Hi. My grandfather faced urinal retention problem due to enlarged prostate and undergone TURP surgery in 2012. Again after two and half years that is on November 2015 he faced same problem. Unable to urinate and hence consulted the surgeon. He prescribed few medicines and asked us to do ultrasound scan of abdomen and also asked us take MRI. Later doctor suggested us to follow the medications incase if the same problem occurs he said surgery has to be done again. For three years my Grandfather was normal. Now again today 19th November 2018 he was not able to urinate so we have to put catheter to him and consulted the same surgeon. He said prostate has grown big and surgery has to be done and did ultrasound where the prostate size was 4.8*6.2*4.8 and 75 cc. Doctor prescribed few medicines and telling second surgery is required. Right now my grandfather is having catheter and through that only he is emptying urine. Please suggest best options. Is it ok to do the TURP operation again for second time.
