Pharmacol Res Perspect 2024; 12:e1175. [PMID: 38339883 PMCID: PMC10858371 DOI: 10.1002/prp2.1175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 11/20/2023] [Accepted: 01/22/2024] [Indexed: 02/12/2024] Open
Abstract
The aim of this study was to investigate the functional role of phosphodiesterase enzymes (PDE) in the isolated porcine ureter. Distal ureteral strips were mounted in organ baths and pre-contracted with 5-HT (100 μM). Upon generation of stable phasic contractions, PDE-4 and PDE-5 inhibitors were added cumulatively to separate tissues. PDE-4 inhibitors, such as rolipram (10 nM and greater) and roflumilast (100 nM and greater), resulted in significant attenuation of ureteral contractile responses, while a higher concentration of piclamilast (1 μM and greater) was required to induce a significant depressant effect. The attenuation effect by rolipram was abolished by SQ22536 (100 μM). PDE-5 inhibitors, such as sildenafil and tadalafil, were not nearly as effective and were only able to suppress the 5-HT-induced contractions at higher concentrations of 1 μM. Rolipram significantly enhanced the depressant effect of forskolin, while sodium nitroprusside-induced attenuation of contractile responses remained unchanged in the presence of tadalafil. In summary, our study demonstrates that PDE-4 inhibitors are effective in attenuating 5-HT-induced contractility in porcine distal ureteral tissues, while PDE-5 inhibitors are less effective. These findings suggest that PDE-4 inhibitors, such as rolipram, may hold promise as potential therapeutic agents for the treatment of ureteral disorders attributable to increased intra-ureteral pressure.

Heliyon 2022; 8:e10606. [PMID: 36148281 PMCID: PMC9485029 DOI: 10.1016/j.heliyon.2022.e10606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 07/09/2022] [Accepted: 09/07/2022] [Indexed: 11/17/2022] Open
Abstract
Background Perfusion index (PI) has use to monitor sympathetic response changes to pain. In this study, we aimed to evaluate the utility of using perfusion index as an objective marker of pain relief and of the need for rescue analgesia in ED patients with documented renal colic. Methods We conducted a prospective observational study between January 2020 and December 2020. The demographic characteristics of the patients, their complaints, nephrolithiasis histories, vital signs, PI, and VAS scores (on admission and after treatment) were recorded. Results A total of 144 patients were included. All patients were administered 20 mg of Tenoxicam on admission. There was a statistically significant difference between the PI (<0.001) and VAS scores (<0.001) on admission and after the administration of Tenoxicam. 43.1% (n = 62) of the patients needed rescue analgesia. Accordingly to ROC curve, the ability of both PI2 (AUC: 0.615, 95%CI 0.519-0.711, p = 0.018) and ΔPI (AUC: 0.601, 95%CI 0.508-0.694, p = 0.039) indices were determined as statistically significant. The cutoff value of the PI2 level for the prediction of the needed rescue analgesia was 4.65 and the cutoff value for ΔPI (PI2-PI1) was 2. All patients had a pain VAS score of <3 and a mean PI of 5.7 ± 2.9 at discharge from the emergency department. Conclusion In patients presenting to the emergency department with renal colic, the PI value on admission and after analgesic therapy can be helpful in assessing the severity of pain and predict the need for rescue analgesia.

