Anterior urethral valves is a very rare congenital anomaly of the anterior urethra. It produces symptoms of varied intensity with the most severe ones leading to Urosepsis and renal failure (similar to as in posterior urethral valves) to the milder ones which may not produce any obstruction at all. However unlike the Posterior urethral valves this anomaly has milder and reversible sequelae in m...

Most childhood obstructive lesions are congenital, although urinary tract obstruction can be caused by trauma, neoplasia, calculi, inflammatory processes, or surgical procedures. Obstructive lesions occur at any level from the urethral meatus to the calyceal infundibula (Table 540-1). The pathophysiologic effects of obstruction depend on its level, the extent of involvement, the child’s age at ...

Cystography was performed on 35 patients 6 to 7 days after retropubic radical prostatectomy (RRP), to determine the feasibility of early removal of the urinary catheter. The urethral catheter was removed the same day if no extravasation was evident on cystography. Uroflowmetry was also performed both immediately after early catheter removal and at follow-up 4 to 20 months later. The urethral ca...

Neurourology is applicable to urinary incontinence and obstructive uropathy in the general population. In most neurogenic conditions, incontinence is related to a loss of coordination of the bladder with the urethral sphincter mechanism. This article discusses possible causes and risk factors for stress incontinence and gives several clinical examples of patients with incontinence of varying ca...

INTRODUCTION We face continuing challenges for the optimal form of treatment for stress urinary incontinence (SUI). Long-term outcome studies have revealed disappointing results for percutaneous needle suspensions and other sling substitutes secondary to failure due to the recurrence of urethral hypermobility or creation of urethral obstruction 1. The pubovaginal sling procedure is an establish...

Nitric oxide (NO) has been proposed to function as an inhibitory neurotransmitter in the lower urinary tract. This study investigates the distribution of NO-containing neurons and its changes following urethral obstruction in the guinea-pig. By using nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) histochemistry and NO synthase (NOS) immunohistochemistry, the highest frequency ...

There are few cases reporting urinoma secondary to posterior urethral valve (PUV) in literature. Urinoma secondary to a pelvi ureteric junction (PUJ) obstruction is very rare. We report a newborn with urinary ascites in whom both PUV and PUJ obstruction co-existed causing a diagnostic dilemma.

Benign prostatic hyperplasia (BPH) is typically a disease of men aged 40 years, and above. By the age of 50 years, approximately 20% of men are affected, while by the age of 75 years, approximately 75% of men are affected. Given this incidence, and the aging population, BPH has become a major health care issue. The pathology of BPH is induced by a hyperplastic prostate occluding the bladder out...

AIMS To determine if detrusor glycogen content in a bladder after removal of a urethral obstruction reflects the situation of bladder dysfunction as it existed during the period of obstruction. METHODS The glycogen content of the detrusor was scored using a Periodic Acid Schiff's (PAS) staining. It was related to the functional history of the bladder. Bladder tissue was obtained from a guinea...
