Laparoscopic pelvilithotomy combined with percutaneous nephrolithotomy surgery treatment in multiple renal calculi / 中国综合临床

ABSTRACT

Objective To study the key points and preliminary experience in the application of laparoscopic pelvilithotomy combined with percutaneous nephrolithotomy(PCNL)surgery in multiple renal calculi. Methods Eight patients,accepted laparoscopic pelvilithotomy combined with PCNL surgery in our hospital from January 2008to December 2009,were enrolled into the study. Retroperitoneal approach were performed in all operations. The biggest stone was 3.3 cm ×2.3 cm,the smallest one was 0.5 cm ×0.5 cm. All patients had renal pelvis cast stone along with multiple small renal calyceal stones. The stones were removed under laparoscopic operation at the first step. If it was difficult to remove the pelvis cast stone,nephroscope were settled into the pelvis through incision,and then the shattered stone smashed by lithotripsy were removed under the observation of nephroscope. Further exploration and removal of the remaining stones in every calices was necessary for the patients. Results The operations were successful in all cases and all stones were removed thoroughly and get satisfactory effects. The average operation time was 90 minutes. No serious complications happened,such as bleeding,urine leakage or ureteral stricture. The average length of hospital stay was 5 days. Conclusions Our treatment combines the advantages of both laparoscopic pelvilithotomy and percutaneous nephrolithotomy to reduce the incidence of complications and improve the therapeutic effects.
