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. Acute renal colic presents as cramping and intermittent abdominal and flank pain as kidney stones travel down the ureter from the kidney to the bladder.2 Pain is often accompanied by nausea, vomiting, and malaise; fever and chills may also be present.2 Similarity with a previous episode should increase confidence in the diagnosis, although the value of personal or family history during an episode of renal colic is not known. [QxMD MEDLINE Link]. In patients with recurrent calcium stones and low urinary citrate levels, potassium citrate therapy should be offered. Carcinogenesis (dose even < 10 mGy present a risk) and mutagenesis (500-1000 mGy doses are required, far in excess of the doses in common radiographic studies) risks increase with increasing dose but do not require a threshold dose and are not dependent on the gestational age. [QxMD MEDLINE Link]. Overuse of the more effective agents leaves only highly resistant bacteria, but failure to adequately treat a UTI complicated by an obstructing calculus can result in potentially life-threatening urosepsis and pyonephrosis. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Such renal stones are composed of varying amounts of crystalloid and organic matrix. The major drawback of stents, however, is that they are often quite uncomfortable for patients due to direct bladder irritation, spasm, and reflux. Wen CC, Nakada SY. Kidney Int. Bilateral hydronephrosis is the enlargement of the parts of the kidney that collect urine. Undiagnosed residual stone fragments and silent hydronephrosis pose potential threats in post-operative settings. 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. Fast low-angle shot. Although there is no direct evidence of its effectiveness in preventing stone recurrence, the dilution of lemon juice in water should help patients meet the recommended fluid intake.42. [44].

Likewise, starting SWL on a lower energy setting with stepwise power (and SWL sequence) ramping has also been advocated in order to achieve vasoconstriction during treatment, which prevents renal injury as well as increase SFR (stone free rates). The only other general dietary guidelines are to avoid excessive salt and protein intake. St Lezin M, Hofmann R, Stoller ML. Although desmopressin is thought to work by reducing the intraureteral pressure, it may also have some direct relaxing effect on the renal pelvic and ureteral musculature.

Share cases and questions with Physicians on Medscape consult. 2007 May. Percutaneous nephrostomy is useful in such situations. Renal calculi. Patients should receive pain medication as needed, and follow-up imaging (ultrasonography and possibly plain radiography) should be obtained once within 14 days to monitor evolving stone position and assess for hydronephrosis.5,23 Complete urinary obstruction causes irreversible loss of kidney function, but patients with well-controlled pain and no significant degree of hydronephrosis have only partial obstruction and can be followed for about four to six weeks.5,13,2326 If the stone does not pass spontaneously, the patient should be referred to a urologist for active stone removal. For patients with obstructing uric acid stones in the collecting system that do not require surgical intervention, a combination of alkalinization with tamsulosin can increase the frequency of spontaneous passage of distal ureteral uric acid stones as shown in one RCT for stones > 5 mm.

Thiazide diuretics, potassium citrate, or allopurinol should be prescribed after recurrence of calcium stones, even in the absence of metabolic abnormalities. Surgical Management of Stones: American Urological Association/Endourological Society Guideline. 18(1):82-7. The larger the stone, the lower the possibility of spontaneous passage (and thus the greater the possibility that surgery will be required), although many other factors determine what happens with a particular stone.
