The prostate surrounds the urethra just below the urinary bladder. On urination, urine passes out of the bladder through the urethra which goes through the prostate gland and into the penis. The weight of a normal prostate in a healthy adult male is approx. 15g. An enlarged prostate (Benign prostatic hyperplasia) is very common in older men. Symptoms include a weak urinary stream, having to urinate more frequently during the daytime and night time and dribbling of urine after urination. Medication may shrink an enlarged prostate and thus relieve symptoms. In some cases, however, a minimally invasive procedure is necessary to remove the enlarged part of the prostate (BPH). This is usually carried out through the urethra whereby the innermost core of the prostate is scraped away. Over the past few years many new and alternative surgical techniques (laser, microwave, cryotherapy) have been tested, however, the most tried and tested method - the gold standard - remains the ablation of the prostate through the urethra (Transurethral resection of the prostate, so called TUR-P).
