Brief Answer: Please, what are your symptoms? Detailed Answer: Hi and thank you so much for this query. I am so sorry to hear about this suspicion of a possible Urinary tract infection(UTI). Would you please report your symptoms so that I can look into and say whether they are suggestive of UTI or some other disease condition? With a negative urine culture, it would be very difficult to say you have a UTI. Symptoms of UTI can be related to other diseases like low hormones in the system, bladder irritation, etc. Let me hear from you to add more information to this. Nitrofurantoin after sex is used a preventive measure in clients who develop UTI after sex because this increases the risk of having a UTI. I hope this addresses your query fully. Thank you so much for using our services and do feel free to ask for more clarification or information if need be. I wish you well. Dr. Ditah, MD.

Brief Answer: Thank you!! Detailed Answer: Hi and thanks for following up with me. These symptoms especially of constant burning at the tip of the urethra may be suggestive of atrophic vaginitis secondary to menopause. This can be corrected by applying topical estrogens to relief the vaginal dryness and reduce irritation. The dryness is responsible for the hypersensitivity to urine and hours after urinating. The capital symptoms of UTI are frequent urination in small quantities. When these are absent, then UTI is very unlikely. And with a sterile urine examination, this is less likely. I will like you to read this page on atrophic vaginitis from a trusted site. Let me hear from you after reading to address any concerns and offer clarifications. Also, see whether it closely relates to your symptoms. Thanks and hope to hear from you. WWW.WWWW.WW Dr. Ditah, D.
