A novel method for evaluating the urethral resistance during abrupt elevation of abdominal pressure was developed in spinalized female rats under urethane anesthesia. Electrical stimulation of abdominal muscles for 1 s induced increases in both the intra-abdominal and the intravesical pressure in a stimulus-dependent manner, and the bladder response was almost lost when the abdomen was opened. ...

We conducted this study to evaluate the combined effect of acellular bladder submucosa matrix (BSM) and autologous urethral tissue for the treatment of long segment urethral stricture in a rabbit model. To prepare the BSM, porcine bladder submucosa was processed, decellularized, configured into a sheet-like shape, and sterilized. Twenty rabbits were randomized to normal control, urethral strict...

Pelvic fracture urethral injuries are typically partial and more often complete disruptions of the most proximal bulbar and distal membranous urethra. Emergency management includes suprapubic tube placement. Subsequent primary realignment to place a urethral catheter remains a controversial topic, but what is not controversial is that when there is the development of a stricture (which is usual...

Posterior urethral valve and vesical calculus are individually among the most common causes of obstructive lower urinary complaints in children. There are very few reports of association between posterior urethral valves and bladder calculus. We report three such cases. This association of the vesical calculi with posterior urethral valves may lead to a delay in the diagnosis of the posterior u...

A 61-year-old male with prior history of endoscopic urethral calculus removal presented to the emergency room with urinary retention and a palpable perineal mass. A CT showed a large calcification within the bulbar urethra. After multiple unsuccessful attempts at foley catheter insertion, the urology service was consulted. The patient was taken to the operating room where an obstructing urethra...

INTRODUCTION We present the first case reported in the medical literature of a patient with a posttraumatic urethral fistula accompanied by retraction urethral catheter with balloon. CASE PRESENTATION A 69-year-old man was admitted to our hospital with the recurrence urinary tract infection. The patient reports history of urethral trauma, which is retraction urethral catheter with balloon 2 y...

bstructive uropathy is a common clinical problem, and urethral calculi constitute the least common form of calculous disease leading to obstructive uropathy. Urethral calculi may originate anywhere in the urinary tract, usually the bladder, and then migrate to the urethra. The clinical presentation is variable. Patients may have acute retention, dysuria, or a weak urine stream.1 Sonography is a...

To the editor: The article by Tan et al. [1] is indeed interesting. This article is one of the rare reports about surgical risk factors associated with urethral stricture (US) occurrence after bipolar transurethral resection of prostate (B-TURP) using the Gyrus PlasmaKinetic Tissue Management System (Gyrus ACMI, Southborough, MA, USA). The results seem some interesting and were consistent with ...

Substitution urethroplasty for the treatment of male stricture disease is often accompanied by subsequent tissue fibrosis and secondary stricture formation. Patients with pre-existing morbidities are often at increased risk of urethral stricture recurrence brought upon in-part by delayed vascularization accompanied by overactive inflammatory responses following surgery. Within the context of th...
