Nephrectomy Open
Open Nephrectomy is a urological surgical procedure that removes a kidney through a direct abdominal or flank incision — performed for kidney cancer, non-functioning kidney, or chronic infection — providing complete and definitive kidney removal with direct access for complex or large tumours.
Overview
Open Nephrectomy provides direct, tactile access to the kidney and its vascular pedicle through a flank, anterior subcostal, or midline incision, allowing safe removal of kidneys with large tumours, severe inflammatory adhesions, or complex vascular anatomy that make laparoscopic approaches technically demanding. For radical nephrectomy, the kidney is removed along with Gerota's fascia, the ipsilateral adrenal gland, and regional lymph nodes in a single anatomical specimen. For simple nephrectomy, only the non-functioning kidney is removed for symptom relief. Despite laparoscopy being standard for most nephrectomies, the open approach remains essential for complex oncological cases.
Types of Open Nephrectomy
Open nephrectomy encompasses several approaches and extents of resection based on the indication and the anatomical requirements of each case.
- Open Radical Nephrectomy (kidney, Gerota's fascia, adrenal, and regional nodes en-bloc)
- Open Simple Nephrectomy (kidney alone for benign non-functioning kidney)
- Open Nephroureterectomy (kidney and entire ureter for upper tract urothelial carcinoma)
- Cytoreductive Nephrectomy (for metastatic RCC before or after systemic therapy)
- Open Partial Nephrectomy (tumour excision with kidney preservation for smaller tumours)
Risk Factors for Kidney Cancer and Benign Disease Requiring Nephrectomy
These conditions and risk factors predispose patients to kidney disease requiring nephrectomy as treatment.
- Smoking — the most important modifiable risk factor for renal cell carcinoma
- Obesity and hypertension associated with increased renal cell carcinoma risk
- Chronic kidney infections or calculi causing irreversible non-functioning kidney
- Von Hippel-Lindau syndrome causing bilateral multifocal clear cell RCC
- Occupational exposure to trichloroethylene and other industrial solvents
- Family history of renal cell carcinoma particularly clear cell type
Kidney Disease Symptoms Requiring Nephrectomy
These symptoms indicate significant renal pathology requiring specialist urological assessment and consideration of nephrectomy.
- Haematuria — blood in urine, which may be painless and intermittent
- Flank pain from renal tumour, hydronephrosis, or chronic pyelonephritis
- Incidental renal mass discovered on CT or ultrasound performed for another reason
- Renal tumour thrombus extending into the renal vein or inferior vena cava
- Recurrent severe urinary tract infections from a non-functioning obstructed kidney
- Significant weight loss, fatigue, and anaemia from advanced renal malignancy
- Palpable flank mass in advanced renal cell carcinoma
- Hypertension refractory to medical therapy from a non-functioning ischaemic kidney

Clinical Features
The technology, techniques and clinical approach behind our nephrectomy open.
Early renal artery ligation before any tumour manipulation reduces bleeding and embolisation risk
Complete Gerota's fascia preservation maintains the oncological envelope around the tumour
Retroperitoneal approach avoids peritoneal entry reducing bowel handling complications
Complete lymph node dissection performed en-bloc with the specimen when indicated
Surgical drain placed alongside the renal bed to monitor for post-operative haematoma
Preparation Instructions
After Open Nephrectomy, protect the flank incision from lifting and straining for 6 to 8 weeks — the muscle layers of the flank incision take longer to heal than laparoscopic port sites. Attend the histopathological results consultation at 2 to 3 weeks to discuss the final pathology and any requirement for adjuvant systemic therapy. Ensure regular hydration and kidney function blood tests to monitor the function of the remaining kidney. Contact your urology team immediately for fever, wound dehiscence, or haematuria after discharge.
The Procedure
Step-by-step guide to what you can expect during your nephrectomy open procedure.
Pre-Operative CT Staging and Vascular Planning
Your urologist reviews the contrast CT with arterial phase imaging to confirm tumour size, staging, venous involvement, and the vascular anatomy — particularly the number of renal arteries and the relationship of the tumour to adjacent organs before finalising the open approach.
General Anaesthesia and Flank Positioning
General anaesthesia is administered and you are positioned in the full lateral flank position with the affected kidney uppermost. A kidney rest is elevated under the hip to open the space between the lower rib and iliac crest for optimal surgical access.
Flank Incision and Retroperitoneal Entry
A flank incision extending from the tip of the 12th rib to the lateral border of the rectus abdominis provides direct retroperitoneal access to the kidney without entering the peritoneal cavity — reducing bowel handling and post-operative ileus.
Early Renal Artery Ligation
The renal artery is identified and ligated first — before any manipulation of the tumour — reducing intraoperative blood loss and preventing potential tumour embolisation during subsequent dissection of the kidney from surrounding structures.
Complete Kidney Mobilisation and Removal
The kidney is completely mobilised within Gerota's fascia — preserving the intact fascial envelope around the tumour — and the renal vein, remaining vessels, and ureter are sequentially ligated and divided before the specimen is removed as a single intact unit.
Haemostasis, Drain, and Layered Closure
The renal fossa is inspected for haemostasis and a surgical drain is placed alongside the renal bed. The flank wound is closed in careful anatomical layers — fascial, muscular, subcutaneous, and skin — with strong interrupted sutures.
What to Expect
Open Nephrectomy is performed under general anaesthesia and takes 2 to 3 hours. The flank or abdominal approach provides direct access to the kidney, the renal artery and vein are individually ligated and divided, and the kidney is removed in its fascial envelope as a single intact specimen. The wound is closed in anatomical layers and a drain placed alongside the renal fossa. Most patients are comfortable mobilising from the day after surgery and are discharged within 5 to 7 days.
