可见前列腺显著增大，不仅是两侧小叶，中叶也肥大。这导致了尿道前列腺部阻塞，引起慢性尿道梗阻。结果，每次排尿时为了克服阻力，膀胱代偿性肥大，膀胱表面形成小梁。另外，在膀胱内还有棕黄*色的结石。
The markedly enlarged prostate seen here has not only large lateral lobes, but a very large median lobe as well that obstructs the prostatic urethra and led to chronic urinary tract obstruction. As a result, the bladder became both enlarged and hypertrophied as it had to work against the obstruction with every episode of urination. That is why the surface of the bladder appears trabeculated. Note also that a yellowish-brown calculus formed in the bladder.
