Ureter Injury as a complication of oblique lumbar interbody fusion
World Neurosurgery, 2017Co-Authors: Hyeongjin Lee, Jinsung Kim, Kyeongsik Ryu, Choonkeun ParkAbstract:Background Oblique lumbar interbody fusion is a commonly used surgical method of achieving lumbar interbody fusion. There have been some reports about complications of oblique lumbar interbody fusion at the L2–L3 level. However, to our knowledge, there have been no reports about Ureter Injury during oblique lumbar interbody fusion. We report a case of Ureter Injury during oblique lumbar interbody fusion to share our experience. Case Description A 78-year-old male patient presented with a history of lower back pain and neurogenic intermittent claudication. He was diagnosed with spinal stenosis at L2–L3, L4–L5 level and spondylolisthesis at L4–L5 level. Symptoms were not improved after several months of medical treatments. Then, oblique lumbar interbody fusion was performed at L2–L3, L4–L5 level. During the surgery, anesthesiologist noticed hematuria. A retrourethrogram was performed immediately by urologist, and Ureter Injury was found. UreteroUreterostomy and double-J catheter insertion were performed. The patient was discharged 2 weeks after surgery without urologic or neurologic complications. At 2 months after surgery, an intravenous pyelogram was performed, which showed an intact Ureter. Conclusions Our study shows that a low threshold of suspicion of Ureter Injury and careful manipulation of retroperitoneal fat can be helpful to prevent Ureter Injury during oblique lumbar interbody fusion at the upper level.

delayed Ureter stricture and kidney atrophy after oblique lumbar interbody fusion
World Neurosurgery, 2020Co-Authors: Sun Geon Yoon, Soon Chan KwonAbstract:Background Oblique lumbar interbody fusion (OLIF) is a surgical technique for lumbar interbody fusion that allows surgeons to use a large cage while preserving the spine muscles. The surgical corridor of OLIF is close to the Ureter in the retroperitoneal space and therefore entails a potential for Injury to this organ. Although there are some published cases of Ureteral Injury that were identified during OLIF, to our knowledge, there have been no reports about delayed Ureteral strictures and kidney atrophy after OLIF. We report a case of Ureter stricture and ipsilateral kidney atrophy that was incidentally identified a few months postoperatively without signs of Ureter Injury during the operation. Case Description A 49-year-old woman presented with low back and right leg pain. On lumbar magnetic resonance imaging, a Meyerding grade 1 spondylolisthesis of L4 on L5 with L4 nerve root encroachment was confirmed. The patient underwent L4/L5 OLIF and was discharged on the 10th day after surgery with improved symptoms. Three months later, an abdominopelvic computed tomography performed for an unrelated condition showed left kidney atrophy. A retrograde Ureteropyelogram confirmed a stricture near the operation site. A Ureter stent was successfully inserted to overcome the stricture, but renal atrophy was not reversed. Conclusions Ureter Injury may be observed with several months' delay after OLIF in patients without symptoms or laboratory abnormalities, even if no direct Injury was noted during the procedure.
