Effect of climate on emergency department admissions for renal colic: a comparative analysis of sedentary and non-sedentary lifestyles.

OBJECTIVE: To investigate the impact of climate and seasonal variations on emergency department (ED) admissions for renal colic, while specifically comparing the differences between individuals with sedentary and non-sedentary lifestyles. PATIENTS AND METHODS: A retrospective, single center study was conducted. Between the years 2017- 2020, medical records of patients admitted to the ED with renal colic, found to harbor ureteric stones on CT scans, were examined. Data on patients' occupational activities was collected through telephone questionnaires. Patients were categorized into two groups: sedentary and active. Precise weather data was obtained from the Israeli Meteorological Service website. The monthly average daily maximum temperatures were calculated. RESULTS: In the final sample of 560 participants, 285 were in the sedentary group, and 275 were in the active group. The study population consisted of 78.1% males and 21.9% females, with consistent gender ratios in both occupational groups. Prevalence of uric acid stones was higher in the sedentary group (p < 0.05). While there was a slight increase in admissions during the summer, seasonal distribution did not significantly differ among occupational groups. The study found no significant differences in admissions across different temperature ranges. Both groups exhibited a pattern of increased referrals during the summer and reduced referrals in the colder winter months. The baseline data revealed notable differences between the sedentary and active groups, particularly in the prevalence of uric acid stones. CONCLUSIONS: Climate factors, including temperature and seasonal variations, had limited impact on ED admissions for renal colic in patients with kidney stones, irrespective of their sedentary or active lifestyles. Both groups exhibited similar admission patterns, with a higher rate of admissions during the summer and a lower rate of admissions during the winter.

Opioid prescribing requirements to minimize unused medications after an emergency department visit for acute pain: a prospective cohort study.

BACKGROUND: Unused opioid prescriptions can be a driver of opioid misuse. Our objective was to determine the optimal quantity of opioids to prescribe to patients with acute pain at emergency department discharge, in order to meet their analgesic needs while limiting the amount of unused opioids. METHODS: In a prospective, multicentre cohort study, we included consecutive patients aged 18 years and older with an acute pain condition present for less than 2 weeks who were discharged from emergency department with an opioid prescription. Participants completed a pain medication diary for real-time recording of quantity, doses, and names of all analgesics consumed during a 14-day follow-up period. RESULTS: We included 2240 participants, who had a mean age of 51 years; 48% were female. Over 14 days, participants consumed a median of 5 (quartiles, 1-14) morphine 5 mg tablet equivalents, with significant variation across pain conditions (p < 0.001). Most opioid tablets prescribed (63%) were unused. To meet the opioid need of 80% of patients for 2 weeks, we found that those experiencing renal colic or abdominal pain required fewer opioid tablets (8 morphine 5 mg tablet equivalents) than patients who had fractures (24 tablets), back pain (21 tablets), neck pain (17 tablets), or other musculoskeletal pain (16 tablets). INTERPRETATION: Two-thirds of opioid tablets prescribed at emergency department discharge for acute pain were unused, whereas opioid requirements varied significantly based on the cause of acute pain. Smaller, cause-specific opioid prescriptions could provide adequate pain management while reducing the risk of opioid misuse. TRIAL REGISTRATION: ClinicalTrials.gov, no. NCT03953534.

Ramadan fasting and rates of admissions for renal colic due to urolithiasis: a retrospective case-control study.

OBJECTIVE: The impact of Ramadan fasting on the prevalence of renal colic (RC) remains controversial. This current study aimed to assess the correlation between Ramadan fasting, prevalence of RC and the rate of urgent endoscopic interventions due to urolithiasis. METHODS: This retrospective case-control study enrolled adult patients with a primary diagnosis of RC secondary to urolithiasis admitted to the emergency department during the years 2009-2019. The prevalence of RC and the rate of urgent urological interventions during Ramadan were compared with the pre- and post-Ramadan months in fasting Muslims and non-fasting non-Muslim patients. RESULTS: A total of 2781 patients with RC were included: 1014 (36.5%) were fasting Muslim and 1767 (63.5%) were non-fasting non-Muslim patients. No significant increase in RC admissions or urgent double J stent (DJS) insertions were observed between pre-Ramadan and Ramadan among fasting Muslims and non-fasting non-Muslim patients. However, fasting Muslims exhibited a significant increase of RC admissions post-Ramadan compared with Ramadan. CONCLUSIONS: There was no correlation between increased RC admissions or urgent DJS insertions when fasting Muslims were compared with non-fasting non-Muslim patients during Ramadan. There were increased RC admissions during the post-Ramadan month, which might indicate a delayed effect of fasting on RC.

