- One arm if needed to keep by the side of the patient , the draw sheet should cover the arm as shown & tucked under the patient to prevent injury to brachial plexus
What is the Role of Autoantibodies in COVID-19? The angle may vary between 30 and 60 degrees depending on the uninjured tissues available at both ends of the horizontal line. Failure to completely perforate the fascia before medial direction of the needle out of the incision decreases the distance between the perforation point and the urethra (Fig. Clamps are applied to the uterine vessels at the level of the isthmus and may be sutured now or after cervical section. In addition to neurologic complications, which are discussed here, other complications that have been reported after procedures in the lithotomy position include lower extremity compartment syndrome, venous thrombosis, and rhabdomyolysis.101,102 The frequency of perioperative complications may increase with an exaggerated or “high” lithotomy position because the angle of the hips and lower extremities in this position is even more pronounced.103, Neurologic injuries related to the lithotomy position may affect the femoral, sciatic, and common peroneal nerves. Reitan Ribeiro, Audrey T. Tsunoda, in Principles of Gynecologic Oncology Surgery, 2018. Two parallel, 15-blade stab incisions are made above the pubic symphysis 1.5 cm from the midline (3 cm apart). Intrascrotal cysts and solid masses can be visualized and differentiated because cysts show a soft texture with liquid inside (Fig. Thomas, Liji. A total of 1170 patients, who were operated on in the lithotomy position, were evaluated retrospectively. Palpate the mass again, and fix the mass with left hands from the surgeon and the first assistant.

The patient should be prevented from slipping if Trendelenburg positioning is required. Endoscopic view of inflammatory changes of visceral layers of the tunica vaginalis. Pelvic examination 2. 1. A standard or modified lithotomy position may be elected based on surgical preference and concomitant procedures, with a supine pelvis-inclined (Trendelenburg) position recommended. 6.1.5–6.1.6). Endoscopic view of the caput epididymis. In addition, the patient may encounter difficulties with bowel movement because of gluteal contractures and cicatricial changes involving the anal opening. Placement of drainage strips. With palpation of the adductor longus muscle, the gracilis should be two to three fingerbreadths posterior. Some surgeons advocate a small shaving of the preserved cervix for a double margin check on final pathologic assessment. The major surgical instruments are the scrotoscopic equipment package, cystoscopic biopsy package, resectoscope, and absorbable sutures (4-0, 5-0). This incision, centered over the mid-urethra, may vary between 1.5 and 3 cm (Fig. 42-5). These include: In some conditions it is not advisable to adopt the lithotomy position, such as if there is an injury which prevents proper flexion or abduction of the hip joint. One soft pillow is given under head. 6.1.1). The genital region is routinely sterilized and draped. Dissect scrotal skin and muscles to the tunica vaginalis (see Chapter 4: General Techniques of Scrotoscopic Surgery for detailed descriptions). The sciatic nerve functions to provide cutaneous innervation to the foot and leg, as well as motor innervation of the biceps femoris (hamstring muscle), leg, and foot.107. Excessive stretching of the sciatic nerve by overflexion of the hip and extension of the knee during establishment of the lithotomy position or by shifting of the patient during the procedure may result in injury. 25.24). Figure 6.1.8. 42-6). The scrotal incision is then closed with one stitch. The height and abduction angle of the foot stools are not constant, especially for patients with spine or leg malformations. Because of illness or injury, some individuals cannot be examined in the conventional dorsal lithotomy position. 2019. Cystoscopy, also known as cystoureterography or prostatography, is an invasive diagnostic procedure that allows direct visualization of the urethra, urinary bladder, and ureteral orifices through the transurethral insertion of a cystoscope into the bladder. Fig. Figure 8.5.8. The patient lies with back flat on operating room bed. The cervix is gently pulled to prevent damage to the vascular supply originating from the IP ligaments to the uterus (Fig. The patient is placed in the dorsal supine modified lithotomy position with arms tucked securely to the patient's side. O Figs. Modifications of the lithotomy position include low, standard, high, hemi, and exaggerated based on how high the lower body is raised or elevated for the procedure. Resection of the cauda epididymis. If the procedure is performed without local anesthetic, a saline injection at the level of the mid-urethra, extending laterally, may be elected to aid in development of the plane of dissection between the vaginal epithelium and the periurethral fascia. Boluo Liang, ... Zhao Wang, in Scrotoscopic Surgery, 2019. In particular, investigators have suggested that excessive hip flexion in the lithotomy position may compress the nerve as it passes through the sciatic notch, thus potentially resulting in ischemic neuropathy.108,109 The potential sequelae of sciatic depend on the location of the insult along the course of the nerve. Bin Yan, ... Keqin Zhou, in Scrotoscopic Surgery, 2019. The transection can be performed with a cold scalpel or with the monopolar energy device in cut mode. The lithotomy position involves the positioning of an individual's feet above or at the same level as the hips (often in stirrups), with the perineum positioned at the edge of an examination table. 42-10). The dorsal lithotomy position is generally used for pelvic exams, because it provides for good access to pelvis while inspecting the vulva, inserting a vaginal speculum, and performing a bimanual exam. Fig. Please check with your facility’s guidelines but typically: Figure 8.5.7. This “pushing” maneuver minimizes disruption of the periurethral and endopelvic fascia. Injury to the thigh portion of the sciatic nerve, for example, results in difficulties with flexion of the leg, whereas disruption of the tibial nerve abolishes the ankle jerk reflex. 8.5.6). In this study, we assessed the incidence and risk factors associated with lower extremity neurapraxia in operations performed in the lithotomy position. Transuret… 42-2). 7.5.1 and 7.5.2). Indications for the lithotomy position are presented briefly below: Care should be taken to pad all points of contact between the lower limbs and the limb holders. Endoscopic view of chronic epididymitis. There has been recent light on the adverse events associated with the use of the lithotomy position. The lithotomy position is a variation of the supine position in which the hips are flexed, the legs abducted, and knees flexed. There are two types of cystoscopy: rigid and flexible.
