Urologists are physicians which have specialized in the field after completing their general degree in medicine. Upon successful completion of a residency program, many urologists choose to undergo further advanced training in a subspecialty area of expertise through a fellowship lasting an additional 12 to 36 months. Subspecialties may include: urologic surgery, urologic oncology and urologic oncological surgery, endourology and endourologic surgery,
urogynecology and urogynecologic surgery, reconstructive urologic surgery (a form of

Training
United States
As of 2022, there are 146
residency programs that offered 356 categorical positions.
Urology is one of the early match programs, with results given to applicants by early February (6 weeks before NRMP match). Applications are accepted starting Sep 1, with some programs accepting applications until early Jan.
It is a relatively competitive specialty to match into, with only 65.6% of US seniors matching in the 2022 match cycle.
The number of positions has grown from 278 in 2012 to 356 in 2022. Matching is significantly more difficult for IMGs and students who have a year or more off before residency - match rates were 27% and 55% respectively in 2012.
The medical school environment may also be a factor. A study in 2012 also showed after an analysis of match rates from schools between 2005 and 2009 that 20 schools sent more than 15 students into urology (1

Nepal
In Nepal, the formal urologist degree awarded is MCh (Magister Chirurgiae). This is a three years course post masters and includes thesis and a mandatory publication. This degree is awarded after completing MBBS (four and half year plus a one-year rotatory internship) and MS (Mastery of surgery) in general surgery (three years course). Till now two universities Tribhuvan University and Kathmandu University as well as two Autonomous institutes BP Koirala Institute of health sciences and National Academy of Medical Sciences (Bir Hospital) run the MCh Urology programme. This degree is equivalent to Clinical PhD and called as "Chikitsa Bidhyabaridhi" by Tribhuvan University (Government University) and is considered to be the highest degree among the surgical discipline degrees.
Ethiopia
In Ethiopia, in 2001, there were only five qualified urologists. All trained abroad, in countries like India, Tanzania and Hungary. Before this chapter all urology cases were managed by general surgeons. The only urological unit in the country was at Tikur Anbessa Tertiary Hospital. The services provided included
ESWL and endo-urology. The urology training program was started in 2009 with a curriculum for general surgeons which had a three-year training program. Up to 2019, six urologists have graduated by this program for general surgeons. The first residency program started accepting general practitioners in 2010 for a five-year program.
The first two years were trainings in general surgery, the next three years were dedicated urology training program, which included the same three-year training as of the general surgeons three year curriculum. It started with two residents who graduated in 2015 with a certificate in specialty of urology. Up to 2019, seventeen urologists have graduated from this five-year residency program. From the start these programs in 2009 up to 2019, a total of 23 urologists have been trained in Tikur Anbessa Tertioary Hospital. As of 2020, there were 26 trainees in the programme. All of the urologists who graduated from Tikur Anbessa Tertioary Hospital were as of 2020 working in different parts of the country.
Subdisciplines
As a medical discipline that involves the care of many organs and physiological systems, urology can be broken down into several subdisciplines. At many larger academic centers and university hospitals that excel in patient care and clinical research, urologists often specialize in a particular sub discipline.
Endourology
Endourology is the branch of urology that deals with the closed manipulation of the urinary tract. It has lately grown to include all minimally invasive urologic surgical procedures. As opposed to open surgery, endourology is performed using small cameras and instruments inserted into the urinary tract. Transurethral surgery has been the cornerstone of endourology. Most of the urinary tract can be reached via the urethra, enabling prostate surgery, surgery of tumors of the
urothelium, stone surgery, and simple urethral and ureteral procedures. Recently, the addition of laparoscopy and robotics has further subdivided this branch of urology.
Laparoscopy
Laparoscopy is a rapidly evolving branch of urology and has replaced some open surgical procedures.
Robot-assisted surgery of the prostate, kidney, and ureter has been expanding this field. Today, many prostatectomies in the United States are carried out by so-called robotic assistance. This has created controversy, however, as robotics greatly increase the cost of surgery and the benefit for the patient may or may not be proportional to the extra cost. Moreover, current (2011) market situation for robotic equipment is a de facto monopoly of one publicly held corporation
which further fuels the cost-effectiveness controversy.
Urologic oncology
Urologic oncology concerns the surgical treatment of malignant genitourinary diseases such as cancer of the prostate, adrenal glands, bladder, kidneys, ureters, testicles, and penis, as well as the skin and subcutaneous tissue and muscle and fascia of those areas (that particular subspecialty overlaps with dermatological oncology and related areas of oncology). The treatment of genitourinary cancer is managed by either a urologist or an oncologist, depending on the treatment type (surgical or medical). Most urologic oncologists in Western countries use minimally invasive techniques (laparoscopy or endourology, robotic-assisted surgery) to manage urologic cancers amenable to surgical management.

is the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men such as prostate cancer, male fertility problems, and surgery of the male reproductive system. It is the counterpart to gynaecology, which deals with medical issues that are specific to female health, especially reproductive and urologic health.
Reconstructive urology
Reconstructive urology is a highly specialized field of male urology that restores both structure and function to the genitourinary tract. Prostate procedures, full or partial hysterectomies, trauma (auto accidents, gunshot wounds, industrial accidents, straddle injuries, etc.), disease, obstructions, blockages (e.g., urethral strictures), and occasionally, childbirth, can necessitate reconstructive surgery. The urinary bladder, ureters (the tubes that lead from the kidneys to the urinary bladder) and genitalia are other examples of reconstructive urology.

. Many of these physicians also practice neurourology and reconstructive urology as mentioned above. Female urologists complete a 1–3-year fellowship after completion of a 5–6-year urology residency.
Thorough knowledge of the female pelvic floor together with intimate understanding of the physiology and pathology of voiding are necessary to diagnose and treat these disorders. Depending on the cause of the individual problem, a medical or surgical treatment can be the solution. Their field of practice heavily overlaps with that of urogynecologists, physicians in a sub-discipline of gynecology, who have done a three-year fellowship after a four-year OBGYN residency.
