The Use of Alpha-Blockers for the Treatment of Nephrolithiasis

A total of 67 patients were included and were randomized to receive hydration and tenoxicam, an NSAID, with or without tamsulosin 0. Only tamsulosin had a significantly shorter time to stone passage when compared with the control group. The providers and patients knew if they got tamsulosin or nepholithiasis.

Importantly, it decreases the amount of pain patients suffer while passing their stones Table 3. The stones ranged in size from floma mm to 20 mm. Medical expulsive therapy using the alpha blocker tamsulosin does not aid passage of ureteral stones less than 9 mm in diameter, according to study findings published online in JAMA Internal Medicine.

Tamsulosin Ineffective for Small Ureteral Stones

Mean stone size was small 3. More patients in the placebo arm had multiple stones, more patients in the tamsulosin arm had distal ureteral stones Patients lost to follow up were excluded from the analysis. These interventions were mostly based on poor methodologic studies and meta-analyses of these flawed studies Hollingsworth Over the past years, a small number of higher-quality RCTs have been published FerrePickardFuryk There are no well done, large RDCTs to guide us.


Patients receiving tamsulosin required ureteroscopy or a second SWL less often compared with those who did not receive tamsulosin, but the difference was not statistically significant.

Stone size, location, and passage were confirmed by computed tomography. August 7, Renal colic is a common ED presentation. Here is the response I got from our urology group: However, Dellabella and colleagues 9 did show that steroids are a useful adjunct to induce more nephrolitbiasis stone expulsion. Dahm P and Hollingsworth JM.

Multicenter, randomized, double-blind, placebo-controlled study Excluded: Mean stone size was significantly greater in the group receiving fllomax, 6. Alpha blockers for treatment of ureteric stones: Dellabella and colleagues also recently compared tamsulosin, nifedipine, and phloroglucinol, a spasmolytic agent, in patients with distal ureteral stones larger than 4 mm. 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.

Alphaadrenergic receptor antagonists have some degree of selectivity for the detrusor and the distal ureter and have therefore been the next agents investigated for their potential floomax promote stone expulsion and decrease pain.

Despite these limitations, this study appears to have changed practice.

In a study of 86 patients with distal ureteral stones smaller than 1 cm, Porpiglia and associates 22 compared the effectiveness of nifedipine and tamsulosin. Age Adjusted D-Dimer Testing. Only 1 patient receiving tamsulosin experienced slight dizziness. Resim S et al Patients receiving tamsulosin reported fewer instances of colic.


Current urology guidelines recommend the addition of tamuslosin in the treatment of ureteral colic mainly based on poor quality studies and systematic reviews and meta-analyses including these poorly done studies.

A Randomized Clinical Trial. Most Popular Bundle Branch Blocks: The median time in hours to stone passage was 72 hours for the group receiving tamsulosin, and this was significantly less than the hours for the groups receiving nifedipine or phloroglucinol. Alpha-blockers have been demonstrated to increase expulsion rates of distal ureteral stones, decrease time to nephrolithiaais, and decrease need for analgesia during stone passage.

The time to passage was also not significantly different. When conservative management of nephgolithiasis 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 treatment increases clinical success rate of single extracorporeal shock wave lithotripsy of renal stones. Current guidelines by the American Urological Association recommend alpha blockers for ureteral stones 10 mm or less in diameter.

In addition, the investigators observed no significant between-group differences with respect to time to stone passage, return to work time, analgesic use, hospitalization, need for surgery, or repeat visit to the emergency department.
