Prospective evaluation of scrotal ultrasound and intratesticular perfusion by color-coded duplex sonography (CCDS) in TESE patients with azoospermia.

Purpose: The objective of this study was to assess whether CCDS might improve the outcome of testicular sperm retrieval in patients with azoospermia. Furthermore, we evaluated potential sonographic alterations of the testis before and after trifocal and Micro-TESE.

Methods: 78 patients were enrolled prospectively: 24 with obstructive azoospermia (OA) and 54 with non-obstructive azoospermia (NOA).

Detection of normal intratesticular perfusion using color coded duplex sonography obviates need for scrotal exploration in patients with suspected testicular torsion.

Purpose: Although color coded duplex sonography is useful for visualizing testicular perfusion in patients with clinical suspicion of testicular torsion, fear of overlooking the condition itself remains. Thus, routine scrotal exploration in every patient with acute scrotal pain is common at many centers. We assessed the efficacy of color coded duplex sonography in predicting the need for scrotal exploration in patients with clinical suspicion of testicular torsion.

Congenital phimosis in patients with and without lichen sclerosus: distinct expression patterns of tissue remodeling associated genes.

Purpose: Lichen sclerosus is a potentially important factor in the ongoing debate concerning the pathology of persistent congenital phimosis. We assessed the molecular differences of congenital phimosis in boys with and without lichen sclerosus compared to age matched boys with fully retractable foreskins to gain more insight into the pathogenesis of fibrotic remodeling of the prepuce.

Materials And Methods: A total of 150 boys were circumcised in a prospective study between 2007 and 2009.

Evaluation of penile perfusion by color-coded duplex sonography in the management of erectile dysfunction.

The etiology of erectile dysfunction is wide ranging. Penile vascular disorders may result in impaired erection or complete impotence. Almost 30% of erectile dysfunction is due to the presence of systemic disease which affects the blood supply to the penis.

Questionable efficacy of extracorporeal shock wave therapy for Peyronie's disease: results of a prospective approach.

Purpose: Extracorporeal shock wave therapy (ESWT) for Peyronie's disease is still a topic of debate. We evaluated the effects of ESWT in a large series of patients with Peyronie's disease via a prospective approach.

Materials And Methods: In a prospective study 114 patients with Peyronie's disease were treated with ESWT.

Seminoma in an intra-abdominal testis misdiagnosed as a kidney tumor and associated with ipsilateral renal agenesis.

We present a case of seminoma found in an intra-abdominal testis and associated with ipsilateral renal agenesis and absence of the ipsilateral seminal vesicle. Although malignant tumor degeneration in an undescended intra-abdominal testis is rare, understanding its radiologic appearance is important in order to confirm the diagnosis preoperatively and detect possible malformations of other organs.
