Summary
Diclofenac sodium and Metamizol are the most effective medications for renal colic pain relief, offering significant benefits with minimal harm. Butylscopolamine is not recommended due to its side effects.
Area of Science:
- Urology
- Pharmacology
- Evidence-Based Medicine
Background:
- Renal colic is a common condition requiring effective pain management.
- Optimal pharmacotherapy for renal colic is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of different medications for renal colic using evidence-based medicine (EBM) parameters.
- To identify the optimal drug for renal colic treatment.
Main Methods:
- An intention-to-treat (ITT) study involving 400 outpatients with renal colic.
- Comparison of Metamizol, Diclofenac, Butylscopolamine, and placebo using the visual analogue pain scale (VAPS).
- Analysis of EBM parameters including relative risk (RR), absolute risk reduction (ARR), number needed to treat (NNT), and number needed to harm (NNH).
Main Results:
- Diclofenac sodium and Metamizol demonstrated the highest efficacy, with NNT of 1 and significant ARR (74% and 86% respectively).
- No statistically significant difference was found between Diclofenac and Metamizol.
- Butylscopolamine showed lower efficacy (ARR 18%, NNT 5) and was associated with significant side effects (NNH 2).
Conclusions:
- Diclofenac sodium is the most optimal medication for renal colic treatment, followed closely by Metamizol.
- Butylscopolamine is not recommended for treating renal colic due to unfavorable risk-benefit profile.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
01:30Urinary Tract Calculi III: Medical Management
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...
