OBJECTIVES: Stability of concentrations of urinary stone-related metabolites was analyzed from samples of recurrent urinary stone formers to assess necessity and effectiveness of urine acidification during collection and storage. METHODS: First-morning urine was collected from 20 adult calcium-stone forming patients at Tomas Bata Hospital in the Czech Republic. Urine samples were analyzed for calcium, magnesium, inorganic phosphate, uric acid, sodium, potassium, chloride, citrate, oxalate, and urine particles. The single-voided specimens were collected without acidification, after which they were divided into three groups for storage: samples without acidification ("NON"), acidification before storage ("PRE"), or acidification after storage ("POST"). The analyses were conducted on the day of arrival (day 0, "baseline"), or after storage for 2 or 7 days at room temperature. The maximum permissible difference (MPD) was defined as ±20 % from the baseline. RESULTS: The urine concentrations of all stone-related metabolites remained within the 20 % MPD limits in NON and POST samples after 2 days, except for calcium in NON sample of one patient, and oxalate of three patients and citrate of one patient in POST samples. In PRE samples, stability failed in urine samples for oxalate of three patients, and for uric acid of four patients after 2 days. Failures in stability often correlated with high baseline concentrations of those metabolites in urine. CONCLUSIONS: Detailed procedures are needed to collect urine specimens for analysis of urinary stone-related metabolites, considering both patient safety and stability of those metabolites. We recommend specific preservation steps.

Referrals to emergency services are frequently made for acute appendicitis and renal colic. This conundrum of patients with acute appendicitis and right ureteral stones frequently presents itself to emergency physicians. The hematological parameters of patients suffering from acute appendicitis and right ureteral stones were compared in this study. From May 2022 to April 2023 the patients who applied to emergency department were reviewed retrospectively. Of these patients, age, sex, complete blood test results including white blood cell, procalcitonin and C-reactive protein were recorded. The platelet to lymphocyte ratio and the neutrophil to lymphocyte ratio were calculated by dividing the platelet count by the lymphocyte, and the neutrophil count by the lymphocyte count, respectively. We used the receiver operating characteristic curves to assess the diagnostic efficacy of hematological markers. There were 106 patients in the study. The mean age of the patients was 43.83 ± 15.82 years. The significant difference was found for age, white blood cell, neutrophil, lymphocyte, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio and monocyte between groups. The white blood cell and neutrophil to lymphocyte ratio have the biggest area than the other parameters in the receiver operating characteristic curves. Patients with acute appendicitis have a high level of neutrophil to lymphocyte ratio, platelet to lymphocyte ratio than ureteral stones. Further studies are needed to define the diagnostic efficacy of hematological markers for acute appendicitis and ureteral stones.

Tubulointersticiální onemocnění jsou poměrně častou příčinou akutního a/nebo chronického onemocnění ledvin. Akutní tubulointersticiální nefritida (ATIN) se nejčastěji vyvíjí v důsledku hypersenzitivní reakce na různé léky a infekce, může být součástí autoimunitních, systémových a metabolických onemocnění, vzniká po expozici environmentálním faktorům. Pokud není induktor ATIN rozpoznán, může se ATIN vyvinout do chronické tubulointersticiální nefritidy (CHTIN). CHTIN může být počátečním projevem autoimunitního, systémového, metabolického nebo environmentálního procesu. Odlišení ATIN od jiných příčin akutního poškození ledvin, jako je akutní tubulární nekróza nebo rychle progredující glomerulonefritida může být obtížné, ale je důležité, protože léčba a prognóza jsou často zcela odlišné. Pro diagnózu je důležité pečlivé klinické hodnocení, určitá laboratorní data a různé zobrazovací metody. Většina těchto testů je však málo senzitivní i málo specifická. K přesné diagnostice ATIN a vedení léčby je často nutná biopsie ledvin. Pro chronickou tubulointersticiální nefritidu je biopsie ledviny potřeba méně často, protože dostupné terapie pro tuto jednotku jsou až na výjimky omezené a primárně podpůrné.

Tubulointerstitial diseases are a relatively common cause of acute and/or chronic kidney disease. Acute tubulointerstitial nephritis (ATIN) most often develops as a result of a hypersensitivity reaction to various drugs or infections, it can be part of autoimmune, systemic and metabolic diseases and may arising after exposure to environmental factors. If an ATIN inducer is not recognized, ATIN can develop into chronic tubulointerstitial nephritis (CHTIN). CHTIN may be the initial manifestation of an autoimmune/ systemic, metabolic or environmental process. Distinguishing ATIN from other causes of acute kidney injury, such as acute tubular necrosis or rapidly progressive glomerulonephritis, can be difficult, but is important because treatment and prognosis are often quite different. Careful clinical assessment, certain laboratory data and various imaging methods are important for diagnostic work up. However, most of these tests are not very sensitive or specific. Renal biopsy is often necessary to accurately diagnose ATIN and guide treatment. For chronic tubulointerstitial nephritis, renal biopsy is needed less often because available therapies for this entity are, with exceptions, limited and primarily supportive.

