Ureteropelvic junction obstruction in nephrolithiasis. An etiologic factor.
Obstruction is rarely accepted as the sole cause of calculi. We have reviewed 106 cases of nephrolithiasis for which surgery was performed at the St. Luke's Hospital Center during the past ten years. In 17 of these cases, obstruction of the ureteropelvic junction was demonstrated, an incidence of 16 per cent. We propose the theory that too frequently the responsible ureteropelvic junction obstruction goes undetected when a "routine" pyelolithotomy or nephrolithotomy is performed.
