Prostatectomy

A prostatectomy is the surgical removal of all or part of the prostate gland. Enlargement of the prostate, commonly through benign prostatic hyperplasia (BPH), but sometimes through abnormalities such as a tumour, or from other causes, can restrict the normal flow of urine along the urethra, causing discomfort and difficulty voiding. Early preventive medical intervention with medications such as finasteride may forestall urinary restriction, making surgery unnecessary. Once a significant urinary restriction develops, however, it increases risks of obstructive uropathy, and even poses serious kidney damage from obstructive nephropathy if left untreated.
