NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE) [1st line] Adult Carcinoma in situ of the urinary bladder is a high-grade, flat urothelial malignancy that frequently presents with persistent irritative voiding symptoms such as dysuria, urgency, or hematuria without infection. Primary care physicians should urgently refer any patient with unexplained, sterile irritative voiding symptoms or hematuria to urology for cystoscopy and urinary cytology. No pharmacological treatment is initiated in primary care; intravesical BCG immunotherapy or surgical management is directed by urology. - Refer, with advice Peds Children follow the same pathway: recognise and refer. No primary-care medicine is implied. Source No dose - referral pathway, no medicine given in primary care Why Carcinoma in situ of the urinary bladder is a high-grade, flat urothelial malignancy that frequently presents with persistent irritative voiding symptoms such as dysuria, urgency, or hematuria without infection.

Caution Any suspicious urinary tract lesion needs prompt specialist evaluation given its malignant potential. No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