Rare Case of Adrenal Hemangioma Discovered Incidentally during Renal Colic Investigation.

BACKGROUND Hemangiomas of the adrenal gland are rare benign non-functional tumors arising from the gland's vascular endothelium. Adrenal hemangiomas are rare in clinical settings, often discovered incidentally during an unrelated diagnostic investigation. CASE REPORT A 39-year-old man presented with a heterogeneous, enhancing 4.56×4.24×3.9-cm mass originating from the right adrenal gland's lateral limb, discovered incidentally on computed tomography (CT) to investigate renal colic. He was routinely followed up for 2 years with serial CT scans; the mass exhibited considerable growth compared with baseline, with a relatively stable appearance with hyperdense soft tissue component, fat, and foci of calcification. Dexamethasone suppression test demonstrated suppressed cortisol response, indicating a non-functional mass. Therefore, laparoscopic right adrenalectomy was performed, owing to the benign nature of the preoperative diagnosis of myelolipoma and mass size. The patient experienced an uneventful recovery, with no perioperative complications. The resected mass was 5×4×4 cm in size and weighed 30 g. Histopathology confirmed adrenal hemangioma. Serial sectioning revealed an encapsulated lesion with heterogeneous solid and cystic surfaces. Light microscopy examination showed dilated and congested vascular channels lined by flattened endothelium. Focal mature adipose tissue was seen. CONCLUSIONS The infrequent occurrence of adrenal hemangiomas and their nonspecific clinical and radiological presentation results in a considerable diagnostic challenge and, often, misdiagnosis. Surgical resection is usually necessary to exclude malignant disease, alleviate pressure-related symptoms, and decrease risk of retroperitoneum hemorrhage. These lesions are associated with a good prognosis. One limitation of this report is the lack of preoperative adrenal magnetic resonance imaging of the incidental adrenal mass.

[Renal colic]. / Steinkolik.

INTRODUCTION: Renal colic accounts for 5-10% of all emergency department visits, making it a common condition in acute medicine. The typical clinical presentation is an early indication of urolithiasis. DIAGNOSIS: Diagnostic measures include laboratory tests, ultrasound, and low-dose noncontrast computed tomography (CT) scans. Kidney, ureter, bladder (KUB) plain film radiography has been widely replaced by low-dose noncontrast CT with similar radiation dosage. In special patient groups such as children or pregnant women, ionizing radiation should be avoided if possible. TREATMENT: General measures involve pain management (non-steroidal anti-inflammatory agents, opioids) and empirical antibiotic treatment for suspected bacterial infection. Depending on the location/size of the stone, pharmacological stone expulsion therapy may be considered. In cases of obstructive pyelonephritis or acute renal insufficiency, early urinary drainage (JJ stent/nephrostomy) is recommended. Definitive stone removal may be performed primarily in some cases (rather small and rather distal ureterolithiasis). It is common to schedule stone removal as a secondary intervention.

High ambient temperature impact on the pattern of emergency-room visits due to renal colic in the Middle East.

