From the Research
The treatment for an ovoid calculus in the bladder urinary system typically involves surgical removal, with the primary approach being cystolitholapaxy, where a cystoscope is inserted through the urethra to fragment and remove the stone using laser or ultrasonic energy. This approach is supported by recent studies, such as 1, which highlights the effectiveness of minimally invasive techniques like transurethral cystolithotripsy with holmium-YAG laser in managing bladder stones. For larger stones, open cystolithotomy (surgical incision into the bladder) or percutaneous suprapubic cystolitholapaxy may be necessary, as seen in cases like the one reported in 2, where a huge bladder calculus caused acute renal failure and required open cystolithotomy.
Some key points to consider in the management of ovoid calculus in the bladder include:
- The size and location of the stone, which can influence the choice of treatment modality
- The presence of underlying conditions, such as urinary tract infections or bladder outlet obstruction, which need to be addressed to prevent recurrence
- The importance of increasing fluid intake to 2-3 liters daily after treatment to maintain dilute urine and prevent new stone formation
- The need for follow-up care to monitor for potential complications and prevent future stone formation, as emphasized in studies like 3, which highlights the importance of antibiotic prophylaxis and treatment in preventing complications after percutaneous nephrolithotomy.
Overall, the goal of treatment is to remove the stone, address any underlying causes, and prevent future stone formation, with the choice of treatment modality depending on the individual patient's needs and circumstances.
