External urethral sphincter electromyography (EMG) during bladder filling was quantitatively analysed using automatic decomposition electromyography (ADEMG). These include 7 normal volunteers, 7 patients with outlet obstruction, 9 with sphincter dyssynergia, and 7 with pelvic nerve injury (PNI). Recruited number of participated motor unit action potentials (MUPs) at maximum bladder filling was ...

We present the case of a 13-year-old boy with a congenital anterior urethral diverticulum. This is a rare condition in males which can lead to obstructive lower urinary tract symptoms and urosepsis. Diagnosis is by urethroscopy and radiological imaging. Surgical treatment can be open or endoscopic. Long-term followup is required to check for reoccurrence of the obstruction.

PURPOSE Detrusor-sphincter dyssynergia is a common cause of bladder outlet obstruction in spinal cord injured patients and leads to poor bladder emptying and high bladder pressures, which if left untreated might cause renal failure. In this study, we tested the recently published hypothesis that oral administration of a nitric oxide donor could be a new pharmacological approach to treat detruso...

AIM To compare the use of the suprapubic puncture method versus the transurethral method in pressure-flow studies in patients with benign prostatic hyperplasia. METHODS Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, en...

INTRODUCTION A distended urinary bladder has been known to cause venous obstruction or rarely bowel obstruction. We report the first case in the literature in which urinary bladder distension presented with both venous obstruction and constipation. This is an unusual presentation of urinary bladder distension and serves to broaden our differential diagnoses for a patient with clinical venous ob...

Nemaline myopathies (NMs) are a group of congenital muscle diseases caused by mutations in at least 10 genes and associated with a range of clinical symptoms. NM is defined on muscle biopsy by the presence of cytoplasmic rod-like structures (nemaline rods) composed of cytoskeletal material. Myofiber smallness is also found in many cases of NM and may represent a cause of weakness that can be co...

OBJECTIVE Chronic renal failure due to tubulointerstitial fibrosis is one of complications of lower urinary tract obstruction. Since pentoxifylline is a xanthine derivative that inhibits some inflammatory mediators, we conducted this study to investigate whether pentoxifylline inhibits renal fibrosis in a rat model of partial urethral obstruction (PUO). METHODS All the rats underwent experime...

classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. from 1981 through 1988,21 boys with history of posterior urethral valve (puv) underwent evaluation for vesicoureteral (vu) reflux 17 boys had vu reflux. following valve ablation, reflux disappe...

The role of VCU in the management of various urological conditions was discussed after retrospectively analyzing 197 voiding cysto-urethrograms performed on 167 cases. 1) The normal voiding is initiated when the base plate breaks open by virtue of its own contraction and continues smoothly while detrusor contraction follows toward the trigonal canal which is progressively transformed from the b...
