What is obstructive uropathy? 

  • Obstructive uropathy is blockage of urinary flow, which can affect one or both kidneys depending on the level of obstruction.
  • If only one kidney is affected, urinary output may be unchanged and serum creatinine can be normal.
  • When kidney function is affected, this is termed obstructive nephropathy.
  • Hydronephrosis refers to dilation of the renal pelvis and can be present with or without obstruction


What are some of the symptoms of obstructive uropathy? 

  • Flank pain
  • Fever
  • Lower urinary tract symptoms
  • Distended abdomen/palpable bladder
  • Inability to urinate
  • Enlarged or hard nodular prostate on rectal examination
  • Costovertebral angle tenderness


What are some of the causes of obstructive uropathy? How would these be classified?  

  • Luminal: stones, blood clot, sloughed papilla, tumour: renal, ureteric, or bladder
  • Mural: congenital or acquired stricture, neuromuscular dysfunction, schistosomiasis
  • Extra-mural: abdominal or pelvic mass/tumour, retroperitoneal fibrosis, or iatrogenic—eg post surgery


What are some of the RFs for urological surgery? 

  • BPH
  • Constipation
  • Medication (anticholinergic agents, narcotic analgesia, alpha receptor agonists)
  • Urolithiasis (ureteric calculi)
  • Spinal cord injury, Parkinson's disease, or multiple sclerosis
  • Malignancy


What investigations should be considered for obstructive uropathy? 

  • Bedside: urine dipstick, pregnancy for female, urine MC+S
  • Bloods: FBC, UE, CRP, PSA, CK, 
  • Others to consider: tumour markers (CEA, CA125))
  • Imaging: renal USS, CT (if there is hydronephrosis or hydroureter)


How would you manage obstructive uropathy? 

Upper Tract Obstruction

  • 1st: analgesia (diclofenac) and rehydration (IV fluids)
  • 2nd: ureteric stent or nephrostomy 
  • + alpha blockers e.g. tamsulosin
  • + Abx (if needed) e,g, gentamycin

Lower Tract Obstruction

  • Urethral or suprapubic catheter - Monitor weight, fluid balance, and u&e closely
  • After 2-3 days TWOC


What are renal stones and who do they affect? 

  • Renal stones (calculi) consist of crystal aggregates.
  • Stones form in collecting ducts and may be deposited anywhere from the renal pelvis to the urethra
  • 2-3% of the Western population. 
  • Males  <65yrs
  • They can form as both renal stones or ureteric stones 


Where do kidney stones commonly form?

  1. Pelviureteric junction
  2. Pelvic brim
  3. Vesicoureteric junction.


What types of kidney stones do you get? 

  • Calcium oxalate (75%).
  • Magnesium ammonium phosphate (struvite/triple phosphate; 15%).
  • Also: urate (5%), hydroxyapatite (5%), brushite, cystine (1%), mixed.


How do kidney stones present generally? 

  • Can be assymptomatic
  • Pain: ‘loin to groin’ (or genitals/inner thigh), with
  • Nausea/vomiting.
  • Cannot lie still 
  • Haematuria
  • Proteinuria
  • Sterile pyuria
  • Anuria


Depending on where the stone is obstructed, what type of symptoms do you get? 


  • Obstruction of kidney: felt in the loin, between rib 12 and lateral edge of lumbar muscles (like intercostal nerve irritation pain; not colicky, worsened by specific movements/pressure on a trigger spot). 
  • Obstruction of mid-ureter: mimic appendicitis/diverticulitis. 
  • Obstruction of lower ureter: sx of bladder irritability. Pain in scrotum, penile tip, or labia majora. 
  • Obstruction in bladder or urethra: pelvic pain, dysuria, strangury (desire but inability to void) ± interrupted flow.


How do the stones appear depending on their composition? 

  • Calcium (oxolate, phosphate)  - radio-opaque (spikey, smooth)
  • Magnesium ammonium phosphate (struvite) - stag horn calculi, radio-opaque
  • Urate - radio lucent


Why do kidney stones appear? 

  • Over-saturation of urine
  • High levels of purine in the blood (diet, haematological disorders)



What are some of the more specific reasons kidney stones appear? 

  • Diet: chocolate, tea, rhubarb, strawberries, nuts, and spinach (↑oxalate)
  • Season: variations in calcium and oxalate levels mediated by vitamin d synthesis 
  • Work: Water consumption (can they hydrate regularly)
  • Medications: diuretics, antacids, acetazolamide, corticosteroids, theophylline, aspirin, allopurinol, vitamin c and d, indinavir.


What are some of the predisposing factors to kidney stones? 

