This is a very common condition in men, especially over the age of about 50 which can cause urinary symptoms of hesitancy (ie difficulty in getting the urine flow started), slow flow, frequency of urination, urgency and getting up at night to pass urine. Once prostate cancer has been excluded, usually by physical examinaton and blood tests, management ranges from behavioural modifications, medication through to operations. There are many different procedures designed to dis-obstruct the outlet of the bladder including transurethral resection of the prostate ("TURP") which can be done either in the conventional way or by newer techniques including using bipolar diathermy.
