1 billion in health care-related expenditures.3 Most of the stones are small stones (<5?mm) and the respective spontaneous passage rate with just conservative treatment alone is high (up to 98% spontaneous passage rate).4 For stones >5?mm and <10?mm, the estimated spontaneous passage rate is 47%.5 The passage is also affected by the position of the stone. Overall passage rate is 25% for proximal, 45% for mid and 75% for distal ureteral stones.4 The spontaneous passage <a href="http://www.selleckchem.com/products/midostaurin-pkc412.html

For stone size of <2?mm and 4�C6?mm, the passage time is estimated to be 8?days and 22?days, respectively.6 However, a conservative approach beyond 6?weeks is not recommended in view of potential kidney damage.6,7 The most common procedures for these stones were extracorporeal shock wave lithotripsy (ESWL) and ureteroscopic lithotripsy (URSL).3 <a href="https://en.wikipedia.org/wiki/Ketanserin

Options include furosemide, calcium channel antagonists and corticosteroids, which have all been evaluated as therapies to promote ureteral stone expulsion with inconsistent results.8��-Blockers are considered to be the most effective drugs for medical expulsive therapy (MET) based on previous meta-analysis.9�C12 The major mechanism of ��-blockers is to relax the ureteral smooth muscle and facilitate expulsion of the stone. Tamsulosin, doxazocin and terazocin were commonly assessed in these meta-analyses. The usage of alfuzosin was assessed in a double-blind, placebo controlled trial, but no significant difference in spontaneous passage rate was found.13 Furthermore, almost all studies were on distal ureteral stones, the spontaneous passage for upper ureteral stones was rarely reported. The primary aim of the present study was to assess the spontaneous passage rate for both upper and lower ureteral stones using alfuzosin compared with the control. The secondary aim was to assess the pain control status of both groups. The present study was approved by the local ethical committee in March 2009 and we prospectively recruited all patients who presented with acute ureteric colic and were admitted through our acute and emergency unit.

The kidney�Cureter�Cbladder (KUB) X-ray of the patients showed opacity of size 5�C10?mm, suggestive of a ureteral stone. Non-contrast computerized tomography (NCCT) was used to confirm the presence of a radio-opaque stone with the respective size measured. The presence of perinephric stranding, degree of hydronephrosis and the level of stone position were documented by NCCT. Serum white blood cell count, serum creatinine level, and urine for routine microscopy and culture were checked.
