In our study, we planned to investigate the efficacy of intradermal sterile water injections (ISWI) in the pain management of patients admitted to the emergency department due to renal colic. We also aimed to investigate patient satisfaction and reduce the use of opioid drugs with this method. A randomized controlled trial was conducted with 100 patients who presented with renal colic. Patients were divided into two groups: Group 1 received 50 mg of intravenous dexketoprofen trometamol, while Group 2 received dexketoprofen trometamol along with ISWI administered to four predetermined dermatomes (T11–L4). Pain levels were assessed using the Visual Analog Scale (VAS) at baseline and at 5, 10, 15, and 30 min post-treatment. Rescue analgesia requirements were also recorded. The primary outcome was the change in VAS pain score from baseline to 30 min after treatment. ISWI combined with dexketoprofen trometamol significantly reduced VAS scores compared to dexketoprofen trometamol alone (p < 0.05). The study was not registered, and the outcome assessment was not blinded. CONSORT methodology was not fully followed. These limitations need to be considered when interpreting the results. The combination of ISWI and dexketoprofen trometamol provides superior pain relief and reduces the need for rescue analgesia in patients with renal colic compared to dexketoprofen trometamol alone. However, because of the limitations mentioned above, no definitive conclusions can be drawn from this study.

Various drugs have been used to relieve abdominal pain in patients with renal colic. Ketamine is a popular choice as an analgesic. To compare the effectiveness of intranasal (IN) ketamine versus intravenous (IV) morphine in reducing pain in patients with renal colic. A randomized double-blind controlled trial was performed in 53 patients with renal colic recruited from the emergency department (ED) in 2015. Finally, 40 patients were enrolled in this study. Patients in the ketamine group received IN ketamine 1 mg/kg and IV placebo while patients in the control group received IV morphine 0.1mg/kg and IN placebo. Our goal was to assess visual analogue scale (VAS) changes between the 2 groups. Patients' VAS scores were reported before and 5, 15, 30min after drug injection. Before drug administration, the mean±SD VAS score was 7.40±1.18 in the morphine group (group A) and 8.35±1.30 in the ketamine group (group B) (P-value=0.021). After adjustment by the appropriate analysis, the mean±SD VAS score in group (A) and (B) at 5min were (6.07±0.47 vs 6.87±0.47; mean difference −0.79, 95% confidence interval (CI) −1.48 to −1.04) (P-value=0.025), at 15 and 30min, the mean±SD VAS score in group (A) and (B) were (5.24±0.49 vs 5.60±0.49; mean difference −0.36, 95% CI −1.08 to 0.34) and (4.02±0.59 vs 4.17±0.59; mean difference −0.15, 95% CI −1.02 to 0.71) (P-value=0.304 and 0.719) respectively. IN ketamine may be effective in decreasing pain in renal colic.

Renal colic is a prevalent cause of abdominal pain in the emergency department. Although non-steroidal anti-inflammatory drugs and opioids are used for the treatment of renal colic, some adverse effects have been reported. Therefore, desmopressin -a synthetic analogue of vasopressin- has been proposed as another treatment choice. In the present study, indomethacin in combination with nasal desmopressin was compared with indomethacin alone in the management of renal colic. Included in the study were 124 patients with initial diagnosis of renal colic and randomized to receive indomethacin suppository (100 mg) with either desmopressin intranasal spray (4 puffs, total dose of 40 micrograms) and or placebo intranasal spray. All the included patients were finally diagnosed with renal colic. There was no difference between the two groups in pain at the baseline (p = 0.4) and both treatments reduced pain successfully (p < 0.001). There was no significant difference between the two groups in pain reduction (p = 0.35). While there was significant pain reduction in both patients groups, pain reduction of NSAIDs (e.g. indomethacin) in renal colic, does not significantly improve when given in combination with desmopressin.

Ureter muscles contraction movements caused pain in renal colic. Magnesium sulphate could influence the pain by reducing acetylcholine in the nerve terminals. We have aimed to evaluate the analgesic effects of magnesium sulphate on acute renal colic pain. In this double-blind clinical trial study, the patients with renal colic pain were randomly divided into 2 groups; Group I received an intravenous infusion of 30 mg of Ketorolac and normal saline as placebo, Group II 50 mg/kg magnesium sulphate 50%/100 ml normal plus 30 mg of Ketorolac. The pain severity of patients was assessed using the visual analog scale (VAS) at baseline, and 15 and 30 min after intervention. Baseline pain score and demographic characteristics did not significantly different between the groups. After 30 min the pain score significantly reduced in both groups. While, at 15 and 30 min, mean pain score did not show statistically significant differences. Our findings indicated that Magnesium sulphate did not influence renal colic pain relief.

