Immediate or delayed trial without catheter in acute urinary retention in males: A systematic review.

Objective: To compare the success of establishing spontaneous micturition following immediate trial without catheter (TWOC) to delayed TWOC in males catheterized for acute urinary retention.

Materials And Methods: In this systematic review, we included studies reporting success rates of immediate TWOC or delayed TWOC (≤30 days) among males ≥18 years of age catheterized for acute urinary retention. We excluded studies on suprapubic catheterization, postoperative/perioperative catheterization and urinary retention related to trauma.
