Abstract
We present the first reported case of calculus-related ureteral intussusception.
We examine the literature regarding other causes of ureteral intussusception.
We provide an hypothesis for the development of calculus-related intussusception.
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.
