Erler-Zimmer GmbH & Co. KG 3D model of nodular hyperplasia of the prostate:
- Model: MP2108
- Clinical History:
A 63-year-old man presented to the emergency department with acute abdominal pain. He had been unable to urinate for 5 days. Further investigation revealed that he had been suffering from increased urinary frequency, double urination, urinary hesitancy, nocturia, and a weak urinary stream for 2 years. Abdominal examination revealed an inflamed and enlarged bladder, and digital rectal examination revealed an enlarged prostate gland. Bedside bladder scan revealed a bladder volume of more than 1 liter. Blood tests revealed severe acute renal failure. He was diagnosed with acute renal failure due to acute urinary retention. There were multiple attempts to catheterize the patient through the urethra and rectum. Total prostatectomy was performed, and he made a full recovery. - Pathology:
The specimen is an enlarged prostate gland that has been cut transversely to expose the external and internal surfaces. The cut surface contains numerous nodules ranging in diameter from 2 to 10 mm. This is an example of benign prostatic hyperplasia (BPH). - Note:
Benign prostatic hyperplasia (BPH) or nodular hyperplasia of the prostate is a common disease in older men. BPH is caused by nodular hyperplasia of prostatic stromal and glandular epithelial cells, primarily in the periurethral region of the prostate. The hyperplasia is the result of the accumulation of senescent cells due to impaired cell death and cell proliferation, stimulated by androgens, particularly dihydrotestosterone. Disproportionate enlargement of the median lobe is a characteristic feature of nodular hyperplasia of the prostate. The protruding median lobe can occlude the internal opening of the bladder during voiding.
