Abstract:
Objective To discuss a modified laparoscopic pyeloplasty. Methods A total of 32 patients presenting ureteropelvic junction obstruction underwent a modified laparoscopic pyeloplasty which included the dissection of the ureteropelvic junction under laparoscope and the pyeloplasty through an extended trocar-incision 2.5~3 cm in length as open surgery did. Results The operation was successfully completed in all the 32 patients.Intraoperative findings demonstrated renal inferior polar compression by ectopic blood vessels in 1 patient and primary ureteropelvic stricture in 31 patients.The operative time was 40~70 min(mean,52 min) and the intraoperative blood loss was 20~30 ml(mean,23 ml).No surgery-related complications were observed.Follow-up checkups in 27 patients for 7~15 months(mean,9.6 months) showed disappearance of lumbar distending pain.Intravenous pyelography revealed no anastomotic obstruction.In 17 patients presenting the separation of the renal collective system,(B-ultrasonography) revealed a decrease from 2.0~4.2 cm(mean,2.8 cm) preoperatively to 1.0~2.3 cm(mean,1.5 cm) postoperatively.Conclusions The modified laparoscopic pyeloplasty simplifies the operation performance and shortens the operation time.
