Introduction: The effects of besipirdine and its main metabolite, HP-748, as well as duloxetine and tomoxetine in the lower urinary tract (LUT) were studied using in vitro and in vivo techniques.

Materials And Methods: For in vivo studies, besipirdine or duloxetine effects on cystometric parameters and striated sphincter electromyographic (SS-EMG) activity were investigated. On the isolated urethra, norepinephrine (NE) concentration-response curves (CRC) were performed in the presence of besipirdine, duloxetine or tomoxetine.

Objectives: Renal haemangiomas of renal papillary or medullar origin are a difficult diagnosis entity, being one of the most frequent processes of chronic episodes of hematuria, secondary to benign disease, mainly in young patients. The objective of this paper is to show the difficulty of this diagnosis and the need to suspect it in cases with clinical history similar to the ones described in these cases.

Methods: We report 4 cases of spontaneous hematuria of renal origin, with clinical presentation as renal colic, from the historical case series of the Fundacion Jimenez Díaz-Capio, the last two from the years 2005-6.

Combined immunodetection of parathyroid hormone-related protein (PTHrP) and receptor activator of NF-kappaB ligand (RANKL) has shown to successfully distinguish poorly- and well-differentiated prostate carcinoma (PCa). In the present study, we aimed to assess whether immunohistochemical evaluation of these factors, and also osteoprotegerin (OPG) and Ki67, in radical prostatectomy specimens can predict biochemical recurrence. Fifty nine PCa cases undergoing radical prostatectomy between 1995 and 1998, without history of neoadjuvant hormonal therapy, were studied.

Permanent drainage of the urinary tract by catheters or tubes causes bacteriuria. The potential harmful effects of the indwelling catheter's bacteriuria are related to: time since the insertion of the catheter; location of the catheter (urethra, bladder, kidney); catheter composition (latex, silicone, etc.); type of ineffective bacteria and specific pathogenic mechanisms; health status of the urinary tract being drained (prior radiation therapy, tumors, etc.

In the Middle Ages medical texts the notes about personal hygiene are scarce and they are dedicated to the Kings or the aristocracy. In his work Regimen sanitatis ad inclytum regen Aragorum, Amaldo de Vilanova underlines six things that are necessary for cleanliness, among which he includes his well-known proposition Conservatio juventute preservatio senectute. We compared his text with those from other authors with references to the issue and, once examined, Vilanova's work stands out.

Updated critical review of chronic prostatitis as a nosologic, anatomic-clinical entity of supposed microbiological or inflammatory origin. Scientific reasoning about the role of amicrobial inflammation in both caudal and cranial prostate, after new progresses, to reconsider the convenience of maintaining the current classification of chronic prostatitis, mainly in the section referred to "histological prostatitis". Analysis of scientific evidences relating prostatitis and "pelvic pain", the dominant syndrome in many patients and basement of the current terminological proposal: prostatitis-pelvic pain.

Objective: Serotonin and norepinephrine systems are involved in the neural control of lower urinary tract function. The aim of this study was to compare the response on striated anal sphincter electromyographic (SAS-EMG) activity and cystometric parameters, when duloxetine and clomipramine were intravenously administrated.

Methods: The effects of intravenous 1 and 2 mg.

Objectives: This paper profiles the usage and effectiveness of various LUTS/BPH drugs in real-life practice.

Method: The TRIUMPH study recorded the treatment and outcomes of 2351 newly-presenting LUTS/BPH patients in 6 European countries over a 1-year follow-up period. At each visit the clinician recorded the treatment, co-morbidities, complications and drugs prescribed, and the patient completed an IPSS questionnaire.

Aim: To investigate multiple bone cytokines produced by prostate carcinoma (PCa) as a novel strategy to differentiate potential aggressiveness in localised PCa using immunohistochemical analysis.

