Adequate intravenous (IV) hydration is essential to minimize the nephrotoxic effects of IV contrast agents. In patients with high urine calcium levels and recurrent calcium stones, thiazide diuretics are recommended. Nonsteroidal anti-inflammatory drugs are the first choice for pain relief in patients with kidney stones. Dede O, Sancaktutar AA, Daguli M, Utanga M, Ba O, Penbegul N.

El-Gamal O, El-Bendary M, Ragab M, Rasheed M. Role of combined use of potassium citrate and tamsulosin in the management of uric acid distal ureteral calculi. Up to 75% of stones in pregnant women are composed of calcium phosphate, in contrast with other adults, in whom calcium oxalate stones are most common.5 Diagnostic and treatment options are limited during pregnancy because of risk to the fetus.5 Kidney stones may increase the risk of preterm labor and other maternal and fetal complications.37. [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. 40 (3):219-24.

The guidelines state that observation with or without medical expulsive therapy (MET) should be offered to patients with uncomplicated distal ureteral stones that are 10 mm or less in diameter. Urol Clin North Am. Chandhoke PS. If a kidney stone becomes lodged in the ureters, it may block the flow of urine and cause the kidney to swell and the ureter to spasm, which can be very painful. Each of these major factors can be measured easily with a 24-hour urine sample using one of several commercial laboratory packages now available. Nephrourol Mon. [QxMD MEDLINE Link].

Chirag N Dave, MD Physician in Sexual and Male Reproductive Medicine and Urology, Advanced Urology Institute of Georgia Multiple prospective randomized controlled studies in the urology literature have demonstrated that patients treated with oral alpha-blockers have an increased rate of spontaneous stone passage and a decreased time to stone passage. Cooper JT, Stack GM, Cooper TP. The cornerstone of ureteral colic management is analgesia, which can be achieved most expediently with parenteral narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs). [QxMD MEDLINE Link]. Diagnosis and Initial Management of Kidney Stones | AAFP Sodium bicarbonate can be used as the alkalizing agent, but potassium citrate is usually preferred because of the availability of slow-release tablets and the avoidance of a high sodium load. Kidney Int. J Urol. CD004137. Richard H Sinert, DO is a member of the following medical societies: American College of Physicians, Society for Academic Emergency MedicineDisclosure: Nothing to disclose. Anatrophic nephrolithotomy was classically an open procedure indicated for large staghorn calculi. The effect of alpha-blockers was independent of stone location within the ureter. [QxMD MEDLINE Link]. 2007 Dec. 178 (6):2418-34.

In particular, such cases include patients with pyonephrosis who have a UTI or urosepsis exacerbated by an obstructing calculus. 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. Factors that increase your risk of developing kidney stones include: Mayo Clinic does not endorse companies or products. [Guideline] Assimos DG, Krambeck A, Miller NL, et al. Imaging that includes assessment of renal drainage (eg, IVP, ultrasonography, CT scanning) is usually indicated in the following cases: If a patient older than 40 years has formed a single stone that passed spontaneously or was easily treated, follow-up care for recurrent stones may be unnecessary. Hollingsworth JM, Canales BK, Rogers MA, Sukumar S, Yan P, Kuntz GM, et al. Once a stable regimen has been established, annual 24-hour urinalyses are adequate. This site needs JavaScript to work properly. Anatrophic nephrolithotomy was performed on 25 kidneys, while 3 kidneys were approached in other ways without formal hypothermia and ischemia. Oral analgesics are insufficient to manage the pain. Nephrolithiasis - Symptoms, diagnosis and treatment - BMJ Three of four patients who underwent percutaneous nephrostomy owing to severe hydronephrosis, pyonephrosis, or uncontrolled sepsis were successfully treated. N13.2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. ESWL, the least invasive of the surgical methods of stone removal, utilizes high-energy sound waves focused on the stone to shatter it into passable fragments. Urinary tract obstruction leading to acute kidney injury is usually associated with bilateral hydroureters and hydronephrosis, often accompanied by oliguria. Open surgical excision of a stone from the urinary tract is now limited to isolated atypical cases. Renal calculi: sensitivity for detection with US. [QxMD MEDLINE Link]. Stones can then be retrieved by stone basket and/or allowed to pass spontaneously. Urology. ESWL is limited somewhat by the size and location of the calculus. Renal ultrasound showed mild prominence of the bilateral renal collecting systems with no evidence of hydronephrosis. Ann Emerg Med.

Nephrolithiasis refers to the presence of crystalline stones (calculi) within the urinary system (kidneys and ureter). 174(1):167-72. Nephrolithiasis. Ureteric stones almost always originate in the kidney but then pass down into the ureter. Disadvantages include longer hospitalization, longer convalescence, and increased requirements for blood transfusion. Ketorolac can increase methotrexate toxicity and phenytoin levels. Evaluation of the recurrent stone former. If the kidney is not working at all, kidney removal is not usually required unless there is an ongoing problem such as repeated infection. Porpiglia F, Ghignone G, Fiori C, Fontana D, Scarpa RM. Ultrasonography is then used to identify the location of the stones. 2006 Dec. 20(12):1005-9. Nephrolithiasis: acute renal colic. [54], Hollingsworth et al found that overall, passage of larger stones was 57% more likely in patients treated with an alpha-blocker compared with controls (risk ratio 1.57); the likelihood of stone passage increased by 9.8% with every 1 mm increase in stone size. Tract Sizes in Miniaturized Percutaneous Nephrolithotomy: A Systematic Review from the European Association of Urology Urolithiasis Guidelines Panel. 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. Available at http://uroweb.org/guideline/urolithiasis/. information submitted for this request. The prevalence of nephrolithiasis (kidney stones) is increasing in the United States, from one in 20 adults in 1994 to one in 11 adults in 2010.1,2 Worldwide, it is also increasing in Europe and is even higher in the hot-climate stone belt extending from the southeastern United States to northern Australia.3,4 Table 1 lists the incidence of different types of kidney stones among children and adults in developed countries.38 Most are of noninfectious etiology and are associated with low fluid intake, hot climate, and certain comorbidities and risk factors (e.g., hypertension; gout; obesity; nonalcoholic fatty liver disease; excessive intake of protein, carbohydrates, and sodium).1,4,911 Increasing exposure to these risk factors may explain the rising incidence of kidney stones and their prevalence in men, non-Hispanic whites, and persons with low socioeconomic status.1,3,4,9 The annual incidence of kidney stones is about eight cases per 1,000 adults and peaks around midlife in developed countries.3. [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. Accessed Jan. 20, 2020. Eur Urol. Overall, a balanced diet is ideal for preventing stone recurrence.15,31 The diet should be high in fiber and vegetables, with normal calcium content (1.0 to 1.2 g per day) and limited sodium (4 to 5 g per day) and animal protein (0.8 to 1.0 g per kg per day).15,31 Patients who are obese or over-weight should pursue a normal body weight through dietary modification and increased physical activity.2,15,31 Although there is limited evidence to support lifestyle modifications for the prevention of kidney stone recurrence, these changes are important for preventing comorbidities.
