Lymph node dissection after cancer surgery can lead to swelling of an extremity due to the accumulation of fluid from obstruction of the lymph vessels. Sometimes, this problem cannot be treated medically, and can be very disabling. In penile cancer, nodes in the groin are dissected as part of the surgery. These investigators have assisted 4 patients who had serious leg swelling from lymphatic obstruction associated with lymph node surgery in penile cancer. The surgeons adapted a technique to use the testicular lymphatics or gonadal system to reduce the edema successfully. They have decreased patient discomfort and reduced leg circumference by more than 30% following their operation. They have concluded that this technique should be considered a surgical treatment option for this type of edema if it is unresponsive to treatment.