Methods: A total of 47 cases of PCa undergoing radical prostatectomy or transurethral prostatic resection at our institution (Fundación Jiménez Díaz (Grupo Capio), Madrid, Spain) between January 1991 and June 1998 were identified as low-grade (< or =4; n = 22) or high-grade (> or =7, excluding 7 (3+4) cases; n = 25) PCa according to Gleason grade. PCa specimens were immunostained for: parathyroid hormone (PTH)-related protein (PTHrP), the PTH1 receptor, osteoprotegerin and receptor activator of nuclear factor-kappa B ligand (RANKL), as well as Ki67 (a proliferation marker) and CD34 (an angiogenesis marker).

This report reviews the diagnostic and prognostic importance of the pathologic findings in prostate needle biopsies. The morphological findings of the needle biopsy may be placed into one of the following five categories: prostate cancer, atypical small acinar proliferation, high-grade prostatic intraepithelial neoplasia, inflammation, and benign prostatic tissue. While the prime goal of the biopsy is to diagnose prostatic adenocarcinoma, once carcinoma is detected, further descriptive information regarding the type, amount of cancer, and grade forms the cornerstone for contemporary management of the patient and for assessment of the potential for local cure and the risk for distant metastasis.

Objectives: Upper urinary tract videourodynamic studies were first described in the second half of the 20th century (years 60-70). The antegrade pyelogram with constant pressure and controlled flow received the name of its author, "Vela Navarrete test" (1982), who currently refers to it as video-urodynamic study of the upper urinary tract. It is the simultaneous study of pressure, flow, and dynamic x-ray of the upper urinary tract and it keeps same indications than the original design, in spite of the appearance of new dynamic and static imaging techniques (ultrasound, CT scan, MRI, radioisotope studies).

Objective: To review the diagnostic and prognostic importance of pathologic findings in prostate biopsies.

Materials And Results: While the primary goal of the biopsy is to diagnose prostatic adenocarcinoma, once carcinoma is detected, information regarding the type, amount, and grade of cancer forms the cornerstone for contemporary management of the patient and for assessment of the potential for local cure and the risk for distant metastasis.

Conclusions: The novelty of this 2005 update is represented by a detailed morphologic and immunohistochemical description of prostatic adenocarcinoma features in biopsies.

Objectives: To compare the clinical profile (age, comorbidities, symptom severity, and incidence of acute urinary retention, AUR), the type and duration of medical treatment, and indications for surgery of patients undergoing surgery for benign prostatic hyperplasia (BPH) in 1992 and 2002 at one centre.

Patients And Methods: In this single-centre, retrospective, cross-sectional observational study, the medical history of all patients who had surgery for BPH in the first semester of 1992 (85) and 2002 (70) was reviewed. The preoperative clinical profile was determined by assessing age, main comorbidities, prostatic volume, maximum urinary flow rate and symptom severity.

Objectives: To review the evidence currently available to establish the pathogenic connection between erectile dysfunction (ED) and cardiovascular disease (CVD), and the effects this scientific progress has introduced in the classical impotence urology clinic.

Methods: We reviewed the most recent publications about this disease (2000-2004) and the concept of endothelial dysfunction by appropriate MEDLINE searches, with specific selection of reviews and clinical practice guidelines.

Results: The fact that ED and CVD share risk factors is confirmed; the pathogenic unity of both processes having endothelial dysfunction as the underlying problem; anticipation of ED over CVD in time of presentation; notable increase of research about this issue over the last two years; the change of scenario in the impotence urology clinics due to these findings.

Purpose: Permixon is a lipidosterolic extract of Serenoa repens (SR) widely used to treat men with benign prostatic hyperplasia (BPH). We tested the effect of this drug on molecular mechanisms associated with apoptosis, such as the Bax-to-Bcl-2 expression ratio and caspase-3 activity, in prostatic tissue from men with symptomatic BPH treated for 3 months before surgery.

Materials And Methods: An open, multicenter pilot study of 2 parallel groups of patients with BPH was done.
