What is a pain in the stomach after urinating for a long time?

The symptoms of abdominal pain after holding urine for a long time may be caused by chronic cystitis or chronic prostatitis. Further examination is needed, including B-ultrasound examination of urinary system, routine examination of prostatic fluid and routine examination of urine. If chronic cystitis can continue to take some sensitive antibiotics orally, such as nitrofurantoin tablets, sulfadiazine tablets combined with some Chinese patent medicines for clearing heat and dampness, such as Sanjin tablets, Relinqing capsules, Bazheng capsules for at least 2-4 weeks, chronic cystitis can be effectively controlled. If it is clear that it is caused by chronic prostatitis after examination, tamsulosin capsules, doxazosin tablets, terazosin hydrochloride tablets and anti-inflammatory drugs for prostatitis can be selected, such as Qianlietong tablets and Longqing tablets, symptomatic treatment for at least 1-2 months, chronic prostatitis can be effectively controlled, and the symptoms will be completely cured.
