Leakage of urine from bladder irrigation catheters may be related to bladder spasm, ureter blockage, and bladder hypercontractility. 1. Bladder spasm: when the bladder is stimulated, it causes the bladder to spasm and contract violently, which leads to urine leakage from around the catheter. 2. Urinary catheter blockage: as in the case of urinary tract infection disease, there may be some flocculent material in the urine, leading to blockage of the urinary catheter, thus causing leakage. At this time, the catheter should be replaced and bladder irrigation should be done regularly to keep the catheter open. 3. Hypercontractile bladder: If there is frequent leakage of urine, but the catheter is clear, it may be caused by more hypercontractile bladder. In this case, you can apply some drugs to relax the bladder (e.g. Solinacin), so as not to over-contract the bladder, thus reducing the occurrence of leakage. Other irritations, such as inflammation or catheter irritation, can cause urine to leak. If leakage is infrequent, there is usually no need for much intervention. If your condition permits, it is advisable to remove the catheter as soon as possible and resume voluntary urination to minimize the risk of urinary tract infection.
