Impacts of the COVID-19 outbreak on visits and treatments for patients with ureteral stones in a general hospital emergency department.

BACKGROUND: The COVID-19 is a challenge for both patients and physicians in emergency department (ED). This study was aimed to report the impacts of the COVID-19 outbreak on visits and treatments for patients with ureteral stones in a general hospital ED. METHODS: The patients with ureteral stones were collected from 24 January to 24 March 2020 during the COVID-19 outbreak in Beijing. Two periods were divided for study: 24 January to 24 February (Period 1) and 25 February to 24 March (Period 2). Data on patients' characteristics, attendance, visual analog scale (VAS) scores, stone features, and final treatment choices were retrieved from the computer and compared with the data in the same periods in 2019. RESULTS: The study included 376 patients with ureteral stones during the COVID-19 outbreak periods in 2020 and 343 patients during the same periods in 2019. Compared with the same periods in 2019, the number of patients with ureteral stones was less in Period 1 (137 vs 163) but had a rebound phenomenon in Period 2 (239 vs 180). The visit frequency was significantly reduced (2.6 ± 0.4 vs 3.6 ± 0.8, p < 0.01) and the VAS scores and the onset time increased (7.7 ± 1.3 vs 5.5 ± 1.6, p < 0.01; 7.4 ± 1.8 vs 8.2 ± 1.5, p < 0.01, respectively) in Period 1. More patients chose oral analgesics medication to release from renal colic in the COVID-19 outbreak period instead of ESWL and intravenous analgesics medication (Period 1, 54.0% vs 20.2%, p < 0.01; Period 2, 20.9% vs 13.3%, p = 0.044; respectively). However, the percentage of patients underwent endoscopy surgery in outbreak period showed no significant difference compared with that in 2019. CONCLUSION: These results showed that the COVID-19 outbreak can directly affect the visits and final treatment choices for patients with ureteral stones.

Intranasal ketamine versus intravenous morphine for pain management in patients with renal colic: a double-blind, randomized, controlled trial.

BACKGROUND: Urinary stones are a common urologic problem that can be manifested as an intense pain, known as renal colic. Pain control is an important intervention for the emergency treatment of renal colic patients. Intranasal ketamine can form a crucial part of such interventions by offering a new route for a widely-used analgesic drug. METHODS: In a double-blind, randomized, clinical trial, adults with renal colic admitted to a tertiary hospital emergency department were examined. The intervention group received 1 mg/kg intranasal (IN) ketamine and 1 ml of saline as a placebo. The control group received 0.1 mg/kg intravenous (IV) morphine and four puffs of saline as the placebo. The pain score was measured on the Numerical Rating Scale (NRS) 0, 15, 30 and 60 min after the drug administration. RESULTS: A total of 184 patients enrolled in this study in two parallel groups. The two groups did not differ significantly in terms of pain intensity at the time of their referral (P = 0.489), 15 min post-dose (P = 0.204), 30 min post-dose (P = 0.978) and 60 min post-dose (P = 0.648). CONCLUSION: IN ketamine is as effective as IV morphine for pain control in renal colic patients. No remarkable side-effects were observed for IN ketamine use in these patients.

Erector spinae plane block vs non-steroidal anti-inflammatory drugs for severe renal colic pain: A pilot clinical feasibility study.

AIM: Ultrasound-guided plane blocks are increasingly used in the multi-modal analgesic concept for reducing opioid consumption. The present study was conducted to compare the analgesic effect of intravenous non-steroidal anti-inflammatory drugs (NSAIDs) and erector spinae plane (ESP) block in renal colic patients. METHODS: In this prospective randomised study, 40 patients with renal colic pain were randomly assigned into two groups: Group NSAID (n = 20) received an intravenous infusion of 50 mg of dexketoprofen trometamol and Group ESP (n = 20) received ultrasound-guided ESP block with 30 ml 0.25% bupivacaine at the T8 level. The pain severity of patients was assessed using the visual analogue scale (VAS) at baseline, 5, 15, 30, 45 and 60 minutes after intervention. Opioid consumption, patient satisfaction and side effects were recorded. RESULTS: In the ESP group, the VAS scores were significantly lower than the NSAID group at 5, 15, 30, 45 and 60 minutes after the procedure (P < .001). Opioid consumption was significantly higher in the NSAID group compared with the ESP group (10/20 vs 0/20, respectively; P < .001). Patient satisfaction was significantly higher in the ESP group (P < .001). CONCLUSIONS: ESP block can be an alternative, efficient and safe method for the relief of acute renal colic pain.

Opiates prescribed for acute renal colic are associated with prolonged use.

