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.


Areas of special interest

Kidney and ureter stone surgery

Kidney stone surgery has had major changes in the last few years. Today with the availability of holmium laser we can use finer instruments and also flexible instruments to deliver the laser energy and destroy the stone,  in situ. Dr Avishek Mukherjee has been treating stone diseases for the past 23 years. He provided complete end to end solution for the stones of the urinary tract.

Ureteroscopic stone surgery-treating larger ureteral stones with laser energy. Ureter is the tube which conveys the urine from the kidney to the urinary bladder.

PCNL surgery-for large kidney stones, larger than 20mm, we use percutaneous nephrolithotomy. Wherein even staghorn stones can be cleared in one or two sittings.

Mini Perc surgery-this Is a mini version of the PCNL, where in the scope used is just 12 french and therefore the trauma to the kidney is reduced and the patient can recover much faster.

RIRS surgery-for stones smaller than 10mm located within the kidney we can use the flexible uretero-renoscope. Which allows the surgeon to visualize each calyx clearly and destroy renal stones, with laser, via an instrument passed from the urine passage into the kidney.

Laser prostate surgery

Prostate is the gland which produces semen, and is therefore a reproductive organ. Prostate enlargement can cause obstruction to the urine passage, since it surrounds the urethra at the base of the bladder.

When prostate is enlarged it needs to be removed. Earlier we used to use TURP as the method to remove the prostate. But now the latest method is removal of the benign prostate by holmium laser. The Holmium laser surgery of the prostate is called HOLEP. It is better than the TURP since the bleeding is less and therefore the clearance of the prostate is better.

Laparoscopic surgery for cancer of the prostate

Prostate cancer is a common problem among men more than 60 years of age. Prostate cancer can be safely and effectively treated with laparoscopic surgery of the prostate cancer. This surgery means removal of the entire prostate with the seminal vesicles and the lymph nodes which drain the prostate, which can also harbor the cancer.

Laparoscopy allows the surgeon to operate with very high magnification camera, and therefore very fine dissection and removal of cancer is possible. Since the entire surgery is performed via small key hole incisions, therefore the patient has very less trauma and can return to work within one month of the surgery. Dr Avishek Mukherjee did the first totally laparoscopic radical prostate surgery in eastern India in the year 2005.

Laparoscopic surgery for kidney cancer

Kidney cancer is very common in men after the age of 50. Surgical removal of these cancers remains the mainstay of the treatment of these patients. Earlier we needed to place large incisions to remove the cancer. But nowadays we are

able to perform this surgery with very high precision using machine driven laparoscopic surgery.

This surgery reduces the bleed and the trauma to the patient and therefore we can give cancer freedom with less pain

Today for cancers smaller than 4cm, we can provide nephron sparing surgery. Which spares the functioning kidney while the cancer can be cured. This advanced surgery can also be performed by laparoscopy, and Dr Mukherjee is a pioneer in this surgery in easter India.

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.
