Kidney stones are a common cause of blood in the urine and pain in the abdomen, flank, or groin. The usual dose in adults is 10 mg IV or IM every 4-6 hours as needed. Urologic complications of nonurologic medications. [55, 56] The dosage is 30-60 mg IM or 30 mg IV initially followed by 30 mg IV or IM every 6-8 hours. Corticosteroids have also been considered and tested for MET, though they are not used in current practices due to concerns about unwanted potential side effects.breakthrough pain.

One had extracorporeal shock wave lithotripsy for removal of residual calculi. A stone chemical analysis together with serum and appropriate 24-hour urine metabolic tests can identify the etiology in more than 95% of patients. Normal saline should be used for this procedure, as opposed to sterile water, to prevent electrolyte disturbances and hemolysis. 2008 Nov-Dec. 103(6):665-8.

It involves a three-port access system, similar to other renal procedures. The 2016 American Urological Association (AUA)/Endourological Society guidelines provide more specific indications for surgical treatment. Stone prevention should be considered most strongly in patients who have risk factors for increased stone activity, such as the following: In 2016, the American Urological Association/Endourological Society issued general management guidelines for the various presentations of stones that can be managed conservatively.

[1] Recent studies have found them more effective, less likely to require additional pain medications when used,and in the setting of a growing opioid epidemic providers must do their part to minimize patient exposure to the addictive potential of narcotics. They recommend considering a course of an alpha-blocker for patients with ureteral colic, unless it is medically contraindicated. time. [QxMD MEDLINE Link]. [95], Another instrument introduced in recent years is the StoneBreaker, which is a novel handheld pneumatic lithotripter powered by compressed carbon dioxide. Parenteral narcotics are another mainstay of analgesia for patients with acute renal colic. A stone less than 4 mm in diameter has an 80% chance of spontaneous passage; this falls to 20% for stones larger than 8 mm in diameter. [Full Text]. Wen CC, Nakada SY. 152(1):26-8. 2007 Oct. 290(10):1315-23. Next, the incision is made at the previously marked area and the stones are removed. Radiology. Asymptomatic kidney stones should be followed with serial imaging, and should be removed in case of growth, symptoms, urinary obstruction, recurrent infections, or lack of access to health care. A stent that is unclogged and functioning normally should show free reflux of contrast from the bladder into the stented renal pelvis. CD004137. eCollection 2022 Mar. 2007 Nov. 50(5):552-63. [Guideline] Trk C, Knoll T, Seitz C, Skolarikos A, Chapple C, McClinton S, et al. Noncontrast-enhanced CT should be considered if residual stone is suspected; this modality may help identify stone composition.31, Basic laboratory evaluations include creatinine (for renal function), ionized calcium (for hyperparathyroidism), and uric acid (for hyperuricemia); parathyroid hormone should be measured only if the serum calcium level is high.15,31 If a stone was not retrieved for analysis, additional tests should be considered: urine pH (for nephrocalcinosis and other metabolic abnormalities), microscopy of sediment from morning urine (for urine crystals that may suggest stone composition), and a test for cystinuria (especially in children because it is an inherited metabolic disorder).31, Many kidney stones are asymptomatic and found on imaging; each year, 10% to 25% become symptomatic or require intervention.5 Conservative management is an option for adults who are healthy, unfit for surgery, or pregnant, and who have access to health care and can adhere to active surveillance (imaging after six months, then annually).5,36 The patient should be referred for stone removal if symptoms, obstruction, or recurrent infection develops, or if the stone grows larger.5,36 Stone removal should be considered if the patient prefers removal to conservative management; plans to conceive in the near future; has calyceal diverticular stones, stones larger than 10 mm (possibly larger than 4 mm), or renal pathology; or is unsuited for conservative management.36, Kidney stones are becoming more prevalent in children because of increasing rates of diabetes mellitus, obesity, and hypertension in this population.24,9 Increasing age is a risk factor for kidney stones; therefore, adolescents are more likely to form stones than younger children.2 Children with kidney stones are more likely to have a metabolic, neurologic, or congenital urinary system structural abnormality; to have concomitant urinary infection; and to have recurrent stones.2,3,9,31, Urinary stasis, increased glomerular filtration rate, and elevated urine pH affect kidney stone formation in pregnant women. Cooper JT, Stack GM, Cooper TP. Stones smaller than 5 mm in diameter generally are retrieved using a stone basket, whereas tightly impacted stones or those larger than 5 mm are manipulated proximally for ESWL or are fragmented using an endoscopic direct-contact fragmentation device or a holmium laser fiber. MET with alpha-blockers also appears to improve the results of ESWL (see Surgical Care) inasmuch as the stone fragments resulting from treatment appear to clear the system more effectively. They filter waste and fluid from the blood and produce urine. World J Nephrol. Yilmaz E, Batislam E, Basar MM, Tuglu D, Ferhat M, Basar H. The comparison and efficacy of 3 different alpha1-adrenergic blockers for distal ureteral stones. A landmark is particularly important with small or barely visible stones, especially in the ureter, because the ESWL machine uses radiographic visualization to target the stone. Nephrolithiasis specifically refers to calculi in the kidneys, but renal calculi and ureteral calculi (ureterolithiasis) are often discussed in conjunction.

