[Middle-aged and elderly patients with hydronephrosis induced by ureteric obstruction: etiology and diagnosis]
1Department of Urology, People's Hospital, Beijing Medical University, Beiging 100044, China.
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.