Comparison of the Efficacy of Nonsteroidal Anti-Inflammatory Drugs and Opioids in the Treatment of Acute Renal Colic: A Systematic Review and Meta-Analysis. Front Pharmacol 2022; 12:728908. [PMID: 35153734 PMCID: PMC8828916 DOI: 10.3389/fphar.2021.728908] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 12/20/2021] [Indexed: 12/27/2022] Open
Abstract
Background: Although multiple randomized controlled trials (RCTs) and systematic review and meta-analysis were performed to investigate the efficiency and safety of nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids in the treatment of acute renal colic, the therapeutic regimen of renal colic is still controversial. Therefore, the aim of this study was to derive a more concise comparison of the effectiveness and safety between NSAIDs and opioids in the treatment for patients with acute renal colic by a systematic review and meta-analysis. Design: We searched PubMed, Embase, and Cochrane Central Register of controlled trials for seeking eligible studies. The pooled mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI) was calculated using the random effects model. The primary outcome was assessed according to the Grading of Recommendations Assessment, Development and Evaluation. Results: A total of 18 studies involving 3,121 participants were included in the systematic review and meta-analysis. No significant difference between the NSAID and opioid groups was observed, with changes in the visual analog scale (VAS) at 0–30 min (MD = 0.79, 95% CI: −0.51, 2.10). NSAIDs in the form of intravenous administration (IV) had no better effect on the changes in the VAS at 0–30 min, when compared to opioids (MD = 1.25, 95% Cl: −4.81, 7.3). The NSAIDs group in the form of IV had no better outcome compared to the opioids group, as well as the VAS at 30 min (MD = −1.18, 95% Cl: −3.82, 1.45; MD = −2.3, 95% Cl: −5.02, 0.42, respectively). Moreover, similar results of this outcome were also seen with the VAS at 45 min (MD = −1.36, 95% Cl: −5.24, 2.52). Besides, there was a statistical difference in the incidence of later rescue (RR = 0.76, 95% CI: 0.66, 0.89), drug-related adverse events (RR = 0.44, 95% CI: 0.27, 0.71), and vomiting (RR = 0.68, 95% CI: 0.49, 0.96). Conclusion: There is no significant difference between the NSAIDs and opioids in the treatment of renal colic in many outcomes (e.g., the VAS over different periods using different injection methods at 30 and 60 min), which has been focused on in this study. However, the patients who were treated using NSAIDs by clinicians can benefit from fewer side effects.

PLoS Med 2021; 18:e1003804. [PMID: 34570810 PMCID: PMC8504723 DOI: 10.1371/journal.pmed.1003804] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 10/11/2021] [Accepted: 09/09/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Although analgesics are initiated on hospital discharge in millions of adults each year, studies quantifying the risks of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) among older adults during this transition are limited. We sought to determine the incidence and risk of post-discharge adverse events among older adults with an opioid claim in the week after hospital discharge, compared to those with NSAID claims only. METHODS AND FINDINGS We performed a retrospective cohort study using a national sample of Medicare beneficiaries age 65 and older, hospitalized in United States hospitals in 2016. We excluded beneficiaries admitted from or discharged to a facility. We derived a propensity score that included over 100 factors potentially related to the choice of analgesic, including demographics, diagnoses, surgeries, and medication coadministrations. Using 3:1 propensity matching, beneficiaries with an opioid claim in the week after hospital discharge (with or without NSAID claims) were matched to beneficiaries with an NSAID claim only. Primary outcomes included death, healthcare utilization (emergency department [ED] visits and rehospitalization), and a composite of known adverse effects of opioids or NSAIDs (fall/fracture, delirium, nausea/vomiting, complications of slowed colonic motility, acute renal failure, and gastritis/duodenitis) within 30 days of discharge. After propensity matching, there were 13,385 beneficiaries in the opioid cohort and 4,677 in the NSAID cohort (mean age: 74 years, 57% female). Beneficiaries receiving opioids had a higher incidence of death (1.8% versus 1.1%; relative risk [RR] 1.7 [1.3 to 2.3], p < 0.001, number needed to harm [NNH] 125), healthcare utilization (19.0% versus 17.4%; RR 1.1 [1.02 to 1.2], p = 0.02, NNH 59), and any potential adverse effect (25.2% versus 21.3%; RR 1.2 [1.1 to 1.3], p < 0.001, NNH 26), compared to those with an NSAID claim only. Specifically, they had higher relative risk of fall/fracture (4.5% versus 3.4%; RR 1.3 [1.1 to 1.6], p = 0.002), nausea/vomiting (9.2% versus 7.3%; RR 1.3 [1.1 to 1.4], p < 0.001), and slowed colonic motility (8.0% versus 6.2%; RR 1.3 [1.1 to 1.4], p < 0.001). Risks of delirium, acute renal failure, and gastritis/duodenitis did not differ between groups. The main limitation of our study is the observational nature of the data and possibility of residual confounding. CONCLUSIONS Older adults filling an opioid prescription in the week after hospital discharge were at higher risk for mortality and other post-discharge adverse outcomes compared to those filling an NSAID prescription only.

