[Parapelvic cyst of kidney].
OBJECTIVE
To study the clinical features, treatment and diagnosis of parapelvic cyst.


METHODS
Twenty-three patients of parapelvic cyst of the kidney were reviewed retrospectively. Fourteen cases (61%) complained of lumbar pain or discomfort, and 4 patients (17%) accompany hematuria and hypertension.


RESULTS
In 15 patients receiving surgery, 2 were treated by nephrectomy, one by radical nephrectomy for misdiagnosis. Postoperative diagnosis confirmed a cyst. Eight patients were treated conservatively for cyst being small and without clinical symptoms. Nineteen cases were followed up for 0.5 - 12.0 years.


CONCLUSIONS
Ultrasonography and CT scan are the main diagnostic methods. Enhanced CT is extremely helpful in differential diagnosis of hydronephrosis. Surgical management is suitable for big cysts, lumbar pain, hematuria, hypertension and other complications.
