Abstract:

Birth trauma and pelvic injury have been implicated in the etiology of stress urinary incontinence (SUI). This study aimed to assess changes in the biomechanical properties and adrenergic-evoked contractile responses of the rat urethra after simulated birth trauma induced by vaginal distension (VD). Urethras were isolated 4 days after VD and evaluated in our established ex vivo urethral testing system that utilized a laser micrometer to measure the urethral outer diameter at proximal, middle, and distal positions. Segments were precontracted with phenylephrine (PE) and then exposed to intralum

Abstract:

Stress urinary incontinence (SUI) is the involuntary release of urine during sudden increases in abdominal pressures. SUI is common in women after vaginal delivery or pelvic trauma and may alter the biomechanical properties of the urethra. Thus we hypothesize that injury due to vaginal distension (VD) decreases urethral basal tone and passive stiffness. This study aimed to assess the biomechanical properties of the urethra after VD in the baseline state, where basal muscle tone and extracellular matrix (ECM) are present, and in the passive state, where inactive muscle and ECM are present.

The urethra is part of the lower urinary tract and its main role is urine voiding. Its complex histological structure makes urethral tissue prone to various injuries with complicated healing processes that often lead to scar formation. Urethral stricture disease can affect both men and women. The occurrence of this pathology is more common in men and thus are previous research has been mainly oriented on male urethra reconstruction.

In male urethan-anesthetized rats, activity was measured in nerves that run over the proximal urethra. The urethral nerve response to stepwise urethral perfusion could be described by a four-parameter model (fit error <6%). At the onset of perfusion, the urethra was closed and the pressure increased with the infused volume. The nerve activity (NA) increased linearly with this inserted volume to a maximum (NAmax), which was proportional to the instantaneous pressure. The duration of this first episode (δ t) was inversely proportional to the perfusion rate. After infusion of a fixed volume, t

Many patients with this malformation are asymptomatic. Some patients may complain of intermittent discharge from the accessory urethra, incontinence, infection, double streams or stricture. The duplicated urethra may be complete or incomplete, may be located dorsal, ventral or in Y-type. The treatment of urethral duplication is individualized, depending on the t

Urethral strictures represent the intrinsic and permanent narrowing of the urethral lumen with urodynamic effects and genitourinary complications resulting from obstruction in the path of urine and seminal fluid elimination. In men, urethral stricture refers to a narrowed segment of the anterior urethra caused by a process of fibrosis and scarring of the urethral mucosa and surrounding spongiosum tissue ("spongiofibrosis"). In the male posterior urethra, there is no spongiosum tissue, and the term stenosis is preferred in this location. The definition of meatal stenosis is accepted as a distal

After urethral healing, a solution of Mitomycin C (40 mg/80 cc) was instilled into the urethra for fifteen minutes and held in place with a penile clamp. Urethral instillations were repeated weekly for six weeks. The patient is currently disease-free more than one year and three months posttreatment. This

Penile fracture is not uncommon blunt trauma to the penis. Here, we present a rare case of penile fracture during sexual intercourse. The patient presented with penile swelling, bleeding per urethra, and inability to pass urine. Retrograde urethrogram showed significant extravasation of contrast from anterior penile urethra and no contrast passing to proximal urethra. Surgical exploration showed complete urethral rupture and bilateral cavernosal rupture. This case represents the value of urethrogram to evaluate the urethral injury and the association of complete urethral injury with bilateral

Abstract:

In general, the term urethral stricture refers to a fibrous scarring of the urethra caused by collagen and fibroblast proliferation.1-3 The scarring process can extend through the tissue of the corpus spongiosum into adjacent structures and this associated scarring in the surrounding corpus spongiosum is known as spongiofibrosis.1,4 Contraction of this scar reduces the width of the urethral lumen. Bulbar urethral strictures represent the overwhelming majority of cases, while prostatic urethral strictures are rare.5 The causes of anterior urethral strictures may be inflammatory (e.g., infectiou

AbstractDuplication of the urethra is a rare congenital anomaly, with approximately 300 cases reported in the literature. We report a unique case of this condition in a male infant. This case differs from the classical Effman type II-A2 duplication because of the presence of two hypospadic urethral meati, as opposed to a ventral or dorsal accessory meatus with a normally positioned distal urethra. The patient underwent a single-stage repair consisting of a proximal urethra-urethral anastomosis and distal urethral tubularization at 21 months of age with excellent results in terms of both functi

To clarify how PGE2 reduces bladder capacity, 100 µM PGE2 was administered intravesically during open, single-fill cystometry with simultaneous measurement of sphincter EMG in the urethane-anesthetized female Wistar rat.

AbstractWhales are mammals that can dive to depths of > 1000 m without the high water pressure pushing open their mouth or anus. The same is true for the female urethra. The meatus externus and internus are seals that cannot be pushed open by high water pressures. Recent evidence suggests that the female meatus internus is pushed open when the bladder pressure exceeds the urethral pressure. For a relaxed detrusor, this opening is not possible for at least three reasons: the law of elastic collision, Pascal’s law of hydrostatics and the Hagen-Poiseuille law.

Urethral doubling is a rare congenital anomaly of the urinary system that is more common in boys. Less than 500 clinical cases of this disease have been described in the literature, which may signal a lack of awareness among physicians. Although there are many considerations regarding the embryology of this anomaly, the etiopathogenesis of its various forms remains unclear. Sometimes doubling of the urethra is combined with other malformations, such as epispadias, hypospadias, exstrophy of the bladder, anorectal malformation, doubling of the bladder and others.
