[Epidemiology of urinary lithiasis in Spain: New scenarios.]
Authors: Carrasco Valiente J, Gómez Gómez E, Requena Tapia MJ Abstract 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 ...

How do stones form? Is unification of theories on stone formation possible?
Authors: Bird VY, Khan SR Abstract There are two basic pathways for formation of calcium based kidney stones. Most idiopathic calcium oxalate (CaOx) stones are formed in association with sub-epithelial plaques of calcium phosphate (CaP), known as Randall's plaques, on renal papillary surfaces. Crystal formation and retention within the terminal collecting ducts, the ducts of Bellini, leading to the formation of Randall's plugs, is the other pathway. Both pathways require supersaturation leading to crystallization, regulated by various crystallization modulators produced in response to changing urinary conditions. H...

[Urinary lithiasis as a systemic disease.]
Authors: Leanez Jiménez M, Candau Vargas-Zúñiga F, Reina Ruiz C Abstract 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...

[Etiopathogenic factors of the different types of urinary litiasis.]
Authors: Arrabal-Martín M, Cano-García MC, Arrabal-Polo MÁ, Domínguez-Amillo A, Canales-Casco N, de la Torre-Trillo J, Cózar-Olmo JM Abstract 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 di...

[Metabolic study. How to make it accessible, useful and generalized.]
Authors: Lancina Martín JA Abstract 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 ...

[May renal lithiasis be really prevented? New trends and therapeutic tools.]
Authors: Grases F, Costa-Bauzá A, Prieto RM Abstract 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. For this reason, the a...

Being diet one of the risk factors for urolithiasis, and having it evolved in conjunction with lifestyle over the last decades, such changes could explain the increase in lithiasis case-load. In this article, we analyze how the exercise of the urologist has been regarding the preventive role of diet in the lithiasis patient, what are the scientific evidences on the relationship of diet and lithiasis,...

Technique, minimal requirements and fragmentation strategies in RIRS.
Authors: Cansino Alcaide JR, Portilla Eastmond A Abstract 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.

[Current results of RIRS and comparison with PCNL.]
CONCLUSIONS: RIRS is a safe and effective technique, with a similar success rate to PCNL if one assumes the possibility of retreatment in stones>2cm. Its low complication rate, fast postoperative recovery and short hospital stay make this technique a therapeutic alternative to PCNL in this type of patients. Compared with percutaneous techniques less invasive than classical 24 to 30 Ch. accesses (miniperc or microperc), RIRS offers a higher stone free rate. If we also consider that RIRS is associated with shorter hospital stay and lower bleeding risk, even without significant differences in the global complication rate w...

Due to the versatility and independence involved in having the ability to perform the renal puncture in the operative room, as well as its influence in the results of PCNL, it must be the urologist himself who performs this basic step of percutaneous surgery.

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. Nevertheless, it presents a series of technical limitations...

Minimally invasive PCNL-MIP.
Authors: Zanetti SP, Boeri L, Gallioli A, Talso M, Montanari E Abstract Miniaturized percutaneous nephrolithotomy (mini-PCNL) has increased in popularity in recent years and is now widely used to overcome the therapeutic gap between conventional PCNL and less-invasive procedures such as shock wave lithotripsy (SWL) or flexible ureterorenoscopy (URS) for the treatment of renal stones. However, despite its minimally invasive nature, the superiority in terms of safety, as well as the similar efficacy of mini-PCNL compared to conventional procedures, is still under debate. The aim of this chapter is to present one of t...

Ureteral stent encrustation. Pathophysiology.
Authors: Kram W, Buchholz N, Hakenberg OW Abstract Ureteral stents are the most commonly used urological implants. They are used for temporary as well as for long-term ureteral stenting. Amongst others, complications of ureteral stenting are encrustation and cellular adherence which, in turn, promotes urinary tract infection and can induce impaired healing in case of ureteral damage. Biofilm formation on urological implants leads to the protection of persisting bacteria from local defense mechanisms, thereby rendering persistent urinary tract infections more common. It seems clear that antibiotics cannot penetrate ...
