Inflammation may activate stem cells via prostaglandin E2 (PGE2) production mediated by cyclooxygenase-2 (COX-2) expression. We performed an immunohistochemical analysis of the expression of stemness markers (Oct3/4 and CD44v6) and COX-2 in urinary bladder tissues obtained from cystitis and cancer patients with and without Schistosoma haematobium(More)
INTRODUCTION Aim of this study was to assess the safety and efficacy of injection of autologous muscle-derived cells into the urinary sphincter for treatment of postprostatectomy urinary incontinence in men and to characterize the injected cells prior to transplantation. METHODS 222 male patients with stress urinary incontinence and sphincter damage after(More)
BACKGROUND Uretero-ileal anastomotic stricture (UIAS) is a urological complication after ileal neobladder, the initial management being endourological intervention. If this fails or stricture recurs, surgical intervention will be indicated. DESIGN AND PARTICIPANTS From 1994 to 2013, 129 patients were treated for UIAS after unsuccessful endourological(More)
INTRODUCTION This is an observational retrospective study utilising long term patient follow-up for 15 years to determine the survival and quality of life in women (age range 20-54 years) after having been treated for carcinoma of the bladder by radical cystectomy with preservation of genital organs. MATERIAL AND METHODS The study included 13 female(More)
Infection with urinary schistosomiasis and its severity are oncogenic factors for developing carcinoma of the bladder, whether it is urothelial carcinoma (UC) of a transitional cell type (TCC) or non-urothelial of squamous cell carcinoma (SCC). In UC it is not defined whether it is schistosomal or not. This led to controversial results in expression of(More)
Objectives. Many techniques were described for ureteroileal anastomosis in orthotopic bladder substitution, ranging from nonrefluxing to refluxing techniques, all aiming at preservation of the upper tract. We describe our technique of dipping the ureter into the ileal pouch, which is simple and had no complications. Patients and Methods. Our technique(More)
