ABSTRACT
Objective To evaluate the clinical feasibility of grading of ureteral stricture in renal allograft.Methods The clinical data of 9 case of ureteral stricture after renal transplantion from February 2015 to September 2015 were retrospectively analyzed and relative articles were reviewed to evaluate the significance of ureteral stricture grading.The diagnosis of ureteral stenosis was made by serum creatinine elevation,ultrasound of allograft kidneys and presence of stricture on a pyelogram.Grade 1 ureteral stenosis was defined as graft function deterioration with presence of hydronephrosis on ultrasound,but no obvious stricture identified on a pyelogranm.Grade 2 was defined as serum creatinine elevation,presence of hydronephrosis on ultrasound,and a focal (<1 cm) distal ureteral stricture at the ureteral anastomotic site on a pyelogram.Grade 3 was defined as serum creatinine elevation,hydronephrosis on ultrasound,and a long segment (>1 cm) distal ureteral stricture extending to proximal ureter or pelvis on pyelogram.Results One case,6 cases and 2 cases were classified to grade 1,2 (stricture length <1 cm) and 3 (>1 cm),respectively.One case of grade 1,6 cases of grade 2 and 1 case of grade 3 were successfully dilated by balloon dilation catheter and endoureterotomy.One case of grade 3 was converted to open reconstructive surgery.Surgery success rate of grade 1 and 2 was 100% (7/7) and 100% (6/6) 6 and 9 months after surgery,respectively.Ureteral stenosis did not recur in one case of grade 1 and 6 cases of grade 2 during a follow-up period of 12 months after surgery.However,one case of grade 3 reoccurred 6 months after surgery,and reoperation was performed and there was no recurrence up to now (10 months).Conclusion Wuzhi tablet acted as an effective agent that makes rifampicin containing anti-tuberculosis chemotherapy possible and safe by stabilizing blood concentration of tacrolimus in post-renal transplant tuberculosis patients,which also reduced the dosage of tacrolimus as well as the risk of acute rejection greatly.
