Purpose: This study reports our experience with CT-guided block in the superior hypogastric plexus, using a single needle and anterior approach, in patients with pelvic cancer.
Method: Ten patients with pelvic malignancy underwent CT-guided hypogastric neurolytic block with alcohol via an anterior approach. A solution of 10, 15, or 20 ml of alcohol, 4 ml of bupivacaine HCl, and 2 ml of contrast medium was injected. The results were evaluated based on pain relief, using a four-grade analogue scale.
Results: CT images always showed spread of solution around the iliac vessels. Pain relief was complete in four cases, moderate in two, mild in three, and none in one. Best results were observed with the largest amounts of alcohol.
Conclusion: CT-guided percutaneous superior hypogastric block is a safe, relatively easy, and effective procedure in patients with severe pain from pelvic malignancies.

Background: Uterine fibroid embolization can be associated with significant pain due to fibroid ischemia and interventions of the procedure itself. Fentanyl and midazolam are commonly provided for sedation and pain relief, but are not tolerated by all patients. This report outlines a novel pain management strategy for uterine fibroid embolization in a patient who could not receive either opioids or benzodiazepines.

The superior hypogastric plexus (SHP) contains afferent nociceptive fibers from the pelvic structures, thus the SHP block is employed in the chronic pelvic pain (CPP) treatment in patients who do not respond to conservative treatments. A 60-year-old female patient, who did not respond to conservative treatment, underwent SHP neurolytic block after a successful diagnostic block. An excessive oblique angle approach was applied due to physical restrictions, the needle passed through the intervertebral disc resulting in the contralateral side SHP block, and the procedure was also repeated to the other side SHP.

Anorectal neuropathy causes anorectal dysfunction, yet it is poorly recognized. This stems from both a lack of understanding of the extrinsic and intrinsic innervation of the anorectum and tools for evaluation of neuronal function. Our objective was to provide an improved understanding of the neuronal networks of the anorectum and discuss its functional significance.

Oblique lumbar interbody fusion (OLIF) is a minimally invasive lateral lumbar fusion technique and patients are discharged 1-2 days after surgery. Because OLIF utilizes a retroperitoneal approach close to the superior hypogastric plexus, postoperative urinary retention (POUR) may not be an uncommon problem. The purpose of this study was to present the incidence and outcomes of POUR with a systematic care protocol.

Chronic abdominal visceral pain management often requires multidisciplinary collaboration. Image-guided visceral nerve interventions may be critical in the management of visceral pain refractory to medical treatments. Abdominal and pelvic pain is mediated by specific nerves involving specific ganglia.
