Urologists perform well over a hundred distinct procedures spanning nearly every organ in the urinary tract and male reproductive system, from quick office-based tests that take minutes to complex cancer surgeries lasting several hours. The specialty covers diagnostic scoping of the bladder, kidney stone removal, prostate surgery, reconstructive work on the urethra, pediatric corrections, transplant operations, and a growing list of newer techniques. What surprises many people is the sheer range: a urologist might perform a vasectomy in the morning, a robotic prostatectomy after lunch, and an emergency surgery for testicular torsion that evening.
Diagnostic Procedures
Before any treatment begins, urologists rely on a set of diagnostic procedures to figure out what is going on inside the urinary tract. Cystoscopy is among the most common. A thin, flexible or rigid camera is passed through the urethra into the bladder, letting the surgeon visually inspect the lining for tumors, stones, structural abnormalities, or sources of bleeding. Flexible cystoscopy can be done in the office with local anesthetic and typically takes only a few minutes. It is one of the routine tasks that both physicians and advanced practice providers in urology offices perform regularly.1PubMed Central. Outpatient procedures by physician associates and nurse practitioners
Prostate biopsy is another staple diagnostic procedure. When blood tests or imaging raise concern about prostate cancer, the urologist takes small tissue samples, historically guided by transrectal ultrasound but increasingly performed via a transperineal approach, where the needle enters through the skin between the scrotum and rectum. The transperineal route has gained favor because it reduces infection risk compared to the rectal approach. MRI-targeted biopsies, which fuse imaging data to guide the needle toward suspicious areas, have further improved the accuracy of prostate cancer detection.2Urology Case Reports.

Urodynamic testing is less well known but plays a critical role for patients with urinary incontinence, difficulty emptying the bladder, or other lower-urinary-tract symptoms. These studies measure how the bladder and urethra store and release urine by tracking pressures and flow rates. AUA/SUFU guidelines position urodynamics as a tool clinicians should use after initial evaluation to guide treatment decisions rather than as a first-line screening test.3PubMed. Urodynamic studies in adults: AUA/SUFU guideline More advanced ambulatory urodynamics, which record bladder behavior during normal daily activities, are considered the most sensitive method for detecting involuntary bladder contractions when standard office-based testing comes back normal.4PubMed. Clinical usefulness of ambulatory urodynamics in the diagnosis and treatment of lower urinary tract dysfunction One thing worth knowing: urodynamic results can vary between sessions. A study of volunteers found that some parameters showed poor repeatability between two separate tests, even though detrusor overactivity and certain coordination problems were reliably reproduced.5PLOS ONE.

Kidney Stone Interventions
Kidney stones are one of the most common reasons people end up in a urologist’s office, and the field has several ways to deal with them depending on the stone’s size, location, and composition. The least invasive option is extracorporeal shockwave lithotripsy (SWL), which uses focused sound waves delivered from outside the body to break stones into fragments small enough to pass naturally. Patient selection matters: stone density, size, depth from the skin surface, and position within the urinary system all influence how well SWL works.6PubMed Central. Indications and contraindications for shock wave lithotripsy and how to improve outcomes
For stones that are too large or hard for shockwave treatment, urologists often turn to flexible ureteroscopy. A thin scope is threaded through the urethra, up through the bladder, and into the ureter or kidney, where a laser fragments the stone. No incision is needed. The alternative for larger or more complex stones is percutaneous nephrolithotomy (PCNL), where the surgeon makes a small puncture through the back directly into the kidney to remove the stone. A meta-analysis comparing these two approaches found that PCNL generally clears stones at a higher rate, but flexible ureteroscopy is safer, with less blood loss and fewer bleeding complications.7PubMed Central. Percutaneous nephrolithotomy versus flexible ureteroscopic lithotripsy in the treatment of upper urinary tract stones One cost-and-outcome analysis found stone clearance of about 89% for PCNL versus 47% for ureteroscopy when using a strict threshold, though the gap narrowed with a more lenient definition of clearance.8PubMed. Percutaneous nephrostolithotomy versus flexible ureteroscopy/holmium laser lithotripsy: cost and outcome analysis The choice between these procedures typically comes down to a conversation about stone burden, anatomy, and the tradeoff between the highest possible clearance rate and a lower complication risk.
