Azoospermia

Chemotherapy

The use of drugs to treat cancer.

Chordee

A deformity of the penis which results in a bending on erection.

Cystitis

Inflammation of the internal lining of the bladder.

Circumcision

Surgical removal of the foreskin, usually performed for phimosis.

CT

Computerised tomography; a form of X-ray where slices are taken through the body to produce images at different levels.

Cystectomy

Surgical removal of the bladder, usually for invasive cancer.

Cystocele

Prolapse of the bladder into the vagina.

Cystogram

An X-ray of the bladder where dye is inserted into the bladder using a catheter.

Cystoscopy

Inspection of the bladder using a telescope (either flexible or rigid) with an attached light source to illuminate the interior of the bladder.

Cytology

The study of individual cells, usually in the urine, to identify malignancy or other disorders.

Dilatation

Stretching or widening of an opening, usually the urethra or neck of the bladder.

Diverticulum

An abnormal pouch leading off the cavity of a hollow organ; most commonly seen in the bladder.

DRE

Digital rectal examination; usually to feel the prostate gland.

Dysuria

Painful passage of urine.

Embolisation

Blocking the artery to an organ by introducing foam, coils or gel under X-ray control using a small catheter placed in the artery.

Enuresis

Incontinence of urine at night usually considered synonymous with bedwetting.

Epididymis

The sperm-carrying mechanism lying behind the testis which carries sperms from the testis to the vas deferens during ejaculation.

Epididymitis

Inflammation / infection of the epididymis, often involving the testis as well (epididymo-orchitis).

Erectile dysfunction

Impotence; the inability to obtain or maintain an erection sufficient for penetration and the satisfaction of both sexual partners.

ESWL

Extracorporeal shockwave lithotripsy; shockwaves generated in water, focussed and fired through the body to fragment stones in the kidney or ureter.

Extravasation

Leakage of urine or surgical irrigation fluid outside the urinary tract.

Exstrophy

A congenital condition where the bladder remains on the surface of the lower abdomen open to the outside.

Frequency

Passing urine too often, usually during the day.

Haematospermia

Blood in the semen during ejaculation.

Haematuria

Blood in the urine.

Hydrocele

An abnormal collection of fluid in the naturally-occurring sac which surrounds the testicle.

Hesitancy

Having to wait an abnormally long time for the flow of urine to start.

Immunotherapy

Involuntary leakage of urine.lating the natural immune response.

Incontinence

Involuntary leakage of urine

IVU

Intravenous urogram; an X-ray of the kidneys, ureters and bladder performed using an injection of dye into a vein in the arm.

Kidney

One of two paired organs (normally) which lie at the back of the abdomen, in front of the lower ribs, and filter the blood to produce urine.

Laser

Light amplification by the stimulated emission of radiation; an energy source for performing some types of urological surgery.

Laparoscope

A telescope with a light source and camera attached which is inserted into the abdominal cavity (through a small incision) to perform ‘keyhole’ surgery.

Lithotripsy

Wearing away of a stone; usually synonymous with ESWL.

Litholapaxy

Crushing of a stone, usually in the bladder, to reduce it to fragments small enough to be passed spontaneously or removed through an endoscope.

Lymphadenectomy

Surgical removal of lymph nodes to determine whether they are involved with cancer.

Metastasis

A secondary tumour (remote from the original cancer) which has arisen by spread through the blood, the lymph system or by direct invasion.

MRI

Magnetic resonance imaging; a means of producing cross-sectional images of the body to characterise tissues by the way the electrons in the tissue move in response to a strong magnetic field.

Nephron

The microscopic filtering unit in the kidney which filters water and waste products from the blood.

Nocturia

Abnormal passage of urine at night.

Phimosis

Tightness of the foreskin, either due to a scarring disease or as a result of a congenital abnormality.

Paraphimosis

Retraction of a tight foreskin which becomes “stuck” due to an inability to return it to its original position covering the head of the penis.

Polyuria

Over-production of urine, usually at night; often occurs in the elderly due to poor water handling ability with increasing age.

Prostate gland

A chestnut-sized organ lying at the bottom of the bladder which produces chemicals to nourish sperms and facilitate their transport to the female uterus.

Prostatitis

Infection or inflammation of the prostate gland.

Prosthesis

An artificial implant used to replace any part of the body (e.g. a testicle).
