The distance from the tip of the retrograde catheter to the ureteropelvic junction is measured in centimeters with a tape measure. } Given that stones smaller than 3 mm are already associated with an 85% chance of spontaneous passage, MET is probably most useful for stones 3-10 mm in size, though many urologists would argue for the addition of MET with alpha-blockers even with smaller or proximal stones due to the relative in-expense and few side effects for patients undergoing trial of passage if it can potentially avoid need for operative intervention. 1999 Sep. 162(3 Pt 1):685-7.

Ondansetron can provide a useful tool for both emergency room settings as well as at home as it is available in multiple forms including IV, dissolvable tablet, solution and pill form. During this procedure the renal artery is clamped, which raises the risk for ischemic injury, as well as reperfusion injury once the procedure is complete.

Distribution of nerves in the flank. Nephrolithiasis specifically refers to calculi in the kidneys, but renal calculi and ureteral calculi (ureterolithiasis) are often discussed in conjunction (see the images below). 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. For example, the presence of a ureteropelvic junction (UPJ) obstruction or a ureteral stricture could make passing even very small stones difficult or impossible. Copyright 2016 Elsevier Inc.

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. Oral analgesics are insufficient to manage the pain. [70], However, Hollingsworth et al propose that the findings of Pickard et al may be largely due to the high rate of spontaneous stone passage in the control group, perhaps because a large proportion of patients had smaller stones. 2012 Mar. Tract Sizes in Miniaturized Percutaneous Nephrolithotomy: A Systematic Review from the European Association of Urology Urolithiasis Guidelines Panel. Ureteric stones almost always originate in the kidney but then pass down into the ureter. [1] During pregnancy, radiation may cause teratogenesis or carcinogenesis effects. [QxMD MEDLINE Link].

If medical therapy is instituted, a 24-hour urinalysis 3 months after starting any new therapy should be performed to assess the degree of patient compliance and the adequacy of the metabolic response. Hydronephrosis occurs when there is either a blockage of the outflow of urine, or reverse flow of urine already in the bladder (called reflux) that can cause the renal pelvis to become enlarged. The dosage of the alkalizing agent should be adjusted to maintain the urinary pH between 6.5 and 7.0.

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. 166(6):1319-22. [QxMD MEDLINE Link]. [QxMD MEDLINE Link].

The pneumatic component is used to break up large stones and the ultrasound component contains a suction device, which is used for stone retrieval. Approximately 86% of kidney stones pass spontaneously; this proportion is lower for stones larger than 6 mm (59% vs. 90% for smaller stones).24 Although stones larger than 6 mm in diameter are often removed by urologists,5 these are the stones that have greatest benefit from medical expulsive therapy.27 Medical expulsive therapy with alpha blockers (e.g., tamsulosin [Flomax], 0.4 mg per day; doxazosin [Cardura], 4 mg per day) hastens and increases the likelihood of stone passage, reduces pain, and prevents surgical interventions and hospital admissions.5,27 These medications should be offered to patients with distal ureteral stones 5 to 10 mm in diameter.27 Tamsulosin is the most studied medication, but other alpha blockers seem equally effective.27 Calcium channel blockers (e.g., nifedipine) are less effective and may be no more effective than placebo.2830 Coadministration of oral corticosteroids or increasing fluid intake does not hasten stone passage or alleviate renal colic.5,19, Patients with newly diagnosed kidney stones should receive a basic evaluation consisting of a detailed medical history, serum chemistry, and urinalysis/urine culture.