To assess the effectiveness of nebulized fentanyl used for analgesia in renal colic. This research was planned as a randomized, blinded study in which prospectively collected data were analyzed retrospectively to compare nebulized and intravenous (iv) fentanyl therapies. Patients with renal colic with ‘moderate’ or worse pain on a four-point verbal pain score (VPS) or with pain of 20mm or above on a 100-mm visual analogue score (VAS) at time of presentation were randomized into iv fentanyl (n=62) or nebulized fentanyl (n=53) study groups. Decreases in VAS and VPS scores at 15 and 30min compared to baseline, rescue analgesia requirements and side-effects between the groups were compared. Both iv fentanyl and nebulized fentanyl provided effective analgesia in renal colic patients at the end of 30min. However, iv fentanyl provided more rapid and more effective analgesia than nebulized fentanyl. Patients receiving iv fentanyl had lower rescue analgesia requirements than those receiving nebulized fentanyl (37.1% vs 54.7%), although the difference was not statistically significant (p=0.058). In addition, side-effects were more common in the iv fentanyl group compared to the nebulized fentanyl group (22.1% vs 9.4%), although the difference was also not significant (p=0.058). Nebulized fentanyl provides effective analgesia in patients with renal colic. However, iv fentanyl exhibits more rapid and more powerful analgesic effects than nebulized fentanyl. Nonetheless, due to its ease of use and few potential risks and side-effects the nebulized form can be used as an alternative in renal colic.

This study attempted to evaluate the efficacy of ultra-low-dose intravenous (IV) naloxone combined with IV morphine, as compared to IV morphine alone, in terms of reducing pain and morphine-induced side effects in patients with renal colic. In this double-blind clinical trial, 150 patients aged 34 to 60 years old who presented to the emergency department (ED) with renal colic were randomly allocated to either an intervention group that received ultra-low-dose IV naloxone combined with IV morphine or to a control group that received morphine plus a placebo. The severity of pain, sedation, and nausea were assessed and recorded for all patients at entrance to the ED (T1), then at 20 (T2), 40 (T3), 60 (T4), 120 (T5), and 180 (T6) minutes after starting treatment. The Numeric Rating Scale (NRS) was used for the assessment of pain and nausea intensities, and the Ramsay Sedation Scale (RSS) was used to assess sedation. A GEE model revealed that patients in the naloxone group had non-significantly reduced pain scores compared to those in the morphine group (coefficient = −0.68; 95% CI: −1.24 to −0.11, Wald X2 (1) = 5.41, p = 0.02). The sedation outcome demonstrated no statistically significant differences at T1 to T4 among patients with renal colic compared to the ones who only received morphine. At T5 and T6, 1.5% vs. 20% and 1.5% vs. 16.9% of subjects from the naloxone group versus the morphine group obtained RSS scores equal to 3, respectively (p = 0.001 and p = 0.004, respectively). Compared to patients who only received IV morphine, co-treatment of ultra-low-dose naloxone with morphine could not provide better analgesia and sedation/agitation states in renal colic patients.

We tested whether paracetamol could improve pain relief in patients visiting the emergency department with acute renal colic as compared to piroxicam, a nonsteroidal anti-inflammatory drug (NSAID). Patients with a diagnosis of acute renal colic were prospectively randomized to receive either intravenous paracetamol (1 g) or intramuscular piroxicam (20 mg). We monitored patients for visual analog scale (VAS), heart rate, arterial blood pressure, need for rescue therapy, and adverse events at different time points for 90 minutes. We recorded admission requirement and new visit for renal colic at 72 hours. The primary end point was pain relief at 90 minutes, defined as a decrease of 50% or more as compared to the initial VAS. The secondary objectives were comparison of the 2 groups for VAS at any time points and the occurrence of adverse events. Of the 226 eligible patients, 100 entered the study. Fifty patients received paracetamol and 50 received NSAID. Pain relief at 90 minutes was obtained in 40 patients receiving paracetamol (80%) and 24 (48%) receiving NSAID ( P = .002). Visual analog scale was lower in the paracetamol group since 45 minutes. Only 2 adverse events were observed. A single therapy with intravenous paracetamol more efficiently relieved pain in acute renal colic than did intramuscular piroxicam.

