Mechanism of formation of human calcium oxalate renal stones on Randall's plaque. [Full Text]. [44]. As a rule, dietary calcium should be restricted to 1000-1200 mg/d in patients with diet-responsive hypercalciuria who form calcium stones. With medical expulsive therapy (MET), stones 5-8 mm in size often pass, especially if located in the distal ureter. Kidney Stones: Treatment and Prevention | AAFP In: Conn's Current Therapy 2020. Hydronephrosis - Causes, symptoms, diagnosis, and treatment | National 4 (2):454-7. The effect of alpha-blockers was independent of stone location within the ureter. It is also useful in patients who have multiple small calculi or pre-existing nephrostomy tubes, and following a UTI. Prevalence of kidney stones in the United States. 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. 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.

[QxMD MEDLINE Link]. American Urological Association. [67], A systematic review by Beach et al found that MET with alpha antagonists for 28 days increased the rate of stone passage, decreased the time to stone passage, and decreased the rates of hospitalization and ureteroscopy, with minimal adverse effects. Smergel E, Greenberg SB, Crisci KL, Salwen JK. This discomfort can be alleviated to some extent by pain medications, anticholinergics (eg, oxybutynin, tolterodine), alpha-blockers, and topical analgesics (eg, phenazopyridine). Of 64 patients who underwent ureteroscopic lithotripsy, 52 (81.3%) had complete fragmentation of calculi, 9 (14.1%) had retrograde calculi fragments that migrated to the renal pelvis, and 3 had inaccessible calculi due to severe ureteral tortuosity. The StoneBreaker has been shown to be more effective than the Swiss LIthoclast in the management of staghorn calculi. This is likely the single most important aspect of stone prophylaxis. The goal is a total urine volume in 24 hours in excess of 2.5 liters. Robot-assisted anatrophic nephrolithotomy with renal hypothermia for managing staghorn calculi. [QxMD MEDLINE Link].

Obstructive Nephropathy Without Hydronephrosis: Suspicion Is the Key The back-up of urine into the unilateral or bilateral kidneys, depending on the location of the obstruction, causes hydronephrosis. Kidney stone disease (nephrolithiasis) is a common problem in primary care practice. Such patients are at a reasonably low risk for recurrence if they maintain adequate fluid intake. Strongly encourage patients who have a stone at a young age (ie, < 25 y), multiple recurrences, a solitary functioning kidney, or a history of prior kidney stone surgery to obtain a 24-hour urine collection for stone prevention analysis, especially if they are motivated to comply with a long-term stone prevention program. Pregnant patients with ureteral/renal stones with well-controlled symptoms can also be observed. Hydronephrosis Causes. No patient required a blood transfusion. Whether this therapy significantly affects eventual stone passage is unknown. Braswell-Pickering EA. Ureteral smooth muscle uses an active calcium pump to produce contractions, so a calcium channel blocker such as nifedipine would be expected to relax ureteral muscle spasms.

A randomized study of 77 ED patients with ureterolithiasis found no benefit to a 14-day course of tamsulosin, though the study group was small and the average stone size was 3.6 mm, making spontaneous passage without MET highly likely. Elsevier 2020. https://www.clinicalkey.com. Hydronephrosis Hydronephrosis Hydronephrosis is swelling of one or both kidneys. 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.

The size of the stone is an important predictor of spontaneous passage. include protected health information. 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. Repeat urine cultures and imaging studies should be performed to assess for ureteral obstruction and perforation, and the degree of circulating blood volume should be evaluated for ongoing hemorrhage. [QxMD MEDLINE Link]. 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. It has no anxiolytic activity and is less sedating than other centrally acting dopamine antagonists. Avoid ordering computed tomography of the abdomen and pelvis in young (younger than 50 years), otherwise healthy emergency department patients with histories of kidney stones or ureterolithiasis who present with symptoms consistent with uncomplicated renal colic.
