This operation, procedure and side-effects is very similar to the TURP and may be more suitable for men with only a slightly enlarged prostate. The difference being that rather than trimming off any prostate tissue, one or 2 small cuts are made where the bladder joins the urethra. This allows the enlarged prostate tissue to spring apart and so stops the enlarged tissue squeezing the urethra as much. The procedure takes approximately 20 minutes. This means that passing urine should be easier. However, if symptoms remain the same or come back after the TUIP then a TURP may be necessary.
