The aim of this study was to determine the clinical characteristics and diagnosis of severe, acute urolithiasis in infants and toddlers, caused by melamine contamination in infant formula milk. The clinical data of 28 patients were collected and analyzed. Among the 28 patients, 17 patients received indwelling ureteral stents by cystoscopy (60.71%) and 5 patients received open surgery to extract...
Duplex kidney (DK) is the most common congenital abnormality of the urinary tract, with an incidence of around 0.82%1,2. Basis of duplex kidney formation by embryology is explained as development of two ureteral buds separately from a single mesonephric duct gives rise to a duplex kidney with complete ureteral duplication. On the other hand, bifurcation of a single ureteral bud proximal to the ...
Ureteral duplication is a common congenital anomaly of the urinary system observed in 0.8% of autopsy series [1]. However, bifid ureter with a blind branch is a rare condition. It is three times more prevalent in women than men and is observed twice as often on the right side as on the left side [2]. It does not generally give any clinical symptoms. However, in the literature, symptomatic cases...
Blind-ending ureteral duplication is a rare congenital anomaly of the urinary system, with only a few cases reported in the literature.1 The anomaly is diagnosed three times more frequently in women than in men, and twice as often on the right side. It has also been reported in twins and sisters.2 The majority of cases are diagnosed in the third or fourth decade of life. Many of these blind seg...
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 ...
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...
