Background and Purpose: Bilateral nephrectomy is an infrequently performed procedure. The indications include bilateral masses too large for nephron-sparing surgery, recalcitrant hypertension in dialysis patients, pain, infection, reflux, or large symptomatic polycystic kidneys. Bilateral pretransplant purely laparoscopic nephrectomy for bilateral renal masses has not been reported previously. We present our experience with this procedure using five transabdominal trocars without having to reposition the patient.Methods: We employed a five-port technique in a middle-aged woman with end-stage renal disease who presented with an infected peritoneal dialysis catheter. On abdominal CT, she had bilateral enhancing renal masses. Six weeks after removal of the catheter, she underwent bilateral transperitoneal laparoscopic nephrectomy. The technique is described, and recommendations are made regarding potential obstacles.Results: The procedure was performed in 185 minutes, and the total hospital time was 41 hours. The estimated blood loss was 50 mL. Final pathology examination revealed a 5.5-cm right renal-cell carcinoma stage T1N0M0and left hydronephrosis, atrophy, nephrosclerosis, and thick-walled renal cysts without malignancy. On 3-month follow-up she is well, without complaints.Conclusion: Bilateral pretransplant purely laparoscopic nephrectomy can be performed without significant repositioning, redraping, and resterilization. In this case, operative time and cosmesis were acceptable, and surgical morbidity was low.
