Patient's question:
Okay, here is the translation following your instructions:A few days ago, the area outside and inside the urethral opening became very itchy. It's also very itchy every night even after washing. A small bump has grown. I've applied Dianping (Pityriasis Alba cream), but it's still very itchy.
Doctor's answer:
Analysis of the condition: This may be caused by a urinary tract infection. Urinary tract infections occur when bacterial colonies spread from the intestines and around the urethral opening to the urethra. Through urine reflux, bacteria reverse flow within the urinary tract and bind to corresponding receptors on the epithelial cells of the urinary tract, localizing and multiplying to produce inflammation.Recommendations: It is recommended to use quinolone drugs or broad-spectrum cephalosporin antibiotics intravenously for treatment. For patients resistant to β-lactam antibiotics and quinolone antibiotics, aztreonam can be selected.
