Will Delaying Ureteral Stone Surgery Cause Permanent Kidney Damage? - Urology

More Info

Delaying ureteral stone surgery can indeed raise concerns about potential kidney damage, particularly if there is significant hydronephrosis (swelling of the kidney due to urine buildup). When a ureteral stone obstructs the flow of urine, it can lead to increased pressure within the kidney, which may cause renal parenchymal damage over time. However, the extent of this damage largely depends on several factors, including the duration of the obstruction, the degree of hydronephrosis, and the overall health of the kidney prior to the obstruction.

In your case, if the obstruction has been present for a short period (a few days), the risk of irreversible damage is relatively low, especially if the kidney function is still within acceptable limits. The kidneys are quite resilient and can often recover from temporary obstructions if they are relieved promptly. However, if the obstruction persists for an extended period, particularly beyond a week or two, there is a greater risk of permanent damage, including loss of kidney function.

During the waiting period before surgery, it is generally advisable to stay well-hydrated. Drinking plenty of fluids can help to potentially flush out smaller stones, especially if they are less than 0.5 cm in size. Increased hydration can also help reduce the concentration of minerals in the urine, which may contribute to stone formation. However, if the stone is larger or if the obstruction is significant, hydration alone may not be sufficient to resolve the issue.

In terms of monitoring your kidney function, it is essential to keep in touch with your healthcare provider. They may recommend periodic imaging studies, such as ultrasound or CT scans, to assess the degree of hydronephrosis and kidney function during the waiting period. If there are signs of worsening kidney function or if symptoms such as severe pain, fever, or urinary changes develop, it may necessitate earlier intervention.

In summary, while there is a risk of kidney damage associated with delayed ureteral stone surgery, the actual risk depends on various factors. Staying hydrated is beneficial, and it is crucial to maintain open communication with your healthcare provider to monitor your condition closely. If you experience any concerning symptoms or if your condition worsens, do not hesitate to seek immediate medical attention.
