Randomization
GROUP B
The patients were randomly allocated into two equal groups by a sealed opaque envelopes and a computer-generated sequence. Group A (silodosin group) included 73 patients for whom F-URS was done with daily preoperative intake of 8 mg silodosin for 1 week. Group B (Placebo/control group) included 74 patients for whom F-URS was done with daily preoperative intake of placebo tablets. The study was a double blinded, where the surgeon was blinded to whether the patient received silodosin or not and the statistician who arranged the data was also blinded to the procedures and the patients.All patients were subjected to full history taking (age, sex, BMI) and physical examination was done on all the patients. Pre-interventional evaluation included general examination of the chest, heart and abdomen and vitals of the patient. Radiology investigation included pelvis abdominal ultrasonography, plain X-ray of the kidneys, ureters and bladder (KUB) and low-dose non-contrast computed tomography (NCCT). Laboratory investigation included urinalysis and culture and sensitivity if indicated. Routine preoperative laboratories included serum creatinine, serum urea, CBC, liver function tests and coagulation profile.