Objectives To assess the added-value of systematic unenhanced abdominal computed tomography (CT) on emergency department (ED) diagnosis and management accuracy compared to current practice, in elderly patients with non-traumatic acute abdominal symptoms. Methods Institutional review board approval and informed consent were obtained. This prospective study included 401 consecutive patients 75 years of age or older, admitted to the ED with acute abdominal symptoms, and investigated by early systematic unenhanced abdominal CT scan. ED diagnosis and intended management before CT, after unenhanced CT, and after contrast CT if requested, were recorded. Diagnosis and management accuracies were evaluated and compared before CT (clinical strategy) and for two conditional strategies (current practice and systematic unenhanced CT). An expert clinical panel assigned a final diagnosis and management after a 3-month follow-up. Results Systematic unenhanced CT significantly improved the accurate diagnosis (76.8% to 85%, p =1.1x10 -6 ) and management (88.5% to 95.8%, p =2.6x10 -6 ) rates compared to current practice. It allowed diagnosing 30.3% of acute unsuspected pathologies, 3.4% of which were unexpected surgical procedure requirement. Conclusions Systematic unenhanced abdominal CT improves ED diagnosis accuracy and appropriate management in elderly patients presenting with acute abdominal symptoms compared to current practice. Key Points • Systematic unenhanced CT improves significantly diagnosis accuracy compared to current practice. • Systematic unenhanced CT optimizes appropriate hospitalization by increasing the number of discharged patients. • Systematic unenhanced CT allows detection of about one-third of acute unsuspected abdominal conditions. • It should allow boosting emergency department management decision-making confidence in old patients.

This review intends to act as an overview of fructose malabsorption (FM) and its role in the aetiology of diseases including, but not limited to, irritable bowel syndrome (IBS) and infantile colic and the relationship between fructose absorption and the propagation of some cancers. IBS results in a variety of symptoms including stomach pains, cramps and bloating. Patients can be categorised into two groups, depending on whether the patients’ experiences either constipation (IBS-C) or diarrhoea (IBS-D). FM has been proposed as a potential cause of IBS-D and other diseases, such as infantile colic. However, our knowledge of FM is limited by our understanding of the biochemistry related to the absorption of fructose in the small intestine and FM’s relationship with small intestinal bacterial overgrowth. It is important to consider the dietary effects on FM and most importantly, the quantity of excess free fructose consumed. The diagnosis of FM is difficult and often requires indirect means that may result in false positives. Current treatments of FM include dietary intervention, such as low fermentable oligo-, di-, monosaccharides and polyols diets and enzymatic treatments, such as the use of xylose isomerase. More research is needed to accurately diagnose and effectively treat FM. This review is designed with the goal of providing a detailed outline of the issues regarding the causes, diagnosis and treatment of FM.

This study was conducted to evaluate colic pain as a prognostic pretreatment factor that can influence ureter stone clearance and to estimate the probability of stone-free status in shock wave lithotripsy (SWL) patients with a ureter stone. We retrospectively reviewed the medical records of 1,418 patients who underwent their first SWL between 2005 and 2013. Among these patients, 551 had a ureter stone measuring 4-20 mm and were thus eligible for our analyses. The colic pain as the chief complaint was defined as either subjective flank pain during history taking and physical examination. Propensity-scores for established for colic pain was calculated for each patient using multivariate logistic regression based upon the following covariates: age, maximal stone length (MSL), and mean stone density (MSD). Each factor was evaluated as predictor for stone-free status by Bayesian and non-Bayesian logistic regression model. After propensity-score matching, 217 patients were extracted in each group from the total patient cohort. There were no statistical differences in variables used in propensity- score matching. One-session success and stone-free rate were also higher in the painful group (73.7% and 71.0%, respectively) than in the painless group (63.6% and 60.4%, respectively). In multivariate non-Bayesian and Bayesian logistic regression models, a painful stone, shorter MSL, and lower MSD were significant factors for one-session stone-free status in patients who underwent SWL. Colic pain in patients with ureter calculi was one of the significant predicting factors including MSL and MSD for one-session stone-free status of SWL.
