Amyloidosis of the urethra is a rare disease. The clinical appearance resembles carcinoma of the urethra, so that biopsy is required to make the appropriate diagnosis. Once primary localized amyloidosis of the urethra has been diagnosed, selection of the appropriate treatment for each case becomes important. We report a case of primary localized amyloidosis in the male anterior urethra. This ca...

Urethral duplication is a rare congenital anomaly. We report a 6-year-old male with type IIA2 (Y-type) using Effmann's classification. The accessory urethra, in which a urinary stone existed, arose from the posterior urethra to the scrotum. Because of recurrent urinary tract infection and urinary discharge from the accessory urethra, surgical removal of the accessory urethra through a scrotal i...

The proximal urethra and urinary bladder trigone play important roles in continence. We have previously shown that PGD2 is released from guinea pig bladder urothelium/suburothelium and can inhibit detrusor contractile responses. We presently wished to investigate PGD2 actions in guinea pig out-flow region and the distribution of DP1 /DP2 receptors. The effects of PGD2 on urothelium-intact trigo...

OBJECTIVE To describe the distribution of elastic fibres in the developing male urethra and to provide stereological data of the concentration of elastic fibres in the human urethra. MATERIALS AND METHODS Urethras were obtained from 10 fresh normal human fetuses at 15-36 weeks of gestation. A place-matched spongy urethra of a 27-year-old normal adult man was also analysed. Samples were fixed ...

Introduction: The aim of this study was to evaluate the diagnostic value of antegrade flexible cystoscopy in pelvic fracture urethral distraction defects (PFUDD). Materials and Methods: Between 1999 and 2004, a total of 111 patients with PFUDD were evaluated by antegrade flexible cystoscopy. The flexible cystoscope was introduced into the posterior urethra and the area was evaluated for any pro...

conclusions silodosin use prior to vcug confers a statistically significant increase in bladder neck opening and visualization of posterior urethra. results in group a 19 out of 20 patients were able to achieve satisfactory bladder neck opening while in group b 10 out of 15 patients were able to achieve bladder neck opening. patients and methods patients were divided into two groups a and b con...

Duplication of the urethra is a rare congenital anomaly. Urethral duplication with the presence of diverticulum is a rare combination and to the best of our knowledge has  not been previously reported. We report a case of a 16 month old male child with duplication of the urethra and diverticulum arising from the ventral urethra. We also cover the intricacies and challenges in the management of ...

BACKGROUND We report our results after 100 urethroplasties for the treatment of urethral stricture both at the bulbar and penile urethra, using different techniques. METHODS 100 patients with the diagnosis of anterior urethral stricture, that were submitted for urethroplasty in the period 1997-2007. Of them, 57 treated by end to end urethroplasty. 4 patients underwent augmented free graft ana...

PURPOSE The resistance offered to urinary flow by the urethra is one of the factors determining the course of micturition. It was the aim of the present work to study the dependence of urethral resistance on the degree of relaxation of the urethra. MATERIALS AND METHODS Experiments were done in the guinea pig. Ten animals were used. In 5 animals saline was forced through the (unrelaxed) ureth...

Diphallia is an extremely rare embryological anomaly, occurring once in 5–6 million births. Here we discuss a neonate who was referred for surgical consultation of diphallia, which examination revealed dominant right phallus and apparently shorter left phallus. MRI retrograde urethrogram unique pathway the urethra stenosed, but otherwise normal urethra. The decision made to excise associated du...
