title: Management of nephrolithiasis after Cohen cross-trigonal and Glenn-Anderson advancement ureteroneocystostomy.
abstract: OBJECTIVE
  Ureteroneocystotomy is frequently performed for ureteral injury or vesicoureteral reflux. The Glenn-Anderson technique advances the ureteral orifice distal to its native position, while the Cohen technique crosses the orifice to the opposite trigone. Each treatment can alter access to the upper genitourinary tracts. We report our experience with subsequent nephrolithiasis in these patients.
  
  
  METHODS
  We performed a retrospective chart review of all patients treated with ureteroneocystotomy since 1980 who had nephrolithiasis.
  
  
  RESULTS
  Nephrolithiasis developed in 9 patients with prior Cohen ureteroneocystotomy and in 15 with prior Glenn-Anderson ureteroneocystotomy. Stones size was 2 to 20 mm (mean 6.4). In the Cohen group ureteroscopy was attempted and failed in 2 patients, requiring percutaneous nephrolithotomy. Attempted shock wave lithotripsy failed in 2 patients, of whom 1 required percutaneous nephrolithotomy and 1 required observation. Primary percutaneous nephrolithotomy was performed in 1 patient. One patient required nephrectomy for chronic pyelonephritis related to nephrolithiasis. Two patients had active stone disease and were awaiting further treatment, while 1 passed the stone. In the Glenn-Anderson group ureteroscopy was successful in all 4 attempts. Attempted shock wave lithotripsy in 2 patients was successful in 1. The other patient required subsequent percutaneous nephrolithotomy. Primary percutaneous nephrolithotomy was required in 2 patients. All other patients were asymptomatic and under observation.
  
  
  CONCLUSIONS
  Treatment for upper tract nephrolithiasis is effected by prior ureteroneocystotomy. Minimally invasive treatments were less successful after Cohen ureteroneocystotomy than after Glenn-Anderson ureteroneocystotomy. In this study patients with prior cross-trigonal ureteroneocystotomy required more invasive therapies for symptomatic nephrolithiasis.
