OBJECTIVES: To determine the rate of incisional hernia after surgery for renal cell carcinoma, to compare the rate after open vs minimally invasive surgery and radical nephrectomy vs partial nephrectomy and to identify risk factors for incisional hernia.
MATERIALS AND METHODS: From the Renal Cell Cancer Database Sweden we identified all patients (n = 9,638) diagnosed with renal cell carcinoma in Sweden between January 2005 and November 2015. Of these, 6,417 were included in the analyses to determine comorbidity and subsequent diagnosis of or surgery for incisional hernia.
RESULTS: In all, 6,417 patients underwent surgery for renal cell carcinoma between January 2005 and November 2015, of these 5,216 (81%) underwent open surgery and 1,201 (19%) underwent minimally invasive surgery. Altogether 140 patients were diagnosed with incisional hernia. The cumulative rate of incisional hernia after 5 years was 5.2% (95% confidence interval [CI] = 4.0-6.4%) after open surgery and 2.4% (95% CI = 1.0-3.4%) after minimally invasive surgery (p < 0.05). In Cox proportional hazard analysis, age and left-sided surgery were associated with incisional hernia in the open surgery group (both p < 0.05), whereas in the minimally invasive group, no statistically significant risk factors for incisional hernia were found.
CONCLUSIONS: Open surgery for renal cell carcinoma is associated with a significantly higher risk for developing incisional hernia. If open surgery is the only option, care should be taken when choosing the approach and closing the wound. More studies are needed to find strategies to reduce the risk of abdominal wall complications following open kidney surgery.
