Cancer related pelvic pain can be debilitating and difficult to treat. Superior hypogastric plexus neurolysis (SHPN) is considered to be an option for adequately relieving pain, with fewer side effects and improving the quality of life
The superior hypogastric plexus (SHP) is one of the paravertebral sympathetic ganglia, located in the lower border of the L5 vertebra and upper part of the sacrum in the retroperitoneal space. It is considered as a continuity of the celiac plexus and the lumbar sympathetic ganglia. It is related to the bifurcation of the aorta and the ureters. The SHP has a sympathetic connection (both efferent and afferent fibers) with splanchnic nerves and aortic plexus. It innervates the viscera of the pelvis, including the urinary bladder, ureters, sigmoid colon down to the anal canal, and upper vagina SHP blockade can be performed either by ultrasound (US), fluoroscopic, computed tomography (CT) and Magnetic resonance imaging (MRI) techniques and it is conducted through anterior (transabdominal) or posterior (lateral, paramedian, oblique, transdiscal, or transvaginal) approaches These different imaging modalities and approaches have been described for SHPN to make it easier, safer and more accurate and satisfied to the patients

| Group US-guided | Other | An ultrasound system with a 5-2 MHz curved transducer will be used. The division of the abdominal aorta into the common iliac arteries was located using oblique sonography. Then, the transducer will image the body of the fifth lumbar vertebra, at which level bilateral common iliac vessels will be seen leaving a space in the midline. a 20 cm long, 22 gauge Chiba needle will be introduced into the hypogastrium, with out-of-plane technique to access the fifth lumbar vertebral body at its anterior-most point, so that injected drug spreads equally bilaterally along the anterior curvature of the fifth lumbar vertebral body.Suction was applied to the needle to confirm that it was not within a vessel and 10 ml of 50% ethanol will be injected for neurolysis. |

| Group fluoroscopy-guided | Other | The patient will be placed in the supine position. The L5-S1 inter-discal space was identified under fluoroscopy.After providing local cutaneous and subcutaneous anesthesia with 2% Lignocaine solution nearly 3-4 cm below the umbilicus, a 20 cm long, 22 gauges Chiba needle is advanced to the anterior portion of the 5th vertebral body under ongoing fluoroscopic guidance. Once bony resistance is reached, gently inject 2-5 ml contrast which typical reveals a characteristic triangular blob of contrast with no vascular opacification.Before injection the needle is aspirated to confirm there is no blood. A preliminary test dose of about 3 cc of 0.5% bupivacaine is then injected. If there is no change in heart rate or neurological status, rest of the 20 cc phenol 10% is injected slowly with intermittent aspiration. |
