Brief Summary

Ureteric calculi are one of the most common reasons for frequent Urolithiasis. The estimated prevalence is 8-13% of all calculi. Medical expulsive therapy (MET) is recommended by the European Association of Urology (EAU) (2013) for 5-10 mm ureteric stones to facilitate stone passage. For MET, alpha blockers, mainly tamsulosin, have shown efficacy in several randomized controlled trials. The underlying pathophysiology of this therapy is supported by the presence and distribution of adrenoreceptors in the ureter. Blocking the action of alpha-1 receptors by pharmacological agents (alpha blockers), such as alfuzosin, terazosin, doxazosin, and, most typically, tamsulosin, results in the relaxation of the ureteric smooth muscle. Ureteroscopy (URS) is the most commonly performed procedure for the treatment of ureteral calculi, with a high (\>90%) stone-free rate after a single treatment. Advancing a rigid ureteroscope into a non-dilated ureter may be difficult and cause complications. Ureteric dilatation may provide access to stones, but not in all cases, and ureteral mucosal injury up to perforation might occur.

Outcome Measures

Primary Outcomes (5)

  • Rate of patients develop spontaneous expulsion of stone

    the stone spontaneously expelled without intervension

    up to 3 weeks pre operative

  • Number of patients showing dilated ureteric orifice

    during ureteroscopy easy introduction in the ureter

    intraoperative

  • Number of patients need dilatation below stone

    difficult introduce the ureteroscope and reach the stone

    intraoperative

  • Number of patients need dormia extraction or forceps without disintegration

    that is due to dilated ureter so easy remove the stone

    intraoperative

  • Time of operation from introduction of ureteroscope until stone extraction

    to know how easy introduction and expulsion of the ureteroscope

    intraoperative

Secondary Outcomes (4)

  • Rate of patients developed side effect from tamsulosin

    up to 3 weeks pre operative

  • Rate of patients developed complication

    intraoperative

  • Number of patients show failure of ureteroscopy

    intraoperative

  • Number of patients show residual stone post ureteroscopy

    postoperative 4 weeks
