Introduction:

Percutaneous Kidney Biopsy (PKB) has remained a gold standard procedure for obtaining further information about the diagnostic, prognostic and therapeutic processes of kidney diseases. Although PKB is a safe and useful procedure in terms of the diagnosis in nephrology practice, some complications still exist due to invasive nature of procedure. In this study, we evaluated the complications and identify factors possibly affecting bleeding complications associated with PKB. 

Material and methods:

This retrospective study includes patients who underwent PKB procedure at the Department of Pediatric Nephrology, Kayseri, Turkey from 2003 to 2016. We analyzed 397 biopsy reports, 93 of them who underwent kidney biopsy between 2011 and 2016 were included into study the further evaluation.  

Results:

41 girls and 52 boys with regular long-term follow were included into the study. The mean age was 10.0 ± 4, 3 years and 12, 0 ± 4, 4 at the time of biopsy and last follow-up, respectively. We detected obesity in 10 children, failure to thrive in 3 children, short stature in 13 children, hypertension in 9 children, prolonged PT and APTT required fresh frozen plasma prior to procedure in 3 children , and nephromegaly in 27 children. 17 children had gross hematuria and 59 patients had microscopic hematuria prior to procedure, then 9 new patients experienced with gross hematuria after the procedure. Renal ultrasound showed perinephric hematoma in 15 patients and arteriovenous fistula in 4 patients after the procedure. The occlusion of the fistulae was performed in 1 of them.  There is no relationship between bleeding complications and Hb value, obesity, blood pressure, acute kidney damage (GFR<60), hypoalbuminemia, PT, APTT. 

Conclusions:

Our study showed that PKB is a useful technique with usually minor and rarely life life-threatening complications like arteriovenous fistula requiring renal angiogram and closing with coil embolization.
