Introduction. Open surgical anatrophic nephrolithotomy (ANL) had been the standard treatment for large
renal calculi prior to the development of endoscopic devices and endoscopic techniques. A previous report described the efficacy of ureteroscopy-assisted retrograde
nephrostomy (UARN) and presented a case of
renal calculi successfully treated with UARN during
percutaneous nephrolithotomy (PCNL) in a patient after ANL. Case Presentation. A 61-year-old male with left
renal calculi was referred for further treatment. The patient was placed under general and
epidural anesthesia, in a Galdakao-modified Valdivia position. A flexible
ureteroscope (URS) was inserted, and a Lawson retrograde
nephrostomy puncture wire was advanced into the flexible URS. The
puncture wire then followed the route from the renal pelvis to the exit skin.
Calculus fragmentation was undertaken using a pneumatic lithotripter. Conclusions. UARN for PCNL was therefore found to be a safe, effective, and appropriate treatment for a patient presenting with
renal calculi after undergoing ANL.
