Intra-abdominal desmoid tumor mimicking local recurrence of renal cell carcinoma after laparoscopic partial nephrectomy.

A 64-year-old man had an intra-abdominal mass that was detected in a follow-up examination after laparoscopic partial nephrectomy for renal cell carcinoma (RCC). CT showed an enhanced mass of 2.5-cm diameter near the right kidney, where partial nephrectomy had been performed.

Male squirting: Analysis of one case using color Doppler ultrasonography.

Introduction: There is no scientific evidence for the mechanism of male squirting, although the term is common in mass media. Here, we describe the first recording of male squirting using color Doppler ultrasonography.

Case Presentation: We recruited a 25-year-old male volunteer who was able to have male squirting.

Practical application of color Doppler ultrasonography in patients with ejaculatory dysfunction.

We describe two cases in which dynamic analysis of ejaculation using color Doppler ultrasonography was useful in diagnosis of ejaculatory dysfunction and planning of therapy. The first patient was a 32-year-old man with a diagnosis of retrograde ejaculation. A bladder neck collagen injection was carried out, as the main cause was thought to be the bladder neck remaining open during ejaculation.

Long-term safety and efficacy of two different antimuscarinics, imidafenacin and solifenacin, for treatment of overactive bladder: a prospective randomized controlled study.

Objective: The aim of this study was to assess the efficacy and safety of long-term treatment with two different antimuscarinics, imidafenacin and solifenacin, in patients with overactive bladder (OAB).

Patients And Methods: Male or female patients 20 years of age or older who had urgency (more than 1 episode in 24 h) were randomized into two groups: group I, imidafenacin (0.1 mg twice daily), and group S, solifenacin (5 mg once daily) for a 12-month treatment regimen.

Comparison of Two Different α1-Adrenoceptor Antagonists, Tamsulosin and Silodosin, in the Treatment of Male Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Hyperplasia: A Prospective Randomized Crossover Study.

Objectives: We assessed the efficacy and safety of two α1-adrenoceptor antagonists, tamsulosin and silodosin, in the treatment of male lower urinary tract symptoms.

Methods: Men aged 50 years or older who had a total International Prostate Symptom Score (IPSS) of 8 or higher were enrolled in this study. Forty-six patients were randomized into two groups.

Retroperitoneoscopic nephrectomy for treatment of a case of left single ectopic ureter accompanied by dysplastic kidney.

We report the case of a 7-year-old girl with a single ectopic ureter who was treated with retroperitoneoscopic nephrectomy for a chief complaint of urinary incontinence. Preoperative CT showed a contrasted dysplastic kidney of 1cm in the renal fossa and a left ureteral opening into the vagina. Retroperitoneoscopic left nephrectomy was conducted with opening of the lateroconal fascia to enable identification of the dysplastic kidney.

Salvage high-dose-rate brachytherapy for local prostate cancer recurrence after radiotherapy - preliminary results.

Objective: To assess the preliminary clinical results of salvage high-dose-rate brachytherapy (HDR-BT) applied in cases of suspected local recurrence or of residual tumour after radiotherapy.

Patients And Methods: The subjects were 11 patients who met the above conditions and underwent salvage HDR-BT between December 2006 and January 2009. The T stage at the initial treatment was T1c in three patients, T2 in three patients and T3 in five patients.

A Retroperitoneal Dedifferentiated Liposarcoma Producing Granulocyte Colony-Stimulating Factor Accompanied by Spontaneous Rupture: PET/CT Imaging of a G-CSF-Producing Tumor.

The patient was a 63-year-old man who was referred to our hospital as an emergency case with the chief complaint of abdominal pain. An abdominal CT revealed a right retroperitoneal tumor of 15 cm and retroperitoneal bleeding. After a transcatheter arterial embolization was performed, the patient was transferred to our department.

Effects of three types of alpha-1 adrenoceptor blocker on lower urinary tract symptoms and sexual function in males with benign prostatic hyperplasia.

Objectives: The aim of the present study was to explore the effects of three different types of alpha-1 adrenoceptor blockers (α1-blocker) on lower urinary tract symptoms (LUTS), erectile dysfunction (ED) and ejaculatory dysfunction (EjD) in patients with benign prostatic hyperplasia.

Methods: A total of 136 male LUTS patients aged 50-80 years with International Prostate Symptom Score (IPSS) ≥8 were enrolled. They were divided into three groups.

Ejaculatory dysfunction caused by the new alpha1-blocker silodosin: A preliminary study to analyze human ejaculation using color Doppler ultrasonography.

Objectives: In order to clinically investigate the mechanism of ejaculatory dysfunction attributable to the alpha1-blocker silodosin, a real-time observation of ejaculation by healthy males was performed.

Methods: Following intake of silodosin, a newly developed selective alpha1-blocker for benign prostatic hypertrophy, ejaculation was dynamically observed using color Doppler ultrasound in three healthy males. Normal ejaculation was also investigated in the same manner.

Optimal approach for prostate cancer detection as initial biopsy: prospective randomized study comparing transperineal versus transrectal systematic 12-core biopsy.

Objectives: Transperineal and transrectal prostate biopsy are both used for prostate cancer detection. However, which approach is superior remains unknown. In this study, we performed a prospective randomized study to compare the efficacy of transperineal versus transrectal 12-core initial prostate biopsy.

A novel technique for approaching the endopelvic fascia in retropubic radical prostatectomy, based on an anatomical study of fixed and fresh cadavers.

Objective: To present the anatomical basis and details of a technique for an approach to the endopelvic fascia devised to preserve urinary continence.

Patients, Materials And Methods: For cross-sectional macroscopic observation, seven formalin-fixed specimens of the male pelvic contents including the pelvic wall were serially sectioned at a 5-mm thickness. Semi-serial sections from eight other specimens were examined histologically.
