Mr. Grigorios Kyriazis is a Consultant Urological and Robotic Surgeon in Yorkshire, specializing in minimally invasive surgery for various urological conditions, particularly robotic kidney surgery. He performs robotic procedures for both cancerous and benign kidney conditions, including partial nephrectomy, radical nephrectomy, pyeloplasty, and ureteric reconstruction. Mr. Kyriazis has successfully completed over 300 robotic kidney operations, with a focus on precision, kidney preservation where appropriate, careful planning, and patient-centred care.
A partial nephrectomy involves removing a kidney tumour while preserving the healthy part of the kidney.
Where it is technically and oncologically appropriate, this approach may preserve more kidney function than removing the entire kidney. During surgery, the tumour is carefully separated from the surrounding kidney, removed and sent for laboratory analysis. The remaining kidney is then reconstructed.
Partial nephrectomy can be technically demanding, particularly when a tumour is large, deeply situated or close to important blood vessels or the kidney’s collecting system. Careful review of the scans is therefore essential before surgery.
Mr Kyriazis uses detailed preoperative imaging and, in selected complex cases, three-dimensional kidney reconstructions to help plan the operation.
Most kidney operations are performed through the abdominal cavity. However, selected kidney tumours can be approached directly from behind the abdominal cavity using a retroperitoneal approach.
Potential advantages in appropriately selected patients may include:
The retroperitoneal approach is not suitable for every tumour. The choice between retroperitoneal and transperitoneal surgery is based on the tumour’s location, size and complexity, as well as the patient’s anatomy and surgical history.
Mr Kyriazis has extensive experience in both approaches and was instrumental in establishing robotic retroperitoneal partial nephrectomy within his NHS Trust.
A radical nephrectomy involves removing the whole kidney and, when clinically necessary, some surrounding tissue.
This may be recommended when a kidney tumour is too large or complex for partial nephrectomy, when the affected kidney has limited function, or when complete removal provides the safest cancer treatment.
The decision between partial and radical nephrectomy is made carefully. Tumour control remains the priority, but kidney preservation is considered whenever it can be achieved safely.
Pyeloplasty is an operation used to treat pelvi-ureteric junction obstruction. This is a narrowing where the kidney joins the ureter—the tube carrying urine from the kidney to the bladder.
The narrowed segment is removed and the healthy ureter is reconnected to the kidney to allow urine to drain more freely. A temporary internal ureteric stent is usually inserted and removed after the operation.
Robotic surgery allows the reconstruction to be performed through small incisions with precise suturing.
Damage, scarring or narrowing of the ureter can obstruct urine drainage and potentially affect kidney function.
Depending on the location and length of the affected segment, robotic reconstruction may involve:
These operations require individual planning. Existing scans, kidney function and the length and location of the obstruction are assessed before recommending treatment.
A nephroureterectomy involves removing the kidney, the entire ureter and a small cuff of bladder around the ureteric opening.
It is most commonly performed for selected cancers arising from the lining of the kidney or ureter, known as upper urinary tract urothelial cancers.
The need for surgery depends on the tumour’s location, grade, stage and the function of both kidneys. Some lower-risk tumours may be suitable for kidney-preserving treatment instead.
