Background: The incidence of lymphocele after kidney transplantation ranges
from 0.6% to 18%. This study examines the use of laparoscopic ultrasound f
or the location of lymphoceles during laparoscopic drainage.
Methods: Between July 1993 and October 1998, we per; formed 147 kidney tran
splants. A symptomatic lymphocele was observed in 19 patients (12.9%). All
of these patients underwent peritoneal laparoscopic fenestration of the lym
phocele. The graft, kidney hilum, ureter, iliac vessels, and lymphoceles we
re identified by laparoscopic ultrasound.
Results: All but one patient were discharged within 24 h. One recurrence (5
.2%), which was successfully treated by laparoscopy, was observed at a mean
follow-up of 15.5 months. We had one complication (5.2%)-a left hydrocele
that occurred 2 days after drainage of a lymphocele located in the left ili
ac fossa.
Conclusions: Laparoscopic peritoneal drainage of posttransplant lymphoceles
shares the well known advantages of laparoscopy. Furthermore, laparoscopic
ultrasound is a useful tool that allows the recognition of anatomical stru
ctures and decreases the risk of iatrogenic lesions.
