GCC Context: High BPH prevalence in older male expat workforce. Many present late due to normalising LUTS. Screen proactively in men >50.
Transurethral resection of prostate — gold standard for moderate-severe BPH. A resectoscope is passed via the urethra and a diathermy loop shaves prostatic tissue under spinal or general anaesthesia.
Preferred — allows detection of early TURP syndrome signs (confusion, visual disturbance) while patient is awake.
Glycine 1.5% (monopolar TURP) — non-conducting, hypotonic. Risk of absorption → dilutional hyponatraemia.
TURP Syndrome: Caused by excessive absorption of hypotonic glycine irrigant into venous sinuses → dilutional hyponatraemia (Na <125 mmol/L), hypovolaemia, and glycine toxicity. A surgical emergency.
Note: Bipolar TURP and laser TURP (Holmium/GreenLight) use saline irrigant — TURP syndrome risk is eliminated. These are increasingly preferred in modern urology.
A 22–24Ch three-way Foley catheter is inserted post-TURP. The three channels are: irrigation inlet, drainage outlet, and balloon inflation. Balloon inflated to 30–50 mL to achieve haemostasis by pressure on the prostatic fossa.
Clot retention: Sudden stop in outflow + distended bladder + pain = blocked catheter. Perform gentle bladder washout with 50 mL sterile saline via Bladder syringe. Document and escalate if unsuccessful.
Expected post-TURP. Manage with CBI rate increase. Clot retention = blocked catheter; requires washout. Persistent bright red = surgical re-look may be needed.
Rare with bipolar/laser TURP. Dilutional hyponatraemia from glycine absorption. Treat as emergency — see TURP syndrome card above.
Ensure pre-operative MSU is clear. Give prophylactic antibiotics per local protocol. Post-TURP UTI rates are high in GCC due to indwelling catheters. Treat early with IV antibiotics if systemic signs.
Occurs in 65–90% of TURP patients. Semen passes into the bladder during orgasm rather than externally. Not harmful but causes infertility. Counsel pre-operatively.
Scarring from resectoscope trauma. Presents weeks–months post-op with poor stream. Diagnosed by flow rate/urethrogram. Managed by urethral dilation or urethroplasty.
Damage to external urethral sphincter. Usually transient. Manage with pelvic floor exercises. Persistent cases require urological review — consider artificial urinary sphincter.
CBI typically stopped at 24–48h when effluent is light pink/clear. Catheter balloon deflated to 10 mL (standard Foley) for 24h post-CBI. TWOC protocol:
GCC Context: The Gulf region has the highest global incidence of renal calculi. Chronic dehydration in desert climate, high ambient temperatures, high dietary protein, and low fluid intake all contribute. Stone recurrence rates exceed 50% at 5 years without preventive advice.
| Type | Frequency | Appearance on CT | Key Association |
|---|---|---|---|
| Calcium Oxalate | ~80% | Hyperdense | Hypercalciuria, dehydration |
| Struvite | ~10% | Staghorn pattern | Urease-producing organisms (Proteus) |
| Uric Acid | ~5–10% | Radiolucent on KUB X-ray | Gout, diabetes, acidic urine |
| Cystine | ~1% | Mildly opaque | Cystinuria — genetic disorder |
Uric acid stones are radiolucent — invisible on plain X-ray (KUB) but visible on CT. This is a classic high-yield exam distinction.
| Stone Size | Location | Expected Passage | Management |
|---|---|---|---|
| <4 mm | Any | ~95% pass spontaneously | Conservative — analgesia, hydration, strain urine, 4-week review |
| 4–10 mm | Distal ureter | ~50–80% with MET | Medical Expulsive Therapy (MET): Tamsulosin 400 mcg OD (alpha-blocker relaxes ureteral smooth muscle) |
| 4–10 mm | Proximal ureter / kidney | Less likely spontaneous | ESWL first-line; ureteroscopy (URS) if fails |
| >10 mm | Any ureteric | Unlikely to pass | URS + laser lithotripsy (ureteroscopy with holmium laser) |
| >20 mm | Kidney (staghorn) | Will not pass | PCNL (percutaneous nephrolithotomy) — first-line for large renal stones |
Do not delay analgesia pending investigations. Renal colic is one of the most severe pain experiences — treat immediately.
