Intravesical formalin for hemorrhagic cystitis following irradiation of cancer of the cervix.
OBJECTIVE
To determine the effectiveness of intravesical formalin instillation in hemorrhagic cystitis following irradiation of cancer of the cervix.


METHODS
Records were reviewed for 35 patients with hemorrhagic radiation cystitis who underwent treatment with 1% (n = 22), 2% (n = 10), and 4% formalin (n = 4), using Fair's technique.


RESULTS
Complete response was seen in 31 patients (89%) and partial response in 3 patients (8%) after a single instillation. Minor complications were seen in 19 patients (54%). Major complications occurred in 11 patients (31%), with 5 cases requiring subsequent urinary diversion. One patient died of persistent bleeding and probable formalin toxicity. Hematuria recurred in 7 patients achieving complete response at a mean period of 8 months after treatment. A 1% solution was as effective in controlling hematuria as higher concentrations and was associated with significantly less morbidity.


CONCLUSIONS
Intravesical instillation of 1% formalin is an effective treatment for intractable hematuria secondary to radiation cystitis.
