Urinary retention is complex and may present in various ways as a result of a myriad of pathologic processes. Acute retention of urine is defined as a painful, palpable or percussable bladder, when the patient is unable to pass any urine. AUR may be further subdivided into precipitated or spontaneous retention. Aim of treatment is to restore the ability to void spontaneously as soon as possible, to avoid catheter–related complications and improve patient quality of life. Trial without Catheter (TWOC) is now considered for most patients. It involves catheter removal allowing the patient to successfully void which enables patients to return home without the potential morbidities associated with an in situ catheter. TWOC also allows surgery to be delayed to an elective setting or may prevent the need for surgery. This study puts in a sincere effort to identify predictors of successful trial without catheter after an episode of acute urinary retention
