Renal lithiasis is known for its high incidence and prevalence, but mainly for its morbidity and recurrence. Despite a good indication and appropriate surgical treatment, the essential problem, the origin of the formation of the stones, generally persists and it is not uncommon that patients suffer multiple treatments and discomfort secondary to ancillary measures normally used to prevent complications. It is widely known, for consistency, that a prophylactic treatment with general or, in a smaller group of patients, specific measures are appropriate to diminish recurrences...

Miniaturization in percutaneous surgery has seen its zenith in microperc. Technological advances have enabled us to treat renal lithiasis through a 4.8 Ch. caliper percutaneous access. According to published literature, the technique is reproducible and when applied to small and medium size renal lithiasis has a high success rate keepin a low complication rate. Its main advantage is the absence of tract dilatation, diminishing the bleeding risk inherent to percutaneous access, postoperative pain and hospital stay...

OBJECTIVES: The objective of this article is to show the current situation regarding two surgical techniques for the treatment of renal lithiasis, RIRS (Retrograde intrarenal surgery) and PCNL (Percutaneous nephrolithotomy), specially concerning the larger size stones. We perform a literature review on the topic and add the experience with both techniques at our center. Besides, we also analyze the role of RIRS in comparison with the percutaneous techniques in smaller size lithiasis. METHODS: We review the results obtained in the literature and our experience...

Flexible ureteroscopy is a highly resolving surgery which is able to solve most renal lithiasis of any Urology Department, with very low economic impact. It is a technique that has helped to continue treatment when SWL couldn't, and also has reduced the number of percutaneous renal surgeries that we currently perform. In this paper, we try review three important features of the operation: Technique, minimal requirements that we need to perform this surgery in a Urology Department, and the different possibilities to treat the lithiasis with holmium laser...

OBJECTIVE: The contribution of therapeutic ureteroscopy done by Perez Castro in 1980 varied the management algorithm for ureteral lithiasis worldwide. The techniques of Retrograde Ureteroscopy and transrenal antegrade ureteroscopy led to the abandonment of open surgery for the treatment of ureteral lithiasis. Only Shock wave lithotripsy has maintained similar success rates in selected cases. METHODS: Descriptive analysis of the semirigid and flexible ureteroscopy techniques performed in our department over the last 10 years giving detail on the technique and safety tips to increase the efficacy and efficiency of ureteroscopy...

Renal calculi are generally formed as a result of the combination of certain factors, some related to urine composition (concentration of lithogenic substances, deficiency of crystallization inhibitors, presence of heterogeneous nucleants) and others with renal morphology and anatomy (urinary tract stasis, low urodynamic efficiency cavities, morpho-anatomic deformations, renal papillary tissue lesions). In fact, the composition, macrostructure and microstructure of the calculus will clearly depend on the factors that have induced it...

Risk factors should be evaluated in all patients with urinary lithiasis. The kind of evaluation, simplified or extended, depends on stone composition and, in patients with calcium lithiasis, on the clinical presentation. These studies are done in an outpatient regimen, are easy to perform and accessible for most laboratories. Patients with uric acid, infectious and cystine stones only require a selective more abbreviated evaluation. In calcium lithiasis we perform an extended metabolic evaluation in recurrent patients and also in singleepisode patients when they have high recurrence risk...

In this review, we analyze the etiopathogenic principles of urinary lithiasis formation. In the kidney, calcifications that may cause renal lithiasis are produced as a consequence of processes that injury the urothelium at the papilla and Bellini's ducts. With the improvement of imaging techniques, mainly micro CT scan, it is possible to detect them and we may be able to anticipate to the formation of lithiasis. As we well know, there are different factors that influence the formation of the calculi depending on their composition...

Urinary lithiasis is a prevalent disorder of uncertain origin which provokes health problems through potential harm to the urinary system, renal parenchyma or the body as a whole, with a frequent trend to relapse. Historically urinary calculi have been studied and treated as an isolated disease but nowadays we know more about their connection with other pathological entities. In a small percentage of patients, diseases like primary hyperparathyroidism, tubular renal acidosis, inflammatory bowel disease or bariatric surgery have a fairly well studied physiopathological link with kidney stones...

Renal lithiasis is one of the most common disorders in modern society, constituting an important health problem that associates a great economic burden. The nature of stone disease varies according to age and sex, being also influenced by dietary and lifestyle factors, and climatic variations among others. In spite of the advances made in the management of this pathology, it continues being a disease with a high recurrence rate. In recent years, several studies have pointed out that its prevalence is rising especially in developed countries...

BACKGROUND: Ureteric colic is the most common symptom of lithiasis. It is caused by the presence of stones accumulated in the renal papillae. These stones often migrate down the ureter, causing a ureteric colic, characterized by a severe pain in the lumbar region. The aim of this study was to compare the use of ketorolac and nifedipine vs. ketorolac and tamsulosin for the medical treatment of pain caused by stones in the lower ureter. METHODS: Longitudinal study of 150 patients of 21-years or older with stones in the lower third of the ureter...

BACKGROUND: In France, the coordinated healthcare circuit means that patients should be referred to specialists, for example nephrologists, by another physician. However, there are no recommendations concerning the reasons justifying the referral to a nephrologist. The main purpose of our study is to describe the motif of first consultations in nephrology in the health area 5 of Brittany. METHODS: We retrospectively collected medical reports of first consultations by 17 nephrologists in the 4 centers of the study area, during the year 2014...

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...

REVIEW

Urolithiasis in the context of renal transplant is a quite rare event that requires keeping a higher index of suspicion and vigilance. Donors with incidentally discovered asymptomatic renal stones "donor gifted lithiasis" are potentially considered for donation should they are not recurrent stone formers and in the absence of active biochemical disorders. Stone clearance from the donors can be done before donation using shock wave lithotripsy and/or flexible ureteroscopy. Ex vivo ureteroscopy at time of transplant is equally feasible and safe...

BACKGROUND: Acute pancreatitis (AP) following KT is a rare and often fatal complication of the early post-transplant period. Common causative factors for AP are rare after KT; anti-rejection drugs as CyA, prednisone and MMF have been implicated, although evidence is not strong and we found no reports on possible causative role for mTOR inhibitors. CASE PRESENTATION: A 55-year-old Caucasian man with end-stage renal disease due to idiopathic membrano-prolipherative glomerulonephritis underwent single kidney transplantation (KT) from cadaveric donor...