Prostate Procedures for Benign Enlargement
An enlarged prostate causing urinary symptoms is one of the most frequent conditions urologists treat in older men. When medications stop working, several surgical options exist. Transurethral resection of the prostate (TURP) has been the traditional standard: the surgeon passes an instrument through the urethra and shaves away excess prostate tissue. It is effective but carries risks including bleeding, retrograde ejaculation, and, in a small percentage of cases, incontinence.
Newer procedures have expanded the menu considerably. Holmium laser enucleation of the prostate (HoLEP) uses a laser to core out the obstructing tissue, and a single-institution study comparing HoLEP, TURP, Rezūm (a water-vapor therapy), and UroLift (a mechanical implant that pins tissue out of the way) found that HoLEP produced the largest improvements in urinary flow rate and post-void residual urine volume. Both HoLEP and TURP significantly outperformed Rezūm and UroLift on those measures. Erectile dysfunction rates did not differ meaningfully across the four procedures, sitting at roughly five percent overall.9The Journal of Sexual Medicine. Sexual and Urinary Outcomes of HoLEP, TURP, Rezum and UroLift for BPH: A Single-Institution Retrospective Study Rezūm and UroLift appeal to men who want a minimally invasive option with quicker recovery and a lower chance of ejaculatory changes, but the tradeoff is that symptom relief tends to be more modest and retreatment rates are higher.
Cancer Surgery
Urologic oncology accounts for some of the most complex and high-stakes procedures urologists perform. The major operations include radical prostatectomy for prostate cancer, radical nephrectomy or partial nephrectomy for kidney cancer, radical cystectomy for bladder cancer, and retroperitoneal lymph node dissection for testicular cancer. A large analysis of nearly 40,000 urologic surgeries found that cystectomy carried the highest complication burden, with more than half of patients experiencing some form of complication, followed by nephrectomy and radical prostatectomy.10PubMed Central. Morbidity of urologic surgical procedures: an analysis of rates, risk factors, and outcomes
Robot-assisted surgery has transformed prostate cancer treatment in particular. Most radical prostatectomies in well-resourced settings are now performed robotically, with the surgeon operating through small incisions using magnified three-dimensional visualization and wristed instruments. The nerve-sparing technique, which aims to preserve the bundles of nerves running alongside the prostate that control erections, has become a major focus. A study tracking long-term outcomes found that patients who had both nerve bundles preserved achieved satisfactory erectile function at rates approaching 97%, compared to about 80% in those who had only one side spared.11Scientific Reports. Novel nerve-sparing robot-assisted radical prostatectomy with endopelvic fascia preservation and long-term outcomes for a single surgeon Whether a nerve-sparing approach is safe depends on each patient’s cancer risk profile, baseline erectile function, and individual anatomy, so the decision is tailored case by case.12PubMed Central. Nerve-sparing robot-assisted radical prostatectomy: Current perspectives
For bladder cancer that has not invaded the muscle wall, transurethral resection of a bladder tumor (TURBT) is the standard treatment. A scope is passed through the urethra and the tumor is shaved or scooped from the bladder lining. It is an endoscopic procedure without external incisions, though it often needs to be repeated and may be followed by instillation of medications directly into the bladder. Despite being less invasive than open surgery, TURBT still carries a complication rate of roughly 11% in large datasets.10PubMed Central.

