What is Urology?
The surgical specialty that mainly concentrates on the diseases of the female and male urinary tracts along with male reproductive organs is known as urology. Medical professionals specializing in the field of urology are called urologists and are trained to diagnose, treat, and manage patients with urological disorders. The organs covered by urology include the kidneys, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate and penis). Both Urologists and General Surgeons operate on the adrenal glands.
In men, the urinary system overlaps with the reproductive system, and in women the urinary tract opens into the vulva. In both sexes, the urinary and reproductive tracts are close together, and disorders of one often affect the other. Urology combines management of medical (i.e. non-surgical) problems such as urinary tract infections and benign prostatic hyperplasia, as well as surgical problems such as the surgical management of cancers, the correction of congenital abnormalities, and correcting stress incontinence. Urology is closely related to, and in some cases overlaps with, the medical fields of oncology, nephrology, gynecology, andrology, pediatric surgery, gastroenterology, and endocrinology.
I can’t imagine the direction of the wind, but I can adjust my sails to alway search my destination.
When it’s dark enough, you can see the stars.
Once you choose hope, anything’s possible. Hope never abandons you, you abandon it.
The most beautiful people we have known are those who have known defeat, known suffering, known struggle, known loss, and have found their way out of the depths. These persons have an appreciation, a sensitivity, and an understanding of life that fills them with compassion, gentleness, and a deep loving concern. Beautiful people do not just happen.
Dear GOD, if today I lose my hope please remind me that your plans are better than my Dream.....
Endourology - it is the branch of urology that deals with minimally invasive surgical procedures. As opposed to open surgery, endourology is performed using small cameras and instruments inserted into the urinary tract. Traditionally, transurethral surgery has been the cornerstone of endourology. Via the urethra, the complete urinary tract can be reached, enabling prostate surgery, surgery of tumors of the urothelium, stone surgery, and simple urethral and ureteral procedures.
Laparoscopy - it is a rapidly evolving branch of Urology and has replaced some open surgical procedures. Robotic assisted surgery of the prostate, kidney, and ureter has been expanding this field.
Urologic Oncology - its concerns the surgical treatment of malignant genitourinary diseases such as cancer of the prostate, adrenal glands, bladder, kidneys, ureters, testicles and penis. The medical treatment of advanced genitourinary cancer is managed by either a Urologist or an Oncologist depending on the cancer.
Neurourology - it concerns nervous system control of the genitourinary system, and of conditions causing abnormal urination. Neurological diseases and disorders such as multiple sclerosis, Parkinson’s disease, and spinal cord injury can disrupt the lower urinary tract and result in conditions such as urinary incontinence, detrusor overactivity, urinary retention, and detrusor sphincter dyssynergia. Urodynamic studies play an important diagnostic role in neurourology. Therapy for nervous system disorders includes clean intermittent self-catheterization of the bladder, anticholinergic drugs, injection of Botulinum toxin into the bladder wall and advanced and less commonly used therapies such as sacral neuromodulation.
Less marked neurological abnormalities can cause urological disorders as well - for example, abnormalities of the sensory nervous system are thought by many researchers to play a role in disorders of painful or frequent urination (e.g. painful bladder syndrome, formerly known as interstitial cystitis).
Pediatric urology - it concerns urologic disorders in children. Such disorders include cryptorchism (undescended testes), congenital abnormalities of the genito-urinary tract, enuresis, underdeveloped genitalia (due to delayed growth or delayed puberty, often an endocrinological problem), and vesicoureteral reflux.
Andrology - it focuses on the male reproductive system. It is mainly concerned with male infertility, erectile dysfunction and ejaculatory disorders. Since male sexuality is largely controlled by hormones, andrology overlaps with endocrinology. Surgery in this field includes fertilization procedures, vasectomy reversals, and the implantation of penile prostheses. Vasectomies may also be included here although most Urologists perform this procedure.
Reconstructive urology reestablishes functionality of the genito-urinary tract. Strictures of the urethra or the ureter often require reconstructive surgery. Another frequent procedure is the reconstruction of the urinary bladder from small bowel in conjunction with cancer surgery. Cosmetic surgery such as penis enlargement is rarely done in urology.
Female urology - it is a branch dealing with overactive bladder, pelvic organ prolapse, and urinary incontinence. Thorough knowledge of the female pelvic floor together with urodynamic skills is necessary to diagnose and treat these disorders. Depending on the cause of the individual problem a medical or surgical treatment can be the solution.
