Atraumatic partial nephrectomy. Experience with 112 consecutive patients.
The aim of the described method of partial nephrectomy is to minimize injury to the kidney, if possible without causing unnecessary loss of blood, and without interrupting the arterial or venous blood flow during surgery. Use of a pedicle clamp, compressing forceps for the renal parenchyma or hypothermia is superfluous. Following pre- and intraoperative estimation of the dimensions of the area of the renal parenchyma to be removed, virtual hemostasis is achieved by applying a continuous U-shaped suture distal to the portion of the kidney to be resected, using an atraumatic chromic catgut suture. Total hemostasis in the area to be excised is attained with the aid of a second U-shaped suture, running parallel to the first but entering on the opposite renal margin. Following excision, the raw surfaces are then reapproximated by means of a continuous suture and thus sealed. To conclude the operation a temporary nephrostomy is inserted. The immediate and later follow-up results and the advantages and potential complications of the new technique are described in 112 consecutive patients presenting for treatment during a period of 12 years.
