Prostatitis: Infiltration of inflammatory cells into the parenchyma of PROSTATE. The subtypes are classified by their varied laboratory analysis, clinical presentation and response to treatment.Pelvic Pain: Pain in the pelvic region of genital and non-genital origin and of organic or psychogenic etiology. Frequent causes of pain are distension or contraction of hollow viscera, rapid stretching of the capsule of a solid organ, chemical irritation, tissue ischemia, and neuritis secondary to inflammatory, neoplastic, or fibrotic processes in adjacent organs. (Kase, Weingold & Gershenson: Principles and Practice of Clinical Gynecology, 2d ed, pp479-508)Prostate: A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.Prostatic Diseases: Pathological processes involving the PROSTATE or its component tissues.Chronic Disease: Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care. (Dictionary of Health Services Management, 2d ed)Prostatein: A secreted prostate-specific protein which can bind non-polar steroids, cholesterol and a group of small, proline-rich peptides. The protein is specifically found in RATS and comprises three distinct secretoglobin-related subunits referred to as prostatic steroid-binding protein C1, C2 and C3.Prostatic Hyperplasia: Increase in constituent cells in the PROSTATE, leading to enlargement of the organ (hypertrophy) and adverse impact on the lower urinary tract function. This can be caused by increased rate of cell proliferation, reduced rate of cell death, or both.Phellodendron: A plant genus of the family RUTACEAE. Members contain BERBERINE, indolopyridoquinazoline and other ALKALOIDS and limonoids.Mycoplasmatales Infections: Infections with bacteria of the order MYCOPLASMATALES.Gardenia: A plant genus of the family RUBIACEAE. Members contain genepin, from which geniposide is obtained for use as a crosslinking agent in ADHESIVES, and 3-caffeoyl-4-sinapoylquinic acid.Urethritis: Inflammation involving the URETHRA. Similar to CYSTITIS, clinical symptoms range from vague discomfort to painful urination (DYSURIA), urethral discharge, or both.Polygonum: A plant genus of the family POLYGONACEAE that is an ingredient of Shou-Wu-Pian, a Chinese herbal preparation (DRUGS, CHINESE HERBAL). The common name of black bindweed also refers to TAMUS or Fallopia (use POLYGONACEAE).Epididymitis: Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.Pyelonephritis: Inflammation of the KIDNEY involving the renal parenchyma (the NEPHRONS); KIDNEY PELVIS; and KIDNEY CALICES. It is characterized by ABDOMINAL PAIN; FEVER; NAUSEA; VOMITING; and occasionally DIARRHEA.
