PURPOSE To investigate the effect of performing shockwave lithotripsy (SWL) before retrograde intrarenal surgery (RIRS) on the treatment outcomes of patients with nephrolithiasis. MATERIALS AND METHODS The data of 189 patients with renal stones who underwent RIRS from July 2007 to July 2014 was reviewed retrospectively. Patients with stones larger than 1.5 cm were recommended to undergo SWL b...

PURPOSE The objective of this study was to evaluate the efficacy of tamsulosin on stone clearance after extracorporeal shock wave lithotripsy (ESWL) in patients with a single proximal ureteral stone. MATERIALS AND METHODS This prospective randomized controlled trial was performed on 88 patients with a single proximal ureteral stone. After consenting with a doctor, the patients were allocated ...

A range of algebras between lattices and Boolean algebras generalise the notion of a complement. We develop a hierarchy of these pseudo-complemented algebras that includes Stone algebras. Independently of this theory we study filters based on partial orders. Both theories are combined to prove Chen and Grätzer’s construction theorem for Stone algebras. The latter involves extensive reasoning ab...

BACKGROUND A wide variety of complications due to the extrauterine migration of intrauterine contraceptive devices have been reported in the literature. Here we describe the case of a large bladder stone formed around a migrated Copper T380A device that was neglected and detected 15 years after insertion. CASE PRESENTATION A 48-year-old Sri Lankan woman underwent a workup for lower urinary tr...

PURPOSE Urolithiasis develops more frequently in patients with a family history (FHx). However, little is known about risk factors in stone formers with a FHx. The aim of this study was to examine the clinico-metabolic characteristics of urinary stone formers according to FHx. MATERIALS AND METHODS A database of 1,068 stone formers who underwent a complete metabolic evaluation was reviewed. T...

A study was undertaken to analyses the heritability, correlation and path co-efficient for growth and fruit characters in twenty ber (Ziziphus mauritiana Lam) genotypes grown at Fruit Research Farm under Horticulture Research Centre, BARI during January to June 2006. The highest range of variation was recorded in fruit weight (6.63-44.72 g), followed by yield per plant (14.88 64.99 kg), stone w...

INTRODUCTION The aim of this study was to identify predictive factors of success following a single-session of shock wave lithotripsy (SWL) at 3 weeks of follow-up in our center. MATERIAL AND METHODS The medical records of 116 patients with solitary urinary calculi who underwent single-session SWL in our department between October 2007 and August 2009 were reviewed. All preoperative unenhance...

Out of all methods for ground improvement, stone column became more popular these days due to its simple construction and economic consideration. Installation of stone column especially in loose fine graded soil causes increasing in load bearing capacity and settlement reduction. Encased granular stone columns (EGCs) are commonly subjected to vertical load. However, they may also be subjected t...

Dens invaginatus (dens in dente) is a rare malformation with a widely varied morphology. An unusual presentation of a type III dens invaginatus affecting a conical shaped permanent lateral incisor in an 8-year-old female patient is reported. The presence of a pulp stone and a periapical radiolucency further added onto the complexity of the case. The etiology, pathophysiology, association with o...
