OBJECTIVE: To assess the clinical efficacy of sildenafil and the potential predictors of poor response to sildenafil in elderly patients with erectile dysfunction (ED). PATIENTS AND METHODS: The study included 162 patients (aged > or = 60 years) treated with sildenafil for at least 8 weeks; all patients were evaluated with a history, physical examination, measurement of total testosterone and a pharmacological erection test. Sexual function before and 8 weeks after treatment was assessed using t

INTRODUCTION: It has been shown that the Rho/Rho kinase calcium sensitizing pathway has been implicated in the pathogenesis of erectile dysfunction as well as systemic atherosclerosis. AIMS: To test whether chronic treatment of an oral Rho kinase inhibitor (fasudil, 5-Isoquinolinesulfonyl homopiperazine) could prevent the development of both vasculogenic erectile dysfunction and pelvic atherosclerosis in a rat model. METHODS: Rats (3 months old) were divided into three groups (N = 10 in each gro

We investigated the effects of systemic modulation of angiotensin 2 on the erectile dysfunction of aged rats. Young and aged (18 months old) male Sprague-Dawley rats were either treated with daily administration of losartan (angiotensin type 1 receptor antagonist, 30 mg/kg/d PO) or the drug vehicle (control) for 4 weeks (n=6 in each group). We monitored the intracavernosal pressure (ICP) after administration of apomorphine (100 microg/kg), and we measured the degree of lipid peroxidation of corp

The history of treatment for cryptorchidism dates back more than 200 years. This review is intended to highlight some historical aspect that led us to our current surgical treatment of this condition. The medical and historical surgical literatures pertaining to cryptorchidism were reviewed. Data sources were PubMed, Embase, conference proceedings, and bibliographies. No language, date, or publication status restrictions were imposed. The study of cryptorchidism began with the anatomical descrip

Various perceived barriers were identified in those who need IC and differences were demonstrated over time. Both dedicated space and time are issues. In addition, patients may benefit from emotional support and enhanced communication with community agencies and government to resolve the problems related with privacy.

These results indicated that the surgical difficulty of microsurgical subinguinal varicocelectomy was similar between adults and children. The lack of gubernacular vein enlargement in prepubertal boys may suggest the sparing of testicular delivery in this population.

To describe how to perform urological evaluation in children with tethered cord syndrome (TCS). Although a common manifestation of TCS is the development of neurogenic bladder in developing children, neurosurgeons often face difficulty in detecting urological problems in patients with TCS. From a urological perspective, diagnosis of TCS in developing children is further complicated due to the differentiation between neurogenic bladder dysfunctions and transient bladder dysfunctions owing to deve

Background. The study assessed whether measurement of urinary biomarkers of acute kidney injury could be helpful in diagnosing acute pyelonephritis and subsequent scarring. Method. Escherichia coli J96 (0.3 mL inoculum containing 1 × 10(9)/mL) was directly injected into the renal cortex of 3-week-old female Sprague Dawley rats (n = 20), with saline substituted in a control group (n = 10). Following the injection, urine was collected 2, 7, 14, 28, and 42 days after injection. Urinary neutrophil g
