Early specialist evaluation leads to better treatment results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can visit my official homepage <a href=\"https:\/\/drsoaraweeurology.com\/\">here<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions About Radiation Cystitis<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is radiation cystitis and who gets it?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Radiation cystitis is chronic inflammation of the urinary bladder caused by pelvic radiotherapy \u2014 most commonly following treatment for prostate cancer, cervical cancer, or colorectal cancer. It affects approximately 5% of patients who undergo pelvic radiation. The bladder is susceptible because it sits within the radiation field targeting adjacent organs. Symptoms, particularly bloody urination, may appear within 3\u20136 months or as late as 10 years after completing radiotherapy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the most effective treatment for radiation cystitis?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hyperbaric oxygen therapy is the most effective treatment for stable-phase radiation cystitis, achieving up to 96% success rate at 6-month follow-up. It works by increasing bladder tissue oxygenation to reverse the hypoxic injury caused by radiation. Other options include oral Pentosan polysulphate (onset 1\u20138 weeks), intravesical Hyaluronic acid instillation (up to 92% response rate), and intravesical Formalin (60\u201390% response but higher risk). Urinary diversion is reserved for refractory cases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What should I do if I develop bloody urine after pelvic radiation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Any episode of bloody urination (hematuria) following pelvic radiotherapy should be evaluated by a urologist promptly. The initial management focuses on ruling out other causes (such as urinary tract infection), controlling active bleeding through bladder irrigation or endoscopic hemostasis if needed, and stabilizing the patient. Once the active bleeding is controlled, a tailored long-term treatment plan is formulated based on severity and response to therapy. Do not ignore hematuria after pelvic radiation \u2014 early evaluation leads to better outcomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have developed bloody urination after pelvic radiation therapy, Dr. Soarawee Weerasopone offers specialist consultations at Bangkok Hospital Headquarters. <a href=\"https:\/\/www.bangkokhospital.com\/en\/bangkok\/doctor\/dr-soarawee-weerasopone-2\">Book a Consultation<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Disclaimer:<\/strong> This content is written and reviewed by Dr. Soarawee Weerasopone, a board-certified urologist at Bangkok Hospital Headquarters.