  • Recurrent UTIs (magnesium ammonium phosphate )
  • Metabolic abnormalities: 
    • Hypercalciuria/hypercalcaemia, hyperparathyroidism, neoplasia, sarcoidosis, hyperthyroidism, Addison’s, Cushing’s, lithium, vitamin d excess
    • Hyperuricosuria/↑plasma urate: on its own, or with gout
    • Cystinuria
    • Renal tubular acidosis 
  • Urinary tract abnormalities: PUJ obstruction, hydronephrosis, horseshoe kidney, vesicoureteric reflux, ureteral stricture
  • Foreign bodies: cathetar, stents 
  • FMH: ↑3-fold


What investigations are needed for diagnosis of kidney stones? 


  • Urine dipstick: Usually +ve for blood (90%) (non visible haematuria)mc&s
  • Bloods: fbc, u&e, Ca2+, po43−, glucose, bicarbonate, urate 
  • Urine pH; 24h urine for: calcium, oxalate, urate, citrate, sodium, creatinine; stone biochemistry (sieve urine & send stone)
  • Imaging:
    • GOLD STANDARD: CT KUB (high sensitivity and specificity)
    • AXR - sometimes used for initial assessment, - will only show radio opaque stones (80% but not all) 
    • USS (hydronephrosis)


What would the initial management be for kidney stones? 

  • IV fluid resuscitation
  • Analgesia: PR diclofenac 100mg 
  • If infection: Abx (eg piperacillin/tazobactam 4.5g/8h iv, or gentamicin) 
  • Anti emetic: ondansetron
  • ↑Fluid intake

Renal stones will pass spontaneously  if in the lower ureter or <5mm in diameter

Unless pregnant: remove stones via Ureteroscopy 


When should you admit a patient for kidney stones? 

  • Post-obstructive AKI
  • Uncontrollable pain from simple analgesics
  • Infected stone(s)
  • Large stones (>5mm)


What management is required for stones >5mm or pain not resolving? 

Medical expulsive therapy: 

  1. α‎-blockers (tamsulosin 0.4mg/d) - Most pass within 48h 
  2. ESWL (extracorporeal shockwave lithotripsy) - US waves shatter stone. Small stones: <2cm, performed via radiological guidance (either X-ray or USS). SE: renal injury, may also cause ↑bp and dm
  3. PCNL (Percutaneous nephrolithotomy): Keyhole surgery to remove stones, when large, multiple, or complex. For: large renal stones (including staghorn calculi).
  4. URS (Flexible uretero-renoscopy) - passing a scope retrograde up into the ureter, allowing stones to be fragmented through laser lithotripsy and fragments removed


How are kidney stones prevented generally and specifically? 


  • Drink plenty
  • Normal dietary Ca2+ intake


  • Calcium stones:  thiazide diuretic to ↓Ca2+ excretion.
  • Oxalate: ↓oxalate intake; pyridoxine
  • Struvite (phosphate mineral): treat infection 
  • Urate: allopurinol (100–300mg/24h po)
  • Cystine: vigorous hydration and urinary alkalinization 


How is obstructive nephropathy or significant infection secondary to renal stones managed? 

  • Retrograde stent insertion is the placement of a stent within the ureter, approaching from distal to proximal via cystoscopy 
  • Nephrostomy is a tube placed directly into the renal pelvis and collecting system, relieving the obstruction proximally 


What are the nice guidelines for urological referral (haematuria)?

  • Aged ≥45yrs with either:
    • Unexplained visible haematuria without urinary tract infection
    • Visible haematuria that persists or recurs after successful treatment of urinary tract infection
  • Aged 60yrs with have unexplained non‑visible haematuria and either dysuria or a raised white cell count on a blood test.


How is haematuria classified? 

  • Visible haematuria 
  • Non-visible haematuria (NVH): Blood is present in the urine on urinalysis, but not visible. Further categorised: 
    • Symptomatic non-visible haematuria (s-NVH): with associated symptoms,  e.g. suprapubic pain or renal colic.
    • Asymptomatic non-visible haematuria (a-NVH): + no associated symptoms.


What are some causes of haematuria? 

  • Infection, including pyelonephritis, cystitis, or prostatitis
  • Malignancy, including urothelial carcinoma or prostate adenocarcinoma

What are some of the possible complications of obstructive uropathy? 

  • Hyperkalaemia 
  • Metabolic acidosis
  • Post obstructive diuresis - lots of wee 
  • Na and Bicarb losing nephropathy - as kidneys under diuresis large amounts are lost from kidney. Replace bicarb
  • Infection 


What are some of the symptoms of BPH? 

  • LUTS: post micturition dribbling
    • Voiding symptoms: hesitancy, weak stream, terminal dribbling, or incomplete empyting

How do you investigate BPH: 

  • Bedside: urinalysis (to exclude UTI), DRE, post void bladder scan
  • Bloods: routine + PSA 
  • Imaging: USS, Urodynamic studies 


How do you treat BPH?