PURPOSE: Patients presenting with acute renal colic may be at risk of opiate abuse. We sought to analyze prescribing patterns and identify risk factors associated with prolonged opiate use during episodes of acute renal colic. METHODS: Retrospective study of patients presenting with both a stone confirmed on imaging and an acute pain episode from 6/2017-2/2020. Opiate prescription data was obtained from a statewide prescribing database. Primary outcome was an opiate refill or new opiate prescription prior to resolution of the stone episode (either passage or surgery). Univariate and multivariate linear regression analysis was performed. RESULTS: A total of 271 patients met inclusion criteria. Mean age was 52 years and 48% had a history of nephrolithiasis. 180 (66%) patients filled a new opiate prescription during their acute stone episode. Thirty-eight (14%) patients had an existing opiate prescription within 3 months of their stone episode. Seventy-four (27%) patients refilled an opiate prescription prior to stone passage or surgery. Larger stone size, need for surgery, prolonged time to treatment, existing opiate prescription, new opiate prescription at presentation, and greater initial number of pills prescribed were associated with increased risk of requiring a refill prior to stone resolution. CONCLUSIONS: Patients prescribed new opiates for acute nephrolithiasis and those with an existing opioid prescription are likely to require refills before resolution of the stone episode. Larger stones that require surgery (not spontaneous passage) also increase the risk. Timely treatment of these patients and initial treatment with non-narcotics may reduce the risk of prolonged opiate use.

Ammi Visnaga L., a Potential Medicinal Plant: A Review.

Ammi visnaga L. (Visnaga daucoides Gaertn., Family Apiaceae), also known as Khella Baldi or toothpick weed, is an annual or biennial herb indigenous to the Mediterranean region of North Africa, Asia, and Europe. The plant is known to have been used in traditional medicine a long time ago. Nowadays, it is used in modern medicine to treat many aliments such as renal colic and coronary insufficiency, and is used as an antioxidant, antifungal, and antibacterial, with a larvicidal effect on mosquito larvae. Peer-reviewed studies show that these pharmacological activities are due its valuable chemical constituents that include mainly essential oil, polyphenolic compounds including flavonoids, as well as γ-pyrones, represented mainly by khellin and visnagin. Its essential oil is reported to have antiviral, antibacterial, and larvicidal effects, while its flavonoid content is responsible for its antioxidant activity. Its γ-pyrone content has a powerful effect on facilitating the passage of kidney stones and relieving renal colic, in addition to having a relaxant effect on smooth muscle including that of the coronary arteries. The current review represents the progress in research on A. visnaga in terms of either its chemistry or biological activities. This review represents scientific support material for the use of the plant by the pharmaceutical industry.

Kidney Stones and Risk of Narcotic Use.

PURPOSE: The rise in opioid related deaths and addiction has been linked to physician prescribing. Opioids are commonly prescribed to patients with renal colic due to nephrolithiasis. The aim of this study was to describe the relationship between nephrolithiasis and opioid use in the United States. MATERIALS AND METHODS: Using the NHANES (National Health and Nutrition Examination Survey) we analyzed the relationship between a self-reported history of kidney stones and current opioid use in a nationally representative sample. RESULTS: Current opioid use was significantly greater among those who did vs did not report a history of kidney stones (10.9%, 95% CI 9.1-12.9 vs 6.1%, 95% CI 5.4-6.8). The prevalence of opioid use increased with the number of kidney stones passed, reaching 13.7% (95% CI 11.1-16.9) in subjects who had passed 2 or more stones (p <0.001). On multivariable logistic regression analysis adjusting for age, gender, smoking status, number of health care visits in the last year and comorbid conditions nephrolithiasis was independently associated with opioid based medication use (OR 1.27, 95% CI 1.07-1.49, p = 0.006). CONCLUSIONS: The association between a history of kidney stones and current narcotic use suggests that nephrolithiasis may be a risk factor for long-term opioid use. While this study is limited by the cross-sectional design and the absence of detailed stone histories, it adds to the evidence that altering pain management strategies may be beneficial in this population.

The effect of corticosteroid on postoperative early pain, renal colic and total analgesic consumption after uncomplicated and unstented ureteroscopy: a matched-pair analysis.

