Objective: To investigate the epidemiology of
congenital obstructive nephropathy.
Methods: Forty-eight patients diagnosed as
congenital obstructive nephropathy were hospitalized in our hospital and
received operations. All the patients enrolled in this study had urine routine,
serum
creatinine and BUN analysis. They also received intravenous
pyelogram or retrograde pyelogram plus KUB and/or CT and B-ultrasonography.
Patients with other types of nephropathy were excluded.
Results: Among the 48 patients, 33(68.75%) of
them were diagnosed as congenital urethral obstruction and 11(22.91%) were
diagnosed as malformation of renal pevic and ureter. The onsets of the
diseases of 43 patients (87.50%) were before 20 years old. Both the
duration and type of the diseases have no relationship with the elevation
of serum creatinine,
haematuria and urinary tract infection (P>0.05).
Conclusions: Among the diseases the urethral
obstruction is the dominant one. Following it is the malformation of renal
pevic and ureter. Most of the patients are juvenile and adolescence. The duration
of the disease and type of the disease have no relationship with the
elevation of serum creatinine, haematuria and urinary tract infection.
