Upper Ureteric Stricture Secondary to Celiac Plexus Block Managed by Robotic Ureterocalicostomy.

Introduction: Ureterocalicostomy is a well-established procedure of choice for recurrent pelviureteric junction (PUJ) obstruction refractory to endoscopic management, failed pyeloplasty, completely intrarenal pelvis, and iatrogenic upper ureteral stricture with significant peripelvic fibrosis. Robotic ureterocalicostomy is the procedure of choice in such scenarios where meticulous dissection and accurate anastomotic suturing is required. Case Presentation: We report the case of an 18-year-old male, who underwent celiac plexus block for pain management of chronic calcific pancreatitis and presented with pain in the epigastric region and the right flank. A CT and subsequent nephrostogram revealed an upper ureteral defect (corrosive stricture) of ∼4 cm at the level of PUJ. Robotic ureterocalicostomy was performed. We discuss the clinical presentation, evaluation, and management along with literature review. Conclusion: Iatrogenic ureteral strictures are not uncommon in urological practice, but an upper ureteral stricture secondary to celiac plexus block is a rarity. Adequate evaluation and timely intervention by reconstructive surgery, robotic ureterocalicostomy in this case, yield satisfactory results.
