We describe a case in which a Weck Hem-o-lok clip (Teleflex, Research Triangle Park, USA) migrated into the collecting system and acted as a nidus for stone formation in a patient after robot-assisted partial nephrectomy. The patient presented 2 years postoperatively with left-sided renal colic. Abdominal computed tomography scan showed a 10 millimeter renal calculus in the left middle pole. Af...

BACKGROUND Stphylococcus cohnii is an organism of coagulase negative species which is considered as normal flora. However, it has been isolated from urinary tract infections and surgical prostheses but its relation with staghorn stones has not been reported, yet. CASE PRESENTATION A 50-years-old woman presented with left renal staghorn stone in June 2014. She had bilateral staghorn stones 7 y...

Two patients with renal pelvic stone in a horseshoe kidney who underwent a percutaneous nephrolithotripsy (PNL) are presented.

INTRODUCTION The aim of this study was to investigate the value of renal resistive index (RI) for the assessment of renal colic and to determine whether it is predictive of renal stone disease. METHODS A total of 70 participants were included in the research study. Group 1 comprised 43 patients with acute unilateral ureteral obstruction due to a stone disease (G1), while Group 2 consisted of ...

INTRODUCTION AND OBJECTIVES Ectopic pelvic kidneys with renal stones are challenging to treat. We report our experience in managing a case of ectopic pelvic kidney with a pelvic stone by robotic pyelolithotomy after failure of flexible ureteroscopy. MATERIALS AND METHODS A 46-year old male with 2 months history of vague lower abdominal pain was found to have on Computed Tomography scan a left...

BACKGROUND This study was carried out to determine whether or not there is a significant relationship between the radiologic anatomy of the lower calyx, as seen on preoperative intravenous urography (IVU), and the outcome of stone clearance after extracorporeal shockwave lithotripsy (ESWL) for lower renal calyceal stones. METHODS Between June 1998 and April 2007, 112 patients with a solitary ...
