Introduction
Lymphyocele by definition is the collection of lymph that is contained by a pseudomembrane. Management of lymphocele varies from simple aspiration or aspiration with sclerothreapy to more invasive technique, such as internal/external drainage. We present the results of 36 patients who developed pelvic lymphocele after renal transplant.
Materials and methods
A total of 1720 patients underwent living related donor renal allograft transplant at our centre. Of the total 1720 transplants 36 patients developed symptomatic lymphocele and underwent definitive management. Retrospectively analysis of the clinical data of these 36 patients was done.
Results
Thrirt six patients (2.09%) had a clinically significant lymphocele, which needed definitive management. All these patients underwent ultrasound guided drain placement and sclerosant injection. Fifteen out of 36 patients (41.6%) had successful treament with percutaneous drain placement. Laparoscopic marsupialization of lymphocele was done in 21 patients who failed percutaneous drain insertion therapy after diagnostic aspiration. Laparoscopic Marsupilization was successful in 18 out of 21 patients (85.7%). The 3 patients with failed laparoscopic marsupialization were managed with open surgical marsupialization.
Conclusion
Significant number of lymphocele post renal transplant may be asymptomatic but still cause deterioration of renal function even without causing obstructive uropathy. Lymphoceles causing renal deterioration or symptoms should be managed in a step ladder fashion starting from percutaneous drainage to laparoscopic marsupilization to open surgical approach. Asymptomatic recurrences post marsupialization are common and should be only closely observed unless they become symptomatic or cause deterioration of renal function. A systematic protocol may help in treating these patients better.
