Studies on renal damage from percutaneous nephrolitholapaxy.

L Ekelund, E Lindstedt, S B Lundquist

    The Journal of Urology
    |April 1, 1986
    PubMed
    Summary

    Percutaneous nephrolitholapaxy (PNL) for kidney stones generally preserves renal function. Most patients recover normal kidney function within two weeks after the procedure.

    Area of Science:

    • Nephrology
    • Urology
    • Medical Imaging

    Background:

    • Kidney stones are a common ailment.
    • Percutaneous nephrolitholapaxy (PNL) is a minimally invasive surgical procedure for kidney stone removal.
    • Detailed assessment of PNL's impact on renal function is crucial.

    Purpose of the Study:

    • To comprehensively evaluate the effects of percutaneous nephrolitholapaxy on renal function.
    • To assess changes in kidney function before and after PNL.

    Main Methods:

    • Preoperative and postoperative investigations included excretory urography, gamma camera renography, and computerized tomography.
    • Postoperative assessments also involved antegrade nephrostography and renal angiography.
    • The procedure involved single-stage nephrostomy, tract dilation, and stone removal under epidural anesthesia.

    Main Results:

    • Temporary decrease in renal function was observed on postoperative day 1, with most cases returning to baseline levels by 2 weeks.
    • Computerized tomography revealed Gerota's fascia thickening and perirenal hematomas in several patients.
    • Renal angiography showed parenchymal scarring in some patients and one arteriovenous fistula.

    Conclusions:

    • Percutaneous nephrolitholapaxy is generally well-tolerated by the kidney.
    • While temporary functional changes occur, renal function typically recovers post-PNL.
    • The study highlights the safety and efficacy of PNL in managing kidney stones.
