Urinary retention is the most common urological emergency and more than 95% of cases occur in men. Acute urinary retention (AUR) is defined as the sudden inability to pass any urine voluntarily associated with a painful, palpable or percussable bladder. In chronic urinary retention (CUR) there is a non-painful bladder, which remains palpable or percussable after the man has passed urine, with a post-void residual volume > 300 ml. In acute on chronic urinary retention no urine can be voluntarily passed but the condition is relatively painless and the residual volume on catheterisation is > 1.5 litres.

Androgens play a crucial role in bone, muscle and fat metabolism, erythropoiesis and cognitive health. In men aged 40-79 years the incidence of biochemical deficiency and symptomatic hypogonadism is 2.1-5.7%. Decreased libido or reduced frequency and quality of erections, fatigue, irritability, infertility or a diminished feeling of wellbeing may be presenting complaints. However, a significant proportion of men with androgen deficiency will be identified when they present for unrelated concerns.

The prostate specific antigen (PSA) test clearly provides the opportunity for clinically relevant prostate cancer to be detected at a stage when treatment options are greater and outcomes may be improved. In addition, a raised PSA may often indicate benign prostatic enlargement, and this may provide an opportunity for treatment of this condition before complications develop. However, in some patients the PSA test may lead to investigations which can identify clinically insignificant cancers which would not have become evident in a man’s lifetime.

Advanced prostate cancer remains an incurable and lethal disease. Innovation continues to provide new hope for patients with advanced disease, with improved survival while maintaining quality of life. As patients live longer with increasing treatment options, education of all healthcare professionals involved in their care is crucial in ensuring holistic care for this complex disease.

A suspicion of a diagnosis of prostate cancer is usually based on either induration or nodularity of the prostate on digital rectal examination or, more commonly, a rise in serum prostate specific antigen (PSA) level. The usual cut-off point for PSA is taken as 4 ng/ml, but in men below 65 a value of more than 2.5 ng/ml should raise suspicion. The Gleason grading of any cancer identified is an important part of the decision-making process concerning the need for active treatment, as opposed to surveillance alone. Gleason pattern 6 cancers are regarded as low risk, Gleason 7 intermediate risk and 8-10 high risk. [With external links to the current evidence base]
