However, both often require general anesthesia, which can be problematic for a predominantly elderly population with multiple co-morbidities. Here we describe an endoscopic technique of ureteral meatotomy to not only predictably allow for reflux of intravesical agents through the ureter, but also to allow upper tract endoscopy to be performed in the office setting. METHODS: From 2015-2021, we performed ureteral meatotomy on 10 patients. All patients who underwent this procedure had upper tract urothelial tumors deemed suitable for primary endoscopic management, based on patient’s clinical characteristics; tumor number; size; location; and/or biopsy grade.Under general anesthesia, a 10 F dual lumen ureteral catheter or 6-12 F Nottingham dilator was inserted into the distal ureter in order to allow for alignment of the ureter towards the bladder neck and to ensure the orifice is incised in the correct direction. Using either a Holmium laser or Collin’s knife, a full-thickness 2 cm incision was made on the distal intramural ureter at the 12 o’clock position, until the anterior portion of the catheter was visualized. Intraoperative cystogram was used to confirm ureteral reflux. A double J stent was then left in place for 3 weeks for mucosal healing and reshaping of the distal ureteral segment. Postoperatively, patients underwent 6 cycles of mitomycin, either via indwelling Foley catheter or nephrostomy tube. Lower and upper urinary tract surveillance was performed using flexible cystoscope and/or ureteroscope in the office every 3-6 months for the first two years and annually thereafter. RESULTS: 10 patients with average age of 77 years, 40% of whom were male, underwent ureteral meatotomy between 2015 and 2021. 90% of tumors were either in the distal ureter or UPJ/renal pelvis. Average tumor size was 1.6 cm. 70% of tumors were low grade on biopsy. 3 patients had concomitant bladder cancer. There were no complications associated with chemotherapy instillation. Of the patients who had only upper tract disease, none developed a new recurrence in the bladder. CONCLUSIONS: We describe a novel anterior intramural ureteral incision technique in patients with ureteral tumors managed endoscopically that reliably allows for both chemotherapy administration and upper tract surveillance in an office setting.