Non-invasive. Focused shock waves fragment stone externally. Best for renal stones <20 mm, good renal function. Not suitable in pregnancy, coagulopathy, or aortic aneurysm. Fragments passed in urine over weeks — may cause renal colic post-treatment.
Rigid/flexible ureteroscope passed up the ureter under GA. Holmium laser used for lithotripsy. Fragments retrieved with Dormia basket or left to pass. A JJ (double-J) ureteral stent is often left post-URS for 2–4 weeks to prevent ureteric oedema/colic.
Percutaneous track created into renal collecting system under X-ray/USS guidance. Nephroscope advanced for stone fragmentation. Best for large (>20 mm) or staghorn calculi. Nephrostomy tube left post-op. Complications: bleeding (10%), sepsis, pleural injury.
Painless frank haematuria = bladder cancer until proven otherwise. Requires urgent urology referral for flexible cystoscopy within 2 weeks regardless of age or absence of other features.
Do not treat UTI and discharge without investigating haematuria if UTI excluded on MSU. Treat infection and re-dipstick after course — persistent haematuria still requires urology referral.
Outpatient procedure under local anaesthetic gel (instillagel). Scope passed via urethra for direct bladder visualisation. Pre-procedure: consent, allergy check (latex, lidocaine), empty bladder. Post-procedure: encourage fluids, expect mild dysuria/haematuria for 24h, report fever or heavy bleeding.
Under GA/spinal. Resectoscope removes bladder tumour(s) for staging. Post-op: urethral catheter (24–48h), CBI if heavy haematuria, monitor outflow colour. TURBT provides tissue for histology — determines muscle invasion status (Ta/T1 vs T2+).
Used for high-risk non-muscle-invasive bladder cancer (NMIBC) — CIS, T1 high-grade, Ta high-grade. Instilled via urethral catheter and retained for 2 hours.
Used for low-to-intermediate risk NMIBC. Single early instillation within 24h of TURBT, or maintenance course. PPE required: gloves (double), apron, eye protection, mask. Cytotoxic waste disposal. Patient: retain 1–2h, void in toilet with lid, wash hands. Skin contact: wash immediately with soap and water.
For muscle-invasive bladder cancer (T2+) or recurrent high-risk NMIBC. Involves removal of bladder (+/- prostate in males, uterus/anterior wall in females). Urinary diversion required.
Segment of ileum used to channel urine from ureters to abdominal wall stoma. Urostomy — permanent. High output stoma; requires urostomy drainage bags (not standard stoma bags). Mucus in urine is normal (from ileum). Stoma nurse involvement essential.
Ileal reservoir fashioned and anastomosed to urethra. Patient voids by increasing abdominal pressure (Valsalva). Requires intact urethral sphincter. Risk of nocturnal enuresis — patient education essential. Self-catheterisation may be needed.
| Type | Channels | Use |
|---|---|---|
| Foley (2-way) | Drainage + balloon | Standard indwelling catheter |
| Foley (3-way) | Irrigation + drainage + balloon | Post-TURP, haematuria with CBI |
| Intermittent (Nelaton) | Drainage only (no balloon) | ISC, in-out catheterisation |
| Suprapubic | 2-way via abdominal wall | Urethral trauma, long-term retention |
| Coude tip (Tiemann) | 2-way, curved tip | BPH with difficult passage |
Common error: Advancing into vagina. If this occurs, leave that catheter in situ as a landmark, insert new catheter into meatus, then remove the first.
GCC Context: CAUTIs are a leading cause of hospital-acquired infection across GCC hospitals. DHA/HAAD/MOH quality indicators specifically track CAUTI rates. Bundle compliance is audited and reported to regulatory bodies.
Review catheter indication daily on ward rounds. Document indication clearly. Remove when no longer clinically indicated. Catheters for nursing convenience alone are not appropriate.
Full aseptic non-touch technique. Sterile gloves, sterile drape, sterile equipment. Use pre-packaged catheter packs. Avoid contamination of catheter tip or balloon port.
Never disconnect catheter from drainage bag without clinical reason. Maintain a closed, uninterrupted system. Sampling via needleless sample port with alcohol swab only.
Clean periurethral area with soap and water during daily hygiene. Avoid antiseptic wipes on meatus (disrupts protective flora). Maintain catheter drainage below bladder level.
Nurse-led catheter removal protocols reduce dwell time. Every additional day increases CAUTI risk by 3–7%. Use daily review checklists or automatic stop orders at 48–72h post-op.
