[Management of idiopathic renal subcapsuler fluid collection: 10 cases report].
OBJECTIVE
To discuss the clinical characteristics of idiopathic renal subcapsuler fluid collection and its treatment.


METHODS
From 2009 to 2012, 10  patients with idiopathic renal subcapsuler fluid collection were treated at Urology Department of Peking University First Hospital and retrospective analysis  was performed.


RESULTS
These patients' ages were 19-73 years, with an average age of 39.9 years. All the patients were female. Their tumors were  excluded by image studies before any treatment. Eight cases were treated by percutaneous drainage, 1 by surgery, and 1 under active surveillance. The  patients were followed up for 3-15 months, with a median follow-up of 7 months. Recurrence occurred in 1 patient who took percutaneous drainage, and  later she took capsulectomy. All the other patients had satisfied results.


CONCLUSIONS
Idiopathic renal subcapsular fluid collection is a rare condition,  whose cause is still unknown. The aim of therapy is to relieve symptoms and release the compression to the kidney. Percutaneous drainage or  capsulectomy are both therapy options with satisfied results.