Abstract
Background Postoperative opioid prescribing has been linked with persistent opioid use. Ureteroscopy (URS) is a common urologic procedure and a potential area to focus on opioid reduction. We aim to characterize international practice patterns of opioid prescribing post URS and what measures may decrease the need for opioid prescription. Methods We developed a survey directed to members of the Endourological Society. The survey queried the frequency of opioid prescribing post URS, challenges when opioids are not prescribed, and measures thought to reduce the need for opioids. Results We received 159 responses with the majority reported practicing urology for >20 years (37.1%), and performing 10–20 ureteroscopies/month (45.3%). Forty-one percent were from the United States (US) and Canada. Sixty-six percent completed a fellowship, 84% in endourology. Twenty-six percent prescribe opioids more than half the time and the majority do so less than 10% of the time (61.6%). Thirty-eight percent had no challenges when opioids were omitted. Measures felt to decrease the need for opioids were preoperative counseling, nonsteroidal anti-inflammatory drugs use, and use of adjunct medications. After adjusting for location and type of practice, endourology fellowship completion, years of practice, and number of ureteroscopies/month, we found that respondents from the US and Canada were more likely to prescribe opioids more than half the time post URS compared to respondents from the rest of the world [odds ratio (OR): 87.5, P<0.001, 95% confidence interval (CI): 17.3–443.5]. Conclusions Despite proven feasibility of non-opioid pathway, nearly one-quarter of participants in our survey prescribe opioids >50% of the time post URS. Most important factors felt to reduce opioid prescription post URS were preoperative counseling, nonsteroidal anti-inflammatory drugs use. US and Canadian urologists were more likely to prescribe opioids >50% of the time post URS compared to the rest of the world. We believe best practice guidelines should be considered by the American and Canadian Urological Associations to address post URS opioid prescribing.

Abstract
Opioid prescribing has dramatically increased in the
United States (US) over the past two decades, fueling
the current crisis of opioid-related adverse
events and deaths.1 Understanding the potential
contributors to this increased prescribing is paramount to developing
effective strategies for preventing propagation. In this
issue of the Journal of Hospital Medicine, Burden et al. report
the results of a cross-sectional observational study investigating
the rates of opioid receipt, patient satisfaction with pain control,
and other perceptions of pain management in a sample of patients
from geographically diverse US hospitals compared with
patients hospitalized in seven other countries.2 Although cultural
influences on pain perceptions have been demonstrated by
others previously, this is the first study to measure opioid receipt
and patient satisfaction with pain control across an international
sample of hospitalized patients.

