Anterior urethral strictures affect the male urethra between the tip of the penis and the apex of the prostate. These form the bulk of urethral strictures in men. The common causes for urethral strictures seem to be idiopathic or related to instrumentation of the urethra. Clinically, patients have varying obstructive symptoms associated with the progressive narrowing of the urethral lumen. Trea...

Urethral stricture after radiation therapy for localized prostate cancer is a delicate problem as the decreased availability of tissue healing and the close relation to the sphincter complicates any surgical approach. We here review the pathophysiology, dosimetry, and the disease specific aspects of urethral strictures after radiotherapy. Moreover we discuss different treatment option such as d...

INTRODUCTION Urethral injury is an uncommon surgical complication of penile prosthesis (PP) surgery. Conventional dogma requires abortion of the procedure if the adjacent corporal body is involved or delayed implantation to avert device infection associated with urinary extravasation. Besides the setback of the aborted surgery, this management approach also presents the possible difficulty of e...

BACKGROUND The ability to achieve a long-term, stricture-free urethral repair is one of the ongoing challenges of reconstructive urologic surgery. A successful initial repair is critical, as repeat procedures are difficult, owing to distortion, scarring, and short urethral stumps. METHODS We describe a technique in which the gracilis muscle flap is laid on or wrapped around the urethral repai...

OBJECTIVES To describe my experience of vaginal mesh extrusion using the monofilament polypropylene transobturator sling, the Mentor ObTape. The Mentor ObTape was the first transobturator sling developed as an alternative to the retropubic commercially available suburethral slings for providing mid-urethral support as treatment of female stress urinary incontinence. METHODS Thirty patients un...

Inside Front Cover: Protracted inflammation following urethral reconstruction precedes multiple clinical complications. High aspect-ratio anti-inflammatory peptide amphiphiles can modulate the participation of pro-inflammatory macrophages (red) and anti-inflammatory, pro-regenerative (green) in order to recapitulate native tissue. This is reported by Yvonne Y. Chan, Matthew I. Bury, Natalie J. ...

Tubular type I collagen biomatrices with and without growth factors (GFs) were constructed and evaluated in a rabbit model for critical urethral defects. Porous tubular biomatrices with an inner diameter of 3  mm were prepared using highly purified collagen fibrils and were crosslinked with or without heparin. Heparinized biomatrices were supplemented with the heparin-binding GFs vascular endot...