BACKGROUND AND OBJECTIVE: The aim of this review was to define patients who are at high risk of recurrence of urolithiasis, to delineate diagnostic and therapeutic algorithms for each type of stone, and to clarify general guidelines and recommendations for prevention of recurrence. METHODS: A professional research librarian carried out literature searches for all sections of the urolithiasis guidelines, covering the timeframe between 1976 and June 2023. KEY FINDINGS AND LIMITATIONS: For every patient with urolithiasis, an attempt should be made to analyse the stone. Patients should be given general instructions on how to prevent recurrence, including adequate fluid and calcium intake, and low consumption of sodium and protein. Identifying and correcting the causative factors is a cornerstone in preventing the recurrence of urolithiasis. Diagnostic and therapeutic algorithms by stone composition are available. Every patient should undergo baseline metabolic screening, while patients with calcium stones, who are at high risk of relapse and complications, should undergo extensive metabolic screening with two 24-h urine collections and should receive targeted therapy. Patients with uric acid, infection, or cystine stones are at high risk of relapse. All patients at high risk of recurrence should be closely monitored, especially those not complying with therapy in the long term. CONCLUSIONS AND CLINICAL IMPLICATIONS: Metabolic stone evaluation and patient follow-up are highly recommended to prevent urolithiasis recurrence.

Different international associations have proposed their own guidelines on urolithiasis. However, the focus is primarily on an overview of the principles of urolithiasis management rather than step-by-step technical details for the procedure. The International Alliance of Urolithiasis (IAU) is releasing a series of guidelines on the management of urolithiasis. The current guideline on shockwave lithotripsy (SWL) is the third in the IAU guidelines series and provides a clinical framework for urologists and technicians performing SWL. A total of 49 recommendations are summarized and graded, covering the following aspects: indications and contraindications; preoperative patient evaluation; preoperative medication; prestenting; intraoperative analgesia or anesthesia; intraoperative position; stone localization and monitoring; machine and energy settings; intraoperative lithotripsy strategies; auxiliary therapy following SWL; evaluation of stone clearance; complications; and quality of life. The recommendations, tips, and tricks regarding SWL procedures summarized here provide important and necessary guidance for urologists along with technicians performing SWL. PATIENT SUMMARY: For kidney and urinary stones of less than 20 mm in size, shockwave lithotripsy (SWL) is an approach in which the stone is treated with shockwaves applied to the skin, without the need for surgery. Our recommendations on technical aspects of the procedure provide guidance for urologists and technicians performing SWL.

PURPOSE: We sought to determine which treatment between flexible ureteroscopy and shock wave lithotripsy has a better stone-free rate in pediatric patients (<18 years) with renal or proximal ureteric stones (<2 cm). Subanalysis for all outcomes for randomized controlled trials only. MATERIALS AND METHODS: Using PubMed, Web of Science, and the Cochrane database, we identified studies (randomized clinical trials and prospective comparative nonrandomized studies) published until August 2022 reporting surgical outcomes of pediatrics patients undergoing flexible ureteroscopy and shock wave lithotripsy with renal or proximal ureteric stones <2 cm (PROSPERO ID: CRD42022378790). Only randomized controlled trials were considered for meta-analysis. Stone-free rate, operative time, and complications were analyzed. Analysis was performed in R. RESULTS: A total of 6 studies identified, of which 3 were randomized clinical trials and 4 had data on renal stones. A total of 669 patients were analyzed. Mean age ranged from 4.4 to 12.4 years. The shock wave lithotripsy group presented a range of stone-free rate between 21 and 90% while the flexible ureteroscopy group presented a range of stone-free rates between 37% and 97%. Meta-analysis of randomized controlled trials only (n=302) demonstrated significantly higher stone-free rate in flexible ureteroscopy vs shock wave lithotripsy (RR = 1.17, 95% CI: 1.04-1.33, P = 0.01), operative time (mean difference = +16.4 minutes, 95% CI: 7.3-25.5, P < 0.01) and hospital stay (mean difference = +0.25 days, 95% CI: 0.14-0.36, P < 0.001). But no difference in fluoroscopy exposure time (mean difference = -21.0 seconds, 95% CI: -42.6 to 0.56, P = 0.07), Clavien I-II (RR = 1.23, 95% CI: 0.71-2.12, P = 0.45) or Clavien III-V complications (RR = 1.04, 95% CI: 0.32-3.42, P = 0.95). CONCLUSIONS: Flexible ureteroscopy has a significantly higher stone-free rate than shock wave lithotripsy, with no difference in complication rate or fluoroscopy exposure time, and significantly higher operative times and hospital stay. However, the current evidence base for this is weak and further randomized trials are needed.