PURPOSE: To evaluate the effect of corticosteroid (CS) on early postoperative pain, renal colic and total analgesic consumption after uncomplicated and unstented ureteroscopy (URS). METHODS: Data of 397 patients who underwent URS and stone fragmentation for symptomatic distal ureteral stone (≤ 15 mm) were retrospectively evaluated. After exclusion, 72 patients who received methylprednisolone (Group I) after non-stenting uncomplicated URS were matched with another 72 patients who did not receive CS (Group II). Cases were matched 1:1 ratio and the matched-pair criteria were age, stone diameter, and duration of surgery. RESULTS: Both groups were statistically similar in terms of mean age, operative time, stone size and preoperative pain score. However, the mean postoperative pain score was statistically significantly lower in group I than group II on the day of surgery (3.3 ± 1.7 vs. 3.9 ± 1.3, p = 0.012) and postoperative day 1 (2.8 ± 1.8 vs. 3.4 ± 1.3, p = 0.02), respectively. Renal colic episode development rate (4.2 vs. 13.2%, p = 0.036), parenteral analgesic requirement rate (18.1 vs. 33.3%, p = 0.001) and total parenteral analgesic consumption per patient (18 vs. 36mg, p = 0.009) were statistically lower in group I than group II on the day of surgery; however, there were no statistically significant differences on postoperative day 1. There were no statistically significant differences between groups in terms of ureteral stenting requirement and late unplanned urgent room visit rates. CONCLUSIONS: Corticosteroid after uncomplicated URS can be offered to reduce early postoperative pain, renal colic episode and total analgesic consumption.

Intravenous paracetamol vs ibuprofen in renal colic: a randomised, double-blind, controlled clinical trial.

Pain management is one of the essentials of emergency care. Renal colic secondary to urinary stone disease forms one of the most intense pain types. The present study aimed to compare the effect of intravenous ibuprofen to paracetamol in ceasing renal colic. This randomised double-blind study was composed of two intervention arms, intravenous paracetamol and intravenous ibuprofen. Study subjects were randomised to receive a single dose of either paracetamol, 1 g in 100 ml normal saline, or ibuprofen (800 mg in 100 ml normal saline) in a blinded fashion. Subjects reported pain intensity on a visual analogue scale with lines intersection multiples of ten just before the drug administration, 15 and 30 min after the study drug administration. Two hundred patients were randomised to either of two study arms: however, 97 patients in ibuprofen group and 99 patients in paracetamol groups were included into 30 minute analysis. Differences of pain improvements between two groups was 9.5 (5.4-13.7) at 15 min (p = 0.000) and 17.1 (11.9-22.5) at 30 min, those both favouring ibuprofen over paracetamol (p = 0.000). Although ten (10.1%) patients in paracetamol group needed rescue drug, there were only two (2%) patients in ibuprofen group (difference: 8%; 95% CI 0.7-16%, p = 0.02). Intravenous 800 mg ibuprofen is more effective than IV paracetamol in ceasing renal colic at 30 min.

Current practice of antibiotic utilization for renal colic in the emergency room

ABSTRACT Introduction Urinalysis (UA) in the emergency setting for patients with nephrolithiasis produces potentially confusing results leading to treatment of presumed urinary tract infections (UTIs). Our objective was to evaluate the use of antibiotics in patients with nephrolithiasis in a large network of emergency departments (EDs). Methods A retrospective analysis of all ED visits associated with an ICD-9 diagnosis of nephrolithiasis and a CT scan between 2010 and 2013 was performed. Urinalysis data, the use of IV and PO antibiotics during the ED visit and at discharge were assessed. The presence of fever, elevated serum WBCs, >5 WBCs per hpf, and/or dip positive nitrites were used as appropriate criteria for antibiotic use. Results Urinalysis data were available for 3,518 (70%) of 5,035 patients with an ED diagnosis of nephrolithiasis and CT imaging. Of these visits, 237 patients had positive nitrites (6.7%) and 864 had >5 WBCs per hpf (24.6%) with 158 (4.5%) having both findings for a total of 943 patients. Intravenous antibiotics were given to 244 patients (25.9%) and oral antibiotics were given to 629 patients (66.7 %) with positive UA findings. Of the 2,440 patients with a negative UA and no leukocytosis or fever, 86 patients (3.5%) received IV antibiotics and 533 patients (21.8%) received PO antibiotics upon discharge. Conclusions Proper treatment of nephrolithiasis in the ED includes the screening and diagnosis of concomitant UTIs. However, correct interpretation of UA studies is vital to the correct implementation of antibiotic therapy. This study suggests that 1/3 of patients were undertreated and 21.8% were over-treated.

[Acute generalized exanthematous pustulosis induced by phloroglucinol]. / Pustulose exanthématique aiguë généralisée induite par le phloroglucinol (Spasfon®).

