Objectives:
We developed minimal incision-assisted retroperitoneoscopic surgery (MARP) in an attempt to pursue optimized patient-related benefits. We evaluated the clinical value of MARP for upper urinary tract diseases compared with pure retroperitoneoscopic surgery (PRPS).
Patients And Methods:
Between January 2003 and September 2008, PRPS and MARP were carried out in 338 and 85 patients, respectively. The upper urinary tract surgical procedures were defined as simple and complex procedures. We defined our experience from January 2003 to December 2005 as our early stage of PRPS learning curve. Our experience from January 2006 to September 2008 was defined as our late stage of PRPS learning curve. Patients' perioperative details were compared.
Results:
MARP was associated with shorter operative time for each complex procedure and with less frequent conversion to open surgery (2.4% vs. 11.3%, p = 0.023). A significantly greater proportion of MARP patients underwent complex procedures (81.2% vs. 49.1%, p < 0.001), and a significantly greater proportion of MARP were carried out at the early stage of PRPS learning curve (62.4% vs. 44.1%, p = 0.003). Estimated blood loss, hospital stay, the amount of analgesic use (diclofenac sodium suppository), and intraoperative and postoperative complications were comparable.
Conclusions:
MARP maintains the patient-related benefits of PRPS while allowing surgeons to perform more complex cases of upper urinary tract diseases and shortening the relevant operative time. It can be useful for cases in which the specimen is going to be extracted intact, when starting out learning retroperitoneoscopy, or when unable to progress the case using laparoscopic techniques.
Insights
Minimal incision-assisted retroperitoneoscopic surgery (MARP) offers advantages over pure retroperitoneoscopic surgery (PRPS) for complex upper urinary tract procedures. MARP reduces operative time and conversion rates, enhancing surgical capabilities.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Surgical Innovation
Background:
- Retroperitoneoscopic surgery is a key minimally invasive approach for upper urinary tract diseases.
- Optimizing patient outcomes and expanding procedural complexity in retroperitoneoscopy remains an ongoing goal.
Purpose of the Study:
- To introduce and evaluate the clinical value of minimal incision-assisted retroperitoneoscopic surgery (MARP).
- To compare MARP with pure retroperitoneoscopic surgery (PRPS) for upper urinary tract diseases.
Main Methods:
- A comparative study involving 338 patients undergoing PRPS and 85 patients undergoing MARP between January 2003 and September 2008.
- Surgical procedures were categorized as simple or complex.
- Perioperative details were collected and analyzed.
Main Results:
- MARP demonstrated a shorter operative time for complex procedures and a significantly lower conversion rate to open surgery (2.4% vs. 11.3%).
- A higher proportion of MARP patients underwent complex procedures (81.2% vs. 49.1%).
- Blood loss, hospital stay, analgesic use, and complication rates were comparable between the groups.
Conclusions:
- MARP preserves the patient benefits of PRPS while enabling surgeons to manage more complex upper urinary tract cases.
- MARP is beneficial for procedures requiring intact specimen extraction, for surgeons learning retroperitoneoscopy, and for challenging laparoscopic cases.
