The transurethral incision of the prostate, or TUIP, is similar to a TURP. The TUIP is considered an open operation, because incisions are involved. In this relatively simple procedure, a pair of incisions are made on the sides of the bladder neck that closes the bladder off from the urethra. The surgeon does not remove any of the prostate tissue that causes the blockage. If the incision is deep enough, the prostate will spring open, and many cases will not subsequently require prostatic resection.
Often, the typical problems of BPH, such as getting up at night and a reduced urine flow, are improved by a TUIP. The procedure is quicker than a TURP, it causes less blood loss and less risk of retrograde ejaculation (about 15 percent), and it has a 1 percent risk of either incontinence or impotence. This procedure is available for widespread clinical use and is, according to Dr. Joseph E. Oesterling, "The most grossly underused treatment for BPH."
Concerns In some patients, symptoms recur within a few months. In others, relief lasts for several years. The TUIP is not recommended for very enlarged prostates. Of the men undergoing a TUIP, 5 to 10 percent will require a second operation.
