Genital-Sparing Cystectomy versus Standard Urethral-Sparing Cystectomy Followed with Orthotopic Neobladder in Women with Bladder Cancer: Incidence and Causes of Hypercontinence with an Ultrastructure Study of Urethral Smooth Muscles.

Background: Bladder cancer in women is an indication for radical cystectomy (RC) when the tumour is confined muscle-invasive bladder cancer (MIBC) of T2 N0M0, or high risk progressive non-muscle invasive bladder cancer (NMIBC). Radical cystectomy is either genital-sparing cystectomy (GSC) or standard urethra-sparing cystectomy (USC) that is followed with orthotopic ileal neobladder (ONB). Post-operative chronic retention "Hypercontinence" had been reported in different series following URS or GSC and ONB.

The ex vivo and in vivo Characteristics of New DrillCutTM Prostate Morcellator after Holmium Laser Enucleation of the Prostate: A Pilot Study.

Introduction: The DrillCutTM morcellator is marketed for its fast and highly efficient removal of prostatic tissue and a higher level of patient safety. However, a paucity of publications has looked into its actual efficacy and safety. The aim of our study was to evaluate its ex vivo and in vivo efficiency and to compare its results with other devices presented in the literature.

Expression of ERG Protein and TMRPSS2-ERG Fusion in Prostatic Carcinoma in Egyptian Patients.

Aim: Prostate cancer (PCa) is the second most common cancers in men worldwide. Its incidence can be influenced by several risk factors including genetic susceptibility. Therefore the search for the expression of a certain gene (ERG) and its rearrangement could give us clues for proper identification of PCa.

Randomized, double-blind, placebo-controlled trial to compare solifenacin versus trospium chloride in the relief of double-J stent-related symptoms.

Purpose: We aimed to compare the safety and efficacy of solifenacin versus trospium chloride and compare each drug versus placebo regarding the relief of stent-related symptoms following uncomplicated ureteroscopic lithotripsy (URSL).

Methods: In a prospective, randomized, double-blind study, 210 eligible patients who underwent URSL with double-J stent insertion were recruited and randomly assigned to either the first group, receiving solifenacin (10 mg), second group, receiving trospium chloride (60 mg), or the third group, receiving placebo (one tablet). All patients were kept on study medication once daily during the entire 2-week postoperative period.

Value of Computed Tomography for Predicting the Outcome After Percutaneous Nephrolithotomy.

Introduction: Computerized tomography of the urinary tract (CT-UT) has been established as the diagnostic procedure of choice for urinary stones. This study aimed to evaluate its role in predicting the outcome of percutaneous nephrolithotomy (PCNL) in terms of stone free rate and residual fragments.

Method: This prospective cohort study was conducted on 34 patients in the Urology Department of Theodor Bilharz Research Institute from January 2013 to March 2014.

Low-dose bacille Calmette-Guérin for non-muscle-invasive bladder cancer: Results of a prospective study.

Objective: To evaluate the efficacy and safety of low-dose (45 mg) intravesical bacille Calmette-Guérin (BCG) therapy in the treatment of patients with non-muscle-invasive bladder cancer (NMIBC), as intravesical BCG is the most acceptable adjuvant therapy for NMI transitional cell carcinoma of the bladder. However, in the standard regimen, undesirable effects are the main cause of treatment discontinuation.

Patients And Methods: The present study included 37 men with primary NIMBC.

LAPAROSCOPIC MANAGEMENT OF DISTAL URETERIC STONE IN BILHARZIAL URETER: RESULTS OF A SINGLE CENTER PROSPECTIVE STUDY.

No doubt, Bilharzial ureters are complicated by distal stricture due to precipitation of Bilharzial ova in distal ureter. These cases are associated with poorly functioning and grossly hydronephroic kidneys that hinder endoscopic manipulation of the coexistent distal, high burden, long standing impacted stones. Thus, laparoscopic uretrolithotomy was performed in 51 bilharzial patients with distal ureteric stones 4 trocars were used.

Laparoscopic management of distal ureteric stones in a bilharzial ureter: Results of a single-centre prospective study.

Objective: To determine the efficacy and safety of the laparoscopic management of an impacted distal ureteric stone in a bilharzial ureter, as bilharzial ureters are complicated by distal stricture caused by the precipitation of bilharzial ova in the distal ureter. These cases are associated with poorly functioning and grossly hydronephrotic kidneys that hinder the endoscopic manipulation of the coexistent distal high burden of, and long-standing, impacted stones.

Patients And Methods: We used laparoscopic ureterolithotomy, with four trocars, to manage 51 bilharzial patients (33 men and 18 women; mean age 40.

The clinical significance of HER2 protein amplification/expression in urinary bladder lesion.

Objective: To evaluate HER2 oncoprotein expression by both immunohistochemical (IHC) staining and fluorescence in situ hybridisation (FISH) in different benign and malignant bladder lesions, and the effect of bilharzial infestation on this expression.

Patients And Methods: In a prospective controlled study, 72 patients were classified into a control group, and groups with cystitis, urothelial carcinoma, and squamous cell carcinoma (SCC). HER2 was detected using standard IHC staining and FISH in all groups.

Diagnostic and Prognostic Significance of Serum and Tissue Galectin 3 Expression in Patients with Carcinoma of the Bladder.

Background: Galectins are group of proteins found in the cytoplasm, nucleus, cell surface and extracellular matrix. Galectin 3 (Gal-3) displays pathological expression in a variety of processes such as tumorigenesis.

Patients And Method: 70 patients classified into the control group, cystitis group, transitional cell carcinoma group, and squamous cell carcinoma group were enrolled in this study which aimed to detect the serum level and the intensity of tissue expression of Gal-3.

Single-step renal dilatation in percutaneous nephrolithotomy: A prospective randomised study.

Objective: To perform an economical single-step renal dilatation (RD) during percutaneous nephrolithotomy (PCNL), using directly a 30-F Amplatz dilator over the central Alken dilator, in a trial to reduce the operative duration and radiation exposure during RD while avoiding an exchange of dilators that might increase the risk of blood loss.

Patients And Methods: In a prospective randomised study including 49 patients divided into two groups, the first had RD before PCNL using the standard metallic telescopic dilators (Alken), and the second had RD using the 30-F Amplatz dilator over the central Alken dilator. The operative duration, with X-ray exposure, was calculated.