Urolithiasis has a seasonal pattern, with an established increase in incidence during the summer months. This study aims to assess the impact of high ambient temperatures on emergency room (ER) visits related to renal colic (RC) in a Middle Eastern country over the past decade. Population data were extracted using the MDClone Big Data platform. We recorded demographic and clinical data on all RC-associated ER visits from January 2012 to April 2023 and calculated the heat index (HI) that combines daily average coastal plane temperatures and humidity percentages. There was a total of 12,770 ER visits (median age 48 years, 9,236 (72%) males). The number of visits increased during the hottest months (July-October), with the highest numbers recorded during August. The number of visits remained stable throughout the study. We identified a linear association between humidity and the incidence of ER visits (p = 0.002), and a non-linear association between ambient temperature (p < 0.0001) and HI (p < 0.0001). There was a direct relationship between high temperatures and ER visits on the same day (risk ratio [RR]: 1.75, p = 0.036), with a 2-day lag (RR: 1.123, p = 0.024). In Conclusion, there is a significant relationship between temperature, humidity, HI, and the number of ER visits due to RC. Adjusted resource allocation and healthcare workforce availability are essential for managing additional cases during heat waves. Clinical implications: Increased demand is expected during heatwaves and within a 2-day lag, emphasizing the importance of proactive strategies to effectively manage RC patients.

Urgent ureterorenoscopy as a primary treatment for ureteral stone: why not?

To evaluate the feasibility of urgent ureteroscopy (uURS) and elective ureteroscopy (eURS) in the management of patients with renal colic due to ureteral stones. Patients who were operated for ureteral stones between September 2020 and March 2022 were determined retrospectively. The patients who were operated within the first 24 h constituted the uURS group, while the patients who were operated after 24 h were classified as eURS. No limiting factors such as age, gender and concomitant disease were determined as inclusion criteria. Patients with bilateral or multiple ureteral stones, bleeding diathesis, patients requiring emergency nephrostomy or decompression with ureteral JJ stent, and pregnant women were not included. The two groups were compared in terms of stone-free rate, complications, and overall outcomes. According to the inclusion-exclusion criteria, a total of 572 patients were identified, including 142 female and 430 male patients. There were 219 patients in the first group, the uURS arm, and 353 patients in the eURS arm. The mean stone size was 8.1 ± 2.6. The stone-free rate was found to be 87.8% (502) in general, and 92 and 85% for uURS and eURS, respectively. No major intraoperative or postoperative complications were observed in any of the patients. Urgent URS can be performed effectively and safely as the primary treatment in patients with renal colic due to ureteral stones. In this way, the primary treatment of the patient is carried out, as well as the increased workload, additional examination, treatment and related morbidities are prevented.

Trends in Emergency Department Admissions Due to Renal Colic in the Pediatric Population: A Multicenter Study.

BACKGROUND: Pediatric urolithiasis is relatively uncommon and is generally associated with predisposing anatomic or metabolic abnormalities. In the adult population, emergency department (ED) admissions have been associated with an increase in ambient temperature. The same association has not been evaluated in the pediatric population. OBJECTIVES: To analyze trends in ED admissions due to renal colic in a pediatric population (≤ 18 years old) and to assess the possible effect of climate on ED admissions. METHODS: We conducted a retrospective, multicenter cohort study, based on a computerized database of all ED visits due to renal colic in pediatric patients. The study cohort presented with urolithiasis on imaging during their ED admission. Exact climate data was acquired through the Israeli Meteorological Service (IMS). RESULTS: Between January 2010 and December 2020, 609 patients, ≤ 18 years, were admitted to EDs in five medical centers with renal colic: 318 males (52%), 291 females (48%). The median age was 17 years (IQR 9-16). ED visits oscillated through the years, peaking in 2012 and 2018. A 6% downward trend in ED admissions was noted between 2010 and 2020. The number of ED admissions in the different seasons was 179 in autumn (30%), 134 in winter (22%), 152 in spring (25%), and 144 in summer (23%) (P = 0.8). Logistic regression multivariable analysis associated with ED visits did not find any correlation between climate parameters and ED admissions due to renal colic in the pediatric population. CONCLUSIONS: ED admissions oscillated during the period investigated and had a downward trend. Unlike in the adult population, rates of renal colic ED admissions in the pediatric population were not affected by seasonal changes or rise in maximum ambient temperature.

Role of the systemic immune-inflammation index in predicting spontaneous stone passage in patients with renal colic.

