The Panel is aware of the geographical variations in healthcare provision. Management of bladder stones has previously not been addressed in these guidelines; however, as of the edition, bladder stones are dealt with in a new, separate, guideline authored by the same guideline urolithiasis BPH. It must be emphasised that clinical guidelines present the best evidence available urolithiasis BPH the experts but following guideline recommendations will not necessarily result urolithiasis BPH the best outcome.

Guidelines are not mandates and do not purport to be a legal standard of care. The EAU Urolithiasis Guidelines Panel consists of an international group of clinicians with particular expertise in this area.

A quick reference document Pocket guidelines is available, both in print and as an app for iOS and Android devices. These are abridged versions, which may require consultation urolithiasis BPH with the full text versions. Also a number of scientific publications are available [ ]. This document presents a limited update of the version.

The literature for the entire document has been assessed and updated, wherever relevant see Methods section below. Forconclusions and recommendations have been rephrased and added to throughout the current document, including the sections on high-risk stone formers, anti-coagulation and paediatric urolithiasis.

Updated summaries of evidence and recommendations include the following:. Offer opiates hydromorphine, pentazocine or tramadol as a second choice. Careful imaging control of localisation of stone contributes to outcome of treatment. Careful control of pain during treatment is necessary to limit pain-induced movements and excessive respiratory excursions. Antibiotic prophylaxis urolithiasis BPH recommended in the case of internal stent placement, infected stones or bacteriuria.

Consider the stone composition before deciding on the method of removal, based on patient history, former urolithiasis BPH analysis of the patient or Hounsfield unit HU on unenhanced computed tomography CT.

Offer laparoscopic or open surgical stone removal in rare cases in which shock wave lithotripsy SWLretrograde or antegrade ureteroscopy and percutaneous nephrolithotomy fail, or are unlikely to be successful. Shock wave lithotripsy for small calyceal stones is an option with minimal risk of complication, but localisation of the stone can be challenging and SFRs are poor.

Offer children with single ureteral stones less than 10 mm shock wave lithotripsy SWL if localisation is possible as first line option. Ureteroscopy is a feasible alternative for ureteral stones not amenable to SWL. For the Urolithiasis BPH Guidelines, new and urolithiasis BPH evidence has been identified, collated urolithiasis BPH appraised through a structured assessment of the literature.

A broad and comprehensive scoping exercise covering all areas of the guideline was performed. Urolithiasis BPH search was limited to studies representing high levels of evidence only i. The search was restricted to articles published between 1 st July and 1 st May A total of unique records were identified, and screened for relevance.

Based on the reference lists of selected papers from the overall scope search and Panel expertise, additional relevant papers not identified in the search have been included in the Paediatric Urolithiasis session. A total of 25 new papers have been added to the Urolithiasis Guidelines publication. For each recommendation within the guidelines there is an accompanying online strength rating form, the basis of which is a modified GRADE methodology [ 45 ]. Each strength-rating form addresses a number of key elements, namely:.

These key elements are the basis which panels use to define urolithiasis BPH strength rating of each recommendation. The strength of each urolithiasis BPH is determined by the balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence including certainty of estimatesand nature and variability of patient values and preferences.

The strength rating forms will urolithiasis BPH available urolithiasis BPH. A list of associations endorsing the EAU Guidelines can also be viewed online at the above address.

The Urolithiasis Guidelines were subjected to urolithiasis BPH prior to publication. For their text update the Urolithiasis Guidelines Panel aim to perform extended literature searches in urolithiasis BPH parts of the Guideline where evidence is currently poor. Potential examples include: MET in children and robot-assisted laparoscopic stone treatment. Further goals for future iterations of the Urolithiasis Guidelines will be determined over the course of Stone incidence depends on geographical, climatic, ethnic, dietary and genetic factors.

The recurrence risk is basically determined by the disease or disorder causing the stone formation. There is emerging evidence linking nephrolithiasis to the risk of chronic kidney disease urolithiasis BPH 12 urolithiasis BPH. Stones can be stratified into those caused by: infection, or non-infectious urolithiasis BPH, genetic defects [ 13 ]; or adverse drug effects drug stones Table 3.

MgHPO 4. The risk status of stone formers is of particular interest because it defines the probability of recurrence or regrowth, and is imperative for pharmacological treatment. Stone type and disease severity determine low- urolithiasis BPH high risk of recurrence Table 3.

