Retroperitoneal laparoscopic pyelolithotomy in the treatment of intrarenal pelvic calculi / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the clinical efficacy and safety of retroperitoneal laparoscopic pyelolithotomy in the treatment of intrarenal pelvic staghorn calculus or multiple renal calculi. Methods Fifteen patients(9 males and 6 females)with average age of 40 years old were treated. The diameters of the calculi were from 1.5 cm to 3.7 cm. Three trocars were used in this procedure as rou-tine. The renal sinus was exposed by separating the pelvis from outside to inside until reaching the in-fundibulum of the renal calyx. Then the renal calyx was cut open and the calculus was taken out. Double J stent was placed in the ureter and the incision of pelvis was closed by 3-0 absorbable suture. The drainage tube was pulled out 3-4 d post-operatively according to the drainage quantity. Double J stent was then pulled out 2 weeks after surgery. Results All the 15 procedures were successfully completed. The average operation time was 170 min and the average post-operative hospital stay was 7 d. During the 3-15 months' follow-up, 2 patients had calculus remnants with the size of 0. 2-0.5cm in diameter. Conclusions Retroperitoneal laparoscopic pyelolithotomy provides a minimally inva-sive treatment option in patients with intrarenal pelvic staghorn calculus or multiple renal calculi. It has the advantages of good exposure, little bleeding, small incision and fast recovery.
