Laparoscopic anatrophic nephrolithotomy for managing large staghorn calculi

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrolithotomy

Background:

• Large staghorn renal calculi pose a surgical challenge.
• Percutaneous nephrolithotomy may not be suitable for all cases.
• Open anatrophic nephrolithotomy is a traditional but invasive approach.

Purpose of the Study:

• To evaluate the efficacy of laparoscopic anatrophic nephrolithotomy.
• To assess its safety and outcomes for managing large staghorn renal calculi.
• To compare it as an alternative to open surgery.

Main Methods:

• Laparoscopic transperitoneal anatrophic nephrolithotomy was performed in five patients.
• The procedure mimicked open anatrophic nephrolithotomy, with renal artery clamping.
• Nephrotomy incision and closure techniques were detailed; intraoperative ultrasonography was used in later cases.

Main Results:

• Mean stone size was 53 mm; mean operative time was 170 minutes.
• No blood transfusions were required; all procedures were uneventful.
• Minor residual stones in two patients were managed with shock wave lithotripsy; all patients showed improved renal function.

Conclusions:

• Laparoscopic anatrophic nephrolithotomy is a viable alternative for selected patients.
• It provides a minimally invasive approach with an acceptable stone-free rate.
• Further studies are needed to establish it as a preferred method.