BACKGROUND: Acute generalized exanthematous pustulosis (AGEP) is a severe drug eruption. We report herein the first case of AGEP induced by phloroglucinol (Spasfon®). PATIENTS AND METHODS: A 27-year-old pregnant woman developed a febrile exanthematous pustulosis eruption three days after treatment with intravenous phloroglucinol and paracetamol for nephritic colic. She had no previous history of psoriasis. The laboratory workup showed hyperleukocytosis with neutrophilia. A cytobacteriological sample of the pustules was negative. Skin biopsy revealed marked neutrophilic and leukocytoclastic vasculitis. Reintroduction of phloroglucinol after delivery resulted in the same clinical symptoms within a few hours of intake. A diagnosis of phloroglucinol-induced AGEP was made on the basis of intrinsic imputability of I4 (S3 C3) using the imputability criteria of Begaud et al. The outcome was favorable after withdrawal of the drug. DISCUSSION: To the best of our knowledge, this is the first case of phloroglucinol-induced AGEP confirmed by reintroduction of the drug.

Transient renal impairment in the absence of pre-existing chronic kidney disease in patients with unilateral ureteric stone impaction.

This study aims to describe the rate and characteristics of transient renal impairment in unilateral ureteric stone patients without chronic kidney disease (CKD) and to identify factors that may have influenced renal function of these patients. Unilateral ureteric stone patients who visited our hospital's emergency department from December, 2009 to December, 2015 were divided into two groups based on estimated glomerular filtration rate (eGFR): group I (patients with eGFR ≥ 60 ml/min/1.73 m2) and group II (eGFR < 60 ml/min/1.73 m2). A univariate comparison between groups I and II was performed. Multivariable logistic regression analysis was performed to determine factors that influenced renal function. There were 107 patients in group II, which constituted 5.6 % of the total patients. In the multivariable logistic regression analysis, age (p < 0.001, odds ratio [OR] = 1.069, confidence interval [CI] = 1.049-1.089), hypertension (p < 0.001, OR = 2.302, CI = 1.467-3.611), stone size (p = 0.001, OR = 1.141, CI = 1.057-1.231), white blood cell count (p = 0.001, OR = 1.132, CI = 1.055-1.215) and hematuria (p < 0.001, OR = 0.383, CI = 0.231-0.636) were found to be independent factors for renal impairment. Based on the results of this study, the rate of renal impairment was 6 % of the unilateral ureteric stone patients without pre-existing CKD. Age and hypertension were found to be independent factors for renal impairment; NSAIDs should be used cautiously or other agents for pain relief such as opioids should be considered in old aged patients with hypertension.

Restricción del ductus arterioso fetal en gestante del tercer trimestre por consumo de paracetamol / Fetal ductus arteriosus constriction in the final third of pregnancy due to paracetamol comsumption

El ductus arterioso es una derivación que conecta la arteria pulmonar con el arco aórtico el que permite la descarga del ventrículo derecho sin pasar por la alta resistencia de los pulmones. La permeabilidad del conducto arterioso se mantiene durante la gestación por las prostaglandinas producidas especialmente PGE2, que circulan a nivel local, especialmente PGE2, y la baja saturación de oxígeno fetal. Se trata de una paciente que desde la semana 20 de gestación es diagnosticada de cólico renal con la necesidad de varios ingresos y colocación de catéter doble J por parte de Urología y la cual recibió tratamiento con paracetamol intravenoso y oral. Los controles ecográficos obstétricos a los largo de la gestación fueron normales hasta que en semana 32, cuando ingresa de nuevo por cuadro sospechoso de cólico renal tratado con Paracetamol, se objetivan en ecografía hallazgos compatibles con restricción precoz del ductus arterioso. Se indicó suspender el paracetamol y los cambios se redujeron en las 48 horas posteriores y casi desaparecieron por completo una semana tras la retirada de la medicación. La gestación llegó a término y el recién nacido presentó un ecocardiograma postnatal normal. Recomendamos la restricción de los analgésicos no opiáceos en el tercer trimestre y el seguimiento con Doppler del conducto arterioso en los casos en que se requiriera usarlos(AU)

Ductus arteriosus is a derivation that connects the pulmonary artery with the aortic arch and allows the discharge from the right ventricle without passing the high resistance of lungs. Permeability of the ductus arteriosus is kept during gestation because of the production of prostaglandins, particularly PGE2, which circulates locally, and the low fetal oxygen saturation. Here is a pregnant woman who, since her 20th week of gestation was diagnosed as a renal colic case. She required several admissions to hospital and placement of double J stent in the urology service and she was treated with intravenous and oral paracetamol. Obstetric ultrasound scans throughout gestation were normal until week 32, when she was admitted to hospital again for suspected renal colic and treated again with paracetamol. At that moment, findings compatible with early ductus arteriosus constriction were observed in ultrasound. It was then decided to stop the paracetamol treatment, the changes declined in the following 48 hours and they almost disappeared completely after one week after the medication withdrawal. It was finally a term pregnancy and the postnatal echocardiogram of the newborn was normal. Restricting non-opioid analgesics in the third pregnancy trimester and the follow up of the ductus arteriosus with Doppler technique when required(AU)

The Effect of Lavender Oil in Patients with Renal Colic: A Prospective Controlled Study Using Objective and Subjective Outcome Measurements.

