The data of 60 patients admitted to Mansoura Urology and Nephrology Center with penile fractures and treated by immediate surgical repair were reviewed with respect to their presentation, investigations, operative and post-operative details. Forty-nine patients were followed up regarding penile curvatures, plaques and erectile function. Patients reporting(More)
PURPOSE We evaluated the urodynamic features of enuretic and continent patients with an orthotopic neobladder. MATERIALS AND METHODS Included in our study were 100 men with an orthotopic hemi-Kock or W neobladder and a minimum followup of 1 year. Of the patients 50 were completely continent day and night, and 50 had enuresis without evidence of an(More)
PURPOSE We evaluated whether an artificial neural network (ANN) can improve the prediction of stone-free status after extracorporeal shock wave lithotripsy (ESWL) (Dornier Medical Systems, Inc., Marietta, Georgia) for ureteral stones compared to a logistic regression (LR) model. MATERIALS AND METHODS Between February 1989 and December 1998, 984 patients(More)
OBJECTIVE To evaluate the efficacy of two drugs: the anticholinergic agent oxybutynin (Ditropan) and the calcium channel blocker verapamil (Isoptin) in the management of nocturnal enuresis in patients with orthotopic ileal reservoirs. MATERIAL AND METHODS The study population comprised 20 male enuretic patients who had undergone radical cystoprostatectomy(More)
PURPOSE We retrospectively reviewed our experience with the artificial urinary sphincter for post-prostatectomy incontinence, comparing the outcome of those patients who did and did not receive previous radiation therapy. MATERIALS AND METHODS A total of 86 patients with post-prostatectomy incontinence treated with implantation of artificial urinary(More)
PURPOSE A significant percentage of patients with post-prostatectomy incontinence have been reported to void by Valsalva's maneuver, which is our observation as well. We determine the mechanism of voiding in patients with post-prostatectomy incontinence and correlate this to demographic data, urodynamic parameters and outcome after artificial urinary(More)
OBJECTIVE To report our experience with the use of 95% ethanol as sclerotherapy for symptomatic simple renal cysts. PATIENTS AND METHODS Sixty patients with 64 symptomatic simple renal cysts were treated by ultrasonography (US)-guided percutaneous aspiration and injection of 95% ethanol (31 men and 29 women, mean age 46 years, SD 22). The main(More)
OBJECTIVE To assess the nature, distribution and expression pattern of CD75, a neuraminidase-sensitive lymphocyte cell surface differentiation antigen, in calcium oxalate (CaOx) stone disease, as cell-surface sialic acid might be involved CaOx crystal binding, and lectin-binding assays suggest that sialic acid in the alpha2,6 position is upregulated in(More)
PURPOSE We studied the possible causes of chronic retention after radical cystectomy and orthotopic bladder substitution in women. MATERIALS AND METHODS Between January 1995 and January 2001, 136 women with a mean age plus or minus standard deviation of 52 +/- 8 years underwent standard radical cystectomy and orthotopic substitution for organ confined(More)
OBJECTIVE To evaluate the effect of patient and tumour characteristics on the disease-free survival after radical cystectomy for infiltrating bladder cancer, and to use these to help in constructing a meaningful prognostic index. METHODS The disease-free survival was initially evaluated in 1026 patients (the reference series, 1969-1990). A multivariate(More)
