The onset of cystitis during intravesical chemo-immunotherapy for the treatment of non-muscle invasive transitional cell bladder tumor, or after pelvic radiotherapy mainly for prostate cancer, is a frequent clinical situation, not easily manageable due to the lack of responsiveness to symptomatic drugs, often resulting in discontinuation of cancer treatment in many cases.?The similarity of symptoms with those of the painful bladder syndrome, otherwise called interstitial cystitis, has led us to use the same treatment with intravesical sodium hyaluronate in order to obtain an improvement of symptomatology. We therefore performed a prospective study on 55 consecutive male symptomatic patients, aged from 54 to 81 years: 11 after radiotherapy, 17 after BCG and 27 after Mitomicyn C bladder instillations ,12 of whom in combination with bladder hyperthermia.?All subjects underwent bladder instillations with sodium hyaluronate 40 mg in 50 mL weekly for 8 to 24 weeks depending on the time needed to the resolution of the symptoms.?During the first 4 weeks 32 mg of dexamethasone were also instilled intravesically, mixed with hyaluronate, in order to obtain a stronger anti-inflammatory activity due also to its higher capacity of penetration in the bladder mucosa. The symptoms intensity was evaluated through a Visual Analogue Score (VAS) of the discomfort and pain perceived from 0 to 10, and bladder capacity was recorded with micturition diary before and after the treatment.?After 16 weeks VAS improved in every case of chemical cystitis from an initial mean value of 8.6 to a final mean value of 1(with 3 as a maximum value recorded). The difference was highly significant (p <0.001). Bladder capacity increased in all cases of chemical cystitis from a mean value of 56 to 276 mL with a highly significant improvement (p <0.001) and in all cases of post-actinic cystitis from a mean bladder capacity of 89 to a final mean value of 239 mL, with a significant improvement (p= 0.05). We did not observe any side effect due to our treatment. Therefore, we can conclude that bladder instillation with sodium hyaluronate for at least 8 weeks and dexamethasone in the first 4 weeks can solve the symptoms of iatrogenic cystitis secondary to chemo-immunotherapy or pelvic radiotherapy, without incurring in side effects. To our knowledge this treatment has never been published before in scientific medical literature.
Many treatment options for stress urinary incontinence are difficult to apply to neurological patients. Urolastic is a new agent that is primarily indicated for women with mild stress urinary incontinence or men after prostate surgery. In this report, we present a series of 5 cases describing the first use of Urolastic to treat neurological patients. All patients were evaluated with a voiding diary and the use of auxiliary devices as the main indicators of continence. The median operative time was 30.8 minutes, and no complications were observed. Of the 5 patients, 4 reported improved incontinence: 2 switched from diapers to small pads, while the other 2 patients were able to discontinue urinary condom use. The only instance of treatment failure occurred in a patient with a low-compliance bladder. The advantages of this procedure appear to include a soft-cuff effect, reversibility, and minimal invasiveness. However, a future randomized study would be necessary to validate this treatment option.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