Increasing Nonsteroidal Anti-inflammatory Drugs and Reducing Opioids or Paracetamol in the Management of Acute Renal Colic: Based on Three-Stage Study Design of Network Meta-Analysis of Randomized Controlled Trials. Front Pharmacol 2019; 10:96. [PMID: 30853910 PMCID: PMC6395447 DOI: 10.3389/fphar.2019.00096] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Accepted: 01/24/2019] [Indexed: 12/28/2022] Open
Abstract
Background: Currently, although non-steroidal anti-inflammatory drugs (NSAIDs) were recommended for acute renal colic in the 2018 European Association of Urology guidelines, there are no specific NSAIDs and no specific routes of administration in this guideline. The clinical practice of advocating intravenous opioids as the initial analgesia is still common out of the fear of adverse events from NSAIDs. Objectives: To comprehensively assess the efficacy and safety of NSAIDs, opioids, paracetamol, and combination therapy for acute renal colic. Methods: Ovid MEDLINE, Ovid EMbase, the Cochrane Library, Clinical Trials Registry Platform for Clinicaltrials.gov, and WHO International Clinical Trials Registry Platform were searched through February 2, 2018. Two reviewers selected all randomized controlled trails (RCTs) regarding NSAIDs, opioids, paracetamol, combination therapy, and placebo were identified for analysis. We designed a three-stage strategy based on classification and pharmacological mechanisms in the first stage, routes of administration in the second stage, and specific drug branches with different routes in the third stage using network meta-analysis. The pain variance at 30 min was seen as the primary outcome. Results: 65 RCTs with 8633 participants were involved. Comparing different classification and pharmacological mechanisms, combination therapy with more adverse events was more efficient than NSAIDs for the primary outcomes. Opioids gave rise to more nonspecific adverse events and vomiting events. NSAIDs were superior to opioids, paracetamol, and combination therapy after a full consideration of all outcomes. Comparing different routes of administration, NSAIDs with IV or IM route ranked first from efficacy and safety perspective. Comparing different specific drug branches with different routes, ibuprofen via IV route, ketorolac via IV route and diclofenac via IM route were superior for the management of acute renal colic. The results from diclofenac using IM route were more than those from ibuprofen used with IV route and ketorolac with IV route. Conclusions: In patients with adequate renal function, diclofenac via the IM route is recommended for patients without risks of cardiovascular events. Ibuprofen and ketorolac with IV route potentially superior to diclofenac via IM route remain to be investigated. Combination therapy is an alternative choice for uncontrolled pain after the use of NSAIDs.

Abstract
OBJECTIVE One of the greatest challenges drug formulation is facing is poor bioavailability via oral route. In this regard, nasal drug delivery has been commonly used as an alternative route to improve drug bioavailability. Nefopam hydrochloride (NF) is an analgesic drug that suffers from poor bioavailability due to extensive metabolism in liver. Accordingly, the goal of the present study was to improve NF bioavailability via niosomal-based formulation designed for intranasal delivery. MATERIALS AND METHODS Vesicles were developed by mixing surfactants (Span 20, Span 40, Span 80, and Span 85) at four molar ratios of 1:1, 1:2, 1:3, and 1:4 of cholesterol to surfactant. Entrapment efficiency, particle size, zeta potential, release percentage, ex-vivo permeation parameters, and niosomes' stability were determined. Also, the pharmacokinetic parameters of the optimized formula in in-situ gel base were measured in rats. RESULTS Niosomes showed entrapment efficiency .80%, particle size ,550 nm, and zeta potential ranging from -16.8±0.13 to -29.7±0.15. The produced vesicles showed significantly higher amounts of drug permeated across nasal mucosa (2.5 folds) and prolonged NF release compared with NF solution. Stability studies of optimum formula showed nonsignificant changes in niosomes parameters over a storage period of 6 months. The in-vivo studies showed a 4.77-fold increase in bioavailability of optimized nasal niosomes compared with oral solution of drug. CONCLUSION The obtained results revealed the great ability of the produced NF-loaded nio-somes to enhance drug penetration through nasal mucosa and improve its relative bioavailability compared with NF oral solution.

