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...

Umbilical and supraumbilical catheter insertion is a common procedure performed in the NICU. It is a safe and usually easy procedure devoid of serious mishaps, morbidity and mortality. Complications such as hemorrhage, infection, hernia, evisceration, omphalitis, portal vein thrombosis and portal hypertension may occur after umbilical catheter insertion. Other uncommon and rare complications re...

Urinary incontinence is a significant medical problem affecting quality of life in women. Numerous surgical treatment options are available for management of stress urinary incontinence, including urethral bulking agents, pubo-vaginal slings, retropubic bladder neck suspensions, mid-urethral slings, and even artificial urinary sphincters. We will discuss the incidence, etiology, diagnosis, eval...

OBJECTIVES To evaluate relationship between intravesical prostatic protrusion (IPP) on transrectal ultrasonography (TRUS) and pressure-flow study (PFS) findings in patients with benign prostatic obstruction/lower urinary tract symptoms (BPO/LUTS). MATERIAL AND METHODS Between March 2006 and August 2009, we reviewed medical records of 87 patients who were underwent TRUS and PFS for evaluation ...

Posterior urethral valves occur in 1 : 5000 live births. Despite the high prevalence, the few children that survive do poorly, with over 50% progressing to ESRD in 10 years. The gold standard for post-natal diagnosis is voiding cystourethrography, while pre-natal diagnosis is dependent on routine screening ultrasonography. Despite the ability to identify features of bladder outlet obstruction e...

Complex, proximal, anteriorly located urethral diverticula present the reconstructive urologist with a uniquely challenging task for repair through a conventional transvaginal approach. Herein, we present the first report of urethral diverticulectomy to excise a large, anterior, horseshoe-shaped urethral diverticulum that resulted in bladder outlet obstruction, using a transabdominal robot-assi...

In this review, we have looked at three important areas in understanding male lower urinary tract symptoms. These are improvement in terminology, detrusor underactivity, and nocturia. Benign prostatic hyperplasia leading to bladder outlet obstruction has been covered in a previous review.

OBJECTIVES To investigate if the circadian rhythm of urinary flow values varies within groups of patients with varying degrees of bladder outlet obstruction. METHODS A total of 170 patients with lower urinary tract symptoms suggestive of bladder outlet obstruction used a home-based uroflowmeter and produced a total of 1670 correctly measured flows at home. These patients also underwent a scre...

PURPOSE We prospectively examined whether the fixed urethral resistance of the perineal male sling for the treatment of stress incontinence causes significant bladder outlet obstruction or de novo voiding dysfunction. MATERIALS AND METHODS A total of 22 patients (average age 67 years old) were evaluated before and after surgery with videourodynamics, the self-administered UCLA Prostate Cancer...

Synthetic suburethral slings have become the most widely used technique for the surgical treatment of stress urinary incontinence. Despite its high success rates, significant complications have been reported including bleeding, urethral or bladder injury, urethral or bladder mesh erosion, intestinal perforation, vaginal extrusion of mesh, urinary tract infection, pain, urinary urgency and bladd...
