Introduction: Bladder outlet obstruction is one of the commonest causes of LUTS. Most common cause of BOO in men is BPH. Other common causes are bladder stones and bladder cancer. There is also increased incidence of BOO in younger age group too. In younger age group urethral stricture is commonly seen. Aims and objectives: To study various etiology and clinical presentations and management of bladder outlet obstruction according to standard surgical guidelines using either minimally invasive or conventional means. Materials and Methods: A total of 100 cases were admitted in Deccan College of Medical Sciences and Owaisi Hospital and Research Centre, Hyderabad, India from 1st September 2011 to 31th August 2013 with objective evidence of bladder outlet obstruction and study was conducted accordingly. Discussion: This study is a prospective observational study. The most common cause of BOO was evaluated and was treated according to standard line of treatment and follow up done accordingly. Conclusion: Bladder outlet obstruction is a clinical entity of diverse etiology and is a potentially curable illness if diagnosis is made early and treated according to the standard guideline of management. In patients not fit for surgery obstruction can be relieved by catheterization and treatment can be planned once patient is fit for definitive procedure. A further population based study is needed to identify the exact prevalence of BOO in different age groups and effectiveness of available modality and long term complications.
