticoagulant medicine. Although digital rectal examination was normal, a high serum prostate specific antigen (PSA) level (85.9 ng/ml) led us to perform sextant prostate biopsy, resulting in negative for cancer.

[A case of CA19-9 producing transitional cell carcinoma of the ureter].

We report a case of CA19-9 producing urothelial carcinoma of the right ureter. A 61-year-old male patient who had an extremely high value of serum CA19-9 (1,185 U/ml) with right hydronephrosis was referred to us. Magnetic resonance urography and retrograde ureterography revealed a long irregular filling defect in the right distal ureter.
