Areas of special interest

Kidney transplant surgery

Dr Mukherjee has performed 312 kidney transplants till date. He is an pioneer in the laparoscopic kidney donor harvest for kidney transplantation. This allows the kidney donor to recover safely and rapidly from the surgery.

Dr  Avishek Mukherjee is also highly skilled in the vascular surgery needed to join the graft kidney vein and artery to the iliac artery and vein of the recipient.

With Kidney transplant we can provide dialysis free life to 19 out of 20 patients who have undergone kidney transplantation.


Urethra is often neglected but is an essential organ for the patient for the rest of his life. The urethra can stricture due to various diseases. These strictures are best managed by urethroplasty.

Dr avishek mukherjee is one of the pioneers in the field of urethroplasty. This can be performed by harvesting a part of the buccal mucosa, the red wet skin inside our cheeks,  and then using this mucosal graft to recreate the urethra.

However, in many cases he also performs urethral augmentation by attaching the splayed urethra to the corpora cavernosa. This procedure has excellent recovery and long-term function.

Uro- oncosurgery

Dr Avishek Mukherjee has been one of the pioneering surgeons in the field of uro- cancer surgery. He was one of the earliest surgeons to adopt minimall access surgery techniques, to successfully treat cancers of kidney, ureter, bladder and prostate.
Kidney cancer surgery
Kidney cancers are one of the most common cancers. They were classicallybtreated by open radical surgery. But Dr Mukherjee is a expert in laparoscopic kidney cancer sugery. When the cancers are smaller than 4cm, then nephron sparing approach can be performed.
This means removing the cancer, while sparing the rest of the unaffected kidney. Dr Avishek Mukherjee is one of the pioneers who can perform this immensly complex procedure totally by laparoscopy.

Bladder cancer surgery

When the bladder cancers become invasive the entire bladdet and prostate have to be surgically removed. This requires a very major surgery. Dr Avishek Mukherjee has successfully treated many patients by minimall access radical cystoprostatectomy. With excellent recovery.

Prostate cancer surgery

Prostate cancer is a very common cancer affecting men. This cancer, when detected early by PSA blood testing can be cured by laparscopic radical prostate surgery. These patients generally have very good quality of life and long term survival. This surgery is performed very efficiently at NKPC by totally laparoscopic technique.

Our Doctors

Laparoscopic Kidney Donor Harvest

Once the patient has been selected for the donor. The patient is prepared for surgery. The best approach to remove the donor kidney is by laparoscopy, since the kidney is least handled and trauma is less therefore the organ is delivered to the recipient team in the most pristine fashion.

Generally we use a five port approach to access the kidney and the organ is finally delivered by a small incision

Once the renal vessels have been disconnected the kidney has to be rapidly delivered and then cooled so that there is no nephron damage.

Generally we have been able to maintain a warm ischemia time of less than 10mins

Recipient Surgery
  • While the donor team is preparing the kidney for harvest. The transplant recipient team prepared the bed for the donor kidney.
  • The kidney is best placed in the right lower part of the abdomen, where the blood supply is attached to the vessels going towards the legs of the patient.
  • The ureter is then attached to the bladder over a stent and therefore the procedure is completed.

Process Of Kidney Transplantation

Which patient are qualified to renal transplantation?

Any patient with chronic renal disease wherein the nephrologist opines that the kidney function can never return to normal is qualified to transplant. Provided the basic reason for renal impairment is manageable and therefore the new kidney will not be damaged after transplantation. For example if diabetes is the reason for renal damage then the patient should be adequately controlled so that the new transplanted kidney is also not affected by the diabetes.

When is transplantation indicated?

Whenever the kidney impairment is deemed permanent and the patient has otherwise a very long expected survival, these patients should be screened for transplantation since these patients will benefit the maximum from transplantation.

Who can donate the kidney to these patients?

The best donor are those who are directly related to the patient and are therefore emotionally deeply attached to the patient. However sometimes such individual is unavailable then unrelated person can also donate provided there is on coercion or financial transaction involved.

What are the legal requirement for these cases?

All these patients are then screened by the transplant coordinator and then the file is submitted to the department of health. Once the clearance is reached from swasthya bhaban only then we can proceed to the transplantation.

What are the criteria to match for transplantation suitability?

Once a donor has been selected the suitability for the transplantation is assessed by blood group cross matching, and HLA matching. Also the potential donor should have normal renal function to begin with. The left kidney is preferred as the donor kidney in which case the blood supply of the kidney is also assessed since single renal artery and vein are preferred for the donor kidney so that it is technically easier to perform the transplantation.
