Percutaneous nephrolithotomy in treatment of 64 cases of proximal ureteral calculi

Objective To evaluate the safety and efficacy of percutaneous nephrolithotomy(PCNL) in treating compact proximal ureteral calculi. Methods The data of 64 cases underwent percutaneous nephrolithotomy were reviewed and evaluated. Results The 64 cases of ureteral calculi were successfully treated with lithotripsy, the stone clearance rate was 100%. The average operation time was 45 minutes, the estimated blood loss was 40 ml, no serve complication such as massive haemorrhage, ureteral performation or conglutinant stenosis happened. The average hospitalization was 8 days. Two to three month follow-up was achieved in all patients with significant relief of hydronephrosis, no recurrence was found. Conclusions PCNL is a safe and effective method in managing compact proximal ureteral calculi. Key words: Precataneous nepnrolithotomy; Proximal ureteral calculi; Safety; Efficacy