Focal Therapy for Prostate Cancer
Between active surveillance and whole-gland surgery sits a growing category of focal therapies that treat only the cancerous portion of the prostate. The three most established options are cryotherapy (freezing), high-intensity focused ultrasound (HIFU, which uses concentrated sound waves to heat and destroy tissue), and irreversible electroporation (IRE, which kills cells using electrical pulses). A systematic review and meta-analysis found that all three are associated with good short-to-intermediate-term cancer control and functional results, though outcome reporting across studies is inconsistent and long-term data remain limited.13Prostate Cancer and Prostatic Diseases. Established focal therapy—HIFU, IRE, or cryotherapy—where are we now?—a systematic review and meta-analysis A separate meta-analysis pooling data on cancer-specific survival found rates above 96% across cryotherapy, HIFU, and IRE, with failure-free survival varying more widely between techniques.14PubMed. Cryoablation, high-intensity focused ultrasound, irreversible electroporation, and vascular-targeted photodynamic therapy for prostate cancer: a systemic review and meta-analysis These procedures are increasingly offered at specialized centers, but most guidelines still consider them investigational for routine use and recommend that patients be treated in the context of clinical trials or registries.
Minor Office-Based Procedures
A large share of what urologists do happens in the office without general anesthesia. Vasectomy is the most well-known example. The no-scalpel technique, which uses a small puncture rather than an incision to access the vas deferens, has become the preferred approach. Compared to the traditional method, the no-scalpel technique results in less bleeding, fewer infections, less pain, and a faster procedure, with no difference in contraceptive effectiveness.15PubMed Central. Scalpel versus no-scalpel incision for vasectomy16PubMed Central. Vasectomy surgical techniques: a systematic review
Other common office-based tasks include circumcision, urethral catheterization, hydrocele aspiration, and bladder instillation of medications (often chemotherapy or immunotherapy agents for bladder cancer). Hospital episode data from England identified urethral catheterization and bladder instillation among the ten most commonly performed urological procedures overall.17PubMed. The ‘top 10’ urological procedures: a study of hospital episodes statistics 1998-99 These procedures rarely make headlines, but in terms of sheer volume they dominate the workload.
Female Pelvic Medicine and Incontinence
Urology is not exclusively a men’s specialty. Female pelvic medicine and reconstructive surgery, sometimes practiced jointly with gynecologists, is a recognized urologic subspecialty. Urologists treat women with overactive bladder, stress urinary incontinence, and pelvic organ prolapse through a mix of surgical approaches.
Midurethral slings are one of the most common anti-incontinence procedures. A synthetic mesh tape is placed under the urethra to provide support during coughing, sneezing, or physical activity. When first-line treatments for overactive bladder fail, sacral neuromodulation offers another option. The procedure involves implanting a small device near the sacral nerves that sends mild electrical impulses to modulate bladder function. Improvement rates for urinary incontinence with pelvic floor neuromodulation techniques range from about 60% to 90%.18PubMed. Neuromodulation for the treatment of urinary incontinence Sacral neuromodulation has also been studied in women who previously had incontinence or prolapse surgery and continued to have refractory symptoms. Results in those patients appear similar to outcomes in women without a prior surgical history.19Female Pelvic Medicine & Reconstructive Surgery. Outcomes of Sacral Neuromodulation in Patients with Prior Surgical Treatment of Stress Urinary Incontinence and Pelvic Organ Prolapse
Pediatric Urology
Children present a distinct set of urologic problems, many of them congenital. The two most common surgical conditions in pediatric urology are hypospadias, where the urethral opening is on the underside of the penis rather than the tip, and undescended testes.
Hypospadias repair aims to reconstruct the urethra and straighten any curvature. Many surgeons favor operating before age one, but the evidence on timing is less settled than it appears. Longer follow-up reveals more complications over time, and whether mild distal hypospadias needs surgical correction at all during childhood has become a point of genuine debate in the field.20PubMed Central. Long-term outcomes of pediatric hypospadias and surgical intervention Fistula formation, wound breakdown, and narrowing of the new urethral opening are the most frequently reported complications.
