Laparoscopic fenestration of lymphoceles after kidney transplantation with diaphanoscopic guidance.

In laparoscopic fenestration of lymphoceles after kidney transplantation, identification of the correct site of incision is sometimes difficult. We developed a new technique, using diaphanoscopy in 3 patients. After ultrasound-guided puncture and dilation, the correct incision site is identified by white light with a cystoscope inserted into the lymphocele cavity.
