Study population The study population comprised adult patients with a solitary, radiopaque distal ureteral calculus below the bony pelvis, 15mm or less in diameter. Exclusion criteria were multiple ureteral calculi, solitary kidney, renal insufficiency, ipsilateral ureteral stricture, plan for simultaneous treatment of ipsilateral renal or contra lateral renal or ureteral calculi, active urinar...

BACKGROUND Kidney stones in patients with autosomal dominant polycystic kidney disease are common, regarded as the consequence of the combination of anatomic abnormality and metabolic risk factors. However, complete staghorn calculus is rare in polycystic kidney disease and predicts a gloomy prognosis of kidney. For general population, recent data showed metabolic factors were the dominant caus...

Treatment of renal calculi is highly dependent on the chemical composition of the stone in question, which is difficult to determine using standard imaging techniques. The objective of this study is to evaluate the potential of scatter-sensitive X-ray dark-field radiography to differentiate between the most common types of kidney stones in clinical practice. Here, we examine the absorption-to-s...

Background. We present our centres successful endourological methodology of ex vivo ureteroscopy (EVFUS) in the management of these kidneys prior to renal transplantation. Patient and Methods. A retrospective analysis was performed of all living donors (n = 157) identified to have asymptomatic incidental renal calculi from January 2004 until December 2008. The incidence of asymptomatic renal ca...

Unilateral renal aplasia (URA), which belongs to congenital solitary functioning kidney (CSFK), may lead to renal failure in patient’s later life. URA is often associated with other malformations, among which urological anomalies are the most common ones. Herein, we present a case of a 52-year-old man with the left URA and aplastic ureter with ipsilateral seminal vesicle opening to (AUISVO). Th...

Urinary tract infection, hydronephrosis, calculi, and tumor of the renal pelvis are knownas complications and multiple congenital anomalies can occur together with a horseshoe kidney (1). However, the occurrence of membranousnephropathy (MN) in a horseshoe kidney has been only reported in a few case reports (2, 3). Furthermore, horseshoe kidney and focal sclerosing glomerulonephritis were seen ...

Kidney stone is a common problem in population and had medical or surgical treatment. Surgery treatment had many technique, but now, Percutaneous Nephrolithotomy (PCNL) is a standard surgery care of renal calculi. In recent years, surgeons defined modification methods of PCNL such as tubeless PCNL and totally tubeless PCNL. These modified methods were associated with less complication, reduced ...

INTRODUCTION The aim of this study was to evaluate percutaneous nephrolithotomy (PCNL) in the patients with solitary kidneys. MATERIALS AND METHODS Between 1995 and 2005, we had 11 patients with a solitary kidney and kidney calculi who underwent PCNL at our center. Tubeless and standard PCNLs were performed in 3 and 7 patients. In 1 patient, we could not achieve access to the system due to th...

PURPOSE Residual fragments following ureteroscopy for calculi may contribute to stone growth, symptoms or additional interventions. We reviewed our experience with ureteroscopy for calculus disease to define the incidence and establish factors predictive of residual fragments. MATERIALS AND METHODS Records associated with 667 consecutive ureteroscopic lithotripsy procedures for upper urinary ...