Urinary stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence [ 10]. Stones can be classified according to anatomical position: upper, urolithiasis BPH or lower calyx; renal pelvis; urolithiasis BPH, middle or distal ureter; and urinary bladder.

Treatment of bladder stones is not discussed in these urolithiasis BPH. Stones can be classified according to plain X-ray appearance [kidney-ureter-bladder KUB radiography] Table urolithiasis BPH. Non-contrast-enhanced computed tomography NCCT can be used to classify stones according to density, inner urolithiasis BPH and composition, which can affect treatment decisions Section 3.

Stratification of stones according to aetiology, composition and risk of recurrence is addressed in Section 3. The most appropriate imaging modality will be determined by the clinical situation, which will differ depending on if a ureteral or a renal stone is suspected.

Standard evaluation includes a detailed medical history and physical examination. Patients with ureteral stones usually present with loin pain, vomiting, and sometimes fever, but may also be asymptomatic [ 35 ]. Immediate evaluation is indicated in patients with solitary kidney, fever or when there is doubt regarding a diagnosis of renal colic.

Ultrasound US should be used as the primary diagnostic imaging tool, although pain relief, or any other emergency measures, should not be delayed by imaging assessments.

Ultrasound is safe no risk of radiationreproducible and inexpensive. It can identify stones located in the calices, pelvis, and pyeloureteric and vesico-ureteral junctions US with filled bladderas well as in patients with upper urinary tract UUT dilatation. Kidney-ureter-bladder radiography should not be performed if NCCT is considered [ 39 ]. However, Urolithiasis BPH is helpful in differentiating between radiolucent and radiopaque stones and should be used for comparison during follow-up.

Non-contrast-enhanced computed tomography CT has become the standard for diagnosing acute flank pain, and has replaced intravenous urography IVU.

Non-contrast-enhanced CT can determine stone diameter and density. When stones are absent, the cause of abdominal pain should be identified. Non-contrast-enhanced CT can detect uric acid and xanthine stones, which are radiolucent on plain films, but not indinavir stones [ 41 ]. Non-contrast-enhanced CT can determine stone density, inner structure of the stone, skin-to-stone distance and surrounding anatomy; all of which affect selection of treatment modality [ 34urolithiasis BPH.

The advantage of non-contrast imaging must be balanced against loss of information on renal function and urinary collecting system anatomy, as well as higher radiation dose [ ]. Radiation risk can be reduced by low-dose CT, which may, however, be difficult to introduce in standard clinical practice [ ].

A MA of prospective studies [ 51 ] has shown that low-dose CT diagnosed urolithiasis with a pooled sensitivity of Dual-energy CT can differentiate uric acid containing stones from calcium-containing stones [ 53 ]. Intravenous urography can provide information about renal function, the anatomy of the collecting system and the level of an obstruction, while CT urolithiasis BPH for rapid 3D data acquisition including information on stone size and density, skin-to-stone distance and surrounding anatomy, but at the cost of increased radiation exposure.

Urolithiasis BPH and ultra-low-dose protocols seem to yield comparable urolithiasis BPH as standard-dose protocols with the exception of detection of very small stones or stones in obese patients [ 515254 ].

A small randomised study showed that in supine urolithiasis BPH antegrade ureteroscopy Urolithiasis BPHpre-operative planning using CT, compared urolithiasis BPH IVU, resulted in easier access and shorter operating times [ 55 ]. In case stone removal is planned and the renal collecting system needs to be assessed, a contrast study should be performed [ 56 ].

Non-contrast-enhanced CT is used to confirm stone diagnosis in patients with urolithiasis BPH flank pain, as it is superior to Urolithiasis BPH. Enhanced CT enables 3D reconstruction of the collecting system, as well as measurement of stone density urolithiasis BPH skin-to-stone distance. With fever or solitary kidney, and urolithiasis BPH diagnosis is doubtful, immediate imaging is indicated.

Following initial ultrasound assessment, use non-contrast-enhanced computed tomography to confirm stone diagnosis in patients with acute flank pain. Perform a contrast study if stone removal is planned and the anatomy of the renal collecting system needs to be assessed.

Each emergency patient with urolithiasis needs a succinct biochemical work-up of urine and blood besides imaging. At this point, no distinction is made between high- and low-risk patients for stone formation.

Biochemical work-up is similar for all stone patients.
