Abstract Objective: Extracorporeal shock wave lithotripsy for treatment of ureteric calculi is difficult due to reduced visibility of the stone. Intravenous contrast medium (IV-CM)administration may overcome this problem by indirect depicting the localization of the stone . The aim of the study was to compare the clinical outcome after ESWL in two representative groups of patients with either radiolucent or ... Read more

Abstract We evaluated the use of Tubularized incised plate on primary and recurrent hypospadius repair. MATERIALS AND METHODS We retrospectively reviewed the medical records of all boys who underwent hypospadias repair at Sohag University Hospital during a recent 2-year period. The level of the hypospadias defect, technique of repair, age at surgery and complications were recorded. RESULTS A total of ... Read more

PURPOSE: To report the short term results of Snodgrass Tubularized incised plate (TIP) Urethroplasty in distal and mid penile Hypospadias repair. MATERIALS AND METHODS: forty-three patients with the mean (range) age of 7.3 (2-10) years having distal penile (n = 30) and mid penile Hypospadias (n = 13), who underwent TIP Urethroplasty were included in this study. Patients were followed ... Read more

ABSTRACT The success of various types of flaps procedures for primary hypospadias was assessed taking the location of meatus and the degree of chordee as the basis. Totally 200 patients with primary hypospadias were operated: 80 by perimeatal flap and tube repair 70by preputial flap and 50 by onlay falp. The rates of success in cases, perimeatal flap and preputial ... Read more

The ultimate role of various alternative methods of performing TURP remains to be determined. Electrovaporization is a modified electrosurgical modality that is quickly gaining popularity. However, long term efficacy and safety data have yet to mature and determine whether TUEVP will be a durable long-term modality in the treatment of lower urinary tract symptoms. To compare efficacy, safety, and durability ... Read more

Abstract: The expression of certain growth factors in the epidermal growth factor (EGF) family is altered in response to renal injury. Recent studies have demonstrated that heparin binding EGF-like growth factor (HB-EGF) expression may be cytoprotective in response to apoptotic signals. The purpose of this study was to investigate the potential role of HB-EGF in the upper urinary tract following ... Read more

ABSTRACT OBJECTIVE: To compare the efficacy, safety and durability of transurethral electrovaporization of the prostate (TUVP) with standard transurethral resection (TURP) in a prospective randomized trial. PATIENTS AND METHODS: The study included 110 consecutive men with symptomatic benign prostatic hyperplasia (BPH) admitted for surgery who were randomized to TUVP or TURP. The variables evaluated included the duration of surgery, catheterization ... Read more

PURPOSE: To evaluate contrast agent-enhanced harmonic ultrasonographic (US) imaging and Doppler hemodynamics during acute urinary obstruction. MATERIALS AND METHODS: In 12 piglets, the distal ureter was obstructed for 60 minutes, followed by intravenous injection of furosemide. In six piglets, ureteral pressure was further elevated to mean arterial pressure, and in six other piglets ureteral obstruction was released. Contrast-enhanced harmonic imaging ... Read more

This study is a trial to conform a rational approach to the appropriate management of renal trauma, as the rate of renal trauma is increasing due to the increase in the human activities. It included 32 patients presented at the causality unit of Assiut University Hospital over a Period of 1.5 year, from January 1992 to June 1993. Blunt trauma ... Read more
