    Upper urinary tract obstruction compliance impacts renal function. Good compliance preserves kidney function, while poor compliance indicates impaired function, guiding clinical decisions.

    Area of Science:

    • Urology
    • Nephrology
    • Medical Imaging

    Background:

    • Upper urinary tract obstruction is a common clinical concern.
    • Assessing renal unit compliance is crucial for understanding obstruction severity.
    • Diuresis renography is a key tool for evaluating renal function in these cases.

    Purpose of the Study:

    • To measure upper tract compliance using pressure flow studies.
    • To evaluate the clinical implications of upper tract compliance.
    • To correlate obstruction degree, compliance, and renal function.

    Main Methods:

    • Review of 111 pressure flow studies.
    • Measurement of upper tract compliance.
    • Assessment of renal function using diuresis renography.

    Main Results:

    • Good compliance observed in 64 unobstructed and 16 obstructed renal units.
    • Obstructed systems with good compliance showed less significant obstruction.
    • Poor compliance in 31 obstructed systems was associated with impaired renal function.

    Conclusions:

    • Upper tract compliance is a significant factor in renal function preservation.
    • Good compliance in obstructed systems suggests less severe obstruction and better renal outcomes.
    • Correlation of obstruction, compliance, and function aids clinical management.
