OBJECTIVE The incidence of urethral injuries in children is rare due to the fact that the urethra is short, mobile and protected by the pubic bone. The management of urethral trauma in childhood remains controversial because of the limited expertise of most urologists. MATERIAL AND METHODS We performed a literature review by searching the Medline database for articles published between 1975 a...

BACKGROUND In the case of buccal mucosa graft (BMG) urethroplasty for penile urethral strictures (PUS), it is supposed that the ventral onlay (VO) would not assure sufficient nutritional and mechanical support. Because VO requires only one ventral incision of the stenotic urethral segment and does not affect the urethral vasculature, we have design a prospective study related to this issue. M...

OBJECTIVE To compare outcomes for single urethral cuff downsizing versus tandem cuff placement during artificial urinary sphincter (AUS) revision for urethral atrophy. MATERIALS AND METHODS We identified 1778 AUS surgeries performed at our institution from 1990-2014. Of these, 406 were first AUS revisions, including 69 revisions for urethral atrophy. Multiple clinical and surgical variables w...

OBJECTIVES To study the feasibility of urethral reconstruction with two urethroplasty techniques using an elastin and collagen heterograft in rabbits. MATERIALS AND METHODS Fifty-two male rabbits were studied. Two types of injury, (1) a 1.5 x 0.6 cm2 semicircumferential defect; (2) a 1.5 cm segmental defect of the penile urethra, were created and repaired using size-matched elastin and collag...

Introduction. Concealed-buried penis is an acquired condition associated with obesity, challenging to both manage and repair. Urethral stricture is a more common disorder with multiple etiologies. Lichen sclerosus is a significant known cause of urethral stricture, implicated in up to 30%. We hypothesize that patients with buried penis have a higher rate of urethral stricture and lichen scleros...

BACKGROUND AND PURPOSE Histotripsy is a nonthermal focused ultrasound technology that uses acoustic cavitation to homogenize tissue. Previous research has demonstrated that the prostatic urethra is more resistant to histotripsy effects than prostate parenchyma, a finding that may complicate the creation of transurethral resection of the prostate-like treatment cavities. The purpose of this stud...

Background. Adult patients with urethral stricture after childhood hypospadias surgeries are infrequently discussed in the literature. We report our experience in treating such patients. Materials and Methods. A retrospective chart review was performed. From 2002 through 2007, nine consecutive adult patients who had current urethral stricture and had undergone childhood hypospadias surgeries we...

AIMS Urethral pathophysiology is often neglected in discussions of bladder dysfunction. It has been debated whether "urethral sphincter instability," referred to based on observed "urethral pressure variations," is an important aspect of overactive bladder syndrome (OAB). The purpose of this report is to summarize current urethral pathophysiology evidence and outline directions for future resea...

A case of urethral hemangioma in a 61-year-old female is reported. She had the complaint of urethral bleeding and difficulty on urination since November 2, 1986. Physical examination revealed a reddish colored, thumb-head sized tumor at the external urethral meatus. All laboratory tests revealed normal findings. At cystoscopy reddish mucosa was found at the distal urethra. With the preoperative...

Background: In this study, cases with suspected urethral condylomata acuminata were examined by dermoscopy, in order to explore an effective method for clinical. oBjective: To study the application of dermoscopy image analysis technique in clinical diagnosis of urethral condylomata acuminata. Methods: A total of 220 suspected urethral condylomata acuminata were clinically diagnosed first with t...
