This International Society for the Advancement of Spine Surgery statement has been generated to respond to growing requests for background, supporting literature and evidence, and proper coding for restorative neurostimulation for chronic low back pain. Chronic low back pain describes the diverse experience of a significant proportion of the population. Conservative management of these patients remains the predominant care pathway, but for many patients, symptom relief is poor. The application of new techniques in patients who have exhausted traditional care paradigms should be undertaken with a detailed understanding of the pathology being treated, the mechanisms involved, and the data supporting efficacy. This statement on restorative neurostimulation places this technology in the context of the current understanding of the etiology of mechanical low back pain and the currently available evidence for this technique. In an appropriately selected cohort with a specific subset of chronic low back pain symptoms, this technique may provide benefit to payers and patients.

Due to its ultraminimally invasive nature, endoscopic spinal surgery is an attractive tool in spinal oncologic care. To date, there has been no comprehensive review of this topic. The authors therefore present a thorough search of the medical literature on endoscopic techniques for spinal oncology. A systematic review using PubMed was conducted using the following keywords: endoscopic spine surgery, spinal oncology, and spinal tumors. Collectively, 19 cases described endoscopic spine surgery for spinal oncologic care. Endoscopic spine surgery has been employed for the care of patients with spinal tumors under the following 4 circumstances: (1) to obtain a reliable tissue diagnosis; (2) to serve as an adjunct during traditional open surgery; (3) to achieve targeted debulking; or (4) to perform definitive resection. These cases employing endoscopic techniques highlight the versatility of this approach and its utility when applied to the right patient and with an experienced surgeon. Our systematic review suggests that, given the right patient and an experienced surgeon, endoscopic spine surgery should be considered in the armamentarium for spinal oncologic care for both staging and definitive resection. This systematic literature review showed that endoscopic techniques have been successfully applied across the spectrum of care in spinal oncology, from diagnosis to definitive treatment.

ABSTRACTIntroduction:Ureteroceles present a diagnostic and treatment challenge in adults (1). With an estimated prevalence of 1/500 to 1/4000, it is not uncommon for any urologist to encounter ureteroceles in clinical practice (2). The incidence of prolapsed ureteroceles in adults is unknown (3).Materials and Methods:We present an interesting case of a 53-year-old male with a 20-year history of obstructive voiding symptoms who presented with urinary retention with a Foley catheter in place. Pre-operative evaluation included a transrectal ultrasound of the prostate which revealing prostate volume of 20cc. Urodynamics revealed a high-pressure, low flow voiding pattern with a functional detrusor muscle. Cystourethroscopy was performed revealing an orthotopic ureterocele on the left side that was prolapsed into the prostatic urethra, and the bladder neck was elevated. The patient then underwent holmium laser ureterocele excision with transurethral incision of the prostate (TUIP). Using MOSES technology and laser settings of 30Hz and 1.5J, the ureterocele was completely excised and a TUIP was performed.Results:The patient was discharged home on the day of surgery with a Foley catheter in place. On post-operative day 1 he passed a voiding trial with a post-void residual volume of 25cc. Renal ultrasonography was performed 3 months postoperatively revealing no hydronephrosis. His postoperative International Prostate Symptom Score of 2 was improved compared to his preoperative score of 34.Conclusion:Holmium laser ureterocele excision with a TUIP is an effective treatment modality in the management of a prolapsed orthotopic ureterocele causing bladder outlet obstruction in a male patient.
