Giant vesical calculas and anuria.

E Nygaard, T Terjesen

    Scandinavian Journal of Urology and Nephrology
    |January 1, 1976
    PubMed
    Summary

    A 50-year-old man developed severe kidney failure and stopped urinating due to a massive bladder stone. The stone weighed over 1.6 kilograms and was removed through surgery. This may be the largest bladder stone ever removed with the patient surviving. No other cases of such a large stone causing anuria have been reported. Four years later, the patient was diagnosed with bladder cancer. The delay in diagnosis was due to the patient’s lack of trust in doctors and hospitals. The case highlights the importance of early treatment for urological emergencies and the impact of patient behavior on health outcomes.

    Area of Science:

    • Urology
    • Nephrology
    • Clinical Case Studies

    Background:

    Ureteral and bladder stones are common causes of urinary obstruction. Most cases do not lead to complete anuria. Severe kidney failure often results from prolonged blockage. Prior research has shown that large bladder stones can cause significant symptoms. No prior work had resolved the risk of anuria from such stones. This gap motivated the documentation of a rare case. The patient’s lack of trust in medical care delayed diagnosis. This case highlights the importance of early intervention in urological emergencies.

    Purpose Of The Study:

    The aim was to report a rare case of anuria caused by a massive bladder stone. The patient presented with severe kidney failure. No prior reports of such a large stone causing anuria exist. The researchers wanted to emphasize the clinical significance of this condition. They also aimed to highlight the role of patient behavior in delayed diagnosis. The study sought to provide a detailed clinical description. It aimed to raise awareness among clinicians about similar cases. The documentation serves as a reference for future urological cases.

    Frequently Asked Questions

    A 1,640 g bladder stone was removed from a patient with anuria and uremia.

    Suprapubic lithotomy was performed to remove the stone due to its large size.

    Endoscopic techniques were not used because the stone was too large for such methods.

    The patient recovered from anuria and uremia after the stone was removed.

    Four years later, an inoperable bladder cancer was diagnosed in the patient.

    Main Methods:

    The patient was evaluated using clinical history and imaging. Suprapubic lithotomy was performed to remove the stone. The calculus was weighed and measured post-removal. No endoscopic techniques were used due to the stone’s size. The patient’s kidney function was monitored post-surgery. Follow-up occurred over four years after the initial treatment. A bladder cancer diagnosis was made during this period. The researchers analyzed the timeline of events and patient behavior.

    Main Results:

    A 1,640 g bladder stone was successfully removed. The patient recovered from acute kidney failure. No prior reports of such a large stone causing anuria exist. The stone was the largest ever removed with patient recovery. The patient remained anuric until the stone was extracted. Four years later, an inoperable bladder cancer was diagnosed. The delay in diagnosis was due to the patient’s distrust in medical care. The case highlights the consequences of delayed treatment.

    Conclusions:

    The authors suggest that large bladder stones can cause anuria. This case may be the largest documented with full recovery. The patient’s lack of trust in medical institutions delayed treatment. The researchers propose that early diagnosis is crucial in similar cases. No prior work had resolved the risk of anuria from such stones. The case underscores the importance of patient compliance. The authors suggest that clinicians should consider rare causes of anuria. This report serves as a reference for future urological emergencies.

    The authors suggest that patient distrust in medical care delayed both stone and cancer diagnosis.
