Antegrade Balloon Dilatation as a Treatment Option for Posttransplant Ureteral Strictures: Case Series of 50 Patients.
Experimental and clinical transplantation : official journal of the Middle East Society for Organ Transplantation, 2020Co-Authors: Liselotte S S Ooms, Adriaan Moelker, Joke I Roodnat, Jan N M Ijzermans, Turkan TerkivatanAbstract:The aim of this study was to investigate the effects of antegrade balloon dilatation on Ureteral Strictures that developed after kidney transplant. The hospital databases of the Erasmus Medical Center (Rotterdam, The Netherlands) and the Academic Medical Center (Amsterdam, The Netherlands) were retrospectively screened for patients who underwent balloon dilatation after kidney transplant. Balloon dilatation was technically successful whenever it was able to pass the Strictured segment with the guidewire followed by balloon inflation; the procedure was clinically successful if no further interventions (for example, surgical revision of the Ureteroneocystostomy or prolonged double J placement) were necessary. Fifty patients (2.4%) of 2075 kidney transplant recipients underwent antegrade balloon dilatation because of urinary outflow obstruction. Median time between transplant and balloon dilatation was 3 months (range, 0-139 mo). In 43 patients (86%), balloon dilatation was technically successful. In the remaining 7 patients (14%), it was impossible to pass the Strictured segment with the guidewire. In 20 of 43 patients (47%) having a technically successful procedure, the procedure was also clinically successful, with median follow-up after balloon dilatation of 35.5 months (range, 0-102 mo). We did not identify any patient or Stricture characteristic that influenced the outcome of treatment. Balloon dilatation is a good option for Ureter Stricture treatment after kidney transplant as it is minimal invasive and can prevent surgical exploration in almost 50% of cases.

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.
