title: [Diagnosis and treatment of hydrocephalus-accompanied renal calculi complicated with renal tumor: 5 case reports].
abstract: OBJECTIVE
  To investigate the diagnosis and treatment of renal pelvic tumor combined with renal urinary calculi and hydronephrosis.
  
  
  METHODS
  Five patients with renal pelvic tumor who underwent relief of the upper urinary obstruction were reviewed.
  
  
  RESULTS
  One of the cases lost the opportunity of surgical therapy when pelvic tumor was detected at the advanced stage, and the other 4 cases had received surgery and were followed up.
  
  
  CONCLUSIONS
  As pelvic tumor progresses rapidly after the renal blood flow is improved, and renal urinary calculi with hydronephrosis relieved; the patients with renal pelvic tumor need early diagnosis, aggressive treatment and close follow-up.
