Chronic Interstitial Cystitis
Persistently inflammed lesion of the bladder wall, usually accompanied by urinary frequency, pain, nocturia, and a distended bladder.
Circumcise
Circular cutting around the genitals to remove the prepuce of foreskin.
Condyloma
Infectious tumor-like growth caused by the human papilloma virus, with a branding connective tissue core and epithelial covering that occurs on the skin and mucous membranes of the perianal region and external genitalia.
Cystitis
Inflammation of the urinary bladder
Cystitis Cystica
Inflammation of the bladder characterized by the formation of multiple cysts.
Cystocele
Herniation of the bladder into the vagina.
Cystostomy
Formation of an opening through the abdominal wall into the bladder.
Cystotomy
Surgical incision into the urninary bladder or gallbladder
Dysuria
Pain upon urination.
Epididymis
Coiled tube on the back of the testis that is the site of sperm maturation and storage and where spermatozoa are propelled into the vas deferens toward the ejaculatory duct by contraction of smooth muscle.
Epididymo-orchitis
Inflammation of the testes and epididymis.
Epispadias
Male anomaly in which the urethral opening is abnormally located on the dorsum of the penis, appearing as a groove with no upper urethral wall covering.
Extrophy of Bladder
Congenital anomaly occurring when the bladder everts itself, or turns inside out, through an absent part of the lower abdominal and anterior bladder walls with incomplete closure of the pubic bone.
Foley Catheter
Temporary indwelling urethral catheter held in place in the bladder by an inflated balloon containing fluid or air.
Hematospermia
Blood in the seminal fluid, often caused by inflammation of the prostate or seminal vesicles, or prostate cancer.
Hematuria
Blood in urine, which may present as gross visible blood or as the presence of red blood cells visible only under a microscope.
Horseshoe Kidney
Congenital anomaly in which the kidneys are fused together at the lower end during fetal development, resulting in one large, horseshoe shaped kidney.
Hydronephrosis
Distention of the kidney caused by an accumulation of urine that cannot flow out due to an obstruction that may be caused by conditions such as kidney stones or vesicoureteral reflux.
Hydroureter
Abnormal enlargement or distension of the ureter with water or urine caused by an obstruction.
Hyperplasia
Abnormal proliferation in the number of normal cells in regular tissue arrangement.
Hypospadias
Fairly common birth defect in males in which the meatus is abnormally positioned on the underside of the penile shaft or in the perineum requiring early surgical correction.
Incontinence
Involuntary escape of urine.
Impotence
Psychosexual or organic dysfunction in which there is partial or complete failure to attain or maintain erection until completion of the sexual act.
Lithotripsy
Destruction of calcified substances in the gallbladder or urinary system by smashing the concretion into small particles to be washed out.
Lumen
The space within an artery, vein, intestine, or tube.
Meatus
Opening or passage into the body.
Nephrostomy
Placement of a stent, tube, or catheter that forms a passage from the exterior of the body into the renal pelvis or calyx, often drainage of urine or an abscess, for exploration, or calculus extraction.
Neurogenic Bladder
Dysfunctional bladder due to a central or peripheral nervous system lesion that may result in incontinence, residual urine retention, infection, stones, and renal failure.
Nocturnal Enuresis
Bed wetting
Oligospemia
Insufficient production of sperm in semen, a common factor in male infertility.
Orchiectomy
Surgical removal of one or both testicles via a scrotal or groin incision, indicated in cases of cancer, traumatic injury, and sex reassignment surgery.
Patency
State of a tube-like structure or conduit being open and unobstructed.
Perineal
Pertaining to the pelvic floor area between the thighs; the diamond shaped area bordered by the pubic symphysis in front, the ischial tuberosities on the sides and the coccyx in the back.
Peritoneum
Strong, continuous membrane that forms the lining of the abdominal and pelvic cavity.
Peyronie's Disease
Development of fibrotic hardened tissue or plaque in the cavernosal sheaths in the penis.
Phimosis
Condition in which the foreskin is contracted and cannot be drawn back behind the glans penis.
Priapism
Persistent, painful erection lasting more than four hours and unrelated to sexual stimulation, causing pain and tenderness.
Prepuce
Fold of penile skin covering the glans
Prolapse
Falling, sliding, or sinking of an organ from its normal location in the body.
Prostate
Male gland surrounding the bladder neck and urethra that secretes a substance into the seminal fluid.
Retroperitoneal
Located behind the peritoneum
Scrotum
Skin pouch that holds the testes and supporting reproductive structures.
Seminal Vesicles
Paired glands located at the base of the bladder in males that release the majority of fluid into semen through the ducts that join with the vas deferens forming the ejaculatory duct.
Skene's Gland
Paraurethral ducts that drain a group of the female urethral glands into the vestibule.
Spermatic Cord
Structure of the male reproductive organs that consists of the ductus deferens, testicular artery, nerves and veins that drain the testes.
Stricture
Narrowing of an anatomical structure
Testes
Male gonadal paired glands located in the scrotum that secrete testosterone and contain the seminiferous tubules where sperm is produced.
Torsion of Testis
Twisting, turning or rotation of the testicle upon itself.
Trigone
Triangular, smooth area of mucous membrane at the base of the bladder, located between the ureteric openings in back and the urethral opening in front.
Tunica Vaginalis
Serous membrane that partially covers the testes formed by an outpocketing of the peritoneum when the testes descend.
Urachus
Embryonic tube connecting the urinary bladder to the umbilicus during development of the fetus that normally closes before birth, generally in the fourth or fifth month of gestation.
Urethra
Small tube lined with mucous membrane that leads from the bladder to the exterior of the body.

Vesical fistula
Abnormal communication between the bladder and another structure.
Vesicoureteral reflux
Urine passage from the bladder back up into the ureter and kidneys that can lead to bacterial infection and an increase in hydrostatic pressure, causing kidney damage.
