Key to Success: A Scientific Hydration Plan
For patients requiring intermittent catheterization, a scientifically planned and reasonable hydration schedule is a crucial factor to ensure treatment success and maintain bladder health. Many people may overlook the impact of fluid intake volume and timing on bladder function, but these factors directly affect catheterization effectiveness and the patient’s quality of life.
Why is Scientific Hydration So Important?
The bladder is an elastic organ that stores and empties urine. For patients undergoing intermittent catheterization, regular filling and emptying of the bladder help maintain its capacity and contraction function, preventing over-distension or functional decline.
Excessive fluid intake can cause frequent and excessive bladder expansion, increasing bladder pressure and potentially leading to urine reflux or bladder wall damage, thereby increasing the risk of infection. On the other hand, insufficient fluid intake may cause concentrated urine, raising the risk of urinary tract infections and possibly impairing smooth urine flow.
Generally, 1 to 2 days before starting catheterization, healthcare professionals will teach patients how to follow a hydration plan: distribute fluid intake evenly over 24 hours, with a total daily intake controlled between 1500-2000 ml; avoid drinking water from 8 p.m. to 6 a.m. the next morning.
At the same time, it is important to avoid beverages with diuretic effects such as strong tea, coffee, and alcoholic drinks, and to reduce consumption of spicy and irritating foods.

When the residual urine volume is less than 100 mL or below 20% of the bladder capacity, that is, once bladder function has reached a stable balance, intermittent catheterization may be discontinued.

Effect of Combining a Drinking Plan with Intermittent Catheterization
A well-designed drinking plan combined with intermittent catheterization can significantly reduce the incidence of urinary tract infections, promote recovery of bladder function, alleviate urinary incontinence symptoms, and improve patient comfort and quality of life. By regularly controlling urine production and bladder emptying, the bladder can be maintained in a healthy state, avoiding overdistension and related complications.
Conclusion
Successful intermittent catheterization does not rely solely on correct catheterization techniques; a scientific drinking plan is equally essential. Each patient should develop an individualized drinking plan under the guidance of healthcare professionals, appropriately manage daily fluid intake, protect bladder health, and achieve a better quality of life.
