"Lead Pipe" Ureter after Renal Transplantation

2012 Medical Connections  
Objective: To describe a case of "lead pipe" transplanted ureter. Case: A 16-year-old boy presented with a progressive increase in serum creatinine level and hydronephrosis 8 months after renal transplantation. An indwelling urethral catheter had not improved renal function. Following insertion of a nephrostomy tube, the creatinine level normalized. Antegrade pyelography demonstrated slow passage of contrast material through the ureter with no stricture. Result: Treatment consisted of

Conclusion: This is the first reported case of a "lead pipe" transplanted ureter in a child, probably caused by ischemia. Clinicians should be alerted to this possibility in pediatric renal transplant recipients with rising serum creatinine and progressive hydronephrosis, even in the absence of imaging findings of obvious obstruction.
