Urology
Kidneys, ureters, bladder, prostate and the male reproductive tract: stones and the obstructed infected kidney that cannot wait, bladder cancer surveyed and resected through the urethra, and a specialty that reached keyhole surgery before almost anyone else.

Overview
What this specialty treats, and how it thinks.
Flow, obstruction and the tract that reached keyhole surgery first.
- Urology manages the urinary tract and the male reproductive organs: stones and the obstructed kidney, bladder and prostate cancers, retention and its causes, and the scrotal emergencies where hours decide organs.
- Its master rule is the one about pressure: an obstructed urinary system that becomes infected must be drained, and the obstructed infected kidney is one of surgery's true drop-everything emergencies.
- The specialty operates from inside as much as outside: cystoscopy, ureteroscopy and transurethral resection made it endoscopic decades before laparoscopy reached the abdomen.
- Its cancers teach oncology's whole spread of tempos: bladder cancer surveilled and resected repeatedly, prostate cancer managed across decades, and testicular cancer cured briskly in young men.

How patients arrive
Presentations
Loin pain with fever
“Colicky right loin pain radiating to the groin, now with rigors and a temperature of 38.9: CT shows a 7 mm stone in the ureter and a swollen kidney above it.”
- Stone pain alone is managed expectantly or electively; stone pain with fever is a different disease: infection above an obstruction, under pressure, seeding the bloodstream.
- The kidney's version of cholangitis follows the same law: antibiotics are cover, drainage is treatment, and the drain cannot wait for office hours.
- Two routes decompress: a retrograde ureteric stent from below, or a percutaneous nephrostomy from above, chosen by stability, anatomy and availability.
The man who cannot pass urine
“Twelve hours of inability to void, agonising suprapubic fullness, in a 74-year-old with years of hesitancy and nocturia he never mentioned.”
- Acute retention is treated first, explained second: the catheter is analgesia, diagnosis and treatment in one tube, and the residual volume gets written down.
- Ask what set it off: constipation, anticholinergics and opioids, infection, alcohol, or simply prostatic progression finally crossing the line.
- The kidneys report the chronicity: high-pressure chronic retention shows itself in creatinine and hydronephrosis, and its relief brings a diuresis that needs watching.
Painless visible haematuria
“A 68-year-old smoker reports two episodes of frank blood in the urine, painless, now clear again and hoping it was nothing.”
- Painless visible haematuria is bladder cancer until proven otherwise, and 'it went away' is the disease's favourite trick: intermittency reassures patients and should not reassure clinicians.
- The haematuria clinic answers it in one visit: flexible cystoscopy for the bladder, upper tract imaging for the kidneys and ureters, cytology as an adjunct.
- Smoking and occupational dye exposure are the classic risk factors: the urothelium is a field exposed to everything the kidneys filter.
The raised PSA
“A fit 66-year-old's health check returns a PSA of 8.2: no symptoms, a worried patient, and a decision tree with decades on its branches.”
- PSA is prostate-specific, not cancer-specific: infection, retention, instrumentation and size all raise it, so the number starts a pathway rather than making a diagnosis.
- MRI before biopsy is the modern sequence: the scan targets the biopsy and spares some men biopsy altogether.
- Grade and stage set the tempo: much low-grade disease is watched on active surveillance, deliberately and safely, while higher-grade disease meets surgery or radiotherapy.
The acute scrotum
“A 15-year-old woken by sudden severe left testicular pain, vomiting once: the testis rides high and tender, the reflex absent.”
- Torsion is first on the list until it is off the list, and it comes off the list in theatre, not on a scan report: the twisted cord is strangling the testis on a timer measured in hours.
- The classic story is short and sudden; epididymitis's story is slower with urinary symptoms; but overlap is common and the tie-break goes to exploration.
- Ultrasound is for the cases where the story has already made torsion unlikely: ordering it to 'confirm' a likely torsion spends the organ's minutes on a queue.
