Urinary leakage after laparoscopic radical prostatectomy: a systematic review

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Anastomotic leakage is a potential complication following radical prostatectomy.
• Laparoscopic radical prostatectomy (LRP) is a common surgical approach.
• Understanding factors influencing leakage is crucial for patient outcomes.

Purpose of the Study:

• To systematically review the literature on the definition and incidence of anastomotic leakage after LRP.
• To investigate the relationship between leakage and surgeon experience, suture type, and surgical approach.

Main Methods:

• A systematic literature review was conducted using MEDLINE, Embase, and Cochrane Library.
• Included original papers with ≥30 patients and reported leakage rates.
• Data on leakage definition, incidence, and risk factors were extracted.

Main Results:

• 24 observational studies were included; no randomized controlled trials were found.
• Anastomotic leakage incidence averaged 9.7% (range 3.2%–33%), with varied definitions.
• No studied risk factors, including surgeon experience, reached statistical significance.

Conclusions:

• Evidence regarding urine leakage after LRP is limited and of poor quality.
• A lack of standardized definitions for leakage complicates comparisons.
• Further standardization is needed for robust meta-analysis and clinical guidance.
