General Surgery · Urology: bladder pain syndrome
Sample itemA 45-year-old woman has chronic suprapubic pain relieved by voiding, urgency and nocturia, with sterile urine cultures. Cystoscopy under hydrodistension shows petechial haemorrhages and a reddish mucosal patch. What is the most likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Interstitial cystitis
Interstitial cystitis presents with suprapubic pain that is relieved by voiding, frequency and sterile urine. Cystoscopy with hydrodistension shows glomerulations and, in some patients, Hunner lesions. Biopsy is used to exclude carcinoma in situ.
Option by option
A. Carcinoma in situ of the bladder
Carcinoma in situ usually causes irritative symptoms with positive cytology and needs exclusion by biopsy.
B. Interstitial cystitis (correct)
Correct. Pain relieved by voiding with sterile urine and glomerulations suggests interstitial cystitis.
C. Radiation cystitis
Radiation cystitis requires prior pelvic radiotherapy, which is absent.
D. Tuberculous cystitis
Tuberculous cystitis shows sterile pyuria and a contracted bladder with a history of renal tuberculosis.
