Renal tumours — quick overview
- Renal tumours include malignant (RCC subtypes, collecting-duct, medullary) and benign (oncocytoma, angiomyolipoma) lesions.
- Investigation of choice for solid renal masses: Contrast-enhanced CT (CECT).
Renal cell carcinoma (RCC)
Key clinical features
- Classic triad: hematuria (≈50%), flank pain, palpable mass (triad present in ~15%).
- Other signs: weight loss, fever, paraneoplastic syndromes (↑ESR common, hypercalcemia, hypertension, polycythemia, Cushing's, Stauffer syndrome — reversible hepatic dysfunction).
- Metastasis: lungs most common.
Subtypes & important associations
- Clear cell RCC — most common; arises from proximal tubules; associated with VHL syndrome.
- Papillary RCC — often shows psammoma bodies; associated with long-term dialysis.
- Chromophobe RCC — best prognosis; histology shows pale cells.
- Collecting-duct / Medullary RCC — worst prognosis; medullary RCC associated with sickle cell trait/disease.
Imaging and pathology
- CECT: mass often arises from upper or lower pole and may extend into renal vein/IVC.
- Histology clues: "clear cells" for clear-cell, papillary architecture for papillary, eosinophilic oncocytes for oncocytoma (benign).
Alt: Page of notes on RCC staging and features
Staging (tumour extent — TNM T categories summarized)
- T0: No evidence of primary tumor.
- T1: Tumor ≤ 7 cm, confined to kidney.
- T2: Tumor > 7 cm, confined to kidney.
- T3: Tumor extends into major veins or perinephric tissues but not beyond Gerota's fascia.
- T3a: Into renal vein or its segmental branches.
- T3b: Into IVC below diaphragm (subdiaphragmatic).
- T3c: Into IVC above diaphragm (supradiaphragmatic) or invades vena cava wall.
- T4: Invades beyond Gerota's fascia and/or involves ipsilateral adrenal gland.
Management principles
- Partial nephrectomy (nephron-sparing): indicated for T1 (≤7 cm), especially polar/small tumours.
- Radical nephrectomy: remove kidney with Gerota's fascia, ipsilateral adrenal when involved, regional nodes (e.g., para‑aortic), and ureter to the pelvic brim when indicated.
- Ablative therapies (cryoablation/RFA): option for small tumours (<4 cm) in solitary kidney, bilateral disease, or unfit patients.
- Systemic therapy (targeted/immunotherapy) for advanced/metastatic disease; RCC historically less chemo/radio-sensitive.
Benign renal tumours
Oncocytoma
- Most common benign renal tumour; originates from oncocytes (many mitochondria).
- CT clue: central stellate scar; gross: tan/mahogany colour.
- Associated with Birt–Hogg–Dubé syndrome (multiple oncocytomas).
- Management: often partial nephrectomy if imaging/indication uncertain (Bosniak 3/indeterminate).
Alt: Notes page on oncocytoma and RCC
Angiomyolipoma (AML)
- Benign tumour of perivascular epithelioid cells containing fat, muscle, and vessels.
- Often sporadic; bilateral/multiple AMLs suggest tuberous sclerosis.
- Presentation: usually asymptomatic; can present with spontaneous retroperitoneal hemorrhage (Wunderlich syndrome) when large.
- Treatment: observe small asymptomatic lesions; intervene when >4 cm or symptomatic — options include selective angioembolisation or partial nephrectomy.
Wilms tumour (nephroblastoma)
- Most common pediatric renal malignancy; peak age 2–5 years.
- Presents as abdominal mass; usually does not cross midline (helps differentiate from neuroblastoma).
- Associated syndromes: WAGR, Beckwith–Wiedemann, Denys–Drash.
- Investigations: CECT for staging.
- Management: chemo + surgery ± radiotherapy — Wilms is chemo- and radio-sensitive (different from RCC which is resistant).
Renal tuberculosis — key complications & management
- Early lesion: papillary ulceration; progression can produce pseudo‑calculi, damaged (ghost) calyx, perinephric abscess, and putty/calcified kidney (nonfunctional).
- Ureteric sequelae: strictures, shortening, kinking, and the golf‑hole ureteric orifice.
- Bladder sequela: thimble bladder (fibrotic small-capacity bladder) — may need augmentation.
- Diagnosis: three early-morning urine AFBs / mycobacterial culture and CT urography.
- Medical: standard anti-tubercular therapy (ATT). Surgical options based on complications: drainage of abscess, ureteric re-implantation, Boari flap for lower ureter shortening, augmentation cystoplasty for small bladder.
Alt: Page with pyelonephritis and benign renal tumour notes
Pyelonephritis — specific forms
- Emphysematous pyelonephritis: gas-forming infection (commonly E. coli), seen in diabetics/immunocompromised; treat with antibiotics and percutaneous drainage, nephrectomy if refractory.
- Xanthogranulomatous pyelonephritis: chronic destructive infection (often Proteus), associated with staghorn calculi and non-functioning kidney; treatment often subcapsular nephrectomy.
Bosniak classification (renal cysts — imaging‑based management)
- I: Simple cyst — benign; no follow-up needed.
- II / IIF: Minimally complex; IIF requires imaging follow-up.
- III: Indeterminate cystic lesion — consider partial nephrectomy (surgical exploration).
- IV: Clearly malignant features (enhancing soft‑tissue components) — treat as renal cancer (partial/total nephrectomy).
Stones — ESWL (brief)
- ESWL principle: focused shock waves fragment stones noninvasively.
- Common complications: pain, hematuria, urinary tract infection, and "stone‑street" (ureter clogged with fragments).
- Contraindications include pregnancy and uncontrolled bleeding diatheses.
High-yield facts (for exams/recall)
- RCC classic triad: hematuria, flank pain, mass (triad uncommon).
- CECT is investigation of choice for renal masses.
- Partial nephrectomy is preferred for tumours ≤ 7 cm (T1) when feasible.
- Wilms tumour: common in children 2–5 years, usually chemo-sensitive and does not cross midline.
- Angiomyolipoma >4 cm or symptomatic → treat (embolisation or surgery).
- Emphysematous pyelonephritis occurs in diabetics and may require nephrectomy if drainage/antibiotics fail.
