Full-length ureteral avulsion caused by ureteroscopy: report of one case cured by pyeloureterostomy, greater omentum investment, and ureterovesical anastomosis.

The aim of this report was to look for a good solution to full-length ureteral avulsion. This report retrospectively analyzed the data of the patient. The patient underwent ureteroscopic management. Full-length avulsion of ureter occurred during ureteroscopy. Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis were performed immediately. The patient was followed-up 25 months. After the first operation, the patient developed hydronephrosis because of press of fibrosis tissue outside ureter and anastomotic atresia of ureter-bladder. When we finished the second operation, the renal function recovered well. Full-length avulsion of ureter is a severe complication. Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis are probably a good choice.
