Short answers, pulled from the story.
Urology is the branch of medicine focused on surgical and medical diseases of the urinary system and the male reproductive organs. Organs under its domain include the kidneys, adrenal glands, ureters, urinary bladder, urethra, testes, epididymides, vasa deferentia, seminal vesicles, prostate, and penis.
Urology is one of the most competitive surgical specialties, with new urologists comprising less than 1.5% of United States medical-school graduates each year. In the 2022 match cycle, only 65.6% of US seniors matched into urology residency programs.
The American Urological Association recognizes seven subspecialties after residency: oncology, calculi, female urology, infertility, pediatrics, transplant (renal), and neurourology. Many urologists pursue additional fellowship training lasting 12 to 36 months in one of these areas.
Endourology is the branch of urology that manipulates the urinary tract using small cameras and instruments inserted through natural openings, primarily the urethra, rather than cutting through the abdominal wall. Procedures include holmium laser enucleation of the prostate (HoLEP), laser lithotripsy for kidney and ureteral stones, and flexible ureteroscopy, many of which can be performed as outpatient interventions without general anesthesia.
Neurourology addresses urinary dysfunction caused by conditions such as stroke, multiple sclerosis, Parkinson's disease, and spinal cord injury. These can produce urinary incontinence, detrusor overactivity, urinary retention, and detrusor sphincter dyssynergia, treated through approaches including sacral neuromodulation, botulinum toxin injections into the bladder wall, and anticholinergic drugs.
In 2001, Ethiopia had only five qualified urologists, all trained abroad, with all urological care handled by general surgeons at Tikur Anbessa Tertiary Hospital. A specialist curriculum for general surgeons launched in 2009, followed by a five-year residency for general practitioners beginning in 2010. Between 2009 and 2019, Tikur Anbessa trained a total of 23 urologists, and as of 2020, all graduates were working in different parts of the country.