OBJECTIVE: To assess the usability of lavender oil as an adjuvant in the medical treatment of pain due to renal stones. METHODS: One hundred patients age 19-64 years diagnosed with renal colic were included in the study. Group 1 (n=50) received standard medical therapy (diclofenac sodium, 75 mg intramuscularly); group 2 (n=50) received aromatherapy (lavender oil) in addition to the standard medical treatment. In both groups, the severity of the pain was graded between 0 (no pain) and 10 (severe pain) by using the visual analogue scale (VAS). RESULTS: The VAS values at the beginning and at 10 and 30 minutes in group 1 were 7.70±1.61, 5.02±2.20, and 2.89±1.96, respectively; in group 2, the values were 7.83±2.02, 4.42±2.46, and 2.20±1.74, respectively. The VAS values for the male patients in group 1 at the beginning and at 10 and 30 minutes were 7.61±1.47, 4.80±2.00, and 2.67±1.74; in the female patients, the values were 7.81±1.80, 5.40±2.41, and 3.72±1.94. For the male patients in group 2, the VAS values at the beginning and at 10 and 30 minutes were 8.25±2.01, 4.93±2.72, and 2.96±1.90, respectively; for the female patients, the values were 7.52±1.94, 4.15±1.95, and 1.21±0.91, respectively. Results are presented as mean±SD. Although there was no significant difference between the VAS values at the beginning and at 10 minutes in both groups, the VAS values at 30 minutes in the group receiving aromatherapy plus conventional treatment were statistically significantly low. CONCLUSION: These findings suggest that the use of aromatherapy, which is a nonpharmacologic treatment method, as an adjuvant to conventional treatment methods will help decrease pain, particularly in female patients.

Acute generalized exanthematous pustulosis induced by piroxicam: a case report.

Acute generalized exanthematous pustulosis (AGEP) is a severe adverse cutaneous reaction characterized by an acute episode of sterile pustules over erythematous-edematous skin. The main triggering drugs are antibiotics, mainly beta-lactam and macrolides. Non-steroid anti-inflammatory drugs may rarely be responsible. We describe a case of a woman with AGEP, who presented with generalized pustulosis lesions after the use of piroxicam for renal colic. The diagnosis was confirmed by the clinical and histological correlations and the dermatosis resolved after withdrawal of the drug.

Efficacy and safety of parecoxib in the treatment of acute renal colic: a randomized clinical trial

PURPOSE: Although nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs) and opioids are effective treatments for acute renal colic, they are associated with adverse events (AEs). As cyclooxygenase-2 selective NSAIDs may provide a safer alternative, we compared the efficacy and safety of parecoxib versus an nsNSAID in subjects with acute renal colic. MATERIALS AND METHODS: Phase IV., multicenter, double-blind, noninferiority, active-controlled study: 338 subjects with acute renal colic were randomized to parecoxib 40 mg i.v. plus placebo (n = 174) or ketoprofen 100 mg IV plus placebo (n = 164). 338 subjects with acute renal colic were randomized to parecoxib 40 mg IV (n = 174) or ketoprofen 100 mg IV(n = 164) plus placebo. Subjects were evaluated 15, 30, 45, 60, 90 and 120 minutes after treatment start and 24 hours after discharge. Primary endpoint was the mean pain intensity difference (PID) at 30 minutes by visual analog scale (VAS) (per-protocol population). An ANCOVA model was used with treatment group, country, and baseline score as covariates. Non-inferiority of parecoxib to ketoprofen was declared if the lower bound of the 95 percent confidence interval (CI) for the difference between the two groups excluded the pre-established margin of 10 mm for the primary endpoint. RESULTS: Baseline demographics were similar. The mean (SD) mPID30 min was 33.84 (24.61) and 35.16 (26.01) for parecoxib and ketoprofen, respectively. For treatment difference (parecoxib-ketoprofen) the lower bound of the 95 percent CI was 6.53. The mean change from baseline in VAS 30 minutes after study medication was ~43 mm; AEs were comparable between treatments. CONCLUSIONS: Parecoxib is as effective as ketoprofen in the treatment of pain due to acute renal colic, is well tolerated, and has a comparable safety profile.
