BACKGROUND Although some trials assessed the efficacy and safety of the α-blocker in facilitating renal and ureteral stones expulsion after extracorporeal shock wave lithotripsy (ESWL), the role of the α-blocker in facilitating upper urinary calculi expulsion after ESWL remain controversial. AIMS To determine the efficacy and safety of the α-blocker in facilitating renal and ureteral stones e...
Introduction: Flexible ureteroscopy (fURS) is an endoscopic procedure for the minimally invasive treatment of ureteral and renal calculi. Due to improvements in technique and ureteroscopic instrumentation over the past two decades, complications associated with URS are infrequent. However, in the event of an unexpected device malfunction or failure, the operating surgeon must employ prompt, res...
Introduction: Our aim was to compare two types of lithotripter including holmium: YAG laser and pneumatic one in transurethral ureterolithotripsy (TUL) for the management of ureteral calculi ≥1 cm. Methods: 112 patients with ureteral calculi more than 1 cm were selected in randomized order for pneumatic or holmium: YAG laser transurethral ureterolithotripsy (56 patients in each group). Ultrason...
BACKGROUND Patients presenting in the emergency room with flank pain suggestive of acute ureteric colic may have alternative underlying conditions mimicking ureteric stones. An early diagnosis and appropriate treatment for other causes of flank pain is important. The majority of centers around the world are increasingly using un-enhanced helical CT (UHCT) for evaluation of ureteric colic. This ...
PURPOSE To present our experience with emergency ureteroscopic lithotripsy (URSL) for ureteral calculi associated with acute kidney injury (AKI). MATERIALS AND METHODS We retrospectively evaluated the 61 patients consisted of 90 ureteral units (UU), who underwent URSL. The cause of anuria was bilateral calculus obstructions in 29 cases, and unilateral calculus obstruction with, absent, nephre...
Low dose (<3 mSv) noncontrast CT (NCCT) is the imaging study of choice for accurate evaluation of patients with acute onset of flank pain and suspicion of stone disease (sensitivity 97%, specificity 95%). NCCT can reliably characterize the location and size of an offending ureteral calculus, identify complications, and diagnose alternative etiologies of abdominal pain such as appendicitis. By c...
Crossed renal ectopia is a rare congenital anomaly in which both kidneys are situated on one side and fused together in 85%-90% of cases. The management of urinary calculi in patients with crossed renal ectopia continues to pose challenges to urologists because the aberrant anatomy may make access and clearance of the calculi more difficult to accomplish. Here, we report a case of inferior cros...
Received November 2009 Accepted July 2010 INTRODUCTION Since 1980, the extracorporeal shockwave lithotripsy (SWL) has become the gold standard option for treatment of renal and ureteral calculi. But SWL is not without complication and has its own contraindications. Of absolute contraindication for SWL is bleeding tendency. Here, we report a case with bleeding diathesis who underwent SWL without...
A 33-year-old male with an ileal conduit was referred to our department for the treatment of left renal calculi. After inserting a ureteral access sheath, a ureteroscopy-assisted retrograde nephrostomy was made. Percutaneous nephrolithotomy was successfully achieved using this nephrostomy.
