INTRODUCTION We intended to evaluate the feasibility and effectiveness of the simultaneous rigid and flexible ureteroscopic treatment of symptomatic ureteral and ipsilateral small simultaneous calyceal stones. Outcomes of combined therapy were compared with monotherapy alone. MATERIAL AND METHODS In this retrospective study, group 1 consisted of 45 patients with middle or lower ureteral and i...

Background: In weak clay soil, a proper ground improvement technique using stone column can be limited by the absence of sufficient lateral confining pressure. Stone columns should strengthened to provide minimum required Objective: The aim this study is find out significant composite compared conventional comparing bearing capacity enhancement and treated soil stiffness for both models. Compos...

PURPOSE Percutaneous nephrolithotomy effectively treats large volume renal calculi but relies on postoperative imaging to judge success. We evaluated the effectiveness of maximizing intraoperative imaging through combined high resolution fluoroscopy and flexible nephroscopy. MATERIALS AND METHODS Percutaneous nephrolithotomy was performed cooperatively with a radiologist in an interventional ...

The behaviour of beam-column joint plays an important role in the response of a steel moment resisting framed structure especially under seismic excitation. Semi rigid connections like bolted joints, allow better energy dissipation and provide good response under lateral loads. In this paper the ductility and energy dissipation characteristics of semi rigid bolted connections using double web a...
