Background: Currently, the diagnostic ability of uroflowmetry, the most widely used urodynamic test available for initial assessment of patients with lower urinary tract symptoms (LUTS), is considered limited by its inability to accurately discriminate between the underlying mechanisms of this condition. To improve the diagnostic accuracy of uroflow, we developed a mathematical formula that calculates the flow resistive forces index (QRF), a novel measure of bladder outflow/urethral resistance, and assessed its clinical applicability compared to the maximum flow rate (Q ).

Materials And Methods: A cross-sectional observational study was conducted in a cohort of 61 adult men presenting with voiding dysfunction symptoms, who all underwent free uroflowmetry followed by pressure flow study.

Penile fracture is a very rare urological emergency resulting from traumatic rupture of the tunica albuginea of one or both corpora cavernosa, usually during sexual intercourse. Immediate surgical treatment is the current standard of care with lower risks of late complications, including erectile dysfunction, penile curvature, and tunical scar formation. We, hereby, report an over delayed presentation (23 days) of a penile fracture, which was successfully managed surgically.

Introduction: We developed a mathematical "prostate cancer (PCa) conditions simulating" predictive model (PCP-SMART), from which we derived a novel PCa predictor (prostate cancer risk determinator [PCRD] index) and a PCa risk equation. We used these to estimate the probability of finding PCa on prostate biopsy, on an individual basis.

Materials And Methods: A total of 371 men who had undergone transrectal ultrasound-guided prostate biopsy were enrolled in the present study.

Objectives: To report on the efficacy and safety of augmentation phalloplasty procedures in physically normal young men, to introduce a patient selection and outcome evaluation questionnaire as well as, to propose a surgical technique modification.

Methods: Eleven (11) out of 28 psychosomatically normal men (25-35 years) who presented complaining of penile dysmorphophobia (subjective perception of small penis), were subjected to: (a) penile lengthening (suprapubic skin advancement--ligamentolysis): n=5, (b) penile lengthening and shaft thickening (free dermal-fat graft shaft coverage): n=3 and (c) panniculectomy--suprapubic lipectomy and penile lengthening: n=2. A self administered questionnaire was employed in order to facilitate selection of the patients qualifying for the operation as well as to evaluate the outcome.

Objectives: To estimate the sizes of the external genital organs in physically normal adult males younger than 40 years old, as well as to correlate the resulting values with age and a number of somatometric parameters, to provide data that could be clinically applicable by the practicing urologist.

Methods: Fifty-two physically normal men, 19 to 38 years old, underwent tape measurements of penile dimensions in the flaccid-stretched state (total, shaft, glanular lengths), penile shaft volume calculation, and ultrasonographic testicular volume estimation. The resultant values were correlated with age, height, weight, body mass index, waist/hip ratio, and index finger length.
