Ureteroscopy-assisted retrograde nephrostomy for an obese patient

Abstract

Obesity is associated with increased surgical morbidity and mortality. We previously reported on the usefulness of ureteroscopy assisted retrograde nephrostomy (UARN) and here we report a case of renal calculi successfully treated with UARN during percutaneous nephrolithotomy (PCNL) in an obese patient. A 63-year-old female with left renal calculi was referred to Department of Urology, Ohguchi Higashi General Hospital. Her body mass index was 34.0 kg/m 2 . Stone fragments were completely extracted. URS-assisted puncture from the renal collecting system to the skin under fluoroscopic guidance was a safe and easy procedure in our obese patient.
