Detailed Description
The ureteral access sheaths (UAS) used during Retrograde Intrarenal Surgery (RIRS) were produced for easy access to the upper urinary tract. The main advantages of UAS are providing repetitive access to the ureteral and collecting duct system, decreasing intrarenal pressure, preventing bleeding-related distortion of vision by the acceleration of liquid flow, and eventually contributing toward the protection of the flexible device.
Nevertheless, there might be certain challenges during UAS placement. There are also risks, such as ureteral injury and the occurrence of ureteral stricture in the long term. However, considering the benefit/risk balance, RIRS is routinely performed in many clinics because of the ease provided by UAS.
Some problems might occur during the placement of UAS whose diameters vary between 9.5 and 14 Fr. In cases where UAS cannot be placed, manipulations can be used, such as ureteral balloon dilatation, providing access through a rigid ureteroscope with a guide wire, or dilatation with the inner sheath of the UAS, which may vary depending on the amount of personal experience. Despite such manipulations, if UAS placement is still unsuccessful, it is always more logical to place a double-J stent, enables passive dilatation, and postpone RIRS until the second operation.
This study will examine whether intramural ureteral resistance can be reduced or not and whether UAS placement can be facilitated using silodosin or not.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Silodosin group (the intervention group)
Patients will receive silodosin 8 mg one tablet per day for 3 days before their scheduled retrograde intrarenal surgery.
|
This prospective study will be conducted on patients prepared for Retrograde intrarenal surgery presented to Ain Shams University Hospital. Patients will be randomized with 1:1 ratio into 2 equal groups. Group A (the study group): Patients will receive silodosin 8 mg one tablet per day for 3 days before their scheduled retrograde intrarenal surgery. silodosin is an alpha blocker which act to dilate the ureter to facilitate access sheath placement |
Placebo Comparator: Placebo group (the control group)
Patients will receive Placebo for 3 days before their scheduled retrograde intrarenal surgery.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
ureteric access sheath placement
Time Frame: intraoperative immediate diagnosis, at the beginning of surgery.
|
to assess the success of ureteric access sheath placement as follows: 1. Direct assessment: A. Success of ureteric access sheath insertion without ureteric dilatation. B. Success of ureteric access sheath insertion with ureteric dilatation. C. Failed ureteric access sheath insertion. |
intraoperative immediate diagnosis, at the beginning of surgery.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
operative time
Time Frame: intraoperative diagnosis during the surgery from beginning of the surgery till the end of the procedure
|
time of the procedure will be recorded from the beginning of the diagnostic cystoscopy till placement of the flexible ureteroscopy
|
intraoperative diagnosis during the surgery from beginning of the surgery till the end of the procedure
|
Perioperative complication
Time Frame: till 7 days postoperative
|
regarding of both intraoperative complications in the form of ureteric mucosal tear, ureteric avulsion, residual stones, postoperative pain, dysuria, hematuria, and fever
|
till 7 days postoperative
|
Cost analysis
Time Frame: 1 day post operative
|
evaluation of the cost in both arms by comparing the price for the medication for 3 days on one arm.
and the cost of the supplies needed intraoperative for ureteric dilatation or the need for another surgical session
|
1 day post operative
