OBJECTIVE: Urolithiasis is a common urological problem, and its incidence has been increasing worldwide, including in Japan. Relationships between stone etiology and rise in ambient temperature have been reported, but it remains unclear how age and gender affect these relationships. MATERIALS AND METHODS: A retrospective examination was conducted of the medical archives of 1005 patients (aged ≥15 years) with acute renal colic diagnosed with urolithiasis upon image examination who consecutively visited emergency departments in three hospitals...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

We present the case of a 37-year-old lady who presented with severe colicky left sided flank pain associated with vomiting, chills and rigors. A non-contrast Computed Tomography of the Kidney Ureter and Bladder was performed which showed a 2-3 mm stone in the pelvic part of the left ureter. Following 2 days of conservative treatment she was still complaining of increasingly severe pain. A contrast computed tomography of the abdomen was performed which was suggestive of a perforation of the left collecting system...

OBJECTIVES: To evaluate the in vitro effect of tamsulosin and nifedipine on the contractility of pregnant rat ureters and to perform quantitative analysis of the pharmacological effects. Medical expulsive therapy (MET) is commonly used to treat urolithiasis. However, this treatment is seldom used in pregnant women since no studies support this practice. METHODS: This was an in vitro study on animal tissue derived from pregnant Sprague-Dawley rats. A total of 124 ureteral segments were mounted in an organ bath system and contractile response to methacholine (MCh) was assessed...

OBJECTIVES: Although previous studies have indicated that stone heterogeneity can affect shock wave lithotripsy outcomes, there is no established measurement of stone heterogeneity on computed tomography imagery. We investigated whether variation coefficient of stone density can predict shock wave success. MATERIALS AND METHODS: We conducted a retrospective review of 245 patients with urinary calculi who had undergone shock wave lithotripsy. We compared the predictive powers of treatment success between variation coefficient of stone density and other parameters associated with computed tomography attenuation...

Understanding urolith trends and risk factors is important for understanding urolithiasis, which is a common problem in dogs. This study evaluated 75 674 canine cystolith submissions to the Canadian Veterinary Urolith Centre between 1998 and 2014. Struvite and calcium oxalate uroliths comprised 80.8% of all uroliths, with calcium oxalate outnumbering struvite. There were significant increases in the proportions of calcium oxalate, mixed and cystine uroliths, and significant decreases in struvite, urate, silica, and calcium phosphate carbonate over the study period...

PURPOSE OF REVIEW: Flexible ureteroscopy has been widely developed in the last decade been nowadays one of the first line treatment options for urolithiasis and conservative management for upper tract urothelial tumors. Even though some unfavorable features of the reusable flexible scopes can limit the surgical procedure such as their availability, lack of sterilization or costly repairs. Disposable scopes have been developed with the intention of improving such problems. RECENT FINDINGS: To our knowledge, seven devices have been developed...

Urinary stone disease, particularly calcium oxalate, is common in both humans and cats. Calcifying nanoparticles (CNP) are spherical nanocrystallite material, and are composed of proteins (fetuin, albumin) and inorganic minerals. CNP are suggested to play a role in a wide array of pathologic mineralization syndromes including urolithiasis. We documented the development of a clinically relevant protocol to assess urinary CNP in 9 healthy cats consuming the same diet in a controlled environment using Nanoparticle Tracking Analysis (NTA®)...

Keratinizing desquamative squamous metaplasia (KDSM) in the renal pelvis is a rare condition with unclear malignant potential. Recent reports suggest it is likely benign and favor endoscopic treatment approaches. Medical record review was completed on two cases at our center to obtain history, physical examination, radiographic findings, and management. A literature review was completed to identify all published cases of KDSM. Both patients at our center suffered recurrent urolithiasis, hypothesized to be secondary to KDSM...

BACKGROUND: Potassium citrate (K-Cit) is one of the therapeutic solutions broadly used in patients with urolithiasis. However, recent studies have shown that it is not so effective. Therefore, the goal of our study was to evaluate the effect of a combination of K-Cit - MgCl2 oral supplements, on urinary stone size. MATERIALS AND METHODS: This study was performed on 70 asymptomatic urolithiasis cases. The supplements included K-Cit and magnesium chloride (MgCl2), purchased from (Merck Company, Germany)...

Kidney diseases in human immunodeficiency virus (HIV)-infected patients are often misdiagnosed. Despite reductions in morbidity and mortality owing to widespread use of highly effective combination antiretroviral therapy (cART), acute kidney injury (AKI) and chronic kidney disease (CKD) are still more common in these patients than in the general population, and are associated with poor health outcomes. HIV-associated nephropathy and HIV immune complex kidney diseases are the more recognizable HIV-related kidney diseases...

We present a case of a 41-year-old woman with medical history significant for urolithiasis presenting to our hospital for psychiatric evaluation due to worsening depression and suicidal ideations for the past 2 weeks. Initial laboratory results show hypercalcaemia of 13.5 mg/mL that led to consulting internal medicine. On further questioning, the patient admitted to cosmetic silicone injections in her buttocks which were causing calcium deposition under her skin, leading to disfigurement of the sacrum and lumbar regions...

Bioactive compounds phytic acid (IP6) and pyrophosphate (PPi) are minor components of walnuts with the ability of being inhibitors of urolithiasis, among others. Since simultaneous analysis of IP6 and PPi have known drawbacks, a new method to determine their content in walnuts has been developed with emphasis on their extraction from walnuts by microwave-assisted extraction (MAE). Acid content of extracting solvent, extraction time and temperature were optimized. After extraction, compounds were purified by selective adsorption/desorption on an anion exchange solid phase extraction and analyzed by inductive coupled plasma/mass spectrometry...

In recent years, intense efforts have been made to clarify the pathogenesis of urolithiasis, which affects more than 10% of the population of developed countries. Currently, a number of studies have assumed a key role in the pathogenesis of oxalate urolithiasis, which is the most common one that belongs to the active forms of oxygen generated in the kidney, as a result of the activation of free radical oxidation that occurs in the interaction of calcium oxalate crystals with renal tubular epithelial cells. In the current work, oxidant and antioxidant status were assessed in the blood of patients with complicated urolithiasis pre - and post surgery...

INTRODUCTION: The efficiency of holmium laser lithotripsy for urolithiasis depends upon several factors, including laser pulse energy and frequency and stone composition and retropulsion. This study investigates the complex interplay between these factors and quantifies lithotripsy efficiency using different laser settings in a benchtop kidney and ureter model. MATERIALS AND METHODS: In vitro caliceal and ex vivo porcine ureteral models were constructed. Calcium oxalate monohydrate stones were fragmented using a 200-μm laser fiber...

The role of the strength of family history of stones (FHS), i.e., degree of relatives with the disease, on the course of calcium urolithiasis (CU) is not fully understood, particularly in young patients where genetic background has the greatest influence on disease expression. Thus, with a retrospective cross-sectional design, we examined baseline clinical parameters and urinary chemistries of 369 subjects (196 M) with CU and 96 controls (41 M) aged between 15 and 25 at the time of the first visit at our stone clinic...
