  • Ureteropelvic junction obstruction is a fairly common diagnosis in urology. With the emergence of robotic surgery in urology, complex ureteral reconstruction of the proximal, mid, and distal ureter is being undertaken with robotic assistance with excellent results. We present the case of a 61-year-old male who presented with an atypical partial ureteropelvic junction obstruction. The etiology was suspected to be from external compression of the proximal ureter by a calcified periureteral mass. The mass was theorized to be secondary to occult ureteral perforation and extraluminal migration of a renal calculus during repeat percutaneous nephrolithotomy (PCNL)/ shock wave lithotripsy (SWL). The patient ultimately underwent surgical treatment and we describe the technique of robotic assisted laparoscopic excision of the periureteral mass and proximal ureter with ureteropyelostomy. He sustained no immediate complications and had excellent short term results from his operation.
