Advanced Urologic Care

Laparoscopic surgery involves insuflating the abdominal cavity with gas in order to open up a space where one is able to operate on relatively large structures through small incisions. Laparoscopic surgery has now become the standard of care for removing most kidney tumors. There are numerous laparoscopic approaches and techniques for renal surgery. Dr. Maislos has been trained in the latest laparoscopic techniques.

The advantages of laparoscopic surgery include :


  • Less Pain
  • Much smaller incisions
  • No Need to Remove a Rib
  • Less Bleeding
  • Usually As Fast or Faster than Open Surgery
  • Cut Hospital Stay in Half
  • Dramatic Reduction in Recovery Time at Home

Dr. Maislos is able to remove the whole kidney or part of the kidney as needed using a pure laparoscopic approach. Other options include laparoscopic cryoablation where he exposes the lesion laparoscopically and then freezes it using ultrasound guidance. In addition, he also offers radiofrequency ablation of renal lesions to select patients.

Dr. Maislos has been trained to perform pure laparoscopic surgery as opposed to other techniques which involve making a sizeable incision to place a hand in the patient called hand assisted laparoscopic surgery. Pure laparoscopic surgery offers the benefits of not having to make this large incision, namely- less post operative pain and much less post operative scarring.

Renal Laparoscopic Options Include:


  • Total Laparoscopic Nephrectomy
  • Partial Laparoscopic Nephrectomy
  • Laparoscopic Cryoablation of a Renal Mass
  • Laparoscopic Nephroureterectomy
  • Radiofrequency Ablation of a Renal Mass
