The fragility of the fiberoptic instrument is also a concern, with some studies reporting that repairs (often very expensive) were required every 6 to 15 procedures. [Full Text]. Although many staghorn calculi are struvite (related to infection with urease-splitting bacteria), the density of this stone suggests that it may be metabolic in origin and is likely composed of calcium oxalate.

[QxMD MEDLINE Link]. 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. Hydronephrosistreatment tends to focus on clearing any present infections or blockages, draining excess urine from the kidney, determining and possibly correcting the source of what is causing the condition to exist and managing pain.

All patients with kidney stones should be screened for risk of stone recurrence with medical history, basic laboratory evaluation, and imaging. Prophylactic therapy might include limitation of dietary components, addition of stone-formation inhibitors or intestinal calcium binders, and, most importantly, augmentation of fluid intake. This effect is most severe in patients who are elderly, debilitated, or both. Parenteral narcotics are another mainstay of analgesia for patients with acute renal colic. Next, the incision is made at the previously marked area and the stones are removed. Because ureteral stones can be difficult to visualize by US, 1 the secondary finding of hydronephrosis is used to diagnose nephrolithiasis when the clinical suspicion for renal colic is high. for: Medscape.

Abnormal enlargement of a kidney, which may be caused by blockage of the ureter (such as by a kidney stone) or chronic kidney disease that prevents urine from draining into the bladder. A chemical composition analysis of the stone should be performed whenever possible, and information should be provided to motivated patients about possible 24-hour urine testing for long-term nephrolithiasis prophylaxis. In large studies comparing those two approaches, the former has been associated with higher stone-free rates (up to 100% versus 87%), lower rates of subsequent unplanned emergency department visits, and lower rates of re-hospitalization. Such patients are at a reasonably low risk for recurrence if they maintain adequate fluid intake. Dusseault BN, Croce KJ, Pais VM Jr. Radiographic characteristics of sulfadiazine urolithiasis. In another location, these calculi might have been treated with extracorporeal shockwave lithotripsy (ESWL), but, after being counseled regarding the lower success rate of ESWL for stones in a dependent location, the patient elected ureteroscopy.

Before They filter waste and fluid from the blood and produce urine. 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.
