USA, 2Ferris State University, Ypsilanti, MI, be beneficial in reducing renal colic.14,16,21 One tamsulosin RCT stratified Just like the name suggests, alpha-blockers are alpha-receptor antagonists. 2007 to 2009, it was prescribed in 14% of emergency department urolithiasis visits.3 This article compiles and briefly reviews the studies, including alpha-blockers as MET with or without lithotripsy in adults with renal or ureteral when comparing 4th (135-180 days) to 1st quartile (1-45 days) Steinstrasse is an accumulation of stone fragments in the ureter typically after SWL, which can lead to obstruction. Study Selection and Data Extraction: Seven As a library, NLM provides access to scientific literature. Additional studies found through references of primary and tertiary literature. The majority of patients receiving tamsulosin passed their stone within 3 days. The following drugs have approval for treating pheochromocytomas and paragangliomas: Depending on the medication and the treated condition, you can take selective A1-blockers for extended periods. For kidney stones, they are used to relax the ureter, making the ureter wider. Alpha adrenergic receptors are concentrated in the lower ureter but they exist along the entire ureter, the investigators highlighted. Common selective A1 blockers include alfuzosin , terazosin , tamsulosin , doxazosin , silodosin , and prazosin. study). Tamsulosin, an alpha-blocker prescribed to treat prostate enlargement, is the go-to drug for stone expulsion. For this reason it is recommended to take the first dose at bedtime. Patients receiving tamsulosin required significantly less analgesia. None of these drugs, however, are FDA-approved for treating kidney stones. Patients were randomized after stent placement to receive either alfuzosin 10 mg daily or placebo for 4 weeks. Bethesda, MD 20894, Web Policies In: Walsh PC, Retik, Vaughan ED , Jr, Wein AJ., editors. Patients receiving tamsulosin reported fewer instances of colic. They enrolled 96 patients with distal ureteral stones smaller than 10 mm. Laerum E, Ommundsen OE, Gronseth JE, et al. Copyright 2023 American Academy of Family Physicians. trial), Retrograde ejaculation: alfuzosin 2 patients, tamsulosin 10 When looking at stone-free status by the end of the study, patients taking alpha blockers had much improved clearance compared with those in standard therapy (30 studies with 2,378 participants; relative risk [RR] = 1.48; number needed to treat [NNT] = 4), and also when compared head-to-head with patients taking calcium channel blockers (four studies with 3,486 participants; RR = 1.19; NNT = 4.8). hypertension. And for the two-thirds of kidney stone patients who need more than just extra hydration to pass their stones, physicians are eager to find non-surgical ways to help.

If you have side effects, your healthcare provider may have you try another alpha-blocker to see if those side effects are avoidable. Written by Dr. Saima Yunus and medically reviewed by Dr. Madhav Tiwari Published on Jan 04, 2023 and last reviewed on Feb 20, 2023 - 5 min read Abstract Alpha-blockers are used in the conservative management of distal ureteral stones. A recent meta-analysis was performed, looking at studies that compared stone passage rates in patients who were given calcium channel blockers or 1-adrenergic receptor antagonists versus controls who did not receive these medications. If you are a suitable candidate for MET, your doctor will prescribe an alpha blocker medication to be taken for up to 4 to 6 weeks. It can also cause urine to remain in your bladder, causing bladder stones and infections. The authors identified 32 randomized controlled trials (RCTs) and quasi-RCTs with 5,864 participants. stones.14-21 For the RCTs, stone sizes were Alkaline citrate salts or sodium bicarbonate are considered for this purpose, and sometimes allopurinol. well-tolerated; side effects included dizziness, headache, Alpha-blockers, or alpha adrenoreceptor antagonists, are drugs that bind to the arteries in smooth muscle and cause the muscles to relax. Porpiglia F, Destefanis P, Fiori C, et al. Copyright 2015 by the American Academy of Family Physicians. Your doctor also may prescribe an alpha blocker, which relaxes the muscles in your ureter and helps pass stones quicker and with less pain. Current studies support the use of alpha-blockers as MET without lithotripsy for Additionally, when rabbit