Participants randomized to this arm will receive 0.4 mg/day tamsulosin hydrochloride from 5 days prior to the operation until hospital discharge.
Drug: Tamsulosin hydrochloride
Participants will receive 0.4 mg/day tamsulosin hydrochloride from 5 days prior to the operation until hospital discharge.
Placebo Comparator: Placebo
Participants randomized to this arm will receive a daily placebo capsule matching the active study drug from 5 days prior to the operation until hospital discharge.
The placebo capsule matching the active study drug will be given daily from 5 days prior to the operation until hospital discharge.
- Incidence of postoperative urinary retention [ Time Frame: participants will be followed for the duration of the hospital stay, an expected average of 5 days ]
Post operative urinary retention (POUR) will be defined as any of the following:
1) Estimated post-void residual (PVR) volume of urine greater than or equal to 300 mL; 2) Estimated retention urine volume of greater than or equal to 500 mL in patients unable to void; 3) Patients experiencing discomfort or distension and unable to void with lesser residual urine volume than 500 ml.
- Duration of postoperative urinary retention [ Time Frame: participants will be followed for the duration of the hospital stay, an expected average of 5 days ]The neurosurgical team will decide if an indwelling urinary catheter will be used. Time of indwelling catheter removal after surgery will serve as time zero for beginning calculation of postoperative urinary retention duration if the patient later requires in and out straight catheterization. For patients without an indwelling catheter, the time patients leave the operating room will serve as time zero. Urinary retention will be considered resolved after two consecutive post-void residual urine scans have demonstrated less than 300 ml residual urine volume in a patient spontaneously voiding.
