Efficacy of ureterocalicostomy in treating secondary long-segment upper ureteral stricture

To evaluate the efficacy and safety of ureterocalicostomy for long-segment upper ureteral stricture.

A total of 13 patients underwent ureterocalicostomy for long-segment upper ureteral stricture, and a long-term follow-up was carried out to observe postoperative results, complications and renal function at 6 months after surgery.

Among the 13 patients undergoing ureterocalicostomy, 12 achieved successful results with surgery. Nine of the 12 received open surgery and 3 patients received laparoscopic surgery. During the perioperative period, 3 patients developed fever while 2 patients had hematuria and irritation in lower urinary tract, and all improved after symptomatic treatment. The 12 patients with successful surgeries achieved remission of hydronephrosis without anastomotic stricture. At 6 months after surgery, the 12 patients had significantly decreased serum creatinine and cystatin C levels and markedly increased estimated glomerular filtration rate, as compared with those before surgery (P<0.05).

Ureterocalicostomy is an effective, safe, optional treatment strategy for secondary long-segment upper ureteral stricture.
