Fifty-four patients with infected renal lithiasis underwent complete metabolic evaluation searching for underlying factors contributing to stone formation including urine analysis and culture. Metabolic abnormalities were significantly more present in patients with mixed infected stones (struvite+/-apatite and calcium oxalate) than in patients with pure infected stones (struvite+/-carbonate apatite): hypercalciuria in 40%, hyperoxaluria in 34% and hyperuricosuria in 28% (p < 0.05). Urinary excretion of citrate was low in both groups without statistically significant difference (238+/-117 mg/24 h vs 214+/-104 mg/24/h, t = 0...

The urolithiasis, with a high incidence nowadays, including formations caused by gallstone of uric acid, has a high correlation to our lifestyles and dietary habits. Through a clinic case, it is intended to review the main nursing actions that may occur with this pathology. To achieve this, the data collected on physical examination and nursing assessment on the model of Virginia Henderson, while the full care plan is developed. The results show the need to establish a standardized healthy education intervention, related to a low-pruine healthy diet for people that suffer this disease...

OBJECTIVE: To present a predictive tool of success of ESWL adapted to our environment. METHODS: We performed a retrospective, descriptive and analytical study of patients with renal and upper ureteral stones whom underwent ESWL with DUET MAGNA lithotripter between January 2014 and March 2015. We included 114 patients in whom demographics and CT scan characteristics were studied. Multivariate analysis by logistic regression was performed to establish independent predictors of success in ESWL...

PURPOSE: The aim of this study was to evaluate the efficacy and tolerance of renal stone fragmentation by flexible ureterorenoscopy (URS), compared to percutaneous nephrolithotomy (PCNL). MATERIAL AND METHODS: Patients treated between 1998 and 2010 by URS and PCNL for intrarenal stone were reviewed. Patients' and stones' characteristics were analyzed. The preoperative parameters were reported as well as the procedure's efficiency and its complications. Success was defined by the absence of residual lithiasis visualized on renal imaging at 6 months of follow-up...

Ureteral stents are one of the most commonly used urologic devices with the purpose of establishing and maintaining ureteral patency. They are also associated with a number of complications including infection, migration, stent-related symptoms, and encrustation, leading to lithiasis. Prolonged stent dwell time is associated with a greater degree of these complications. We present the case of a 36-year-old man who presented with a severely encrusted ureteral stent that had been placed 12.5 years prior for an obstructive left-sided ureteral stone and was lost to follow-up...

BACKGROUND: Although endoscopic combined intrarenal surgery (ECIRS) is well established as primary approach to complex lithiasis, no evidences are still available on its use in salvage context. CASE PRESENTATION: A male patient, of 55 years of age, underwent many unsuccessful surgical procedures to treat large and multiple right kidney stones, including percutaneous nephrolithotomy (PCNL). The latter was complicated by severe postoperative hemorrhage, managed with super-selective renal artery embolization (SRAE)...

INTRODUCTION: In special situations such as malrotated or ectopic kidneys and UPJ stenosis treatment of renal lithiasis can be challenging. In these rare cases laparoscopy can be indicated. OBJECTIVE: Describe the Laparoscopic-assisted rigid nephroscopy performed via transpyelic approach and report the feasibility. PATIENTS AND METHODS: We present two cases of caliceal lithiasis. The first is a patient that ESWL and previous percutaneous lithotripsy have failed, with pelvic kidney where laparoscopic dissection of renal pelvis was carried out followed by nephroscopy utilizing the 30 Fr rigid nephroscope to remove the calculus...

BACKGROUND: "Watchful waiting" or "active surveillance" is an alternative approach in the medical management of certain diseases. Most often considered appropriate as an approach to treatment for low-risk prostate cancer, it is also found in the literature in breast cancer surveillance, urinary lithiasis, lymphocytic leukemia, depression and small renal tumors. OBJECTIVES: This systematic review sought to:Identify and synthesize the best available international evidence on the experience of adults who choose watchful waiting or active surveillance as an approach to medical treatment...

OBJECTIVE: To analyze results (stone-free rate [SFR]) and complications after flexible ureterorenoscopy (f-URS) for renal or lumbar ureteral lithiasis in patients with a previous ureteral stenting (US). PATIENTS AND METHODS: We conducted a single-center retrospective study, including all f-URS procedures achieved in our department, between January 2004 and December 2010, for renal or lumbar ureteral urinary lithiasis. In total, 497 procedures were performed: 316 procedures in patients with a ureteral stent placed before the surgery for renal colic, sepsis, or renal failure (group 1) and 181 procedures in patients without US (group 2)...

INTRODUCTION: Calcium oxalate stones are the most common urolithiasis. Changes in dietary habits, socio-economic and health status of populations explain its progression. The aim of our study was to determine metabolic factors leading to lithiasis and clarify its causes. PATIENTS AND METHODS: This is a retrospective study of 100 patients with calcium oxalate stones identified by morpho-constitutional study, collected in our department over a period of 5 years (2008-2013)...

A 74-year-old man presented with right flank pain and a palpable mass in the left flank. Blood pressure was normal. Contrastenhanced computed tomography (CT) showed a 17 × 16 × 12 cm retroperitoneal mass over the left kidney, solid and heterogeneous. There were also 3 retro aortic lymph nodes and bilateral renal lithiasis. Twenty four-hour urinary metanephrines and normetanephrines were normal. The patient underwent a resection of the mass with left adrenalectomy by a lumbar incision. Histological findings revealed an adrenal oncocytic neoplasm (AON) with uncertain malignant potential...

In the last decade, cross-sectional and multiple cohort studies have associated total fluid intake or water intake with the risk for chronic kidney disease (CKD) and even the risk of developing hyperglycemia. Urine biomarkers have also been linked to the risk of CKD and lithiasis, and these biomarkers respond quickly to variations in fluid intake. High circulating copeptin levels, a surrogate marker of arginine vasopressin, have been associated with metabolic syndrome, renal dysfunction and increased risk for diabetes mellitus, cardiovascular disease and death...

INTRODUCTION: Shock wave lithotripsy (SWL) is the treatment of choice for most cases of renal lithiasis in children. Some cases, however, are refractory to SWL and may be associated with anatomic and metabolic changes or a large stone burden. In these circumstances, mini-percutaneous nephrolithotomy (mini-PCNL) is an option. OBJECTIVE: The aim was to assess the safety and efficacy of high-power holmium YAG (Ho:YAG) laser in mini-PCNL for staghorn calculi. PATIENTS AND METHODS: The clinical records relating to 35 mini-PCNLs (Table) performed between January 2008 and December 2012 in 33 patients (27 boys and 6 girls; mean age 7 years, range 2-18 years) were retrospectively reviewed...

Cysts are frequently found in chronic kidney disease (CKD) and they have a different prognostic significance depending on the clinical context. Simple solitary parenchymal cysts and peripelvic cysts are very common and they have no clinical significance. At US, simple cyst appears as a round anechoic pouch with regular and thin profiles. On the other hand, hereditary polycystic disease is a frequent cause of CKD in children and adults. Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are the best known cystic hereditary diseases...

Chronic tubulointerstitial diseases are a common final pathway toward chronic renal failure regardless the primary damage (glomerular, vascular or directly the tubulointerstitium). Chronic tubulointerstitial nephritis (CTN) is characterized by interstitial scarring, fibrosis and tubule atrophy, resulting in progressive chronic kidney disease. Most frequent causes of CTN are drugs, heavy metals, obstructive uropathy, nephrolithiasis, reflux disease, immunologic diseases, neoplasia, ischemia, metabolic diseases, genetics and miscellaneous...