[44], In the case of pediatric patients with uncomplicated ureteral stones 10 mm or asymptomatic non-obstructing renal stones, active surveillance with periodic ultrasonography can be offered. Obstructive uropathy is blockage of urinary flow, which can affect one or both kidneys depending on the level of obstruction. 154(12):1381-7. A 64-year-old male with no known medical history has presented with a 2-week history of nausea, decreased appetite, flank pain, and lower extremity edema, and was found to have an elevated creatinine of 10.5 mg/dL. J Urol. In general, conservative management is recommended in the absence of hard indications for surgical intervention such as infection, intractable symptoms, severe hydronephrosis or premature induction of labor. } Jeffrey RB, Laing FC, Wing VW, Hoddick W. Sensitivity of sonography in pyonephrosis: a reevaluation. Radiol Clin North Am. Potassium citrate supplementation may correct low serum potassium levels caused by thiazide diuretics, but there is no evidence that combination therapy is more effective than monotherapy with either agent.15,31,38,39 Sodium citrate is an alternative for citrate supplementation, but the resulting excretion of sodium and calcium may partially counteract the intended effect.15,31,38 Unsweetened lemonade is a more palatable and less expensive alternative for citrate supplementation.

Kidney stones often have no definite, single cause, although several factors may increase your risk. You will also receive {ref69), Unsurprisingly, as robotic-assisted surgery becomes increasingly utilized, it has also been found useful in anatrophic nephrolithotomies. Complications occurred in six patients (15.3%). [QxMD MEDLINE Link]. Eur Urol.

Urinary calculi composed predominantly of calcium cannot be dissolved with current medical therapy; however, medical therapy is important in the long-term chemoprophylaxis of further calculus growth or formation. Porpiglia F, Ghignone G, Fiori C, Fontana D, Scarpa RM. Relative indications to consider for a possible admission include comorbid conditions (eg, diabetes), dehydration requiring prolonged IV fluid therapy, renal failure, or any immunocompromised state.

[73, 1] In the same guidelines, ureteroscopy (URS) is considered the first-line therapy for mid-distal ureteral stones that require intervention, although patients should be offered ESWL if URS is declined. Note that the image provided by fiberoptics, although still acceptable, is inferior to that provided by the rod-lens optics of the rigid ureteroscope in the previous picture. J Urol.

Ibuprofen can be substituted for the ketorolac tablets recommended in the original studies. [97]. Oral ketorolac is available in 10-mg pills, but the efficacy of this form in persons with acute renal colic is less clear. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. Metoclopramide is not available as a suppository. J Stuart Wolf, Jr, MD, FACS David A Bloom Professor of Urology, Associate Chair for Urologic Surgical Services, Director, Division of Endourology and Stone Disease, Department of Urology, University of Michigan Medical School This results in a net increase in oxalate absorption and hyperoxaluria, which tends to increase new kidney stone formation in patients with calcium oxalate calculi. Once a stable regimen has been established, annual 24-hour urinalyses are adequate. Francisco Talavera, PharmD, PhD Adjunct Assistant Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Received salary from Medscape for employment. In almost all patients in whom stones form, an increase in fluid intake and, therefore, an increase in urine output is recommended. Conservative management is indicated if referral is not necessary.

Role of adjunctive medical therapy with nifedipine and deflazacort after extracorporeal shock wave lithotripsy of ureteral stones. The stent forces the fragments to pass slowly, which is more efficient and prevents clogging. J Urol. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Metoclopramide is the only antiemetic that has been specifically studied in the treatment of renal colic. Both uric acid and cystine calculi form in acidic environments. Approximately 3% of patients being treated for renal colic are reported to develop a newly acquired UTI.
