Introduction: In posterior urethroplasty, exposure of the proximal urethral stump is the most important step that determines surgical outcome. However, this is sometimes difficult due to deviation of the prostate or overlying scar tissue. We present a novel preoperative simulation and intraoperative navigation method for this step.
Case Presentation: Three patients underwent excision and primary anastomosis for posterior urethral disruption after pelvic fracture. Preoperatively, volume-rendering image of the posterior urethra was constructed from gadolinium-enhanced magnetic resonance image, enabling simulation from the viewpoint of the operator in all three cases. Intraoperative navigation was performed in two patients by using transrectal ultrasound, visualizing the acoustic shadow of a cystoscope inserted into the prostatic urethra via the cystostomy tract. The overlying scar tissue was removed toward the urethral stumps identified by navigation. Urethroplasty was successful in all three patients.
Conclusion: The present methods were useful for precise identification of the proximal urethral stump.

Lateral lumbar interbody fusion(LLIF), including extreme lateral interbody fusion(XLIF) and oblique lateral interbody fusion(OLIF), constitute a treatment option for many lumbar disorders that predominantly cause degenerative disc disease. LLIF is beneficial for managing conditions, such as lumbar spondylolisthesis, degenerative disc disease, and adult spinal deformities. LLIF is preferred for enabling indirect decompression of the spinal canal and nerve root foramen, without inducing immediate postoperative damage to the peri-vertebral tissues.

Introduction: Robotic-assisted total knee arthroplasty (TKA) platforms require tibial and femoral pins to support rigidly fixed navigation arrays. These pins can be placed inside or outside the primary incision. We sought to compare 90-day complication rates between three different pin configurations: all-outside, intra-incisional femur/extra-incisional tibia, and all-inside.

In vivo optical imaging holds great potential for surgical guidance with the ability to intraoperatively identify tumor lesions in a surgical bed and navigate their surgical excision in real time. Nevertheless, its full potential remains underexploited, mainly due to the dearth of high-performance optical probes. Herein, hybrid cell membrane-biomimetic near-infrared II surface-enhanced Raman spectroscopy (NIR-II SERS) probes are reported for intraoperative resection guidance of orthotopic glioblastoma.

The widespread adoption of high-resolution computed tomography (CT) screening has led to increased detection of small pulmonary nodules, necessitating accurate localization techniques for surgical resection. This review examines the evolution, efficacy, and safety of various localization methods for small pulmonary nodules. Studies focusing on localization techniques for pulmonary nodules ≤30 mm in diameter were included, with emphasis on technical success rates and complication profiles.

Background: Supratentorial function-eloquent brain tumour surgeries challenge the balance between maximal tumour resection and preservation of neurological function. This study aims to evaluate the efficacy of preoperative and intraoperative mapping techniques on resection outcomes and post-operative deficits.
Methods: This systematic review and meta-analysis examined literature up to March 2023, sourced from PubMed, Embase, and Medline.
