Management of Urinary Calculi in Patients with a Solitary Kidney / 대한비뇨기과학회지

ABSTRACT

New therapies, percutaneous nephrostolithotomy(PNL), transurethral ureteroscopy (URS) and extracorporeal shock wave lithotripsy(ESWL), are revolutionizing the treatment of urinary tract calculi. Little are known, however, about the efficacy of managing the calculi in patients with a solitary kidney. We study 17 such calculi to determine which techniques can be utilized safely. effectively and efficiently in patients with a solitary kidney. Of 6 calculi treated by PNL, successful evacuation of the stones was achieved in 5 stones. Of 2 calculi treated by URS, successful evacuation of the stones in 1 stone. In the ESWL series of 9 calculi including the 2 stone fragmentation was record. In 2 staghorn stones, combination of PNL and ESWL were done. No significant complications were related in patients with a solitary kidney. Results and morbidity did not differ significantly from the treatment of calculi in patients with both kidneys. It is suggested that endourologic manipulation and ESWL in stone patients with a solitary renal unit are also as effective and safe as in patients with both renal unit, even though staghorn calculi, it may be handled safely by a combination of the 2 techniques as patients with both renal unit.
