Retroperitoneal Laparoscopic Kidney Biopsy: Technical Tips for a Minimally Invasive Approach

2011 
Abstract Objectives: Nowadays, ultrasound-guided percutaneous kidney biopsy (PKB) is the gold standard for renal biopsies. Nevertheless, PKB is still contraindicated by conditions such as bleeding diatheses, severe obesity, solitary kidney, uncontrolled hypertension, and previous failed attempts at PKB. In these cases, the laparoscopic approach may offer a valid and mini-invasive alternative to open biopsy. We describe our technique and report indications and outcomes of a consecutive series of retroperitoneal laparoscopic kidney biopsies (LKB). Materials and methods: In a retrospective review of patients who underwent LKB, we examined indications, outcomes, and complications, stratified according to the Clavien classification. Results: In all, 40 patients underwent LKB between 2001 and 2010 (mean age 58.85 years, SD 10.87). Mean serum creatinine at surgery was 3.02 mg/dL. Indications for LKB included coagulopathy (30%), polycystic kidney or multiple renal cysts (30%), solitary kidney (12.5%), and morbid ...
