Short-term complications for percutaneous ultrasound-guided biopsy of renal masses in adult outpatients

Abstract

Background Ultrasound-guided percutaneous kidney tumor biopsy (UGPKB) plays an important role in the diagnosis of renal tumor but there are no consensuses with respect to the length and the extend of the post-biopsy observation period. Purpose To assess the short-term complication rate after UGPKB and to evaluate whether the onset of complications allows for the procedure to be performed in an outpatient setting with same-day discharge. Material and Methods Between March 2012 and March 2014, a total of 287 UGPKB were performed in an outpatient setting at a Danish university referral center. All patient records were retrospectively reviewed and post-biopsy complications as well as biochemical parameters were registered. Results The overall complication rate was 3.8% (11 patients). Major complications occurred in 1.0% of all cases (three patients); one patient with ongoing bleeding that required intervention and two patients with septicemia. Minor complications occurred in 2.8% of cases (eight patients); six patients with self-limiting gross hematuria, one patient with small asymptomatic subcapsular hematoma, and one patient with vasovagal syncope. The timing of both minor and major complication onset ranged from the time of biopsy and up to four days after discharge. Conclusion UGPKB of indeterminate renal masses in adult patients in an outpatient setting appears to be a safe procedure with a very low rate of major complications. Same-day discharge after renal mass biopsy seems feasible.

One hour observation of patients after image-guided percutaneous renal mass biopsy

“…5 Other similar studies found that a short observational period of 30 min to 4-h post-biopsy is feasible. 6,7 The implication of this could mean greater efficiency with patients leaving the hospital earlier and therefore requiring less funds and time from personnel for post-biopsy assistance. Frimpong et al concluded that observational period postbiopsy as little as 30 min was proven to be sufficient in cases where no imminent post-procedural complications was presented after a routine CT scan following a CT-guided thoracic biopsy.…”

“…5 Percutaneous renal tumour biopsy has been proven to be of use in an outpatient setting with a short post-biopsy observation time, when sudden onset complications are not present, proving it to be an efficient and reliable choice. 6 A study on short-duration post CT-guided thoracic biopsy observation time concluded that a 30-min observation time in patients without immediate complications related to the procedure was sufficient. 7 The outcome of this shortening of observation time regarding renal mass biopsy has not yet been evaluated.…”

A Comparison between Kidney Allograft Biopsies Performed by Nephrologists and Surgeons Versus Interventional Radiologists

“…including acute or chronic renal failure, delayed graft function, unexplained hematuria, and proteinuria [1][2][3]. Several complications have been associated with the procedure, such as perinephric hematoma, gross hematuria, hospitalization, arterio-venous fistula (AVF), and bowel perforations [3][4]. Most of the renal procedures, including renal biopsies, are part of the core curriculum of the Nephrology fellowship all over the world [5][6] and in most centers around the United States (US) [5][6][7].…”
