PURPOSE Most men with benign prostatic hyperplasia (BPH) have bothersome lower urinary tract symptoms (LUTS). This study aimed to investigate the safety and efficacy of high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) for the treatment of BPH in men with detrusor underactivity (DU). MATERIALS AND METHODS From March 2009, 371 patients with BPH were divided ...

PURPOSE Though urodynamic study (UDS) is the current established standard to distinguish between detrusor underactivity (DU) and bladder outlet obstruction (BOO), concerns of patient discomfort and potential complications of catheterization deters its use. We inspected clinical variables to discriminate between DU and BOO in uroflowmetry, which can be more easily performed in clinical practice....

OBJECTIVE To analyze the underlying lower urinary tract dysfunctions by video-urodynamic studies in men who have persistent storage symptoms after initial drug therapy for lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). METHODS The medical records of 614 men ≥40 years of age with LUTS and an International Prostate Symptom Score of ≥8 were retrospectively ...

The longevity of the world's population is increasing, and among male patients, complaints of lower urinary tract symptoms (LUTS) are growing. Testing to diagnose LUTS and to differentiate between the various causes should be quick, easy, cheap, specific, not too bothersome for the patient, and noninvasive or minimally so. Urodynamic evaluation is the gold standard for diagnosing bladder outlet...

OBJECTIVES Benign prostatic hyperplasia (BPH) is considered a frequent cause of bladder outlet obstruction (BOO) and lower urinary tract symptoms (LUTS), although the physiopathologic mechanism through which BPH causes LUTS is not clear. Several morphologic and functional modifications of the bladder detrusor have been described in patients with BPH and could play a direct role in determining s...

OBJECTIVE Pressure-flow study is the gold standard for diagnosis of bladder outlet obstruction (BOO). A prospective study was carried out to compare urodynamic evaluation and measurement of intravesical protrusion of the prostate for diagnosing BOO. MATERIALS AND METHODS Patients presenting with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia and suspected BOO...

OBJECTIVES The aim of this prospective study was to compare the diagnostic accuracy of detrusor wall thickness (DWT), free uroflowmetry, postvoid residual urine, and prostate volume (index tests) with pressure-flow studies (reference standard) to detect bladder outlet obstruction (BOO) in men. METHODS During a 2-yr period, men older than 40 yr with lower urinary tract symptoms and/or prostati...

PURPOSE The present study was done to define the degree of intravesical prostatic protrusion (IPP) causing bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH)/lower urinary tract symptoms. MATERIALS AND METHODS We retrospectively evaluated 239 patients with BPH, analyzing age, IPP, prostate volume, International Prostate Symptom Score (IPSS), and the results f...

Objective: Underactive bladder (UAB) is receiving increased attention as a contributor to urinary bother. An emerging definition of UAB focuses on voiding symptoms suggestive of urodynamic detrusor underactivity. However, while animal and tissue studies are useful to elucidate pathophysiologic mechanisms, they cannot directly address human symptoms. Objective dysfunctions associated with UAB sy...

12 Boötis is a spectroscopic binary whose visual orbit has been resolved by interferometry. Though the physical parameters of the system have been determined with an excellent precision, the theoretical modelling of the components is still uncertain. We study the capability of solar-like oscillations to distinguish between calibrated models of the system obtained by including in the stellar mod...
