Urinary retention in young children and infancy is relatively rare. The commonest malignancy cause of bladder outlet obstruction in infancy is prostatic rhabdomyosarcoma; the commonest cause of congenital bladder outlet obstruction in a male infantis posterior urethral valve and the commonest cause of urethral obstruction in male children is urethral calculi. We present here a report on three c...

OBJECTIVES Lower urinary tract symptoms (LUTS) are highly prevalent among men; however, not all men with LUTS have urodynamically confirmed bladder outlet obstruction. Overactive bladder symptoms are often caused by bladder dysfunctions alone or in combination with bladder outlet obstruction. A detailed diagnosis to identify the causes of LUTS in men seems mandatory to correctly target differen...

Subcapsular urinomas have been reported in the past as a presenting feature of ureteric or bladder outlet obstruction, generally in children, and often associated with neurogenic bladders. We describe a case of spontaneous asymptomatic bilateral subcapsular urinomas in an adult male with high pressure retention of urine secondary to bladder outlet obstruction. An extensive literature review sho...

Partial bladder outlet obstruction in the rabbit produces changes in bladder function similar to those seen clinically in patients with obstructive uropathies. Whole organ function is significantly altered, as are the smooth muscle cells inside the bladder wall. This study was designed to determine whether outlet obstruction alters smooth muscle function at the level of contractile filaments. R...

PURPOSE We evaluated the urodynamic and clinical effects of terazosin in patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS A total of 45 patients who participated in a multicenter trial was evaluated with urodynamic pressure-flow studies before and after 26 weeks of treatment. RESULTS Maximum flow rate and symptom score improved significantly in 22 patients...

In women, urethral condyloma rarely leads to a bladder outlet obstruction. A 39-year-old woman who presented with frequency, urgency, and residual urine sensation was found to have a condyloma in her urethral meatus. Urodynamic study indicated bladder outlet obstruction. After condyloma excision, she returned to normal voiding, and the free maximum flow rate improved. In women, excision of uret...

BACKGROUND Bladder outlet obstruction is a common urological condition. We aimed to summarize available evidences about bladder outlet obstruction-induced molecular and morphological alterations occurring in human bladder. METHODS We performed a literature search up to December 2017 including clinical and preclinical basic research studies on humans. The following search terms were combined: ...

PURPOSE We describe the pathophysiology, differential diagnosis and urodynamic findings in patients with a large capacity bladder. MATERIALS AND METHODS This was a retrospective, observational study of 100 consecutive patients with voiding dysfunction and a cystometric bladder capacity of greater than 700 ml. Clinical data, cystometric bladder capacity and other urodynamic findings were evalu...

INTRODUCTION Bladder outlet obstruction in younger men is often secondary to urethral stricture disease. In the older population it is often a result of benign prostatic hypertrophy. MATERIALS AND METHODS We describe the diagnosis, treatment, and outcome of a rare case of a Brunn's cyst causing bladder outlet obstruction in a 43-year-old male who was evaluated for obstructive urinary complain...
