Robotic-assisted laparoscopic dismembered pyeloplasty.

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Laparoscopic pyeloplasty success rates are comparable to open surgery.
• The learning curve for laparoscopic pyeloplasty has limited its widespread adoption.
• Robotic assistance may enhance precision in dissection and suturing during laparoscopic pyeloplasty.

Purpose of the Study:

• To assess the feasibility and efficacy of robotic-assisted laparoscopic pyeloplasty.
• To evaluate robotic assistance in overcoming challenges in laparoscopic pyeloplasty.

Main Methods:

• 50 patients underwent robotic-assisted laparoscopic dismembered pyeloplasty using a four-trocar technique.
• Postoperative assessment included renograms to evaluate ureteropelvic junction patency and renal function.
• Patients were discharged early, with stent removal at approximately 3 weeks.

Main Results:

• All procedures were successful without open conversion or transfusion, with minimal blood loss (avg. 40 mL).
• Average operative time was 122 minutes, with anastomosis taking an average of 20 minutes.
• Short hospital stays (avg. 1.1 days) and good short-term outcomes were observed, with 96% demonstrating stable renal function and improved drainage on renograms.

Conclusions:

• Robotic-assisted laparoscopic pyeloplasty is a feasible and effective minimally invasive approach for ureteropelvic junction reconstruction.
• The technique shows promise for improving outcomes and potentially reducing the learning curve for laparoscopic pyeloplasty.
