Background: Cancer-related bladder spasms may be a rare but severe symptom of
bladder or metastatic cancer or its related treatments. Various treatments described
in the literature include systemic medications, intravesical or epidural medications, or
even sacral neurolectomies.
Objective: We present 3 patients who have suffered from bladder spasm
either from invasion of the bladder wall by tumor (2 patients) or from intravesical
chemotherapeutic treatment.
Design: Case Report.
Setting: Cancer pain management hospital.
Methods: For each patient, we describe the use of lumbar sympathetic block to
successfully treat the bladder spasms. Sympathetic blockade was performed at the
left anterolateral border of lumbar vertebra L4. We used 10 mL of local anesthetic
(0.25% bupivacaine) delivered in 2 mL aliquots, each given after negative aspiration
for heme. Each procedure was performed with fluoroscopic guidance (both AP and
lateral views) with the use of iodine contrast (Omnipaque-180) to confirm the location
of the medication and its resulting spread.
Results: All 3 patients had a reduction in the frequency and intensity of spasms,
with 2 out of 3 patients not having a recurrence of the spasms for up to 2 months
post procedure and follow up.
Limitations: Case Report.
Conclusion: Lumbar sympathetic blockade could be a useful treatment for recurrent
bladder spasm in the oncologic population. Based on these findings, we feel that the
branches of the sympathetic nerve set at L4 may be a good target for neurolytic
procedures, such as radiofrequency ablation, for long term treatment of bladder
spasms. Further research is necessary to determine the efficacy of this technique for
the treatment of bladder spasms in the oncologic population.
