ABSTRACT
One hundred and fifty patients with impacted upper-ureteral calculi were treated with ureteroscopic lithotripsy (URSL group,n =58),percutaneous nephrolithotomy (PCNL group,n =42) or retroperitoneal laparoscopic ureterolithotomy (RPLU group,n =50) from April 2011 to August 2015.The operative time,length of postoperative hospital stay,stone-free rate and the incidence of postoperative complications were observed and compared among three groups.The stone-free rate of URSL group one month after surgery was 77％,which was significantly lower than PCNL (95％) and RPLU groups (100％) (P ＜ 0.05).But the operative time and length of postoperative hospital stay of URSL group [(37.2 ± 5.6)min,(3.9-±0.8)d] were significantly shorter than PCNL group[(75.2 ±6.7) min,(7.9 ±0.9))d] and RPLU group [(65.3 ± 6.1) min,(8.7 ± 0.9) d] (all P ＜ 0.05).The postoperative complication rates of three groups were 8％,10％ and 10％,respectively.
ABSTRACT
The clinical data of 42 patients with impacted upper-ureteral calculi undergoing retroperitoneal laparoscopicureterolithotomy(RPLU)from January 2008toDecember 2010 were retrospectively analyzed.RPLU was successfully performed in 40 cases,and simultaneous laparoscopic electrocoagulation ablation was also performed in 11 cases complicated with ureteral inflammatory polyps.No massive bleeding occurred during the operations.The stone-free rate 3 d after operation was 100％,and no stone left as reviewed by kidney ureter bladder X-ray (KUB) and B-ultrasonography.During the follow-up of 3 to 24 months (mean 11 months),40 cases showed no stone recurrence and no ureteral stricture in KUB and B-ultrasonography.The hydronephrosis of all RPLU patients relieved.Results indicate that RPLU is a safe and effective minimally invasive operation for treatment of impacted upper-ureteral calculi.
