INTRODUCTION Posterior urethral valve (PUV) is a congenital obstructive defect of the male urethra with an incidence of 1/8,000 to 1/25,000 live births. PUV is the most common cause of lower urinary tract obstruction in neonates. The diagnosis of PUV is usually made early, and PUV cases have rarely been detected in adults. CASE PRESENTATION Here we report the case of a 35 years old man presen...

A bladder neck obstruction was suspected after ultrasound investigation at 16 weeks' gestation. Evaluation of protein content in the amniotic fluid, fetal ascites, and fluid from the overdistended bladder supported the diagnosis. Bladder outflow obstruction in the second trimester of pregnancy was not associated with raised alphafetoprotein levels in the amniotic fluid and maternal serum.

Lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) are common problems in aging males worldwide. The objective of this work was to evaluate the effects of bladder neck nerve damage induced by partial bladder outlet obstruction (PBOO) on sensory innervation of the corpus cavernosum (CC) and CC smooth muscle (CCSM) using a rat model of PBOO induced by a partial ligation of the blad...

To analyze the urinary biomarkers in men with lower urinary-tract symptoms (LUTS) and identify interstitial cystitis/bladder pain syndrome (IC/BPS) from other dysfunctions (LUTDs) by levels of characteristic biomarkers. In total, 198 LUTS were prospectively enrolled urine samples collected before intervention or medical treatment. Videourodynamic studies routinely performed LUTDs diagnosed as h...

Aims of course/workshop Detrusor underactivity has gained increasing scientific and clinical interest lately, as it became obvious that a substantial number of female or male patients suffer of this bladder condition. However, no consensus on the diagnosis or evaluation approach has been reached. The key speakers of this workshop are intensively involved in new research initiatives within this ...

OBJECTIVE To analyze the lower urinary tract symptoms (LUTS) and video-urodynamic characteristics of women with clinically unsuspected bladder outlet obstruction (BOO). METHODS From 1997 to 2010, a total of 1605 women with bothersome LUTS received video-urodynamic study in our unit. We reviewed the charts of 212 women diagnosed with BOO based on video-urodynamic criteria and 264 women without...

introduction bladder stone is the most common form of lower urinary tract stones and constitutes 5% of all urinary tract stones. the giant bladder stones are very rare and our report was the first one in iran and in the world. case presentation the patient was a 35-year-old man who was referred to our urology clinic with the lower urinary tract symptoms. irritative symptoms were dominant withou...

pyelonephritis. Resolution was not possible in the presence of an enlarged prostate and an indwelling catheter as reinfection of the kidneys was inevitable; Cases 3, 5, i and 12 survived because the urinary obstruction was removed and the drainage tubes discarded. Infection recurred in Cases 3 and 5 because the chronically distended bladder had not had time to contract down sufficiently and com...

To date, stem cell therapy for the bladder has been conducted mainly on an experimental basis in the areas of bladder dysfunction. The therapeutic efficacy of stem cells was originally thought to be derived from their ability to differentiate into various cell types. Studies about stem cell therapy for bladder dysfunction have been limited to an experimental basis and have been less focused tha...

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...
