Percutaneous drainage and sclerotherapy as definitive treatment of renal lymphangiomatosis.

We report the technique and outcome of percutaneous drainage and sclerotherapy as primary treatment of renal lymphangiomatosis. Between January and May 2009, two patients presenting with symptomatic renal lymphangiomatosis were treated in our department by a minimally invasive modality combining percutaneous drainage with repeated sclerotherapy. We retrospectively analysed recurrence, complications and patient satisfaction. In this limited case series, percutaneous drainage and repeated sclerotherapy proved to be safe and effective for treating renal lymphangiomatosis. This procedure provides a minimally invasive option for selected patients, potentially avoiding a surgical procedure and any risk of complications.
