THE PROSTATE GLAND IN OLD AGE

Age-related changes in the innervation of the prostate gland

The adult prostate gland grows and develops under hormonal control while its physiological functions are controlled by the autonomic nervous system. The prostate gland receives sympathetic input via the hypogastric nerve and parasympathetic input via the pelvic nerve. In addition, the hypogastric and pelvic nerves also provide sensory inputs to the gland. This review provides a summary of the i...

The age old question: who benefits from prostate cancer treatment?

Active surveillance and watchful waiting are potential alternatives to delay or avoid the need for treatment in carefully selected patients. The key issue is determining which patients are appropriate for conservative management. Although these approaches are often targeted toward elderly men, such men are more likely to be diagnosed with high-risk disease. A recent study by Scosyrev et al. [2]...

The Prostate Gland

Comparison of Transabdominal and Transrectal Ultrasonography of the Prostate Gland in Dogs

Objective- To compare transabdominal (TA) and transrectal (TR) ultrasonography of the prostate gland. Design- Experimental study. Animals- 10 intact male dogs that required euthanasia for reasons other than prostatic disease. Procedures- Prostatic length (L), width (W) and height (H) were measured in T A (L1, W1 and H1) and TR (L2 and H2...

Visualizing the Prostate Gland by MR Imaging in Young and Old Mice

PURPOSE Prostate imaging requires optimization in young and old mouse models. We tested which MR sequences and field strengths best depict the prostate gland in young and old mice; and, whether prostate MR signal, size, and architecture change with age. TECHNIQUE Magnetic resonance imaging (MRI) of the prostate of young (2 months) and old (18 months) male nude mice (n = 6) was performed at 4....