Abstract
Hospital-based clinicians frequently treat acute, noncancer pain. Although opioids may be beneficial in this setting, the benefits must be balanced with the risks of adverse events, including inadvertent overdose and prolonged opioid use, physical dependence, or development of opioid use disorder. In an era of epidemic opioid use and related harms, the Society of Hospital Medicine (SHM) convened a working group to develop a consensus statement on opioid use for adults hospitalized with acute, noncancer pain, outside of the palliative, end-of-life, and intensive care settings. The guidance is intended for clinicians practicing medicine in the inpatient setting (eg, hospitalists, primary care physicians, family physicians, nurse practitioners, and physician assistants). To develop the Consensus Statement, the working group conducted a systematic review of relevant guidelines, composed a draft Statement based on extracted recommendations, and obtained feedback from external experts in hospital-based opioid prescribing, SHM members, the SHM Patient-Family Advisory Council, other professional societies, and peer-reviewers. The iterative development process resulted in a final Consensus Statement consisting of 16 recommendations covering 1) whether to use opioids in the hospital, 2) how to improve the safety of opioid use during hospitalization, and 3) how to improve the safety of opioid prescribing at hospital discharge. As most guideline recommendations from which the Consensus Statement was derived were based on expert opinion alone, the working group identified key issues for future research to support evidence-based practice.

Abstract
INTRODUCTION Patients with renal colic present to the emergency department in excruciating pain. There is variability in practice regarding the choice of initial analgesic to be used in renal colic. The aim of this article is to outline the protocol for review of the efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs), opioids and paracetamol use in renal colic pain management. METHODS AND ANALYSIS This is the protocol for a systematic review, comparing efficacy of NSAIDs, opioids and paracetamol in renal colic studied under randomised controlled trial (RCT) design. This protocol reporting is based on the PRISMA-P recommendations (PRISMA-P-checklist). We will conduct a comprehensive literature search for both peer-reviewed and grey literature published until 18 December 2016. Using a predefined search strategy, MEDLINE, Embase and Cochrane Central Register of Controlled Trials will be searched. Additional searches will include WHO International Clinical Trials Registry Platform, abstract list of relevant major conferences and the reference lists of relevant publications. Two authors will independently screen and identify the studies to be included. The RCT comparing NSAIDs versus opioids or paracetamol will be included in the review, if the age of participants in the study was >16 years and they presented with moderate to severe renal colic. Any disagreement between the screening authors will be resolved through discussion and reaching consensus; if not, a third reviewer will arbitrate. Quantitative data from homogeneous studies will be pooled in the meta-analysis using RevMan V.5.3 software. The findings of this review will be presented according to the guidelines in the Cochrane Handbook of Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. ETHICS AND DISSEMINATION Formal ethics approval is not required, as primary data will not be collected. We plan to publish the result of this review in a peer-reviewed journal.

Abstract
Kidney stones are mineral deposits in the renal calyces and pelvis that are found free or attached to the renal papillae. They contain crystalline and organic components and are formed when the urine becomes supersaturated with respect to a mineral. Calcium oxalate is the main constituent of most stones, many of which form on a foundation of calcium phosphate called Randall's plaques, which are present on the renal papillary surface. Stone formation is highly prevalent, with rates of up to 14.8% and increasing, and a recurrence rate of up to 50% within the first 5 years of the initial stone episode. Obesity, diabetes, hypertension and metabolic syndrome are considered risk factors for stone formation, which, in turn, can lead to hypertension, chronic kidney disease and end-stage renal disease. Management of symptomatic kidney stones has evolved from open surgical lithotomy to minimally invasive endourological treatments leading to a reduction in patient morbidity, improved stone-free rates and better quality of life. Prevention of recurrence requires behavioural and nutritional interventions, as well as pharmacological treatments that are specific for the type of stone. There is a great need for recurrence prevention that requires a better understanding of the mechanisms involved in stone formation to facilitate the development of more-effective drugs.