PURPOSE: The European Association of Urology (EAU) has updated its guidelines on clinical best practice in urolithiasis for 2021. We therefore aimed to present a summary of best clinical practice in surgical intervention for patients with upper tract urolithiasis. MATERIALS AND METHODS: The panel performed a comprehensive literature review of novel data up to May 2021. The guidelines were updated and a strength rating was given for each recommendation, graded using the modified Grading of Recommendations, Assessment, Development, and Evaluations methodology. RESULTS: The choice of surgical intervention depends on stone characteristics, patient anatomy, comorbidities, and choice. For shockwave lithotripsy (SWL), the optimal shock frequency is 1.0-1.5 Hz. For ureteroscopy (URS), a postoperative stent is not needed in uncomplicated cases. Flexible URS is an alternative if percutaneous nephrolithotomy (PCNL) or SWL is contraindicated, even for stones >2 cm. For PCNL, prone and supine approaches are equally safe. For uncomplicated PCNL cases, a nephrostomy tube after PCNL is not necessary. Radiation exposure for endourological procedures should follow the as low as reasonably achievable principles. CONCLUSIONS: This is a summary of the EAU urolithiasis guidelines on best clinical practice in interventional management of urolithiasis. The full guideline is available at https://uroweb.org/guidelines/urolithiasis. PATIENT SUMMARY: The European Association of Urology has produced guidelines on the best management of kidney stones, which are summarised in this paper. Kidney stone disease is a common condition; computed tomography (CT) is increasingly used to diagnose it. The guidelines aim to decrease radiation exposure to patients by minimising the use of x-rays and CT scans. We detail specific advice around the common operations for kidney stones.

CONTEXT: Endourological procedures frequently require fluoroscopic guidance, which results in harmful radiation exposure to patients and staff. One clinician-controlled method for decreasing exposure to ionising radiation in patients with urolithiasis is to avoid the use of intraoperative fluoroscopy during stone intervention procedures. OBJECTIVE: To comparatively assess the benefits and risks of "fluoroscopy-free" and fluoroscopic endourological interventions in patients with urolithiasis. EVIDENCE ACQUISITION: A systematic review of the literature from 1970 to 2022 was performed using the MEDLINE/PubMed, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov. Primary outcomes assessed were complications and the stone-free rate (SFR). Studies reporting data on ureteroscopy and percutaneous nephrolithotomy (PCNL) were eligible for inclusion. Secondary outcomes were operative duration, hospital length of stay, conversion from a fluoroscopy-free to a fluoroscopic procedure, and requirement for an auxiliary procedure to achieve stone clearance. EVIDENCE SYNTHESIS: In total, 24 studies (12 randomised and 12 observational) out of 834 abstracts screened were eligible for analysis. There were 4564 patients with urolithiasis in total, of whom 2309 underwent a fluoroscopy-free procedure and 2255 underwent a comparative fluoroscopic procedure for treatment of urolithiasis. Pooled analysis of all procedures revealed no significant difference between the groups in SFR (p = 0.84), operative duration (p = 0.11), or length of stay (p = 0.13). Complication rates were significantly higher in the fluoroscopy group (p = 0.009). The incidence of conversion from a fluoroscopy-free to a fluoroscopic procedure was 2.84%. Similar results were noted in subanalyses for ureteroscopy (n = 2647) and PCNL (n = 1917). When only randomised studies were analysed (n = 12), the overall complication rate was significantly in the fluoroscopy group (p < 0.001). CONCLUSIONS: For carefully selected patients with urolithiasis, fluoroscopy-free and fluoroscopic endourological procedures have comparable stone-free and complication rates when performed by experienced urologists. In addition, the conversion rate from a fluoroscopy-free to a fluoroscopic endourological procedure is low at 2.84%. These findings are important for clinicians and patients, as the detrimental health effects of ionising radiation are negated with fluoroscopy-free procedures. PATIENT SUMMARY: We compared treatments for kidney stones with and without the use of radiation. We found that kidney stone procedures without the use of radiation can be safely performed by experienced urologists in patients with normal kidney anatomy. These findings are important, as they indicate that the harmful effects of radiation can be avoided during kidney stone surgery.