OBJECTIVES: Renal colic (RC) is one of the most frequent reasons for presentation to the emergency department (ED) and creates a high economic and medical burden. Management strategies for RC range from waiting for spontaneous passage to surgical intervention. However, factors determining spontaneous stone passage (SSP) are still poorly understood. Therefore, in this study, we aimed to investigate the role of the systemic immune-inflammatory index (SII) in predicting SSP. METHODS: We retrospectively analyzed the data of 924 patients aged over 18 years, who were diagnosed with RC in our clinic between 1 January 2019, and 30 May 2022, and had ureteral stones of ≤ 10 mm. The patients were divided into two groups according to whether they had SSP. The clinical and laboratory characteristics of the patients in the ED were evaluated. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and SII (neutrophil count x platelet count/lymphocyte count) values of the patients were calculated. Stone size and location were also recorded. RESULTS: In the univariate analysis of SSP, a ureteral stone size of ≤ 5 mm (p < 0.001), distal ureteral location (p < 0.001), SII (p < 0.001), NLR (p < 0.001), and PLR (p = 0.036) were significantly correlated with SSP. ROC analysis showed that an SII level < 721.8 (Sensitivity %82.6, Specificity %74.7, p < 0.001) was an independent predictor of SSP. CONCLUSION: Our findings showed that a low SII level was associated with SSP and could be used as a predictive marker of SSP as a more valuable parameter than NLR. SII and NLR, together with other indicators, are inflammatory markers that can be used in the clinical decision-making process for ureteral stone treatment.

Choosing Wisely audit: CT KUB ordering in emergency department renal colic presentations.

OBJECTIVE: Our aim was to safely reduce unnecessary CT KUBs (kidneys, ureters, bladder) in patients with renal colic. METHODS: This was a before and after intervention observational study of 74 patients in April 2023 and 57 patients in October 2023. RESULTS: Seventy-five per cent of patients with suspected renal colic underwent a CT KUB in the pre-audit period. Following education, an update in the ED Renal Colic Policy, electronic medical record ordering and short stay pathway, a re-audit was undertaken in October 2023 resulting in an absolute reduction of 15% of CT KUBs ordered. CONCLUSIONS: Audit interventions can reduce unnecessary CT KUBs in renal colic.

Point-of-care ultrasound associated with shorter length of stay than computed tomography for renal colic.

BACKGROUND: Despite similar diagnostic effectiveness for renal colic, computed tomography (CT) is more resource intensive than point-of-care ultrasound (PoCUS). We sought to compare Emergency Department (ED) length of stay (LOS) among patients with renal colic according to imaging modality utilized. We secondarily compared rates of infection, return ED visits, missed significant pathology, and urologic intervention. METHODS: This was a 12-month (1/1/22-12/31/22) multi-site retrospective cohort study of all patients diagnosed with renal colic who presented to the ED on days when at least one patient had a billable renal PoCUS examination performed. Patients with a history of genitourinary malignancy, pregnancy, renal transplant, hemodialysis, single kidney, prior visit for renal colic in the previous 30 days, or an incomplete workup were excluded. Median ED LOS was compared using a Wilcoxon rank sum test, and the 95% confidence limits for the difference between medians was calculated. Secondary outcomes were compared using a Fisher's Exact test. RESULTS: Of 415 patients screened, 325 were included for analysis: 150 had CT alone, 80 had PoCUS alone, 54 had PoCUS plus CT, and 41 had neither. Median LOS for PoCUS alone was 75.0 (95% CI 39.3-110.7) minutes shorter than CT alone (231.5 vs. 307.0 min, p < 0.0001). Similar rates of infection, return visits, and missed pathology occurred across all groups (p > 0.10). Urologic interventions were higher in the PoCUS plus CT (25.9%) group compared to CT alone (7.3%), PoCUS alone (2.5%), and neither (7.3%), p < 0.0001. CONCLUSION: Among patients with renal colic, PoCUS was associated with shorter ED LOS compared to CT, without differences in infection rates, return visits, or missed pathology. Patients with PoCUS plus CT had a higher rate of urologic interventions, suggesting PoCUS may have a role in identifying patients who would most benefit from CT.