Abstract
BACKGROUND Renal colic is acute pain caused by urinary stones. The prevalence of urinary stones is between 10% and 15% in the United States, making renal colic one of the common reasons for urgent urological care. The pain is usually severe and the first step in the management is adequate analgesia. Many different classes of medications have been used in this regard including non-steroidal anti-inflammatory drugs and narcotics. OBJECTIVES The aim of this review was to assess benefits and harms of different NSAIDs and non-opioids in the treatment of adult patients with acute renal colic and if possible to determine which medication (or class of medications) are more appropriate for this purpose. Clinically relevant outcomes such as efficacy of pain relief, time to pain relief, recurrence of pain, need for rescue medication and side effects were explored. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register (to 27 November 2014) through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA Only randomised or quasi randomised studies were included. Other inclusion criteria included adult patients with a clinical diagnosis of renal colic due to urolithiasis, at least one treatment arm included a non-narcotic analgesic compared to placebo or another non-narcotic drug, and reporting of pain outcome or medication adverse effect. Patient-rated pain by a validated tool, time to relief, need for rescue medication and pain recurrence constituted the outcomes of interest. Any adverse effects (minor or major) reported in the studies were included. DATA COLLECTION AND ANALYSIS Abstracts were reviewed by at least two authors independently. Papers meeting the inclusion criteria were fully reviewed and relevant data were recorded in a standardized Cochrane Renal Group data collection form. For dichotomous outcomes relative risks and 95% confidence intervals were calculated. For continuous outcomes the weighted mean difference was estimated. Both fixed and random models were used for meta-analysis. We assessed the analgesic effects using four different outcome variables: patient-reported pain relief using a visual analogue scale (VAS); proportion of patients with at least 50% reduction in pain; need for rescue medication; and pain recurrence. Heterogeneity was assessed using the I² test. MAIN RESULTS A total of 50 studies (5734 participants) were included in this review and 37 studies (4483 participants) contributed to our meta-analyses. Selection bias was low in 34% of the studies or unclear in 66%; performance bias was low in 74%, high in 14% and unclear in 12%; attrition bias was low in 82% and high in 18%; selective reporting bias low in 92% of the studies; and other biases (industry funding) was high in 4%, unclear in 18% and low in 78%.Patient-reported pain (VAS) results varied widely with high heterogeneity observed. For those comparisons which could be pooled we observed the following: NSAIDs significantly reduced pain compared to antispasmodics (5 studies, 303 participants: MD -12.97, 95% CI -21.80 to - 4.14; I² = 74%) and combination therapy of NSAIDs plus antispasmodics was significantly more effective in pain control than NSAID alone (2 studies, 310 participants: MD -1.99, 95% CI -2.58 to -1.40; I² = 0%).NSAIDs were significantly more effective than placebo in reducing pain by 50% within the first hour (3 studies, 197 participants: RR 2.28, 95% CI 1.47 to 3.51; I² = 15%). Indomethacin was found to be less effective than other NSAIDs (4 studies, 412 participants: RR 1.27, 95% CI 1.01 to 1.60; I² = 55%). NSAIDs were significantly more effective than hyoscine in pain reduction (5 comparisons, 196 participants: RR 2.44, 95% CI 1.61 to 3.70; I² = 28%). The combination of NSAIDs and antispasmodics was not superior to NSAIDs only (9 comparisons, 906 participants: RR 1.00, 95% CI 0.89 to 1.13; I² = 59%). The results were mixed when NSAIDs were compared to other non-opioid medications.When the need for rescue medication was evaluated, Patients receiving NSAIDs were significantly less likely to require rescue medicine than those receiving placebo (4 comparisons, 180 participants: RR 0.35, 95% CI 0.20 to 0.60; I² = 24%) and NSAIDs were more effective than antispasmodics (4 studies, 299 participants: RR 0.34, 95% CI 0.14 to 0.84; I² = 65%). Combination of NSAIDs and antispasmodics was not superior to NSAIDs (7 comparisons, 589 participants: RR 0.99, 95% CI 0.62 to 1.57; I² = 10%). Indomethacin was less effective than other NSAIDs (4 studies, 517 participants: RR 1.36, 95% CI 0.96 to 1.94; I² = 14%) except for lysine acetyl salicylate (RR 0.15, 95% CI 0.04 to 0.65).Pain recurrence was reported by only three studies which could not be pooled: a higher proportion of patients treated with 75 mg diclofenac (IM) showed pain recurrence in the first 24 hours of follow-up compared to those treated with 40 mg piroxicam (IM) (60 participants: RR 0.05, 95% CI 0.00 to 0.81); no significant difference in pain recurrence at 72 hours was observed between piroxicam plus phloroglucinol and piroxicam plus placebo groups (253 participants: RR 2.52, 95% CI 0.15 to12.75); and there was no significant difference in pain recurrence within 72 hours of discharge between IM piroxicam and IV paracetamol (82 participants: RR 1.00, 95% CI 0.65 to 1.54).Side effects were presented inconsistently, but no major events were reported. AUTHORS' CONCLUSIONS Although due to variability in studies (inclusion criteria, outcome variables and interventions) and the evidence is not of highest quality, we still believe that NSAIDs are an effective treatment for renal colic when compared to placebo or antispasmodics. The addition of antispasmodics to NSAIDS does not result in better pain control. Data on other types of non-opioid, non-NSAID medication was scarce.Major adverse effects are not reported in the literature for the use of NSAIDs for treatment of renal colic.