ureters were exposed to electrical stimuli in the presence of phentolamine, there was a decrease in maximum force generated.5 When dog ureters were exposed to different compounds, including agonists and antagonists, phentolamine caused a 67% prolongation of ureteral peristaltic discharge intervals, an 84% increase in ureteral fluid bolus volume, and an 18% increase in the rate of fluid transportation.6, More recently, Sigala and colleagues4 studied 1-adrenergic receptor gene and protein expression in the proximal, middle, and distal ureter. Alpha blockers more effective for large kidney stones Review of 55 kidney stone studies finds moderate evidence to support low-risk alpha blockers in larger stones Kidney stones Nearly one in 11 Americans will have a kidney stone in their lifetime, causing pain, sometimes missed work and, often, a lot of money. This series is coordinated by Corey D. Fogleman, MD, assistant medical editor. After SWL, patients were randomized to either receive standard medical therapy, which was methylprednisolone, 16 mg twice daily for 15 days and diclofenac as needed, or standard therapy plus tamsulosin 0.4 mg. Ureteral stents are often used in the treatment of renal and ureteral stones. "Studies have shown that drinking cup of lemon juice concentrate diluted in water each day, or the juice of two lemons, can increase urine citrate and likely reduce kidney stone risk," says Dr. Eisner. Importantly, it decreases the amount of pain patients suffer while passing their stones (Table 3). trial, Blood pressure lowering efficacy of alpha-blockers for primary However, the combination of corticosteroids with a calcium channel blocker or an -blocker can also be used with precautions to prevent steroid-related complications. Ureteral urine transport: changes in bolus volume, peristaltic frequency, intraluminal pressure and volume of flow resulting from autonomic drugs. stones 5 to 10 mm.18 The tamsulosin meta-analysis included more than 1300 patients from 15 trials Upsides Tamsulosin may be used in the treatment of benign prostatic hypertrophy to improve urine flow rates and other symptoms such as hesitancy, incomplete bladder emptying, intermittency, and a weak urine stream. Additionally, -adrenergic receptor antagonists may be considered during the conservative treatment of proximal and mid-ureteral stones, and after surgical intervention of renal stones. mm in diameter pass spontaneously, patients who choose observation or MET should They can also damage the kidney tissue, which may lead to bleeding, for example. None of the patients receiving tamsulosin required hospitalization during the study, whereas 15.7% of the patients receiving phloroglucinol and 4.3% of the patients receiving nifedipine required hospitalization during the study. The stone-free rate was 70.8% for patients who received tamsulosin, compared with 33.3% for those who did not (P = .019). Only tamsulosin had a significantly shorter time to stone passage when compared with the control group. meta-analysis of a randomized controlled trial, Efficacy and safety of alfuzosin as medical In the control group, only 53.57% passed their stones, whereas the rates for the groups receiving tamsulosin, terazosin, and doxazosin were 79.31%, 78.57%, and 75.86%, respectively. in improving stone-free rate and stone exclusion time, after extracorporeal Additional studies found through Recurrence is estimated to be 50% at 5 years. Inspection of the funnel plots showed asymmetry , indicating evidence of a small study effect for stone passage , surgical intervention , and pain , but not for time to stone passage or admission to hospital . Phenylephrine was found to significantly increase the contractile force of ureteral segments. (alfuzosin, silodosin, tamsulosin) and one that evaluated all alpha-blockers Dr Hundemer and colleagues examined outcomes according to eGFR categories (90, 60-89, 30-59, and <30 mL/min/1.73 m 2 ). Physiology and pharmacology of the renal pelvis and ureter. 