Urine Leak After Kidney Transplant: A Review of the Literature.

Although they are not common, urologic complications after renal transplant are associated with risk of graft loss. Fluid collection during the postoperative period can be caused by urine leak or lymph leak of seroma. Biochemical analysis of the drained liquid is essential and should be compared with a concomitant serum sample. Surgical exploration is indicated if suspected urine leak is significant. Reimplantation of the ureter to the bladder can be challenging if there is extensive ureteral necrosis due to compromised vascularization.