Trends in Opioid and Nonsteroidal Anti-Inflammatory Drug Use for Patients with Kidney Stones in United States Emergency Departments from 2015 to 2021.

Introduction: Renal colic is frequently treated with opioids; however, narcotic analgesic use can lead to dependence and abuse. We evaluated use trends of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) for pain management of kidney stones in United States emergency departments (EDs) from 2015 to 2021. Methods: Kidney stone encounters were identified using National Hospital Ambulatory Medical Care Survey data. We applied a multistage survey weighting procedure to account for selection probability, nonresponse, and population weights. Medication use trends were estimated through logistic regressions on the timing of the encounter, adjusted for selected demographic and clinical characteristics. Results: Between 2015 and 2021, there were an estimated 9,433,291 kidney stone encounters in United States EDs. Opioid use decreased significantly (annual odds ratio [OR]: 0.87, p = 0.003), and there was no significant trend in NSAID use. At discharge, male patients were more likely than females (OR: 1.93, p = 0.001) to receive opioids, and Black patients were less likely than White patients (OR: 0.34, p = 0.010) to receive opioids. Regional variation was also observed, with higher odds of discharge prescriptions in the West (OR: 3.15, p = 0.003) and Midwest (OR: 2.49, p = 0.010), compared with the Northeast. Thirty-five percent of patients received opioids that were stronger than morphine. Conclusion: These results suggest improved opioid stewardship from ED physicians in response to the national opioid epidemic. However, regional variation as well as disparities in discharge prescriptions for Black and female patients underscore opportunities for continued efforts.

Urologic Presentation of Unicentric Pediatric Castleman Disease in the Setting of Acute Renal Colic.

An 11-year-old otherwise healthy female presented with renal colic and during computed tomography imaging evaluation, she was found to have a right distal ureteral stone with associated hydroureteronephrosis, medially deviated ureter, and 4-cm solid retroperitoneal mass. The mass was palpable on physical exam and was further categorized with magnetic resonance imaging, ultrasound, and laboratory testing. A multidisciplinary team approach, including pediatric surgery, radiology, oncology, and urology, led to the patient undergoing a right retrograde pyelogram, ureteroscopy with stent placement, and laparoscopic excision of retroperitoneal mass. Her pathology revealed lymphoid hyperplasia with histologic features of Castleman disease.

Preference for diagnosing and treating renal colic during pregnancy: a survey among Chinese urologists.

To explore the preference for diagnosing and treating renal colic during pregnancy among Chinese urologists. A questionnaire was designed using the Sojump® platform. WeChat, the largest social networking platform in China, was used to distribute the questionnaire to urologists at hospitals of all levels in China. In total, 110 responses were included. Of the respondents, 100.0% used ultrasound to diagnose renal colic during pregnancy, followed by magnetic resonance imaging (17.3%) and low-dose CT (3.6%). Phloroglucinol (80.9%) and progesterone (72.7%) were the most commonly used antispasmodics and analgesics. Opioid analgesics were not commonly used (12.7%). Most of the respondents (63.6%) indicated that no more than 20% of the patients needed surgical intervention. If surgery was unavoidable, 95.5% preferred temporary renal drainage, including ureteral stenting (92.7%) and percutaneous nephrostomy (2.7%). However, some respondents still preferred definitive stone treatment, such as ureteroscopy lithotripsy (3.6%) and percutaneous nephrolithotomy (0.9%). Moreover, there were no differences in the choices of urologists with different professional titles regarding diagnostic tools, most therapeutic medications, or surgical methods (p > 0.05). Ultrasound is the preferred tool for diagnosing renal colic during pregnancy. Low-dose CT is still not widely accepted. Pregnant patients with renal colic are initially treated conservatively. Urologists prefer ureteral stenting when there are clinical indications for intervention.

Intradermal Sterile Water Injection: Safe and Effective Alternative for Relief of Acute Renal Colic in the Emergency Department.

