Objectives. To evaluate the use of interposition flaps in repairing vesicovaginal fistulas (VVFs) of benign and malignant etiologies. Interposition flaps are not routinely used in the repair of VVFs when the surrounding tissues appear healthy and well-vascularized, such as in a benign etiology.Methods. We retrospectively reviewed the charts of 37 women(More)
PURPOSE We evaluated ejaculatory response and semen quality in 653 trials of penile vibratory stimulation in 211 men with spinal cord injury, and compared results with low versus high amplitude vibratory stimulation. MATERIALS AND METHODS Low and/or high amplitude penile vibratory stimulation was performed 1 to 27 times in each patient, and antegrade and(More)
PURPOSE Since the introduction of prostate specific antigen (PSA) screening, asymptomatic men often undergo transrectal ultrasound guided prostate biopsy. This procedure may cause significant discomfort, which may limit the number of biopsies. We performed a randomized prospective study to compare periprostatic infiltration with 1% lidocaine with(More)
The semen of most men with spinal cord injury (SCI) contains sperm with abnormally low motility. Studies suggest that the seminal plasma is the source of this condition. The seminal plasma of men with SCI contains an abnormally high number of white blood cells (WBC), specifically, activated T cells. It is known that activated T cells secrete cytokines and(More)
PURPOSE Recent evidence suggests that the seminal plasma of spinal cord injured men contributes to their distinctive semen profile of normal sperm concentration but low sperm motility and viability. This finding indicates that sperm in these men may be normal before exposure to the seminal and prostatic fluids. To investigate this question we compared vas(More)
Most men with spinal cord injury (SCI) are infertile. Erectile dysfunction, ejaculatory dysfunction and semen abnormalities contribute to the problem. Treatments for erectile dysfunction include phosphodiesterase type 5 inhibitors, intracavernous injections of alprostadil, penile prostheses, and vacuum constriction devices. In anejaculatory patients who(More)
PURPOSE In what is to our knowledge the largest study of its kind to date we retrospectively reviewed the records of 3,152 semen retrieval procedures in a total of 500 men with spinal cord injury to make recommendations to the medical field on ejaculatory dysfunction treatment in this specialized patient population. MATERIALS AND METHODS We(More)
PURPOSE Based on the findings of a previous study of pressure differentials in the external and internal urinary sphincters during electroejaculation we determined whether semen retrieval in men with spinal cord injury would be improved by interrupting current delivery during electroejaculation. MATERIALS AND METHODS We tested continuous versus(More)
Standard clinicopathological variables are inadequate for optimal management of prostate cancer patients. While genomic classifiers have improved patient risk classification, the multifocality and heterogeneity of prostate cancer can confound pre-treatment assessment. The objective was to investigate the association of multiparametric (mp)MRI quantitative(More)
Normal sexual and reproductive functions depend largely on neurological mechanisms. Neurological defects in men can cause infertility through erectile dysfunction, ejaculatory dysfunction and semen abnormalities. Among the major conditions contributing to these symptoms are pelvic and retroperitoneal surgery, diabetes, congenital spinal abnormalities,(More)
