[Middle-aged and elderly patients with hydronephrosis induced by ureteric obstruction: etiology and diagnosis].

OBJECTIVE

To improve the etiologic diagnosis of middle-aged and elderly patients with ureteric obstruction.

METHODS

The etiology and diagnosis were retrospectively studied in 141 middle-aged and elderly patients with hydronephrosis in recent 10 years.

RESULT: 59 patients had ureterolithiasis, 51 ureteric cancer, 11 ureteric tuberculosis, 9 UPJ stricture, 6 uretero-cyst and 5 ureteric polyp.

CONCLUSIONS

Ureterolithiasis and ureteric cancer contribute greatly to ureteric obstruction in middle-aged and elderly patients. Etiologically, B ultrasonography is suggested to be used as the first choice in diagnosis and follow-up of the middle-aged and elderly patients with hydronephrosis, especially those accompanied with hematuria.
