Laparoscopic vs. Open nephrectomy for inflammatory renal conditions: a meta-analysis emphasizing safety

Area of Science:

• Urology
• Surgical Oncology
• Nephrology

Background:

• Nephrectomy is often required for inflammatory renal conditions (IRCs).
• Surgical approach (laparoscopic vs. open) may impact patient outcomes.
• Laparoscopic nephrectomy (LN) and open nephrectomy (ON) present distinct challenges and benefits.

Purpose of the Study:

• To compare the safety and efficacy of laparoscopic nephrectomy (LN) versus open nephrectomy (ON) for treating adult patients with IRCs.
• To evaluate perioperative outcomes, including complication rates, blood loss, and hospital stay.
• To determine if LN offers a safer alternative to ON in managing conditions like xanthogranulomatous pyelonephritis (XGP), pyonephrosis, and renal tuberculosis.

Main Methods:

• Systematic review and meta-analysis adhering to PRISMA and Cochrane guidelines.
• Inclusion of studies directly comparing LN and ON in adult patients with IRCs, focusing on perioperative outcomes.
• Exclusion of pediatric cohorts and studies that did not clearly differentiate between converted LN cases and ON groups.

Main Results:

• Analysis of 13 studies involving 868 patients revealed LN was associated with a significant 28% reduction in overall complications compared to ON (RR=0.72, p=0.0004).
• LN demonstrated a significant reduction in blood transfusions (53%, RR=0.47, p<0.0001) and blood loss, particularly in XGP patients (MD=-130.8 mL).
• Patients undergoing LN experienced shorter hospital stays (PMD=-3.04 days, p<0.00001) but longer operative times (PMD=+39.05 min, p=0.03).

Conclusions:

• Laparoscopic nephrectomy (LN) is a safer surgical option than open nephrectomy (ON) for inflammatory renal conditions (IRCs).
• LN offers benefits such as reduced complications, shorter hospitalizations, and decreased transfusion requirements.
• Optimizing outcomes with LN requires careful patient selection and significant surgeon expertise.