BACKGROUND: The optimal pain relief method for acute renal colic in the emergency department remains controversial. OBJECTIVE: We compared the safety and efficacy of intradermal sterile water injection (ISWI) to treatment with intramuscular (IM) diclofenac, intravenous (IV) opioids, and IV paracetamol in patients with acute renal colic. METHODS: This randomized, single-blind study included 320 patients with renal colic to one of four treatment groups. The first group received ISWI at four different points around the most painful flank area. Patients in the DI, PARA, and TRAM groups received 75 mg IM diclofenac, 1 g IV paracetamol, and 100 mg IV tramadol, respectively. Pain intensity was measured using a visual analog scale (VAS) before treatment and 15, 30, and 60 min after treatment. RESULTS: VAS scores 15 and 30 min after treatment were significantly lower in group ISWI than in groups DI, PARA, and TRAM. However, there were no significant differences in the decrease in the pain score at baseline and at 60 min after treatment. In addition, fewer patients required rescue analgesia in group ISWI than in group TRAM. However, no significant differences were observed between group ISWI and group DI or PARA in terms of the need for rescue analgesia. Finally, there were significantly fewer adverse events in group ISWI than in groups DI and TRAM. CONCLUSIONS: ISWI had similar efficacy, faster pain relief, and lower need for rescue analgesia compared with diclofenac, paracetamol, and tramadol for the management of acute renal colic. In addition, ISWI was well-tolerated and had no adverse effects.

Renal point-of-care ultrasound performed by ED staff with limited training and 30-day outcomes in patients with renal colic.

BACKGROUND AND AIM: Emergency Department (ED) renal point-of-care ultrasound (PoCUS) in renal colic by accredited specialists has good prognostic value. This may not be generalizable to under-resourced EDs. We investigated PoCUS in renal colic in our ED with lesser training. METHODS: We performed a single-centre health records review of adult ED patients with renal colic and PoCUS. Patients were managed by a non-ED specialist/resident doctor with no POCUS accreditation in consultation with an attending. These doctors attended a 3.5-h training session conducted by accredited attendings to examine hydronephrosis. They needed to verify their PoCUS findings with an attending during the first two weeks of their six-month posting before performing it independently. The primary outcome was 30-day urological procedures in hydronephrotic vs. non-hydronephrotic groups. Secondary outcomes were the distribution of primary outcome with grades of hydronephrosis, 30-day ED nephrolithiasis-related reattendances in hydronephrotic vs. non-hydronephrotic groups and its distribution with grades of hydronephrosis. We compared outcomes using Fisher's exact test. We also reported crude odds ratio (COR) and 95% CI of primary outcome between hydronephrotic vs. non-hydronephrotic groups. p values ≤ 0.05 were significant. RESULTS: We recruited 651 patients; 160 (24.6%) without and 491 (75.4%) with hydronephrosis. Rates of grades of hydronephrosis were: mild (76.6%), moderate (13.8%), severe (1.2%) and undifferentiated (8.4%). There was a difference in 30-day urological procedures (rates [95% CI]) in hydronephrotic vs. non-hydronephrotic groups, 11.2 [8.7-14.0]% vs. 2.5 [1.0-6.3]%; p < 0.001; COR (95% CI) 4.9 (1.8-13.8); p = 0.002. Increasing 30-day urological procedural rates were associated with increasing grade of hydronephrosis [no: 2.5%, mild: 7.7%, moderate: 23.5%, severe: 67.0% and undifferentiated: 14.6%; p < 0.001]. No differences occurred in other secondary outcomes. CONCLUSIONS: Renal PoCUS could be performed by non-ED specialist/resident doctors to identify patients without hydronephrosis who rarely required urological intervention. Hydronephrotic patients could benefit from further risk stratification.

