During stress-induced increase in abdominal pressure, urinary continence is maintained by urethral closure mechanisms. Active urethral response has been studied in dogs and rats. Such an active urethral response is also believed to occur in humans during stress events. We aimed to investigate urethral closure mechanisms during sneezing in cats. Urethral pressures along the urethra (UP1-UP4), wi...

Urethral duplication is a very rare congenital anomaly. Urethral duplication is seen most commonly in the sagittal plane. We report a rare case of complete urethral duplication in the coronal plane with no other associated anomalies. Surgical correction of this coronal urethral duplication resulted in a normal-appearing penis and good functional outcome with a single midline urethral meatus and...

PURPOSE We assessed the use of urethral pressure reflectometry in detecting pressure increases in the female urethra and compared the usefulness of urethral pressure reflectometry vs urethral pressure profilometry in a pharmacodynamic intervention study. MATERIALS AND METHODS In this randomized, double-blind, placebo controlled, crossover study 17 women with stress urinary incontinence or mix...

This report highlights a presentation of urinary calculus impacted at the urethral meatus and bedside extraction after evaluation with point-of-care ultrasound (POCUS). Visualization of a stone at the urethral meatus prompted a point-of-care ultrasound of the penile shaft and glans. The ultrasound ruled out anatomic variations such as urethral diverticula and as a result bedside removal was exp...

INTRODUCTION Urethral caruncles usually arise from the posterior lip of the urethral meatus. Although the etiology of urethral caruncles is still undetermined, they are the most common benign tumors of the female urethra. Most cases are frequently asymptomatic, but, sometimes patients feel a lump or bleeding at the urethral meatus. Symptoms are dysuria, dyspareunia, hematuria and rarely asensat...

Tissue engineering-based urethral replacement holds potential for repairing large segmental urethral defects, which remains a great challenge at present. This study aims to explore the potential of combining biodegradable poly(l-lactide) (PLLA)/poly(ethylene glycol) (PEG) scaffolds and human amniotic mesenchymal cells (hAMSCs) for repairing urethral defects. PLLA/PEG fibrous scaffolds with vari...

Urethra Secondary cancer Urethral caruncle Abstract Secondary female urethral cancer presenting as urethral caruncle is extremely rare. We report a primary ovarian adenocarcinoma in a 78-year-old female patient presented initially as a urethral caruncle. This case represents the first reported case in the world literature. The clinical features, investigations and pertinent literature are revie...

PURPOSE We report the efficacy of an expanded algorithm for penile straightening in proximal hypospadias surgery to preserve the urethral plate for urethroplasty. We also compared ventral corporotomy with grafting to multiple superficial ventral corporotomies without grafting for straightening greater than 30-degree ventral curvature. MATERIALS AND METHODS The need for urethral plate transect...

The present study nicely presents the authors’ experience in carrying out two different variations on repair of long anterior urethral strictures, a condition that can be difficult to treat. The prospective, randomized design confers credibility to their outcomes. They randomized a reasonable number of patients, and followed their patients for at least a year. Based on the welldefined success r...

background: the normal prostate-specific antigen (psa) level in patients with urethral catheterization is a controversy. we designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum psa. materials and methods: seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in th...
