OBJECTIVES To study the efficacy of alfuzosin compared with tamsulosin in the management of lower ureteral
stones.
METHODS A total of 102 patients with stones 1 cm size and located in the lower ureter were enrolled in
the present study and randomized into 3 equal groups. Group 1 patients (n = 34) received 0.4
mg tamsulosin daily, group 2 patients (n = 34) received 10 mg alfuzosin daily, and group 3
patients (n = 34) received placebo (control group). The patients were given 75 mg diclofenac
injection intramuscularly on demand and were followed up for 4 weeks.
RESULTS The average stone size for groups 1, 2, and 3 was comparable (6.17, 6.70, and 6.35 mm,
respectively). Stone expulsion was observed in 28 of 34 patients (82.3%) in group 1, 24 of 34
patients (70.5%) in group 2, and 12 of 34 patients (35.2%) in group 3. The average expulsion
time for groups 1, 2, and 3 was 12.3, 14.5, and 24.5 days, respectively. The results of both study
groups (groups 1 and 2) were superior to those in the placebo group (P = .003 and P = .001,
respectively), but the study failed to show any statistically significant differences between
tamsulosin and alfuzosin (P = .25). Alfuzosin was associated with fewer side effects than
tamsulosin, especially in terms of retrograde ejaculation.
CONCLUSIONS Medical treatment of lower ureteral calculi with tamsulosin and alfuzosin resulted in a signifi-
cantly increased stone expulsion rate, decreased expulsion time, and a reduced need for analgesic
therapy. UROLOGY 73: 706 –709, 2009. © 2009 Elsevier Inc.

ymptomatic ureterolithiasis represents the most
common condition observed by urologists in an
emergency setting.
1
Of all ureteral stones, 70% are
found in the lower third of ureter at presentation. Al-
though a watchful waiting approach can be used success-
fully for a large number of patients,
2,3
it can also result in
complications such as urinary tract infection, hydrone-
phrosis, and renal function deterioration. The use of the
watchful waiting approach has been extended with the
use of pharmacologic therapy in the form of -adrenergic
blockers to provide relief from colic pain and facilitate
stone expulsion.
4-6
Studies have revealed the presence of
1
-adrenergic
receptors in the ureter. The density of
1
-adrenergic
receptors in ureteral smooth muscle cells is significantly
greater than other adrenergic receptors.
1
-Adrenergic
antagonists have been proved to inhibit basal tone, peri-
staltic frequency, and ureteral contractions in the intra-
mural part of ureter.

Several clinical trials have shown good results with the use
of selective -blockers in the treatment of lower ureteral
stones.
7-9
Most of these trials have studied the efficacy of
tamsulosin on lower ureteral stones. We performed a pro-
spective randomized study comparing alfuzosin and tamsu-
losin for the relief of ureteral colic and in facilitating the
spontaneous expulsion of distal ureteral stones.
MATERIAL AND METHODS
From September 2004 to August 2007, 102 patients presenting
with stone 1 cm in size located in the distal part of the ureter
(juxtavesical part and ureterovesical junction) were included in
the present study. The exclusion criteria included urinary tract
infection, severe hydroureteronephrosis, diabetes mellitus, mul-
tiple stones, hypotension, pregnancy, previous spontaneous
stone expulsion, distal ureteral surgery, and history of intake of
any of the following drugs: warfarin, -adrenergic blockers,
calcium antagonist, steroids, and cimetidine. All patients were
evaluated with plain x-rays of the abdomen, ultrasonography of
the urinary system, intravenous urography, and noncontrast
computed tomography in selected patients.
