INTRODUCTION AND AIM OF THE STUDY Spinal anesthesia for transurethral resection of bladder tumor (TURB) does not prevent unintended stimulation of the obturator nerve when electroresection is performed on the lateral wall of the bladder. It results in muscle contraction of the adductor muscles of the thigh, which may lead to perforation of bladder wall with the resectoscope loop. The aim of the...

1. The following nerves arise from the lumbar plexus; a. Lateral Cutaneous Nerve of the Thigh b. Obturator nerve c. Tibial nerve d. Saphenous nerve e. Sural nerve 2. Stimulation of hamstrings or knee flexion are acceptable motor responses using the PNS prior to LA injection. 3. Complications of Lumbar Plexus block include; a. Epidural block b. Sub arachnoid/intrathecal injection c. Cardiovascul...

INTRODUCTION Transurethral surgery has become the dominant treatment for bladder and prostatic tumours. Regional anaesthesia is the favoured anaesthetic technique but adductor spasm leading to bladder wall perforation and increased morbidity is not uncommon. This review seeks to outline the cause, risk factors predisposing to this complication and the various techniques that have been adopted t...

IN THE CURRENT ANATOMIC STUDY, SPECIAL ATTENTION WAS GIVEN TO THE RELATIONSHIP OF THE POSTERIOR DIVISION OF THE OBTURATOR NERVE TO SURROUNDING STRUCTURES: the obturator canal and the fibromuscular and vascular structures of the medial thigh region. These intimate relationships may, in certain conditions, constitute critical sites of entrapment of the posterior division of the obturator nerve an...

Obturator neuropathy is a difficult clinical problem to evaluate. One possible cause of pain is due to fascial entrapment of the nerve. Symptoms include medial thigh or groin pain, weakness with leg adduction, and sensory loss in the medial thigh of the affected side. Radiographic imaging provides limited diagnostic help. MRI may detect atrophy in the adductors of the leg. However, it is unable...

Femoral nerve lesions are uncommon, but very distressing at the functional level because of the absence of knee locking mechanism by the quadriceps muscle. We propose here a new neurotization procedure of obturator nerve motor branches to the motor portion of the femoral nerve in the thigh. This study was conducted on five cadavers. The motor portion of the femoral nerve and the motor branches ...

Objective To determine whether spinal anesthesia combined with obturator nerve blockade (SOB) is effective in preventing obturator nerve stimulation, jerking and bladder perforation during transurethral resection of bladder tumor (TURBT). Material and methods In this clinical trial, 30 patients were randomly divided into two groups: spinal anesthesia (SA) and SOB. In SA group, 2.5 cc of 0.5% ...

There are a number of puzzling circumstances related to the occurrence of the accessory obturator nerve and the innervation of the pectineus muscle. What is the frequency of occurrence of the nerve? What is its pattern of innervation? Does the pectineus muscle belong to the ventral or the dorsal division of the thigh musculature? Is its position in the ventral or the dorsal division reflected i...

Obturator nerve injury is a known injury after robot-assisted laparoscopic radical prostatectomy (RALP) and patients often present with motor and sensory deficits in the immediate postoperative period. We describe a 65-year-old male who presented with motor deficits, indicative of obturator neurapraxia after RALP upon waking from anesthesia. Work-up revealed an expansile hematoma possibly compr...
