What To Do About Blood In Urine After Kidney Stone Surgery

After undergoing procedures such as ureteroscopy or percutaneous nephrolithotomy, it is common for patients to experience mild hematuria (blood in urine). These procedures can cause minor trauma to the mucous membranes of the urinary tract, including the kidneys and ureters. Additionally, the use of ballistic, laser, or ultrasonic energy during the operation can also lead to some degree of mucosal irritation.

Following surgery, a double-J (DJ) stent is often placed inside the ureter to prevent postoperative narrowing and ensure proper drainage. Because the DJ stent is a foreign body, it can cause irritation to the ureteral and bladder lining, especially during physical activity. This irritation may result in intermittent hematuria. In most cases, the blood in the urine is not bright red and is considered normal as long as it remains light and does not increase in volume.

Patients should stay well-hydrated and urinate regularly to help flush the urinary system and reduce irritation. It is also important to avoid strenuous exercise, heavy lifting, and holding urine for prolonged periods. Typically, the hematuria subsides within two to three weeks after the DJ stent is removed.

It is worth noting that hematuria is a common occurrence after stone removal procedures, whether through flexible or rigid ureteroscopy or percutaneous nephrolithotomy. The body's reaction to the stent can vary depending on the material and individual sensitivity, often resulting in symptoms like mild blood in the urine or flank discomfort. These symptoms are usually temporary and do not require additional treatment unless there is a sudden increase in bleeding or severe pain.

In summary, while seeing blood in the urine after kidney stone surgery can be concerning, it is typically a normal part of the recovery process. Following post-operative care instructions and attending scheduled follow-ups will help ensure a smooth recovery.