Abstract
The aim of the study is to determine whether dermal scarification is equally effective for treating acute renal colic compared to diclofenac sodium intramuscular therapy. A prospective, randomized controlled study was conducted with methodologic rigor based on CONSORT criteria. A total of 291 patients, aged ≥ 18 years, suffering from acute renal colic were included in this trial and randomly assigned in two groups. Patients in the first group (A) received endodermal injection (dermal scarification) of 1 ml normal saline at the area of intensity of pain. The second group (B) received 75 mg diclofenac sodium by intramuscular injection. The success of each method defined the primary end point. Pain intensity before and after treatment was assessed using a visual analog scale. The time onset and the duration of analgesia were also recorded. There was no significant difference between the two groups regarding hematuria (p = 0.158), stone identification at KUB (p = 0.751) and mean pain intensity (p = 0.609) before treatment initiation. The method was successful in 75.5 % of patients in group A and 74.3 % of patients in group B (p = 0.812). Mean pain reduction was comparable, 5.65 ± 3.05 in group A and 5.34 ± 2.99 in group B (p = 0.379), with dermal scarification eliciting its effect considerably faster, whereas the duration of analgesia was longer in the diclofenac group (p < 0.05). In conclusion, dermal scarification could constitute an alternative method for treating renal colic as it is equally effective compared to the standard treatment of diclofenac sodium.

Abstract
OBJECTIVE To investigate the evidence for the use of hyoscine N-butylbromide (HBB) in the treatment of acute renal colic. METHODS A literature search was performed using the keywords 'hyoscine N-butylbromide', 'ureteral colic', 'spasmolytic', 'anticholinergic' and 'analgesia'. The articles were given the appropriate level of evidence according to the Oxford Centre for Evidence-Based Medicine Levels of Evidence guidelines. RESULTS The analgesic effect of HBB as monotherapy is inferior to that of opioids and/or non-steroidal anti-inflammatory drugs (NSAIDs). It does provide an analgesic and antispasmodic effect, but not as long-lasting as NSAIDs. HBB does not serve as an adjunct to opioids. Furthermore, it does not facilitate passage of ureteral stones and has no effect on expulsion rate. CONCLUSIONS HBB is often used where urinary tract smooth muscle spasm is thought to be part of the pathophysiological process. According to the evidence, administration of HBB follows non-peer-reviewed protocols which are based on empiric recommendations. Its role is still unclear, as it appears to have no advantage when used as monotherapy over established forms of analgesia. There appears to be a time-dependent relation to pain reduction following parenteral administration, but this needs to be confirmed by more prospective randomized cohorts.