ABSTRAIT: CONTEXTE ET OBJECTIF: L'échographie rénale au point de soin (PoCUS) dans les coliques rénales par des spécialistes agréés a une bonne valeur pronostique. Cela peut ne pas être généralisable aux SU sous-financés. Nous avons étudié PoCUS dans les coliques rénales dans notre DE avec une formation moindre. MéTHODES: Nous avons effectué un examen des dossiers médicaux d'un seul centre des patients adultes atteints de coliques rénales et de PoCUS. Les patients étaient pris en charge par un médecin résident/spécialiste non-membre de la DG sans accréditation POCUS en consultation avec un médecin traitant. Ces médecins ont assisté à une séance de formation de 3,5 heures menée par des titulaires accrédités pour examiner l'hydronéphrose. Ils devaient vérifier leurs résultats PoCUS auprès d'un assistant pendant les deux premières semaines de leur affectation de six mois avant de l'effectuer de manière indépendante. Le critère de jugement principal était des procédures urologiques de 30 jours dans les groupes hydronéphrotiques vs non-hydronephrotiques. Les critères de jugement secondaires étaient la distribution du critère de jugement primaire avec les grades d'hydronéphrose, les reattendances liées à la néphrose ED de 30 jours dans les groupes hydronéphrotiques vs non hydronéphrotiques et sa distribution avec les grades d'hydronéphrose. Nous avons comparé les résultats en utilisant le test exact de Fisher. Nous avons également signalé un rapport de cotes brut (RC) et un IC à 95 % du critère de jugement principal entre les groupes hydronéphrotiques et non hydronéphrotiques. Les valeurs de P 0,05 étaient significatives. RéSULTATS: Nous avons recruté 651 patients; 160 (24,6%) sans et 491 (75,4%) avec hydronéphrose. Les taux d'hydronéphrose étaient les suivants : légère (76,6 %), modérée (13,8 %), sévère (1,2 %) et indifférenciée (8,4 %). Il y avait une différence dans les interventions urologiques de 30 jours (taux [IC à 95 %]) dans les groupes hydronéphrotiques par rapport aux groupes non-hydronephrotiques, 11,2 [8,7-14,0] % contre 2,5 [1,0-6,3]%; p < 0,001; RCC (IC à 95 %) 4,9 (1,8-13,8); p = 0,002. L'augmentation des taux de procédures urologiques de 30 jours était associée à l'augmentation du grade d'hydronéphrose [non : 2,5%, léger : 7,7%, modéré : 23,5%, sévère : 67,0% et indifférencié : 14,6%; p < 0,001]. Aucune différence n'est survenue dans les autres critères de jugement secondaires. CONCLUSIONS: La PoCUS rénale pourrait être réalisée par des médecins non spécialistes/résidents de la D pour identifier les patients sans hydronéphrose qui ont rarement nécessité une intervention urologique. Les patients hydronéphrotiques pourraient bénéficier d'une meilleure stratification des risques.

Atomized Intranasal Ketorolac Versus Intravenous Ketorolac for the Treatment of Severe Renal Colic in the Emergency Department: A Double-Blind, Randomized Controlled Trial.

STUDY OBJECTIVE: Atomized intranasal (IN) drug administration offers an alternative to the intravenous (IV) route. We aimed to evaluate the analgesic efficacy of IN versus IV ketorolac in emergency department patients with acute renal colic. METHODS: We conducted a double-blind, randomized controlled trial on adult patients (aged 18 to 64 years) with severe renal colic and numerical rating scale pain ratings ≥7.0. They were randomly assigned (1:1) to receive single doses of either IN or IV ketorolac. Our main outcomes were differences in numerical rating scale reduction at 30 and 60 minutes. A 95% confidence interval (CI) was calculated for each mean difference, with a minimum clinically important difference set at 1.3 points. Secondary outcomes included treatment response, adverse events, rescue medications, and emergency department revisits. We analyzed using intention-to-treat. RESULTS: A total of 86 and 85 patients with similar baseline characteristics were allocated to the IV and IN groups, respectively. Mean numerical rating scale scores were 8.52 and 8.65 at baseline, 3.85 and 4.67 at 30 minutes, and 2.80 and 3.04 at 90 minutes, respectively. The mean numerical rating scale reduction differences between the IV and IN groups were 0.69 (95% CI -0.08 to 1.48) at 30 minutes and 0.10 (95% CI -0.85 to 1.04) at 60 minutes. There were no differences in secondary outcomes. CONCLUSION: Neither IN or IV ketorolac was superior to the other for the treatment of acute renal colic, and both provided clinically meaningful reductions in pain scores at 30 to 60 minutes.