0.24-0.89), results not stratified for stone size, Published RCTs of MET after SWL for upper urinary stones, Short (<14 days), nonrandomized, or noncomparator studies; The stents can be associated with some morbidity, including pain and urinary symptoms. They may also reduce the urinary symptoms and pain associated with double-J ureteral stents. This is a plain English summary of an original research article. The recurrence rate for the first (days 1-45) and fourth (days 135-180) quartiles Scales CD, Jr, Smith AC, Hanley JM, Saigal CS; Urologic Diseases in America Project. Alpha-blockers promote stone passage in patients receiving shock wave lithotripsy, and may be able to relieve ureteral stent-related symptoms. When conservative management of a ureteral stone is being considered and the patient has no associated signs of infection, uncontrollable pain, or renal failure, adjuvant pharmacologic intervention has proven efficacious in improving spontaneous stone passage rate and time interval, and in reducing analgesic requirements. Tamsulosin has also been linked to a higher . examined alpha-blockers as adjunctive therapy post-lithotripsy for renal or ureteral stone progression and other causes of renal colic. The rate for rehospitalization for patients receiving tamsulosin was 10%, and none of the patients required an endoscopic procedure, whereas in the group who did not receive tamsulosin, 27.5% were rehospitalized and 13% underwent an endoscopic procedure. Their standard therapy included an injection of a narcotic and diazepam on presentation, followed by a daily NSAID. Save 2.20. Nifedipine versus tamsulosin for the management of lower ureteral stones. These include drugs such as such as tamsulosin, known as Flomax. The results were significant for all but one of the 12-week trials.15-18,21 Three RCTs found tamsulosin to treated with lithotripsy, 4 RCTs and all meta-analyses found benefit with shock wave lithotripsy (SWL) for upper urinary stones: a systematic review Dellabella M, Milanese G, Muzzonigro G. Randomized trial of the efficacy of tamsulosin, nifedipine and phloroglucinol in medical expulsive therapy for distal ureteral calculi. Authors' conclusions: For patients with ureteral stones, alpha-blockers likely increase stone clearance but probably also slightly increase the risk of major adverse events. The UK is the first country to allow OTC access to Sanofi's tadalafil-based erectile dysfunction drug Cialis following a successful switch. Contemporary practice guidelines recommend off-label use of drugs called alpha blockers to facilitate stone passage. Pharmacology of tamsulosin: saturation-binding isotherms and competition analysis using cloned alpha 1-adrenergic receptor subtypes. Pirzada AJ, Anwar A, Javed A, Memon I, Mohammad A. Cleveland Clinic is a non-profit academic medical center. On the other hand, if you find a stone > 5 mm, consideration of adding an alpha blocker to treatment is reasonable.

Patients were included in the study if they had steinstrasse in the lower ureter and if the column of stone fragments was obstructing the ureter, as determined with radiography and renal ultrasound. There were fewer instances of recurrent colic with tamsulosin, and the tamsulosin was well tolerated. Using ligand binding, they were able to show that the distal ureter had the highest density of receptors, and 1d was the most common receptor present in all portions of the ureter (Figure 1). But its not clear how effectively medication can dissolve uric acid stones. were 45.64 and 18.52, respectively, per 1000-person years.19, Reports of adverse events in the studies were rare, and no serious adverse events Drinking plenty of fluids (six to eight glasses of water every day) will help flush your urinary system.

Patients receiving tamsulosin required significantly fewer injections of diclofenac, 0.13 compared with 2.83. systolic and 5 mm Hg diastolic, according to a Cochrane review.22 This decrease in blood pressure is responsible for dizziness (3% to 19%) and Flomax is in a class of drugs called alpha-blockers. Objective: To review the literature for -blocker treatment of kidney stones.Data Sources: PubMed search performed November 15, 2017, using the following search terms: alpha-blocker, alfuzosin, silodosin, or tamsulosin AND kidney or ureteral stones. The overall stone expulsion time was three days shorter with alpha blockers than with standard therapy, with a mean expulsion time of seven rather than 10 days. PSA levels go up when the prostate becomes enlarged. The 86 patients were broken down into 3 groups: 1 group received only deflazacort (control group), 1 group received tamsulosin 0.4 mg daily, and the third group received 30 mg nifedipine slow release daily. headache, Published RCTs of alpha-blockers for ureteral stones (only 4 US Pain relievers.
