Gross hematuria is common in autosomal dominant polycystic kidney disease (ADPKD). It is an alarming symptom and may be the first manifestation of ADPKD. Cyst hemorrhage is a frequent cause of hematuria in ADPKD while other differential diagnoses include cyst infection, urinary tract infection, renal stones and an underlying malignancy. Knowledge of the precipitating factors and clinical presentation of these conditions will help practicing internists in performing an appropriate evaluation and management of these entities and their complications, as well as executing timely referrals to subspecialists when indicated...

Renal disease is a well-recognized manifestation of cystic fibrosis (CF) and people with CF are at increased risk of nephrolithiasis. Lithotripsy is the preferred treatment but has occasionally been associated with pulmonary complications. Here we report the case of a person with CF who developed a pneumothorax soon after lithotripsy and discuss the potential mechanism of injury. We hope this case highlights some of the additional considerations clinicians should take into account when managing patients with advanced pulmonary disease in CF...

Purpose: Ureteroscopic lithotripsy (URS) is gaining popularity for the management of ureteral stones and even renal stones, with high efficacy and minimal invasiveness. Although this procedure is known to be safe and to have a low complication rate, febrile urinary tract infection (UTI) after URS is not rare. Therefore, we aimed to analyze the risk factors and causative pathogens of febrile UTI after URS. Materials and Methods: Between January 2013 and June 2015, 304 patients underwent URS for ureteral or renal stones...

Urolithiasis is a common, highly recurrent disease with increasing prevalence worldwide. The association between vitamin D and calcium stones has often been investigated on the basis of the role of vitamin D in calcium homeostasis. Currently, there is no consensus on the management of vitamin D deficiency in patients with renal calculi, because of controversies about the relationship between vitamin D and calcium stones. However, the vitamin D deficiency is shown to be highly prevalent among kidney stone formers, and some studies found a higher prevalence in stone formers compared with non-stone formers...

Uretero-pelvic junction obstruction (UPJO) is a common condition, often presenting in adulthood in developing countries. These cases can pose significant problems owing to late presentation and complications such as infection, stones, and impaired renal function. We present the case of a 28-year-old female who presented to us with recurrent symptoms and impaired drainage following a failed open pyeloplasty and robot-assisted ureterocalycostomy for right UPJO. She was managed by robot-assisted boari flap calycovesicostomy, an innovation which helped in salvaging her kidney; ensuring good drainage in the involved kidney...

Urolithiasis is a common urological problem. In most cases, this multifactorial pathology develops due to the combination of inherited low-penetrance gene variants and environment factors such as urinary tract infections and unbalanced diet. However, some cases are monogenic. These hereditary forms of urolithiasis manifest in childhood, and are characterized by multiple, bilateral and recurrent kidney stones and progress to chronic renal failure relatively early. Due to widening acceptance of exome and gene panel sequencing, substantially larger percentages of urolithiasis cases are now attributed to hereditary causes, up to 20% among patients of 18 years old or younger...

Introduction: Imaging is a vital cog in the wheel of diagnosis and management of patients suspected with renal and ureteric calculi, and it is imperative to choose the appropriate investigation that is accurate as well as safe for the patient. At present, computed tomography (CT) is the gold standard for a patient suspected to have stone disease. However, CT scan is associated with the hazards of radiation and high cost. Ultrasonography (US) is cheap and also devoid of any radiation hazard to the patient...

Xanthogranulomatous pyelonephritis (XGP) is an unusual form of chronic pyelonephritis in which the renal parenchyma is destroyed and replaced by lipid-laden foamy macrophages. It usually affects middle-aged women with a history of recurrent urinary tract infection, diabetes, or kidney stones. The inflammatory process is usually diffuse and can extend beyond the kidney. The rare focal forms may simulate primary renal tumours. The preoperative imaging diagnosis may be difficult. We reported five cases of XGP, The findings of ours were recorded including kidney size, shape, contour, the echogenecity of the renal parenchyma, the internal echoes of the dilate collecting system, the presence of perinephric fluid accumulation and obstruction...

About 12% of world population is affected by different forms of urolithiasis of which the recurrence rate in female is 47-60% and in male is 70-80%. Standard therapeutic agents (allopurinol, citrate, cystone and thiazide diuretics) are used to prevent and treat urolithiasis but these are not universally-effective due to common kidney stone relapse and other side effects. Surgical treatment causes long-term renal damage, hypertension and stone recurrence. Polyphenols, the plant-derived bioactive molecules, have showed protection against cancers, cardiovascular diseases, diabetes, osteoporosis and neurodegenerative diseases, among a number of other ailments...