For undescended testes, the standard procedure is orchidopexy, in which the testicle is surgically moved into the scrotum and secured in place. European guidelines endorse orchidopexy as the primary treatment, noting that hormonal therapy remains debated.21PubMed. Management of undescended testes: European Association of Urology/European Society for Paediatric Urology Guidelines Less common pediatric procedures include pyeloplasty to correct a blockage where the kidney drains into the ureter and nephrectomy for nonfunctional kidneys. Certification log data show that pediatric urologists perform these major operations relatively infrequently compared to the high-volume bread-and-butter cases.22Urology. Pediatric Urology What Can We Learn From Pediatric Urology Certification Logs?
Reconstructive Urology
Urethral stricture disease, where scar tissue narrows the urethra and obstructs urine flow, is one of the more challenging problems urologists manage. While short strictures can sometimes be treated with dilation or endoscopic incision, these approaches have high recurrence rates. Open urethroplasty, which surgically replaces or widens the narrowed segment, delivers more durable results.
Buccal mucosa grafts, harvested from the inner lining of the cheek, have become the workhorse tissue for urethroplasty. The tissue is hardy, easy to harvest, and heals well in the moist urethral environment. A systematic review evaluating more than 2,000 urethroplasties using buccal mucosa found success rates around 83% to 90% across different surgical techniques, with no meaningful difference between placing the graft on the top, bottom, or side of the urethra.23Frontiers in Urology. Buccal mucosa for use in urethral reconstruction: evolution of use over the last 30 years Research is also underway into lab-grown alternatives, including cultured buccal epithelial cells, though early results show them trailing traditional grafts in success rate.24PubMed.

Emergency Urological Procedures
Not all urologic surgery is elective. Certain conditions require intervention within hours or the consequences are irreversible. Testicular torsion, where the spermatic cord twists and cuts off blood supply to the testicle, is the most time-sensitive urologic emergency. The chance of saving the testicle drops sharply after about six hours. Diagnosis typically relies on Doppler ultrasound, and the treatment is surgical detorsion: untwisting the cord and fixing the testicle in place to prevent recurrence. Most surgeons also fix the opposite testicle at the same time.25PubMed Central. Non-traumatic urologic emergencies in men: a clinical review
Priapism, a prolonged and painful erection unrelated to sexual arousal, is another emergency. The ischemic (low-flow) form is the dangerous one, as stagnant blood deprives the erectile tissue of oxygen. First-line treatment involves aspirating blood from the penis and injecting a medication that constricts blood vessels. If that fails, a surgical shunt may be created to restore blood flow.26PubMed. Andrological emergencies in current emergency medicine: A narrative overview of clinical, psychological, and worldwide implications High-flow priapism, which results from an injury creating an abnormal connection between an artery and the erectile tissue, is less urgent and managed differently.
Kidney Transplant Surgery
It may surprise some people to learn that kidney transplantation often falls under the domain of urology in many countries. The operation involves retrieving the donor kidney (from a living or deceased donor), preparing it on a back table, and implanting it in the recipient’s pelvis. The surgeon connects the kidney’s blood vessels to the recipient’s iliac vessels and creates a new connection between the donor ureter and the recipient’s bladder.27PubMed Central. Surgical Strategies for Renal Transplantation: A Pictorial Essay Urologic complications after transplant, particularly ureteral stricture, are not rare and often require follow-up endoscopic or open surgical correction.28PubMed Central. Urological complications after renal transplantation – a single centre experience
Gender-Affirming Genital Surgery
Gender-affirming surgical procedures have become an increasingly recognized part of urologic practice, drawing heavily on the specialty’s reconstructive skill set. Vaginoplasty for transgender women and phalloplasty or metoidioplasty for transgender men are among the most technically demanding operations in the field. These procedures involve creating functional anatomy from existing tissue, and the complications that arise, particularly urethral strictures and fistulas after phalloplasty, call on the same reconstructive expertise urologists use for stricture disease in other contexts.29PubMed Central. Overview of surgical techniques in gender-affirming genital surgery A systematic review of variant approaches noted that urethral complications in masculinizing surgeries could be reduced by opting for a perineal urethrostomy rather than extending the urethra to the tip of the neophallus, and that vulvoplasty without vaginal canal creation in feminizing surgeries avoids the need for lifelong dilation.30PubMed.
