Congenital anomalies of the kidneys and urinary tracts can result in diminished natal kidney function, possibly through common embryologic pathway disruption or as a result of development taking place in the face of disordered 'post-renal' drainage. Impaired conduit and reservoir function present potential for an ongoing assault leading to further deterioration and progression of chronic kidney disease, a risk that extends to adults with these conditions, even after "correction". The drainage and storage aspects of the urinary system that can impact kidney function are reviewed with attention to correctable or manageable problems including: Bladder dysfunction wherein the low pressure storage of urine is compromised requiring the kidney to work against a pressure gradient, the classic post renal failure problem...

Biliary and urinary obstructions can be managed endoscopically or cystoscopically, surgically or by percutansous intervention or drainage. If the obtructed system is infected, emergent decompression is needed. Early recognition and treatment is paramount in both conditions. Acute cholangitis can present many different ways, from mild symptoms to fulminant sepsis. It is usually a result of ascending bacterial colonization and biliary obstruction resulting in bacterial overgrowth. Therefore, those patients with recent biliary instrumentation or previous biliary modification are at higher risk...

Introduction: Cirrhosis of the liver and diabetes mellitus are two chronic illnesses with significant impact on the quality of life. Studies from different part of the world have shown the combination to be associated with higher incidence of complications of cirrhosis and reduced survival. However, data on the impact of pre-cirrhotic and post-cirrhotic diabetes on cirrhosis is minimal. Aim: The aim of the study was to determine the complications of cirrhosis patients with and without co-existent DM and to compare the relation between cirrhosis patients with antecedent DM and hepatogenous DM...

BACKGROUND: Kidney stone disease is common in industrialized countries. Recently, it has attracted growing attention, because of its significant association with adverse renal outcomes, including end stage renal disease. Calcium-containing kidney stones are frequent with high recurrence rates. While hypercalciuria is a well-known risk factor, restricted intake of animal protein and sodium, combined with normal dietary calcium, has been shown to be more effective in stone prevention compared with a low-calcium diet...

Congenital ureteropelvic junction obstruction (UPJO) is the most common cause of upper urinary tract obstruction in children. It is generally diagnosed in the routine work-up during antenatal period and is characterized by spontaneous recovery. It can be associated with urolithiasis; hence further investigation should be carried out. We report the case of a 15-year-old boy, who is known to have right UPJO, presented with right renal colic and discovered to have bilateral kidney stones. Further studies showed primary hyperparathyroidism and genetic analysis revealed a CDC73 mutation (initially HRPT2)...

PURPOSE: To help rein in surgical spending, there is growing interest in the application of payment bundles to common outpatient procedures like ureteroscopy (URS) and shockwave lithotripsy (SWL). However, before urologists can move to such a payment system, they need to know where their episode costs are concentrated. MATERIALS AND METHODS: Using claims data from the Michigan Value Collaborative, we identified patients who underwent URS or SWL at hospitals in Michigan (2012 to 2015)...

<b>Introduction</b>: Cystinuria is a genetic disorder marked by elevated urinary cystine excretion and recurrent cystine nephrolithiasis. Interestingly, despite seemingly similar contralateral renal anatomy, a subset of cystinuric patients consistently form stones in only one kidney. The aim of this study is to evaluate clinical outcomes in unilateral versus bilateral cystine stone formers. <b>Methods</b>: We performed a retrospective case-control study of cystinuric patients evaluated and treated at the University of California, San Francisco between 1994 and 2015 and categorized patients as either unilateral or bilateral stone formers...

Treatment for stone disease has evolved drastically during the past 3-4 decades. Ureteroscopy, percutaneous nephrolithotomy along with SWL, provides the means to treat practically all urinary tract stones with minimal invasion to the patients. However, for complex stone case scenarios where open surgery is being considered, a less invasive and better tolerated option such as laparoscopy (robot assisted or not) can be performed. The present manuscript reviews role of laparoscopic and robotic surgery in treating urinary tract stones...

BACKGROUND: It remains controversial as to whether active stone removal should be performed in patients with poor performance status because of their short life expectancy and perioperative risks. Our objectives were to evaluate treatment outcomes of active stone removal in patients with poor performance status and to compare life prognosis with those managed conservatively. METHODS: We retrospectively reviewed 74 patients with Eastern Cooperative Oncology Group performance status 3 or 4 treated for upper urinary tract calculi at our four hospitals between January 2009 and March 2016...

Primary hyperoxaluria type I (PH1) is a rare disease caused by the deficit of liver alanine-glyoxylate aminotransferase (AGT). AGT prevents oxalate formation by converting peroxisomal glyoxylate to glycine. When the enzyme is deficient, progressive calcium oxalate stones deposit first in the urinary tract and then at the systemic level. Pyridoxal 5'-phosphate (PLP), the AGT coenzyme, exerts a chaperone role by promoting dimerization, as demonstrated by studies at protein and cellular level. Thus, variants showing a destabilized dimeric structure should, in principle, be responsive to vitamin B6, a precursor of PLP...

Preoperative nomograms offer systematic and quantitative methods to assess patient- and stone-related characteristics and their impact on successful treatment and potential risk of complication. Discrepancies in the correlation of perioperative variables to patient outcomes have led to the individual development, validation, and application of four independent scoring systems for the percutaneous nephrolithotomy: Guy's stone score, S.T.O.N.E. nephrolithometry, Clinical Research Office of the Endourology Society nomogram, and Seoul National University Renal Stone Complexity...