  • Conservative: avoid caffeine + alcohol, relax when voiding. Control urgency by practising distraction methods (eg breathing exercises). Bladder training.
  • Pharmacological: 
    1. Tamsulosin/ doxazosin. SE: drowsiness; depression; dizziness; ↓bp; dry mouth; ejaculatory failure; extra-pyramidal signs; nasal congestion; ↑weight
    2. 5α‎-reductase inhibitors: e.g.finasteride 5mg/d po 
  • Surgical
    • TURP: Transurethral resection of prostate (turp)
    • Transurethral incision of the prostate (TUIP): less destruction than turp, and less risk to sexual function, gives similar benefit. 
    • Retropubic prostatectomy: is an open operation (if prostate very large).
    • TULIP: Transurethral laser-induced prostatectomy
    • Robotic prostatectomy is gaining popularity as a less traumatic and minimally invasive treatment option.


What are the complications of BPH? What is TURP syndrome? 

High-pressure retention: chronic or acute-on-chronic urinary retention results in a post-renal kidney injury

TURP Syndrome: 

  • TURP with monopolar energy requires use of hypoosmolar irrigation during the procedure -> causes:
    • Fluid overload
    • Hyponatremia (must be corrected)
    • Glycine toxicity  as the fluid enters the circulation through the exposed venous beds.
    • Pt: confusion, nausea, agitation, or visual changes

Complications: TURP

T syndrome
U rethral stricture/UTI
R etrograde ejaculation
P erforation of the prostate

How would you manage acute urinary retention? 

  • Immediate urethral catheterisation
    • Monitored post-catheterisation for evidence of post-obstructive diuresis.
  • BPH: Tamsulosin
  • CSU for any evidence of infection and treat with antibiotics if needed. 
  • Review medications: for any potential contributing causes and treat any constipation if present.
  • TWOC: after 24-48hrs,  If the patient voids successfully, with a minimal residual volume, the TWOC is considered successful, whilst if the patient re-enters retention, the patient will require re-catheterisation.


What is post obstructive diuresis?

  • Can occur after resolution of the retention through catheterisation, the kidneys can often over-diurese due to the loss of their medullary concentration gradient, which can take time to re-equilibrate.
  • -> Worsening AKI 
    • Patients producing >200ml/hr urine output should have around 50% of their urine output replaced with IVI to avoid any worsening AKI.
  • Monitor UO in these patients over the following 24 hours post-catheterisation.

  • Locally advanced or metastatic bladder cancer – spreading beyond the bladder and distally
  • RF: smoking, age, exposure to aeromatic hydrocarbons (e.g. industrial dyes or rubbers), schistosomiasis infection (SCC), and previous radiation to the pelvis.


How would you investigate and manage bladder cancer? 

  • **Urgent cystoscopy
    • If suspicious lesion is identified from initial cystoscopy > rigid cystoscopy - under general anaesthetic for more definitive assessment
    • Tumours identified will require biopsy and potential resection via transurethral resection of bladder tumour (TURBT), either on initial assessment (if appears superficial) or following biopsy results
  • Imaging:  CT staging
  • Urine cytology


How are bladder cancers managed? 

MDT discussion

  • Carcinoma in-situ or T1 tumours: resected via TURBT: Transurethral Resection of Bladder Tumour  - resection of bladder tissue by diathermy during rigid cystoscopy.
  • High risk disease: adjuvant intravesical therapy, such as Bacille Calmette-Guerin (BCG) or Mitomycin C. 
    • Or Radical cystectomy: high-risk disease or limited response to initial treatments.
  • Superficial bladder tumours: high rate of recurrence, with around 70% recurring within 3 years, and these recurrences are more likely to be more invasive. Patients require routine follow-up with regular surveillance via cytology and cystoscopy.
  • Muscle-invasive bladder cancer: radical cystectomy +/- neoadjuvant chemotherapy, typically with a cisplatin combination regimen.
    • Urinary diversion:
      • Ileal conduit formation with urine draining via a urostomy
      • Bladder reconstruction, from a segment of small bowel* (often termed a neobladder) and urine draining urethrally or via catheter


What are the most common types of prostate cancer? 

How is prostate cancer investigated? 

What scoring system is used? 

  • Adenocarcinomas (>95%) - >75% of prostate adenocarcinomas arise from the peripheral zone
    • Acinar adenocarcinoma (most common)– originates in the glandular cells that line the prostate gland
    • Ductal adenocarcinoma – originates in the cells that line the ducts of the prostate gland

Scoring system: Gleason Scoring SYstem (lowest 3+3)


  • Bloods: PSA (can become artificially raised with several other conditions, including BPH, prostatitis, vigorous exercise, ejaculation, and recent DRE, reducing its specificity)
    • Can also use free:total PSA ratio, PSA density 
  • Biopsies of prostatic tissue
    • Transperineal (Template) biopsy: sampling prostatic tissue transperineally in a systematic manner, done as a day case under general anaesthetic. good for anterior
    • TransRectal UltraSound-guided (TRUS) biopsy: sampling the prostate transrectally, usually under local anaesthetic
    • Repeat prostate biopsy: after previous negative biopsy is recommended for men with rising or persistently elevated PSA and/or suspicious DRE
