Renal and Adrenal Minilaparoscopy: A Prospective Multicentric Study

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Minilaparoscopy (ML) involves using 3-mm instruments and laparoscopes for surgical procedures.
• The application of ML in renal and adrenal surgeries requires further investigation regarding its safety and efficacy.
• Identifying predictive factors for complications is crucial for optimizing patient outcomes.

Purpose of the Study:

• To evaluate the role and outcomes of contemporary minilaparoscopy in renal and adrenal surgeries.
• To identify predictors of complications in patients undergoing ML for these procedures.

Main Methods:

• A prospective multicenter study involving 110 patients from 6 Spanish centers.
• Procedures were performed using a standard ML approach with 3-mm trocars, laparoscope, and instruments.
• Data were collected prospectively, and statistical analysis was used to identify complication predictors.

Main Results:

• The study included various renal surgeries (nephrectomies, partial nephrectomies, nephroureterectomies, pyeloplasties, pyelolithotomies) and adrenalectomies.
• Overall complication rates were 5% intraoperatively and 8% postoperatively (Clavien II-IV).
• Mean operative time was 180 minutes, with excellent pain control and cosmetic outcomes observed.

Conclusions:

• This prospective series demonstrates that ML for renal and adrenal surgeries is safe and effective.
• Clinical outcomes and safety are not compromised despite potentially longer operative times compared to standard laparoscopy.
• ML offers significant advantages in terms of patient pain control and cosmetic results.
