Patients will be assessed for presence of voiding difficulty 6 hours post operatively, and patients who complain of voiding difficulty or inability to pass urine within 6 hours post operatively will be defined to have POUR, while a bladder scan will be performed will be performed . Patients with existing bladder volume of more than 400mls will be catheterised, while those with less than 400mls will be followed up with subsequent 2 hourly bladder scans, and catheterised should their bladder volume be beyond 400mls. Once discharged, patients will receive a phone call at 24 hours post discharge and scheduled to return for a follow up appointment 1 weeks later in the clinic where urinary symptoms will once again be assessed in both settings. The end points of incidence of POUR/catheterisation, length and cost of hospitalisation, rates of same day discharge, and patient satisfaction in both arms will be recorded and analysed. Patients will be analysed via an intention to treat basis, and patients who defaulted treatment (did not receive full 5 doses of medicine), did not turn up for surgery or lost to subsequent follow up post operatively will be taken into account, and reported and analysed accordingly.
