Emergency treatment of obstructive acute renal failure by means of endoscopic manipulation (report of 23 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate endoscopic manipulation such as ureteroscopy,air pressure lithotripsy and double J catheter placing for the emergency treatment of obstructive acute renal failure (OARF). Methods 23 cases of obstructive acute renal failure,with an average age of 53,were treated by instant endoscopic manipulation.Blood uria nitrogen (BUN) before treatment was 16.1～55.6 mmol/L and serum creatinine (SCr) 465～2 099 ?mol/L.The patients were followed up for 1～9 months. Results Satisfactory result has been observed in all. 24 h urine output reached 2 400～5 600 ml with BUN and SCr dropped significantly.Normal renal function has been regained in 19 whereas SCr dropped to 200 ?mol/L in the other 4 patients. Conclusions Endoscopic management has the advantages of minimal invasion,safety,quick recovery and bilateral ureteral obstruction could be dealt with simultaneously.Instant endoscopic management plays an important role in the treatment of obstructive acute renal failure.
