The obliterated ureteric orifice: a nightmare for the pelvic surgeon or a routine-job for the endo-urologist? Case report of a standardized endoscopic approach

We present the endoscopic management of two cases of complete ureteric occlusion at vesico-ureteral junction (VUJ) level following iatrogenic injury. Case 1 is a 60-year-old man who developed bilateral ureteric injury at the level of the VUJ following robot-assisted radical prostatectomy (RARP) for Gleason 3 + 4 = 7 T2bN0 prostate cancer. Case 2 is an 81-year-old man with history of recurrent G2pTa transitional cell carcinoma of the bladder originally diagnosed in 2005 and history of radical radiotherapy for prostate cancer. At his most recent transurethral resection of bladder tumour, the left ureteric orifice was not visualized. We describe step-by-step our technique in restoring continuity of the ureter with minimally invasive endoscopic approach, resulting in excellent long-term upper tract drainage for our patients. To our knowledge, combined utilization of a Collins knife to incise the area around the ureteric orifice to unearth them is not reported. We aim to report our technique and its outcomes.
