ABSTRACT
Objective To evaluate the surgical techniques and clinical applications of single-port transumlilical laparoscopic dismembered pyeloplasty for the treatment of ureteropelvic junction obstruction (UPJO). Methods From August 2009 to March 2010, 15 patients were treated with single-port transumbilical laparoscopic dismembered pyeloplasty. There were 12 males and 3 females,aged 12 to 55 years with an average age of 20 years, who were diagnosed by diuretic renography,IVU, and MRU et al. A single umbilical incision of 3. 5cm was made for single-port trocar and a flexible-tip 0°digital video-laparoscope was used in all cases. The procedures were performed according to the methods used in classical laparoscopic dismembered pyeloplasty with general instruments. ResultsAll operations were performed successfully without conversion to open surgery. The mean operative time was 90 (75-145) min, and the mean hospital stay length was 6 days. No organs injury occurred during operation, and no urine leakage was found afer operation. The symptoms of low back pain disappeared and hydronephrosis reduced apparently or dispeared without any anastomotic stenosis after follow-up of 4-6 months. Conclusions Single-port transumbilical laparoscopic dismembered pyeloplasty is feasible, effective and safe for the treatment of UPJO.
