From the Guidelines

After ureter surgery, it is crucial to prioritize preventing urinary tract infections to minimize the risk of severe complications, and thus, managing urine odor effectively requires adherence to prescribed antibiotic regimens and maintaining good hydration levels. To address the issue of urine odor after ureter surgery, several factors must be considered, including the potential for bacterial growth and the body's healing process. The surgery itself can lead to temporary changes in urine odor due to the presence of blood or the use of catheters, which can introduce bacteria into the urinary system [ 1 ].

Key Considerations:

  • Drinking plenty of water (at least 2-3 liters daily, unless otherwise advised by a healthcare provider) to dilute urine and help flush out the system, reducing the concentration of potential odor-causing substances.
  • Following the prescribed antibiotic regimen completely to prevent infection, as guided by best practice policy statements on urologic surgery antimicrobial prophylaxis [ 1 ].
  • Monitoring for signs of infection or other complications, such as fever, severe pain, cloudy or very dark urine, and reporting these to a healthcare provider promptly if they occur.

Managing Urine Odor:

Given the potential for bacteriuria after ureteroscopy without prophylaxis, which could be in excess of 30%, with an expected rate of febrile urinary tract infection of 4% to 25% [ 1 ], it is essential to take preventive measures seriously.

  • Ensuring good personal hygiene and proper catheter care (if a catheter is in place) can help reduce the risk of bacterial infection.
  • Being aware of the importance of completing the full course of antibiotics as prescribed, even if symptoms seem to improve before finishing the medication, to fully clear any potential infection. By focusing on prevention, hydration, and monitoring for complications, individuals can effectively manage urine odor after ureter surgery and support their overall recovery and well-being.

From the Research

Urine Odor After Ureter Surgery

  • There are no direct research papers to assist in answering this question regarding urine odor after ureter surgery.
  • However, some studies discuss the prevention of urinary tract infections (UTIs) in patients undergoing urological procedures, which may be relevant to understanding post-surgery complications 2, 3, 4, 5.
  • For example, a study comparing ciprofloxacin with cefotaxime as prophylaxis for percutaneous nephrolithotomy found that ciprofloxacin was more effective in preventing postoperative fever 3.
  • Another study discussed the use of ciprofloxacin extended release for treating UTIs, highlighting its efficacy and safety profile 4.
  • A randomized trial found that single-dose antibiotic prophylaxis did not reduce the risk of UTI in surgical patients after urinary catheter removal 5.
  • Post-operative urinary retention is a common complication of surgery and can increase the risk of catheter-associated UTIs, but this does not directly address urine odor 6.
