Objectives: To evaluate the effect of implanted S-nitrosoglutathione (GSNO) coating polypropylene mesh in foreign-body response of rats.
Methods: Thirty female rats underwent to subcutaneous implant of five polypropylene (PP) fragments: uncoated PP (control); PP polyvinylalcohol (PVA) coated and PP PVA + GSNO (1, 10 and 70 mMol) coated. After euthanasia (4 and 30 days), eight slides were prepared from each animal: hematoxylin-eosin (inflammatory response); unstained (birefringence collagen evaluation); TUNEL technique (apoptosis); and five for immunohistochemical processing: CD-31 (angiogenesis), IL-1 and TNF-α (proinflammatory cytokynes), iNOS (NO synthesis) and MMP-2 (collagen metabolism).
Objectives: To describe acute and sub acute aspects of histological and immunohistochemical response to PP implant in a rat subcutaneous model based on objective methods.
Materials And Methods: Thirty rats had a PP mesh subcutaneously implanted and the same dissection on the other side of abdomen but without mesh (sham). The animals were euthanized after 4 and 30 days.
The use of meshes has become the first option for the treatment of soft tissue disorders as hernias and stress urinary incontinence and widely used in vaginal prolapse's treatment. However, complications related to mesh issues cannot be neglected. Various strategies have been used to improve tissue integration of prosthetic meshes and reduce related complications.

Introduction And Hypothesis: Collagen has been proposed to be a useful biomaterial, but previous attempts to combine meshes with a collagen membrane have failed. The objective was to verify the effect of high-purified collagen gel coating in the immune-inflammatory response, host collagen metabolism, and angiogenesis around polypropylene mesh.
Methods: In 20 female Wistar rats were implanted, at one side of the abdominal wall, a monofilament polypropylene mesh (PP), and, on the other side, a mesh coated with a new highly purified collagen gel (PPC).
Objective: To determine whether preoperative cystometry and a pressure flow study (PFS) are necessary in patients with end-stage renal disease from nonurologic causes who will undergo renal transplantation.
Methods: From April 2009 to June 2010, 30 patients scheduled to undergo renal transplantation were prospectively evaluated with cystometry and PFS. The evaluation was performed immediately before and 6 months after renal transplantation.
Clinical complications of implantable polypropylene (PP) meshes used to repair urinary incontinence and vaginal prolapse may be associated with their low surface energy and consequent poor tissue integration. For improving tissue integration, we impregnated monofilament PP meshes with physically crosslinked poly(vinyl alcohol) (PVA), resulting in PVA deposits tightly attached inside the knot spaces of the PP knit. While preserving the mesh porosity, the PVA deposits acted as an array of hydrophilic regions leading to a great increase in the overall mesh wettability, reflected by a contact angle decrease from 111 to ca.

Methods: Thirty-five female patients with multiple sclerosis were randomized into two groups: a treatment group (n = 18) and a sham group (n = 17). The evaluation included use of the Overactive Bladder Questionnaire, Medical Outcomes Study Short Form 36, International Consultation on Incontinence Questionnaire Short Form, and Qualiveen questionnaire.
Introduction And Hypothesis: Stress urinary incontinence (SUI) can occur simultaneously with anterior vaginal prolapse (AVP) in up to 30% of patients. We studied a monoprosthesis that combines prepubic and transobturator arms for simultaneous treatment of AVP and SUI.
Methods: One hundred four women with AVP underwent surgical treatment using a monoprosthesis (NAZCA TC).
Background And Purpose: With the widespread early detection programs for prostate cancer, there has been a downward stage migration and a marked decrease in the percentage of men with seminal vesicle invasion (SVI) compared with previous data. We evaluated clinicopathologic findings that are associated with SVI to select patients for potential seminal vesicle-sparing surgery.
Patients And Methods: We reviewed our radical prostatectomy database from 1997 to 2006 to evaluate the incidence and clinical correlates of SVI.
Introduction: The aim of this study was to analyze the results of vesicostomy in children as a protector of the upper urinary tract and assess the adjustments taken by the caregivers.
Materials And Methods: Twenty-one children who had undergone vesicostomy with the Blocksom technique were evaluated. Their mean age was 3.
Objectives: Voiding dysfunction and urinary retention were frequent complications of sling. More recently synthetic supplies such as polypropylene mesh have been included in the armamentarium for sub urethral support.
Methods: A prospective non randomized study was conducted.
Purpose: To evaluate in a prospective study the impact of the "three-drug therapy" (antimuscarinic, alpha-blocker and tricyclic antidepressants) on the treatment of refractory detrusor overactivity (DO).
Methods: Data from 27 consented patients with refractory DO were available for study. They were asked to complete a daily urinary chart and underwent urodynamic evaluation (UD) before and 60 days after treatment.
Objectives. Using a urethral device at the fossa navicularis, bladder pressure during voiding can be estimated by a minimal invasive technique. This study purposes a new diagnostic index for patients with lower urinary tract symptoms (LUTSs).

We evaluated the effectiveness of the sentinel lymph node biopsy using lymphoscintigraphy in patients with penile cancer and at least one negative inguinal region.
Materials And Methods: In 18 patients, biopsy of the sentinel lymph node from the 32 negative inguinal regions and modified radical lymphadenectomy in these regions regardless of the biopsy results was performed.
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 were prospectively evaluated through conventional urodynamics and classified according to the bladder outlet obstruction index (BOOI).
Introduction: Adrenal carcinomas are rare and are associated with a very poor prognosis. The incidence is estimated to be 1 in 1.7 million which represents 0.
