What Causes Frequent Urination After Taking Cephalexin?

Need to rule out Enlarged Prostate .
Detailed Answer:
Hello
Thanks for query .Based on the facts that you have narrated your husband has undergone Knee replacement surgery very recently He was catheterized during surgery and for few days after surgery and has developed UTI .
The UTI that he has is mostly secondary to Catheterization. However looking at his age of 74 years the cause of UTI and frequency for urination could be due to Enlarged prostate which is common at this age .
Consult qualified Urologist for clinical and digital rectal examination and get following basic tests done to help in making diagnosis .
1) Urine culture (I think this is being done and report is awaited .)
2) Ultrasound scanning of abdomen
In he mean while continue taking antibiotics as per culture report along with Tomsulosin once daily .
Further treatment will be decided by him based on results of these tests and final diagnosis .
Hope I have answered your query ,Please feel free to ask if you have more questions .I shall be happy to help you .
Thanks and Regards.

Tomsulosin is alpha blocker that helps to improve urine flow .
Detailed Answer:
Hello
Thanks for follow up .
Tomsulosin is a smooth muscle relaxant which relaxes smooth muscles in prostate and bladder neck and there by helps to improve urine flow .
It is routine protocol to rule out Enlarged prostate particularly in old age patients before they are subjected to undergo any major surgery in lower limbs or spine .
(You have not stated whether these investigations were carried out before going for knee surgery).
It is common for elderly patients to trigger and precipitate the problem of existing enlarged prostate who do develop obstructive voiding symptoms or develop retention of urine after surgery.
His urinary problem is not due to any drug interaction .
Thanks and Regards.
