Urethral amyloidosis is a rare condition in which eosinophilic amyloid proteins are deposited in the urethra. Only a small number of reports on urethral amyloidosis have been published. Increased interest has been associated with this disease due to its clinical similarities with urothelial carcinoma. A biopsy of the lesion and a histological examination are essential for the correct diagnosis....

We experienced the growth of urethral hair along the urethral stricture six years after simultaneous urethral repair and reimplantation of penile prosthesis (RPP) in a patient with a urethral stricture. We detected hair in the urethra with a stricture on the bulbous urethra. Further, we performed hair removal by using a pair of cystoscopic forceps and internal urethrotomy. Then, we performed RP...

Stress urinary incontinence (SUI) is a debilitating disorder caused by malfunctioning of the urethral sphincter. Anatomical and histological properties of the sphincter, its innervation and supporting structures are explained in relation to the closing mechanism of the bladder outlet. Urethral sphincter function is discussed from the passive concept of urethral pressure transmission to the 'ham...

In this study, we examined the possibility that 5-HT1A receptors may underlie sexually dimorphic mechanisms affecting the regulation of urethral functions in anesthetized rats. Simultaneous recordings of intravesical pressure under isovolumetric conditions, external urethral sphincter-electromyography, and urethral perfusion pressure were used to examine the effects of a 5-HT1A receptor agonist...

CONTEXT There is still controversy as to the use and dosage of antimicrobial prophylaxis of the urinary infection associated with urethral catheterization in the post renal transplant period. OBJECTIVE To determine whether patients develop urinary infection during short-term urethral catheterization after renal transplant without routine antimicrobial prophylaxis. DESIGN Prospective study. ...

Urethral mucosa with intestinal metaplasia and dysplasia is a rare occurrence. To date only a single case has been reported in a male with long-standing urethral stricture. We present a 33-year-old female with polypoid intestinal metaplasia and dysplasia of the external urethral meatus in the absence of an inciting factor. Intestinal metaplasia of the urethral mucosa may undergo dysplasia, emph...

Urinary obstruction is one of the causes for the morbidity and mortality, if not treated in early stages in small ruminants. Goats are more susceptible for incidence of urethral caliculi as these species having urethral process where the urethral diameter is narrowed and leads to urinary obstruction. If the condition initially not identified later bladder will rupture and leads uroabdomen. The ...

Primary urethral calculus is rarely seen and is usually encountered in men with urethral stricture or diverticulum. We present a case of giant urethral calculus secondary to a urethral stricture in a man. The patient was treated with calculus extraction with end to end urethroplasty.

Background: Initial management of urethral injury remains controversial concerning the use of suprapubic urinary diversion and delayed repair, primary open realignment, and primary endoscopic realignment. To our knowledge, we present the first reported case of a penetrating urethral injury because of an animal attack, without concomitant extragenitourinary system involvement, managed entirely e...