Abstract
Context: Renal colic is frequently described as the worst pain ever experienced, and management of this intense pain is necessary. The object of our review was to discuss different approaches of pain control for patients with acute renal colic in the emergency department. Evidence Acquisition: Studies that discussed the treatment of renal colic pain were included in this review. We collected articles from reputable internet databases. Results: Our study showed that some new treatment approaches, such as the use of lidocaine or nerve blocks, can be used to control the severe and persistent pain of renal colic. Conclusions: Some new approaches are discussed and their impact on renal colic pain control was compared with traditional therapies. The effectiveness of the new approaches in this review is similar or even better than in traditional treatments.

Abstract
The medical impact of pain is such that much effort is being applied to develop novel analgesic drugs directed towards new targets and to investigate the analgesic efficacy of known drugs. Ongoing research requires cost-saving tools to translate basic science knowledge into clinically effective analgesic compounds. In this review we have re-examined the prediction of clinical analgesia by human experimental pain models as a basis for model selection in phase I studies. The overall prediction of analgesic efficacy or failure of a drug correlated well between experimental and clinical settings. However, correct model selection requires more detailed information about which model predicts a particular clinical pain condition. We hypothesized that if an analgesic drug was effective in an experimental pain model and also a specific clinical pain condition, then that model might be predictive for that particular condition and should be selected for development as an analgesic for that condition. The validity of the prediction increases with an increase in the numbers of analgesic drug classes for which this agreement was shown. From available evidence, only five clinical pain conditions were correctly predicted by seven different pain models for at least three different drugs. Most of these models combine a sensitization method. The analysis also identified several models with low impact with respect to their clinical translation. Thus, the presently identified agreements and non-agreements between analgesic effects on experimental and on clinical pain may serve as a solid basis to identify complex sets of human pain models that bridge basic science with clinical pain research.

Abstract
OBJECTIVES To determine whether there is a difference in time to initial analgesic for patients with acute pain from sickle cell disease (SCD) versus renal colic (RC) and to identify factors contributing to variance in time to analgesic. METHODS A retrospective cohort study of the adult emergency department (ED) patients with acute pain from SCD and RC in an urban ED (final ED discharge ICD-9 diagnosis codes were included). A structured medical record review abstracted the demographics, arrival shift, triage level, initial pain score, triage time, and time of initial analgesic dose. Data were compared with Kaplan-Meier plots of time to initial analgesic for both RC and SCD with the log-rank test to test for differences by disease category. A multivariable Cox regression model estimated differences in time to initial analgesic by disease category while controlling for other possible confounders. RESULTS Median time to initial analgesic was 80 minutes for patients with SCD (interquartile range, 48 to 145) versus 50 minutes for patients with RC (interquartile range: 30 to 96). Patients with SCD reported a higher pain score on arrival when compared with RC patients and were more frequently assigned a higher triage priority level (P=0.05). Covariates that contributed the most delays to the model were afternoon arrival [hazard ratio (HR): 0.35, P<0.01], low acuity triage level (HR: 0.42, P<0.01), SCD diagnosis (HR: 0.61, P<0.01), and inability to obtain intravenous access (HR: 0.71, P=0.01). DISCUSSION ED patients with SCD experienced longer delays in the administration of the initial analgesic compared with RC patients, despite higher arrival pain scores and triage acuity levels.

Abstract
Acute ureteral colic presents with a complex of acute and characteristic flank pain that usually indicates the presence of a stone in the urinary tract. Diagnosis and management of renal colic have undergone considerable evolution and advancement in recent years. The application of noncontrast helical computed tomography (CT) in patients with suspected ureteral colic is one major advance in the primary diagnostic process. The superior sensitivity and specificity of helical CT allow ureterolithiasis to be diagnosed without the potential side effects of contrast media. Initial management is based on three key concepts: (A) rational and fast diagnostic process (B) effective pain control (C) and understanding of the impact of stone location and size on the natural course of the disease and definitive urologic management. These concepts are discussed in this review with reference to contemporary literature.
