File:IPLab2Hyperplasia9.jpg|This kidney was removed from another autopsy patient who had prostatic hyperplasia resulting in marked urinary retention and back-flow of urine from the bladder into the ureters and renal pelvis. The increased pressure inside the renal pelvis resulted in dilation of the renal pelvis (1) and pressure atrophy of the cortex (2). This change in the kidney is called hydronephrosis.

== Study Questions ==
* <spoiler text="What is the name of the condition in this man's prostate?">This is an example of nodular hyperplasia which is commonly referred to as benign prostatic hyperplasia (BPH). The term BPH is redundant since hyperplasia is always benign.</spoiler>
* <spoiler text="In what anatomical region of the prostate is nodular hyperplasia most prevalent?">Nodules are most common in the inner peri-urethral region; thus, urethral obstruction is an early and common clinical sign.</spoiler>
* <spoiler text="In what region of the prostate does prostatic adenocarcinoma usually originate?">Prostatic adenocarcinoma usually arises in the peripheral zone of the gland, usually in a posterior location. Adenocarcinoma nodules are usually palpable by rectal examination.</spoiler>
* <spoiler text="What is the age-specific incidence of nodular hyperplasia in males?">The incidence of nodular hyperplasia is:
20% in men 40 years of age
30% in men 50 years of age
70% in men 60 years of age
90% in men 70 years of age</spoiler>
* <spoiler text="Does nodular hyperplasia predispose to adenocarcinoma?">No.</spoiler>
* <spoiler text="What other conditions can be associated with or result from nodular hyperplasia of the prostate?">Urinary retention, cystitis, bladder distention, hypertrophy, trabeculation, diverticulum formation, renal infections, and hydronephrosis.</spoiler>
