Abstract:
Objective To investigate the advantages of emergent ureteroscopy for the treatment of acute obstructive renal failure resulted from upper ureteral calculi.Methods A total of 123 cases of acute renal failure caused by bilateral upper ureteral calculi was treated with ureteroscopic exploration,ballistic lithotripsy,catheter indwelling,and percutaneous nephrolithotomy.Results The serum BUN(blood urea nitrogen) and Cr(creatinine) were decreased to normal levels 2～10 days after operation in 100 cases(81.3%);the levels of Cr were maintained at 188.6～232.3 ?mol/L 10～15 days after operation in 22 cases.In 1 case of congenital solitary kidney(renal failure caused by chronic contralateral ureteral calculous obstruction),a hemodialysis was needed on the 3rd day after operation,and the serum Cr was 810 ?mol/L on the 15th day after operation and was dropped to normal after 2 months postoperatively.In 4 cases of previous unilateral nephrectomy or congenital solitary kidney,azotaemia remained at 3 months after operation.Conclusions Emergent ureteroscopy for acute renal failure caused by calculous obstruction possesses advantages of immediate obstruction relief,effective renal function protection,little trauma,low complication rate,and simple performance.