Do NOT treat asymptomatic bacteriuria in catheterised patients — it is universal and treatment drives resistance. CAUTI requires: symptoms (fever, rigors, haematuria, new pain) PLUS positive urine culture (>10³ CFU/mL).
Urinary Retention Emergency: Painful, distended bladder + inability to void = acute urinary retention. Catheterise immediately. Do not delay. Drain up to 1,000 mL then clamp for 30 min — avoid rapid decompression haematuria (rare but reported).
GCC Cultural Context: Sexual health discussions require sensitivity to cultural and religious norms across Arab Gulf states. Patients may be reluctant to discuss ED openly. Same-gender consultation is often preferred. Use neutral, clinical language. Ensure strict privacy during assessment and document in a non-stigmatising manner.
ED prevalence in GCC is high — driven by cardiovascular risk factors (hypertension, diabetes, dyslipidaemia), sedentary lifestyle, obesity, and psychological factors. Type 2 diabetes is the single largest ED risk factor in the region.
Penile arteriosclerosis — marker of systemic CVD. CV risk factor modification is first-line treatment alongside PDE5i.
Diabetes (peripheral neuropathy), spinal cord injury, pelvic surgery, MS, Parkinson's. Post-prostatectomy neuropraxia.
Hypogonadism (low testosterone), hyperprolactinaemia, hypothyroidism. Check morning serum testosterone.
Beta-blockers, SSRIs, antihypertensives (thiazides, spironolactone), anti-androgens, opioids.
Anxiety, depression, relationship issues, performance anxiety. Clue: normal nocturnal erections. Refer for psychosexual counselling.
ABSOLUTE CONTRAINDICATION: Concurrent nitrates (GTN, isosorbide) — risk of fatal hypotension. Also contraindicated with alpha-blockers within 4h (risk of postural hypotension). Recent MI or stroke.
Radical prostatectomy (open or robotic) causes cavernous nerve neuropraxia — nerve recovery can take 12–24 months. Penile rehabilitation aims to maintain erectile tissue oxygenation during recovery.
Cylinder placed over penis; vacuum pump creates negative pressure to draw blood into corpora cavernosa. Constriction ring applied at base to maintain erection. Used daily as rehabilitation tool (without constriction ring) to maintain cavernosal oxygenation and prevent fibrosis.
Low-dose daily tadalafil (5 mg) started early post-operatively (nerve-sparing procedures) to promote smooth muscle preservation and cavernosal oxygenation. Continue for 12+ months as nerve recovery progresses.
Alprostadil (prostaglandin E1) injected into corpus cavernosum. Effective when oral PDE5i fails. Patient education on technique, dose titration, and priapism risk (>4h erection = emergency).
Ischaemic priapism >4 hours = urological emergency. Prolonged ischaemia leads to irreversible erectile dysfunction if not treated promptly.
GCC Exam Focus: This tab consolidates the highest-yield topics for DHA (Dubai Health Authority), DOH (Abu Dhabi), SCFHS (Saudi Commission), and QCHP (Qatar) urology nursing examinations. These topics appear repeatedly in past papers and clinical scenario questions.
Absorption of hypotonic glycine 1.5% irrigant through open venous sinuses during monopolar TURP. Volume overload + dilutional hyponatraemia + glycine toxicity.
| Size | Spontaneous Passage | First-Line Management | Drug Treatment |
|---|---|---|---|
| <4 mm | ~95% | Conservative (analgesia, hydration) | NSAIDs — diclofenac 75 mg IM/PR |
| 4–10 mm distal ureter | ~60–80% with MET | Medical expulsive therapy (tamsulosin) | Tamsulosin 400 mcg OD + diclofenac |
| 4–10 mm proximal/kidney | Less likely | ESWL (if eligible) | Analgesia while awaiting procedure |
| >10 mm ureter | Unlikely | URS + holmium laser | JJ stent post-procedure |
| >20 mm kidney | Will not pass | PCNL | IV antibiotics pre-op (struvite/staghorn) |
| Any + fever (infected) | N/A | URGENT DECOMPRESSION (nephrostomy or JJ stent) | IV antibiotics immediately (piperacillin-tazobactam) |
Exam tip: Asymptomatic bacteriuria in catheterised patients — do NOT treat. Treatment drives resistance. CAUTI requires symptoms + positive culture.
| Drug | Class | Urology Use | Key Nursing Points |
