INTRODUCTION: Ureteral intussusception is a rarely reported condition, primarily as a complication of ureteric tumours.
Fewer than 30 case reports have been made. This case represents the first reported case, to our knowledge, of ureteral intussusception caused by a ureteric calculus.
PRESENTATION OF CASE: We present the case of a 70 year old man with a history of conservatively managed renal calculi, in whom obstructive ureterolithiasis was incidentally detected. Retrograde pyelography and ureteroscopy revealed intussusception of the ureter around a calculus. Extensive biopsies revealed no evidence of tumour, and the intussusception resolved following stone clearance.
DISCUSSION: Literature review of previously reported cases of ureteral intussusception revealed 26 cases, of which 22 were secondary to tumour and 4 were secondary to surgical procedures. We propose a mechanism by which calculus-related ureteral intussusception may occur, and suggest treatment for this condition.
CONCLUSION: Calculus-related ureteral intussusception is a rare condition, of which this represents the only case report. Management of the condition should involve excluding the presence of tumour, and then clearing the stone, avoiding the use of a basket for retrieval of fragments.
